We report here on the software Hack Day organised at the 2014 SPIE conference on Astronomical Telescopes and Instrumentation in Montréal. The first ever Hack Day to take place at an SPIE event, the aim of the day was to bring together developers to collaborate on innovative solutions to problems of their choice. Such events have proliferated in the technology community, providing opportunities to showcase, share and learn skills. In academic environments, these events are often also instrumental in building community beyond the limits of national borders, institutions and projects. We show examples of projects the participants worked on, and provide some lessons learned for future events.

Publications of the International Society of Optical Engineering (SPIE) contain much of the relevant literature on Picture Archiving and Communications Systems (PACS) and related topics. In fact, many PACS-related articles indexed by the National Library of Medicine contain references to articles published by SPIE. Unfortunately, SPIE publications themselves are not indexed by the National Library of Medicine and thus can not be identified through Medline. The lack of a convenient mechanism for searching the SPIE literature is problematic for researchers in medical imaging. With the recent introduction on SPIE's Internet server of their Abstracts Online service and their In-CiteTM title and author searching software, the SPIE literature has become more accessible. However, the searching process is still a cumbersome and time consuming process, and it is not possible to perform key word searches of manuscript abstracts. In this paper we present results of our work on developing a mechanism to more thoroughly search SPIE publications for PACS-related articles.

The research field of smart materials and structures has been a distinct entity for two decades. Over the past ten years, the SPIE Industrial and Commercial Applications Conference has presented a Smart Structures Product Implementation Award at its annual symposium. This paper revisits the nine winning entries to date (1998-2007) and updates their status. The paper begins with a brief description of the original and current intent of the award and follows with a short overview of the evolution of smart structures, from research to products. The winning teams and their respective products are then described. The current status of the products is discussed based on publicly available information and input from the respective companies. Note however that it is not the purpose of the paper to rank the product winners in terms of success or sales. The paper concludes with an assessment of the larger trends in productization of smart structures technologies. The application "form" for the award as well as the evaluation criteria and suggestions for improving award application packages can be found in the appendix.

The impact of the computer on the practice of nuclear medicine has been felt primarily in the area of rapid dynamic studies. At this time it is difficult to find a clinic which routinely performs computer processing of static images. The general purpose digital computer is a sophisticated and flexible instrument. The number of applications for which one can use the computer to augment data acquisition, analysis, or display is essentially unlimited. In this light, the purpose of this exhibit is not to describe all possible applications of the computer in nuclear medicine but rather to illustrate those applications which have generally been accepted as practical in the routine clinical environment. Specifically, we have chosen examples of computer augmented cardiac, and renal function studies as well as examples of relative organ blood flow studies. In addition, a short description of basic computer components and terminology along with a few examples of non-imaging applications are presented
Full Text Available Nella prima età moderna l’abito degli ordini religiosi rappresenta un importante fattore di identità immediatamente riconoscibile. È per questo motivo che i gesuiti vennero visti con sospetto: essi erano infatti vestiti come preti secolari. Ignazio di Loyola decise di non avere alcun segno distintivo poiché voleva vivere nel mondo, ma la sua scelta venne male interpretata e intesa come una forma di dissimulazione: la mancanza di un abito specifico fu vista come strumentale all’assunzione di ogni tipo di travestimento e presto, in determinati contesti, i gesuiti vennero considerati vere e proprie spie. Ai loro occhi infatti indossare l’abito del paese che si accingevano a evangelizzare era anche il modo migliore, certo non l’unico, per entrare in contatto con le altre culture. In questo saggio si vuole prendere in esame tanto l’uso dell’abito come elemento della pratica evangelizzatrice nelle missioni quanto la leggenda nera che dalle origini circondò i gesuiti e vide proprio nell’abito uno dei segni più importanti della loro attitudine al travestimento. In the early modern age, the religious orders habit represent a very significant factor of identity to be immediately recognised, that’s why the Jesuits were looked with suspicion: in fact they were dressed as secular priests. Ignazio of Loyola decided not to have any distinctive sign because he wanted to live inside the world, but this choice was misinterpreted as a way of dissimulation: the lack of an habit was considered as a manner to assume any kind of disguise and soon Jesuits were considered as spies. In their opinion, to take the habit of the country they wanted to evangelize, was also the best way to be brought into contact with others cultures. In this paper I would like to consider either the Jesuits evangelisation practice in missions or the black legend that since the origins surrounded them considering also the habit one of the most important signal of their

One of the important aspects of SPIE is "Community Support and Outreach Education", which should raise awareness and interest in optics and photonics among the targeted communities and school children. Hence as part of SPIE IIT Madras student chapter, we carried out SPIE SOAP, a `School Outreach Activity Program'. Two types of schools were identified, one a high socio-economic status school and the other a low socio-economic status school having a majority of poor children. Optics related scientific experiments were demonstrated in these schools followed by oral quiz session to the students to assess the level of their knowledge before and after the experiments. We also clubbed this activity with "Vision Screening" and distribution of free spectacles for those children who live below poverty line. Out of the 415 children screened, 60.84% eyes were having normal vision, while 39.16% were found to have refractive errors (Myopia 35.78% and Hyperopia 3.38%) where some of them could not even read the board. Treatable eye diseases were also found in 0.72% of the children. The entire activity is been discussed and documented in this paper.

Full Text Available To improve the teaching-learning process in the Medicinal Chemistry course, new strategies have been incorporated into practical classes of this fundamental discipline of the pharmaceutical curriculum. Many changes and improvements have been made in the area of medicinal chemistry so far, and students should be prepared for these new approaches with the use of technological resources in this field. Practical activities using computational techniques have been directed to the evaluation of chemical and physicochemical properties that affect the pharmacokinetics of drugs. Their objectives were to allow students to know these tools, to learn how to access them, to search for the structures of drugs and to analyze results. To the best of our knowledge, this is the first study in Brazil to demonstrate the use of computational practices in teaching pharmacokinetics. Practical classes using Osiris and Molinspiration were attractive to students, who developed the activities easily and acquired better theoretical knowledge.Para melhorar o processo ensino-aprendizagem no curso de Química Medicinal novas estratégias estão sendo incorporadas às aulas práticas desta disciplina fundamental do currículo farmacêutico.

Digital computers were introduced to nuclear medicine research as an imaging modality in the mid-1960s. Widespread use of imaging computers (scintigraphic computers) was not seen in nuclear medicine clinics until the mid-1970s. For the user, the ability to acquire scintigraphic images into the computer for quantitative purposes, with accurate selection of regions of interest (ROIs), promised almost endless computational capabilities. Investigators quickly developed many new methods for quantitating the distribution patterns of radiopharmaceuticals within the body both spatially and temporally. The computer was used to acquire data on practically every organ that could be imaged by means of gamma cameras or rectilinear scanners. Methods of image processing borrowed from other disciplines were applied to scintigraphic computer images in an attempt to improve image quality. Image processing in nuclear medicine has evolved into a relatively extensive set of tasks that can be called on by the user to provide additional clinical information rather than to improve image quality. Digital computers are utilized in nuclear medicine departments for nonimaging applications also, Patient scheduling, archiving, radiopharmaceutical inventory, radioimmunoassay (RIA), and health physics are just a few of the areas in which the digital computer has proven helpful. The computer is useful in any area in which a large quantity of data needs to be accurately managed, especially over a long period of time

Applicability of our computer programs PASS and PharmaExpert to prediction of biological activity spectra of rather complex and structurally diverse phytocomponents of medicinal plants, both separately and in combinations has been evaluated. The web-resource on phytochemicals of 50 medicinal plants used in Ayurveda was created for the study of hidden therapeutic potential of Traditional Indian Medicine (TIM) (http://ayurveda.pharmaexpert.ru). It contains information on 50 medicinal plants, their using in TIM and their pharmacology activities, also as 1906 phytocomponents. PASS training set was updated by addition of information about 946 natural compounds; then the training procedure and validation were performed, to estimate the quality of PASS prediction. It was shown that the difference between the average accuracy of prediction obtained in leave-5%-out cross-validation (94,467%) and in leave-one-out cross-validation (94,605%) is very small. These results showed high predictive ability of the program. Results of biological activity spectra prediction for all phytocomponents included in our database are in good correspondence with the experimental data. Additional kinds of biological activity predicted with high probability provide the information about most promising directions of further studies. The analysis of prediction results of sets of phytocomponents in each of 50 medicinal plants was made by PharmaExpert software. Based on this analysis, we found that the combination of phytocomponents from Passiflora incarnata may exhibit nootropic, anticonvulsant and antidepressant effects. Experiments carried out in mice models confirmed the predicted effects of Passiflora incarnata extracts.

The decision to buy a computer is difficult. The wide variety of computing systems available makes that decision even harder because each of the systems has unique advantages and disadvantages. The following list contains many of the essentials any computer system for nuclear medicine should embody: (1) sophisticated and reliable hardware with sufficient memory capacity to acquire or display at least 128 x 128 static images or 64 x 64 dynamic studies and with the facility for adding extra hardware and peripheral equipment at a later date; (2) a well-proved, general-purpose, real-time operating system to which the programs specific to the gamma camera have been interfaced and which will allow expansion or modification of both hardware and software in the future; (3) a display exhibiting at least 128 x 128 resolution, a monochrome mode with extended gray scale, and perhaps color; a varied set of programmed image formats and hardware system that includes local refresher capabilities; (4) a high-level language, such as FORTRAN or BASIC, with the ability to directly access all data files and interact with system programs as well as a macroprogramming capability so the user may write his own programs for data manipulation and analysis; (5) a comprehensive yet generally applicable set of system programs to enable data acquisition, storage, analysis, and display. In addition to the above, one should expect the services of a team of well-trained maintenance technicians and engineers. The manufacturer should offer software support and exhibit a plan for continued development and upgrading of the software initially provided

The Human Genome Project and the explosion of high-throughput data have transformed the areas of molecular and personalized medicine, which are producing a wide range of studies and experimental results and providing new insights for developing medical applications. Research in many interdisciplinary fields is resulting in data repositories and computational tools that support a wide diversity of tasks: genome sequencing, genome-wide association studies, analysis of genotype-phenotype interactions, drug toxicity and side effects assessment, prediction of protein interactions and diseases, development of computational models, biomarker discovery, and many others. The authors of the present paper have developed several inventories covering tools, initiatives and studies in different computational fields related to molecular medicine: medical informatics, bioinformatics, clinical informatics and nanoinformatics. With these inventories, created by mining the scientific literature, we have carried out several reviews of these fields, providing researchers with a useful framework to locate, discover, search and integrate resources. In this paper we present an analysis of the state-of-the-art as it relates to computational resources for molecular medicine, based on results compiled in our inventories, as well as results extracted from a systematic review of the literature and other scientific media. The present review is based on the impact of their related publications and the available data and software resources for molecular medicine. It aims to provide information that can be useful to support ongoing research and work to improve diagnostics and therapeutics based on molecular-level insights.

The Computer Book of the Internal Medicine resident (CBIMR) is a computer program that was validated to analyze the acquisition of competences in teams of Internal Medicine residents. To analyze the characteristics of the rotations during the Internal Medicine residency and to identify the variables associated with the acquisition of clinical and communication skills, the achievement of learning objectives and resident satisfaction. All residents of our service (n=20) participated in the study during a period of 40 months. The CBIMR consisted of 22 self-assessment questionnaires specific for each rotation, with items on services (clinical workload, disease protocolization, resident responsibilities, learning environment, service organization and teamwork) and items on educational outcomes (acquisition of clinical and communication skills, achievement of learning objectives, overall satisfaction). Associations between services features and learning outcomes were analyzed using bivariate and multivariate analysis. An intense clinical workload, high resident responsibilities and disease protocolization were associated with the acquisition of clinical skills. High clinical competence and teamwork were both associated with better communication skills. Finally, an adequate learning environment was associated with increased clinical competence, the achievement of educational goals and resident satisfaction. Potentially modifiable variables related with the operation of clinical services had a significant impact on the acquisition of clinical and communication skills, the achievement of educational goals, and resident satisfaction during the specialized training in Internal Medicine.

With the increasing clinical importance of data-processing computers in nuclear medicine, the applications are now widely established. As for the output methods and output devices of data, processed pictures, and animation pictures, contrivance is necessary for the easy appreciation and utilization of the information obtained. In the cine-mode display of heart wall motion in particular, it is desirable to reproduce conveniently the output images as animated for image reading at any time or place. The apparatus for this purpose has been completed by using an ordinary home-use cassette VTR and a video monitor. The computer output pictures as nuclear medicine data are recorded in the VTR. Recording and reprocuction are possible only by a few additional components and some adjustments. Animation pictures such as the cine-mode display of heart wall motion can be conveniently reproduced for image reading, away from computers. (J.P.N.)

Artificial Neural Networks (ANN) may be a tool alternative and complementary to typical statistical analysis. However, in spite of many computer application of various ANN algorithms ready for use, artificial intelligence is relatively rarely applied to data processing. In this paper practical aspects of scientific application of ANN in medicine using the Statistical Neural Networks Computer program, were presented. Several steps of data analysis with the above ANN software package were discussed shortly, from material selection and its dividing into groups to the types of obtained results. The typical problems connected with assessing scintigrams by ANN were also described. (author)

The potential of 3-D nondestructive imaging techniques such as micro-computed tomography (micro-CT) was evaluated to study morphological patterns of the potential medicinal fungus Hericium coralloides (Basidiomycota). Micro-CT results were correlated with histological information gained from scanning electron microscopy (SEM) and light microscopy (LM). It is demonstrated that the combination of these imaging methods results in a more distinct picture of the morphology of the edible and potentially medicinal Hericium coralloides basidiomata. In addition we have created 3-D reconstructions and visualizations based on micro-CT imagery from a randomly selected part of the upper region of a fresh H. coralloides basidioma: Analyses for the first time allowed an approximation of the evolutionary effectiveness of this bizarrely formed basidioma type in terms of the investment of tissue biomass and its reproductive output (production of basidiospores). © 2015 by The Mycological Society of America.

Computers, personal digital assistants (PDA), and the Internet are widely used as resources in medical education and clinical care. Educators who intend to incorporate these resources effectively into residency education programmes can benefit from understanding how residents currently use these tools, their skills, and their preferences. The researchers sent questionnaires to 306 US family medicine residency programmes for all of their residents to complete. Respondents were 1177 residents from 125 (41%) programmes. Access to a computer was reported by 95% of respondents. Of these, 97% of desktop and 89% of laptop computers could access the Internet. Residents accessed various educational and clinical resources. Half felt they had 'intermediate' skills at Web searches, 23% had 'some skills,' and 27% were 'quite skilled.' Those under 30 years of age reported higher skill levels. Those who experienced a Web-based curriculum in medical school reported higher search skills and greater success in finding clinical information. Respondents preferred to use technology to supplement the didactic sessions offered in resident teaching conferences. Favourable conditions exist in family medicine residency programmes to implement a blend of traditional and technology-based learning experiences. These conditions include residents' experience, skills, and preferences.

Full Text Available Computer-based interactive clinical cases were introduced in 1999 to improve problem-solving abilities in undergraduate education in internal medicine at the University of Munich; the content of online cases was matched with the main lecture. Course credits were given for the successful processing of four cases; an additional eight cases were offered to the students for voluntary use. Only the required cases were used substantially (between 89% and 95% of all students whereas a minority of students (between 5% and 11% used the cases voluntarily. In spite of this predominantly extrinsic motivation, most students expressed a high level of intrinsic motivation and rated their self-reported learning success as high. The difficulty of cases was rated as appropriate. This was supported by quantitative data on the correctness of students' answers. In summary, the integration of computer-based cases into a face-to-face learning curriculum should be coupled with the course assessment framework.

The aim of this work is to present a simple, practical and efficient protocol for drug design, in particular Diabetes, which includes selection of the illness, good choice of a target as well as a bioactive ligand and then usage of various computer aided drug design and medicinal chemistry tools to design novel potential drug candidates in different diseases. We have selected the validated target dipeptidyl peptidase IV (DPP-IV), whose inhibition contributes to reduce glucose levels in type 2 diabetes patients. The most active inhibitor with complex X-ray structure reported was initially extracted from the BindingDB database. By using molecular modification strategies widely used in medicinal chemistry, besides current state-of-the-art tools in drug design (including flexible docking, virtual screening, molecular interaction fields, molecular dynamics, ADME and toxicity predictions), we have proposed 4 novel potential DPP-IV inhibitors with drug properties for Diabetes control, which have been supported and validated by all the computational tools used herewith.

To date, many symposia have been held on computer applications in nuclear medicine. Despite all of these efforts, an appraisal of the true utility of computers in the day-to-day practice of nuclear medicine is yet to be achieved. Now that the technology of data storage and processing in nuclear medicine has reached a high degree of sophistication, as evidenced by many reports in the literature, the time has come to develop a perspective on the proper place of computers in nuclear medicine practice. The paper summarizes various uses of a dedicated computer (Nuclear Data Med II) at our two institutions and comments on its clinical utility. (author)

There are no simple and validated instruments for evaluating the training of specialists. To analyze the reliability and validity of a computerized self-assessment method to quantify the acquisition of medical competences during the Internal Medicine residency program. All residents of our department participated in the study during a period of 28 months. Twenty-two questionnaires specific for each rotation (the Computer-Book of the Internal Medicine Resident) were constructed with items (questions) corresponding to three competence domains: clinical skills competence, communication skills and teamwork. Reliability was analyzed by measuring the internal consistency of items in each competence domain using Cronbach's alpha index. Validation was performed by comparing mean scores in each competence domain between senior and junior residents. Cut-off levels of competence scores were established in order to identify the strengths and weaknesses of our training program. Finally, self-assessment values were correlated with the evaluations of the medical staff. There was a high internal consistency of the items of clinical skills competences, communication skills and teamwork. Higher scores of clinical skills competence and communication skills, but not in those of teamwork were observed in senior residents than in junior residents. The Computer-Book of the Internal Medicine Resident identified the strengths and weaknesses of our training program. We did not observe any correlation between the results of the self- evaluations and the evaluations made by staff physicians. The items of Computer-Book of the Internal Medicine Resident showed high internal consistency and made it possible to measure the acquisition of medical competences in a team of Internal Medicine residents. This self-assessment method should be complemented with other evaluation methods in order to assess the acquisition of medical competences by an individual resident. Copyright © 2012 Elsevier Espa

It is shown that radiotracers can provide an opportunity to assess physiological processes of renal function by noninvasively following the path of a tracer as a function of time. Time-activity relationships obtained over seven anatomically defined regions are related to parameters of a seven compartment model employed to describe the renal clearance process. The values obtained for clinically significant parameters agree with known renal pathophysiology. Differentiation of failure of acute, chronic, and obstructive forms is indicated

Recent advances in the field of high-frequency power schemes for X-ray devices allow the creation of high-resolution instruments. At the department of electronic devices and Equipment of the St. Petersburg State Electrotechnical University, a model of a microfocus computer tomograph was developed. Used equipment allows to receive projection data with an increase up to 100 times. A distinctive feature of the device is the possibility of implementing various schemes for obtaining projection data.

Analysis of the results of teaching of clinical disciplines has in the long run an impact on the standard and value of medical care. It requires processing of quantitative and qualitative data. The selection of indicators which will be followed up and procedures used for their processing are of fundamental importance. The submitted investigation is an example how to use possibilities to process results of effectiveness analysis in teaching internal medicine by means of computer technique. As an indicator of effectiveness the authors selected the percentage of students who had an opportunity during the given period of their studies to observe a certain pathological condition, and as method of data collection a survey by means of questionnaires was used. The task permits to differentiate the students' experience (whether the student examined the patient himself or whether the patient was only demonstrated) and it makes it possible to differentiate the place of observation (at the university teaching hospital or regional non-teaching hospital attachment). The task permits also to form sub-groups of respondents to combine them as desired and to compare their results. The described computer programme support comprises primary processing of the output of the questionnaire survey. The questionnaires are transformed and stored by groups of respondents in data files of suitable format (programme SDFORM); the processing of results is described as well as their presentation as output listing or on the display in the interactive way (SDRESULT programme). Using the above programmes, the authors processed the results of a survey made among students during and after completion of the studies in a series of 70 recommended pathological conditions. As an example the authors compare results of observations in 20 selected pathological conditions important for the diagnosis and therapy in primary care in the final stage of the medical course in 1981 and 1985.

In 1965, Gordon Moore, a co-founder of Intel, said that new memory chips have twice the capacity of prior chips, and that new chips are released every 18 to 24 months. This statement has become known as Moore’s law. Moore’s law means that memory size increases exponentially. More generally, the exponential growth of computers has applied not only to memory size, but also to many computer capabilities, and since 1965, Moore’s law has remained remarkably accurate. Further, this remarkable growth in capabilities has occurred with a steady decrease in price. Anyone who has even a little appreciation of exponential growth realizes that exponential growth cannot continue indefinitely. However, the history of computers is littered with ‘experts’ who have prematurely declared the end of Moore’s law. The quotation at the beginning of this section indicates that future growth of computers has often been underestimated. The exponential growth of computer capabilities has a very important implication for the management of a nuclear medicine department. The growth in productivity of the staff of a department is slow, especially when compared to the growth in capabilities of a computer. This means that whatever decision was made in the past about the balance between staff and computers is now out of date. A good heuristic is: always apply more computer capacity and less people to a new task. Or stated more simply, hardware is ‘cheap’, at least with respect to what you learned in training or what you decided last time you considered the balance between hardware and ‘peopleware’.
Previously, a decision to purchase computing equipment for nuclear medicine usually required evaluation of the 'local' needs. With the advent of Pacs and state of the art computer techniques for image acquisition and manipulation, purchase and subsequent application is to become much more complex. Some of the current trends and future possibilities which may influence the choice and operation of computers within and outside the nuclear medicine environment is discussed. (author)
Although quality assurance activities have become well established for the hardware found in nuclear medicine little attention has been paid to computer software. This paper outlines some of the problems that exist and indicates some of the solutions presently under development. The major thrust has been towards establishment of programming standards and comprehensive documentation. Some manufacturers have developed installation verification procedures which programmers are urged to use as models for their own programs. Items that tend to cause erroneous results are discussed with the emphasis for error detection and correction being placed on proper education and training of the computer operator. The concept of interchangeable data files or 'software phantoms' for purposes of quality assurance is discussed. (Author)

Drug discovery involves the simultaneous optimization of chemical and biological properties, usually in a single small molecule, which modulates one of nature's most complex systems: the balance between human health and disease. The increased use of computer-aided methods is having a significant impact on all aspects of the drug-discovery and development process and with improved methods and ever faster computers, computer-aided molecular design will be ever more central to the discovery process.
The primary purpose of this conference was to present and critically evaluate new and ongoing research on the generation and transmission of intense microwave pulses. Significant progress was reported on high-power, high-current relativistic klystron amplifier research and design. Other work presented at the conference, include research on a high-power relativistic magnetron driven by a high-current linear induction accelerator, derivation of a Pierce-type dispersion relation describing the interaction of an intense relativistic electron beam with a corrugated cylindrical slow-wave structure, experiments on an X-band backward-wave cyclotron maser oscillator, and observation of frequency chirping in a free electron laser amplifier. Other presentations included work on multiwave Cerenkov generator experiments, analysis of resonance characteristics of slow-wave structures in high-power Cerenkov devices, linear analysis and numerical simulation of Doppler-shifted cyclotron harmonics in a cyclotron autoresonance klystron, high-power virtual cathode oscillator theory and experiments, design of a sixth-harmonic gyrofrequency multiplier as a millimeter-wave source, and experiments on dielectric-loaded and multiwave slotted gyro-TWT amplifiers. A review was presented on innovative concepts which employ high-power microwaves in propulsion of space vehicles. Separate abstracts were prepared for 34 papers of this conference
In 1990 Professor Wolfe after his SPIE presidency trekked the world, even making it as far as post-communist Poland, to see (in the visible and maybe in infrared - who knows) the work of optical scientists hidden behind the iron curtain. I am not sure if he was ready for how different that world was at this time, but for sure he was very inquisitive and eager to learn about the nuances of Poland right after the fall of communism. He met, visited with and encouraged young and old scientists from Poland, Russia, Hungary and Lithuania to add their expertise to the scientific conversations happening in the West. His mission in Poland was to invite us all, and he was ready to help us achieve our dreams. I was one of those he encouraged. This talk is my personal reflection of Professor Wolfe as an encouraging and sometimes brave SPIE pioneer - a stranger in a strange land - and as an energetic, caring SPIE president, Optical Sciences professor and human being. Disclaimer: Professor Bill Wolfe's contributions to the field of radiometry are well known and very well recognized. This conference is a tribute to him. However, my paper is not on radiometry; rather, I wish to illustrate the adventurous, caring and positive Bill Wolfe that helped me find my way to the American desert Southwest.

ECT is a mathematical and physical concept, an instrument, a radionuclide tracer technique, a research procedure and it is certainly both an old (Kuhl began his work in the late fifties) and a new concept. It also has great and unique potential as a diagnostic technique. It is interesting that the basic principles of medical CT were exemplified and developed in Nuclear Medicine by Kuhl and coworkers and the concept of ''physiologic or function tomography'' provides a technique to advance the original charter of Nuclear Medicine in the use of radionuclides for the measure of metabolism and physiologic function

This paper reviews the methods, benefits and challenges associated with the adoption and translation of computational fluid dynamics (CFD) modelling within cardiovascular medicine. CFD, a specialist area of mathematics and a branch of fluid mechanics, is used routinely in a diverse range of safety-critical engineering systems, which increasingly is being applied to the cardiovascular system. By facilitating rapid, economical, low-risk prototyping, CFD modelling has already revolutionised research and development of devices such as stents, valve prostheses, and ventricular assist devices. Combined with cardiovascular imaging, CFD simulation enables detailed characterisation of complex physiological pressure and flow fields and the computation of metrics which cannot be directly measured, for example, wall shear stress. CFD models are now being translated into clinical tools for physicians to use across the spectrum of coronary, valvular, congenital, myocardial and peripheral vascular diseases. CFD modelling is apposite for minimally-invasive patient assessment. Patient-specific (incorporating data unique to the individual) and multi-scale (combining models of different length- and time-scales) modelling enables individualised risk prediction and virtual treatment planning. This represents a significant departure from traditional dependence upon registry-based, population-averaged data. Model integration is progressively moving towards 'digital patient' or 'virtual physiological human' representations. When combined with population-scale numerical models, these models have the potential to reduce the cost, time and risk associated with clinical trials. The adoption of CFD modelling signals a new era in cardiovascular medicine. While potentially highly beneficial, a number of academic and commercial groups are addressing the associated methodological, regulatory, education- and service-related challenges.

Over the last centuries, there were many important discoveries in medicine that were crucial for gaining a better understanding of several physiological processes. Molecular modelling techniques are powerful tools that have been successfully used to analyse and interface medicinal chemistry studies with electrochemical experimental results. This special combination can help to comprehend medicinal chemistry problems, such as predicting biological activity and understanding drug action mechanisms. Electrochemistry has provided better comprehension of biological reactions and, as a result of many technological improvements, the combination of electrochemical techniques and biosensors has become an appealing choice for pharmaceutical and biomedical analyses. Therefore, this review will briefly outline the present scope and future advances related to the integration of electrochemical and medicinal chemistry approaches based on various applications from recent studies.

The use of halogens in therapeutics dates back to the earliest days of medicine when seaweed was used as a source of iodine to treat goiters. The incorporation of halogens to improve the potency of drugs is now fairly standard in medicinal chemistry. In the past decade, halogens have been recognized as direct participants in defining the affinity of inhibitors through a noncovalent interaction called the halogen bond or X-bond. Incorporating X-bonding into structure-based drug design requires computational models for the anisotropic distribution of charge and the nonspherical shape of halogens, which lead to their highly directional geometries and stabilizing energies. We review here current successes and challenges in developing computational methods to introduce X-bonding into lead compound discovery and optimization during drug development. This fast-growing field will push further development of more accurate and efficient computational tools to accelerate the exploitation of halogens in medicinal chemistry.

Precision Medicine is about selecting the right therapy for the right patient, at the right time, specific to the molecular targets expressed by disease or tumors, in the context of patient's environment and lifestyle. Some of the challenges for delivery of precision medicine in oncology include biomarkers for patient selection for enrichment-precision diagnostics, mapping out tumor heterogeneity that contributes to therapy failures, and early therapy assessment to identify resistance to therapies. PET/computed tomography offers solutions in these important areas of challenges and facilitates implementation of precision medicine. Copyright © 2016 Elsevier Inc. All rights reserved.

In clinical computed tomography (CT), regular quality assurance (QA) has been required. This study is to evaluate the MTF for analyzing the spatial resolution using AAPM phantom in CT exam. The dual source somatom definition flash (siemens healthcare, forchheim, Germany), the brilliance 64 (philips medical system Netherlands) and aquilion 64 (toshiba medical system, Japan) were used in this study. The quantitative evaluation was performed using the image J (wayne rasband national institutes of health, USA) and chart method which is measurement of modulation transfer function (MTF). In MTF evaluation, the spatial frequencies corresponding to the 50% MTF for the CT systems were 0.58, 0.28, and 0.59 mm-1, respectively and the 10% MTF for the CT systems were 1.63, 0.89, and 1.21 mm-1, respectively. This study could evaluate the characteristic of spatial resolution of MTF using chart method, suggesting the quantitative evaluation method using the data.

The applications of computers to biological and biomedical problem solving goes back to the very beginnings of computer science, automata theory , and mathematical biology . With the advent of more versatile and powerful computers, biological and biomedical applications of computers have proliferated so rapidly that it would be virtually impossible to compile a comprehensive review of all developments in this field. Limitations of computer simulations in biology have also come under close scrutiny, and claims have been made that biological systems have limited information processing power . Such general conjectures do not, however, deter biologists and biomedical researchers from developing new computer applications in biology and medicine. Microprocessors are being widely employed in biological laboratories both for automatic data acquisition/processing and modeling; one particular area, which is of great biomedical interest, involves fast digital image processing and is already established for rout...

The original motivation for this round table was the realization that there is a very real and urgent problem of transferring existing software, from systems which are no longer supported, to newer systems which are still being developed. Given that so many companies have gone out of business, and given that the whole market for computer systems attached to gamma cameras is in a state of considerable change, it seemed very opportune to raise this issue now, so that users and manufacturers could start, in collaboration, to develop some of the tools needed to facilitate such program transfers. However, one of the tools needed- a formalism in describing clinical algorithms, should be of considerable significance in its own right. Surely the time was now ripe for a collaborative venture in this area. It was hoped that this round table had raised some issues which both users and manufactureres could consider, and then take some coordinated action. There is now an awareness that the life of the software should be longer than the life of the hardware on which it is running, if this can be achieved. In order to tackle the associated problems we need some tools. The development of a formalism for the way in which clinical applications can be expressed is such a tool which should be developed, if possible. Another tool of particular importance is the use of software phantoms in order to test clinical procedures. (Author)

As part of a large medicinal chemistry program, we wish to develop novel selective estrogen receptor modulators (SERMs) as potential breast cancer treatments using a combination of experimental and computational approaches. However, one of the remaining difficulties nowadays is to fully integrate computational (i.e., virtual, theoretical) and medicinal (i.e., experimental, intuitive) chemistry to take advantage of the full potential of both. For this purpose, we have developed a Web-based platform, Forecaster, and a number of programs (e.g., Prepare, React, Select) with the aim of combining computational chemistry and medicinal chemistry expertise to facilitate drug discovery and development and more specifically to integrate synthesis into computer-aided drug design. In our quest for potent SERMs, this platform was used to build virtual combinatorial libraries, filter and extract a highly diverse library from the NCI database, and dock them to the estrogen receptor (ER), with all of these steps being fully automated by computational chemists for use by medicinal chemists. As a result, virtual screening of a diverse library seeded with active compounds followed by a search for analogs yielded an enrichment factor of 129, with 98% of the seeded active compounds recovered, while the screening of a designed virtual combinatorial library including known actives yielded an area under the receiver operating characteristic (AU-ROC) of 0.78. The lead optimization proved less successful, further demonstrating the challenge to simulate structure activity relationship studies.

Background Health science education faces numerous challenges: assimilation of knowledge, management of increasing numbers of learners or changes in educational models and methodologies. With the emergence of e-learning, the use of information and communication technologies (ICT) and Internet to improve teaching and learning in health science training institutions has become a crucial issue for low and middle income countries, including sub-Saharan Africa. In this perspective, the Faculty of Medicine and Biomedical Sciences (FMBS) of Yaoundé has played a pioneering role in Cameroon in making significant efforts to improve students’ and lecturers’ access to computers and to Internet on its campus. The objective is to investigate how computer literacy and the perception towards e-learning and its potential could contribute to the learning and teaching process within the FMBS academic community. Method A cross-sectional survey was carried out among students, residents and lecturers. The data was gathered through a written questionnaire distributed at FMBS campus and analysed with routine statistical software. Results 307 participants answered the questionnaire: 218 students, 57 residents and 32 lecturers. Results show that most students, residents and lecturers have access to computers and Internet, although students’ access is mainly at home for computers and at cyber cafés for Internet. Most of the participants have a fairly good mastery of ICT. However, some basic rules of good practices concerning the use of ICT in the health domain were still not well known. Google is the most frequently used engine to retrieve health literature for all participants; only 7% of students and 16% of residents have heard about Medical Subject Headings (MeSH). The potential of e-learning in the improvement of teaching and learning still remains insufficiently exploited. About two thirds of the students are not familiar with the concept of e-leaning. 84% of students and 58% of

The scaffold concept is widely applied in medicinal chemistry. Scaffolds are mostly used to represent core structures of bioactive compounds. Although the scaffold concept has limitations and is often viewed differently from a chemical and computational perspective, it has provided a basis for systematic investigations of molecular cores and building blocks, going far beyond the consideration of individual compound series. Over the past 2 decades, alternative scaffold definitions and organization schemes have been introduced and scaffolds have been studied in a variety of ways and increasingly on a large scale. Major applications of the scaffold concept include the generation of molecular hierarchies, structural classification, association of scaffolds with biological activities, and activity prediction. This contribution discusses computational approaches for scaffold generation and analysis, with emphasis on recent developments impacting medicinal chemistry. A variety of scaffold-based studies are discussed, and a perspective on scaffold methods is provided.

This summer BMSTU SPIE Student Chapter have decided to visit Kabardino-Balkaria Republic of Caucasus (Russia) and spent there a week with children in a camp. It was called Summer school. We decided to organize it in order to engage talented and curious children in Optics and to show them how science could be funny. Education and entertainment program included such activities as lectures, optical demonstrations, laser games, hiking in the forest, and others. As a result children had a good time outdoors, learned interesting facts about optics and lasers, and of course found new friends who are keen to know more too. Four Chapter members and about 70 children of age 10-16 took part in this event.

The Faculty of Medicine, Suez Canal University clinical skills lab was established in 1981 as the first skills lab in Egypt to cope with innovation in medical education adopted since school inauguration in 1978. Students are trained using their peers or models. Training is done weekly, guided by checklists tested for validity and reliability and updated regularly. Students receive immediate feedback on their performance. Recently, the number of students has increased, leading to challenges in providing adequate supervision and training experiences. A project to design and implement a computer-assisted training (CAT) system seemed to be a plausible solution. To assess the quality of a newly developed CAT product, faculty and students' satisfaction with it, and its impact on the learning process. The project involved preparation of multimedia video-films with a web interface for links of different scientific materials. The project was implemented on second year students. A quality check was done to assess the product's scientific content, and technical quality using questionnaires filled by 84 faculty members (139 filled forms) and 175 students (924 filled forms). For assessment of impact, results of examinations after project implementation were compared with results of 2nd year students of previous 3 years. More faculty (96.3%) were satisfied with the product and considered its quality good to excellent, compared to 93.9% of students, p < 0.001. Most faculty (76.2%) have agreed on its suitability for self-learning, while most students considered the product would be suitable after modification. The percentage of students' failures was lower after project implementation, compared to previous 3 years, p < 0.05. CAT materials developed for training of second year students in skills lab proved to be of good scientific content and quality, and suitable for self-learning. Their use was associated with lower failure rates among students. A randomized trial is recommended

This study focuses on clinically assigned prospective estimated pretest probability and pretest perception of legal risk as independent variables in the ordering of multidetector computed tomographic (MDCT) head scans. Our primary aim is to measure the association between pretest probability of a significant finding and pretest perception of legal risk. Secondarily, we measure the percentage of MDCT scans that physicians would not order if there was no legal risk. This study is a prospective, cross-sectional, descriptive analysis of patients 18 years and older for whom emergency medicine physicians ordered a head MDCT. We collected a sample of 138 patients subjected to head MDCT scans. The prevalence of a significant finding in our population was 6%, yet the pretest probability expectation of a significant finding was 33%. The legal risk presumed was even more dramatic at 54%. These data support the hypothesis that physicians presume the legal risk to be significantly higher than the risk of a significant finding. A total of 21% or 15% patients (95% confidence interval, ±5.9%) would not have been subjected to MDCT if there was no legal risk. Physicians overestimated the probability that the computed tomographic scan would yield a significant result and indicated an even greater perceived medicolegal risk if the scan was not obtained. Physician test-ordering behavior is complex, and our study queries pertinent aspects of MDCT testing. The magnification of legal risk vs the pretest probability of a significant finding is demonstrated.

Brain-computer interfaces (BCIs) acquire brain signals, analyze them, and translate them into commands that are relayed to output devices that carry out desired actions. BCIs do not use normal neuromuscular output pathways. The main goal of BCI is to replace or restore useful function to people disabled by neuromuscular disorders such as amyotrophic lateral sclerosis, cerebral palsy, stroke, or spinal cord injury. From initial demonstrations of electroencephalography-based spelling and single-neuron-based device control, researchers have gone on to use electroencephalographic, intracortical, electrocorticographic, and other brain signals for increasingly complex control of cursors, robotic arms, prostheses, wheelchairs, and other devices. Brain-computer interfaces may also prove useful for rehabilitation after stroke and for other disorders. In the future, they might augment the performance of surgeons or other medical professionals. Brain-computer interface technology is the focus of a rapidly growing research and development enterprise that is greatly exciting scientists, engineers, clinicians, and the public in general. Its future achievements will depend on advances in 3 crucial areas. Brain-computer interfaces need signal-acquisition hardware that is convenient, portable, safe, and able to function in all environments. Brain-computer interface systems need to be validated in long-term studies of real-world use by people with severe disabilities, and effective and viable models for their widespread dissemination must be implemented. Finally, the day-to-day and moment-to-moment reliability of BCI performance must be improved so that it approaches the reliability of natural muscle-based function. PMID:22325364

The introduction of mobile scintillation cameras has enabled the more immediate provision of nuclear medicine services in areas remote from the central nuclear medicine laboratory. Since a large number of such studies involve the use of a computer for data analysis, the concurrent problem of how to transmit those data to the computer becomes critical. A device is described using hard magnetic discs as the recording media and which can be wheeled from the patient's bedside to the central computer for playback. Some initial design problems, primarily associated with the critical timing which is necessary for the collection of gated studies, were overcome and the unit has been in service for the past two years. The major limitations are the relatively small capacity of the discs and the fact that the data are recorded in list mode. These constraints result in studies having poor statistical validity. The slow turn-around time, which results from the necessity to transport the system to the department and replay the study into the computer before analysis can begin, is also of particular concern. The use of this unit has clearly demonstrated the very important role that nuclear medicine can play in the care of the critically ill patient. The introduction of a complete acquisition and analysis unit is planned so that prompt diagnostic decisions can be made available within the intensive care unit. (author)

Methods of digital image processing are applied to problems in nuclear medicine imaging. The symmetry properties of central nervous system lesions are exploited in an attempt to determine the three-dimensional radioisotope density distribution within the lesions. An algorithm developed by astronomers at the end of the 19th century to determine the distribution of matter in globular clusters is applied to tumors. This algorithm permits the emission-computed-tomographic reconstruction of spherical lesions from a single view. The three-dimensional radioisotope distribution derived by the application of the algorithm can be used to characterize the lesions. The applicability to nuclear medicine images of ten edge detection methods in general usage in digital image processing were evaluated. A general model of image formation by scintillation cameras is developed. The model assumes that objects to be imaged are composed of a finite set of points. The validity of the model has been verified by its ability to duplicate experimental results. Practical applications of this work involve quantitative assessment of the distribution of radipharmaceuticals under clinical situations and the study of image processing algorithms

Full Text Available Precision medicine is an approach in medicine that takes into account individual differences in people's genes, environments, and lifestyle. This field of medicine redefines our understanding of disease onset and progression, treatment response, and health outcomes through the more precise measurement of molecular, environmental, and behavioral factors that contribute to health and disease. Undoubtedly, the advances in omics technologies including genomics, data collection and storage, computational analysis, and mobile health applications over the last decade produced significant progress for precision medicine. In fact, precision medicine is a platform for the growth of personalized medicine, wearable biosensors, mobile health, computational sciences, genomic singularity, and other omics technologies. In the pathway of precision medicine, mathematics and computational sciences will be revolutionized to overcome the challenges in Big Data. By the birth of precision medicine, novel therapeutic strategies for chronic complex diseases such as cardiovascular disease and cancers would be designed in Systems Medicine.

actual specimen. Low predicted bone density was lower than actual specimen. Differences were probably due to applied muscle and joint reaction loads, boundary conditions, and values of constants used. Work is underway to study this. Nonetheless, the results demonstrate three dimensional bone remodeling simulation validity and potential. Such adaptive predictions take physiological bone remodeling simulations one step closer to reality. Computational analyses are needed that integrate biological remodeling rules and predict how bone will respond over time. We expect the combination of computational static stress analyses together with adaptive bone remodeling simulations to become effective tools for regenerative medicine research
To understand the meaning of the term Systems Medicine and to distinguish it from seemingly related other expressions currently in use, such as precision, personalized, -omics, or big data medicine, its underlying history and development into present time needs to be highlighted. Having this development in mind, it becomes evident that Systems Medicine is a genuine concept as well as a novel way of tackling the manifold complexity that occurs in nowadays clinical medicine-and not just a rebranding of what has previously been done in the past. So looking back it seems clear to many in the field that Systems Medicine has its origin in an integrative method to unravel biocomplexity, namely, Systems Biology. Here scientist by now gained useful experience that is on the verge toward implementation in clinical research and practice.Systems Medicine and Systems Biology have the same underlying theoretical principle in systems-based thinking-a methodology to understand complexity that can be traced back to ancient Greece. During the last decade, however, and due to a rapid methodological development in the life sciences and computing/IT technologies, Systems Biology has evolved from a scientific concept into an independent discipline most competent to tackle key questions of biocomplexity-with the potential to transform medicine and how it will be practiced in the future. To understand this process in more detail, the following section will thus give a short summary of the foundation of systems-based thinking and the different developmental stages including systems theory, the development of modern Systems Biology, and its transition into clinical practice. These are the components to pave the way toward Systems Medicine.

There is a paucity of data regarding emergency department (ED) provider type and computed tomography (CT) scan use in the evaluation of pediatric patients with abdominal pain without trauma. The purpose of this retrospective single community hospital study was to determine if there was a difference in CT use between emergency medicine physicians (EMPs) and pediatricians (PEDs) in all patients younger than 18 years with abdominal pain without trauma who presented to the ED during the study period. The study included 165 patients. EMPs saw 83 patients and used CT in 31 compared with PEDs who saw 82 patients and used CT in 12 (P = .002). EMPs used CT significantly more frequently than PEDs in the designated sample. Economic pressures may cause changes in ED provider type in community and rural hospitals and this study shows that ED provider type may affect medical decision making, including CT use.

Systems medicine holds many promises, but has so far provided only a limited number of proofs of principle. To address this road block, possible barriers and challenges of translating systems medicine into clinical practice need to be identified and addressed. The members of the European Cooperation in Science and Technology (COST) Action CA15120 Open Multiscale Systems Medicine (OpenMultiMed) wish to engage the scientific community of systems medicine and multiscale modelling, data science and computing, to provide their feedback in a structured manner. This will result in follow-up white papers and open access resources to accelerate the clinical translation of systems medicine. © The Author 2017. Published by Oxford University Press.

Myocardial infarction (MI) is a leading cause of premature morbidity and mortality worldwide. Determining which patients will experience heart failure and sudden cardiac death after an acute MI is notoriously difficult for clinicians. The extent of heart damage after an acute MI is informed by cardiac imaging, typically using echocardiography or sometimes, cardiac magnetic resonance (CMR). These scans provide complex data sets that are only partially exploited by clinicians in daily practice, implying potential for improved risk assessment. Computational modelling of left ventricular (LV) function can bridge the gap towards personalised medicine using cardiac imaging in patients with post-MI. Several novel biomechanical parameters have theoretical prognostic value and may be useful to reflect the biomechanical effects of novel preventive therapy for adverse remodelling post-MI. These parameters include myocardial contractility (regional and global), stiffness and stress. Further, the parameters can be delineated spatially to correspond with infarct pathology and the remote zone. While these parameters hold promise, there are challenges for translating MI modelling into clinical practice, including model uncertainty, validation and verification, as well as time-efficient processing. More research is needed to (1) simplify imaging with CMR in patients with post-MI, while preserving diagnostic accuracy and patient tolerance (2) to assess and validate novel biomechanical parameters against established prognostic biomarkers, such as LV ejection fraction and infarct size. Accessible software packages with minimal user interaction are also needed. Translating benefits to patients will be achieved through a multidisciplinary approach including clinicians, mathematicians, statisticians and industry partners. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

With the increasing clinical importance of data-processing computers in nuclear medicine, the applications are now widely established. As for the output methods and output devices of data, processed pictures, and animation pictures, contrivance is necessary for the easy appreciation and utilization of the information obtained. In the cine-mode display of heart wall motion in particular, it is desirable to reproduce conveniently the output images as animated for image reading at any time or place. The apparatus for this purpose has been completed by using an ordinary home-use cassette VTR and a video monitor. The computer output pictures as nuclear medicine data are recorded in the VTR. Recording and reprocuction are possible only by a few additional components and some adjustments. Animation pictures such as the cine-mode display of heart wall motion can be conveniently reproduced for image reading, away from computers.

This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The kissing-loop RNA motif is thought to modulate different steps in the retroviral life cycle. Using an RNA folding protocol developed under this project, the authors are studying the folding of the potential kissing-loop motif in HIV. Using only limited information on base-springs, and the constraints based on the connectivities, they are modeling the structure and the flexibility of this particular structural motif and have developed three predicted structures with low conformational energy. Following on the earlier work which analyzed correlated mutations in the V3 loop of HIV, they have developed an evolutionary model which incorporates non-independent mutations at different sequence positions in model sequences. This model takes into account the effects of the phylogenetic tree on the analysis of mutations, and shows a higher correspondence of correlated positions with structurally adjacent positions in the model than previous analyses. Additional research under this project has dealt with analyzing the dynamics of HIV in vivo. Using some simple models and patient data, they were able to establish for the first time some quantitative estimates of HIV dynamics in vivo.
Linear tomography has been well known since the thirties of the last century. Before and alter World War II attempts of taking cross sections were done radiographically, but image quality was extremely poor. About 1960 A.M. Cormack developed a possibility to measure body densities for radiation therapy. After having attempted digitization of x-ray intensities during tissue penetration, G.N. Hounsfield constructed the first scanner in 1972 - in the first run only to examine the head. Improvements of technology lead to a series of generations of scanners which ended in the development of spiral CT and multi-slice detectors. In veterinary medicine the first papers on the use of CT in small animals were published by clinicians in the United States and in Germany nearly at the same time in 1980. A number of reports appeared afterwards from clinicians worldwide. The technique for examination of the horse was first described in the United States in 1986; in Europe the first CT scanner examining horses was established in Utrecht. At the Radiology Clinic of the University of Veterinary Medicine, Vienna, the first scanner for clinical use started to operate in summer 1993. The diagnostic possibilities improved in 1997 by introduction of a large animal weight bearing table. A new spiral CT has been put into operation in February 2001. CT has dramatically improved diagnostic accuracy in diagnostic imaging and lead to advanced therapy and prognosis for the patient in many specialist fields of veterinary medicine, e.g. neurosurgery, neurology, oncology, or orthopedics.

X-radiography and ultrasound imaging are well established and widely used in veterinary practice, but it is not the same situation with radioisotope imaging. In veterinary practice the above mentioned methods of nuclear medicine are developed only in two countries in Europe. That is not doubt due, so bar, to the difficulties in obtaining satisfactory supply of radioisotopes and to the relatively high cost of scanning equipment. However, in collaboration with the Department of Radiation Protection and Nuclear Medicine of the Medical Faculty in Zagreb, Croatia, we have chance to develop the use of those methods in clinical veterinary practice in Zagreb. That is way in this paper an overview of the application of radioisotopes imaging in veterinary medicine is given. In small animals skeletal changes, lung perusions, brain lesions, space occupying lesions in the liver and its function and hearth function can be usefully searched by a gamma camera and its associated computer. In equine practice scintigraphy of bones, liver, hearth, pulmonary circulation and ventilation is described. The largest amount of radioactive material is used during gamma camera scanning of the skeletons of horses. In this cases the radiation dose 1-2 m from the animal is approximately 3 μSv/h. That is why the protection of personal involved in radioisotope scanning in veterinary medicine must be also regulated by low of radiation protection. Also, the animals should be confined to a controlled area for 2-3 days after scanning before being returned to their owners. After this period the area must be cleaned. (author)

Holistic integrative medicine is the road to the future of the development of burn medicine. Not only burn medicine, but also human medicine gradually enters the era of holistic integrative medicine. Holistic integrative medicine is different from translational medicine, evidence-based medicine or precision medicine, which integrates the most advanced knowledge and theories in medicine fields with the most effective practices and experiences in clinical specialties to form a new medical system.
This review will summarize the effectiveness of computed tomography, ultrasound, and nuclear medicine imaging procedures in several different disease processes. The results indicate: (1) CT is clearly better than ultrasound for diseases of the adrenal gland and pancreas; (2) for patients with gynecologic malignancies, CT and ultrasound are approximately equivalent in their ability to define treatment options effectively; (3) in the liver, the differences among the three modalities are less marked and are disease specific. For example, for patients with colon cancer the increased effectiveness of CT relative to ultrasound or nuclear medicine is small. For patients with breast cancer, the difference is greater; (4) for patients suspected to have a focal source of sepsis, CT is slightly better than ultrasound or nuclear medicine. In these patients, however, when nuclear medicine images are obtained on a rectilinear scanner, the results are significantly worse compared to nuclear medicine images on a LFOV gamma camera or to ultrasound. As a result of the above studies and concommitant statistical analyses, several conclusions can be drawn about optimum experimental design and statistical approaches for comparing imaging modalities

Full Text Available Natural products and traditional medicines are of great importance. Such forms of medicine as traditional Chinese medicine, Ayurveda, Kampo, traditional Korean medicine, and Unani have been practiced in some areas of the world and have blossomed into orderly-regulated systems of medicine. This study aims to review the literature on the relationship among natural products, traditional medicines, and modern medicine, and to explore the possible concepts and methodologies from natural products and traditional medicines to further develop drug discovery. The unique characteristics of theory, application, current role or status, and modern research of eight kinds of traditional medicine systems are summarized in this study. Although only a tiny fraction of the existing plant species have been scientifically researched for bioactivities since 1805, when the first pharmacologically-active compound morphine was isolated from opium, natural products and traditional medicines have already made fruitful contributions for modern medicine. When used to develop new drugs, natural products and traditional medicines have their incomparable advantages, such as abundant clinical experiences, and their unique diversity of chemical structures and biological activities.

Many informed consent studies demonstrate that research subjects poorly retain and understand information in written consent documents. Previous research in multimedia consent is mixed in terms of success for improving participants' understanding, satisfaction, and retention. This failure may be due to a lack of a community-centered design approach to building the interventions. The goal of this study was to gather information from the community to determine the best way to undertake the consent process. Community perceptions regarding different computer-based consenting approaches were evaluated, and a computer-based consent was developed and tested. A second goal was to evaluate whether participants make truly informed decisions to participate in research. Simulations of an informed consent process were videotaped to document the process. Focus groups were conducted to determine community attitudes towards a computer-based informed consent process. Hybrid focus groups were conducted to determine the most acceptable hardware device. Usability testing was conducted on a computer-based consent prototype using a touch-screen kiosk. Based on feedback, a computer-based consent was developed. Representative study participants were able to easily complete the consent, and all were able to correctly answer the comprehension check questions. Community involvement in developing a computer-based consent proved valuable for a population-based genetic study. These findings may translate to other types of informed consents, including those for trials involving treatment of genetic disorders. A computer-based consent may serve to better communicate consistent, clear, accurate, and complete information regarding the risks and benefits of study participation. Additional analysis is necessary to measure the level of comprehension of the check-question answers by larger numbers of participants. The next step will involve contacting participants to measure whether understanding of

The Essenes were a Jewish sect, which flourished around the first century. We have limited our study to hygienic and medical aspects, as documented in the works of Josephus Flavius, Philo of Alexandria, and Pliny the Elder; Josephus and Philo were personally in contact with these sectarian Jews. We have described the regimen of life of these communities, who lived in strictly organised fashion, their meals taken in common, their bathing in cold water, their clothing, the Sabbath rest, the lavatories, and more. Most Essenes remained single, they adopted however small children, and educated them in accordance to their principles. There was no private property, but old people and sick residents were taken care of by the community. The Essenes, as well as the Therapeuts described by Philo, were knowledgeable in medical lore, they treasured old books and studied the virtues of medicinal plants. There is no clear-cut consensus whether the Essenes, the Therapeuts, and the Qumran residents were one and the same sect, or whether they were similar sub-sects. The calm, strictly regulated and frugal way of life of the Essenes enabled them to attain old age, often beyond 100 years.

After 5 y of collecting data on diagnostic reference levels (DRLs), the Nuclear Safety and Radiation Protection French Inst. (IRSN) presents the analyses of this data. The analyses of the collected data for radiology, computed tomography (CT) and nuclear medicine allow IRSN to estimate the level of regulatory application by health professionals and the representativeness of current DRL in terms of relevant examinations, dosimetric quantities, numerical values and patient morphologies. Since 2004, the involvement of professionals has highly increased, especially in nuclear medicine, followed by CT and then by radiology. Analyses show some discordance between regulatory examinations and clinical practice. Some of the dosimetric quantities used for the DRL setting are insufficient or not relevant enough, and some numerical values should also be reviewed. On the basis of these findings, IRSN formulates recommendations to update regulatory DRL with current and relevant examination lists, dosimetric quantities and numerical values. (authors)

Affective computing (AC) is concerned with emotional interactions performed with and through computers. It is defined as "computing that relates to, arises from, or deliberately influences emotions". AC enables investigation and understanding of the relation between human emotions and health as well as application of assistive and useful technologies in the medical domain. 1) To review the general state of the art in AC and its applications in medicine, and 2) to establish synergies between the research communities of AC and medical informatics. Aspects related to the human affective state as a determinant of the human health are discussed, coupled with an illustration of significant AC research and related literature output. Moreover, affective communication channels are described and their range of application fields is explored through illustrative examples. The presented conferences, European research projects and research publications illustrate the recent increase of interest in the AC area by the medical community. Tele-home healthcare, AmI, ubiquitous monitoring, e-learning and virtual communities with emotionally expressive characters for elderly or impaired people are few areas where the potential of AC has been realized and applications have emerged. A number of gaps can potentially be overcome through the synergy of AC and medical informatics. The application of AC technologies parallels the advancement of the existing state of the art and the introduction of new methods. The amount of work and projects reviewed in this paper witness an ambitious and optimistic synergetic future of the affective medicine field.

computer-aided learning (CAL) is increasingly used to deliver teaching, but few studies have evaluated its impact on learning within geriatric medicine. We developed and implemented CAL packages on falls and continence, and evaluated their effect on student performance in two medical schools. traditional ward based and didactic teaching was replaced by blended learning (CAL package combined with traditional teaching methods). Examination scores were compared for cohorts of medical students receiving traditional learning and those receiving blended learning. Control questions were included to provide data on cohort differences. in both medical schools, there was a trend towards improved scores following blended learning, with a smaller number of students achieving low scores (P learning was associated with improvement in student examination performance, regardless of the setting or the methods adopted, and without increasing teaching time. Our findings support the use of CAL in teaching geriatric medicine, and this method has been adopted for teaching other topics in the undergraduate curriculum.
In extracts from a lecture given at McGill University, the author describes the rise of a marketing or corporate ethos in medicine, stemming from economic constraints and the demographic pressures of aging populations in the U.S., Canada, and the United Kingdom. To counter the trend to corporate rather than public policy making in medicine, he advocates a holistic approach to health care, a revival of interest in preventive health, and encouragement of the self-help movement. Owen calls for a reorientation of medical attitudes so that traditional moral values of medicine present a "counterweight to the mechanistic, technological, cost-effectiveness of the market place."

While many studies have evaluated whether or not factual information can be effectively communicated using computer-aided tools, none has focused on establishing and changing students' attitudes toward international animal-health issues. The study reported here was designed to assess whether educational modules on an interactive computer CD elicited a change in veterinary students' interest in and attitudes toward international animal-health issues. Volunteer veterinary students at seven universities (first-year students at three universities, second-year at one, third-year at one, and fourth-year at two) were given by random assignment either an International Animal Health (IAH) CD or a control CD, ParasitoLog (PL). Participants completed a pre-CD survey to establish baseline information on interest and attitudes toward both computers and international animal-health issues. Four weeks later, a post-CD questionnaire was distributed. On the initial survey, most students expressed an interest in working in the field of veterinary medicine in another country. Responses to the three pre-CD questions relating to attitudes toward the globalization of veterinary medicine, interest in foreign animal disease, and inclusion of a core course on international health issues in the veterinary curriculum were all positive, with average values above 3 (on a five-point scale where 5 represented strong agreement or interest). Almost all students considered it beneficial to learn about animal-health issues in other countries. After students reviewed the IAH CD, we found a decrease at four universities, an increase at one university, and no change at the remaining two universities in students' interest in working in some area of international veterinary medicine. However, none of the differences was statistically significant.

Recent improvements in the understanding of the physiologic and biologic mechanisms of health and disease have led to an expansion of nuclear medicine applications both in clinical studies and research. Advances in radiopharmaceutical development, instrumentation and computer processing have resulted in the implementation of Positron Emission Tomography for clinical studies, and improved treatments with radiopharmaceuticals particularly in cancer patients. There has also been an dramatic increase in the techniques available with nuclear medicine to detect and measure cellular biologic events in-vivo, which have important implications in clinical and basic science research. Nuclear medicine studies provide unique information on human physiology and remain an integral part of clinical medicine practice

Medical Physics 2.0 is a bold vision for an existential transition of clinical imaging physics in face of the new realities of value-based and evidencebased medicine, comparative effectiveness, and meaningful use. It speaks to how clinical imaging physics can expand beyond traditional insular models of inspection and acceptance testing, oriented toward compliance, towards team-based models of operational engagement, prospective definition and assurance of effective use, and retrospective evaluation of clinical performance. Organized into four sessions of the AAPM, this particular session focuses on three specific modalities as outlined below. CT 2.0: CT has been undergoing a dramatic transition in the last few decades. While the changes in the technology merits discussions of their own, an important question is how clinical medical physicists are expected to effectively engage with the new realities of CT technology and practice. Consistent with the upcoming paradigm of Medical Physics 2.0, this CT presentation aims to provide definitions and demonstration of the components of the new clinical medical physics practice pertaining CT. The topics covered include physics metrics and analytics that aim to provide higher order clinicallyrelevant quantification of system performance as pertains to new (and not so new) technologies. That will include the new radiation and dose metrics (SSDE, organ dose, risk indices), image quality metrology (MTF/NPS/d’), task-based phantoms, and the effect of patient size. That will follow with a discussion of the testing implication of new CT hardware (detectors, tubes), acquisition methods (innovative helical geometries, AEC, wide beam CT, dual energy, inverse geometry, application specialties), and image processing and analysis (iterative reconstructions, quantitative CT, advanced renditions). The presentation will conclude with a discussion of clinical and operational aspects of Medical Physics 2.0 including training and

Traditional teaching concepts in medical education do not take full advantage of current information technology. We aimed to objectively determine the impact of Tablet PC enhanced training on learning experience and MKSAP® (medical knowledge self-assessment program) exam performance. In this single center, prospective, controlled study final year medical students and medical residents doing an inpatient service rotation were alternatingly assigned to either the active test (Tablet PC with custom multimedia education software package) or traditional education (control) group, respectively. All completed an extensive questionnaire to collect their socio-demographic data, evaluate educational status, computer affinity and skills, problem solving, eLearning knowledge and self-rated medical knowledge. Both groups were MKSAP® tested at the beginning and the end of their rotation. The MKSAP® score at the final exam was the primary endpoint. Data of 55 (tablet n = 24, controls n = 31) male 36.4%, median age 28 years, 65.5% students, were evaluable. The mean MKSAP® score improved in the tablet PC (score Δ + 8 SD: 11), but not the control group (score Δ- 7, SD: 11), respectively. After adjustment for baseline score and confounders the Tablet PC group showed on average 11% better MKSAP® test results compared to the control group (plearning to their respective training programs.

A list of 136 plants used for medicinal purposes by the Mapuche Amerindians of Chile has been compiled. This is the first such list in English and is important due to the disappearance of Mapuche culture with increasing urbanisation. Some introduced plants have been incorporated into the traditional medicine of the Mapuche since the advent of European settlers but there is also a wealth of information about the uses of many indigenous species.

The use of evidence has become a force in American medicine to improve the quality of health care. Funding decisions from payers will demand studies with high-level evidence to support many of the costly interventions in medicine. Plastic surgery is certainly not immune to this national tidal wave to revamp the health care system by embracing evidence-based medicine in our practices. In scientific contributions of plastic surgery research, application of evidence-based principles should enhance the care of all patients by relying on science rather than opinions. In this article, the genesis of evidence-based medicine is discussed to guide plastic surgery in this new revolution in American medicine.

This article focuses on the essential roles played by intermolecular forces in mediating the interactions between chemical molecules and biological systems. Intermolecular forces constitute a key topic in chemistry programs, yet can sometimes seem disconnected from real-life applications. However, by taking a "supramolecular" view of medicinal chemistry and focusing on interactions between molecules, it is possible to come to a deeper understanding of recent developments in medicine. This allows us to gain a real insight into the interface between biology and chemistry—an interdisciplinary area that is crucial for the development of modern medicinal products. This article emphasizes a conceptual view of medicinal chemistry, which has important implications for the future, as the supramolecular approach to medicinal-chemistry products outlined here is rapidly allowing nanotechnology to converge with medicine. In particular, this article discusses recent developments including the rational design of drugs such as Relenza and Tamiflu, the mode of action of vancomycin, and the mechanism by which bacteria develop resistance, drug delivery using cyclodextrins, and the importance of supramolecular chemistry in understanding protein aggregation diseases such as Alzheimer's and Creutzfield Jacob. The article also indicates how taking a supramolecular approach will enable the development of new nanoscale medicines.

The annual frequency of nuclear medicine examinations is increasing worldwide. This is partly a consequence of the recently introduced single photon emission tomography, combined with computed tomography, and positron emission tomography, combined with computed tomography, techniques, which combine functional, metabolic and morphological information important for the diagnosis of many diseases. However, since the effective radiation dose is the sum of the dose of two components, the hybrid examinations result in increased patient exposure. Accordingly, their justification becomes mandatory. It starts with their clinical importance-the opportunity to resolve a clinical problem decisive for patients' management. Knowledge of the indications, contraindications and the examinations' limitations is the responsibility of the nuclear medicine physician, as well as the choice of the most adequate examination and protocol. In conclusion, the cost and the accessibility of the examinations should not be the principal consideration as opposed to the diagnostic value and the exposure. Flexible protocols and algorithms should be used for hybrid nuclear medicine examinations. (authors)

Full text: To gain insight into Internet usage as a potential means of communicating with clinicians. Method: 200 clinicians within the South Western Sydney Health Area were surveyed by mail. Questionnaire details included Internet access, frequency of access, interest in department web site, suitability of content and interest in electronic bookings. The total response rate was 37% (74/200). General Practitioners comprised 46% of the respondents, and specialists 54%. All respondents had access to the Internet (44% from home only, 8% from work, 48% from both locations), with 57% accessing the Web daily. There was a high overall interest by respondents in accessing a Nuclear medicine web site, particularly for information and results, but a relative reluctance to consider electronic bookings. The following table outlines the respondents in detail. Our results indicate that a Nuclear Medicine web site has the potential to be an effective means of communicating with clinicians.

It is a truth universally acknowledged that there is a problem with general medicine. Physicians have become increasingly specialised over the past 30 years or so, and specialist care has produced increasingly better outcomes for some patients. The patients left behind are looked after by general medicine, where demand is increasing, operational priority within hospitals is low, there is little professional kudos and recruitment is suffering. Three recent reports - Hospitals on the Edge?, the Future Hospital Commission report, and the Shape of Training report - have described the problems, but not articulated compelling solutions. Here, I discuss what is good about general medicine, what is bad and make suggestions for improvement. These involve getting specialities to take responsibility for care of appropriate admissions automatically and without delay, giving general physicians control over the service that they provide, and using well-chosen financial drivers to support movement in the right direction. © 2014 Royal College of Physicians.

The impact of veterinary medicines on the environment will depend on a number of factors including physicochemical properties, amount used and method of administration, treatment type and dose, animal husbandry practices, manure storage and handling practices, metabolism within the animal, and degradation rates in manure and slurry. Once released to the environment, other factors such as soil type, climate, and ecotoxicity also determine the environmental impact of the compound. The importance of individual routes into the environment for different types of veterinary medicines varies according to the type of treatment and livestock category. Treatments used in aquaculture have a high potential to reach the aquatic environment. The main routes of entry to the terrestrial environment are from the use of veterinary medicines in intensively reared livestock, via the application of slurry and manure to land, and by the use of veterinary medicines in pasture-reared animals where pharmaceutical residues are excreted directly into the environment. Veterinary medicines applied to land via spreading of slurry may also enter the aquatic environment indirectly via surface runoff or leaching to groundwater. It is likely that topical treatments have greater potential to be released to the environment than treatments administered orally or by injection. Inputs from the manufacturing process, companion animal treatments, and disposal are likely to be minimal in comparison. Monitoring studies demonstrate that veterinary medicines do enter the environment, with sheep dip chemicals, antibiotics, sealice treatments, and anthelmintics being measured in soils, groundwater, surface waters, sediment, or biota. Maximum concentrations vary across chemical classes, with very high concentrations being reported for the sheep dip chemicals. The degree to which veterinary medicines may adsorb to particulates varies widely. Partition coefficients (K(d)) range from low (0.61 L kg(-1)) to high
This article traces the history of nuclear medicine in the country from the time the first radioisotope laboratory was set up by the Philippine General Hospital about 1955, to the not too satisfactory present facilities acquired by hospitals for diagnosis, treatment and investigation of diseases. It is in research, the investigation of disease that is nuclear medicine's most important area. The Philippine Atomic Energy Commission (PAEC) has pioneered in the conducting of courses in the medical uses of radioisotopes. The local training of nuclear manpower has been continued and updated and foreign fellowships are availed of through the cooperation of IAEA. Quite a number are already trained also in the allied fields that support the practice of nuclear medicine. However the brain drain has seriously affected the number of trained staff of medical units. Discussed and presented is the growth of the medical use of radioisotopes which are locally produced by PAEC. In order to benefit from the full advantage that nuclear medicine can do to a majority of Filipinos, the government should extend its financial support in acquiring such facilities to equip strategic hospitals in the country and support training programs. The Philippine has the expertise to start the expansion but only with adequate provision of funds will our capacity turn into reality. (RTD)
Full Text Available The Computers in Biology and Medicine (CBM journal promotes the use of computing machinery in the fields of bioscience and medicine. Since the first volume in 1970, the importance of computers in these fields has grown dramatically, this is evident in the diversification of topics and an increase in the publication rate. In this study, we quantify both change and diversification of topics covered in. This is done by analysing the author supplied keywords, since they were electronically captured in 1990. The analysis starts by selecting 40 keywords, related to Medical (M (7, Data (D (10, Feature (F (17 and (AI (6 methods. Automated keyword clustering shows the statistical connection between the selected keywords. We found that the three most popular topics in CBM are: Support Vector Machine (SVM, Electroencephalography (EEG and IMAGE PROCESSING. In a separate analysis step, we bagged the selected keywords into sequential one year time slices and calculated the normalized appearance. The results were visualised with graphs that indicate the CBM topic changes. These graphs show that there was a transition from Artificial Neural Network (ANN to SVM. In 2006 SVM replaced ANN as the most important AI algorithm. Our investigation helps the editorial board to manage and embrace topic change. Furthermore, our analysis is interesting for the general reader, as the results can help them to adjust their research directions.

The treatise On Ancient Medicine attests that questions of method were being debated both in medicine and in philosophy and is important evidence of cross-discipline methodological controversy. The treatise On Ancient Medicine is the first attempt in the history of Greek thought to provide a detailed account of the development of a science from a starting point in observation and experience. The author of it criticizes philosophical physicians who attempt to systematized medicine by reducing it to the interaction of one or more of the opposites hot, cold, wet, and dry, factors. He regards the theory of his opponents as hypothesis(hypothesis). Medicine has long been in possession of both an archē and a hodos, a principle and a method, which have enabled it to make discoveries over a long period of time. As far as method is concerned, the traditional science of medicine attained the knowledge of the visible by starting from observation and experience, but it recommended the use of reasoning and analogies with familiar objects as a means of learning about the invisible. It also utilized inference from the visible to the visible(epilogismos) and inference from the visible to the invisible(analogismos). The use of analogy as a means of learning about the obscure was also part of the common heritage of early philosophy and medicine. But the author's use of the analogical method distinguishes it from Empedocles' well-known analogy comparisons of the eye to a lantern and the process of respiration to the operations of a clepsydra. According to the author, traditional science of medicine used functional analogy like wine example and cheese example to know the function of humors within the body and utilized structured analogy like a tube example and a cupping instrument example to acknowledge an organ or structure within the body. But the author didn't distinguish between the claim that medicine has a systematic method of making discoveries and very different claim that it

Regenerative medicine is a rapidly evolving multidisciplinary, translational research enterprise whose explicit purpose is to advance technologies for the repair and replacement of damaged cells, tissues, and organs. Scientific progress in the field has been steady and expectations for its robust clinical application continue to rise. The major thesis of this review is that the pharmacological sciences will contribute critically to the accelerated translational progress and clinical utility of regenerative medicine technologies. In 2007, we coined the phrase "regenerative pharmacology" to describe the enormous possibilities that could occur at the interface between pharmacology, regenerative medicine, and tissue engineering. The operational definition of regenerative pharmacology is "the application of pharmacological sciences to accelerate, optimize, and characterize (either in vitro or in vivo) the development, maturation, and function of bioengineered and regenerating tissues." As such, regenerative pharmacology seeks to cure disease through restoration of tissue/organ function. This strategy is distinct from standard pharmacotherapy, which is often limited to the amelioration of symptoms. Our goal here is to get pharmacologists more involved in this field of research by exposing them to the tools, opportunities, challenges, and interdisciplinary expertise that will be required to ensure awareness and galvanize involvement. To this end, we illustrate ways in which the pharmacological sciences can drive future innovations in regenerative medicine and tissue engineering and thus help to revolutionize the discovery of curative therapeutics. Hopefully, the broad foundational knowledge provided herein will spark sustained conversations among experts in diverse fields of scientific research to the benefit of all.

There are bioethical, institutional, economic, legal, and cultural obstacles to creating the robust-precompetitive-data resource that will be required to advance the vision of "precision medicine," the ability to use molecular data to target therapies to patients for whom they offer the most benefit at the least risk. Creation of such an "information commons" was the central recommendation of the 2011 report Toward Precision Medicine issued by a committee of the National Research Council of the USA (Committee on a Framework for Development of a New Taxonomy of Disease; National Research Council. Toward precision medicine: building a knowledge network for biomedical research and a new taxonomy of disease. 2011). In this commentary, I review the rationale for creating an information commons and the obstacles to doing so; then, I endorse a path forward based on the dynamic consent of research subjects interacting with researchers through trusted mediators. I assert that the advantages of the proposed system overwhelm alternative ways of handling data on the phenotypes, genotypes, and environmental exposures of individual humans; hence, I argue that its creation should be the central policy objective of early efforts to make precision medicine a reality.
Many nuclear medicine procedures, originally developed more than 20 years ago, are now performed with new radiopharmaceuticals or instruments; it is therefore apposite to reappraise what we are doing and why we are doing it. The clinical utility of nuclear medicine is discussed with reference, by way of example, to gated blood pools scans and myocardial perfusion imaging; the importance of the referred population for the outcome of studies is stressed. Attention is drawn to the likelohood that the detection of ischemia would be enhanced by the administration of nitroglycerin prior to rest thallium injection. Emphasis is also placed on the increasing acceptance of dual-tracer studies. The significance of expression of p-glycoprotein by some tumors for sestamibi imaging is discussed, and advances in respect of fluorodeoxyglucose imaging are reviewed. The final section covers issues relating to the development of new procedures, such as the value of nuclear medicine in the detection and characterization of tissue oxygen levels and the possible future role of nuclear medicine in the management of sleeping and eating disorders.

Hospital medicine (HM) is rapidly evolving into new clinical and nonclinical roles. Traditional internal medicine (IM) residency training likely does not optimally prepare residents for success in HM. Hospital medicine residency training tracks may offer a preferred method for specialized HM education. Internet searches and professional networks were used to identify HM training tracks. Information was gathered from program websites and discussions with track directors. The 11 HM tracks at academic medical centers across the United States focus mostly on senior residents. Track structure and curricular content are determined largely by the structure and curricula of the IM residency programs in which they exist. Almost all tracks feature experiential quality improvement projects. Content on healthcare economics and value is common, and numerous track leaders report this content is expanding from HM tracks into entire residency programs. Tracks also provide opportunities for scholarship and professional development, such as workshops on abstract creation and job procurement skills. Almost all tracks include HM preceptorships as well as rotations within various disciplines of HM. HM residency training tracks focus largely on quality improvement, health care economics, and professional development. The structures and curricula of these tracks are tightly linked to opportunities within IM residency programs. As HM continues to evolve, these tracks likely will expand to bridge clinical and extra-clinical gaps between traditional IM training and contemporary HM practice.

In radiography of the thorax and abdomen of a large animal, the extreme thickness of the body causes a large amount of scattered radiation, which makes it difficult to obtain sharp images. The image resolutions of radiographs obtained by applying conventional radiography, scanography and computed tomography [CT] on an equine thoracic phantom were compared. Tubes of various inside diameters, used to simulate the pulmonary vessels were placed in an equine thoracic phantom and radiographed by CT, scanography and conventional radiography so as to compare the various degrees of resolution of the images of the tubes obtained by these methods. CT and scanography both gave a higher resolution index than conventional radiography, and both provided recognizable images of tubes < 2 mm in diameter, which conventional radiography failed to do. Scanography and CT can be used to obtain high-quality images of the thorax and abdomen of large animals. The image quality was compared using the resolution index (RI). The RI would be a wholly practical and comprehensive index for resolution because it includes 3 factors, contrast, sharpness and magnification, and yet is easy to calculate
In this introduction to a special subsection of Theoretical Medicine and Bioethics comprising separate reviews of the Springer Handbook of the Philosophy of Medicine, The Routledge Companion to Philosophy of Medicine, and The Bloomsbury Companion to Contemporary Philosophy of Medicine, I compare the three texts with respect to their overall organization and their approach to the relation between the science and the art of medicine. I then indicate two areas that merit more explicit attention in developing a comprehensive philosophy of medicine going forward: health economics and systematic relations within the field as a whole. The reviews that follow speak for themselves.

The nature of the medical treatment of prisoners in the Gulag has emerged from accounts published by survivors. Over a period of 70 years some doctors entrusted with the medical care of prisoners failed to discharge their ethical duties, contributing to the prisoners' neglect and suffering. The medical profession must carefully examine what occurred and properly assign responsibility for ethical as well as unethical medical acts. Understanding the history of these ominous events will alert doctors worldwide to the importance of medical autonomy in the support of imprisoned patients. Images p1728-a p1729-a PMID:7820004

In the last of four articles giving a medical view of nuclear war, the attitudes towards civil defence and the psychological effects of nuclear war are examined. The general training and information programmes on civil defence in the West are briefly discussed particularly in relation to fallout shelters. Psychological reactions to the threat of attack, the discomforts of being confined in a fallout shelter, the large numbers of dead and injured who will not be rescued, an eventual emergence into a society where normal services and supplies are disrupted may well disable otherwise healthy survivors and hamper their efforts at recovery.

Recent advances in genomic profiling and sequencing of melanoma have provided new insights into the development of the basis for molecular biology to more accurately subgroup patients with melanoma. The development of novel mutation-targeted and immunomodulation therapy as a major component of precision oncology has revolutionized the management and outcome of patients with metastatic melanoma. PET imaging plays an important role in noninvasively assessing the tumor biological behavior, to guide individualized treatment and assess response to therapy. This review summarizes the recent genomic discoveries in melanoma in the era of targeted therapy and their implications for functional PET imaging. Published by Elsevier Inc.

Recent advances in genomics have led to the rapid and relatively inexpensive collection of patient molecular data including multiple types of omics data. The integration of these data with clinical measurements has the potential to impact on our understanding of the molecular basis of disease and on disease management. Systems medicine is an approach to understanding disease through an integration of large patient datasets. It offers the possibility for personalized strategies for healthcare through the development of a new taxonomy of disease. Advanced computing will be an important component in effectively implementing systems medicine. In this chapter we describe three computational challenges associated with systems medicine: disease subtype discovery using integrated datasets, obtaining a mechanistic understanding of disease, and the development of an informatics platform for the mining, analysis, and visualization of data emerging from translational medicine studies.

This paper describes several new visualization and interaction techniques that enable the use of virtual environments for routine medical purposes. A new volume-rendering method supports shaded and transparent visualization of medical image sequences in real-time with an interactive threshold definition. Based on these rendering algorithms two complementary segmentation approaches offer an intuitive assistance for a wide range of requirements in diagnosis and therapy planning. In addition, a hierarchical data representation for geometric surface descriptions guarantees an optimal use of available hardware resources and prevents inaccurate visualization. The combination of the presented techniques empowers the improved human-machine interface of virtual reality to support every interactive task in medical three-dimensional (3-D) image processing, from visualization of unsegmented data volumes up to the simulation of surgical procedures.

In the future vascular medicine will still have a great impact on health of people. It should be noted that the aging of the population does not lead to a dramatic increase in patient numbers, but will be associated with a changing spectrum of co-morbidities. In addition, vascular medical research has to include the intensive care special features of vascular patients, the involvement of vascular medicine in a holistic concept of fast-track surgery, a geriatric-oriented intensive monitoring and early geriatric rehabilitation. For the future acceptance of vascular medicine as a separate subject area under delimitation of cardiology and radiology is important. On the other hand, the subject is so complex and will become more complex in future specialisations that mixing of surgery and angiology is desirable, with the aim to preserve the vascular surgical knowledge and skills on par with the medical and interventional measures and further develop them. Only large, interdisciplinary guided vascular centres will be able to provide timely diagnosis and therapy, to deal with the growing multi-morbidity of the patient, to perform complex therapies even in an acute emergency and due to sufficient number of cases to present with well-trained and experienced teams. These requirements are mandatory to decrease patients' mortality step by step. Georg Thieme Verlag KG Stuttgart · New York.

This paper describes the laws and regulations that affect the practice of energy medicine. State law often has more impact on a health care practice than federal law, but federal law provides a common denominator among states. Device law is emphasized here because practitioners of energy medicine are more likely to use devices than drugs. For purposes of this paper, energy medicine is defined as practices that measure or benefit energy flow and overall energy in the body. This broad definition encompasses things as diverse as certain forms of exercise, measurement of meridian resistance, the use of electrical current or magnetic pulses to relieve pain, and the use of light, sound, scent, touch, position, or movement to stimulate the body's own electrical systems. What is of greatest importance in determining legal implications of a practice is whether there are any health-related claims. Two federal entities are pivotal. The Food and Drug Administration ("FDA") is authorized to protect health and safety and the Federal Trade Commission ("FTC") is authorized to protect consumers from false or misleading advertising. There are 5 things that FDA looks at: 1) intended use, 2) claims made in advertising and in labeling, 3) substantial equivalence to a predicate, 4) safety, and 5) effectiveness. A concern regarding any one of these can be the basis for denying clearance to market a device. The FTC looks at whether statements are true and substantiated and whether they might be misleading. The FTC often consults with the FDA on the interpretation of technical information.

The specialty of emergency medicine (EM) continues to experience a significant workforce shortage in the face of increasing demand for emergency care. In July 2009, representatives of the leading EM organizations met in Dallas for the Future of Emergency Medicine Summit. Attendees at the Future of Emergency Medicine Summit agreed on the following: 1) Emergency medical care is an essential community service that should be available to all; 2) An insufficient emergency physician workforce also represents a potential threat to patient safety; 3) Accreditation Council for Graduate Medical Education/American Osteopathic Association (AOA)-accredited EM residency training and American Board of Medical Specialties/AOA EM board certification is the recognized standard for physician providers currently entering a career in emergency care; 4) Physician supply shortages in all fields contribute to-and will continue to contribute to-a situation in which providers with other levels of training may be a necessary part of the workforce for the foreseeable future; 5) A maldistribution of EM residency-trained physicians persists, with few pursuing practice in small hospital or rural settings; 6) Assuring that the public receives high quality emergency care while continuing to produce highly skilled EM specialists through EM training programs is the challenge for EM's future; 7) It is important that all providers of emergency care receive continuing postgraduate education.

Plasma medicine is a rapidly evolving multidisciplinary field at the intersection of chemistry, biochemistry, physics, biology, medicine and bioengineering. It holds great potential in medical, health care, dentistry, surgical, food treatment and other applications. This multidisciplinary nature and variety of possible applications come along with an inherent and intrinsic complexity. Advancing plasma medicine to the stage that it becomes an everyday tool in its respective fields requires a fundamental understanding of the basic processes, which is lacking so far. However, some major advances have already been made through detailed experiments over the last 15 years. Complementary, computer simulations may provide insight that is difficult—if not impossible—to obtain through experiments. In this review, we aim to provide an overview of the various simulations that have been carried out in the context of plasma medicine so far, or that are relevant for plasma medicine. We focus our attention mostly on atomistic simulations dealing with plasma-biomolecule interactions. We also provide a perspective and tentative list of opportunities for future modelling studies that are likely to further advance the field.
The internet is a global collection of networked computers linked by a set of protocols which allows the otherwise disperate computer systems to communicate with each other. In contrast to text-only data available previously, the World Wide Web allows multimedia content to be available on the internet. Graphics can now likewise be used as links. The development of World Wide Web client software such as Mosaic, or the currently more popular Netscape Navigator, makes linking from one document to another (colloquially referred to as 'surfing the Net') fast and simple. While these software are commonly called Web browsers their function extends to the other internet services such as e-mail, file transfer protocol, remote login, Gopher and WAIS. A prototype application being developed as a case-based teaching file which could include clinical data and case discussion, aside of course from the nuclear medicine and related images. Contributions from various institutions can be made available on their own servers and linked together through hypertext. Examples of these are websites of the Mallinckrodt Institute of Radiology and the Joint Program in Nuclear Medicine of the Harvard Medical School. The university of Iowa also has its Virtual Hospital, a collection of clinical cases with radiologic images. Most major universities and medical centers have websites where information on on-going research, facilities and personnel are made available. Links to various special interest discussion groups (e.g. those developing the common image file format) are also accessible and the documents often contain further links to related fields in nuclear technology. The very nature of the hypertext transfer protocol of the World Wide Web makes it a relatively simple matter for a developer of a teaching system to include links to necessary resources. It is envisioned that an internet-based teaching module will be incorporated in some nuclear medicine training programs in the United States

Various sources purport an association between lumbar puncture and brainstem herniation in patients with intracranial mass effect lesions. Several organizations and texts recommend head computed tomography (CT) prior to lumbar puncture in selected patients. To review the evidence regarding the utility of obtaining head CT prior to lumbar puncture in adults with suspected bacterial meningitis. Observational studies report a risk of post-lumbar puncture brainstem herniation in the presence of intracranial mass effect (1.5%) that is significantly lower than that reported among all patients with bacterial meningitis (up to 13.3%). It is unclear from existing literature whether identifying patients with intracranial mass effect decreases herniation risk. Up to 80% of patients with bacterial meningitis experiencing herniation have no CT abnormalities, and approximately half of patients with intracranial mass effect not undergoing lumbar puncture herniate. Decision rules to selectively perform CT on only those individuals most likely to have intracranial mass effect lesions have not undergone validation. Despite recommendations for immediate antimicrobial therapy prior to imaging, data indicate an association between pre-lumbar puncture CT and antibiotic delays. Recent data demonstrate shortened door-to-antibiotic times and lower mortality from bacterial meningitis after implementation of new national guidelines, which restricted generally accepted CT indications by removing impaired mental status as imaging criterion. Data supporting routine head CT prior to lumbar puncture are limited. Physicians should consider selective CT for those patients at risk for intracranial mass effect lesions based on decision rules or clinical gestalt. Patients undergoing head CT must receive immediate antibiotic therapy. Published by Elsevier Inc.

The precision medicine as a new emerging area and therapeutic strategy has occurred and was practiced in the individual and brought unexpected successes, and gained high attentions from professional and social aspects as a new path to improve the treatment and prognosis of patients. There will be a number of new components to appear or be discovered, of which clinical bioinformatics integrates clinical phenotypes and informatics with bioinformatics, computational science, mathematics, and systems biology. In addition to those tools, precision medicine calls more accurate and repeatable methodologies for the identification and validation of gene discovery. Precision medicine will bring more new therapeutic strategies, drug discovery and development, and gene-oriented treatment. There is an urgent need to identify and validate disease-specific, mechanism-based, or epigenetics-dependent biomarkers to monitor precision medicine, and develop "precision" regulations to guard the application of precision medicine.

Although advances in information technology in the past decade have come in quantum leaps in nearly every aspect of our lives, they seem to be coming at a slower pace in the field of medicine. However, the implementation of electronic health records (EHR) in hospitals is increasing rapidly, accelerated by the meaningful use initiatives associated with the Center for Medicare & Medicaid Services EHR Incentive Programs. The transition to electronic medical records and availability of patient data has been associated with increases in the volume and complexity of patient information, as well as an increase in medical alerts, with resulting "alert fatigue" and increased expectations for rapid and accurate diagnosis and treatment. Unfortunately, these increased demands on health care providers create greater risk for diagnostic and therapeutic errors. In the near future, artificial intelligence (AI)/machine learning will likely assist physicians with differential diagnosis of disease, treatment options suggestions, and recommendations, and, in the case of medical imaging, with cues in image interpretation. Mining and advanced analysis of "big data" in health care provide the potential not only to perform "in silico" research but also to provide "real time" diagnostic and (potentially) therapeutic recommendations based on empirical data. "On demand" access to high-performance computing and large health care databases will support and sustain our ability to achieve personalized medicine. The IBM Jeopardy! Challenge, which pitted the best all-time human players against the Watson computer, captured the imagination of millions of people across the world and demonstrated the potential to apply AI approaches to a wide variety of subject matter, including medicine. The combination of AI, big data, and massively parallel computing offers the potential to create a revolutionary way of practicing evidence-based, personalized medicine.

Complementary medicines, including herbal medicines in Australia are regulated under therapeutics goods legislation. Based on risk, Australia has developed a two tiered approach to the regulation of therapeutic goods. Listed medicines are considered to be of lower risk than Registered medicines. Most, but not all, complementary medicines are Listed medicines. Managing the risk associated with therapeutic goods, including complementary medicines, is exerted through the processes of licensing of manufacturers; pre-market assessment of products; and post-market regulatory activity. Herbal medicines may be associated with low or high risk depending on the toxicity of ingredients, proposed dosage, appropriateness of the indications and claims for self-diagnosis and management and the potential for adverse reactions. Registered medicines are individually evaluated for safety, quality and efficacy before they are released onto the market. Listed medicines are individually assessed by the Therapeutic Goods Administration for compliance with legislation, they are not evaluated before release. They may only be formulated from ingredients that have undergone pre-market evaluation for safety and quality and are considered low risk. Listed complementary medicines may only carry indications and claims for the symptomatic relief of non-serious conditions, health maintenance, health enhancement and risk reduction. An important feature of risk management in Australia is that early market access for low risk complementary medicines is supported by appropriate post-market regulatory activity

Benefits of adopting good radiation practices in reducing the whole body radiation dose to the nuclear medicine personnel during (18)F-fluorodeoxyglucose positron emission tomography/computed tomography imaging.
Verma, Shashwat; Kheruka, Subhash Chand; Maurya, Anil Kumar; Kumar, Narvesh; Gambhir, Sanjay; Kumari, Sarita
Positron emission tomography has been established as an important imaging modality in the management of patients, especially in oncology. The higher gamma radiation energy of positron-emitting isotopes poses an additional radiation safety problem. Those working with this modality may likely to receive higher whole body doses than those working only in conventional nuclear medicine. The radiation exposure to the personnel occurs in dispensing the dose, administration of activity, patient positioning, and while removing the intravenous (i.v.) cannula. The estimation of radiation dose to Nuclear Medicine Physician (NMP) involved during administration of activity to the patient and technical staff assisting in these procedures in a positron emission tomography/computed tomography (PET/CT) facility was carried out. An i.v access was secured for the patient by putting the cannula and blood sugar was monitored. The activity was then dispensed and measured in the dose calibrator and administered to the patient by NMP. Personnel doses received by NMP and technical staff were measured using electronic pocket dosimeter. The radiation exposure levels at various working locations were assessed with the help of gamma survey meter. The radiation level at working distance while administering the radioactivity was found to be 106-170 μSv/h with a mean value of 126.5 ± 14.88 μSv/h which was reduced to 4.2-14.2 μSv/h with a mean value of 7.16 ± 2.29 μSv/h with introduction of L-bench for administration of radioactivity. This shows a mean exposure level reduction of 94.45 ± 1.03%. The radiation level at working distance, while removing the i.v. cannula postscanning was found to be 25-70 μSv/h with a mean value of 37.4 ± 13.16 μSv/h which was reduced to 1.0-5.0 μSv/h with a mean value of 2.77 ± 1.3 μSv/h with introduction of L-bench for removal of i.v cannula. This shows a mean exposure level reduction of 92.85 ± 1.78%. This study shows that good radiation practices are
If you go to a bookstore to look for information on a particular health problem you will have a choice between the "medicine" corner with scientific manuals for professionals and the "health" corner with all kinds of books about acupuncture, ayurveda, natural healing, homeopathy, nutrition, massage, and so on! How is it on the Net? Even a short tour will bring you a lot of "medical" information, but when you look for alternative approaches in the "health" corner you will be rather disappointed. Interesting sites are rare and the amount of information very sparse. In many cases the lists of therapists are seriously incomplete; professional therapists with long experience do not appear in them. Recommendations for alternative treatments are superficial and encourage the user to buy some specialties or some book. Many sites are inflated by just quoting other sites so that, in the end, the basic information is rather poor. As we know, "health" information is becoming increasingly important since patients want to take more responsibility for themselves. They look for alternative methods. Doctors too, as 46% of Swiss doctors use alternative methods in one way or another (Médecine et Hygiène, 1996). That is why we should not leave this part of the Internet in the hands of unqualified people. To some doctors, alternative medicine may seem a chaotic maelstrom of superstition and odd techniques. That is not so. Nearly every alternative therapy has a long tradition with its own rules and principles. All reliable therapists have undergone years of training and expect the same from their colleagues. Why should this search for quality not be present online? What is needed? Good quality information. The identity of the author must be clear (education, tradition, professional experience, training). As many schools claim to be "the only one", the user should be informed about the differences and conflicts between all the approaches. Ethical behavior must be encouraged: respect

Traditional herbal medicine plays a significant role in the treatment of epilepsy. Though herbal medicine is widely used in antiepileptic treatment, there is a lack of robust evidence for efficacy and toxicity of most herbs. Besides, the herbal medicine should be subject to evidence-based scrutiny. In this context, we present a review to introduce the effects of herbal medicine on epilepsy. However, hundreds of herbal medicines have been investigated in the available studies. Some commonly used herbal medicines for epilepsy have been listed in our study. The overwhelming majority of these data are based on animal experiments. The lack of clinical data places constraints on the clinical recommendation of herbal medicine.

The 9 (th) Revision of German Medical Licensing Regulations for Physicians has come into effect on October 1 (st) 2003. Social medicine was separated into the fields "occupational health, social medicine" and the various cross-sectional modules: epidemiology, biometry, medical computer science; health economics, health-care system, public health; prevention, health promotion; rehabilitation, physical medicine, naturopathic treatment. This paper studies the realisation of teaching in the field social medicine at German medical faculties. The survey was conducted in collaboration with the German Association for Social Medicine and Prevention (DGSMP). A survey was conducted at 38 institutes of 36 German medical faculties. The written questionnaire contained mostly selection items in which chances and barriers of the field were queried with supply items. Information about time scale, general conditions and resources was aked for. On the basis of the guidelines of the DGSMP, the topics to be taught were evaluated concerning their relevance and integration into education. The response rate was 68% (n=26). Social insurance, basic principles, responsibility in the Social Security Code and the different providers were judged as the most important topics. There was a strong demand for lecturing material. 82% (n=18) of the faculties wished to have specific material, for example e-learning, examples, lesson plans, curricula and also textbooks. 91% (n=19) of the faculties requested an exchange of information between the faculties concerning educational contents, motivation of students and e-learning. The realisation of teaching is different between the faculties concerning the number of hours, teaching methods and number of students per year. The motivation of the students is one of the problems, but also the lack of acceptance within the clinic. Specific resources and exchange between the faculties are necessary concerning e-learning, which is offered at only few faculties so

Biomedicine produces copious information it cannot fully exploit. Specifically, there is considerable need to integrate knowledge from disparate studies to discover connections across domains. Here, we used a Collaborative Filtering approach, inspired by online recommendation algorithms, in which non-negative matrix factorization (NMF) predicts interactions among chemicals, genes, and diseases only from pairwise information about their interactions. Our approach, applied to matrices derived from the Comparative Toxicogenomics Database, successfully recovered Chemical-Disease, Chemical-Gene, and Disease-Gene networks in 10-fold cross-validation experiments. Additionally, we could predict each of these interaction matrices from the other two. Integrating all three CTD interaction matrices with NMF led to good predictions of STRING, an independent, external network of protein-protein interactions. Finally, this approach could integrate the CTD and STRING interaction data to improve Chemical-Gene cross-validation performance significantly, and, in a time-stamped study, it predicted information added to CTD after a given date, using only data prior to that date. We conclude that collaborative filtering can integrate information across multiple types of biological entities, and that as a first step towards precision medicine it can compute drug repurposing hypotheses.
Nowadays nanotechnology has become a technological field with great potential since it can be applied in almost every aspect of modern life. One of the sectors where nanotechnology is expected to play a vital role is the field of medical science. The interaction of nanotechnology with medicine gave birth to a completely new scientific field called nanomedicine. Nanomedicine is a field that aims to use the nanotechnology tools and principles in order to improve human health in every possible way. Nanotechnology provides monitoring tools and technology platforms that can be used in terms of detection, diagnostic, bioanalysis and imaging. New nanoscale drug-delivery systems are constantly designed with different morphological and chemical characteristics and unique specificity against tumours, offering a less harmful approach alternative to chemo- and radiotherapies. Furthermore, nanotechnology has led to great breakthroughs in the field of tissue engineering, making the replacement of damaged tissues and organs a much feasible procedure. The thorough analysis of bio and non-bio interactions achieved by versatile nanotools is essential for the design and development of highly performed medical implants. The continuous revolution in nanotechnology will result in the fabrication of nanostructures with properties and functionalities that can benefit patient's physiology faster and more effectively than conventional medical procedures and protocols. The number of nanoscale therapeutical products is rapidly growing since more and more nanomedical designs are reaching the global market. However the nanotoxic impact that these designs can have on human health is an era that requires still more investigation. The development of specific guidance documents at a European level for the safety evaluation of nanotechnology products in medicine is strongly recommended and the need for further research in nanotoxicology is identified. Ethical and moral concerns also need to be

Shape Memory Alloys (SMAs) are unique materials able to undergo a thermomechanically induced, reversible phase transformation. Additionally, SMA are subject to two types of fatigue, that is structural fatigue due to cyclic loading as experienced by most materials, as well as actuation fatigue due to repeated thermally induced phase transformation. The evolution of multiple material characteristics is presented over the actuation fatigue lifetime of NiTiHf actuators, including the accumulation of irrecoverable strain, the evolution of internal voids, and the evolution of the effective modulus of the actuator. The results indicate that all three of these material characteristics are clearly interconnected and careful analysis of each of these characteristics can help to understand the evolution of the others, as well as help to understand how actuation fatigue leads to ultimate failure of the actuator.

Full Text Available This article is an attempt to relate the first three of Wilma Stockenstrom's collections of poetry to international Symbolism. First we discuss possible links between her work and Symbolism. The mam emphasis then falls on Stockenstrom’s method of Symbolism, the possible symbolist tone of her work and prominent symbolist motifs in her work. Finally we consider some manifestations of the symbolist oilier world in these collections. The conclusion arrived at is that Stockenstrom's earlier work shows many of the main characteristics of Symbolism so that her work can be regarded as a continuation of the symbolist tradition. This tradition undergoes three important transformations in her work: the European world of symbolist poetry is replaced by an archeologically rich but mute African world, modern science and technology replaces the medieval system of reference of Symbolism, and sound and musicality p la y a much smaller part in Stockenstrom's poetry. Stockenstrom's cynical, ironic tone, the use of opaque kafkaesque symbols, her emphasis on tentative visions, her distrust of language and her tendency to relativize frames of reference in the endings of her poems, show that Stockenstrom's poetry has already crossed the boundary to Modernism.

Some consider the terms "forensic" and "legal" medicine to be synonymous but this is counter to the title of the Faculty of Forensic and Legal Medicine or the dual strands for progression to fellowship of the Australian College of Legal Medicine. The paper examines a very brief historical background to legal medicine and develops a definition of the strands thereof, namely legal and forensic medicine. It demonstrates that the two are different components of the application of medical knowledge upon the legal system. Legal medicine has greater relevance to civil and tort law, impacting upon patient care, whereas forensic medicine relates to criminal law and damage to, or by, patients.

Full Text Available The practice of "evidence-based medicine" aims at the conscientious, explicit and judicious use of the current best evidence in making decisions about the individualised patient care. The clinical genetics evolved from translational genetics research and contributes to the clinical care of patients and families through evidence-based health care in managing inherited disorders through accurate diagnosis, molecular pathology and assessing phenotypic correlations. Translational genetics and genomics research has led to the development of powerful tools for clinical diagnosis, assessing individual's genomic profile for disease prediction/prevention, high-throughput genome-wide screening for predisposition and/or protection to complex medical conditions, and discovery and development of new drugs and vaccines. Gene mapping and deciphering pathogenic mutations have helped in unravelling the basic biological mechanisms leading to new drug discovery and development. Targeted pharmacotherapy is now possible for managing the highly penetrant multi-system dominantly inherited conditions. Notable examples include rapamycin (sirolimus in suppressing the mTOR pathway associated hamartomas in dominantly inherited cancer family syndromes and angiotensin converting enzyme receptor blockers (ACE-RB in preventing aortic dilatation in Marfan syndrome and related familial arteriopathies. The translational genomic research is the essential prerequisite for developing sound evidence-based diagnostic, therapeutic and prognostic clinical protocols for the practice of personalised clinical medicine.

Plath and Jonker continually wrote about mirror images, eyes and questions of identity. Different psychological theories surrounding this issue, including those of Winnicott, Jung and Lacan, are discussed. Plath’s “Mirror” and “Words” as well as Jonker’s “Op alle gesigte” are specifically examined. Concluding remarks reveal that a mental block, or crypt, will always force a poet to reword his/her trauma.

Europe, because of its geographical location, strategic position on trade routes, and colonial past, has a long history of caring for travellers' health. Within Europe, there is great diversity in the practice of travel medicine. Some countries have travel medicine societies and provisions for a periodic distribution of recommendations, but many countries have no national pre-travel guidelines and follow international recommendations such as those provided by the WHO. Providers of travel medicine include tropical medicine specialists, general practice nurses and physicians, specialist 'travel clinics', occupational physicians, and pharmacists. One of the core functions of the European Centre for Disease Prevention and Control-funded network of travel and tropical medicine professionals, EuroTravNet, is to document the status quo of travel medicine in Europe. A three-pronged approach is used, with a real-time online questionnaire, a structured interview with experts in each country, and web searching.
The body-mind dualism of somatic medicine is resolved through the concept of psychosomatic medicine. More unspecific descriptions such as "integrative medicine" (which does not clarify what should be integrated) or the "holistic approach" (which comes close to esoterics) suggest the unity of mind, body and soul, although the term "psycho-somatic" still reflects dualistic thinking. The American Psychosomatic Society has been considering a name change for years, partially to rid itself of the dualistic label, but so far these efforts have not resulted in a viable alternative. Engel's concept of biopsychosocial medicine supposes a triangular array of the body, mind, and social environment, setting body and mind into a relationship with each other and with a third party. Based on the physician-patient relationship (Balint), psychosomatic medicine can be understood in a broader sense as "relationship medicine," covering not only the use of the interpersonal relationship as a medical agent, but also a science of medicine that puts mind, body, and social environment into a theoretical framework of interrelations, with the perspective of integrating the different system levels. The translation processes among the system levels are, for example, addressed by biosemiotics (v. Uexküll). Both clinical medicine and medical research, if they intend to be psychosomatic, need to take these theoretical concepts into account and utilize them practically for (team)work with patients. Together with a clear differentiation from other cultures of (para)medicine, this can serve to develop a "psychosomatic identity."

Before scientific medicine appeared on the scene less than 200 years ago, alternative medicine existed side by side with what was considered to be college-certified medical practice. Surgery took a bit longer to become an academic discipline, looked down on by medical doctors and was, for a long time restricted to unqualified barbers. Since then, with the application of the scientific method, medicine has made, and is still making enormous strides. We do no...

Full Text Available Pharmaceutical expenditure growth has outpaced GDP and healthcare expenditure growth rates in Denmark as in most OECD countries for the last decade. A major part of this increase was due to high growth rates in specialist areas that are typically located in hospital settings. Yet the market for hospital medicines and their procurement are still poorly understood. The present paper characterises the market for hospital medicines in Denmark in terms of its organisation and developments between 2005 and 2009. In Denmark hospital medicines are publicly financed and procurement is centrally organised. 98% of all medicines administered at Danish public hospitals are purchased through a public procurement agency by means of public tenders. Using data on actual contract prices we decompose pharmaceutical expenditure growth into the contributions from newly introduced medicines, price and volume increases and use summary statistics to compare market performance in both sectors. The market for hospital medicine is more concentrated than the pharmaceutical retail sector and the share of generics and parallel imported products is significantly lower. Between 2005 and 2009 expenditures for hospital medicines more than doubled -accounting for almost 40% of the total Danish pharmaceutical market in 2009. Price increases however - although positive and higher than in the pharmaceutical retail sector - were only moderate. The majority of the expenditure growth was due to an increase in utilisation and the introduction of new medicines in the hospital sector. Centralised tendering may therefore have important implications for competition and industry structure in the long run.

It is a point when non-biological intelligence becomes more intelligent than humans and each generation of intelligent machines re-designs itself smarter. Beyond this point, there is a symbiosis between machines and humans. This co-existence will produce incredible impacts on medicine that its sparkles could be seen in healthcare industry and the future medicine since 2025. Ray Kurzweil, the great futurist, suggested that three revolutions in science and technology consisting genetic and molecular science, nanotechnology, and robotic (artificial intelligence provided an exponential growth rate for medicine. The "exponential medicine" is going to create more disruptive technologies in healthcare industry. The exponential medicine shifts the paradigm of medical philosophy and produces significant impacts on the healthcare system and patient-physician relationship.

This paper is a critique of 'integrative medicine' as an ideal of medical progress on the grounds that it fails to realise the cognitive value of alternative medicine. After a brief account of the cognitive value of alternative medicine, I outline the form of 'integrative medicine' defended by the late Stephen Straus, former director of the US National Centre for Complementary and Alternative Medicine. Straus' account is then considered in the light of Zuzana Parusnikova's recent criticism of 'integrative medicine' and her distinction between 'cognitive' and 'opportunistic' engagement with alternative medicine. Parusnikova warns that the medical establishment is guilty of 'dogmatism' and proposes that one can usefully invoke Karl Popper's 'critical rationalism' as an antidote. Using the example of Straus, I argue that an appeal to Popper is insufficient, on the grounds that 'integrative medicine' can class as a form of cognitively-productive, critical engagement. I suggest that Parusnikova's appeal to Popper should be augmented with Paul Feyerabend's emphasis upon the role of 'radical alternatives' in maximising criticism. 'Integrative medicine' fails to maximise criticism because it 'translates' alternative medicine into the theories and terminology of allopathic medicine and so erodes its capacity to provide cognitively-valuable 'radical alternatives'. These claims are then illustrated with a discussion of 'traditional' and 'medical' acupuncture. I conclude that 'integrative medicine' fails to exploit the cognitive value of alternative medicine and so should be rejected as an ideal of medical progress. Copyright © 2013 Elsevier Ltd.

To develop 6 conjugate agents of the moribund antibiotic sulfamethoxazole (SMZ) joined to 6 individual monoterpenes, followed by protocols of medicinal chemistry as potent antibacterials, against multidrug resistant (MDR) human gruesome pathogenic bacteria. Antibacterial activities of the proposed conjugates were ascertained by the 'prediction of activity spectra of substances' (PASS) program. Drug-likeness parameters and toxicity profiles of conjugates were standardized with the Lipinski rule of five, using cheminformatic tools, Molsoft, molinspiration, OSIRIS and ProTox. Antibacterial activities of individual chemicals and conjugates were examined by targeting the bacterial folic acid biosynthesis enzyme, dihydropteroate synthases (DHPSs) of bacteria, Bacillus anthracis, Escherichia coli, Staphylococcus aureus, Streptococcus pneumoniae and Mycobacterium tuberculosis, with 3D structures of DHPSs from protein data bank. According to the PASS program, biological spectral values of conjugate-2, conjugate-5 and conjugate-6 were ascertained effective with 'probably active' or 'Pa' value > 0.5, for anti-infective and antituberculosic activities. Using molecular docking against 5 cited bacterial DHPSs, effective docking scores of 6 monoterpenes in the specified decreasing order (kcal/mol): -9.72 (eugenol against B. anthracis), -9.61 (eugenol against S. pneumoniae), -9. 42 (safrol, against B. anthracis), -9.39 (thymol, against M. tuberculosis), -9.34 (myristicin, against S. pneumoniae) and -9.29 (thymol, against B. anthracis); whereas the lowest docking score of SMZ was -8.46kcal/mol against S. aureus DHPS. Similarly, effective docking scores of conjugates were as specified (kcal/mol.): -10.80 (conjugate-4 consisting SMZ+safrol, against M. tuberculosis), -10.78 (conjugate-5 consisting SMZ+thymol, against M. tuberculosis), -10.60 (conjugate-5 against B. anthracis), -10.26 (conjugate-2 consisting SMZ+ eugenol, against M. tuberculosis), -10.25 (conjugate-5, against S
Precision medicine is now recognized globally as a major new era in medicine. It is being driven by advances in genomics and other 'omics' but also by the desire on the part of both health systems and governments to offer more targeted and cost-effective care. However, it faces a number of challenges, from the economics of developing more expensive companion diagnostics to the need to educate patients and the public on the advantages for them. New models of both R&D and care delivery are needed to capture the scientific, clinical and economic benefits of precision medicine.

A review of multiple parameters including membership in professional organizations, corresponding authorship of medicinal chemistry journal articles, and representation in professional and leadership positions reveals that the percentage of women who participate in professional medicinal chemistry activities is less than 20%. These surrogate demographics are consistent across organizations, regions in the world and the various parameters evaluated, and parallel statistics compiled on the broader participation of women in all STEM fields. As in other STEM fields, a leaky pipeline is also evident. Suggestions for how to encourage and support women in medicinal chemistry in order to provide a more balanced representation are provided.

Genomic medicine offers the promise of more effective diagnosis and treatment of human diseases. Genome sequencing early in the course of disease may enable more timely and informed intervention, with reduced healthcare costs and improved long-term outcomes. However, genomic medicine strains current models for demonstrating value, challenging efforts to achieve fair payment for services delivered, both for laboratory diagnostics and for use of molecular information in clinical management. Current models of healthcare reform stipulate that care must be delivered at equal or lower cost, with better patient and population outcomes. To achieve demonstrated value, genomic medicine must overcome many uncertainties: the clinical relevance of genomic variation; potential variation in technical performance and/or computational analysis; management of massive information sets; and must have available clinical interventions that can be informed by genomic analysis, so as to attain more favorable cost management of healthcare delivery and demonstrate improvements in cost-effectiveness.

An official medicines control laboratory (OMCL) provides an important contribution to combat counterfeit and illegal medicines. The OMCL supports the competent authorities in controlling the quality of authorised medicinal products in the legal supply chain. For detecting counterfeit medicines in the legal supply chain, a risk-based approach in choice of products is conducted. Furthermore, the OMCL analyses suspicious medicines from the illegal supply chain for any other authority. The chemical analysis of a suspicious sample is needed to identify such a sample as a counterfeit medicine. The analytical results are fundamental for the evaluation of the legal status of the product and for the assessment of it's inherent hazard to public health. The global market of illegal medicines is rapidly changing. Therefore a good national and international working liaison and co-operation between laboratories and authorities is obligatory to protect public health. The OMCL provides important knowledge of new trends in counterfeit and illegal medicines. Hence, it is an essential part in surveillance of medicinal products. The efficient networking enables prompt official interventions. Thus, risks for the public health by substandard medicines were reduced. Beside the chemical analysis, the OMCL can help to raise public awareness about counterfeit and illegal medicines. In Germany, the risk of counterfeit medicines reaching patients through the legal supply chain is still low, but the possibility cannot be ignored.

To-day, the computer-assisted 3D-technologies for the mathematical simulation of the engineering facilities are extensively used for the purpose of technical calculations in all branches of industry and building. The positive experience gained with the application of the 3D-models finds wide application in the joined investigations on the topical problems of the prosthetic and surgical treatment of bones, teeth, joints, cardiac valves, blood vessels, etc. The objective of the present study was the analysis of the positive experience with the involvement of the specialists in the design and practical application of 3D-models for the solution of problems facing the medical prosthetics and the management of various pathological conditions. Another objective was to discuss the possible prospects for the interdisciplinary collaboration in these fields with a view to improving the quality of expert conclusions in the framework of forensic medical and criminalistics examinations. The data readily available from the official domestic and foreign Internet resources were used for the purpose of the study. The analysis of the published data has demonstrated the obvious advantages of the application of the mathematical 3D-models and the biomechanical studies for the solution of the concrete medico-biological problems. The currently available positive experience gained due to the participation of domestic specialists in biomechanics in the solution of the specific clinical problems gives hope that their collaboration between themselves and with the forensic medical experts will open up the promising prospects for the further investigations of the issues of common interest.

In any civilization, nature is closely bound to the world of divinities. This is clearly seen in the Mediterranean world of Antiquity in every reference to the medicinal plants. Our aim, in this study, was to demonstrate the link between mythology and medicine. Through several centuries of medicinal practice, appears a therapeutic knowledge close to become a science. In spite of many gaps, errors and illusions thus emerges a first attempt to master the art of healing. Is it possible to speculate on a new type of drug research guided from ancient texts? Ethnopharmacology investigating medicinal traditions of the world has already obtained in this field some spectacular findings. At the moment, it would be difficult to predict the future of archeopharmacology but as Paul Valery said: "Present is nothing else than a future nutriment for the past".

The passage between theurgical to secular rational medicine in the ancient Greece is due to the naturalistic philosophers of the Ionia and the Hippocratic school, between 5th-4th century. However, we have a testimony that both theurgical and rational medicine coexisted in the temples of healing deified gods of medicine, i.e. Asklepion, Amphiaraos, etc. In fact, inscriptions, lat. sanationes, found in few Asklepíeia, i.e. Epidaurus, Lebena, Rome Tiberina Island, show clinical cases solved by the god. The dream is the bridge between the sick persons and the healer god, who acts during the incubation (incubatio) of semisleeping patients in a forbidden room (the [Greek]), near the temple. On the other hand, the dream in the Hippocratic medicine is useful for diagnostic purpose, other than for therapy. An extraordinary case of therapy for psychoneurotic diseases, such as melancholy or hypochondria, was the example of Aelius Aristides, who described his twelve-year experience of dreams related to Asklepiós in the Asklepieion of Pergamon.
Full text: Nuclear medicine occupies an important niche in the spectrum of medical capability. Since its initial application on a routine basis over 30 years ago its importance has continued to grow. For example, it is expected that over 430,000 Australians will have a nuclear medicine procedure in 1998. Current procedures using nuclear medicine are mainly concerned with diagnosis of oncology, cardiology and neurology. The main radioisotope used in nuclear medicine is Tc 99m, which is produced by a 'so called' Mo-Tc 99m generator. Other isotopes which currently find routine use are Ga-67, Th-201 and I-131. The selective uptakes by particular organs or structures is facilitated by the use of 'cold kits' which after the chemistry of the radioisotope many of the recent advances have been concerned with increasing the selectivity for a particular organ structure. Several of these new agents show increased selectivity using antibody a peptide recognition units

Is it ethical to market complementary and alternative medicines? Complementary and alternative medicines (CAM) are medical products and services outside the mainstream of medical practice. But they are not just medicines (or supposed medicines) offered and provided for the prevention and treatment of illness. They are also products and services - things offered for sale in the marketplace. Most discussion of the ethics of CAM has focused on bioethical issues - issues having to do with therapeutic value, and the relationship between patients and those purveyors of CAM. This article aims instead to consider CAM from the perspective of commercial ethics. That is, we consider the ethics not of prescribing or administering CAM (activities most closely associated with health professionals) but the ethics of selling CAM. © 2016 John Wiley & Sons Ltd.
What is the point of teaching the history of medicine? Many historians and clinicians find it regrettable that some medical students today will graduate knowing almost nothing of such "greats" of the past as Hippocrates, Galen, Vesalius, Harvey, Lister, and Pasteur. But does this really matter? After all, traditional history of medicine curricula tended to distort medicine's past, omitting the countless errors, wrong turns, fads, blunders, and abuses, in order to tell the sanitized stories of a few scientific superheroes. Modern scholarship has seriously challenged most of these heroic dramas; few of our heroes were as farsighted, noble, or obviously correct as once thought. Joseph Lister, for example, turns out to have had filthy wards, whereas William Harvey was devoted to the Aristotelianism he was long said to have overthrown . But as the history of medicine has become less romanticized, it has also become much more relevant, for it promises to impart useful lessons in the vital importance of scientific scepticism.

The Inga maintains alive a medical tradition whose therapeutics is based on the use of plants. There is evidence that they have incorporated into their medicine Hispanic medical principles and of other indigenous communities as well as the use of plants from other regions of Colombia, mainly by exchange with communities of the Amazonian jungle.119 plants used by Inga women specialists in medicine are referenced as well as the preparation of 149 remedies used to solve health problems
Theme of the 43rd Annual Conference of the Society of Nuclear Medicine India is 'empowering modem medicine with molecular nuclear medicine'. Keeping the theme in mind, the scientific committee has arranged an attractive and comprehensive program for both physicians and scientists reflecting the multimodality background of Nuclear Medicine and Metabolic Imaging. During this meeting the present status and future prospects of Nuclear medicine are discussed at length by esteemed faculty in dedicated symposia and interesting featured sessions which are immensely facilitate in educating the participants. Nuclear Medicine has come a long way since the first applications of radioiodine in the diagnosis of thyroid disease. The specialty of nuclear medicine in India is growing very rapidly. Technology continues to push the field in new directions and open new pathways for providing optimal care to patients. It is indeed an exciting time in the world of imaging and in the field of nuclear medicine. Innovative techniques in hardware and software offer advantages for enhanced accuracy. New imaging agents, equipment, and software will provide us with new opportunities to improve current practices and to introduce new technology into the clinical protocols. Papers relevant to INIS are indexed separately
Anthropology and medicine share many concerns, but have had trouble collaborating in the past. The anthropologist has had to plead both with his colleagues and physicians to move beyond a vision that would confine him to the study of traditional or alternative medicines and representations of populations and the sick. The anthropologist's approach perceived as intrusive has also raised fears in the medical world. These reciprocal misunderstandings and stereotypes need to be overcome by an anthropology that studies the practices and knowledge of modern medicine as they are elaborated daily. Anthropology will dialogue with medicine without judging it. In its turn, medicine will open its sites of healing and teaching to the anthropologist. Anthropology at the heart of medicine is organized around the idea that the paths and expectations of health professionals reflect the specicifities of the local system of health. The individual dimensions of practices cannot be divorced from the functioning of structures of health and decision. Finally, like any other kind of anthropology, medical anthropology must scrutinize its own methods and ethics in a critical way.

After a survey of the actual situation of nuclear medicine in Belgium, the evolution of nuclear medicine is studied with regard to quantitative aspects (tracerquantities, number of radioisotopic explorations, number of certified doctors) and qualitative aspects (use of short living isotopes emitting low energy radiation, introduction of in vitro tests). Taking these data into consideration, the exposure of nuclear medicine staff by external or internal radiation is evaluated. From this study it appears that the radiation exposure of the personnel of nuclear medicine departments remains low if proper manipulation methods and simple protective devices are used and if there is an efficient collaboration with an active health physics department or radiation control organism.

In Germany, alternative medicine is presently very popular and is supported by the federal government. When deliberating on the essence of alternative medicine we should simultaneously reflect on the intellectual and moral basis of regular medicine. To provide an epistemological demarcation of the 2 fields, the following 12 theses are advanced: (1) alternative and regular medicine are speaking different languages; (2) alternative medicine is not unconventional medicine; (3) the paradigm of regular medicine is rational thinking; (4) the paradigm of alternative medicine is irrational thinking; (5) the present popularity of alternative medicine can be explained by romanticism; (6) some concepts of alternative medicine are falsifiable and others are not; (7) alternative medicine and evidence-based medicine are mutually exclusive; (8) the placebo effect is an important factor in regular medicine and the exclusive therapeutic principle of alternative medicine; (9) regular and alternative medicine have different aims: coming of age vs faithfulness; (10) alternative medicine is not always safe; (11) alternative medicine is not economic; and (12) alternative medicine will always exist. The fact that alternative methods are presently an integral part of medicine as taught at German universities, as well as of the physician's fee schedule, represents a collective aberration of mind that hopefully will last for only a short time.

The performances of three clinical computed radiography (CR) systems (Agfa CR 75 (with CRMD 4. 0 image plates), Kodak CR 850 (with Kodak GP plates) and Kodak CR 850A (with Kodak GP plates) were evaluated using six tests recommended in American Association of Physicists in Medicine Report 93. The results indicated variable performances with majority being within acceptable limits. The variations were mainly attributed to differences in detector formulations, plate readers' characteristics, and aging effects. The differences of the mean low contrast scores between the imaging systems for three observers were statistically significant for Agfa and Kodak CR 850A (P=0.009) and for Kodak CR systems (P=0.006) probably because of the differences in ages. However, the differences were not statistically significant between Agfa and Kodak CR 850 (P=0.284) suggesting similar perceived image quality. The study demonstrates the need to implement quality control program regularly. (author)

Introduction : The advancement of precision medicine into routine clinical practice has been highlighted as an agenda for national and international health care policy. A principle barrier to this advancement is in meeting requirements of the payer or reimbursement agency for health care. This special report aims to explain the economic case for precision medicine, by accounting for the explicit objectives defined by decision-makers responsible for the allocation of limited health care resources. Areas covered : The framework of cost-effectiveness analysis, a method of economic evaluation, is used to describe how precision medicine can, in theory, exploit identifiable patient-level heterogeneity to improve population health outcomes and the relative cost-effectiveness of health care. Four case studies are used to illustrate potential challenges when demonstrating the economic case for a precision medicine in practice. Expert commentary : The economic case for a precision medicine should be considered at an early stage during its research and development phase. Clinical and economic evidence can be generated iteratively and should be in alignment with the objectives and requirements of decision-makers. Programmes of further research, to demonstrate the economic case of a precision medicine, can be prioritized by the extent that they reduce the uncertainty expressed by decision-makers.

The second congress of World Federation of Nuclear Medicine and Biology proved that nuclear medicine is returning to physiology. Around 1951, when motorized detector was introduced and when GM tube was replaced by scintillation crystal detector, physiologic nuclear medicine moved to anatomic nuclear medicine. Since 1970, when research on cardiology developed, nuclear medicine has been returning to physiology. Since 1963 Kuhl has been doing research on quantitative tomography which develops to emission computerized tomography emphasizing the physiological aspects of medicine. The recent contribution of nuclear medicine to medical science is the concept that human body is a unity of dynamic structure consisting of millions of cubes moving physio-chemically. (RUW)

The medicines refrigerator is a common piece of equipment found in clinical areas. It is used to ensure specific medicines are safely stored within a narrow temperature range in line with manufacturers' instructions; this is usually between +2˚C and +8˚C, and ideally +5˚C. Drugs stored in the medicines refrigerator include: vaccines; insulin; chemotherapy drugs; topical preparations, such as some types of eye drops; and other treatments such as glucagon, which is used to manage severe hypoglycaemia. This article reviews the function of the medicines refrigerator and the checks required by healthcare practitioners to ensure that medicines remain safely stored and their effectiveness is maintained. It also outlines the medicines refrigeration procedure known as the 'cold chain', which includes the use of cold boxes or vaccine carriers to maintain the required temperature of medicines during transport from the manufacturer to user, or between healthcare departments. ©2012 RCN Publishing Company Ltd.

This paper analyzes the influence of forensic medicine on therapeutic medicine through a case study of Qian Xiuchang and Hu Tingguang, two Chinese doctors who specialized in treating traumatic injuries. During the early nineteenth century, both men compiled medical treatises that sought to improve on a scholarly model of "rectifying bones" articulated in 1742 by the Imperially-Compiled Golden Mirror of the Medical Lineage . Both texts also incorporated information from forensic medicine, including official inquest diagrams and checklists promulgated by the Qing government. I show that they drew on these forensic materials to help address two interlinked medical issues: understanding the effects of injury on different parts of the body, and clarifying the location and form of the body's bones. Overall, I suggest that the exchange of ideas between the realm of therapeutic medicine and forensic medicine was an important epistemological strategy that doctors and officials alike employed to improve their knowledge of the material body.

Full Text Available People share medicines and problems can result from this behavior. Successful interventions to change sharing behavior will require understanding people's motives and purposes for sharing medicines. Better information about how medicines fit into the gifting and reciprocity system could be useful in designing interventions to modify medicine sharing behavior. However, it is uncertain how people situate medicines among other items that might be shared. This investigation is a descriptive study of how people sort medicines and other shareable items.This study in the Dominican Republic examined how a convenience sample (31 people sorted medicines and rated their shareability in relation to other common household items. We used non-metric multidimensional scaling to produce association maps in which the distances between items offer a visual representation of the collective opinion of the participants regarding the relationships among the items. In addition, from a pile sort constrained by four categories of whether sharing or loaning the item was acceptable (on a scale from not shareable to very shareable, we assessed the degree to which the participants rated the medicines as shareable compared to other items. Participants consistently grouped medicines together in all pile sort activities; yet, medicines were mixed with other items when rated by their candidacy to be shared. Compared to the other items, participants had more variability of opinion as to whether medicines should be shared.People think of medicines as a distinct group, suggesting that interventions might be designed to apply to medicines as a group. People's differing opinions as to whether it was appropriate to share medicines imply a degree of uncertainty or ambiguity that health promotion interventions might exploit to alter attitudes and behaviors. These findings have implications for the design of health promotion interventions to impact medicine sharing behavior.
Nuclear medicine provides an opportunity to image pathophysiology, while radiology mainly shows morphology. Over the last few decades hybrid imaging modalities have been developed in which nuclear medicine instrumentation has been combined with computed tomography (CT) and, more recently, with magnetic ...
The last developments in medical imaging allow visualization of medicines in organism. Today, these techniques: positron emission tomography (PET) and single photon emission computed tomography (SPECT) play an essential role in the production and the development of new medicines. The medicinal substances labelled with radioisotopes permit to improve the understanding of medicines' action mode. The spectacular advances were observed in the field of medicines acting on the brain (F.M.)
There is a well-known quotation by the nineteenth-century sociologist Virchow (quoted in Ref. 1) that aptly captures the dilemma that has confronted public health medicine since the specialty was created as a discrete entity in 1848. Virchow said: 'Medicine is politics and social medicine is politics writ large!' What does this mean in relation to effective public health medicine practice and how is it likely to affect its future? There is increasingly limited freedom of expression within the current context of political correctness, central control and a rapidly burgeoning litigious climate. The purpose of this paper is to explore these issues and to propose a means of maintaining public health medicine integrity within a working environment where action is becoming rapidly constrained by political rigidity. An additional factor to be included in the dialogue is the current context within which public health physicians work. Because the majority of public health doctors are employed within the National Health Service (NHS), they are finding themselves being expected to take on tasks and responsibilities marginal to their essential purpose and function. For example, public health physicians spend a great deal of time involved in detailed deliberations about health service provision. Although there is a great deal of evidence to show that good quality health care provision positively affects the health of the individual, there is no evidence to show that this activity has any effect on the population's health status. The essence of public health medicine practice is the prevention of ill-health and the promotion of the health of the population and, consequently, attention needs to be focused on the root causes of disease. However, as these are outside the aegis of the NHS, public health medicine involvement in such issues as education, nutrition, housing, transport and poverty is regarded as marginal to the NHS corporate agenda.

Talensi materia medica is varied, encompassing plant, mineral, and animal substances. Healing, medicines, and medicinal practices and knowledge can be shrine-based and linked with ritual practices. This is explored utilising ethnographic data and from an archaeological perspective with reference to future possibilities for research both on Talensi medicine and, by implication, more generally through considering the archaeology of Talensi medicine preparation, use, storage, spread, and disposal. It is suggested that configuring the archaeology of medicine shrines and practices more broadly in terms of health would increase archaeological visibility and research potential.

Purpose: Four-dimensional computed tomography (4DCT) ventilation imaging provides lung function information for lung cancer patients undergoing radiation therapy. Before 4DCT-ventilation can be implemented clinically it needs to be validated against an established imaging modality. The purpose of this work was to compare 4DCT-ventilation to nuclear medicine ventilation, using clinically relevant global metrics and radiologist observations. Methods and Materials: Fifteen lung cancer patients with 16 sets of 4DCT and nuclear medicine ventilation-perfusion (VQ) images were used for the study. The VQ-ventilation images were acquired in planar mode using Tc-99m-labeled diethylenetriamine-pentaacetic acid aerosol inhalation. 4DCT data, spatial registration, and a density-change-based model were used to compute a 4DCT-based ventilation map for each patient. The percent ventilation was calculated in each lung and each lung third for both the 4DCT and VQ-ventilation scans. A nuclear medicine radiologist assessed the VQ and 4DCT scans for the presence of ventilation defects. The VQ and 4DCT-based images were compared using regional percent ventilation and radiologist clinical observations. Results: Individual patient examples demonstrate good qualitative agreement between the 4DCT and VQ-ventilation scans. The correlation coefficients were 0.68 and 0.45, using the percent ventilation in each individual lung and lung third, respectively. Using radiologist-noted presence of ventilation defects and receiver operating characteristic analysis, the sensitivity, specificity, and accuracy of the 4DCT-ventilation were 90%, 64%, and 81%, respectively. Conclusions: The current work compared 4DCT with VQ-based ventilation using clinically relevant global metrics and radiologist observations. We found good agreement between the radiologist's assessment of the 4DCT and VQ-ventilation images as well as the percent ventilation in each lung. The agreement lessened when the data were

Community diagnosis and approach has shifted from a professional focus to a community focus. The information system has also been developed to reflect socio-cultural information. This new system has been established throughout the country and is being recorded in the computer system. However these data still lack human capital information to promote community mobilization. The present study aims to develop a process which reflects human capital from the insider and outsider points of view and which builds on the existing work system of primary care service, family medicine, and community medicine. The present study applies the participatory action research design with mixed methods including community grand-tour, household survey socio-metric questionnaire and focus group discussion in order to gather insider view of human capital. A key instrument developed in the present study is the socio-metric questionnaire which was designed according to the community grand tour and household survey results. The findings indicate that the process is feasible and the insider point of view given a longer evidence based list of the human capital. The model enhanced a closer relationship between professional and community people and suggested the realistic community mobilizer name list. Human capital identification process is feasible and should be recommended to integrate in the existing work process of the health staff in family and community practice.

The study of literature and conducted field experiments revealed the presence of 41 species of medicinal plants of the celery family (Apiaceae Lindl., among which 11 cultivated species. There was a brief description of botanical species studied, the typical place of growth, and the presence of biologically active compounds that determine the medicinal properties of the studied taxons. The studied plants have various quantitative and spatial relationship: 6 species are rare and are considered as protected plants, 2 species does not grow in Luhansk, 3 — in the Donetsk region, 4 species are considered to be adventitious for our region. Medicinal plants of the family celery cover a wide range of various diseases due to the large number of various biologically active substances and, primarily, essential fatty oils, flavonoids, vitamins and coumarins. It is worth noting that there no agricultural enterprises specialized on medicinal plants cultivating.
Full Text Available The paper explores some of the issues concerning the transmission of Chinese medicine in Australia, its practitioner training and the future of Chinese medicine as a distinct medical discipline in the Australian context. In China over the last century Chinese medicine was overhauled in order to align it with the biomedical perspective prevalent in the West. These changes, in turn, had important consequences for the transmission of CM in Australia and the West. But while the biomedicalisation of CM has offered the path of least resistance, it has also lead to unworkable simplifications and methodological failures. The paper thus argues for a renewed access to the tradition’s primary sources in order to ally the distinctive features and methods of traditional practice with biomedicine, as an alternative to an outright integration into biomedical practice.

Pheno-/endotyping chronic obstructive pulmonary disease (COPD) is really important because it provides patients with precise and personalized medicine. The central concept of precision medicine is to take individual variability into account when making management decisions. Precision medicine should ensure that patients get the right treatment at the right dose at the right time, with minimum harmful consequences and maximum efficacy. Ideally, we should search for genetic and molecular biomarker-based profiles. Given the clinical complexity of COPD, it seems likely that a panel of several biomarkers will be required to characterize pathogenetic factors and their course over time. The need for biomarkers to guide the clinical care of individuals with COPD and to enhance the possibilities of success in drug development is clear and urgent, but biomarker development is tremendously challenging and expensive, and translation of research efforts to date has been largely ineffective. Furthermore, the development of personalized treatments will require a much more detailed understanding of the clinical and biological heterogeneity of COPD. Therefore, we are still far from being able to apply precision medicine in COPD and the treatable traits and FEV 1 -free approaches are attempts to precision medicine in COPD that must be considered still quite unsophisticated.
Full Text Available The miniaturization and virtualization processes drive converging technologies from interactions between the NBIC (Nano, Bio, Info, and Cogno technologies. The converging technologies stimulate innovation, promote research and development in different fields and produce revolutionary progresses in medicine. These technologies enable us to create contacts between brains and machines, the growth in molecular nanotechnology, the construction of respirocytes, chromallocytes, clottocytes, nanorobotic phagocytes, and nanobots. Nanobots would enter the nucleus of a cell and extract all of the genetic material and replace it with a synthetically produced copy of the original that has been manufactured in a laboratory to contain only non-defective base-pairs. It is predicted that “the regenerative medicine”, as a megatrend, will have an enormous effect on medical technologies and clinical sciences. Regenerative medicine is an application field of converging technologies in translational medicine. It attempts to translate the results of tissue engineering to construct 3D tissues and organs. Regenerative medicine is also an exciting field for induced pluripotent stem cell (iPSC and promises to bring about a paradigm shift to health care. Accumulating evidence indicates that converging technologies will offer great potentials for regenerative medicine to create innovative treatments for diseases that the traditional therapies have not been effective yet.

Physician workforce projections by the Institute of Medicine require enhanced training in geriatrics for all primary care and subspecialty physicians. Defining essential geriatrics competencies for internal medicine and family medicine residents would improve training for primary care and subspecialty physicians. The objectives of this study were to (1) define essential geriatrics competencies common to internal medicine and family medicine residents that build on established national geriatrics competencies for medical students, are feasible within current residency programs, are assessable, and address the Accreditation Council for Graduate Medical Education competencies; and (2) involve key stakeholder organizations in their development and implementation. Initial candidate competencies were defined through small group meetings and a survey of more than 100 experts, followed by detailed item review by 26 program directors and residency clinical educators from key professional organizations. Throughout, an 8-member working group made revisions to maintain consistency and compatibility among the competencies. Support and participation by key stakeholder organizations were secured throughout the project. The process identified 26 competencies in 7 domains: Medication Management; Cognitive, Affective, and Behavioral Health; Complex or Chronic Illness(es) in Older Adults; Palliative and End-of-Life Care; Hospital Patient Safety; Transitions of Care; and Ambulatory Care. The competencies map directly onto the medical student geriatric competencies and the 6 Accreditation Council for Graduate Medical Education Competencies. Through a consensus-building process that included leadership and members of key stakeholder organizations, a concise set of essential geriatrics competencies for internal medicine and family medicine residencies has been developed. These competencies are well aligned with concerns for residency training raised in a recent Medicare Payment Advisory

The origins and advancements of pharmacy, medicinal chemistry, and drug discovery are interwoven in nature. Medicinal chemistry provides pharmacy students with a thorough understanding of drug mechanisms of action, structure-activity relationships (SAR), acid-base and physicochemical properties, and absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiles. A comprehensive understanding of the chemical basis of drug action equips pharmacy students with the ability to answer rationally the "why" and "how" questions related to drug action and it sets the pharmacist apart as the chemical expert among health care professionals. By imparting an exclusive knowledge base, medicinal chemistry plays a vital role in providing critical thinking and evidence-based problem-solving skills to pharmacy students, enabling them to make optimal patient-specific therapeutic decisions. This review highlights the parallel nature of the history of pharmacy and medicinal chemistry, as well as the key elements of medicinal chemistry and drug discovery that make it an indispensable component of the pharmacy curriculum.

Due to negligence, Persian (Iranian) traditional medicine has had a weak presence in the world of research for a long time. However, in recent years, a variety of activates by research and faculty centers have created awareness and a platform to introduce and promote Persian medicine to the world. The aim of this study is to present and analyze scientific achievements of Persian medicine in the world of research. Articles were collected from PubMed database using keywords such as "Persian medicine", "Persian traditional medicine", "Iranian medicine", and "Iranian traditional medicine". All data were classified based on the type of research (review, intervention, case reports, etc.), the field of study (neurology, cardiovascular, metabolic, historical studies, etc.), publication year, and journal type. A total of 501 articles were identified until the end of 2015, comprising of 222 reviews and 219 interventional (108 animal, 57 clinical and 54 cellular). Most studies were on neurology (20.1%), gastroenterology (14.5%), and cardiovascular diseases (10.4%). The publications in 2015 and 2014 had the highest hit rate with 139 and 132 articles, respectively, with 1:2 publication ratio between foreign and Iranian journals. The most published articles, both foreign and Iranian, were in "Evidence-Based Complementary and Alternative Medicine" and "Iranian Red Crescent Medicine" journals. The contribution of foreign authors was 5%. The primary focus of the articles was on "Basic concepts of Persian medicine", "Healthy lifestyle according to Persian medicine", and "Historical aspects", by 3.1%, 2.9%, and 6.7%, respectively. During the last 2 years, the number of articles published in Persian (Iranian) medicine, particularly clinical studies had significant growth in comparison with the years before. The tendency of foreign researchers to use the keywords "Iranian" or "Persian" medicine is notable. This research was only based on the designated keyword and other keywords were
Ionizing radiation is firmly established as an essential tool for diagnosis and therapy in medicine, although patterns of use vary widely around the world. Diagnostic examinations are conducted mainly with X rays (diagnostic radiology) and less commonly by administering radiopharmaceuticals to patients (nuclear medicine). Radiotherapy is mostly carried out using external beams of radiation (teletherapy), although some patients receive direct applications of sealed radionuclide sources (brachytherapy) or therapeutic administrations of radiopharmaceuticals. Global data from the United Nations Scientific Committee on the Effects of Atomic Radiation indicate an annual total of about 2500 million diagnostic radiological examinations in 1996: 78% involving medical X rays (at a mean rate of 330 per 1000 world population), 21% involving dental X rays (mean rate 90 per 1000) and only 1% involving nuclear medicine (mean rate 5.6 per 1000). Over 90% of the estimated annual total of about 5.5 million complete courses of radiation treatment are conducted by teletherapy or brachytherapy, with mean rates of 0.8 and 0.07 per 1000 world population, respectively; radiopharmaceuticals are used in only 7% of all treatments (mean rate 0.065 per 1000). Over three quarters of all diagnostic procedures and over half of all treatments occur in developed countries, which collectively represent only one quarter of the world population. The general global trend is for increasing numbers of procedures. The paper discusses the current uses of radiation in medicine, including diagnostic radiology, diagnostic nuclear medicine and radiotherapy. (author)

Full Text Available To understand the traditional description of medicine as a practice of healing, it is necessary to examine its relationships with both science and ethics. The “scientific” component of medicine includes an acknowledgment of the influence of social, cultural and environmental factors on the functioning of the organism. The “ethical” component is often presented as merely supplementary but actually provides the conditions of possibility of knowledge. “Healing” then appears as what joins the two together: the site where science is applied in the service of ethics and where ethics encounters science. This perspective allows us to reconsider medicine as a project to healing complex wounds that manifest themselves at the physical, psychological, emotional and cultural levels.

Although the paradigm of the 4P medicine - Predictive, Personalized, Preemptive, and Participatory - has been suggested several years ago, its application to atrial fibrillation is still far away. Given the increasing prevalence and incidence of this pathology it is the time to promote preventive strategies, by identifying the risk factors associated to life style and by incentivizing innovative diagnostic technologies. The promotion of the correct life style and of the use of diagnostic devices based on innovative and reliable technologies, represent a first step towards the full realization of the revolution of 4P medicine in atrial fibrillation.

After a brief review of the life and work of Paracelsus (1493-1541) the five spheres of existence of the healthy as well as the sick individual are characterized (theory of the 5 entities). Founding on this theoretical orientation of existence Paracelsus constructs his "house of medicine" which is resting on 4 pillars: on "Philosophia" as natural and human science, on "Astronomia" as structured chronologic order, on "Alchimia" as science of the preparation of materials and on "Physica" providing the ethical prerequisite for medical practise. Paracelsus believes the physician to represent an educated expert applying standards to the other faculties as well; in his eyes medicine represents the "cornerstone of university".
Modern medical care is influenced by two paradigms: 'evidence-based medicine' and 'patient-centered medicine'. In the last decade, both paradigms rapidly gained in popularity and are now both supposed to affect the process of clinical decision making during the daily practice of physicians. However,

The Influenza A virus is a great threat for human health, while various subtypes of the virus made it difficult to develop drugs. With the development of state-of-art computational chemistry, computational molecular docking could serve as a virtual screen of potential leading compound. In this study, we performed molecular docking for influenza A H1N1 (A/PR/8/34) with small molecules such as quercetin and chlorogenic acid, which were derived from traditional Chinese medicine. The results showed that these small molecules have strong binding abilities with neuraminidase from H1N1 (A/PR/8/34). Further details showed that the structural features of the molecules might be helpful for further drug design and development. The experiments in vitro, in vivo have validated the anti-influenza effect of quercetin and chlorogenic acid, which indicating comparable protection effects as zanamivir. Taken together, it was proposed that chlorogenic acid and quercetin could be employed as the effective lead compounds for anti-influenza A H1N1.

Medicinal cannabis is an invaluable adjunct therapy for pain relief, nausea, anorexia, and mood modification in cancer patients and is available as cookies or cakes, as sublingual drops, as a vaporized mist, or for smoking. However, as with every herb, various microorganisms are carried on its leaves and flowers which when inhaled could expose the user, in particular immunocompromised patients, to the risk of opportunistic lung infections, primarily from inhaled molds. The objective of this study was to identify the safest way of using medicinal cannabis in immunosuppressed patients by finding the optimal method of sterilization with minimal loss of activity of cannabis. We describe the results of culturing the cannabis herb, three methods of sterilization, and the measured loss of a main cannabinoid compound activity. Systematic sterilization of medicinal cannabis can eliminate the risk of fatal opportunistic infections associated with cannabis among patients at risk.

Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials to examine organ function and structure. Nuclear medicine is older than CT, ultrasound and MRI. It was first used in patients over 60-70 years ago. Today it is an established medical specialty and offers procedures that are essential in many medical specialities like nephrology, pediatrics, cardiology, psychiatry, endocrinology and oncology. Nuclear medicine refers to medicine (a pharmaceutical) that is attached to a small quantity of radioactive material (a radioisotope). This combination is called a radiopharmaceutical. There are many radiopharmaceuticals like DTPA, DMSA, HIDA, MIBI and MDP available to study different parts of the body like kidneys, heart and bones etc. Nuclear medicine uses radiation coming from inside a patient's body where as conventional radiology exposes patients to radiation from outside the body. Thus nuclear imaging study is a physiological imaging, whereas diagnostic radiology is anatomical imaging. It combines many different disciplines like chemistry, physics mathematics, computer technology, and medicine. It helps in diagnosis and to treat abnormalities very early in the progression of a disease. The information provides a quick and accurate diagnosis of wide range of conditions and diseases in a person of any age. These tests are painless and most scans expose patients to only minimal and safe amounts of radiation. The amount of radiation received from a nuclear medicine procedure is comparable to, or often many times less than, that of a diagnostic X-ray. Nuclear medicine provides an effective means of examining whether some tissues/organs are functioning properly. Therapy using nuclear medicine in an effective, safe and relatively inexpensive way of controlling and in some cases eliminating, conditions such as overactive thyroid, thyroid cancer and arthritis. Nuclear medicine imaging is unique because it provides doctors with

The history of beauty is as old as mankind itself--throughout history people have tried to improve their attractiveness and to enhance their beauty. The technical basis for many of nowadays procedures like lipoplasty, breast augmentation or rhinoplasty was thereby initiated more than a hundred years ago and evolved to the modern standards of today. The aim of this article is to recall the early days of aesthetic medicine and show the swift progress up to the highly specialized medical discipline of our modern time. Combining the past, present and future of aesthetic medicine, allows to incorporate this perspective and ultimately to delivery better patient care.

The dengue virus and related flaviviruses are an increasing global health threat. In this perspective, we comment on and review medicinal chemistry efforts aimed at the prevention or treatment of dengue infections. We include target-based approaches aimed at viral or host factors and results from phenotypic screenings in cellular assay systems for viral replication. This perspective is limited to the discussion of results that provide explicit chemistry or structure-activity relationship (SAR), or appear to be of particular interest to the medicinal chemist for other reasons. The discovery and development efforts discussed here may at least partially be extrapolated toward other emerging flaviviral infections, such as West Nile virus. Therefore, this perspective, although not aimed at flaviviruses in general, should also be able to provide an overview of the medicinal chemistry of these closely related infectious agents.

Traditional Indian medicine (ayurveda) is becoming increasingly popular, with many chronic conditions responding to it well. Most patients begin to take conventional medications as soon as their diagnoses are made, so ayurvedic treatments are usually undergone alongside and/or after conventional medical approaches. A detailed knowledge of the action of food, spices, and medicinal plants is needed in order to understand their potential influence fully. While societal use of ayurvedic plants and Indian spices is commonplace, without ill effect, the use of more concentrated products made from single plants, often in the form of teas or tablets, is of more concern. The mechanisms by which polyherbal drugs and their extracts act differ in many respects from the actions of single substances or synthetic drugs. Despite the fact that ayurvedic medicines are based on natural herbal materials, their safety depends on their method of administration, taking into account individuals’ needs and their specific disease conditions.

With the rapid development of technology, computation claims its irrevocable place among research components of modern science. Thus to foster a successful future scientist, engineer or educator we need to add computation to the foundations of scientific education. We will discuss what type of paradigm shifts it brings to these foundations on the example of Wolfram Science Summer School. It is one of the most advanced computational outreach programs run by Wolfram Foundation, welcoming participants of almost all ages and backgrounds. Centered on complexity science and physics, it also covers numerous adjacent and interdisciplinary fields such as finance, biology, medicine and even music. We will talk about educational and research experiences in this program during the 12 years of its existence. We will review statistics and outputs the program has produced. Among these are interactive electronic publications at the Wolfram Demonstrations Project and contributions to the computational knowledge engine Wolfram|Alpa.

Estimates of the risks of exposing an embryo or fetus to radiation are discussed. Recommendations are made about the policies a nuclear medicine department should develop for handling cases of accidental irradiation of an embryo or fetus. The choices available where a known pregnancy is involved and diagnostic radiology is required are outlined. Only necessary examinations should be performed and care taken to avoid or minimise irradiation of the fetus. The nuclear medicine physician must be prepared to make (and defend if necessary) an informed decision on whether to proceed with an examination and must also be in a position to discuss the risks with anxious parents

Acupuncture is covered under the Accident Compensation (Liability to Pay or Contribute to Cost of Treatment) Regulations 2003, and is therefore eligible for Accident Compensation Corporation payments for the treatment of personal injuries. This study searched New Zealand acupuncturists' websites for therapeutic claims that may breach Section 58(1)(a) of the Medicines Act. A search of acupuncturists' websites shows that many claim to be able to treat a wide range of conditions, despite a lack of evidence showing the efficacy of acupuncture in the treatment of those conditions. Practitioners and owners of websites likely to be in breach of the Medicines Act include many committee members from acupuncture's professional bodies.

The basic concept of integrative medicine (IM) is that by combining mainstream (biomedicine) with complementary and alternative medicine (CAM), synergistic therapeutic effects can be attained. When the methods of mind/body medicine (MBM) are added to this combination, as in Western countries, a new concept emerges that drastically changes the approach toward illness.It is interesting to note that the joining of traditional Chinese medicine and Western medicine in the early days of the Peoples' Republic of China preceded the Western model of IM by almost 50 years. Several elements that make up the key components of IM as practiced today in the West were already present in the Chinese version of IM, and Chinese medicine has played and continues to play an important role in advancing IM. However, one of the major differences between the Chinese and the Western models of IM today, besides MBM and some other treatment options, is that Western integrative medicine (WIM) strictly requires its CAM methods to be supported by scientific evidence.The therapeutic methods of IM and their applications are many and varied. However, they are most frequently employed to treat chronic medical conditions, e.g., bronchial asthma, rheumatic disease, chronic inflammatory bowel disorder and chronic pain. Other fields in which IM may be applied are internal medicine (inflammatory bowel diseases and cardiovascular diseases), musculoskeletal disorders, oncology (chemotherapy-induced side effects), obstetrics and gynecology (dysmenorrhea, endometriosis, infertility and menopausal complaints), pediatrics, geriatrics, neurology (migraine and chronic headache), and psychiatry (anxiety and depression).The concept of WIM is discussed here in detail by reviewing its scope and implications for the practice of medicine and focusing on the role of Chinese medicine in WIM.

Full Text Available Summary: Precision medicine strives to delineate disease using multiple data sources—from genomics to digital health metrics—in order to be more precise and accurate in our diagnoses, definitions, and treatments of disease subtypes. By defining disease at a deeper level, we can treat patients based on an understanding of the molecular underpinnings of their presentations, rather than grouping patients into broad categories with one-size-fits-all treatments. In this review, the authors examine how precision medicine, specifically that surrounding genetic testing and genetic therapeutics, has begun to make strides in both common and rare cardiovascular diseases in the clinic and the laboratory, and how these advances are beginning to enable us to more effectively define risk, diagnose disease, and deliver therapeutics for each individual patient.

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.

Precision medicine in oncology focuses on identifying which therapies are most effective for each patient based on genetic characterization of the cancer. Traditional chemotherapy is cytotoxic and destroys all cells that are rapidly dividing. The foundation of precision medicine is targeted therapies and selecting patients who will benefit most from these therapies. One of the newest aspects of precision medicine is liquid biopsy. A liquid biopsy includes analysis of circulating tumor cells, cell-free nucleic acid, or exosomes obtained from a peripheral blood draw. These can be studied individually or in combination and collected serially, providing real-time information as a patient's cancer changes. Copyright © 2016 Elsevier Inc. All rights reserved.

Oligonucleotide-based therapeutics have made rapid progress in the clinic for treatment of a variety of disease indications. Unmodified oligonucleotides are polyanionic macromolecules with poor drug-like properties. Over the past two decades, medicinal chemists have identified a number of chemical modification and conjugation strategies which can improve the nuclease stability, RNA-binding affinity, and pharmacokinetic properties of oligonucleotides for therapeutic applications. In this perspective, we present a summary of the most commonly used nucleobase, sugar and backbone modification, and conjugation strategies used in oligonucleotide medicinal chemistry.
Selection in reproductive medicine today relies on normative assessments of what ‘good life’ consists of. This paper explores the terms under which such assessments are made by focusing on three particular concepts of ‘quality’: quality of life, biological quality and population quality....... It is suggested that the apparently conflicting hypes, hopes and fears that surround reproductive medicine can co-circulate because of the different forms of normative assessment that these concepts allow. To ensure clarity in bioethical deliberations about selection, it is necessary to highlight how...
Background At postgraduate level evidence based medicine (EBM) is currently taught through tutor based lectures. Computer based sessions fit around doctors' workloads, and standardise the quality of educational provision. There have been no randomized controlled trials comparing computer based sessions with traditional lectures at postgraduate level within medicine. Methods This was a randomised controlled trial involving six postgraduate education centres in the West Midlands, U.K. Fifty five newly qualified foundation year one doctors (U.S internship equivalent) were randomised to either computer based sessions or an equivalent lecture in EBM and systematic reviews. The change from pre to post-intervention score was measured using a validated questionnaire assessing knowledge (primary outcome) and attitudes (secondary outcome). Results Both groups were similar at baseline. Participants' improvement in knowledge in the computer based group was equivalent to the lecture based group (gain in score: 2.1 [S.D = 2.0] versus 1.9 [S.D = 2.4]; ANCOVA p = 0.078). Attitudinal gains were similar in both groups. Conclusion On the basis of our findings we feel computer based teaching and learning is as effective as typical lecture based teaching sessions for educating postgraduates in EBM and systematic reviews.

The most common cognitive disorder that is disabling is dementia. During the medieval period, traditional Persian medicine was an outstanding source of medicine that was used as standard references in medical schools of in the West and Middle East. In ancient manuscripts of traditional Persian medicine, a condition has been introduced similar to dementi (raoonat and homgh). In this article, by collecting materials of traditional medicine texts on dementia, we aim to provide theories for further studies on this topics, as there is an obvious difference between traditional Persian medicine and modern medicine with regard to dementia; however, since modern medicine has not found a suitable response to treatment for all diseases, reviewing traditional Persian medicine for finding better treatment strategies is wise. Use of all medical potentials approved by the World Health Organization beside classic medicine like traditional medicine and considering the availability and acceptability among people is recommended. © The Author(s) 2015.

The use of fragment-based drug discovery (FBDD) has increased in the last decade due to the encouraging results obtained to date. In this scenario, computational approaches, together with experimental information, play an important role to guide and speed up the process. By default, FBDD is generally considered as a constructive approach. However, such additive behavior is not always present, therefore, simple fragment maturation will not always deliver the expected results. In this review, computational approaches utilized in FBDD are reported together with real case studies, where applicability domains are exemplified, in order to analyze them, and then, maximize their performance and reliability. Thus, a proper use of these computational tools can minimize misleading conclusions, keeping the credit on FBDD strategy, as well as achieve higher impact in the drug-discovery process. FBDD goes one step beyond a simple constructive approach. A broad set of computational tools: docking, R group quantitative structure-activity relationship, fragmentation tools, fragments management tools, patents analysis and fragment-hopping, for example, can be utilized in FBDD, providing a clear positive impact if they are utilized in the proper scenario - what, how and when. An initial assessment of additive/non-additive behavior is a critical point to define the most convenient approach for fragments elaboration.
Physics is a fundamental science that finds its applications in all areas of our lives. Its application in modern medicine is undeniable. In today’s medical practice special attention is dedicated to the use of ionizing radiation. The wide range of modern science and technology offers enormous possibilities for creation and implementation of new equipment using adequate doses of ionizing radiation. For accurate medical diagnostics and effective treatment of patients, this type of equipment must provide the necessary information to the physicians. On the other hand, the physicians should possess enough knowledge in the relative field of medicine. This paper contains information about the knowledge communicated to the students of the graduate program Medical Physics and Biophysics in the discipline Medicine in the first year of graduate study at the Medical University “Prof. Dr. Paraskev Stoyanov” of Varna. Firstly, we discuss the topics in the lectures of these two disciplines, concerning knowledge about ionizing radiation. Secondly, the respective laboratory exercises are described that illustrate the lectures in the graduate programs Medical Physics and Biophysics.

Interest in alternative medicine is growing among healthcare consumers. Health plans and healthcare organizations may be able to improve clinical outcomes and benefit financially by providing patients with access to alternative services. Organizations that can assess their communities' particular needs, draw on interested professional staff to help develop alternative medicine programs and protocols, and study quality outcomes will stand a better chance of making such programs successful. Educating medical staff, designing a credible program, and forging strategic alliances with respected partners can help organizations create a sharply focused brand identity in the community.

Alternative medicine (AM) is of growing interest to the general public. Although several studies have been published concerning its use in adults, the use by children is less well known. The purpose of this study is to determine the frequency with which alternative medicine is employed in a pediatric population that also uses conventional medicine. A second goal is to investigate the sociodemographic factors that influence the choice of these forms of therapy. Parents of children consulting the general outpatient clinic of a university hospital completed a self-administered questionnaire asking about previous use of AM for themselves or their children. Based on 1911 completed questionnaires, 208 children (11%) previously consulted one or more AM practitioners. Chiropractic, homeopathy, naturopathy, and acupuncture together accounted for 84% of use. Children who used AM differed significantly from those who only used conventional medicine in that they were older than the nonusers, their mothers were better educated, and their parents also tended to use AM. The findings indicate that AM is an aspect of child health care that no longer can be ignored. Being aware of these practices will enable physicians to discuss alternative therapies with parents in order to ensure the continuity of essential conventional treatments.

Once considered exclusively the cell's powerhouse, mitochondria are now recognized to perform multiple essential cellular functions beyond energy production, impacting most areas of cell biology and medicine. Since the emergence of molecular biology and the discovery of pathogenic mitochondrial DNA defects in the 1980's, research advances have revealed a number of common human diseases which share an underlying pathogenesis involving mitochondrial dysfunction. Mitochondria undergo function-defining dynamic shape changes, communicate with each other, regulate gene expression within the nucleus, modulate synaptic transmission within the brain, release molecules that contribute to oncogenic transformation and trigger inflammatory responses systemically, and influence the regulation of complex physiological systems. Novel “mitopathogenic” mechanisms are thus being uncovered across a number of medical disciplines including genetics, oncology, neurology, immunology, and critical care medicine. Increasing knowledge of the bioenergetic aspects of human disease has provided new opportunities for diagnosis, therapy, prevention, and in connecting various domains of medicine. In this article, we overview specific aspects of mitochondrial biology that have contributed to – and likely will continue to enhance the progress of modern medicine. PMID:27423788
Matched molecular pairs (MMPs) are widely used in medicinal chemistry to study changes in compound properties including biological activity, which are associated with well-defined structural modifications. Herein we describe up-to-date versions of three MMP-based data sets that have originated from in-house research projects. These data sets include activity cliffs, structure-activity relationship (SAR) transfer series, and second generation MMPs based upon retrosynthetic rules. The data sets have in common that they have been derived from compounds included in the ChEMBL database (release 17) for which high-confidence activity data are available. Thus, the activity data associated with MMP-based activity cliffs, SAR transfer series, and retrosynthetic MMPs cover the entire spectrum of current pharmaceutical targets. Our data sets are made freely available to the scientific community. PMID:24627802

In this paper, a recently developed computer-based dental implant positioning system with an image-to-tissue interface is presented. On a computer monitor or in a head-up display, planned implant positions and the implant drill are graphically superimposed on the patient's anatomy. Electromagnetic 3D sensors track all skull and jaw movements; their signal feedback to the workstation induces permanent real-time updating of the virtual graphics' position. An experimental study and a clinical case demonstrates the concept of the augmented reality environment - the physician can see the operating field and superimposed virtual structures, such as dental implants and surgical instruments, without loosing visual control of the operating field. Therefore, the operation system allows visualization of CT planned implantposition and the implementation of important anatomical structures. The presented method for the first time links preoperatively acquired radiologic data, planned implant location and intraoperative navigation assistance for orthotopic positioning of dental implants.

The method of computer tomography (CT) was applied for neutrons instead of X-rays. The neutron radiography image of samples was scanned by microphotometer to get the transmission data. This process was so time-consuming that the number of incident angles to samples could not be increased. The transmission data was processed by FACOM computer and CT image was gained. In the experiment at the Japan Research Reactor No. 4 at Tokai-mura with 18 projection angles, the resolution of paraffin in the aluminum block was less than 0.8 mm. In the experiment at Van de Graaf accelerator of Nagoya University, this same resolution was 1.2 mm because of the angle distribution of neutron beam. This experiment is the preliminary one, the facility which utilizes neutron television and video-recorder will be necessary for the next stage. (Auth.)

To explore advantages of Chinese medicine (CM) by analyzing differences in the origin of philosophy for human health between CM and Western medicine (WM). Methodologically, a distinctive feature of CM is its systems theory, which is also the difference between CM and WM. Since the birth of CM, it has taken the human body as a whole from the key concepts of "qi, blood, yin-yang, viscera (Zang-Fu), and meridian and channel", rather than a single cell or a particular organ. WM evolves from the Western philosophic way of thinking and merely uses natural sciences as the foundation. The development of WM is based on human structures, or anatomy, and therefore, research of WM is also based on the way of thinking of decomposing the whole human body into several independent parts, which is the impetus of promoting the development of WM. The core of CM includes the holistic view and the dialectical view. Chinese herbal medicines contain various components and treat a disease from multiple targets and links. Therefore, Chinese herbal medicines treat a diseased state by regulating and mobilizing the whole body rather than just regulating a single factor, since the diseased state is not only a problem in a local part of the body but a local reflection of imbalance of the whole body.

Substantially, plants produce chemicals such as primary and secondary metabolites, which have significant applications in modern therapy. Indigenous people mostly rely on traditional medicines derived from medicinal plants. These plants have the capacity to absorb a variety of toxic elements. The ingestion of such plants for medicinal purpose can have imperative side effects. Hence, with regard to the toxicological consideration of medicinal plants, an effort has been made to review the elemental contents of ethno medicinally important plants of Pakistan and to highlight the existing gaps in knowledge of the safety and efficacy of traditional herbal medications. Literature related to the elemental contents of ethno medicinal plants was acquired by utilizing electronic databases. We reviewed only macro-elemental and trace elemental contents of 69 medicinal plant taxa, which are traditionally used in Pakistan for the treatment of sundry ailments, including anemia, jaundice, cancer, piles, diarrhea, dysentery, headache, diabetes, asthma, blood purification, sedative and ulcer. A majority of plants showed elemental contents above the permissible levels as recommended by the World health organization (WHO). As an example, the concentrations of Cadmium (Cd) and Lead (Pb) were reportedly found higher than the WHO permissible levels in 43 and 42 medicinal plants, respectively. More specifically, the concentrations of Pb (54ppm: Silybum marianum) and Cd (5.25ppm: Artemisia herba-alba) were found highest in the Asteraceae family. The reported medicinal plants contain a higher amount of trace and toxic elements. Intake of these plants as traditional medicines may trigger the accumulation of trace and toxic elements in human bodies, which can cause different types of diseases. Thus, a clear understanding about the nature of toxic substances and factors affecting their concentrations in traditional medicines are essential prerequisites for efficacious herbal therapeutics with
The modern education institutes play an important role in fostering professional talents, reproducing knowledge and studies, and forming the identities of certain academic fields and vocational communities. It is a matter of common knowledge that the absence of an official Korean medicine medical school during the Japanese colonial era was a severely disadvantageous factor in the aspects of academic progress, fostering follow-up personnel, and establishment of social capability. Therefore, the then Korean medicine circle put emphasis on inadequate official education institutes as the main factor behind oppression. Furthermore, as the measure to promote the continuance of Korean medicine, the circle regarded establishing civilian Korean medicine training schools as their long-cherished wish and strived to accomplish the mission even after liberation. This study looked into how the Korean medicine circle during the Japanese colonial era utilized civilian training schools to conduct the Korean medicine education conforming to modern medical school and examined how the operation of these training schools influenced the changes in the traditional Korean medicine. After the introduction of the Western medical science, the Korean medicine circle aimed to improve the quality of Korean medicine doctors by establishing modern Korean medicine medical schools. However, after the annexation of Korea and Japan, official Korean medicine medical schools were not established since policies were organized centered on the Western medical science. In this light, the Korean medicine circle strived to nurture the younger generation of Korean medicine by establishing and operating the civilian Korean medicine training schools after the annexation between Korea and Japan. The schools were limited in terms of scale and status but possessed the forms conforming to the modern medical schools in terms of education system. In other words, the civilian training schools not only adhered to the

The aim of this study was to analyze Internal Medicine as a subject and its requirement in each of the Universities curriculum in Mexico that offers a degree in General Medicine. By the end of the first quarter of 2014, the research was closed and 81 campuses were studied. This research was quantitative, using an analytical technique, written discourse, exploratory and purposive sampling not random and homogeneous type. The Likert questionnaire was used in this study to analyse the following variables: the record of Internal Medicine as a subject, the burden of credit, and the location of the program. The procedure consisted of three phases. First obtaining an official list of all the Universities in the Mexican Association of Colleges and Schools of Medicine. Second, obtaining an analysis of each of the Universities' curriculums, and lastly gathering each variable of the study. The results of the Universities were 63% were public and 37% private. Internal Medicine as a subject in the curriculum was 37.1%, and 20% of the universities include it for six months and 9% offer it the whole year. However, the undergraduate internship in Internal Medicine offers it 100%. In conclusion, Internal Medicine as a subject could disappear from the curriculum in General Medicine before coming to the undergraduate internship, even though the latter is declared required in hospital shifts.

Completed in 2008, Antares is now the largest water Cherenkov neutrino telescope in the Northern Hemisphere. Its main goal is to detect neutrinos from galactic and extra-galactic sources. Due to the high background rate of atmospheric muons and the high level of bioluminescence, several on-line and off-line filtering algorithms have to be applied to the raw data taken by the instrument. To be able to handle this data stream, a dedicated computing infrastructure has been set up. The paper covers the main aspects of the current official Antares computing model. This includes an overview of on-line and off-line data handling and storage. In addition, the current usage of the “IceTray” software framework for Antares data processing is highlighted. Finally, an overview of the data storage formats used for high-level analysis is given.
Hippocrates, the father of medicine, has been represented in many ways throughout the history of medicine. His influence on later medicine took different forms from one epoch to another. Hippocrates' medical doctrine was quite influential until Renaissance period, and with the arrival of modern medicine, the method or the spirit of Hippocrates had been valued more highly than his medical doctrine. Nineteenth century French medicine shows us how the influence of Hippocrates is still vivid even in the nineteenth century. Hippocrates, as the author of the Air, Water, Places, became the founder of environmental medicine with the flourishing of meteorological medicine. And in the hands of medical ideologies he also became a proclaimer of the ideology that stressed the correspondence between men, society and nature. Laennec represented Hippocrates as the true pioneer in Clinical Medicine to which he himself made a great contribution. These various images of Hippocrates show us the universal nature of his medicine.
Full Text Available The present article, signed by one prominent Romanian scholar specialized in oral and maxillo-facial surgery, evaluates the main reference points (benchmarks of the “medicine for healthy people” – as an alternative medicine set in contrast with conventional medicine. The medicine for healthy people is a more recent approach to medicine, which emphasizes health habits that prevent disease, including eating a healthier diet, getting adequate exercise, and insuring a safe environment. In this respect, there is a special connection between medicine and society as far as social life has an impact on morbidity and mortality rate, and vice versa. Medicine is indisputably an extremely complex science, but it is, also, an “art” of healing. The quality of medical performance depends upon the scientific and human quality of the practitioner. Technology is only secondary. The very large quantity of graduates of medical studies is surely at the expense of the quality of the art of healing (a clear sign that we stray from this desiderate. Sociological studies regarding the evolution of the human being prove undoubtedly that we are in obvious regression. What is the cause? Man as a self-destructing being! The solution? The return to nature and to the “medicine for healthy people”. The conditions needed to meet this goal are disclosed throughout the present paper

Nuclear medicine studies evaluate physiology on a molecular level providing earlier detection of lesions before morphologic change is evident. 99m Tc-MDP and 18 F-fluoride bone scans detect osteomyelitis earlier than radiographs and computed tomography (CT); aid in diagnosis of temporomandibular joint disorder; and evaluate activity of condylar hyperplasia, extent of Paget disease, and viability of bone grafts. 18 F-FDG PET/CT distinguish between soft tissue and bone infections and diagnose osteomyelitis complicated by fracture or surgery. FDG PET is more accurate than CT alone and has a major role in staging, restaging, and assessing response to therapy for head and neck malignancies and in detecting sequelae of therapy.

For more than two decades of activity, the European Medicines Agency has been operating as part of a network with the national medicines agencies in Europe, bringing together - in its various scienti c committees and working groups - European experts on a wide range of topics related to quality assurance, safety and ef cacy of medicines. The work carried out within the European Medicines Agency activities and the conclusions reached at European level affect millions of citizens. The European Medicines Agency considers that it is of great importance to maintain, in a sustainable and consistent manner, the active participation of general practitioners, as well as other medical specialists, in the process of medicines' evaluation and supervision. This article summarizes how the participation of doctors and health professionals in general is promoted in the European Medicines Agency activities.
Full Text Available BACKGROUND The neurosurgical patient is often a real challenge for the physicians, because of a frequent multimorbidity and a higher risk for severe complications. Cooperation between internal medicine specialist and neurosurgeon is essential to prevent the fatal effects of cranial and spinal injuries. The topic issues of medical interest in neurosurgery are the disorders of sodium balance, the glycemic control, the thromboembolic risk, the intracerebral bleeding management and the infective problems. The neurosurgeons could be worried by treating these complications that are mostly of internal medicine interest and that could unfortunately rise the risk of death or irreversible insults. AIM OF THE REVIEW This review summarizes the modality of diagnosis and therapy of the foremost concerns in neurosurgical field.
The present manuscript aims to record some general aspects of science, and in particular from the beginning of anatomic studies, during the discovery of America. We mention by Vesalio, who was the best known anatomist of his time in the Western world. In addition this establishes the legal origins of the medical profession in Spain and America, with emphasis on distinct treatments, for example, those in Peru and Chile. This manuscript contains anecdotes and accounts of the time, the use of medicines of the day, and the relationship these had with the native medicine. Finally, medical department of Chile is described, together with a mention of the first hospitals of the Republic of Chile.

A brief historical review is given of the development of the various nuclear medicine techniques which have been evolved since the discovery of X-rays and radioactivity. The role of various disciplines, such as radiobiology, radiation chemistry, radiation physics and computers in the application of radiation in medicine is discussed. (U.K.)

This book presents the fundamentals of physics as they relate to nuclear medicine in as elementary way as possible. The text concentrates solely on those facts which apply directly to the studies or to the instruments which the physician or technician will be using. After an introductory review of the necessary mathematics, the text examines the structure of matter and the nature of radioactivity. The discussion of nuclear decay processes incorporates information on negative beta decay, gamma emission, positron decay, electron capture and isomeric transitions. Alpha particles, beta particles and photons are explored in the chapter on the interaction of radiation with matter. Scintillation detectors, scanners, gamma cameras, and other imaging devices are all explored in detail. This overview of equipment is followed by a study of radionuclides in nuclear medicine and a review of statistics. The final two chapters are concerned with radiation safety and dosimetry
The ethical code by which physicians traditionally conduct themselves is based on the relationship between the physician and the patient: both work toward the goal of improving or maintaining health. Constraints on this relationship may be behaviors of patient choice (tobacco use, excessive alcohol use, sedentary behavior, and so on). The athlete-physician relationship is ethically different. Influences such as the physician's employer, the athlete's desire to play with pain and injury, and the economic consequences of playing or not complicate medical decisions. This perspective suggests something different and even unique about the ethics of the sports medicine practitioner. This article explores the differences fostering the ethical tight ropes that sports physicians walk in their sports medicine practices.

The nature of mankind is a concern for those in need. Disasters, both natural and manmade, have been with us since the beginning of recorded history but media coverage of them is a relatively new phenomenon. When these factors come together, there is great potential to both identify and serve the sick and injured. However, the mass media by its nature tends to enhance the humanistic aspect of rescue while minimizing the practical problems involved. We describe a recent scenario in Haiti that puts some of these complications into a practical perspective.

A focus often exists in dental practice on the maintenance and management of the dentition and the periodontium, however, conditions of the oral mucosa and orofacial pain can cause significant problems for older patients. Oral mucosal conditions are more prevalent in older patients and many orofacial pain disorders, such as burning mouth syndrome and trigeminal neuralgia, are more common in patients over the age of 50 years. Although these conditions may not be routinely managed in general practice, identification of these patients in primary care and appropriate referral will lead to more prompt and effective treatment. CLINICAL RELEVANCE: Dental practitioners need to be able to identify what is considered to be within the normal physiological limits of the ageing oral tissue and hence what is abnormal and requires further investigation to facilitate appropriate referral.

We begin by distinguishing computationalism from a number of other theses that are sometimes conflated with it. We also distinguish between several important kinds of computation: computation in a generic sense, digital computation, and analog computation. Then, we defend a weak version of computationalism-neural processes are computations in the generic sense. After that, we reject on empirical grounds the common assimilation of neural computation to either analog or digital computation, concluding that neural computation is sui generis. Analog computation requires continuous signals; digital computation requires strings of digits. But current neuroscientific evidence indicates that typical neural signals, such as spike trains, are graded like continuous signals but are constituted by discrete functional elements (spikes); thus, typical neural signals are neither continuous signals nor strings of digits. It follows that neural computation is sui generis. Finally, we highlight three important consequences of a proper understanding of neural computation for the theory of cognition. First, understanding neural computation requires a specially designed mathematical theory (or theories) rather than the mathematical theories of analog or digital computation. Second, several popular views about neural computation turn out to be incorrect. Third, computational theories of cognition that rely on non-neural notions of computation ought to be replaced or reinterpreted in terms of neural computation.

Full Text Available The purpose of this paper is to present a review of highly developed medicinal usages of plants in the treatment of cancer. In the last decades, the cancer treatment has been included in this range of plant use, due to plant active substances. Active substances or secondary metabolites are generally known for their widespread application. When it comes to the cancer treatment, these substances affect the uncontrolled cell division. Therefore, the plants which are the source of these substances are proved to be irreplaceable in this field of medicine. This paper deals with some of the most significant plants well known for their multiple aspects of beneficial medicinal influence. The group of the plants described is comprised of the following species: Taxus brevifolia (Taxaceae, Catharanthus roseus (Apocynaceae, Podophyllum peltatum (Berberidaceae, Camptotheca accuminata (Cornaceae, and Cephalotaxus harringtonia (Cephalotaxaceae. The comprehensive description of the plants in this paper includes the morphological characteristics, the features and the representation of the molecular structures of active substances, the particular influence that these active substances have and the general importance of the substances as seen from the aspect of cancer treatment mostly with reference to the impacts on cell cycle.

This discussion of the relations between folklore and popular medicine in the Amazon takes Canuto Azevedo's story "Filhos do boto" (Children of the porpoise) as an analytical reference point. Replete with elements of cultural reality, folk tales can serve as historical testimonies expressing clashes between different traditions. Folk records are fruit of what is often a quarrelsome dialogue between folklorists, social scientists, physicians, and pajés and their followers, and their analysis should take into account the conditions under which they were produced. Based on the imaginary attached to the figure of the porpoise--a seductive creature with healing powers--the article explores how we might expand knowledge of popular medicine as practiced in the Amazon, where the shamanistic rite known as pajelança cabocla has a strong presence.
Since its official opening on 26 January 1960, the HIFAR research reactor operated by the Australian Nuclear Science and Technology Organisation (ANSTO) at Lucas Heights near Sydney has been used to support an expanding nuclear medicine market. HIFAR has characteristics which make it very suitable for this role and the effect has been to make ANSTO the dominant supplier of reactor-based radiopharmaceuticals in Australia and a significant exporter. While HIFAR has capacity to support limited increased production, its future requires government decisions. The author concluded that the absence of an operational research reactor in Australia and the lack of another local source of neutrons could directly affect the practice of nuclear medicine in the country and the level of presently increasing exports

Medicine has historically been a field where the provider of the service (physician, nurse) has a significant amount of power as compared with the recipient of the service (the patient). For the most part, this power is relatively consistent, and the power dynamic is rarely disrupted. In this essay, I share a personal experience in which a racist rant by a patient seemingly reverses the power dynamic. As the physician, I faced the realization that I may not have as much power as I believed, but fortunately I had some tools that allowed for my resilience. It is my hope that this paper will strengthen other family physicians and professional minorities that are victims of racism, discrimination, and prejudice for their race, sex, ability, sexual orientation, religion, and other axes of discrimination. © 2016 Annals of Family Medicine, Inc.

The profession of laboratory medicine differs between countries within the European Union (EU) in many respects. The objective of professional organizations of the promotion of mutual recognition of specialists within the EU is closely related to the free movement of people. This policy translates to equivalence of standards and harmonization of the training curriculum. The aim of the present study is the description of the organization and practice of laboratory medicine within the countries that constitute the EU. A questionnaire covering many aspects of the profession was sent to delegates of the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) and Union Européenne de Médecins Spécialistes (UEMS) of the 28 EU countries. Results were sent to the delegates for confirmation. Many differences between countries were identified: predominantly medical or scientific professionals; a broad or limited professional field of interest; inclusion of patient treatment; formal or absent recognition; a regulated or absent formal training program; general or minor application of a quality system based on ISO Norms. The harmonization of the postgraduate training of both clinical chemists and of laboratory physicians has been a goal for many years. Differences in the organization of the laboratory professions still exist in the respective countries which all have a long historical development with their own rationality. It is an important challenge to harmonize our profession, and difficult choices will need to be made. Recent developments with respect to the directive on Recognition of Professional Qualifications call for new initiatives to harmonize laboratory medicine both across national borders, and across the borders of scientific and medical professions.

The authors of this article describe the history of nuclear medicine from its beginning at the end of the 19th century when radioactivity was discovered, basic considerations which describe briefly the properties of radionuclides with special reference to the ones which are suited to medical applications and in general terms the diagnostic techniques that are current. The article also includes a segment on the radionuclide technetium 99m, explaining why it is ideal for organ imaging and how it is utilised in a range of radiopharmaceuticals for investigations into many areas of the human body. The radiation risk to the patient, including tabulated radiation exposures for a few of the more common nuclear medicine studies, is dealt with. The article explains that a greater risk to life from not having the test performed is used as the criterion for justifying whether a nuclear medicine procedure is performed or not. The article finally describes the scope of the techniques and the areas of the body which are routinely examined and are exemplified with numerous illustrations. (J.R.)

Is there a rational and ethical basis for efforts to rescue individuals in dire straits? When does rescue have ethical support, and when does it reflect an irrational impulse? This paper defines a Rule of Rescue and shows its intuitive appeal. It then proceeds to argue that this rule lacks support from standard principles of justice and from ethical principles more broadly, and should be rejected in many situations. I distinguish between agent-relative and agent-neutral reasons, and argue that the Rule of Rescue qualifies only in a narrow range of cases where agent-relative considerations apply. I conclude that it would be wise to set aside the Rule of Rescue in many cases, especially those involving public policies, where it has only weak normative justification. The broader implications of this analysis are noted.

Controversies and debates surrounding race have long been a fixture in American medicine. In the past, the biological concept of race-the idea that race is biologically determined and meaningful-has served to justify the institution of slavery and the conduct of unethical research trials. Although these days may seem far behind, contemporary debates over the race-specific approval of drugs and the significance of genetic differences are evidence that race still yields tremendous influence on medical research and clinical practice. In many ways, the use of race in medicine today reflects the internalisation of racial hierarchies borne out of the history of slavery and state-mandated segregation, and there is still much uncertainty over its benefits and harms. Although using race in research can help elucidate disparities, the reflexive use of race as a variable runs the risk of reifying the biological concept of race and blinding researchers to important underlying factors such as socioeconomic status. Similarly, in clinical practice, the use of race in assessing a patient's risk of certain conditions (eg, sickle cell) turns harmful when the heuristic becomes a rule. Through selected historical and contemporary examples, I aim to show how the biological concept of race that gave rise to past abuses remains alive and harmful, and propose changes in medical education as a potential solution. By learning from the past, today's physicians will be better armed to discern-and correct-the ways in which contemporary medicine perpetuates historical injustices.

Full Text Available Clinical practice guidelines have been developed for many common conditions based on data from randomized controlled trials. When medicine is informed solely by clinical practice guidelines, however, the patient is not treated as an individual, but rather a member of a group. Precision medicine, as defined herein, characterizes unique biological characteristics of the individual or of specimens obtained from an individual to tailor diagnostics and therapeutics to a specific patient. These unique biological characteristics are defined by the tools of precision medicine: genomics, proteomics, metabolomics, epigenomics, pharmacogenomics, and other “-omics.” Personalized medicine, as defined herein, uses additional information about the individual derived from knowing the patient as a person. These unique personal characteristics are defined by tools known as personomics which takes into account an individual’s personality, preferences, values, goals, health beliefs, social support network, financial resources, and unique life circumstances that affect how and when a given health condition will manifest in that person and how that condition will respond to treatment. In this paradigm, precision medicine may be considered a necessary step in the evolution of medical care to personalized medicine, with personomics as the missing link.

Full Text Available Complementary and alternative medicine has been increasingly utilized by cancer patients in developed countries. Among the various forms of complementary and alternative medicine, Traditional Chinese Medicine is one of the few that has a well constructed theoretical framework and established treatment approaches for diseases including cancer. Recent research has revealed growing evidence suggesting that Traditional Chinese Medicine is effective in the supportive care of cancer patients during and after major conventional cancer treatments. This paper succinctly summarizes some published clinical evidence and meta-analyses which support the usage of various Traditional Chinese Medicine treatment strategies including Chinese herbal medicine, acupuncture and Qigong in supportive cancer care.
I'll discuss how computational complexity---the study of what can and can't be feasibly computed---has been interacting with physics in interesting and unexpected ways. I'll first give a crash course about computer science's P vs. NP problem, as well as about the capabilities and limits of quantum computers. I'll then touch on speculative models of computation that would go even beyond quantum computers, using (for example) hypothetical nonlinearities in the Schrodinger equation. Finally, I'll discuss BosonSampling ---a proposal for a simple form of quantum computing, which nevertheless seems intractable to simulate using a classical computer---as well as the role of computational complexity in the black hole information puzzle.

Liver injury caused by traditional Chinese medicines (TCMs) is reported from many countries around the world. TCM hepatotoxicity has attracted worldwide concerns. This study aims to develop a more applicable and optimal tool to evaluate TCM hepatotoxicity. A quantitative structure-activity relationship (QSAR) analysis was performed based on published data and U.S. Food and Drug Administration's Liver Toxicity Knowledge Base (LTKB). Eleven herbal ingredients with proven liver toxicity in the literature were added into the dataset besides chemicals from LTKB. The finally generated QSAR model yielded a sensitivity of 83.8%, a specificity of 70.1%, and an accuracy of 80.2%. Among the externally tested 20 ingredients from TCMs, 14 hepatotoxic ingredients were all accurately identified by the QSAR model derived from the dataset containing natural hepatotoxins. Adding natural hepatotoxins into the dataset makes the QSAR model more applicable for TCM hepatotoxicity assessment, which provides a right direction in the methodology study for TCM safety evaluation. The generated QSAR model has the practical value to prioritize the hepatotoxicity risk of TCM compounds. Furthermore, an open-access international specialized database on TCM hepatotoxicity should be quickly established.

Curcumin is a constituent (up to ∼5%) of the traditional medicine known as turmeric. Interest in the therapeutic use of turmeric and the relative ease of isolation of curcuminoids has led to their extensive investigation. Curcumin has recently been classified as both a PAINS (pan-assay interference compounds) and an IMPS (invalid metabolic panaceas) candidate. The likely false activity of curcumin in vitro and in vivo has resulted in >120 clinical trials of curcuminoids against several diseases. No double-blinded, placebo controlled clinical trial of curcumin has been successful. This manuscript reviews the essential medicinal chemistry of curcumin and provides evidence that curcumin is an unstable, reactive, nonbioavailable compound and, therefore, a highly improbable lead. On the basis of this in-depth evaluation, potential new directions for research on curcuminoids are discussed.
Full Text Available Medications and their prices are key issues for healthcare. Although access to medicines at affordable prices had been specified as a key objective of the European Health Policy, it seems that these goals have not been achieved. Therefore, we attempted an evaluation of affordability of selected medicines at full prices.The analysis concerned 2012 and was conducted between 2013 and 2015 in all the European Union (EU countries divided into 3 groups depending on the date of their accession to the EU. Finally, we considered 9 originators used in the treatment of schizophrenia and multiple sclerosis. Information on drug prices were collected from pharmacies. Participation in the study was voluntary and anonymous in order to avoid accusations of advertising. To evaluate affordability, several factors were used (e.g. minimum earnings and Gini coefficient. Due to unavailability in some countries, the exact number of analyzed medicines varies.Drug prices vary significantly between EU Member States. Almost eleven fold difference was observed between Germany (EUR 1451.17 and Croatia (EUR 132.77 in relation to Interferone beta-1a 22 μg. Generally, prices were the highest in Germany. The cheapest drugs were found in various countries but never in the poorest ones like Bulgaria or Romania. Discrepancies in wages were observed too (the smallest minimum wage was EUR 138.00 in Bulgaria and the highest EUR 1801.00 in Luxembourg. Full price of olanzapine 5mg, however, was higher in Bulgaria (EUR 64.53 than, for instance, in Belgium (EUR 37.26.Analyzed medications are still unaffordable for many citizens of the EU. Besides, access to medicines is also impaired e.g. due to parallel trade. Unaffordability of medications may lead to the patients' non-compliance and therefore to increased direct and indirect costs of treatment. Common European solutions are needed to achieve a real affordability and accessibility of medications.

This guidebook for clinical nuclear medicine is written as a description of how nuclear medicine procedures should be used by clinicians in evaluating their patients. It is designed to assist medical students and physicians in becoming acquainted with nuclear medicine techniques for detecting and evaluating most common disorders. The material provides an introduction to, not a textbook of, nuclear medicine. Each chapter is devoted to a particular organ system or topic relevant to the risks and benefits involved in nuclear medicine studies. The emphasis is on presenting the rationales for ordering the various clinical imaging procedures performed in most nuclear medicine departments. Where appropriate, alternative imaging modalities including ultrasound, computed tomography imaging, and radiographic special procedures are discussed. Comparative data between nuclear medicine imaging and other modalities are presented to help guide the practicing clinician in the selection of the most appropriate procedure for a given problem.
The practice of medicine is often represented as a dualism: is medicine a 'science' or an 'art'? This dualism has been long-lasting, with evident appeal for the medical profession. It also appears to have been rhetorically powerful, for example in enabling clinicians to resist the encroachment of 'scientific' evidence-based medicine into core areas of medical work such as individual clinical judgement. In this article I want to make the case for a more valid conceptualisation of medical practice: that it is a 'craft' activity. The case I make is founded on a theoretical synthesis of the concept of craft, combined with an analysis of ethnographic observations of routine medical practice in intensive care. For this context the craft aspects of medical work can be seen in how biomedical and other types of knowledge are used in practice, the embodied skills and practical judgement of practitioners and the technological and material environment. These aspects are brought together in two conceptual dimensions for 'craft': first, the application of knowledge; second, interaction with the material world. Some practical and political implications of a 'craft' metaphor for medical practice are noted. © 2013 The Author.

Over the past decade, the number of countries reporting falsified (fake, spurious/falsely labeled/counterfeit) medicines and the types and quantities of fraudulent drugs being distributed have increased greatly. The obstacles in combating falsified pharmaceuticals include 1) lack of consensus on definitions, 2) paucity of reliable and scalable technology to detect fakes before they reach patients, 3) poor global and national leadership and accountability systems for combating this scourge, and 4) deficient manufacturing and regulatory challenges, especially in China and India where fake products often originate. The major needs to improve the quality of the world's medicines fall into three main areas: 1) research to develop and compare accurate and affordable tools to identify high-quality drugs at all levels of distribution; 2) an international convention and national legislation to facilitate production and utilization of high-quality drugs and protect all countries from the criminal and the negligent who make, distribute, and sell life-threatening products; and 3) a highly qualified, well-supported international science and public health organization that will establish standards, drug-quality surveillance, and training programs like the U.S. Food and Drug Administration. Such leadership would give authoritative guidance for countries in cooperation with national medical regulatory agencies, pharmaceutical companies, and international agencies, all of which have an urgent interest and investment in ensuring that patients throughout the world have access to good quality medicines. The organization would also advocate strongly for including targets for achieving good quality medicines in the United Nations Millennium Development Goals and Sustainable Development Goals.

A variety of methods have been developed to assess tumor response to therapy. Standardized qualitative criteria based on 18F-fluoro-deoxyglucose PET/computed tomography have been proposed to evaluate the treatment effectiveness in specific cancers and these allow more accurate therapy response assessment and survival prognostication. Multiple studies have addressed the utility of the volumetric PET biomarkers as prognostic indicators but there is no consensus about the preferred segmentation methodology for these metrics. Heterogeneous intratumoral uptake was proposed as a novel PET metric for therapy response assessment. PET imaging techniques will be used to study the biological behavior of cancers during therapy.

The activities of the occupation health physicians also at the Karlsruhe Nuclear Research Center have experienced a change in focus over the past few decades, the causes of which are in the working environment and in work processes. The causes and conditions of diseases at work must be recognized and preventive measures instituted, but there is also need to design the working environment in terms of occupational physiology and industrial hygiene so as to meet human requirements. This includes the use of sociological and psychological concepts and methods in modern occupational medicine. This recognition necessitates the appropriate efforts to be made both in scientific research and in daily medical practive. Modern working life is determined by the joint action of physical and psychological impacts, with more and more importance attaching to psychosensoric impacts. As a result of this development, occupational health physicians spend increasingly more time and effort in medical consulting and on problems in occupational medicine, social medicine, and ergonomics.

Recent societal events highlight inequities experienced by underrepresented and marginalized communities. These inequities are the impetus for ongoing efforts in academic medicine to create inclusive educational and patient care environments for diverse stakeholders. Frequently, approaches focus on singular populations or broad macroscopic concepts and do not always elucidate the complexities that arise at the intersection between multiple identities and life experiences. Intersectionality acknowledges multidimensional aspects of identity inclusive of historical, structural, and cultural factors. Understanding how multiple identity experiences impact different individuals, from patients to trainees to providers, is critical for improving health care education and delivery. Building on existing work within academic medicine, this Commentary outlines six key recommendations to advance intersectionality in academic medicine: embrace personal and collective loci of responsibility; examine and rectify unbalanced power dynamics; celebrate visibility and intersectional innovation; engage all stakeholders in the process of change; select and analyze meaningful metrics; and sustain the commitment to achieving health equity over time. Members of the academic medical community committed to advancing health equity can use these recommendations to promote and maintain meaningful changes that recognize and respond to the multidimensional voices and expressed needs of all individuals engaged in providing and receiving health care.

Full Text Available A great wealth of information is hidden amid medical research data that in some cases cannot be easily analyzed, if at all, using classical statistical methods. Inspired by nature, metaheuristic algorithms have been developed to offer optimal or near-optimal solutions to complex data analysis and decision-making tasks in a reasonable time. Due to their powerful features, metaheuristic algorithms have frequently been used in other fields of sciences. In medicine, however, the use of these algorithms are not known by physicians who may well benefit by applying them to solve complex medical problems. Therefore, in this paper, we introduce the genetic algorithm and its applications in medicine. The use of the genetic algorithm has promising implications in various medical specialties including radiology, radiotherapy, oncology, pediatrics, cardiology, endocrinology, surgery, obstetrics and gynecology, pulmonology, infectious diseases, orthopedics, rehabilitation medicine, neurology, pharmacotherapy, and health care management. This review introduces the applications of the genetic algorithm in disease screening, diagnosis, treatment planning, pharmacovigilance, prognosis, and health care management, and enables physicians to envision possible applications of this metaheuristic method in their medical career.

Over the past decade, addiction medicine training curricula have been developed to prepare physicians to work with substance use disorder patients. This review paper aimed at (1) summarizing scientific publications that outline the content of addiction medicine curricula and (2) evaluating the evidence for efficacy for training in addiction medicine. We carried out a literature search on articles about addiction medicine training initiatives across the world, using PubMed, PsychINFO and EMBASE with the following search terms 'substance abuse, addiction medicine, education and training.' We found 29 articles on addiction medicine curricula at various academic levels. Nine studies reported on the need for addiction medicine training, 9 described addiction medicine curricula at various academic levels, and 11 described efficacy on addiction medicine curricula. Several key competences in addiction medicine were identified. Efficacy studies show that even short addiction medicine training programs can be effective in improving knowledge, skills and attitudes related to addiction medicine. A more uniform approach to addiction medicine training in terms of content and accreditation is discussed. © 2015 S. Karger AG, Basel.

Placenta has a long history of use for treating burns and wounds. It is a rich source of collagen and other extracellular matrix proteins, tissue reparative growth factors, and stem cells, including mesenchymal stem cells (MSCs). Recent data show its therapeutic potential for orthopaedic sports medicine indications. To provide orthopaedic surgeons with an anatomic description of the placenta, to characterize its cellular composition, and to review the literature reporting the use of placenta-derived cells and placental tissue allografts for orthopaedic sports medicine indications in animal models and in humans. Systematic review. Using a total of 63 keyword combinations, the PubMed and MEDLINE databases were searched for published articles describing the use of placental cells and/or tissue for orthopaedic sports medicine indications. Information was collected on placental tissue type, indications, animal model, study design, treatment regimen, safety, and efficacy outcomes. Results were categorized by indication and subcategorized by animal model. Outcomes for 29 animal studies and 6 human studies reporting the use of placenta-derived therapeutics were generally positive; however, the placental tissue source, clinical indication, and administration route were highly variable across these studies. Fourteen animal studies described the use of placental tissue for tendon injuries, 13 studies for osteoarthritis or articular cartilage injuries, 3 for ligament injuries, and 1 for synovitis. Both placenta-derived culture-expanded cells (epithelial cells or MSCs) and placental tissue allografts were used in animal studies. In all human studies, commercial placental allografts were used. Five of 6 human studies examined the treatment of foot and ankle pathological conditions, and 1 studied the treatment of knee osteoarthritis. A review of the small number of reported studies revealed a high degree of variability in placental cell types, placental tissue preparation, routes

The promise of precision medicine for cancer is already being realized with the recent introduction of many targeted therapies, some with companion diagnostic tests that identify patients most likely to benefit from treatment. The utility of molecular profiling of cancer to identify actionable aberrations has been suggested by several small clinical trials conducted in patients with advanced cancer and by many anecdotes but is yet to be proven in well-designed, prospective, randomized trials. Several trials that will definitively test this strategy are now underway or soon to be launched. Melanoma, a disease once largely untreatable when metastatic, may be a paradigm for understanding how the molecular drivers of a disease can lead to highly effective targeted therapies, as well as for realizing the enormous therapeutic potential of unleashing the immune system against cancer to produce long-term disease control. Looking to the future, advanced omics technologies and computational techniques will enable assessment of not only genomic variants, as performed today, but also of pathway and network aberrations that will greatly facilitate selection of drug combinations likely to benefit specific patients. As our deepening understanding of tumor biology converges with rapid advances in measurement science and technology and computational analysis, we have an enormous opportunity to create a future for precision medicine in oncology that provides for highly specific, minimally toxic, and dramatically effective treatment for each patient.

Allergic rhinitis has long been a worldwide health problem with a global growth trend. The use of traditional Chinese medicines alone or integrated Chinese-Western medicines for its treatment is quite common in Taiwan. Respiratory diseases account for the majority of outpatient traditional Chinese medicine treatment, while allergic rhinitis accounts for the majority of respiratory diseases. We hereby conduct a comparative analysis between traditional Chinese medicine treatments and western medicine treatments for allergic rhinitis in Taiwan. The results of the analysis on the prescription difference of traditional Chinese medicine and western medicine treatments would be helpful to clinical guide and health policy decision making of ethnopharmacological therapy. Patients diagnosed as allergic rhinitis with diagnostic code 470-478 (ICD-9-CM) were selected as subjects from 2009-2010 National Health Insurance Research Database based on the claim data from the nationwide National Health Insurance in Taiwan. This retrospective study used Chi-Square test to test the effects of gender and age on visit of traditional Chinese medicine, western medicine, and integrated Chinese-Western medicine treatments. A total of 45,804 patients diagnosed as allergic rhinitis with ICD-9-CM 470-478 were identified from 2009-2010 NHIRD. There were 36,874 subjects for western medicine treatment alone, 5829 subjects for traditional Chinese medicine treatment alone, and 3101 subjects for integrated Chinese-Western medicine treatment. Female patients were more than male in three treatments. 0-9 years children had the highest visit frequency in western medicine and integrated Chinese-Western medicine groups, while 10-19 years young-age rank the highest in traditional Chinese medicine group. The Chi-square test of independence showed that the effects of gender and age on visit of three treatments were significant. The prescription drugs of western medicine treatment alone were almost for

With the amendment of the German Medicinal Products Act in 1976 and the inclusion of naturopathy and homeopathy into the German Medical Licensure Act from 1988, the German government set up a comparatively favorable framework for Complementary and Alternative Medicine (CAM). But no comprehensive integration into the academic operating systems followed, because the universities as well as the legislative body seemed to have no further interest in CAM. Therefore, research projects in the field and suitable professorships had and still have to be financed by third-party funds. Notwithstanding the success of several CAM-projects, no sustainable development could be established: When the third-party funding runs off and the protagonists retire the institutional structures are supposed to vanish as well. Although the public demand for CAM is high in Germany, the administration detached homeopathy as a compulsory subject from the German Medical Licensure Act in 2002 and restricted severely the refunding of naturopathic medicines by the statutory health insurance in 2004. Moreover, the trend for CAM bashing takes root in the media. Unfortunately the CAM scene does not close ranks and is incapable to implement fundamental data collection processes into daily clinical routine: A wide range of data could justify further efforts to the government as well as to the scientific community. To say something positive, it must be mentioned that the scientific standard of CAM research is high for the most part and that third-party funded projects deliver remarkable results ever and on.

In human medicine, the information infrastructure that supports the knowledge translation processes of exchange, synthesis, dissemination, and application of the best clinical intervention research has developed significantly in the past 15 years, facilitating the uptake of research evidence by clinicians as well as the practice of evidence-based medicine. Seven of the key elements of this improved information infrastructure are clinical trial registries, research reporting standards, systematic reviews, organizations that support the production of systematic reviews, the indexing of clinical intervention research in MEDLINE, clinical search filters for MEDLINE, and point-of-care decision support information resources. The objective of this paper is to describe why these elements are important for evidence-based medicine, the key developments and issues related to these seven information infrastructure elements in human medicine, how these 7 elements compare with the corresponding infrastructure elements in veterinary medicine, and how all of these factors affect the translation of clinical intervention research into clinical practice. A focused search of the Ovid MEDLINE database was conducted for English language journal literature published between 2000 and 2010. Two bibliographies were consulted and selected national and international Web sites were searched using Google. The literature reviewed indicates that the information infrastructure supporting evidence-based veterinary medicine practice in all of the 7 elements reviewed is significantly underdeveloped in relation to the corresponding information infrastructure in human medicine. This lack of development creates barriers to the timely translation of veterinary medicine research into clinical practice and also to the conduct of both primary clinical intervention research and synthesis research.
Full Text Available Several species of the family Caryophyllaceae are widely used by many ethnic communities as traditional medicine throughout the world. The highest number of plants of the family are used in Chinese traditional medicine. The ethnopharmacologial studies of this family indicate that plants of the family possess anticancer, antibacterial, antifungal, antiviral, antioxidant, and anti-inflammatory properties. Other miscellaneous properties reported are ribosome inactivation properties, inhibition of prostatic enlargement in rats, and inhibition of intestinal enzyme carboxyelasterase in rats, cerebro-protective activity, and antiobesity in rats. Few reviews have been published yet, providing information regarding medicinal plants of the family and their biomedical properties. All published reviews have focused either on a particular taxa or a few species. The present review is focused on the traditional medicinal uses of the plants of the family Caryophyllaceae along with phytochemical and pharmacological studies of the family. A study of the literature revealed significant traditional medicinal importance of the family. Major chemical constituents of Caryophyllceae are saponins, Phytoecdysteroids, benzenoids, phenyl propanoids, and nitrogen containing compounds. The most important property of plants of the family is anticancer activity and is shown by the large number of plant species studied. This review of traditional medicinal and pharmacological uses of plants of the family, provide a ground for future research in the family.

Controversies and debates surrounding race have long been a fixture in American medicine. In the past, the biological concept of race—the idea that race is biologically determined and meaningful—has served to justify the institution of slavery and the conduct of unethical research trials. Although these days may seem far behind, contemporary debates over the race-specific approval of drugs and the significance of genetic differences are evidence that race still yields tremendous influence on medical research and clinical practice. In many ways, the use of race in medicine today reflects the internalization of racial hierarchies borne out of the history of slavery and state-mandated segregation, and there is still much uncertainty over its benefits and harms. Although using race in research can help elucidate disparities, the reflexive use of race as a variable runs the risk of reifying the biological concept of race and blinding researchers to important underlying factors such as socioeconomic status. Similarly, in clinical practice, the use of race in assessing a patient’s risk of certain conditions (e.g., sickle cell) turns harmful when the heuristic becomes a rule. Through selected historical and contemporary examples, I aim to show how the biological concept of race that gave rise to past abuses remains alive and harmful and propose changes in medical education as a potential solution. By learning from the past, today’s physicians will be better armed to discern—and correct—the ways in which contemporary medicine perpetuates historical injustices. PMID:23988563
One of the fundamental advances of the transition of the Middle Ages to the Renaissance was the rediscovery of the Greek philosophers. Among the greatest representatives of this epoch we find the Cordovan doctor and philosopher Averroes (Ibn Rushd) who, with his commentaries on the works of Aristotle, brought a new philosophical vision to Western Europe. His contribution to medicine has been overshadowed to some extent by this great work of philosophy. Our intention is to evaluate, in the context of the neurosciences, the vision of health and sickness that he left us in his book "The Book of the Principles of Medicine. The organisation of the Kulliyat is based on Aristotelian concepts. Averroes regarded the nervous system not as single entity but rather as a complex of various elements. The anatomy of the nervous system is studied in two parts: the encephalus and the periphery. Both the encephalic nervous system and the sensory organs are regarded as heterogeneous organs. Averroes structures the anatomical order without taking into account the local movements of the living body. The mission of the senses is to maintain contact between external reality and the structure of the organism. This requires an external process, a point of union and an internal process. The ultimate goal is the preservation of health in a balanced disposition and the cure of disease in the organism in disequilibrium.

Before the new round of healthcare reform in China, primary healthcare providers could obtain a fixed 15 % or greater mark-up of profits by prescribing and selling medicines. There were concerns that this perverse incentive was a key cause of irrational medicine use. China's new Essential Medicines Program (EMP) was launched in 2009 as part of the national health sector reform initiatives. One of its core policies was to eliminate primary care providers' economic incentives to overprescribe or prescribe unnecessarily expensive drugs, which were regarded as consequences of China's traditional financing system for health institutions. The objective of the study was to measure changes in prescribing patterns in primary healthcare facilities after the removal of the economic incentives for physicians to overprescribe as a result of the implementation of the EMP. A comparison design was applied to 8,258 prescriptions in 2007 and 8,278 prescriptions in 2010, from 83 primary healthcare facilities nationwide. Indicators were adopted to evaluate medicine utilization, which included overall number of medicines, average number of Western and traditional Chinese medicines, pharmaceutical expenditure per outpatient prescription, and proportion of prescriptions that contained two or more antibiotics. We further assessed the use of medicines (antibiotics, infusion, hormones, and intravenous injection) per disease-specific prescription for hypertension, diabetes, coronary artery heart disease, bronchitis, upper respiratory tract infection, and gastritis. A difference-in-difference analysis was employed to evaluate the net policy effect. Overall changes in indicators were not found to be statistically significant between the 2 years. The results varied for different diseases. The number of Western drugs per outpatient prescription decreased while that of traditional Chinese medicines increased. Overuse of antibiotics remained an extensive problem in the treatment of many diseases

Full text: The nuclear medicine has rather strongly determined the place in clinical and diagnostic practice. Statistical researches show, that, even despite of the certain successes in treatment of many diseases, rather high death rate at cardiovascular, oncological and many other diseases. The urgency of clinical tasks connected with a state of health of the population puts before nuclear medicine a (task) on development and introduction of new methods of diagnostics and therapy. The nuclear medicine is characterized by some number of diagnostic and therapeutic methods which application frequently does not have other alternative. The methods of visualization used in nuclear medicine, are full informative, exact and have ability to reveal structurally functional changes of bodies and fabrics practically at a cellular level. To present time diagnostic radiopharmacy (Ph) wed practically in all clinical areas of medicine. In world practice steady growth of increase of manufacture as diagnostic and radiotherapeutic RP was planned. The even greater (reduction) of potential risk one and of conditions by which development of nuclear medicine in the near future is defined is at realization of the procedures connected to application of radioactive preparations and reduction of beam loadings on the patient. An important point in the clinic-diagnostic field is replacement the RP on short-lived and ultra short-lived. Among examples of such transition it is necessary to name replacement 131 I in diagnostic application on 123 I, and also active introduction PET. It is possible to call essentially new direction of development of technologies of the directed transport the open radioactive isotopes and RP to pathology changed bodies or organisms demanding realization of diagnostic procedures or selective beam therapy. However, despite of huge potential opportunities of the domestic nuclear industry, even such old method as the radiotherapy I-131 - is used by iodine in our country

It had attracted considerable attentions in South and North America (notably in USA, Brazil, and Argentina, India and Pakistan. Although it is not dominantly popular in North America, constant growth has been nevertheless noted. Over the last thirty years, homeopathy has also developed or appeared in South Africa, Tunisia, Morocco, Venezuela, Israel, and Australia, etc. Result & suggestion : As over 300 million patients have put their trust in homeopathy, the study of the integration of homeopathy to oriental medicine, its development and feasibility in Korea are urgently needed. The products, substances, compositions of Homeopathic drugs are very similar to those of oriental medicine theory. Therefore their preparations and applications should prescribed and practised exclusively by oriental doctors. Applying the homeopathic theory and its preparation techniques to oriental medicine, the herbal acupuncture preparation should be modernized and various oriental products are to be developed. To this end, government and herbal acupuncture society need to interact each other for the development of oriental medicine.

There has been increased interest in cannabis as a medicine both nationally and internationally. Internationally, cannabis is accepted as a medication for a variety of purposes in a variety of legal guises and this, associated with anecdotes of the utility of cannabis as medication has led for calls for it to be 'medicalised' in New Zealand. This viewpoint discusses the issues associated with this approach to accessing cannabis and some of the difficulties that may be associated with it. It is important doctors are at the forefront of the debate surrounding medicalised cannabis. Recommendations as to the ongoing debate are offered.

Arthropod-borne viruses (arboviruses) are an important threat to human and animal health globally. Among these, zoonotic diseases account for billions of cases of human illness and millions of deaths every year, representing an increasing public health problem. Chikungunya virus belongs to the genus Alphavirus of the family Togariridae, and is transmitted mainly by the bite of female mosquitoes of the Aedes aegypti and/or A. albopictus species. The focus of this review will be on the medicinal chemistry of Chikungunya virus, including synthetic and natural products, as well as rationally designed compounds. Copyright © 2017 Elsevier Ltd.

Technological advances enabling us to personalise medical interventions at the biological level must be matched by parallel advances in how we support the informed choices essential to patient and public participation. We cannot take participation for granted. To be truly personalised, medicine must take account of the perceptions and capabilities that shape participation. To do this, we need a better understanding of how people perceive personalised medicine and how they judge its value and risks. To realise the promise of 4P medicine we need to personalise at the psychosocial as well as biological dimension, putting the person into personalised medicine.

Phthalates are excipients in drug formulations. However, concerns have been raised about the effects of particular phthalates on reproduction and development. As a result the EMA has introduced guidelines for permitted daily exposure (PDE) limits for certain phthalates. Therefore, the objective of this study was to identify UK licensed medicines that contain the relevant phthalates and determine if they fall within the recommended PDE. The eMC was used to identify which UK licensed medicines contain the phthalates in question. Companies were then contacted for information on the phthalate levels in their products, which was compared with the PDE recommended by the EMA. The eMC search revealed that 54 medicines contained at least one of the phthalates in question. However, only six medicines, namely Asacol 800 mg MR (Warner Chilcott UK), Epilim 200 Gastro-resistant tablets (Sanofi), Prednisolone 2.5 mg and 5 mg Gastro-resistant tablets (Actavis UK), Vivotif (Crucell Italy S.r.l), and Zentiva 200 mg Gastro-resistant tablets (Winthrop Pharmaceuticals UK), were identified as containing levels that exceeded the recommended PDE. These findings indicate that very few UK licensed medicines will be affected by the proposed EMA guidelines. For those medicines identified as exceeding recommendations, these findings highlight the need to instigate a risk-benefit review.

Abstract Basing ourselves on the writings of Hans Jonas, we offer to psychosomatic medicine a philosophy of life that surmounts the mind-body dualism which has plagued Western thought since the origins of modern science in seventeenth century Europe. Any present-day account of reality must draw upon everything we know about the living and the non-living. Since we are living beings ourselves, we know what it means to be alive from our own first-hand experience. Therefore, our philosophy of lif...

This article analyses the different connotations of "normality" and "being natural," bringing together the theoretical discussion from both human medicine and veterinary medicine. We show how the interpretations of the concepts in the different areas could be mutually fruitful. It appears that the conceptions of "natural" are more elaborate in veterinary medicine, and can be of value to human medicine. In particular they can nuance and correct conceptions of nature in human medicine that may be too idealistic. Correspondingly, the wide ranging conceptions of "normal" in human medicine may enrich conceptions in veterinary medicine, where the discussions seem to be sparse. We do not argue that conceptions from veterinary medicine should be used in human medicine and vice versa, but only that it could be done and that it may well be fruitful. Moreover, there are overlaps between some notions of normal and natural, and further conceptual analysis on this overlap is needed.
Modern medical care is influenced by two paradigms: 'evidence-based medicine' and 'patient-centered medicine'. In the last decade, both paradigms rapidly gained in popularity and are now both supposed to affect the process of clinical decision making during the daily practice of physicians. However, careful analysis shows that they focus on different aspects of medical care and have, in fact, little in common. Evidence-based medicine is a rather young concept that entered the scientific literature in the early 1990s. It has basically a positivistic, biomedical perspective. Its focus is on offering clinicians the best available evidence about the most adequate treatment for their patients, considering medicine merely as a cognitive-rational enterprise. In this approach the uniqueness of patients, their individual needs and preferences, and their emotional status are easily neglected as relevant factors in decision-making. Patient-centered medicine, although not a new phenomenon, has recently attracted renewed attention. It has basically a humanistic, biopsychosocial perspective, combining ethical values on 'the ideal physician', with psychotherapeutic theories on facilitating patients' disclosure of real worries, and negotiation theories on decision making. It puts a strong focus on patient participation in clinical decision making by taking into account the patients' perspective, and tuning medical care to the patients' needs and preferences. However, in this approach the ideological base is better developed than its evidence base. In modern medicine both paradigms are highly relevant, but yet seem to belong to different worlds. The challenge for the near future is to bring these separate worlds together. The aim of this paper is to give an impulse to this integration. Developments within both paradigms can benefit from interchanging ideas and principles from which eventually medical care will benefit. In this process a key role is foreseen for communication and
The 3rd Sino-Japan Nuclear Medicine Conference was hold on May 11-13, 1999 in Xi'an of China by Chinese Society of Nuclear Medicine, Japanese Society of Nuclear Medicine, Chinese Medicine Association and Japan-China Medicine Association. 62 articles were published in the proceeding of the conference. The contents of the articles include development and application of the radioisotopes (such as Tc-99, I-125, I-131, F-18, In-111, Tl-201, Ga-67, Sm-153, Re-188) and its radiopharmaceuticals, but application also include radiotherapy and diagnosis in the oncology and pathology by SPECT and PET

many physical factors degrade single photon emission computed tomography (SPECT) images both qualitatively and quantitatively. Physical properties important for the assessment of the potential of emission computed tomography implemented by collimated detector systems include sensitivity, statistical and angular sampling requirements, attenuation compensation, resolution, uniformity, and multisection design constraints. SPECT has highlighted the used to improve gamma camera performance. Flood field nonuniformity is translated into tomographic the need to improve gamma camera performance. Flood field nonuniformity is translated into tomographic images as major artifacts because it distorts the data obtained at each projection. Also, poor energy resolution translates directly into degraded spatial resolution through reduced ability to reject scattered photons on the basic of pluses height analysis. The aim of this work is study the different and most important acquisition and processing parameters, which affect the quality of the SPECT images. The present study investigates the various parameters effecting SPECT images and experimental results demonstrate that: daily uniformity checks and evaluation are essential to ensure that the SPECT system is working properly. The Core used in the reconstruction process could be correct to avoid data misalignment. 60 mumblers of views gave the best image quality, rather than 20 or 30 views. Time per view (TPV) 30 or 20 sec gave a good image quality, rather than high-resolution collimator, is recommended in order to provide good spatial resolution. On the other hand patient motion could cause serious reconstruction artifacts. A cine display is recommended to identify movement artifacts. In the case of matrix size, matrix 128x128 give the best resolution than matrix 64x64. Energy window width, 15% compared with the standard 20% improved the resolution. Butter worth filter (cut off 0.57 cyc/cm with order 6 ) give the best resolution

This study is collocated in the debate about the gender gap in Medicine giving voice to female physicians who have damaged the "glass ceiling". Our research offers a contribute to the exploration about the motivations of persistence of gender gap in Medicine despite current changes. This study is based on 21 biographical interviews to female physicians who are managers in Italian hospitals. The themes emerged by data analysis concerned the participants 'discrimination experiences in their hierarchical advancement, the evidences of a persistence of horizontal segregation in some medical specializations, the difficult to find a work-life balance and the effects of this difficult on the female physicians' health. Our research confirmed a persistence of gender gap in the medical world, which disadvantages women in their career choices and in their hierarchical advancement and which appears in the form of invisible barriers impregnated of stereotypes and prejudices that are taken for granted by many men and women, especially those who have the power; these barriers make the female doctors 'health more vulnerable to the event of work-related stress. By the dates emerged the necessity of cultural and institutional interventions, actions for deconstruction of gender stereotypes, and the necessity of intervention for a more flexible and functioning work organization that satisfies the female physicians' needs.
The aim of this review is to identify, critically evaluate, and summarize the laughter literature across a number of fields related to medicine and health care to assess to what extent laughter health-related benefits are currently supported by empirical evidence. A comprehensive laughter literature search was performed. A thorough search of the gray literature was also undertaken. A list of inclusion and exclusion criteria was identified. It was necessary to distinguish between humor and laughter to assess health-related outcomes elicited by laughter only. Thematic analysis was applied to summarize laughter health-related outcomes, relationships, and general robustness. Laughter has shown physiological, psychological, social, spiritual, and quality-of-life benefits. Adverse effects are very limited, and laughter is practically lacking in contraindications. Therapeutic efficacy of laughter is mainly derived from spontaneous laughter (triggered by external stimuli or positive emotions) and self-induced laughter (triggered by oneself at will), both occurring with or without humor. The brain is not able to distinguish between these types; therefore, it is assumed that similar benefits may be achieved with one or the other. Although there is not enough data to demonstrate that laughter is an all-around healing agent, this review concludes that there exists sufficient evidence to suggest that laughter has some positive, quantifiable effects on certain aspects of health. In this era of evidence-based medicine, it would be appropriate for laughter to be used as a complementary/alternative medicine in the prevention and treatment of illnesses, although further well-designed research is warranted.

The goal of artificial intelligence, expert systems, decision support systems and computer assisted diagnosis (CAD) in imaging is the development and implementation of software to assist in the detection and evaluation of abnormalities, to alert physicians to cognitive biases, to reduce intra and inter-observer variability and to facilitate the interpretation of studies at a faster rate and with a higher level of accuracy. These developments are needed to meet the challenges resulting from a rapid increase in the volume of diagnostic imaging studies coupled with a concurrent increase in the number and complexity of images in each patient data. The convergence of an expanding knowledge base and escalating time constraints increases the likelihood of physician errors. Errors are even more likely when physicians interpret low volume studies such as 99mTc-MAG3 diuretic scans where imagers may have had limited training or experience. Decision support systems include neural networks, case-based reasoning, expert systems and statistical systems. iRENEX (renal expert) is an expert system for diuretic renography that uses a set of rules obtained from human experts to analyze a knowledge base of both clinical parameters and quantitative parameters derived from the renogram. Initial studies have shown that the interpretations provided by iRENEX are comparable to the interpretations of a panel of experts. iRENEX provides immediate patient specific feedback at the time of scan interpretation, can be queried to provide the reasons for its conclusions and can be used as an educational tool to teach trainees to better interpret renal scans. iRENEX also has the capacity to populate a structured reporting module and generate a clear and concise impression based on the elements contained in the report; adherence to the procedural and data entry components of the structured reporting module assures and documents procedural competency. Finally, although the focus is CAD applied to

Physician scientists are seen as important in healthcare research. However, the number of physician scientists and their success in obtaining NIH funding have been declining for many years. The shortage of physician scientists in Physical Medicine and Rehabilitation is particularly severe, and can be attributed to many of the same factors that affect physician scientists in general, as well as to the lack of well developed models for research training. In 1995, the Rehabilitation Medicine Scientist Training Program (RMSTP) was funded by a K12 grant from the National Center of Medical Rehabilitation Research (NCMRR), as one strategy for increasing the number of research-productive physiatrists. The RMSTP's structure was revised in 2001 to improve the level of preparation of incoming trainees, and to provide a stronger central mentorship support network. Here we describe the original and revised structure of the RMSTP and review subjective and objective data on the productivity of the trainees who have completed the program. These data suggest that RMSTP trainees are, in general, successful in obtaining and maintaining academic faculty positions and that the productivity of the cohort trained after the revision, in particular, shows impressive growth after about 3 years of training.

Currently, post-mortem computed tomography (PMCT) has become an accessible and contemporary tool for forensic investigations. In the case of burn victims, it provides specific semiologies requiring a prudent understanding to differentiate between the normal post-mortem changes from heat-related changes. The aim of this pictorial essay is to provide to the radiologist the keys to establish complete and focused reports in cases of PMCT of burn victims. Thus, the radiologist must discern all the contextual divergences with the forensic history, and must be able to report all the relevant elements to answer to the forensic pathologist the following questions: Are there tomographic features that could help to identify the victim? Is there evidence of remains of biological fluids in liquid form available for toxicological analysis and DNA sampling? Is there another obvious cause of death than heat-related lesions, especially metallic foreign bodies of ballistic origin? Finally, what are the characteristic burn-related injuries seen on the corpse that should be sought during the autopsy? • CT is highly useful to find features permitting the identification of a severely burned body. • PMCT is a major asset in gunshot injuries to depict ballistic foreign bodies in the burned cadavers. • CT is able to recognise accessible blood for tests versus heat clot (air-crescent sign). • Heat-related fractures are easily differentiated from traumatic fractures. • Epidural collections with a subdural appearance are typical heat-related head lesions.

American internal medicine suffers a confusion of identity as we enter the 21st century. The subspecialties prosper, although unevenly, and retain varying degrees of connection to their internal medicine roots. General internal medicine, identified with primary care since the 1970s, retains an affinity for its traditional consultant-generalist ideal even as primary care further displaces that ideal. We discuss the origins and importance of the consultant-generalist ideal of internal medicine as exemplified by Osler, and its continued appeal in spite of the predominant role played by clinical science and accompanying subspecialism in determining the academic leadership of American internal medicine since the 1920s. Organizing departmental clinical work along subspecialty lines diminished the importance of the consultant-generalist ideal in academic departments of medicine after 1950. General internists, when they joined the divisions of general internal medicine that appeared in departments of medicine in the 1970s, could sometimes emulate Osler in practicing a general medicine of complexity, but often found themselves in a more limited role doing primary care. As we enter the 21st century, managed care threatens what remains of the Oslerian ideal, both in departments of medicine and in clinical practice. Twenty-first century American internists will have to adjust their conditions of work should they continue to aspire to practice Oslerian internal medicine. PMID:12950486
Medicine and management should be more closely integrated not just at the level of health policy and health services management but also in matters of professional education and training. Learning is a continuous process from entering medical school to retirement and should reflect the transition from learning shaped by the curriculum to learning driven by the needs of the qualified professional in a career service post. The senior clinician does much more than practise clinically. He or she is a leader, a manager, a resource allocator, a teacher and team player. In these roles the values and priorities of the professional and the organization will not always coincide. In postgraduate training and in continuing medical education more joint activity should be developed around 'medicine for non-medical managers' and 'management for doctors'. Much of this shared learning and development will be local and problem-based around local issues of quality, resources and priorities. However, the 'regional' postgraduate dean will play an increasingly pivotal role in maintaining the balance between the needs of the individual and the organization. To achieve this objective of closer integration postgraduate medical education funding should be brought together under a national finance levy against purchasers and allocated through devolved budgets managed by 'regional' postgraduate deans against explicit performance criteria agreed between the professional organizations, universities and health services management.

Previous analyses of the listings of trastuzumab on the Australian Pharmaceutical Benefits Scheme (PBS) and HPV vaccine on the National Immunisation Program (NIP) suggest a media influence on policy makers. We examined the timing and content of Australian newspaper reports of medicines in relation to Pharmaceutical Benefits Advisory Committee (PBAC) decisions. We identified newspaper reports (2005-2008) of medicines recommended for PBS listing in 2006-2007, analysing the content for mentions of the medicine, PBS and medicine costs to the patient and the government and counting the numbers of articles published in the six months before, the month of, and the six months after the relevant PBAC meeting. Case studies examined reporting for infliximab for Crohn's Disease, pemetrexed for mesothelioma, and ADHD (Attention Deficit Hyperactivity Disorder) medicines atomoxetine and methylphenidate. Of 79 eligible medicines, 62 had news reports. Most often reported were HPV vaccine (1230 stories), trastuzumab (410), pemetrexed (83), botulinum toxin (71), lapatinib (65), methylphenidate (57), atomoxetine (54), infliximab (49), rotavirus vaccine (45). Eighteen medicines had ≥20 news reports (total 2350 stories); nine of these cost more than AU$10,000 per course or year of treatment. For these 18 medicines, 31% of stories appeared in the six months prior to the PBAC meeting, 14% in the meeting month and 33% in the six months post-meeting. 38% of the stories had ≥3 medicine mentions, 37% referred to the PBS, 24% to cost to the patient, and 9% cost to Government.There was active patient lobby group campaigning in support of listing of infliximab and pemetrexed; the stories for ADHD were often more negative, referring to the dangers of the medicines and sometimes questioning the appropriateness of treatment and public subsidy. There was little discussion of the PBAC's evidence-based decision-making processes. While there was no general trend to increased news reporting
Personalized healthcareor what the award-winning author Donna Dickenson calls Me Medicine"is radically transforming our longstanding, one-size-fits-all" model. Technologies such as direct-to-consumer genetic testing, pharmacogenetics in cancer care, private umbilical cord blood banking, and neurocognitive enhancement claim to cater to an individual's specific biological character. In some cases, these technologies have shown powerful potential, yet in others, they have produced negligible or even negative results. Whatever is behind the rise of Me Medicine, it isn't just science. So why is Me Medicine rapidly edging out We Medicine, and how has our commitment to collective health suffered as a result? In her balanced, provocative analysis, Dickenson examines the economic and political factors fueling the Me Medicine phenomenon and explores whether it may, over time, damage our individual health as well as our collective well-being. Historically, it is the measures of We Medicine," such as vaccinatio...

In Renaissance and early modern times, the concept of imagination (Latin imaginatio) was essential for the (natural) philosophical explanation of magic processes, especially in the anthropology of Paracelsus. He assumed that imagination was a natural vital power including cosmic, mental, phychical, and physical dimensions. The Paracelsians criticized traditional humor pathology ignoring their theory of' 'natural magic'. On the other hand, they were criticized by their adversaries as charlatans practicing 'black magic'. About 1800, in between enlightenment and romanticism, the healing concept of, animal magnetism' (Mesmerism) evoked an analogous debate, whether, magnetic' phenomena originated from a real (physical) power (so-called, fluidum') or were just due to fantasy or imagination (German Einbildungskraft). At the end of the 19th century, the French internist Hippolyte Bernheim created-against the background of medical hypnosis (hypnotism') as a consequence of Mesmerism - his theory of suggestion and autosuggestion: a new paradigm of psychological respectively psychosomatic medicine, which became the basis for the concept of, placebo' in modern biomedicine. From now on, all the effects of, alternative medicine' could easily be explained by the, placebo-effect', more or less founded - at least unconsciously - on fraud.
It is worth recalling that Catholicism and Protestantism have each played an important role in the development of modern medicine. Before modern medicine become widely accepted, palliative care was addressed by Catholic abbes in Western Europe, as well as by Buddhist monks in Japan. Palliative medicine exceeds the capability of contemporary medicine in general, insofar as spirituality is an important dimension when doctors are caring for patients who may be facing death. Being aware of this problem, the author tries to elucidate the contributions of religion to medicine, with the intention of considering the future of palliative medicine in Japan.
This study aims to discuss approaches to assessing the value of medicines. Economic evaluation assesses value by means of the incremental cost-effectiveness ratio (ICER). Health is maximized by selecting medicines with increasing ICERs until the budget is exhausted. The budget size determines the value of the threshold ICER and vice versa. Alternatively, the threshold value can be inferred from pricing/reimbursement decisions, although such values vary between countries. Threshold values derived from the value-of-life literature depend on the technique used. The World Health Organization has proposed a threshold value tied to the national GDP. As decision makers may wish to consider multiple criteria, variable threshold values and weighted ICERs have been suggested. Other approaches (i.e., replacement approach, program budgeting and marginal analysis) have focused on improving resource allocation, rather than maximizing health subject to a budget constraint. Alternatively, the generalized optimization framework and multi-criteria decision analysis make it possible to consider other criteria in addition to value.

Pediatric hospital medicine (PHM) programs are mission driven, not margin driven. Very rarely do professional fee revenues exceed physician billing collections. In general, inpatient hospital care codes reimburse less than procedures, payer mix is poor, and pediatric inpatient care is inherently time-consuming. Using traditional accounting principles, almost all PHM programs will have a negative bottom line in the narrow sense of program costs and revenues generated. However, well-run PHM programs contribute positively to the bottom line of the system as a whole through the value-added services hospitalists provide and hospitalists' ability to improve overall system efficiency and productivity. This article provides an overview of the business of hospital medicine with emphasis on the basics of designing and maintaining a program that attends carefully to physician staffing (the major cost component of a program) and physician charges (the major revenue component of the program). Outside of these traditional calculations, resource stewardship is discussed as a way to reduce hospital costs in a capitated or diagnosis-related group reimbursement model and further improve profit-or at least limit losses. Shortening length of stay creates bed capacity for a program already running at capacity. The article concludes with a discussion of how hospitalists add value to the system by making other providers and other parts of the hospital more efficient and productive.

The aim of this study is to investigate the archaeological finds to enlighten the medical methods of treatments and operations applied in Balkans during Roman Period. Some independent local and regional find groups, taken from existing publications will be grouped together and a holistic point-of-view will be taken against medicine in Balkan Geography during Roman Period. Due to basic differences it contained, the data before Roman Period are excluded. Most of Greece and Aegean Islands are also excluded since the topic selected is "Medicine of Roman Period." Greece and Aegean Islands should be evaluated in another study in connection with West Anatolia which is closer than the Balkan Geography in terms of social relations. The spread of medical tools in Balkans during Roman Period is concentrated around military garrisons, and in settlements built around military pathways, and in settlements containing an amphitheater associated with gladiators. This spread is verified by the studies on Bulgaria in general. The data is also compatible with the assertion suggesting that the amount of application of pharmaceutical treatment increases when one moves away from the military centres.

Humanity is facing an increasing number of highly virulent and communicable diseases such as avian influenza. Researchers believe that avian influenza has potential to evolve into one of the deadliest pandemics. Combating these diseases requires in-depth knowledge of their epidemiology. An effective methodology for discovering epidemiological knowledge is to utilize a descriptive, evolutionary, ecological model and use bio-simulations to study and analyze it. These types of bio-simulations fall under the category of computational evolutionary methods because the individual entities participating in the simulation are permitted to evolve in a natural manner by reacting to changes in the simulated ecosystem. This work describes the application of the aforementioned methodology to discover epidemiological knowledge about avian influenza using a novel eco-modeling and bio-simulation environment called SEARUMS. The mathematical principles underlying SEARUMS, its design, and the procedure for using SEARUMS are discussed. The bio-simulations and multi-faceted case studies conducted using SEARUMS elucidate its ability to pinpoint timelines, epicenters, and socio-economic impacts of avian influenza. This knowledge is invaluable for proactive deployment of countermeasures in order to minimize negative socioeconomic impacts, combat the disease, and avert a pandemic

EGEE organized a shadowing day to spur female students to take up careers in the IT field. Eleven female staff from CERN’s IT Department were kept under close surveillance last week, shadowed by female students from the Collège du Léman International School as part of the Enabling Grids for E-sciencE project Gender Action Plan. The shadowing day was aimed at inspiring young women to think of careers in information technology, by passing on the message that careers in science are open to both men and women and can be rewarding and fun. The students were given a tour of the ATLAS physics experiment and the CERN Computer Centre, as well as the opportunity for one-to-one interaction with CERN IT staff. Traditionally, fewer women work in the IT sector; women currently represent 21% of EGEE staff. The shadowing day was held as part of the EGEE Gender Action Plan, reflecting a commitment to reducing this gender gap. Other initiatives in...
The National Magnetic Fusion Energy Computer Center (NMFECC) was established by the U.S. Department of Energy's Division of Magnetic Fusion Energy (MFE). The NMFECC headquarters is located at Lawrence Livermore National Laboratory. Its purpose is to apply large-scale computational technology and computing techniques to the problems of controlled thermonuclear research. In addition to providing cost effective computing services, the NMFECC also maintains a large collection of computer codes in mathematics, physics, and engineering that is shared by the entire MFE research community. This review provides a broad perspective of the NMFECC, and a list of available codes at the NMFECC for engineering computations is given
We all know them: the well-established cases of knowledge transfer from physics to medicine in which CERN has played an important role. From technology for PET scanners to dedicated accelerator designs for cancer therapy, we have contributed a lot over the years. But until recently, the pathway has been a little ad hoc, depending largely on enthusiastic individuals. That’s about to change. CERN’s commitment to formalising the transfer of knowledge to the field of medicine has been growing over recent years. Notable successes are the establishment of a new conference series, ICTR-PHE, that brings together medical practitioners and members of the physics community, and the establishment of cancer therapy centres like CNAO in Italy and MedAustron in Austria, built on CERN accelerator technology. These are important, but there’s still more that we can and should do. To this end, we’ve created a new Office for CERN Medical Applications, whose first head w...

To estimate the prevalence, indications, and associated factors for complementary and alternative medicine use during the last trimester of pregnancy. A questionnaire survey was conducted of women with a live birth (N=700) admitted to the postnatal unit at the Royal Aberdeen Maternity Hospital, northeast Scotland. Outcome measures included: complementary and alternative medicine used; vitamins and minerals used; reasons for complementary and alternative medicine use; independent associated factors for use; views; and experiences. Descriptive and inferential statistical analysis was performed. The response rate was 79.6% of eligible women. Two thirds of respondents (61.4%) reported using complementary and alternative medicine, excluding vitamins and minerals, during the third trimester. Respondents reported using a total of 30 different complementary and alternative medicine modalities, of which oral herbal products were the most common (38% of respondents, 40 different products). The independent associated factors for complementary and alternative medicine use identified were: complementary and alternative medicine use before pregnancy (odds ratio [OR] 4.36, 95% confidence interval [CI] 2.39-7.95, Palternative medicine use by family or friends (OR 2.36, 95% CI 1.61-3.47, Palternative medicines were safer than prescribed medicines (P=.006), less likely to be associated with side effects (P≤.001), and could interfere with conventional medicines (P≤.001). Despite the majority of respondents, and notably users, being uncertain about their safety and effectiveness, complementary and alternative medicine modalities and complementary and alternative medicine products are widely used during the third trimester of pregnancy in this study population. Although prior use was the most significant independent associated factor, the role of family and friends, rather than health professionals, in the decision to use complementary and alternative medicine may be of concern

The current species extinction crisis is being exacerbated by an increased rate of emergence of epizootic disease. Human-induced factors including habitat degradation, loss of biodiversity and wildlife population reductions resulting in reduced genetic variation are accelerating disease emergence. Novel, efficient and effective approaches are required to combat these epizootic events. Here, we present the case for the application of human precision medicine approaches to wildlife medicine in order to enhance species conservation efforts. We consider how the precision medicine revolution, coupled with the advances made in genomics, may provide a powerful and feasible approach to identifying and treating wildlife diseases in a targeted, effective and streamlined manner. A number of case studies of threatened species are presented which demonstrate the applicability of precision medicine to wildlife conservation, including sea turtles, amphibians and Tasmanian devils. These examples show how species conservation could be improved by using precision medicine techniques to determine novel treatments and management strategies for the specific medical conditions hampering efforts to restore population levels. Additionally, a precision medicine approach to wildlife health has in turn the potential to provide deeper insights into human health and the possibility of stemming and alleviating the impacts of zoonotic diseases. The integration of the currently emerging Precision Medicine Initiative with the concepts of EcoHealth (aiming for sustainable health of people, animals and ecosystems through transdisciplinary action research) and One Health (recognizing the intimate connection of humans, animal and ecosystem health and addressing a wide range of risks at the animal-human-ecosystem interface through a coordinated, collaborative, interdisciplinary approach) has great potential to deliver a deeper and broader interdisciplinary-based understanding of both wildlife and human
The contribution of pulmonary nuclear medicine was evaluated in 115 patients with interstitial pulmonary diseases (IPD). Ventilation study (V) with 81m Kr or 133 Xe, distribution of compliance in thoraco-pulmonary system (C) by 81m Kr gas bolus inhalation method, perfusion study (Q) with 99m Tc-MAA, 67 Ga scintigraphy and an assessment of pulmonary epithelial permeability with 99m Tc-DTPA aerosol were performed as nuclear medicine procedures. Pulmonary function test (%DLco, vital capacity, and functional residual capacity) and blood gas analysis were also examined. Abnormalities in V were larger than that in Q, which was high V/Q mismatch finding, in interstitial pneumonia. Correlation between V/Q mismatch and PaO 2 was, therefore, not significant. %DLco was decreased in cases with larger V/Q mismatches. 67 Ga accumulated in the early stage of interstitial pneumonia when CT or chest X-ray did not show any finding. %DLco was decreased in cases with strong accumulation of 67 Ga. 67 Ga might be useful to evaluate activity of the disease. Pulmonary epithelial permeability was assessed by 99m Tc-DTPA inhalation study. This permeability became accelerated in idiopathic interstitial fibrosis and sarcoidosis. Pulmonary epithelial permeability may be useful as an indicator for epithelial cell injury. (author)

unable to do. Hypnosis and guided imagery historically have been used in Eastern medicine but looked down upon in the Western sector. Complimentary alternative or Integrative medicine as it is now called has brought the Western world into a new means of healing as well as complimenting conventional Medicine. Hippocrates the father of modern medicine used the bark of the willow tree to treat his patients for pain or other maladies. He was aware of the healing and pain relief this bark brought to patients of his century. This was common practice yet it was centuries before The Bayer Company in Germany developed the first aspirin. The reason for the story is that Salicylates the main ingredient in non steroidal anti- inflammatory drugs i.e. aspirin is derived from the bark of the willow tree developed centuries before and used successfully. a delayed recognition of healing therapies used and proven to have positive effects for a patient borders on negligence in medicine. It is vital when something is used successfully to recognize its validity and importance and bring it to the forefront. Alternative therapies used successfully for centuries in the Eastern world are now in the Western world being used in hospitals and clinics across the country but still not at the status it deserves. Western medicine does not give it more than a complimentary status perhaps out of fear of replacing modern methods. It should be accepted and welcomed as it makes a difference and perhaps could preclude more invasive treatments in the future.These therapies including hypnosis and guided imagery are used throughout the world and are available to patients as complimentary but they need recognition and more importantly a board to regulate the practice of them as they are integrated into modern medicine. There needs to be a certification for practicing hypnosis and hypnotherapy. A board equal to the status of the State Medical Boards empowered to enforce strict adherence to the ethical and

A computer system based on the Siemens R30 process computer has been employed at the Institute of Nuclear Medicine of the Augsburg Hospital Center since early 1981. This system, including the development and testing of organ-specific evaluation programs, was used as a basis for the conception of the new computer system for the department of nuclear medicine of the Augsburg Hospital Center. The computer system was extended and installed according to this conception when the new 1400-bed hospital was opened in the 3rd phase of construction in autumn 1982. (orig.) [de

Herbal products have gained increasing popularity in the last decades, and are now broadly used to treat illness and improve health. Notwithstanding the public opinion, both, safety and efficacy, are major sources of dispute among the scientific community, mainly due to lack of (or scarcity or scattered) conclusive data linking a herbal constituent to pharmacological action in vivo, in a way that benefit overrides risk. This paper presents a methodological framework for addressing natural medicine in a systematic and holistic way with a view to providing medicinal products based on interactive chemical/herbal ingredients.
The Giornale de' letterati published in Rome from 1668 to 1681 was the first Italian scientific journal. It was meant to be the Italian version of the French Journal des Sçavans or the English Philosophical Transactions. Unlike these two, it was not backed by a formal or informal scientific institution, even if one of its editors, Giovanni Giustino Ciampini, was the founder of the Accademia Fisico-Matematica, the leading scientific academy in Rome in the second half of the XVIIth century. The paper, a preliminary step in a study on the diffusion and communication of European medical culture in Rome in this period, indexes and broadly examines the articles pertaining to medicine published in the journal.

Teaching and learning of forensic medicine and pathology in the undergraduate medical curriculum has been in decline for decades in the UK, and yet graduates are expected to be able to recognise, and protect, those who are most vulnerable in society - i.e. at risk of abuse or neglect - a matter highly relevant to the role of the forensic medical practitioner. When Cardiff University School of Medicine created a new 'learner-centred' undergraduate curriculum, championing case-based discussion in small groups, and earlier clinical contact, residual teaching on 'the pathology of trauma' disappeared. An opportunity to create a new course for the year 3 core curriculum, however, led to re-emergence of forensic medicine and pathology, with a focus on identification, and protection, of the 'vulnerable patient'. This paper describes the development process of the first two iterations of that course, and the influence of 'listening to the student voice'. Forensic medicine and pathology remain relevant in undergraduate medical education; effective, and ethical, safeguarding of the vulnerable is an essential 'core' skill of the modern medical graduate, and forensic medical practitioners can play an integral role in the preparation of medical students for their future clinical practice.

The Eastern Ghats of India is well known for its wealth of natural vegetation and Shervaroy is a major hill range of the Eastern Ghats of Tamil Nadu. Ethnomedicinal studies in the Eastern Ghats of Tamil Nadu or the Shervaroy Hills have been carried out by various researchers. However, there is not much information available on ethnoveterinary medicine in the Eastern Ghats of India. The aim of this study was to examine the potential use of folk plants as alternative medicine for cattle to cure various diseases in the Shervaroy Hills of the Eastern Ghats. Based on interactions with traditional medicine practitioners, it has been observed that a total of 21 medicinal plants belonging to 16 families are used to cure various diseases such as mastitis, enteritis, arthritis, stomatitis, salivation from the mouth, wounding, and conjunctivitis in animals. It has been observed that the traditional knowledge of ethnoveterinary medicine is now confined only among the surviving older people and a few practitioners in the tribal communities of the Shervaroy Hills. Unfortunately, no serious attempts have been made to document and preserve this immense treasure of traditional knowledge.

The use of folk medicine has been widely embraced in many developed countries under the name of traditional, complementary and alternative medicine (TCAM) and is now becoming the mainstream in the UK and the rest of Europe, as well as in North America and Australia. Diversity, easy accessibility, broad continuity, relatively low cost, base levels of technological inputs, fewer side effects, and growing economic importance are some of the positive features of folk medicine. In this framework, a critical need exists to introduce the practice of folk medicine into public healthcare if the goal of reformed access to healthcare facilities is to be achieved. The amount of information available to public health practitioners about traditional medicine concepts and the utilization of that information are inadequate and pose many problems for the delivery of primary healthcare globally. Different societies have evolved various forms of indigenous perceptions that are captured under the broad concept of folk medicine, e.g., Persian, Chinese, Grecian, and African folk medicines, which explain the lack of universally accepted definitions of terms. Thus, the exchange of information on the diverse forms of folk medicine needs to be facilitated. Various concepts of Wind are found in books on traditional medicine, and many of those go beyond the boundaries established in old manuscripts and are not easily understood. This study intends to provide information, context, and guidance for the collection of all important information on the different concepts of Wind and for their simplification. This new vision for understanding earlier Chinese medicine will benefit public health specialists, traditional and complementary medicine practitioners, and those who are interested in historical medicine by providing a theoretical basis for the traditional medicines and the acupuncture that is used to eliminate Wind in order to treat various diseases.

Progress in the foundations of mathematics has made it possible to formulate all thinkable mathematical concepts, algorithms and proofs in one language and in an impeccable way. This is not in spite of, but partially based on the famous results of Gödel and Turing. In this way statements are about mathematical objects and algorithms, proofs show the correctness of statements and computations, and computations are dealing with objects and proofs. Interactive computer systems for a full integration of defining, computing and proving are based on this. The human defines concepts, constructs algorithms and provides proofs, while the machine checks that the definitions are well formed and the proofs and computations are correct. Results formalized so far demonstrate the feasibility of this 'computer mathematics'. Also there are very good applications. The challenge is to make the systems more mathematician-friendly, by building libraries and tools. The eventual goal is to help humans to learn, develop, communicate, referee and apply mathematics.

At variance with other largely safe complementary alternative medicines like homeopathy and acupuncture, which only carry the risk of inducing patients to shun effective treatment, herbal remedies are real, albeit impure, drugs and therefore fully capable of producing undesirable consequences if misused. The advantages they offer are uncertain since genuine evidence of efficacy and effectiveness is present in only a few cases. A result of this imbalance is that studies in this field are considerably more meaningful when they deal with untoward effects than with therapeutic uses. This disproportion has suggested to us the curious similarity with the situation portrayed in the film "The Kid" where the essential task of the protagonist (Chaplin) is to repair the windows his stone-throwing child has just broken.

The oral cavity is subject to age related processes such as cellular ageing and immunosenescence. The ageing population bears an increased burden of intraoral pathology. In oral medicine, the majority of presenting patients are in their fifth to seventh decade of life. In this review, we discuss the ageing population's susceptibility to mucosal disorders and the increased prevalence of potentially malignant disorders and oral squamous cell carcinoma, as well as dermatoses including oral lichen planus and immunobullous conditions. We also address the ageing population's susceptibility to oral discomfort and explore salivary secretion, ulceration and the symptoms of oral burning. Finally, we will describe orofacial pain conditions which are more likely encountered in an older population. This update highlights clinical presentations which are more likely to be encountered in the ageing population in a general practice setting and the importance of screening both new and long-term patients. © 2015 Australian Dental Association.
Full Text Available Cloud computing represents a specific networking, in which a computer program simulates the operation of one or more server computers. In terms of copyright, all technological processes that take place within the cloud computing are covered by the notion of copying computer programs, and exclusive right of reproduction. However, this right suffers some limitations in order to allow normal use of computer program by users. Based on the fact that the cloud computing is virtualized network, the issue of normal use of the computer program requires to put all aspects of the permitted copying into the context of a specific computing environment and specific processes within the cloud. In this sense, the paper pointed out that the user of a computer program in cloud computing, needs to obtain the consent of the right holder for any act which he undertakes using the program. In other words, the copyright in the cloud computing is a full scale, and thus the freedom of contract (in the case of this particular restriction as well.

Full Text Available Diabetes mellitus (DM is a chronic metabolic disease characterized by hyperglycemy that has a significant impact for their patients. Its incidence is raising leading to an increase in the cost of the cares of the disease and of its complications. The treatment involves, besides dietary control and physical activity, the use of drugs that cause side effects to reach wanted pharmacological actions. However, products of plants are, frequently, considered less poisonous and with fewer side effects than synthetic drugs and widely used by the population. In this paper, several species of plants, used experimentally or in the popular medicine, acting by different ways to control glycemia and/or to inhibit symptoms and characteristic complications of the diabetes, they will be reviewed for evaluation of their supposed therapeutic effects.
Primary packaging guarantees the pharmaceutical quality of the medicinal preparation received by the patient. Glass bottles containing parenteral solutions for example ensure that sterility, quality and optimal stability are preserved until administration. Recent innovations in materials research has lead to improvements in parenteral infusions. Multicompartmental bags, allowing extemporaneous mixtures without opening the container, constitute an extremely beneficial advance for the patient, allowing administration of mixtures with solutions and emulsions which would be unstable if stored. Metered dose pressurized inhalers are an excellent example of drug administration devices designed specifically to ensure quality and bioavailability. These examples illustrate the important role of primary packaging and demonstrate the usefulness of research and development in this area.

Knowledge of the physiology underlying the autonomic nervous system is pivotal for understanding autonomic dysfunction in clinical practice. Autonomic dysfunction may result from primary modifications of the autonomic nervous system or be secondary to a wide range of diseases that cause severe morbidity and mortality. Together with a detailed history and physical examination, laboratory assessment of autonomic function is essential for the analysis of various clinical conditions and the establishment of effective, personalized and precise therapeutic schemes. This review summarizes the main aspects of autonomic medicine that constitute the background of cardiovascular autonomic dysfunction. Copyright © 2017 Sociedade Portuguesa de Cardiologia.

Mobile health care technology (mHealth) has the potential to improve communication and clinical information management in disasters. This study reviews the literature on health care and computing published in the past five years to determine the types and efficacy of mobile applications available to disaster medicine, along with lessons learned. Five types of applications are identified: (1) disaster scene management; (2) remote monitoring of casualties; (3) medical image transmission (teleradiology); (4) decision support applications; and (5) field hospital information technology (IT) systems. Most projects have not yet reached the deployment stage, but evaluation exercises show that mHealth should allow faster processing and transport of patients, improved accuracy of triage and better monitoring of unattended patients at a disaster scene. Deployments of teleradiology and field hospital IT systems to disaster zones suggest that mHealth can improve resource allocation and patient care. The key problems include suitability of equipment for use in disaster zones and providing sufficient training to ensure staff familiarity with complex equipment. Future research should focus on providing unbiased observations of the use of mHealth in disaster medicine.
