    The aim of the present study was to survey the validation of the Georgian version of "Oral Health Impact Profile" (OHIP). Initial testing of questionnaire showed that the all questions are understood by the patients. Survey, which was conducted with the help of the Georgian version of quality of life questionnaire, showed that received results are directed related to the progress of chronic parodontitis; during the aggravation period there is the worse quality of life than those in remission. It was confirmed that the Georgian version of the questionnaire reflects the objective side of the disease. The influence of the objective and subjective parameters on the quality of life show the average power ratios of positive correlation received by us between the quality of life and main clinical index, which is typical for parodontitis progress (CPI). During improving the clinical picture of the disease there is revealed the reduction of both, the CPI and the number of scores. Numerous studies have shown that the OHIP questionnaire was tested and accepted in different countries of the world, but until recently there were no Georgian version of the questionnaire. Questionnaire (OHIP) contains only 14 questions, which gives the patient an opportunity to quickly complete it, and the doctor - to quickly assess the results of the application. The data obtained can be used as a treatment planning, as well as during provided examination of the quality of the medical services. Based on the obtained data, we can plan not only therapeutic measures, but also to identify the need of psychological help of patients.

    The history of paediatrics and child health is increasingly recognised to be about children themselves and how they and their families cope and adapt to their medical condition rather than about medical practitioners and august institutions. This article considers two case studies, showing how two Georgian fathers cared for their children when sickness struck and their reactions when the children died. Davies (Giddy) Gilbert, FRS (1767-1840), was a member of Parliament first for Helston and later for Bodmin. (He married Ann Mary Gilbert in 1808 and formally changed his name to Gilbert; the change received royal approbation in January 1817.) Gilbert recorded the birth and development of his son Charles (1810-1813), in one of the very earliest developmental chronicles. He regularly recorded his child's progress, including height, weight, social interaction, communication skills and speech. Apparently in good health for most of his life, Charles developed an acute abdominal disorder and died unexpectedly. John Tremayne (1780-1851) was a member of Parliament for Cornwall. His son Harry (1814-1823) had increasing bilious attacks, headaches and a squint from the age of 6 years, and died despite the best medical advice available. Current medical opinion would presume an intracranial tumour. Tremayne graphically expressed his pain as he closely observed his son suffer, apparently as much from the treatments as from the disease itself. This study sheds light on clinical aspects of Georgian medical practice, the medical marketplace and the nature of relationships between these fathers and their children.

    The Armenian-Georgian Virtual Observatory (ArGVO) project is the first initiative in the world to create a regional VO infrastructure based on national VO projects and regional Grid. The Byurakan and Abastumani Astrophysical Observatories are scientific partners since 1946, after establishment of the Byurakan observatory . The Armenian VO project (ArVO) is being developed since 2005 and is a part of the International Virtual Observatory Alliance (IVOA). It is based on the Digitized First Byurakan Survey (DFBS, the digitized version of famous Markarian survey) and other Armenian archival data. Similarly, the Georgian VO will be created to serve as a research environment to utilize the digitized Georgian plate archives. Therefore, one of the main goals for creation of the regional VO is the digitization of large amounts of plates preserved at the plate stacks of these two observatories. The total amount of plates is more than 100,000 units. Observational programs of high importance have been selected and some 3000 plates will be digitized during the next two years; the priority is being defined by the usefulness of the material for future science projects, like search for new objects, optical identifications of radio, IR, and X-ray sources, study of variability and proper motions, etc. Having the digitized material in VO standards, a VO database through the regional Grid infrastructure will be active. This partnership is being carried out in the framework of the ISTC project A-1606 "Development of Armenian-Georgian Grid Infrastructure and Applications in the Fields of High Energy Physics, Astrophysics and Quantum Physics".

    2015-01-01

    This article explores the reception of some anatomical collections in Georgian and Victorian England. Both private medical museums and public anatomical museums reflected the central role played by anatomy in medical knowledge and education in the eighteenth and nineteenth centuries. However, because they were associated with death and sexuality, anatomical museums were both products of enlightenment science and potentially immoral loci likely to corrupt young and innocent women. But, as this article shows, the reasons behind the hostile receptions of some collections varied throughout the centuries, revealing in so doing the gradual professionalization of the medical field and growing monopoly of medical professionals over medical knowledge.

  6. Dependability: a challenge for electrical medical implants.

    2010-01-01

    Functional Electrical Stimulation (FES) is an attractive solution to restore some lost or failing physiological functions. Obviously, the FES system may be hazardous for patient and the reliability and dependability of the system must be maximal. Unfortunately, the present context, where the associated systems are more and more complex and their development needs very cross-disciplinary experts, is not favorable to safety. Moreover, the direct adaptation of the existing dependability techniques from domains such as space or automotive is not suitable. Firstly, this paper proposes a strategy for risk management at system level for FES medical implant. The idea is to give a uniform framework where all possible hazards are highlighted and associated consequences are minimized. Then, the paper focuses on critical parts of the FES system: analog micro-circuit which generates the electrical signal to electrode. As this micro-circuit is the closest to the human tissue, any failure might involve very critical consequences for the patient. We propose a concurrent top-down and bottom-up approach where the critical elements are highlighted and an extended risk analysis is performed.

  7. From Poison Peddlers to Civic Worthies: The Reputation of the Apothecaries in Georgian England

    PubMed Central

    Corfield, Penelope J.

    2009-01-01

    Trust is not automatically granted to providers of professional services. The doctors of Georgian England were, by later standards, deficient in medical knowhow, particularly before the mid-nineteenth-century scientific understanding of antiseptics, and much satirised. Nonetheless, the emergence of a coherent medical profession indicates that the picture was far more intricate and positive than the satirists implied. Patients sought care as well as cure; and medical practitioners had no problems in finding custom. This essay reassesses the apothecaries’ role in the slow transition whereby reputable practitioners differentiated themselves from ‘quacks’. The change was propelled by three linked processes: firstly, the intersection of expanding medical supply with insistent consumer demand, noting that demand plays a key role alongside supply; secondly, the intersection of local power-broking within Britain's growing towns with an ethos of community service, whereby apothecaries joined the ranks of ‘civic worthies’ and trusted care-givers; and, lastly, the intersection of shared medical knowledge among practitioners at all levels with the creation of a distinctive professional identity. As public trust grew, so Parliament was emboldened in 1815 to license the Apothecaries Society as the regulatory body for the medical rank-and-file, so launching the distinctive Anglo-American system of arm's-length state regulation.

    2017-01-01

    One method for three-dimensional (3D) measurement based on structured light is proposed for the medical electric endoscope in the present study. The structured light of black and white strips is generated by that the point sources illuminate the grating mask plate. Four point sources are aligned linearly by a certain space and they are lighted sequentially. Then four images of modulated fringes by the height of object with different phase shifts can be obtained. The algorithm proposed by Wang Z is employed to extract the accurate phase shift from the fringe images since the phase shift cannot be exactly set as π/2 by hardware. An experimental prototype endoscope was built according to the proposed method. One high-definition CMOS camera module developed by ourselves was used to acquire the endoscopic images and the structured light was generated by four fiber LEDs and a transmission grating with a pitch of 0.1 mm. one C# program was designed to light up LEDs in turn, acquire the phase shifted images and calculate the 3D information. The experimental results indicate that its precise of depth measurement at the working distance of 40 mm is better than 0.5 mm and its consuming time of 3D depth calculation is less than 0.5 s.

    Georgian medicine as well as the whole culture of Georgia, is one of the oldest in the world. In more than the 500 medical manuscripts preserved and since described, there are traces of Sumerian medicine. Examples of Chinese, Indian and especially Arabic medicine are also clearly seen. At the same time close relationships with Graeco-Roman medical traditions are beyond doubt. Nursing homes established by Georgian healers, many of whom were canonized by the Orthodox Church are to be found in many churches and monasteries all over the world. They gave fruitful scientific research and practical help.

    The objective of the present study was to develop the criteria for forensic-medical diagnostics of an electrical injury inflicted in the aqueous environment based on the characteristics of the electrical mark. The specific morphological features of the electrical injuries inflicted in the aqueous environment that were discovered in the materials available for the forensic medical expertise were analysed taking into consideration the results of the relevant research reported in the forensic medical literature. It was shown that an electrical injury inflicted in the aqueous environment results in the formation of an unusual mark in the form of blisters containing no watery liquid associated with electrogenic oedema in the surrounding tissues. Macroscopic and microscopic studies of the electrical mark failed to reveal the signs of grade III and IV grade thermal burning or thermally affected hair. It is concluded that the consistent characteristics of the electrical mark resulting from the injury inflicted by technical electricity in the aqueous environment include cell lengthening, blister formation inside the corneal layer, and the separation of epidermis from the skin proper.

    Aim of our research is establishing interrelation of anthropometric and psychodynamic indicators of ethnic Georgian men with normal physical development. Totally 125 men from 20 to 54 years old were observed. The were divided into 7 age groups. The anthropometric data were processed by mathematical statistics methods. For the research of character and temperament a questionnaire by Aizenk and scales of temperament by Sheldon were used. The types of mood were determined by D. Uznadze method. For determination of intellect the schemes and tests approved in England and USA were used. It was found that among ethnic Georgian men phlegmatic and sanguine persons prevail; the interconnection between of anthropometric data and temperament are 0.4-0.5. Correlation between of anthropometric data and forms of character (introversion) increases by 0.4-0.54; interrelation between the forms of intellect (mathematical, verbal) and of anthropometric data grow by 0.4-0.6; with the age interconnection between the types of mood and anthropometric data decreases by 0.1-0.2. Thus, it was established that ethnic Georgian men of normal physical development from 20 to 54 years old are mainly dolichomorphic, of sanguine temperament, extravert, they have average verbal (logical) intellect, by type of mood they are plastic-dynamic, constant-stable, with average excitement, which means they are harmonious constitutional types.

    Georgian cuisine is famous for its spices for meat dishes. Many spices are rich in polyphenols and other antioxidants that reduce the formation of carcinogenic products during thermal processing of meat and counteract its adverse health effects. In spite of the relative popularity of meat dishes, Georgia is characterized by low incidence of the colorectal cancer. We suggest that this phenomenon may be at least partially related to antioxidant-rich spices and other products of plant origin copiously used in Georgian cuisine during preparation and consumption of meat. The present study characterized the content of phenolic compounds and antioxidant capacities of hydrophilic and lipophilic fractions from commercial samples of Georgian spices. Hydrophilic antioxidant capacity and total content of phenolic compounds in the spices were closely correlated. High values of the both parameters were found in kviteli kvavili (marigold, Tagetes patula L.), kondari (summer savory, Satureja hortensis L.) and kotsakhuri (barberry, Berberis vulgaris L.), as well as in kvliavi (caraway, Carum carvi L.) and tsiteli tsitsaka (red pepper, Capsicum annuum L.). High lipophilic activity was revealed in the red pepper and especially in kviteli kvavili (marigold). The analysis of the active principles of the spices and their mode of action is in progress.

    The electrical resistivity of various tissues is known to cover a wide range of values and images of resistivity distribution within a patient should show good contrast and may prove to have some diagnostic use. Data on the internal distribution of resistivity within a patient may be obtained by applying current between electrodes attached to the patient and measuring the voltage developed across the surface of the patient. After collection of a complete set of data a tomographic image of resistivity may be constructed using a filtered back-projection algorithm. Some likely clinical uses are in the assessment of respiratory function and cardiopulmonary dynamics.

    Medical devices driven by electric power have come to be commonly used in hospitals, and rapid changes of voltage or current can easily cause them to fail. A stable and high quality power supply is indispensable in order to maintain safety in the modern clinical setting. Therefore, we investigated the quality of the power supply in a hospital and determined the tolerance of 13 pieces of medical equipment to voltage dips. The results showed little distortion of the voltage wave. However, we found an approximately 7% momentary voltage dip caused by lightening and other problems, such as 2 to 5% periodic drops in voltage and voltage wave distortions caused by incorrect grounding. In a tolerance test, the settings of some medical devices were changed at the time of automatic reboot after a disturbance. For another device, trend information was initialized.

    A novel non-contact controller of the electric bed for medical healthcare was proposed in this study. Nowadays, the electric beds are widely used for hospitals and home-care, and the conventional control method of the electric beds usually involves in the manual operation. However, it is more difficult for the disabled and bedridden patients, who might totally depend on others, to operate the conventional electric beds by themselves. Different from the current controlling method, the proposed system provides a new concept of controlling the electric bed via visual stimuli, without manual operation. The disabled patients could operate the electric bed by focusing on the control icons of a visual stimulus tablet in the proposed system. Besides, a wearable and wireless EEG acquisition module was also implemented to monitor the EEG signals of patients. The experimental results showed that the proposed system successfully measured and extracted the EEG features related to visual stimuli, and the disabled patients could operate the adjustable function of the electric bed by themselves to effectively reduce the long-term care burden.

    Field testing of medical electrical equipment remains a topic of debate amongst biomedical engineers. A questionnaire was circulated among members of the main professional body for Medical Engineering Departments in the UK and Ireland and in the Medical Physics and Engineering Mailbase Server. The aim of the questionnaire was to establish consensus on common practice on the frequency and type of safety tests carried out in the field and common sources of hazards and risk management. Twenty-six replies were received in total. A clear majority of 54% of the respondents reported that they carried out safety tests on hospital-based medical equipment on a yearly basis. For other equipment, regular tests were carried out by 58% on loan equipment and by 69% on medical electrical systems. Laboratory equipment on the other hand were not tested in 42% of the cases. Domiciliary and research equipment were only tested in 11% and 15% of the cases respectively. A clear majority of 93% said that they label equipment after tests, 34% said that they always record the actual values (as opposed to pass or fail) and 54% said they carry out functional test as part of the safety test. Although 61% of failures were attributed to the mains lead, only 50% of the respondents said that they had a management system in place for detachable mains leads.

    TASER(®) conducted electrical weapons (CEWs) have become an important law-enforcement tool. Controversial questions are often raised during discussion of some incidents in which the devices have been used. The main purpose of this paper is to point out some misconceptions about CEWs that have been published in the scientific/medical and other literature. This is a narrative review, using a multidisciplinary approach of analyzing reports from scientific/medical and other literature sources. In previous reports, durations of incapacitating effects and possible associations of CEWs with deaths-in-custody have often been overstated or exaggerated. Comparisons of CEW effects with "electrocution" are misleading. Clarification of these misconceptions may be important during policymaker decisions, practitioner operations, expert witness testimonies, and court proceedings. Despite misconceptions in the literature, CEWs can still be a valuable tool for law enforcement activities. Scientists, medical professionals, legal advisors, and investigators of police tactics should be aware of these misconceptions.

    Inherited thrombophilia means a predisposition of an individual to thrombosis caused by genetic disorders of homeostasis system. Purpose of the conducted study was to establish the role of point mutations of prothrombin (PGM) - 20210G/A; Factor V Leiden (FVL) - 1691G/A and methylenetetrahydrofolate reductase (MTHFR) - 677C/T genes, i.e. inherited thrombophilia in the pathogenesis of primary and recurrent venous thromboembolism in patients of the Georgian population. The above mentioned mutations were detected by PCR and single nucleotide primer extension reaction, followed by Enzyme Linked Immuno-Sorbent Assay (ELISA) in 93 patients with venous thromboembolism, out of which: 56 patients were diagnosed with unprovoked, primary thromboembolism confirmed by objective studies and 37 patients were diagnosed with recurrent thromboembolism. According to statistical analysis of the results, incidence of FVL mutation in the group of patients with recurrent thrombosis was significantly higher compared to patients with primary thrombosis - respectively 0.21 and 0.44 (p=0.0164<0.05). It should also be mentioned that homozygous carriage of FVL mutation was confirmed only with patients having recurrent thrombosis. Similar tendency was observed during study of prothrombin gene; however the difference was not statistically significant. Similar tendencies were not observed in case of homozygous carriage of MTHFR gene C677T mutation. Double and triple heterozygous/homozygous carriage of studied mutations (total of 20 cases) was observed in patients of both groups. Distribution of these genotypes in the recurrent thrombosis group was higher compared to patients with primary thrombosis - respectively 27% and 17.9%. Herewith, it should be mentioned that the patients with primary thrombosis were much younger than those with recurrent thrombosis and their age did not exceed 50 years. According to the results obtained by us, it is possible to consider Leiden mutation, especially its

    Vibrio parahaemolyticus is a leading cause of seafood-related gastroenteritis and is also an autochthonous member of marine and estuarine environments worldwide. One-hundred seventy strains of V. parahaemolyticus were isolated from water and plankton samples collected along the Georgian coast of the Black Sea during 28 months of sample collection. All isolated strains were tested for presence of tlh, trh, and tdh. A subset of strains were serotyped and tested for additional factors and markers of pandemicity. Twenty-six serotypes, five of which are clinically relevant, were identified. Although all 170 isolates were negative for tdh, trh, and the Kanagawa Phenomenon, 7 possessed the GS-PCR sequence and 27 the 850 bp sequence of V. parahaemolyticus pandemic strains. The V. parahaemolyticus population in the Black Sea was estimated to be genomically heterogeneous by rep-PCR and the serodiversity observed did not correlate with rep-PCR genomic diversity. Statistical modeling was used to predict presence of V. parahaemolyticus as a function of water temperature, with strongest concordance observed for Green Cape site samples (Percent of total variance = 70, P < 0.001). Results demonstrate a diverse population of V. parahaemolyticus in the Black Sea, some of which carry pandemic markers, with increased water temperature correlated to an increase in abundance of V. parahaemolyticus.

    The yeast microbiota present in wines produced by the ancient "Kakhetian" method in Georgia (EU) was studied. This technique involves the use of terracotta vessels (amphoras), during spontaneous fermentation, maceration phase and wine ageing. The analysed yeasts were collected from wines after maturation for one year in ten amphoras from a Georgian winery. The 260 isolates were all identified as Saccharomyces cerevisiae, and the majority were classified as flor yeasts by restriction analysis of ITS region. A first technological and molecular screening was used to select 70 strains for further characterization. Both genetic and metabolic characterization discriminated flor from non-flor strains. The combined results obtained by analysis of interdelta region and mtDNA-RFLP yielded 23 different biotypes; no biotype was common to flor and non-flor strains. The wines produced by flor yeasts showed a high content in acetaldehyde, acetic acid, acetoin, whereas the level of other compounds was similar to wines obtained by non-flor strains. This study represents the first report on the composition of yeast microbiota involved in the maturation of this traditional wine. These flor strains represent an interesting yeast population, in possession of peculiar characteristics allowing them to survive during wine ageing, becoming the dominant flora in the final wine.

    NNSA Administrator Thomas D'Agostino highlighted the strong U.S.-Georgian cooperation on nuclear security issues during a day-long visit to the Republic of Georgia in mid-June. He briefed the media at availability at the Tbilisi airport. In April 2009, President Obama outlined an ambitious agenda to secure vulnerable nuclear material around the world within four years, calling the danger of a terrorist acquiring nuclear weapons "the most immediate and extreme threat to global security." In this year's State of the Union, he called the threat of nuclear weapons, "the greatest danger to the American people." In order to meet that challenge, the President's FY2011 Budget Request includes close to $2.7 billion for the National Nuclear Security Administration's Defense Nuclear Nonproliferation program -- an increase of 25.7 percent over FY2010. Included in that request is NNSA's Second Line of Defense (SLD) program, which works around the world to strengthen the capability of foreign governments to deter, detect, and interdict illicit trafficking in nuclear and other radioactive materials across international borders and through the global maritime shipping system.

    Background Secondhand smoke, which is also referred to as environmental tobacco smoke and passive smoke, is a known human carcinogen. Secondhand smoke also causes disease and premature death in nonsmoking adults and children. Methods We summarize studies of secondhand smoke in public places before and after smoking bans, as well as studies of cardiovascular and respiratory disease before and after such bans. Results To protect the public from the harmful effects of secondhand smoke, smoke-free legislation is an effective public health measure. Smoking bans in public places, which have been implemented in many jurisdictions across the U.S. and in other countries, have the potential to influence social norms and reduce smoking behavior. Conclusions Through legislative smoking bans for reducing secondhand smoke exposure and smoking prevalence, opportunities exist to protect the health of Georgians and other Americans and to reduce health care costs. These opportunities include increasing the comprehensiveness of smoking bans in public places and ensuring adequate funding to quit line services. PMID:26345719

    Association analysis of data on benthic macroinvertebrates in 257 samples from Georgian Bay, followed by discriminant analysis of water and sediment characteristics, facilitated a quantitative description of trophic variability within a relatively unpolluted system. Discriminating variables were bottom water temperature, water pH and Ca, sediment organic matter, sand, silt, clay, total P, Zn, Pb, and Hg. Four discriminating functions, accounting for 86% of variance, indicated the importance of temperature, concentrations of organic matter and silt, water pH and Ca. Associations which occurred at cooler temperatures consisted of Pontoporeia hoyi with dominant oligochaetes and chironomids generally determined by sediment richness. These associations were P. hoyi - Limnodrilus hoffmeisteri - Chironomus spp, and Procladius spp. at highest sediment richness, P. hoyi - Spirosperma ferox - Micropsectra spp, at intermediate richness and P. hoyi - Stylodrilus heringianus - Heterotrissocladius sp. at lowest richness. Associations in warmer waters consisted of a Chironomus spp. - Chaoborus spp. association in richer sediments and an association of Caecidotea racovitzae and Amnicola spp. at lower sediment richness. A Hexagenia limbata - Hyalella azteca association occurred over a broad range in concentrations of organic matter and silt, but, in terms of sediment texture represented by sand content, this association was intermediate between the other two groups in warmer waters. Finally, a Zalutschia zalutschia zalutschicola - Chaoborus spp. association was related to water pH and Ca in discriminant analysis. 33 references, 4 figures, 4 tables.

  17. The 'electric stroke' and the 'electric spark': anatomists and eroticism at George Baker's electric eel exhibition in 1776 and 1777.

    In 1776 and 1777 five living electric eels exhibited in London became a sensational spectacle that appealed to anatomists, electricians and connoisseurs of erotica. George Baker's exhibition made visible the 'electric spark' of the electrical eel and a series of experiments were both witnessed by and participated in by members of the Royal Society and the metropolitan elite. Some participants even grasped the eels firmly in their hands and felt the 'electric stroke' of the eel in addition to observing the spark. In their observation of the electric eel some of these spectators transposed the vivid electric spark from the sphere of electricians and anatomists into that of satirical and erotic literature. Here the erotic electric eel proliferated in the literature and the eel took on quite different connotations that nonetheless were reliant on readers knowledge and experience of the exhibition, experiments and the preoccupations of anatomists. George Baker's electric eel exhibition of 1776 and 1777 is then instructive in exploring the production and circulation of knowledge in Georgian Britain. The story of the electric eel in Georgian culture charts the creation of the electric spark and stroke as objects of observation and encounter, their exhibitionary context, and finally their divergent meanings as the electric eel became erotically charged for a metropolitan masculine elite.

    To establish temperament and forms of character and graphical image, we have studied 120 Georgian women of normal physical development, who were divided by 4 age groups with 5 years intervals. To establish temperament and forms of character we used Eysenck's questionnaire (57 questions) and Sheldon's scale of temperament. The material was worked out by the recognized methods of mathematical psychology. It was stated that Georgian women of young age (20-40 years old) are of sanguine temperament, by character extraverts, which means that they are strong, moving, balanced, stable.

    We used a GIS-based approach to examine the influence of road density and physical watershed features (watershed size, wetland cover, and bedrock type) on water quality in coastal marshes of Georgian Bay, Ontario. We created a GIS that included landscape information and water-quality data from a 9-year synoptic survey of 105 coastal marshes covering 28 quaternary watersheds. Multiple regressions and partial correlations were used to discern confounding effects of human-induced (road density) versus natural physical watershed determinants of water quality. Road density was the dominant factor influencing many water quality variables, showing positive correlations with specific conductivity (COND), total suspended solids (TSS), and inorganic suspended solids (ISS) and a negative correlation with overall Water Quality Index scores. Road density also showed positive correlations with total nitrate nitrogen (TNN) and total phosphorus (TP). By comparison, larger watershed area was the main factor leading to elevated TP concentrations. The proportion of the watershed occupied by wetlands explained the largest amount of variation in TNN concentrations (negative correlation) and was also negatively correlated with COND and positively correlated with TSS and ISS when we controlled for road density. Bedrock type did not have a significant effect in any of the models. Our findings suggest that road density is currently the overriding factor governing water quality of coastal marshes in Georgian Bay during the summer low-flow period. We recommend that natural variation in physical watershed characteristics be considered when developing water quality standards and management practices for freshwater coastal areas.

    Epidemiological studies in high income countries suggested that a big proportion of the population in Europe and America report adverse reactions to food. Self-reported prevalence of food allergy varied from 1.2% to 17% for milk, 0.2% to 7% for egg, 0% to 2% for peanuts and fish, 0% to 10% for shellfish, and 3% to 35% for any food. The aim of our study was to report the prevalence of self-reported food allergy in the different age groups of Georgian population and to reveal the most common self-reported food allergens. ISAAC phase III study methodology and questionnaires were used for data collection. Questions about food allergy were added to the survey and involved questions about self-reported food allergy. 6-7 years old 6140 children (response rate-94,5%) and 13-14 years old 5373 adolescents (response rate-86,9%) from two locations of Georgia, Tbilisi and Kutaisi were surveyed. 500 randomly assessed adults from Tbilisi aged 18 years and older were added later (response rate-97,6%). Findings revealed that self-reported food allergy among 6-7 years old age group and 13-14 years old age were almost the same (15,7% and 15,9% correspondingly) and slightly lower in adult population - 13,9%. Study revealed, that hen's egg was the commonest implicated food for 6-7 years age group, hazel nut - for 13-14 years old age group followed by hen's egg. Walnut and hazel nut were most reported foods for adult population. The findings also revealed that food allergy is one of the most important risk factor for symptoms associated with asthma (OR-3,05; 95%CI 2.50-3.74), rhinoconjunctivitis (OR-2,85; 95%CI 2.24-3.64) and eczema (OR-5,42; 95%CI 4.08-7.18) in childhood. The data has provided the first epidemiological information related to food allergy among children and adults in Georgia. Results should serve as baseline information for food allergy screening, diagnosis and treatment. Our findings can also inform the public health officials on the disease burden and may offer some

    In Georgia, one of the most ancient vine-growing environment, the homemade production of wine is still very popular in every rural family and spontaneous fermentation of must, without addition of chemical preservatives, is the norm. The present work investigated the yeast biodiversity in five Georgian areas (Guria, Imereti, Kakheti, Kartli, Ratcha-Lechkhumi) sampling grapes and wines from 22 different native cultivars, in 26 vineyards and 19 family cellars. One hundred and eighty-two isolates were ascribed to 15 different species by PCR-ITS and RFLP, and partial sequencing of D1/D2 domain 26S rDNA gene. Metschnikowia pulcherrima (F’ = 0.56, I’ = 0.32), Hanseniaspora guilliermondii (F’ = 0.49, I’ = 0.27), and Cryptococcus flavescens (F’ = 0.31, I’ = 0.11) were the dominant yeasts found on grapes, whereas Saccharomyces cerevisiae showed the highest prevalence into wine samples. Seventy four isolates with fermentative potential were screened for oenological traits such as ethanol production, resistance to SO2, and acetic acid, glycerol and H2S production. Three yeast strains (Kluyveromyces marxianus UMY207, S. cerevisiae UMY255, Torulaspora delbrueckii UMY196) were selected and separately inoculated in vinifications experiments at a Georgian cellar. Musts were prepared from healthy grapes of local varieties, Goruli Mtsvane (white berry cultivar) and Saperavi (black berry cultivar). Physical (°Brix) and microbial analyses (plate counts) were performed to monitor the fermentative process. The isolation of indigenous S. cerevisiae yeasts beyond the inoculated strains indicated that a co-presence occurred during the vinification tests. Results from quantitative GC-FID analysis of volatile compounds revealed that the highest amount of fermentation flavors, such as 4-ethoxy-4-oxobutanoic acid (monoethyl succinate), 2-methylpropan-1-ol, ethyl 2-hydroxypropanoate, and 2-phenylethanol, were significantly more produced in fermentation conducted in Saperavi variety

    The first electric projecting microscope and the first published photomicrographs harnessed recent technological developments to provide improved methods of medical illustration for educational purposes. Both projects were the work of two Frenchmen. The impetus came from the microscopist Dr Alfred Donné (1801-78), discoverer of trichomonas vaginalis and leukaemia. Implementation was primarily by his medical-student assistant, Léon Foucault (1819-68), who later gained fame as a physicist, especially with his pendulum demonstration of the Earth's rotation.

    Benjamin Franklin had at least two accidents that resulted in electricity passing through his brain. In addition, he witnessed a patient's similar accident and performed an experiment that showed how humans could endure shocks to the head without serious ill effects, other than amnesia. Jan Ingenhousz, Franklin's Dutch-born medical correspondent better known for his discovery of photosynthesis, also had a serious accident that sent electricity though his head and, in a letter to Franklin, he described how he felt unusually elated the next day. During the 1780s, Franklin and Ingenhousz encouraged leading French and English electrical "operators" to try shocking the heads of melancholic and other deranged patients in their wards. Although they did not state that they were responding to Ingenhousz's and Franklin's suggestions, Birch, Aldini, and Gale soon did precisely what Ingenhousz and Franklin had suggested. These practitioners did not appear to induce convulsions in their mentally ill patients, but they still reported notable successes.

Emergent coronary angiography was performed and revealed occlusion in segment 7, so a stent was implanted. Lidocaine, carvedilol, amiodarone, magnesium, and nifekalant were administered successively because non-sustained ventricular tachycardia (NSVT) frequently appeared like an electrical storm. After nifekalant administration, QTc was significantly prolonged and torsades de pointes was induced. Overdrive pacing was performed and finally the NSVT was completely controlled. If fatal arrhythmias such as NSVT show resistance to medication, overdrive pacing should be considered to stabilize the arrhythmia associated with acute coronary syndrome.

    In 1950 physicians at Tulane University School of Medicine began a program of research on the use of electrical brain stimulation that would span three decades and involve approximately 100 patients. Initially, electrical brain stimulation was used to treat of schizophrenia, but later it was applied to a variety of other conditions. Throughout its history the Tulane research was well publicized in both the professional and lay literature, and for almost twenty years, with rare exception, these accounts were laudatory. However, in the early 1970s this work began to draw sharp public criticism. Despite its public and controversial nature, the Tulane electrical brain stimulation program has received relatively little attention from historians. This review recounts the history of the Tulane program with particular emphasis on the ethical propriety of the work. Factors that shaped the historical context in which the Tulane experiments were conducted are discussed.

    Hermetic electrical feedthroughs are essential for safe and functional active implantable biomedical devices and for a wide range of other applications such as batteries, supercapacitors, OLEDs and solar cells. Ceramics and metals have previously been the materials of choice for encapsulations, while polymers have advantages of ease of mass production and end user compatibility. We demonstrate a laser sealing technology that gives hermetic, mechanically strong feedthroughs with low electrical resistance in a polyetheretherketone (PEEK) encapsulation. The conductive pathways are wires and sputtered thin films. The water vapor transmission rate through the fabricated encapsulations is comparable to that of PEEK itself.

The aim of the study was to determine the incidence, etiology and main risk factors of nosocomial infections (NI) following cardiac surgery in congenital heart diseases population. Retrospective case study was conducted. 387 patients with congenital heart disease (CHD), who underwent cardiac surgery from January 2007 to December 2008 were studied. The age of the most patients varied between 1 day to 15 years, 73 patients (18,8%) were older than 15 years. All 387 patients underwent cardiac surgery. The rate of NI was 16%. The most common infections were bloodstream infections (BSI) (7,75%) and respiratory tract infections (7%) respectively. The rate of NI was higher in patients under 1 year of age, after urgent surgery and urgent reoperation, long cardiopulmonary bypass (CPB) and aortic cross-clamp time, also in patients with prolonged mechanical ventilation, massive haemotransfusion, with open heart bone after surgery, reintubation, hospitalization in another hospital during last three month. It was concluded that the most common nosocomial infection after cardiac surgery congenital heart diseases in Georgian population was blood stream infection. The main risk factors of NI in the same setting were age under 1 year, urgent surgery, urgent reoperation, long CPB and aortic cross-clamp time, long duration of mechanical ventilation, massive haemotransfusion, open heart bone after surgery, reintubation, hospitalization in another hospital during last three month.

National Hospital Organization (NHO) has been promoting the project and introduced EMR since 2004. NHO has 143 hospitals, 51 hospitals offer acute-phase medical care services, the other 92 hospitals offer medical services mainly for chronic patients. We conducted three kinds of investigations, questionnaire survey, checking the homepage information of the hospitals and analyzing the financial statements of each NHO hospital. In this financial analysis, we applied new indicators which have been developed based on personnel costs. In 2011, there are 44 hospitals which have introduced EMR. In our result, the hospital with EMR performed more investment of equipment/capital than personnel expenses. So, there is no advantage of EMR on the financial efficacy.

    Improvements in medical care during the last two decades have resulted in the survival of an ever-increasing group of patients with severe neuro-muscular disabilities who otherwise would have succumbed to their diseases or injuries. This has created a sizeable population of severely paralyzed persons totally dependent upon society for care. It has been estimated that this population may grow beyond 5,000,000 persons by 1980. A rather fortunate confluence of complementing technologies and surgical techniques offer promise of solving this growing socially significant problem.

For this reason we have investigated 100 accelerants -- 45 girls and 55 boys. On the basis of our study we have shown that correlations between subspecies of temperament and anthropometrical signs in accelerant women and men are equal or lower among men. From the point of view of character form -- these data in women are comparatively high, and correlation of intellect and types of mood and anthropometric signs are equal. In comparison with the men of normal development, in accelerant men are noticed law interconnection between anthropometrical and psychodynamic data except subspecies of intellect, which is equal in every case. Connection between the types of mood and anthropometric data are moderate (in the limits 0.3-0.4). Men accelerants (Georgians) are brachymorphic somatotypes; they are distinguished by phlegmatic temperament, introversion, middle logic intellect, conflict -- statistic mood; according to the mood they are harmonic-dynamic constitutional types.

    Duration of treatment of venous thromboembolism (VTE) and prevention of its recurrence represent significant problems of contemporary medicine, as the basic method of treatment - anticoagulation is frequently complicated by hemorrhage. Therefore, its duration is strictly defined and depends on existence of risk factors related to recurrence of thrombosis. Purpose of the conducted study was to establish the role of point mutations of prothrombin (PHG) - 20210G/A; Factor V Leiden (FVL) - 1691G/A and methylenetetrahydrofolate reductase (MTHFR) - 677C/T genes, i.e. inherited thrombophilia in the pathogenesis of proximal and distal lower extremity deep vein thrombosis in patients of the Georgian population, as in case of proximal thrombosis there is a higher risk of recurrent thrombosis. The above mutations were detected by PCR and single nucleotide primer extension reaction, followed by Enzyme Linked Immuno-Sorbent Assay (ELISA) in 61 patients with venous thromboembolism of various localizations, out of which: 49 patients were diagnosed with unprovoked proximal thromboembolism confirmed by objective studies and 12 patients were diagnosed with distal thromboembolism. The difference between the groups was evaluated by F (Fisher) precise criterion. According to statistical analysis of the results, incidence of FVL mutation in the group of patients with proximal thrombosis was significantly higher compared to patients with distal thrombosis 0.43 and 0.08 (p=0.0256), respectively. Similar tendencies were observed in case of carriage of prothrombin gene and MTHFR gene mutations, as their presence was higher in the group of patients having proximal thrombosis than in patients with distal thrombosis, however, this difference was not found to be statistically significant. It should be particularly mentioned that double or triple heterozygous or homozygous carriage of studied mutations with various options was confirmed in 15 of 61 patients and the above genotypes were observed

In this context arises the problem of structuring and classifying documents containing all the history of medical services provided. The present work introduces the instrument for classification of medical records based on the Georgian language. It is the first attempt of such classification of the Georgian language based medical records. On the whole 24.855 examination records have been studied. The documents were classified into three main groups (ultrasonography, endoscopy, and X-ray) and 13 subgroups using two well-known methods: Support Vector Machine (SVM) and K-Nearest Neighbor (KNN). The results obtained demonstrated that both machine learning methods performed successfully, with a little supremacy of SVM. In the process of classification a “shrink” method, based on features selection, was introduced and applied. At the first stage of classification the results of the “shrink” case were better; however, on the second stage of classification into subclasses 23% of all documents could not be linked to only one definite individual subclass (liver or binary system) due to common features characterizing these subclasses. The overall results of the study were successful. PMID:27668260

    This descriptive study examined characteristics of older Georgians receiving Older Americans Act Nutrition Program Services and other home- and community-based services (HCBS) using state aging administrative data (N = 31,341, mean age: 76.6 ± 9.2 y, 71.2% female, 52.3% White). Home-delivered meals (HDM) was used most frequently. The characteristics of older Georgian HCBS participants varied by the type and number of HCBS received. Those receiving HDM and other in-home and caregiving services were more likely to show poorer sociodemographic, economic, and functional characteristics, and food insecurity. Those receiving multiple HCBS were most vulnerable, but showed lower level of food insecurity than those receiving single HCBS, suggesting potential combined benefits of receiving multiple programs. This study underscores the importance of documenting dynamic needs for HCBS, especially HDM, among vulnerable older adults as part of standard administrative process to identify those at high risk of institutionalization, optimize HCBS delivery and coordination, and maximize HCBS benefits.

    Objective To examine whether older age was associated with lower health-related quality of life (HRQOL) among patients with systemic lupus erythematosus (SLE) and whether differential disease-related damage and activity explained these associations. Methods We used cross-sectional data on 684 patients with SLE aged ≥20 years from the Georgians Organized Against Lupus cohort to estimate the associations between age (categorised as 20–39, 40–59 and ≥60 years) and HRQOL (Short Form-12 norm-based domain and physical component summary (PCS) and mental component summary (MCS) scores), using multivariable linear regression. We then examined the effect of disease-related damage and activity on these associations. Results The mean age of the cohort was 48.2±13.1 years (range, 20–88 years), with 28.0%, 52.9% and 19.1% of participants being aged 20–39, 40–59 and ≥60 years, respectively; 79.0% were African-American and 93.7% were female. The mean PCS score was 39.3 (41.8, 38.7 and 37.4 among those aged 20–39, 40–59 and ≥60 years, respectively), while the mean MCS score was 44.3 (44.2, 43.8 and 46.1, respectively). In general, lower physical but not mental HRQOL scores were associated with older age. With adjustment, older ages (40–59 and ≥60, respectively, vs 20–39) remained associated (β (95% CI)) with lower PCS (−2.53 (−4.58 to −0.67) and −3.57 (−6.19 to −0.96)) but not MCS (0.47 (−1.46 to 2.41) and 1.20 (−1.52 to 3.92)) scores. Associations of age with HRQOL domain and summary scores were not substantially changed by further adjustment for disease-related damage and/or activity. Conclusions Nearly one in five participants in this large, predominantly African-American cohort of patients with SLE was at least 60 years old. The associations of older age with lower physical, but not mental, HRQOL were independent of accumulated SLE damage and current SLE activity. The results suggest that studies of important geriatric

    Students in developing countries interested in STEM disciplines (science, technology, engineering & math) often choose majors that will improve their job opportunities in their home country when they graduate, e.g. engineering or medicine. Geoscience might be chosen as a sub-discipline of civil engineering, but rarely as a primary major unless there are local economic natural resources. The Institute of International Education administers the ExxonMobil Middle East and North Africa region scholars program designed to develop skilled students with a focus on geoscience and to build relationships with academic leaders by offering select faculty the opportunity to participation in the AGU fall meeting. At the Jordan University of Science and Technology (JUST), research in electrical engineering applied to medicine has potential links to geosciences. In geophysics, neural wavelet analysis (NWA) is commonly used to process complex seismic signals, e.g. for interpreting lithology or identifying hydrocarbons. In this study, NWA was used to characterize cardiac arrhythmias. A classification scheme was developed in which a neural network is used to identify three types of arrhythmia by distinct frequency bands. The performance of this scheme was tested using patient records from two electrocardiography (ECG) databases. These records contain normal ECG signals, as well as abnormal signals from atrial fibrillation (AF), ventricular tachycardia (VT) and ventricular fibrillation (VF) arrhythmias. The continuous wavelet transform is applied over frequencies of 0-50 Hz for times of 0-2s. For a normal ECG, the results show that the strongest signal is in a frequency range of 4-10 Hz. For AF, a low frequency ECG signal in the range of 0-5 Hz extends over the whole time domain. For VT, the low frequency spectrum is in the range of 2-10 Hz, appearing as three distinct bands. For VF, a continuous band in the range of 2-10 Hz extends over the whole time domain. The classification of

    Technologic innovations enable management of medical equipment and power supply systems, with improvements that can affect the technical aspects, economics, and quality of medical service. Herein are outlined some technical guidelines, proposed by Istituto Superiore per la Prevenzione e la Sicurezza del Lavoro, for increasing the effectiveness of the power supply system and the safety of patients and surgeons in the operating room, with particular focus on transplantation. The dependence of diagnoses and therapies on operation of the electrical equipment can potentially cause great risk to patients. Moreover, it is possible that faulty electrical equipment could produce current that may flow through the patient. Because patients are particularly vulnerable when their natural protection is considerably decreased, as during transplantation or other surgery, power supply systems must operate with a high degree of reliability and quality to prevent risk, and must be designed to reduce hazards from direct and indirect contact. Reliability of the power supply system is closely related to the quality of the project, choice of materials, and management of the system (eg, quality and frequency of servicing). Among the proposed guidelines, other than normal referencing, are (1) adoption of a monitoring system to improve the quality of the electrical parameters in the operating room, (2) institution of emergency procedures for management of electrical faults, (3) a procedure for management of fires in the operating room, (4) and maintenance interventions and inspections of medical devices to maintain minimal requirements of safety and performance.

    Quiet, clean, and efficient, electric vehicles (EVs) may someday become a practical mode of transportation for the general public. Electric vehicles can provide many advantages for the nation's environment and energy supply because they run on electricity, which can be produced from many sources of energy such as coal, natural gas, uranium, and hydropower. These vehicles offer fuel versatility to the transportation sector, which depends almost solely on oil for its energy needs. Electric vehicles are any mode of transportation operated by a motor that receives electricity from a battery or fuel cell. EVs come in all shapes and sizes and may be used for different tasks. Some EVs are small and simple, such as golf carts and electric wheel chairs. Others are larger and more complex, such as automobile and vans. Some EVs, such as fork lifts, are used in industries. In this fact sheet, we will discuss mostly automobiles and vans. There are also variations on electric vehicles, such as hybrid vehicles and solar-powered vehicles. Hybrid vehicles use electricity as their primary source of energy, however, they also use a backup source of energy, such as gasoline, methanol or ethanol. Solar-powered vehicles are electric vehicles that use photovoltaic cells (cells that convert solar energy to electricity) rather than utility-supplied electricity to recharge the batteries. These concepts are discussed.

    Electric propulsion (EP) is an attractive option for unmanned orbital transfer vehicles (OTV's). Vehicles with solar electric propulsion (SEP) could be used routinely to transport cargo between nodes in Earth, lunar, and Mars orbit. Electric propulsion systems are low-thrust, high-specific-impulse systems with fuel efficiencies 2 to 10 times the efficiencies of systems using chemical propellants. The payoff for this performance can be high, since a principal cost for a space transportation system is that of launching to low Earth orbit (LEO) the propellant required for operations between LEO and other nodes. Several aspects of electric propulsion, including candidate systems and the impact of using nonterrestrial materials, are discussed.

    2012-01-01

    Optoelectronic tweezers (OET) allows the spatial patterning of electric fields through selected illumination of a photoconductive surface. This enables the manipulation of micro particles and cells by creating non-uniform electrical fields that then produce dielectrophoretic (DEP) forces. The DEP responses of cells differ and can produce negative or positive (repelled or attracted to areas of high electric field) forces. Therefore OET can be used to manipulate individual cells and separate different cell types from each other. Thus OET has many applications for medical diagnostics, demonstrated here with work towards diagnosing Human African Trypanosomiasis, also known as sleeping sickness.

  1. Electrically Conductive Anodized Aluminum Surfaces

    NASA Technical Reports Server (NTRS)

    Nguyen, Trung Hung

    2006-01-01

    Anodized aluminum components can be treated to make them sufficiently electrically conductive to suppress discharges of static electricity. The treatment was conceived as a means of preventing static electric discharges on exterior satin-anodized aluminum (SAA) surfaces of spacecraft without adversely affecting the thermal-control/optical properties of the SAA and without need to apply electrically conductive paints, which eventually peel off in the harsh environment of outer space. The treatment can also be used to impart electrical conductivity to anodized housings of computers, medical electronic instruments, telephoneexchange equipment, and other terrestrial electronic equipment vulnerable to electrostatic discharge. The electrical resistivity of a typical anodized aluminum surface layer lies between 10(exp 11) and 10(exp 13) Omega-cm. To suppress electrostatic discharge, it is necessary to reduce the electrical resistivity significantly - preferably to < or = 10(exp 9) Omega-cm. The present treatment does this. The treatment is a direct electrodeposition process in which the outer anodized surface becomes covered and the pores in the surface filled with a transparent, electrically conductive metal oxide nanocomposite. Filling the pores with the nanocomposite reduces the transverse electrical resistivity and, in the original intended outer-space application, the exterior covering portion of the nanocomposite would afford the requisite electrical contact with the outer-space plasma. The electrical resistivity of the nanocomposite can be tailored to a value between 10(exp 7) and 10(exp 12) Omega-cm. Unlike electrically conductive paint, the nanocomposite becomes an integral part of the anodized aluminum substrate, without need for adhesive bonding material and without risk of subsequent peeling. The electrodeposition process is compatible with commercial anodizing production lines. At present, the electronics industry uses expensive, exotic

    Medical acoustics can be subdivided into diagnostics and therapy. Diagnostics are further separated into auditory and ultrasonic methods, and both employ low amplitudes. Therapy (excluding medical advice) uses ultrasound for heating, cooking, permeablizing, activating and fracturing tissues and structures within the body, usually at much higher amplitudes than in diagnostics. Because ultrasound is a wave, linear wave physics are generally applicable, but recently nonlinear effects have become more important, even in low-intensity diagnostic applications.

    The Medical Renaissance started as the regular Renaissance did in the early 1400s and ended in the late 1600s. During this time great medical personalities and scholar humanists made unique advances to medicine and surgery. Linacre, Erasmus, Leonicello and Sylvius will be considered first, because they fit the early classic Renaissance period. Andreas Vesalius and Ambroise Paré followed thereafter, making outstanding anatomical contributions with the publication of the "Human Factory" (1543) by Vesalius, and describing unique surgical developments with the publication of the "The Apologie and Treatise of Ambroise Paré." At the end of the Renaissance and beginning of the New Science, William Harvey, noted British medical doctor and cardiovascular researcher, discovered the general circulation. He published his findings in "The Motu Cordis" in 1628 (Figure 1). The Medical Renaissance, in summary, included a great number of accomplished physicians and surgeons who made especial contributions to human anatomy; Vesalius assembled detailed anatomical information; Paré advanced surgical techniques; and Harvey, a medical genius, detailed the circulatory anatomy and physiology.

    2009-01-01

    For more than two decades, Biotechnology and Bioengineering has documented research focused on natural and engineered microbial biofilms within aquatic and subterranean ecosystems, wastewater and waste-gas treatment systems, marine vessels and structures, and industrial bioprocesses. Compared to suspended culture systems, intentionally engineered biofilms are heterogeneous reaction systems that can increase reactor productivity, system stability, and provide inherent cell: product separation. Unwanted biofilms can create enormous increases in fluid frictional resistances, unacceptable reductions in heat transfer efficiency, product contamination, enhanced material deterioration, and accelerated corrosion. Missing from B&B has been an equivalent research dialogue regarding the basic molecular microbiology, immunology, and biotechnological aspects of medical biofilms. Presented here are the current problems related to medical biofilms; current concepts of biofilm formation, persistence, and interactions with the host immune system; and emerging technologies for controlling medical biofilms.

    The report reviews planned and ongoing research on biological and health effects of 50- and 60-Hz electric and magnetic fields. The purpose of the report was to review results from research since May 1989 to determine new significant findings regarding potential human health impacts from electric-power frequency fields at levels expected from transmission and distribution sources. Information in the report came from a variety of sources (scientific meetings, sponsors of directed site visits and project reviews, International Data Base of ongoing and planned research on electric and magnetic fields) and may not appear in the scientific literature for several years. Information is presented on 120 ongoing and planned research projects throughout the world, of which many are focused in 4 major areas: cancer, reproduction and development, neuroendocrine system and mechanisms of interaction at the cellular and subcellular levels. There are 25 ongoing epidemiology studies, of which 21 are concerned with cancer and 4 with reproduction and development. Results from ongoing epidemiology studies dealing with cancer in which data are available support the results of many of the earlier studies in which there is an association between exposure to electric and magnetic fields and the incidence of cancer, particularly of the hematopoetic system and nervous system.

    2013-01-01

    Glaucoma is a common eye condition that affects millions of individuals worldwide, making it the second-leading cause of blindness. Because glaucoma is associated with increased IOP level, the primary goal in treatment of glaucoma includes lowering IOP to prevent further progression of the disease. While various surgical interventions exist, medical therapy is currently the first line of treatment. Medical treatment of glaucoma includes topical beta-blockers, alpha-2 agonists, prostaglandins, parasympathomimetics and CAIs. Anti-glaucoma agents help reduce IOP by affecting the production of aqueous humor or increasing the outflow of aqueous through the trabecular or uveoscleral pathway. Choosing an appropriate medical regimen can be challenging and various factors such as efficacy, safety, cost and patient compliance must be considered. First-line treatment is often topical beta-blockers or prostaglandin analogs. However, beta-blocking agents can be associated with systemic side effects and need to be used cautiously in patients with serious concomitant cardiopulmonary disease. Alpha-2 agonists and parasympathomimetics are often considered second- or third-line treatment options but good adjunctive agents. Oral CAIs are often indicated for patients with elevated IOP in an acute setting or for patients resistant to other glaucoma medications and patients who are not good surgical candidates.

    Hippocrates already noted that geographical factors such as climate, relief, geology but also settlement patterns had influenced the distribution of diseases. The task of medical geography is to investigate the associations between geographical factors and diseases. Thereby, geographic techniques and concepts are applied on health problems. Of particular importance is the mapping of diseases whose causes are environmental-related. In addition, epidemiological, ecological but also social scientific studies play an important part in the investigation of the associations between geographical factors and diseases. In order to understand the associations between the spatial distribution of diseases and environmental exposures, geographic information systems as well as statistical analyses have recently become more important. Some authors regard medical geography merely as supporting discipline of medicine. Nevertheless, as men and environment future and as they play an important part in the diffusion of diseases being regarded as defeated, medical geography will play an important part concerning medical questions. Especially travel medicine will rely on geographic knowledge, if a patient has to be consulted who plans to travel to an unknown country of which knowledge on the geographical distribution and ecology of diseases will be necessary.

    2008-11-01

    Searches of the literature or Internet using the term "medical tourism" produce two sets of articles: travel for the purpose of delivering health care or travel for the purpose of seeking health care. The first usage primarily appears in the medical literature and is beyond the scope of this article, which focuses on travel to seek health care. Still, there are some aspects these two topics have in common: both are affected by ease and speed of international travel and communication associated with globalization, and both raise questions about continuity of care as well as issues related to cultural, language, and legal differences; both also raise questions about ethics. This article describes some of the motivating factors, contributing elements, and challenges in elucidating trends, as well as implications for clinicians who provide pretravel advice and those who care for ill returning travelers.

    In re-listening to the lectures of Charles Townes shortly after the invention of the laser (e.g., in the Boston Science Museum), one can already have a realistic vision of the potentialities of this new tool in the field of medical therapy, as evidenced by the use of the laser in ophthalmology to cure retinal detachment in the 1960's. Since then, applications have flourished in the domain of therapy. We will thus illustrate here only some of the main fields of application of medical lasers. On the opposite, the use of lasers in medical imaging is, with one exception in ophthalmology, still at the development level. It is becoming a diagnostic tool in addition to high performance imaging facilities that are often very expensive (such as CT scan, Magnetic Resonance Imaging (MRI) and nuclear imaging). Even if progress is sometimes slow, one can now image with light inside the human body, in spite of the strong scattering of light by tissues, in the same way as a pathologist sees surgical specimens.

    The technology and techniques for remote quantitative imaging of electrostatic potentials and electrostatic fields in and around objects and in free space is presented. Electric field imaging (EFI) technology may be applied to characterize intrinsic or existing electric potentials and electric fields, or an externally generated electrostatic field may be used for (illuminating) volumes to be inspected with EFI. The baseline sensor technology, electric field sensor (e-sensor), and its construction, optional electric field generation (quasistatic generator), and current e-sensor enhancements (ephemeral e-sensor) are discussed. Demonstrations for structural, electronic, human, and memory applications are shown. This new EFI capability is demonstrated to reveal characterization of electric charge distribution, creating a new field of study that embraces areas of interest including electrostatic discharge mitigation, crime scene forensics, design and materials selection for advanced sensors, dielectric morphology of structures, inspection of containers, inspection for hidden objects, tether integrity, organic molecular memory, and medical diagnostic and treatment efficacy applications such as cardiac polarization wave propagation and electromyography imaging.

    Electrical stimulation has a long history of use in medicine dating back to 46 A.D. when the Roman physician Largus found the electrical discharge of torpedo fishes useful in the treatment of pain produced by headache and gout. A rival Greek physician, Dioscorides, discounted the value of the torpedo fish for headache relief but did recommend its use in the treatment of hemorrhoids. In 1745, the Leyden jar and various sized electrostatic generators were used to treat angina pectoris, epilepsy, hemiplegia, kidney stones, and sciatica. Benjamin Franklin used an electrical device to treat successfully a young woman suffering from convulsive fits. In the late 1800's battery powered hydroelectric baths were used to treat chronic inflammation of the uterus while electrified athletic supporters were advertised for the treatment of male problems. Fortunately, such an amusing early history of the simple beginnings of electrical stimulation did not prevent eventual development of a variety of useful therapeutic and rehabilitative applications of electrical stimulation. Over the centuries electrical stimulation has survived as a modality in the treatment of various medical disorders with its primary application being in the rehabilitation area. Recently, a surge of new interest in electrical stimulation has been kindled by the work of a Russian sport scientist who reported remarkable muscle strength and endurance improvements in elite athletes. Yakov Kots reported his research on electric stimulation and strength improvements in 1977 at a Canadian-Soviet Exchange Symposium held at Concordia University in Montreal. Since then an explosion of new studies has been seen in both sport science and in medicine. Based upon the reported works of Kots and the present surge of new investigations, one could be misled as to the origin of electrical stimulation as a technique to increase muscle strength. As a matter of fact, electric stimulation has been used as a technique to improve

  1. Signal Cloaking by Electric Fish.

    PubMed

    Stoddard, Philip K; Markham, Michael R

    2008-01-01

    Electric fish produce weak electric fields to image their world in darkness and to communicate with potential mates and rivals. Eavesdropping by electroreceptive predators exerts selective pressure on electric fish to shift their signals into less-detectable high-frequency spectral ranges. Hypopomid electric fish evolved a signal-cloaking strategy that reduces their detectability by predators in the lab (and thus presumably their risk of predation in the field). These fish produce broad-frequency electric fields close to the body, but the heterogeneous local fields merge over space to cancel the low-frequency spectrum at a distance. Mature males dynamically regulate this cloaking mechanism to enhance or suppress low-frequency energy. The mechanism underlying electric-field cloaking involves electrogenic cells that produce two independent action potentials. In a unique twist, these cells orient sodium and potassium currents in the same direction, potentially boosting their capabilities for current generation. Exploration of such evolutionary inventions could aid the design of biogenerators to power implantable medical devices, an ambition that would benefit from the complete genome sequence of a gymnotiform fish.

    2016-01-01

    Important technological advances in the last decades paved the road to a great success story for electrically stimulating medical implants, including cochlear implants or implants for deep brain stimulation. However, there are still many challenges in reducing side effects and improving functionality and comfort for the patient. Two of the main challenges are the wish for smaller implants on one hand, and the demand for more stimulation channels on the other hand. But these two aims lead to a conflict of interests. This paper presents a novel design for an electrical feedthrough, the so called capacitive feedthrough, which allows both reducing the size, and increasing the number of included channels. Capacitive feedthroughs combine the functionality of a coupling capacitor and an electrical feedthrough within one and the same structure. The paper also discusses the progress and the challenges of the first produced demonstrators. The concept bears a high potential in improving current feedthrough technology, and could be applied on all kinds of electrical medical implants, even if its implementation might be challenging.

    The historical origins of medical physics are traced from the first use of weighing as a means of monitoring health by Sanctorius in the early seventeenth century to the emergence of radiology, phototherapy and electrotherapy at the end of the nineteenth century. The origins of biomechanics, due to Borelli, and of medical electricity following Musschenbroek's report of the Leyden Jar, are included. Medical physics emerged as a separate academic discipline in France at the time of the Revolution, with Jean Hallé as its first professor. Physiological physics flowered in Germany during the mid-nineteenth century, led by the work of Adolf Fick. The introduction of the term medical physics into English by Neil Arnott failed to accelerate its acceptance in Britain or the USA. Contributions from Newton, Euler, Bernoulli, Nollet, Matteucci, Pelletan, Gavarret, d'Arsonval, Finsen, Röntgen and others are noted. There are many origins of medical physics, stemming from the many intersections between physics and medicine. Overall, the early nineteenth-century definition of medical physics still holds today: 'Physics applied to the knowledge of the human body, to its preservation and to the cure of its illnesses'.

In the last three decades, in fact, ICT technology has strongly entered the health-care field, bringing in new techniques to support therapy and rehabilitation. In this frame, medical robotics is an expansion of the service and professional robotics as well as other technologies, as surgical navigation has been introduced especially in minimally invasive surgery. Localization systems also provide treatments in radiotherapy and radiosurgery with high precision. Virtual or augmented reality plays a role for both surgical training and planning and for safe rehabilitation in the first stage of the recovery from neurological diseases. Also, in the chronic phase of motor diseases, robotics helps with special assistive devices and prostheses. Although, in the past, the actual need and advantage of navigation, localization, and robotics in surgery and therapy has been in doubt, today, the availability of better hardware (e.g., microrobots) and more sophisticated algorithms(e.g., machine learning and other cognitive approaches)has largely increased the field of applications of these technologies,making it more likely that, in the near future, their presence will be dramatically increased, taking advantage of the generational change of the end users and the increasing request of quality in health-care delivery and management.

    Objectives To determine the past-year medical misuse prevalence for 4 controlled medication classes (pain, stimulant, sleeping, and antianxiety) among adolescents, and to assess substance use outcomes among adolescents who report medical misuse. Design A Web-based survey was self-administered by 2744 secondary school students in 2009-2010. Setting Two southeastern Michigan school districts. Participants The sample had a mean age of 14.8 years and was 51.1% female. The racial/ethnic distribution was 65.0% white, 29.5% African American, 3.7% Asian, 1.3% Hispanic, and 0.5% other. Main Outcome Measures Past-year medical use and misuse of 4 controlled medication classes. Results Eighteen percent of the sample reported past-year medical use of at least 1 prescribed controlled medication. Among past-year medical users, 22.0% reported misuse of their controlled medications, including taking too much, intentionally getting high, or using to increase alcohol or other drug effects. Medical misusers were more likely than nonmisusers to divert their controlled medications and to abuse other substances. The odds of a positive screening result for drug abuse were substantially higher among medical misusers (adjusted odds ratio, 7.8; 95% confidence interval, 4.3-14.2) compared with medical users who used their controlled medications appropriately. The odds of drug abuse did not differ between medical users who used their controlled medications appropriately and nonusers. Conclusions Most adolescents who used controlled medications took their medications appropriately. Substance use and diversion of controlled medications were more prevalent among adolescents who misused their controlled medications. Careful therapeutic monitoring could reduce medical misuse and diversion of controlled medications among adolescents. PMID:21810634

    The cannabis plant has been known to humanity for centuries as a remedy for pain, diarrhea and inflammation. Current research is inspecting the use of cannabis for many diseases, including multiple sclerosis, epilepsy, dystonia, and chronic pain. In inflammatory conditions cannabinoids improve pain in rheumatoid arthritis and:pain and diarrhea in Crohn's disease. Despite their therapeutic potential, cannabinoids are not free of side effects including psychosis, anxiety, paranoia, dependence and abuse. Controlled clinical studies investigating the therapeutic potential of cannabis are few and small, whereas pressure for expanding cannabis use is increasing. Currently, as long as cannabis is classified as an illicit drug and until further controlled studies are performed, the use of medical cannabis should be limited to patients who failed conventional better established treatment.

    Electrical impedance tomography extends to the new and new areas of the medical diagnostics: lungs, breast, prostate, etc. The feedback from the doctors who use our breast EIT diagnostic system has induced us to develop the 3D electrical impedance imaging device for diagnostics of the cervix of the uterus - gynecologic impedance tomograph (GIT). The device uses the same measuring approach as the breast imaging system: 2D flat array of the electrodes arranged on the probe with handle is placed against the body. Each of the 32 electrodes of the array is connected in turn to the current source while the rest electrodes acquire the potentials on the surface. The current flows through the electrode of the array and returns through the remote electrode placed on the patient's limb. The voltages are measured relative to another remote electrode. The 3D backprojection along equipotential surfaces is used to reconstruct conductivity distribution up to approximately 1 cm in depth. Small number of electrodes enables us to implement real time imaging with a few frames per sec. rate. The device is under initial testing and evaluation of the imaging capabilities and suitability of usage.

    Immunosuppressive agents are commonly used in the nephrologist's practice in the treatment of autoimmune and immune-mediated diseases and transplantation, and they are investigational in the treatment of AKI and ESRD. Drug development has been rapid over the past decades as mechanisms of the immune response have been better defined both by serendipity (the discovery of agents with immunosuppressive activity that led to greater understanding of the immune response) and through mechanistic study (the study of immune deficiencies and autoimmune diseases and the critical pathways or mutations that contribute to disease). Toxicities of early immunosuppressive agents, such as corticosteroids, azathioprine, and cyclophosphamide, stimulated intense investigation for agents with more specificity and less harmful effects. Because the mechanisms of the immune response were better delineated over the past 30 years, this specialty is now bestowed with a multitude of therapeutic options that have reduced rejection rates and improved graft survival in kidney transplantation, provided alternatives to cytotoxic therapy in immune-mediated diseases, and opened new opportunities for intervention in diseases both common (AKI) and rare (atypical hemolytic syndrome). Rather than summarizing clinical indications and clinical trials for all currently available immunosuppressive medications, the purpose of this review is to place these agents into mechanistic context together with a brief discussion of unique features of development and use that are of interest to the nephrologist.

    In the last three years the focus was on the information contained in the lightning measurement, which is independent of other meteorological measurements that can be made from space. The characteristics of lightning activity in mesoscale convective systems were quantified. A strong relationship was found between lightning activity and surface rainfall. It is shown that lightning provides a precursor signature for wet microbursts (the strong downdrafts that produce windshears hazardous to aircraft) and that the lightning signature is a direct consequence of storm evolution. The Universities Space Research Association (USRA) collaborated with NASA scientists in the preliminary analysis and scientific justification for the design and deployment of an optical instrument which can detect lightning from geostationary orbit. Science proposals for the NASA mesoscale science program and for the Tethered Satellite System were reviewed. The weather forecasting research and unmanned space vehicles. Software was written to ingest and analyze the lightning ground strike data on the MSFC McIDAS system. The capabilities which were developed have a wide application to a number of problems associated with the operational impacts of electrical discharge within the atmosphere.

    Flows in small size channels have been studied for a long time over multidisciplinary field such as chemistry, biology and medical through the various topics. Recently, the attempts of electricity generation from the small flows as a new area for energy harvesting in microfluidics have been reported. Here, we propose for the first time a new fluidic electricity generator (FEG) by modulating the electric double layer (EDL) with two phase flows of water and air without external power sources. We find that an electric current flowed by the forming/deforming of the EDL with a simple separated phase flow of water and air at the surface of the FEG. Electric signals between two electrodes of the FEG are checked from various water/air passing conditions. Moreover, we verify the possibility of a self-powered air slug sensor by applying the FEG in the detection of an air slug. PMID:26511626

    There is now a wide choice of medical imaging to show both focal and diffuse pathologies in various organs. Conventional radiology with plain films, fluoroscopy and contrast medium have many advantages, being readily available with low-cost apparatus and a familiarity that almost leads to contempt. The use of plain films in chest disease and in trauma does not need emphasizing, yet there are still too many occasions when the answer obtainable from a plain radiograph has not been available. The film may have been mislaid, or the examination was not requested, or the radiograph had been misinterpreted. The converse is also quite common. Examinations are performed that add nothing to patient management, such as skull films when CT will in any case be requested or views of the internal auditory meatus and heal pad thickness in acromegaly, to quote some examples. Other issues are more complicated. Should the patient who clinically has gall-bladder disease have more than a plain film that shows gall-stones? If the answer is yes, then why request a plain film if sonography will in any case be required to 'exclude' other pathologies especially of the liver or pancreas? But then should cholecystography, CT or scintigraphy be added for confirmation? Quite clearly there will be individual circumstances to indicate further imaging after sonography but in the vast majority of patients little or no extra information will be added. Statistics on accuracy and specificity will, in the case of gall-bladder pathology, vary widely if adenomyomatosis is considered by some to be a cause of symptoms or if sonographic examinations 'after fatty meals' are performed. The arguments for or against routine contrast urography rather than sonography are similar but the possibility of contrast reactions and the need to limit ionizing radiation must be borne in mind. These diagnostic strategies are also being influenced by their cost and availability; purely pragmatic considerations are not

    This study describes the occurrence of work-related injuries from thermal-, electrical- and chemical-burns among electric utility workers. We describe injury trends by occupation, body part injured, age, sex, and circumstances surrounding the injury. This analysis includes all thermal, electric, and chemical injuries included in the Electric Power Research Institute (EPRI) Occupational Health and Safety Database (OHSD). There were a total of 872 thermal burn and electric shock injuries representing 3.7% of all injuries, but accounting for nearly 13% of all medical claim costs, second only to the medical costs associated with sprain- and strain-related injuries (38% of all injuries). The majority of burns involved less than 1 day off of work. The head, hands, and other upper extremities were the body parts most frequently injured by burns or electric shocks. For this industry, electric-related burns accounted for the largest percentage of burn injuries, 399 injuries (45.8%), followed by thermal/heat burns, 345 injuries (39.6%), and chemical burns, 51 injuries (5.8%). These injuries also represented a disproportionate number of fatalities; of the 24 deaths recorded in the database, contact with electric current or with temperature extremes was the source of seven of the fatalities. High-risk occupations included welders, line workers, electricians, meter readers, mechanics, maintenance workers, and plant and equipment operators.

As scholars and consumers grapple with the meaning of innovation, one common critical theme to surface is that it constitutes undesirable medicalization. But we are embodied creatures who can often benefit from medical knowledge; in addition, rejection of medicalization may be in some cases based on an untenable appeal to nature. Harnessing the power of medicine for women's welfare requires us to rethink the goals of medicine as well as implement fundamental reforms.

    Ultrasound speckle is a granular texture pattern appearing in ultrasound imaging. It can be used to distinguish tissues and identify pathologies. Lorentz force electrical impedance tomography is an ultrasound-based medical imaging technique of the tissue electrical conductivity. It is based on the application of an ultrasound wave in a medium placed in a magnetic field and on the measurement of the induced electric current due to Lorentz force. Similarly to ultrasound imaging, we hypothesized that a speckle could be observed with Lorentz force electrical impedance tomography imaging. In this study, we first assessed the theoretical similarity between the measured signals in Lorentz force electrical impedance tomography and in ultrasound imaging modalities. We then compared experimentally the signal measured in both methods using an acoustic and electrical impedance interface. Finally, a bovine muscle sample was imaged using the two methods. Similar speckle patterns were observed. This indicates the existence of an 'acousto-electrical speckle' in the Lorentz force electrical impedance tomography with spatial characteristics driven by the acoustic parameters but due to electrical impedance inhomogeneities instead of acoustic ones as is the case of ultrasound imaging.

    Background There are several applications of electrical stimulation described in medical literature to accelerate wound healing and improve cutaneous perfusion. This is a simple technique that could be incorporated as an adjunctive therapy in plastic surgery. The objective of this review was to evaluate the results of randomized clinical trials that use electrical stimulation for wound healing. Method We identified 21 randomized clinical trials that used electrical stimulation for wound healing. We did not include five studies with treatment groups with less than eight subjects. Results Electrical stimulation was associated with faster wound area reduction or a higher proportion of wounds that healed in 14 out of 16 wound randomized clinical trials. The type of electrical stimulation, waveform, and duration of therapy vary in the literature. Conclusion Electrical stimulation has been shown to accelerate wound healing and increase cutaneous perfusion in human studies. Electrical stimulation is an adjunctive therapy that is underutilized in plastic surgery and could improve flap and graft survival, accelerate postoperative recovery, and decrease necrosis following foot reconstruction.

    Implantable defibrillators are lifesavers and have improved mortality rates in patients at risk of sudden death, both in primary and secondary prevention. However, they are unable to modify the myocardial substrate, which remains susceptible to life-threatening ventricular arrhythmias. Electrical storm is a clinical entity characterized the recurrence of hemodynamically unstable ventricular tachycardia and/or ventricular fibrillation, twice or more in 24 hours, requiring electrical cardioversion or defibrillation. With the arrival of the implantable cardioverter-defibrillator, this definition was broadened, and electrical storm is now defined as the occurrence of three or more distinct episodes of ventricular tachycardia or ventricular fibrillation in 24 hours, requiring the intervention of the defibrillator (anti-tachycardia pacing or shock). Clinical presentation can be very dramatic, with multiple defibrillator shocks and hemodynamic instability. Managing its acute presentation is a challenge, and mortality is high both in the acute phase and in the long term. In large clinical trials involving patients implanted with a defibrillator both for primary and secondary prevention, electrical storm appears to be a harbinger of cardiac death, with notably high mortality soon after the event. In most cases, the storm can be interrupted by medical therapy, though transcatheter radiofrequency ablation of ventricular arrhythmias may be an effective treatment for refractory cases. This narrative literature review outlines the main clinical characteristics of electrical storm and emphasises critical points in approaching and managing this peculiar clinical entity. Finally focus is given to studies that consider transcatheter ablation therapy in cases refractory to medical treatment. PMID:21468247

  15. Marijuana: modern medical chimaera.

    PubMed

    Lamarine, Roland J

    2012-01-01

    Marijuana has been used medically since antiquity. In recent years there has been a resurgence of interest in medical applications of various cannabis preparations. These drugs have been cited in the medical literature as potential secondary treatment agents for severe pain, muscle spasticity, anorexia, nausea, sleep disturbances, and numerous other uses. This article reviews the research literature related to medical applications of various forms of cannabis. Benefits related to medical use of cannabinoids are examined and a number of potential risks associated with cannabis use, both medical and recreational, are considered. There is a clearly identified need for further research to isolate significant benefits from the medical application of cannabinoids and to establish dosage levels, appropriate delivery mechanisms and formulations, and to determine what role, if any, cannabinoids might play in legitimate medical applications. It is also imperative to determine if reported dangers pose a significant health risks to users.

  16. Long-term sequelae of electrical injury

    PubMed Central

    Wesner, Marni L.; Hickie, John

    2013-01-01

    Abstract Objective To summarize the current evidence-based knowledge about the long-term sequelae of injuries from electrical current. Quality of evidence MEDLINE was searched for English-language articles published in the past 20 years using the following search terms: electrical, injuries, wound, trauma, accident, sequelae, long-term, follow-up, and aftereffects. For obvious reasons, it is unethical to randomly study electrical injury in controlled clinical trials. By necessity, this topic is addressed in less-rigorous observational and retrospective work and case studies. Therefore, the strength of the literature pertaining to the long-term sequelae of electrical injury is impaired by the necessity of retrospective methods and case studies that typically describe small cohorts. Main message There are 2 possible consequences of electrical injury: the person either survives or dies. For those who survive electrical injury, the immediate consequences are usually obvious and often require extensive medical intervention. The long-term sequelae of the electrical injury might be more subtle, pervasive, and less well defined, but can include neurologic, psychological, and physical symptoms. In the field of compensation medicine, determining causation and attributing outcome to an injury that might not result in objective clinical findings becomes a considerable challenge. Conclusion The appearance of these consequences of electrical injury might be substantially delayed, with onset 1 to 5 or more years after the electrical injury. This poses a problem for patients and health care workers, making it hard to ascribe symptoms to a remote injury when they might not arise until well after the incident event. PMID:24029506

    The progressive increase of medical negligence law suits requires an updated analysis of the current situation of medical liability in Chile. The application of a new criminal procedure will avoid criminal prosecution of doctors, transferring to the civil courts the pecuniary sanctions for malpractice. Medical negligence and damage inflicted by doctors that require compensation are explained. The most likely evolution of medical liability is proposed, through an increase in civil liability insurance and the necessary standardization of rules applicable to professional liability.

But it is justified all the same to ask whether the logical connection really caused the origin, the change, or the disappearance of the medical objects. The interaction of ideas and medical objects assure as much objectivity as possible. In consequence, the contents of the museums, medical objects, is an aspect rather that a branch of the history of medicine.

  16. Economics of electricity

    NASA Astrophysics Data System (ADS)

    Erdmann, G.

    2015-08-01

    The following text is an introduction into the economic theory of electricity supply and demand. The basic approach of economics has to reflect the physical peculiarities of electric power that is based on the directed movement of electrons from the minus pole to the plus pole of a voltage source. The regular grid supply of electricity is characterized by a largely constant frequency and voltage. Thus, from a physical point of view electricity is a homogeneous product. But from an economic point of view, electricity is not homogeneous. Wholesale electricity prices show significant fluctuations over time and between regions, because this product is not storable (in relevant quantities) and there may be bottlenecks in the transmission and distribution grids. The associated non-homogeneity is the starting point of the economic analysis of electricity markets.

    2008-07-01

    Electrical signaling, short-term memory and rapid closure of the carnivorous plant Dionaea muscipula Ellis (Venus flytrap) have been attracting the attention of researchers since the XIX century. We found that the electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf without mechanical stimulation of trigger hairs. The closing time of Venus flytrap by electrical stimulation is the same as mechanically induced closing. Transmission of a single electrical charge between a lobe and the midrib causes closure of the trap and induces an electrical signal propagating between both lobes and midrib. The Venus flytrap can accumulate small subthreshold charges, and when the threshold value is reached, the trap closes. Repeated application of smaller charges demonstrates the summation of stimuli. The cumulative character of electrical stimuli points to the existence of short-term electrical memory in the Venus flytrap.

    Historians are increasingly required to produce research that makes an impact. This is particularly the case for medical historians, partly because of our funders' expectations, but also because there is a sense that medical history can inform today's thorny debates about health. Unfortunately, many historians struggle to make an impact. I suggest that participating in medical conferences (broadly defined), not only provides opportunities to make an impact on the medical community, but also offers chances to observe and participate in medical history as it happens.

  1. The Nurse's Medication Day

    PubMed Central

    Jennings, Bonnie Mowinski; Sandelowski, Margarete; Mark, Barbara

    2014-01-01

    The medication administration stage of the medication-use process is especially vulnerable to error because errors are least likely to be caught before reaching the patient. Medication administration, however, remains poorly understood. In this article we describe medication administration as observed in an ethnographic study conducted on one medical and one surgical unit. A central finding was that medication administration entailed a complex mixture of varied and often competing demands that temporally structured the nurses' entire workday. Articulation work was evident in time management strategies nurses used to handle demands from institutional policies, technical devices, patients, the physical environment, and the medications themselves. The average number of doses of medication per patient was more than double the number policy groups have indicated. Medication administration is neither simply the giving of drugs nor does it have clearly defined temporal boundaries. Because of its inseparability from other nurses' work, medication administration inherently entails interruption, thereby calling into question the current emphasis on reducing interruptions as a tactic to decrease medication errors.

    Rapid, sequence-specific DNA detection is essential for applications in medical diagnostics and genetic screening. Electrical biosensors that use immobilized nucleic acids are especially promising in these applications because of their potential for miniaturization and automation. Current DNA detection methods based on sequencing by synthesis rely on optical readouts; however, a direct electrical detection method for this technique is not available. We report here an approach for direct electrical detection of enzymatically catalyzed DNA synthesis by induced surface charge perturbation. We discovered that incorporation of a complementary deoxynucleotide (dNTP) into a self-primed single-stranded DNA attached to the surface of a gold electrode evokes an electrode surface charge perturbation. This event can be detected as a transient current by a voltage-clamp amplifier. Based on current understanding of polarizable interfaces, we propose that the electrode detects proton removal from the 3′-hydroxyl group of the DNA molecule during phosphodiester bond formation.

    Yang, Lei; Zhang, Lijuan; Webster, Thomas J

    2011-09-01

    Carbon nanostructures (including carbon nanofibers, nanostructured diamond, fullerene materials and so forth) possess extraordinary physiochemical, mechanical and electrical properties attractive to bioengineers and medical researchers. In the past decade, numerous developments towards the fabrication and biological studies of carbon nanostructures have provided opportunities to improve orthopedic applications. Therefore, the aim of this article is to provide an up-to-date review on carbon nanostructure advances in orthopedic research. Orthopedic medical device applications of carbon nanotubes/carbon nanofibers and nanostructured diamond (including particulate nanodiamond and nanocrystalline diamond coatings) are emphasized here along with other carbon nanostructures that have promising potential. In addition, widely used fabrication techniques for producing carbon nanostructures in both the laboratory and in industry are briefly introduced. In conclusion, carbon nanostructures have demonstrated tremendous promise for orthopedic medical device applications to date, and although some safety, reliability and durability issues related to the manufacturing and implantation of carbon nanomaterials remain, their future is bright.

    An electrical connector is formed from a sheet of electrically conductive material that lies in between the two layers of nonconducting material that comprise the casing of an electrical chip. The connector is electrically connected to an electrical element embedded within the chip. An opening in the sheet is concentrically aligned with a pair of larger holes respectively bored through the nonconducting layers. The opening is also smaller than the diameter of an electrically conductive contact pin. However, the sheet is composed flexible material so that the opening adapts to the diameter of the pin when the pin is inserted therethrough. The periphery of the opening applies force to the sides of the pin when the pin is inserted, and thus holds the pin within the opening and in contact with the sheet, by friction. The pin can be withdrawn from the connector by applying sufficient axial force.

    A thermoacoustic magnetohydrodynamic electrical generator includes an intrinsically irreversible thermoacoustic heat engine coupled to a magnetohydrodynamic electrical generator. The heat engine includes an electrically conductive liquid metal as the working fluid and includes two heat exchange and thermoacoustic structure assemblies which drive the liquid in a push-pull arrangement to cause the liquid metal to oscillate at a resonant acoustic frequency on the order of 1,000 Hz. The engine is positioned in the field of a magnet and is oriented such that the liquid metal oscillates in a direction orthogonal to the field of the magnet, whereby an alternating electrical potential is generated in the liquid metal. Low-loss, low-inductance electrical conductors electrically connected to opposite sides of the liquid metal conduct an output signal to a transformer adapted to convert the low-voltage, high-current output signal to a more usable higher voltage, lower current signal.

    The electric field control of superparamagnetism is realized using a Cu/Ni system, in which the deposited Ni shows superparamagnetic behavior above the blocking temperature. An electric double-layer capacitor (EDLC) with the Cu/Ni electrode and a nonmagnetic counter electrode is fabricated to examine the electric field effect on magnetism in the magnetic electrode. By changing the voltage applied to the EDLC, the blocking temperature of the system is clearly modulated.

  16. Essays on electricity theft

    NASA Astrophysics Data System (ADS)

    Steadman, Keva Ullanda

    Electricity theft is a relatively unknown crime with high economic costs. In this dissertation, I try to identify the factors that motivate persons to steal electricity. First, I use a panel dataset of 97 countries spanning the five year period 2003--2007 to estimate a model that describes the effect of the unemployment rate, GDP per capita, male population and urbanization on theft, robbery and homicide rates. The results are consistent with previous empirical work on crime and economic opportunity. The second and main contribution of this paper is to estimate the same model using distribution loss as a proxy for electricity theft. The results show that the unemployment rate, a key explanatory economic factor for crime, cannot explain variation in electricity theft, although there is some evidence, albeit weak, supporting correlation in rich countries. Therefore, policies that target the reduction of property crime through a reduction in unemployment will have no effect on electricity theft. The third contribution relates to the role that political institutions play in the incentives to steal electricity. After control for socioeconomic factors, I find that there is no relationship between political governance indicators and electricity theft. In the second and third chapters, I compare the United States, a high income, low electricity theft country with Jamaica, a middle income, high electricity theft country. The effect of unemployment on electricity theft mirrors the results found in the first chapter. In the United States, electricity theft is affected by changes in economic conditions but in Jamaica, it is not. These results suggest that the state of institutions plays a role in how social norms are determined. Poor countries will be more likely than rich countries to have weak institutions with social norms that encourage electricity theft.

    Many people in developing countries cannot afford or rely on certain modes of electricity. We establish the reasonability of relying on lead-acid batteries, 9 V alkaline batteries, and lithium-ion batteries for charging low-voltage medical equipment. Based on the research and tests we conducted, we determined that using these battery types to charge medical devices truly is a reasonable solution.

    In this paper, we propose an extended car-following model and an electricity consumption model to study the effects of the road's slope on the electric vehicle's electricity consumption. The numerical results show that each electric vehicle's electricity consumption increases with the uphill's tilt angle and decreases with the downhill's tilt angle. In addition, each electric vehicle's electricity consumption increases with the uphill's (downhill's) length under a certain tilt angle.

    Electric pulp testing (EPT) has been available for more than a century and used in dental practices worldwide. This article provides an overview of this diagnostic aid. The PubMed database from 1953 was used initially; the reference list for pulp testing featured 1071 articles, and for EPT identified 121 papers. A forward search was undertaken on these articles and using selected author names. Potentially relevant material was also sought in contemporary endodontic texts, while older textbooks on endodontics, operative dentistry and pain revealed historic information and primary research not found electronically. A short account of the innervation of the pulp is followed by an historic overview. Clinical considerations discussed include tooth isolation, glove wearing and tester electrode placement. Orthodontic treatment, pacemaker wearing and patient medications are considered. Research applications are also discussed. While EPT is valuable, no single pulp testing technique can reliably diagnose all pulp conditions. Careful collection of patient history regarding the problem tooth and prudent use of appropriate radiographs are also helpful. The shortcomings of electric tests, especially in the case of immature and concussed teeth, must be understood. The demeanour of the patient and the responses given by control teeth also require careful consideration.

    In the past 100 years, there has been an explosion of medical knowledge-and in the next 50 years, more medical knowledge will be available than ever before. Regrettably, current medical practice has been unable to keep pace with this explosion of medical knowledge. Specialized medical knowledge has been confined largely to academic medical centers (i.e., teaching hospitals) and to specialists in major cities; it has been disconnected from primary care clinicians on the front lines of patient care. To bridge this disconnect, medical knowledge must be demonopolized, and a platform for collaborative practice amongst all clinicians needs to be created. A new model of health care and education delivery called Project ECHO (Extension for Community Healthcare Outcomes), developed by the first author, does just this. Using videoconferencing technology and case-based learning, ECHO's medical specialists provide training and mentoring to primary care clinicians working in rural and urban underserved areas so that the latter can deliver the best evidence-based care to patients with complex health conditions in their own communities. The ECHO model increases access to care in rural and underserved areas, and it demonopolizes specialized medical knowledge and expertise.

  15. Cannabinoids: Medical implications.

    2016-01-01

    Herbal cannabis has been used for thousands of years for medical purposes. With elucidation of the chemical structures of tetrahydrocannabinol (THC) and cannabidiol (CBD) and with discovery of the human endocannabinoid system, the medical usefulness of cannabinoids has been more intensively explored. While more randomized clinical trials are needed for some medical conditions, other medical disorders, like chronic cancer and neuropathic pain and certain symptoms of multiple sclerosis, have substantial evidence supporting cannabinoid efficacy. While herbal cannabis has not met rigorous FDA standards for medical approval, specific well-characterized cannabinoids have met those standards. Where medical cannabis is legal, patients typically see a physician who "certifies" that a benefit may result. Physicians must consider important patient selection criteria such as failure of standard medical treatment for a debilitating medical disorder. Medical cannabis patients must be informed about potential adverse effects, such as acute impairment of memory, coordination and judgment, and possible chronic effects, such as cannabis use disorder, cognitive impairment, and chronic bronchitis. In addition, social dysfunction may result at work/school, and there is increased possibility of motor vehicle accidents. Novel ways to manipulate the endocannbinoid system are being explored to maximize benefits of cannabinoid therapy and lessen possible harmful effects.

  17. Development of Implantable Medical Devices: From an Engineering Perspective

    PubMed Central

    2013-01-01

    From the first pacemaker implant in 1958, numerous engineering and medical activities for implantable medical device development have faced challenges in materials, battery power, functionality, electrical power consumption, size shrinkage, system delivery, and wireless communication. With explosive advances in scientific and engineering technology, many implantable medical devices such as the pacemaker, cochlear implant, and real-time blood pressure sensors have been developed and improved. This trend of progress in medical devices will continue because of the coming super-aged society, which will result in more consumers for the devices. The inner body is a special space filled with electrical, chemical, mechanical, and marine-salted reactions. Therefore, electrical connectivity and communication, corrosion, robustness, and hermeticity are key factors to be considered during the development stage. The main participants in the development stage are the user, the medical staff, and the engineer or technician. Thus, there are three different viewpoints in the development of implantable devices. In this review paper, considerations in the development of implantable medical devices will be presented from the viewpoint of an engineering mind. PMID:24143287

    DOEpatents

    Algrain, Marcelo C.

    2007-02-13

    Turbocompound systems can be used to affect engine operation using the energy in exhaust gas that is driving the available turbocharger. A first electrical device acts as a generator in response to turbocharger rotation. A second electrical device acts as a motor to put mechanical power into the engine, typically at the crankshaft. Apparatus, systems, steps, and methods are described to control the generator and motor operations to control the amount of power being recovered. This can control engine operation closer to desirable parameters for given engine-related operating conditions compared to actual. The electrical devices can also operate in "reverse," going between motor and generator functions. This permits the electrical device associated with the crankshaft to drive the electrical device associated with the turbocharger as a motor, overcoming deficient engine operating conditions such as associated with turbocharger lag.

  13. [Medical education and professionalism].

    PubMed

    Martins e Silva, João

    2013-01-01

    Is briefly analyzed the evolution that the objectives, strategies and models of medical education have had since their presentation and subsequent implementation of the famous model of Abraham Flexner, is now 103 years. Although globally accepted in their original pedagogical principles and instruments, that model does not have avoided the continuing dissatisfaction by the medical community and students and, most markedly in recent decades, the demanding of a most efficient health care by society, in general, and by patients in particular. In response to these ambitions, the medical community felt that it was essential to review the traditional criteria of medical professionalism, adapting them to a new paradigm of society and an appropriate and more efficient model of medical education. In this respect, are analyzed strategies and methodologies, apparently more suitable proposals for the inclusion of the principles and responsibilities of medical professionalism since the early period of pre-graduated medical education. It is assumed that the emphasis in teaching and practice of reflection throughout the course will have positive and lasting repercussions during active working life. However, the author believes that the success of the measures to be introduced in medical education programs to a new model of professionalism continues to depend, above all, of the humanistic and cognitive attributes of the students to be chosen, and the pedagogical quality, professional and academic of their teachers.

  11. Style in medical journals.

    PubMed Central

    Adams Smith, D E

    1983-01-01

    A study of medical journals from 1962 showed a constant preoccupation with style. Editors and contributors on both sides of the Atlantic revile unnecessary obscurity and complexity and the use of jargon, barbarisms, vogue words, and weak impersonal constructions. They bewail the pompous use of verbiage and the "medspeak" typified by acronyms and neologisms created by affixation. Suggestions for possible causes of poor medical style range from editorial demands for compression and a general ignorance of the principles of good writing to faulty logic and the subordination of communication to status seeking. The consequences of bad writing may include the fragmentation of knowledge, an increase in the importance of abstracting services, a trend towards free glossy medical newspapers, and, as remedial measures, workshops and courses in medical writing. Some implications for English language teachers working with foreign medical graduates and preclinical students are discussed. PMID:6414596

  12. A medical geographical anniversary.

    Barrett, F A

    1993-09-01

    It is now 200 years since L. L. Finke wrote his treatise on a global medical geography, Versuch einer allgemeinen medicinisch-praktischen Geographie. It was both the most extensive book in substantive content, and the most detailed in conceptual discussion on medical geography written to that point. Although it is one of the foundation pieces of medical geography, modern day practitioners seldom refer to Finke's work. There are two main reasons for this: with the exception of two passages, the work has never been translated from the original German, and many contemporary medical geographers believe that the field only developed in the mid-twentieth century. This paper's purpose is to demonstrate that this last point is unfounded and that recognition of Finke's seminal contribution is long over-due. On the 200th anniversary of the publication of An Attempt at a General Medical-Practical Geography Finke's great achievement is honoured.

    To support the medical research and the maintenance of crew health during the three Skylab missions, a medical operational support team was organized. The functions of this team ranged from medical data management to medical systems engineering monitoring during the flights. The capability to expand preflight and postflight medical research and analysis was supplied through the use of the Skylab mobile laboratories. These mobile laboratories were not only capable of being transported to the recovery ship for postflight use, but also served as a preflight test area for gathering crewman baseline data. The laboratories contained experiment hardware identical to that of the flight orbital workshop and a laboratory diagnostic facility that duplicated many of the capabilities of ground-based clinical laboratories.

  14. Effectiveness of pain management following electrical injury.

    2010-01-01

    The purpose of this study was to evaluate the effectiveness of pain management after electrical injury. A retrospective hospital chart review was conducted among electrically injured patients discharged from the outpatient burn clinic of a rehabilitation hospital (July 1, 1999, to July 31, 2008). Demographic data, numeric pain ratings (NPRs) at initial assessment and discharge, medications, nonpharmacologic modalities, and their effects before admission and after rehabilitation were collected. Pain management effects were compared between high (> or =1000 v) and low (<1000 v) voltage, and between electrical contact and electrical flash patients, using Student's t-test and chi, with a P < .05 considered significant. Of 82 electrical patients discharged during the study period, 27 were excluded because of incomplete data, leaving 55 patients who had a mean age +/-SD of 40.7 +/- 11.3 years, TBSA of 19.2 +/- 22.7%, and treatment duration of 16.5 +/- 15.7 months. The majority were men (90.9%), most injuries occurred at work (98.2%), mainly caused by low voltage (n = 32, 58.2%), and the rest caused by high voltage (n = 18, 32.7%). Electrical contact was more common (54.5%) than electrical flash (45.5%). Pain was a chief complaint (92.7%), and hands were the most affected (61.8%), followed by head and neck (38.2%), shoulders (38.2%), and back torso (38.2%). Before rehabilitation, the most common medication were opioids (61.8%), relieving pain in 82.4%, followed by acetaminophen (47.3%) alleviating pain in 84.6%. Heat treatment was the most common nonpharmacologic modality (20.0%) relieving pain in 81.8%, followed by massage therapy (14.5%) alleviating pain in 75.0%. During the rehabilitation program, antidepressants were the most common medication (74.5%), relieving pain in 22.0%, followed by nonsteroidal antiinflammatory drugs (61.8%), alleviating pain in 70.6%. Massage therapy was the most common nonpharmacologic modality (60.0%), alleviating pain in 75.8%, and then

    Electrical injury is a devastating and hard to treat clinical lesion. Fully understanding the pathophysiology of electrical trauma is still a challenge for clinicians and scientists. Further elucidating the natural history of this form of tissue injury could be helpful in improving limb salvage and offering stage-appropriate therapy. Multi-spectral imaging technique is a non-invasive technology that can be used to determine optical properties of tissues in and adjacent to injury. Images at different wavelengths can provide essential information related to the pathophysiological condition of the tissue. To promote the applicability of this technique in medical diagnosis, we built a complete experimental model of electrical injury. In this model, electrical injuries were created by a reliable high-tension shock system at preset voltage or current. A thermal camera recorded the change of skin temperature during the electrical shock. Then, a high-resolution spectral imaging system based on structured illumination was used to capture images for post analysis to extrapolate optical properties of the tissue. To test accuracy, this imaging system was calibrated by using a set of epoxy phantoms with known optical properties. In this paper, the results of experiments conducted on rats and discussions on the systemic changes in tissue optical properties before and after electrical shock are presented.

    A tertiary care 1000 bedded hospital contains more than 10,000 pieces of equipment worth approximately 41 million USD, while the power cords supplied along with the imported equipment do not comply with country-specific norms. Moreover, the local vendors procure power cords with type D/M plug to complete installation and also on-site electrical safety test is not performed. Hence, this project was undertaken to evaluate the electrical safety of all life-saving equipment purchased in the year 2013, referring to the guidelines of International Electrotechnical Commission 62353, the Association for the Advancement of Medical Instrumentation (AAMI) and National Fire Protection Association (NFPA)-99 hospital standard for the analysis of protective earth resistance and chassis leakage current.

  19. Electricity from biogas

    SciTech Connect

    Augenstein, D.; Benemann, J.; Hughes, E.

    1994-12-31

    Biogas is a medium-Btu methane and carbon dioxide mix produced by bacterial decomposition of organic matter. Its sources include landfills, waste water sludges, and animal wastes. It can fuel energy applications, of which electricity generation is a frequently-preferred option. The greatest current U.S. biogas recovery and energy use is at landfills, where biogas at about 80 landfill sites fuels a total of approximately 300 MWe. Wastewater treatment plants and confined animal waste management systems support additional electric power production. Generation of electricity from biogas can present difficulties due to the generally small scale of the generating facility, variable energy content of the gas, fluctuating availability, contaminant problems, and often-demanding control needs. However, such difficulties are being successfully addressed and economics for electricity generation are often favorable as biogas can be essentially {open_quotes}free{close_quotes} fuel. Biogas recovery and use has the additional advantage of mitigating a potent greenhouse gas. Biogas from U.S. landfills alone could fuel about 1% of U.S. electrical generation while giving climate change benefit equivalent to reducing CO{sub 2} emissions in the electricity sector by more than 10%. Growth in landfill gas use will be facilitated by recent regulations, advances in equipment, and improved management techniques such as {open_quotes}controlled landfilling{close_quotes}. The potential for biogas recovery and electricity production from sewage sludges, animal wastes and other organic resources such as agricultural residues is uncertain but probably exceeds the estimate for landfills.

    Futurist writing about technology emerged in the late 19th century at the same time as new kinds of electrical technology were making utopian futures seem practically attainable. Electrical writers and novelists alike thus borrowed from the popular "science" fiction of Jules Verne, Edward Bellamy and others to try to create self-fulfilling prophecies of a future in which electrical gadgets and machines met all major practical needs of civilization. To the extent that many parts of our world are populated by the hardware that they forecast, they succeeded in their goal.

  2. Coaxial Electric Heaters

    NASA Technical Reports Server (NTRS)

    Strekalov, Dmitry; Matsko, Andrey; Savchenkov, Anatoliy; Maleki, Lute

    2008-01-01

    Coaxial electric heaters have been conceived for use in highly sensitive instruments in which there are requirements for compact heaters but stray magnetic fields associated with heater electric currents would adversely affect operation. Such instruments include atomic clocks and magnetometers that utilize heated atomic-sample cells, wherein stray magnetic fields at picotesla levels could introduce systematic errors into instrument readings. A coaxial electric heater is essentially an axisymmetric coaxial cable, the outer conductor of which is deliberately made highly electrically resistive so that it can serve as a heating element. As in the cases of other axisymmetric coaxial cables, the equal magnitude electric currents flowing in opposite directions along the inner and outer conductors give rise to zero net magnetic field outside the outer conductor. Hence, a coaxial electric heater can be placed near an atomic-sample cell or other sensitive device. A coaxial electric heater can be fabricated from an insulated copper wire, the copper core of which serves as the inner conductor. For example, in one approach, the insulated wire is dipped in a colloidal graphite emulsion, then the emulsion-coated wire is dried to form a thin, uniform, highly electrically resistive film that serves as the outer conductor. Then the film is coated with a protective layer of high-temperature epoxy except at the end to be electrically connected to the power supply. Next, the insulation is stripped from the wire at that end. Finally, electrical leads from the heater power supply are attached to the exposed portions of the wire and the resistive film. The resistance of the graphite film can be tailored via its thickness. Alternatively, the film can be made from an electrically conductive paint, other than a colloidal graphite emulsion, chosen to impart the desired resistance. Yet another alternative is to tailor the resistance of a graphite film by exploiting the fact that its resistance

  4. BEEST: Electric Vehicle Batteries

    SciTech Connect

    2010-07-01

    BEEST Project: The U.S. spends nearly a $1 billion per day to import petroleum, but we need dramatically better batteries for electric and plug-in hybrid vehicles (EV/PHEV) to truly compete with gasoline-powered cars. The 10 projects in ARPA-E’s BEEST Project, short for “Batteries for Electrical Energy Storage in Transportation,” could make that happen by developing a variety of rechargeable battery technologies that would enable EV/PHEVs to meet or beat the price and performance of gasoline-powered cars, and enable mass production of electric vehicles that people will be excited to drive.

    This booklet explains the basic technology of nuclear fission power reactors, the nuclear fuel cycle and the role of nuclear energy as one of the domestic energy resources being developed to help meet our national energy demand. Nuclear power accounted for over 16 percent of the US electric energy supply in 1986 and was second only to coal as a source of our electric power. In the 1990s, nuclear energy is expected to provide almost 20 percent of the Nation's electricity. 38 figs., 5 tabs.

  6. Contactless Rotary Electrical Couplings

    NASA Technical Reports Server (NTRS)

    Kumagai, Hiroyuki

    2003-01-01

    Rotary electrical couplings based on induction (transformer action) rather than conduction between rotating and stationary circuitry have been invented. These couplings provide an alternative to slip rings and contact brushes. Mechanical imperfections of slip-ring and brush contact surfaces and/or dust particles trapped between these surfaces tend to cause momentary interruptions in electrical contact and thereby give rise to electrical noise. This source of noise can be eliminated in the inductive rotary couplings because no direct contact is necessary for transformer action.

    Exploration Medical Capability (ExMC) is an element of NASA's Human Research Program (HRP). ExMC's goal is to address the risk of the Inability to Adequately Recognize or Treat an Ill or Injured Crewmember. This poster highlights the approach ExMC has taken to address this goal and our current areas of interest. The Space Medicine Exploration Medical Condition List (SMEMCL) was created to identify medical conditions of concern during exploration missions. The list was derived from space flight medical incidents, the shuttle medical checklist, the International Space Station medical checklist, and expert opinion. The conditions on the list were prioritized according to mission type by a panel comprised of flight surgeons, physician astronauts, engineers, and scientists. From the prioritized list, the ExMC element determined the capabilities needed to address the medical conditions of concern. Where such capabilities were not currently available, a gap was identified. The element s research plan outlines these gaps and the tasks identified to achieve the desired capabilities for exploration missions. This poster is being presented to inform the audience of the gaps and tasks being investigated by ExMC and to encourage discussions of shared interests and possible future collaborations.

    Medication reviews have the potential to lower the incidence of prescribing errors. To benefit from a medication review, the prescriber must adhere to medication counselling. Adherence rates vary from 39 to 100%. The aim of this study was to examine counselling-naive hospital physicians' perspectives and demands to medication counselling as well as study factors that might increase adherence to the counselling. The study was conducted as a questionnaire survey among physicians at Aarhus University Hospital, Denmark. The questionnaire was developed based on focus group interviews and literature search, and was pilot-tested among 30 physicians before being sent to 669 physicians. The questionnaire consisted of 35 items divided into four categories: attitudes (19 items), behaviours (3 items), assessment (8 items) and demographics (5 items). The response rate was 60% (400/669). Respondents were employed at psychiatric, medical or surgical departments. Eighty-five per cent of respondents agreed that patients would benefit of an extra medication review, and 72% agreed that there was a need for external medication counselling. The most important factor that could increase adherence was the clinical relevance of the counselling as 78% rated it of major importance. The most favoured method for receiving counselling was via the electronic patient record.

    Advances in medical devices and health care has been phenomenal during the recent years. Although medical device manufacturers have been improving their instruments, network connection of these instruments still rely on proprietary technologies. Even if the interface has been provided by the manufacturer (e.g., RS-232, USB, or Ethernet coupled with a proprietary API), there is no widely-accepted uniform data model to access data of various bedside instruments. There is a need for a common standard which allows for internetworking with the medical devices from different manufacturers. ISO/IEEE 11073 (X73) is a standard attempting to unify the interfaces of all medical devices. X73 defines a client access mechanism that would be implemented into the communication controllers (residing between an instrument and the network) in order to access/network patient data. On the other hand, MediCAN technology suite has been demonstrated with various medical instruments to achieve interfacing and networking with a similar goal in its open standardization approach. However, it provides a more generic definition for medical data to achieve flexibility for networking and client access mechanisms. In this paper, a comparison between the data model of X73 and MediCAN will be presented to encourage interoperability demonstrations of medical instruments.

    In this presentation, as a member of the Harmonization by Doing (HBD) project, I discuss the significance of regulatory science in global medical device development and our experience in the international collaboration process for medical devices. In Japan, most innovative medical therapeutic devices were previously developed and exported by foreign-based companies. Due to this device lag, Japanese had minimal opportunities for receiving treatment with innovative medical devices. To address this issue, the Japanese government has actively accepted foreign clinical trial results and promoted global clinical trials in projects such as HBD. HBD is a project with stakeholders from academia, regulatory authorities, and industry in the US and Japan to promote global clinical trials and reduce device lags. When the project started, medical device clinical trials were not actively conducted in Japan at not just hospitals but also at medical device companies. We started to identify issues under the concept of HBD. After 10 years, we have now become key members in global clinical trials and able to obtain approvals without delay. Recently, HBD has started promoting international convergence. Physicians and regulatory authorities play central roles in compiling guidelines for the clinical evaluation of medical device development, which will be a more active field in the near future. The guidelines compiled will be confirmed with members of academia and regulatory authorities in the United Sates.

    The printing house of Benjamin Franklin produced several works of a medical nature in Colonial America at a time when very few medical treatises were being written or printed. Benjamin Franklin was also indirectly responsible for the founding of the first medical library in this country. For these reasons he was, in addition to his many other talents, an early contributor to American medical literature. Included in this bibliography are all the known medical books, pamphlets, and broadsides in English with Benjamin Franklin's name in the imprint, issued in America. These eighteen titles span the years 1732 to 1765 and are presented chronologically with indications of their relation to the practice and practitioners of Colonial medicine. Benjamin Franklin's press produced as wide a variety of contributions as did his versatile life, and the early history of medicine in this country bears the influence of both. I am pleased with your scheme of a Medical Library at the Hospital, and I fancy I can procure you some donations among my medical friends here, if you will send me a catalogue of what books you already have. Enclosed I send you the only book of the kind in my possession here, having just received it as a present from the author.—Benjamin Franklin to Dr. Cadwallader Evans, London, May 5, 1767 (1).

  14. Medical marijuana: Medical necessity versus political agenda

    Clark, Peter A.; Capuzzi, Kevin; Fick, Cameron

    2011-01-01

    Summary Marijuana is classified by the Drug Enforcement Agency (DEA) as an illegal Schedule I drug which has no accepted medical use. However, recent studies have shown that medical marijuana is effective in controlling chronic non-cancer pain, alleviating nausea and vomiting associated with chemotherapy, treating wasting syndrome associated with AIDS, and controlling muscle spasms due to multiple sclerosis. These studies state that the alleviating benefits of marijuana outweigh the negative effects of the drug, and recommend that marijuana be administered to patients who have failed to respond to other therapies. Despite supporting evidence, the DEA refuses to reclassify marijuana as a Schedule II drug, which would allow physicians to prescribe marijuana to suffering patients. The use of medical marijuana has continued to gain support among states, and is currently legal in 16 states and the District of Columbia. This is in stark contrast to the federal government’s stance of zero-tolerance, which has led to a heated legal debate in the United States. After reviewing relevant scientific data and grounding the issue in ethical principles like beneficence and nonmaleficence, there is a strong argument for allowing physicians to prescribe marijuana. Patients have a right to all beneficial treatments and to deny them this right violates their basic human rights. PMID:22129912

  15. Medical devices: US medical device regulation.

    PubMed

    Jarow, Jonathan P; Baxley, John H

    2015-03-01

    Medical devices are regulated by the US Food and Drug Administration (FDA) within the Center for Devices and Radiological Health. Center for Devices and Radiological Health is responsible for protecting and promoting the public health by ensuring the safety, effectiveness, and quality of medical devices, ensuring the safety of radiation-emitting products, fostering innovation, and providing the public with accurate, science-based information about the products we oversee, throughout the total product life cycle. The FDA was granted the authority to regulate the manufacturing and marketing of medical devices in 1976. It does not regulate the practice of medicine. Devices are classified based on complexity and level of risk, and "pre-1976" devices were allowed to remain on the market after being classified without FDA review. Post-1976 devices of lower complexity and risk that are substantially equivalent to a marketed "predicate" device may be cleared through the 510(k) premarket notification process. Clinical data are typically not needed for 510(k) clearance. In contrast, higher-risk devices typically require premarket approval. Premarket approval applications must contain data demonstrating reasonable assurance of safety and efficacy, and this information typically includes clinical data. For novel devices that are not high risk, the de novo process allows FDA to simultaneously review and classify new devices. Devices that are not legally marketed are permitted to be used for clinical investigation purposes in the United States under the Investigational Device Exemptions regulation.

  16. Medical education: creating physicians or medical technicians?

    PubMed

    Berkow, Robert

    2002-02-01

    The 20th century witnessed phenomenal growth in scientific medical knowledge and technology, enabling physicians to more accurately diagnose and effectively treat a wide range of diseases. However, these advances led to longer and more complex training periods for physicians and increasing specialization and dependence on the new technology. An adverse outcome of these changes has been the development of many physicians who are less able to communicate with their patients and deal with them in a humanistic and personally caring manner; ie, the development of finely trained medical technologists as opposed to caring physicians. Their behavior and their blind trust in science and technology without understanding the patients in whom illness occurs often leads to making incorrect, incomplete, or inappropriate diagnoses or to unnecessary failures of treatment. It also results in excessive costs, hazardous procedures, and ill will from patients. Unfortunately, such technologically oriented physicians are often the primary role models for students. The best hope for a remedy to the problem lies in recognizing that it exists, understanding its causes, and modifying medical education accordingly. Providing students with good role models and some rudimentary techniques can lead to significant gains, but sophisticated programs have been designed only in some schools.

    Many ocular medications are used by pediatricians or ophthalmologists caring for pediatric patients. Topical antibiotics are commonly prescribed for bacterial conjunctivitis, nasolacrimal duct obstructions, and ophthalmia neonatorum. Many new antiallergy eye drops are now available for the treatment of seasonal (hay fever) conjunctivitis. Dilating eye drops and antiglaucoma medications are generally used or prescribed by ophthalmologists, but pediatricians must be aware of their potentially serious systemic side effects. Before initiating treatment, physicians should evaluate the risks and benefits of ophthalmic medications, establish minimum dosages necessary to achieve a therapeutic benefit, and monitor children for local and systemic side effects.

    BACKGROUND: Exploration class missions will present significant new challenges and hazards to the health of the astronauts. Regardless of the intended destination, beyond low Earth orbit a greater degree of crew autonomy will be required to diagnose medical conditions, develop treatment plans, and implement procedures due to limited communications with ground-based personnel. SCOPE: The Exploration Medical System Demonstration (EMSD) project will act as a test bed on the International Space Station (ISS) to demonstrate to crew and ground personnel that an end-to-end medical system can assist clinician and non-clinician crew members in optimizing medical care delivery and data management during an exploration mission. Challenges facing exploration mission medical care include limited resources, inability to evacuate to Earth during many mission phases, and potential rendering of medical care by non-clinicians. This system demonstrates the integration of medical devices and informatics tools for managing evidence and decision making and can be designed to assist crewmembers in nominal, non-emergent situations and in emergent situations when they may be suffering from performance decrements due to environmental, physiological or other factors. PROJECT OBJECTIVES: The objectives of the EMSD project are to: a. Reduce or eliminate the time required of an on-orbit crew and ground personnel to access, transfer, and manipulate medical data. b. Demonstrate that the on-orbit crew has the ability to access medical data/information via an intuitive and crew-friendly solution to aid in the treatment of a medical condition. c. Develop a common data management framework that can be ubiquitously used to automate repetitive data collection, management, and communications tasks for all activities pertaining to crew health and life sciences. d. Ensure crew access to medical data during periods of restricted ground communication. e. Develop a common data management framework that

General considerations that apply to all patients include evaluation for coagulation disorders, prior anesthetic complications and drug history. Evaluation for organ-specific risk factors allows identification of patients at high surgical risk, minimization of risk and anticipation of postoperative complications. Review of the recent literature and a practical guide to therapy is presented for the major medical considerations before surgical procedures: cardiac disease, hypertension, pulmonary disease, endocrine considerations and hepatic disease. Attention to these areas and communication among internists, anesthesiologists and surgeons should provide optimal treatment of surgical patients with medical disease. PMID:7179956

Using boron etch stops and surface micromachining, microneedles with very smooth surfaces are made. Micromachining also allows for precision placement of electrodes by photolithography with micron sized gaps to allow for concentrated electric fields. A microcauterizer is fabricated by bulk etching silicon to form knife edges, then parallelly placed microelectrodes with gaps as small as 5 {mu}m are patterned and aligned adjacent the knife edges to provide homeostasis while cutting tissue. While most of the microelectrode lines are electrically insulated from the atmosphere by depositing and patterning silicon dioxide on the electric feedthrough portions, a window is opened in the silicon dioxide to expose the parallel microelectrode portion. This helps reduce power loss and assist in focusing the power locally for more efficient and safer procedures. 7 figs.

    Kern, Johannes; Kullock, René; Prangsma, Jord; Emmerling, Monika; Kamp, Martin; Hecht, Bert

    2015-09-01

    Unlike radiowave antennas, so far optical nanoantennas cannot be fed by electrical generators. Instead, they are driven by light or indirectly via excited discrete states in active materials in their vicinity. Here we demonstrate the direct electrical driving of an in-plane optical antenna by the broadband quantum-shot noise of electrons tunnelling across its feed gap. The spectrum of the emitted photons is determined by the antenna geometry and can be tuned via the applied voltage. Moreover, the direction and polarization of the light emission are controlled by the antenna resonance, which also improves the external quantum efficiency by up to two orders of magnitude. The one-material planar design offers facile integration of electrical and optical circuits and thus represents a new paradigm for interfacing electrons and photons at the nanometre scale, for example for on-chip wireless communication and highly configurable electrically driven subwavelength photon sources.

    NASA Astrophysics Data System (ADS)

    Frisk, Thomas; Roxhed, Niclas; Stemme, Göran

    2007-01-01

    This paper gives an in-depth description of two recent projects at the Royal Institute of Technology (KTH) which utilize MEMS and microsystem technology for realization of components intended for specific applications in medical technology and diagnostic instrumentation. By novel use of the DRIE fabrication technology we have developed side-opened out-of-plane silicon microneedles intended for use in transdermal drug delivery applications. The side opening reduces clogging probability during penetration into the skin and increases the up-take area of the liquid in the tissue. These microneedles offer about 200µm deep and pain-free skin penetration. We have been able to combine the microneedle chip with an electrically and heat controlled liquid actuator device where expandable microspheres are used to push doses of drug liquids into the skin. The entire unit is made of low cost materials in the form of a square one cm-sized patch. Finally, the design, fabrication and evaluation of an integrated miniaturized Quartz Crystal Microbalance (QCM) based "electronic nose" microsystem for detection of narcotics is described. The work integrates a novel environment-to-chip sample interface with the sensor element. The choice of multifunctional materials and the geometric features of a four-component microsystem allow a functional integration of a QCM crystal, electrical contacts, fluidic contacts and a sample interface in a single system with minimal assembly effort, a potential for low-cost manufacturing, and a few orders of magnitude reduced in system size (12*12*4 mm 3) and weight compared to commercially available instruments. The sensor chip was successfully used it for the detection of 200 ng of narcotics sample.

  20. Medical problems in pregnancy.

    PubMed

    Narayan, Bhaskar; Nelson-Piercy, Catherine

    2016-12-01

    The prevalence of medical problems in pregnancy is increasing because of a complex interplay between demographic and lifestyle factors, and developments in modern medicine. Maternal mortality and morbidity resulting from treatable medical conditions, such as venous thromboembolism, epilepsy and autoimmune disease, have not decreased in recent years. This is despite a marked decrease in overall maternal mortality. It is vital that all physicians acquire a basic knowledge and understanding of medical problems in pregnancy. This includes prepregnancy measures such as counselling and optimisation of medical therapy, as well as multidisciplinary management throughout pregnancy and the postpartum period. Prompt recognition and treatment of acute and chronic illness is of clear benefit, and most drugs and many radiological investigations may be used in pregnancy.

  7. The earliest medical texts.

    PubMed

    Frey, E F

    The first civilization known to have had an extensive study of medicine and to leave written records of its practices and procedures was that of ancient Egypt. The oldest extant Egyptian medical texts are six papyri from the period between 2000 B.C. and 1500 B.C.: the Kahun Medical Papyrus, the Ramesseum IV and Ramesseum V Papyri, the Edwin Smith Surgical Papyrus, The Ebers Medical Papyrus and the Hearst Medical Papyrus. These texts, most of them based on older texts dating possibly from 3000 B.C., are comparatively free of the magician's approach to treating illness. Egyptian medicine influenced the medicine of neighboring cultures, including the culture of ancient Greece. From Greece, its influence spread onward, thereby affecting Western civilization significantly.

  16. Medical futility and nursing.

    PubMed

    1995-01-01

    Defining medical futility is central to the efforts of clinicians and ethicists who seek to identify the limits of patient autonomy. This article is a critique of current efforts to define and then use policies of medical futility to justify refusing requests for treatment and care that have no perceived medical benefit. After exploring the current definitions of medical futility in the bioethics and clinical literature, comparisons of the advantages and disadvantages of the following three options are provided: allowing patients to decide all but physiologic futility, allowing clinicians to decide futility, and pursuing negotiated compromise. The third option--negotiated compromise--is recommended. A role is developed for nurses in preventing and resolving conflict about futile treatment.

  17. Secure medical digital libraries.

    PubMed

    Papadakis, I; Chrissikopoulos, V; Polemi, D

    2001-12-01

    In this paper, a secure medical digital library is presented. It is based on the CORBA specifications for distributed systems. The described approach relies on a three-tier architecture. Interaction between the medical digital library and its users is achieved through a Web server. The choice of employing Web technology for the dissemination of medical data has many advantages compared to older approaches, but also poses extra requirements that need to be fulfilled. Thus, special attention is paid to the distinguished nature of such medical data, whose integrity and confidentiality should be preserved at all costs. This is achieved through the employment of Trusted Third Parties (TTP) technology for the support of the required security services. Additionally, the proposed digital library employs smartcards for the management of the various security tokens that are used from the above services.

  18. Medical Ghost-Writing

    PubMed Central

    Langdon-Neuner, Elise

    2008-01-01

    Any assistance an author receives with writing a scientific article that is not acknowledged in the article is described as ghost-writing. Articles ghost-written by medical writers engaged by pharmaceutical companies who have a vested interest in the content have caused concern after scandals revealed misleading content in some articles. A key criterion of authorship in medical journals is final approval of the article submitted for publication. Authors are responsible for the content of their articles and for acknowledging any assistance they receive. Action taken by some journals and medical writer associations to encourage acknowledgement is an uphill task in the light of disinterest from the pharmaceutical industry and ignorance or similar lack of interest by those who agree to be named authors. However, acknowledgment alone is not sufficient to resolve medical ghost-writing; issues of how the acknowledgement is formulated, permission to acknowledge and access to raw data also need to be tackled.

    PubMed

    Conrardy, Julie; Hillanbrand, Mary; Myers, Sandra; Nussbaum, George F

    2010-06-01

    Medical waste is a necessary by-product of any hospital environment; however, the majority of regulated medical waste is produced in the OR from the use of disposable surgical supplies (eg, drapes, gowns, basins, gloves, sponges). We conducted a concept comparison project in the ORs of two large medical centers in Bethesda, Maryland, and Washington, DC, to evaluate the effects of using reusable surgical basins, gowns, and table and Mayo stand covers in place of disposable products. Survey results indicated that surgeons and surgical technologists found the reusable products to be preferable to the disposable products currently in use. In addition, using reusable products provided a means to decrease regulated medical waste generated in the OR by an average of 65% as well as reduce the cost of waste disposal. AORN recommends evaluating the environmental effects of using reusable, reposable, and disposable products; our findings provide evidence that may be useful to surgical facilities that seek to adopt a "green" approach.

    Data generated in all clinical trial are recorded on the data collection instrument Case report Form / Electronic Case Report Form by investigators located at various sites in various countries. In multicentric clinical trials since different investigator or medically qualified experts are from different sites / centers recording the medical term(s) uniformly is a big challenge. Medical coders from clinical data management team process these terms and perform medical coding. Medical coding is performed to categorize the medical terms reported appropriately so that they can be analyzed/reviewed. This article describes process which is used for medical coding in clinical data management and two most commonly used medical dictionaries MedDRA and WHO-DDE in brief. It is expected to help medical coders to understand the process of medical coding in clinical data management. Few common issues which the medical coder faces while performing medical coding, are also highlighted.

    NASA Astrophysics Data System (ADS)

    Niraula, D.; McCulloch, J.; Warrell, G. R.; Irving, R.; Karpov, V. G.; Shvydka, Diana

    2016-07-01

    We have investigated the impact of strong (˜104 V/cm) electric fields on the development of Zn whiskers. The original samples, with considerable whisker infestation were cut from Zn-coated steel floors and then exposed to electric fields stresses for 10-20 hours at room temperature. We used various electric field sources, from charges accumulated in samples irradiated by: (1) the electron beam of a scanning electron microscope (SEM), (2) the electron beam of a medical linear accelerator, and (3) the ion beam of a linear accelerator; we also used (4) the electric field produced by a Van der Graaf generator. In all cases, the exposed samples exhibited a considerable (tens of percent) increase in whiskers concentration compared to the control sample. The acceleration factor defined as the ratio of the measured whisker growth rate over that in zero field, was estimated to approach several hundred. The statistics of lengths of e-beam induced whiskers was found to follow the log-normal distribution known previously for metal whiskers. The observed accelerated whisker growth is attributed to electrostatic effects. These results offer promise for establishing whisker-related accelerated life testing protocols.

Of late, community is getting increasingly aware of its health rights, gradually community participation in health matters including quantum and quality of case, has started increasing. Thus community leaders have started demanding for quality of medical care and accountability of those, responsible for delivery of medical care at various levels. 3. Medical audit or Evaluation of medical care is an answer to ensure the quality of care. But there are misgivings and distrust about medical audit due to its terminology. 4. There is need to education the medical, nursing and paramedical staff regarding medical audit and its sole purpose of self education and improvement of patient care activity. The present paper spells out fundamentals of medical audit, its scope and limitations.

The vehicle will be a heavy class urban transit bus offering double the fuel economy of today's buses and emissions that are reduced to 1/10th of the Environmental Protection Agency's standards. At the heart of the vehicle's drive train is a natural-gas-fueled engine. Initially, a small automotive engine will be tested as a baseline. This will be followed by the introduction of an advanced gas turbine developed from an aircraft jet engine. The engine turns a high-speed generator, producing electricity. Power from both the generator and an onboard energy storage system is then provided to a variable-speed electric motor attached to the rear drive axle. An intelligent power-control system determines the most efficient operation of the engine and energy storage system.

  2. Cryogenic Electric Motor Tested

    Brown, Gerald V.

    Technology for pollution-free "electric flight" is being evaluated in a number of NASA Glenn Research Center programs. One approach is to drive propulsive fans or propellers with electric motors powered by fuel cells running on hydrogen. For large transport aircraft, conventional electric motors are far too heavy to be feasible. However, since hydrogen fuel would almost surely be carried as liquid, a propulsive electric motor could be cooled to near liquid hydrogen temperature (-423 F) by using the fuel for cooling before it goes to the fuel cells. Motor windings could be either superconducting or high purity normal copper or aluminum. The electrical resistance of pure metals can drop to 1/100th or less of their room-temperature resistance at liquid hydrogen temperature. In either case, super or normal, much higher current density is possible in motor windings. This leads to more compact motors that are projected to produce 20 hp/lb or more in large sizes, in comparison to on the order of 2 hp/lb for large conventional motors. High power density is the major goal. To support cryogenic motor development, we have designed and built in-house a small motor (7-in. outside diameter) for operation in liquid nitrogen.

    Halapy, Henry; Kertland, Heather

    2012-01-01

    Background: Accurate and complete medication histories are not always obtained in clinical practice. Objective: This qualitative research study was undertaken to explore the barriers to and facilitators of obtaining accurate medication histories. Methods: Individual interviews, based on a structured interview guide, were conducted with 25 patients from both inpatient and ambulatory care clinic settings. Focus groups, based on a semistructured interview guide, were conducted with pharmacists, medical residents, and nurses. Transcribed data were analyzed by forming coded units and assessing these units for emerging themes. Results: Major themes that emerged from the patient interviews included patient ownership of health and medication knowledge (with knowledge of medications and their side effects and how to take medications being seen as important), patient-specific strategies to improve medication histories (e.g., use of regularly updated medication lists), and suggestions for system-level facilitators to improve medication histories (e.g., centralized databases of medication histories, increased patient education regarding the use and purpose of medications). Major themes also emerged from focus groups with health care professionals, including shared responsibility for medication history-taking among all 3 health care professions, perceptions about the barriers to medication history-taking (including patients not knowing their medications and not bringing their medication lists), and suggestions to improve medication histories (e.g., educating patients to bring medication vials to hospital admissions and appointments, using a centralized computer database for medication histories). Conclusions: Key recommendations resulting from this study include using standardized documentation techniques for medication histories, recording of medication history information in centralized electronic databases, educating patients to bring medications to every health care visit

    2001-01-01

    With the growing use of Natural Language Processing (NLP) techniques as solutions in Medical Informatics, the need to quickly and efficiently create the knowledge structures used by these systems has grown concurrently. Automatic discovery of a lexicon for use by an NLP system through machine learning will require information about the syntax of medical language. Understanding the syntactic differences between medical and non-medical corpora may allow more efficient acquisition of a lexicon. Three experiments designed to quantify the syntactic differences in medical and non-medical corpora were conducted. The results show that the syntax of medical language shows less variation than non-medical language and is likely simpler. The differences were great enough to question the applicability of general language tools on medical language. These differences may reduce the difficulty of some free text machine learning problems by capitalizing on the simpler nature of narrative medical syntax.

    Objectives: This study aimed to understand why people seek medical advice abroad given the trouble and expense this entails. The types of medical problems for which treatment abroad was sought, preferred destinations and satisfaction with the treatment were explored. A secondary aim was to give feedback to stakeholders in the health care system on how to handle this issue and meet the needs of the community. Methods: 45 patients who had recently travelled abroad for treatment were asked to complete a questionnaire or were interviewed by telephone. Results: 40 questionnaires were received. 68% of the respondents were male. Orthopaedic diseases were the most common conditions leading patients to seek treatment abroad. Thailand was the most popular destination followed by India (50% and 30% respectively). 85% of respondents went abroad for treatment only, 10% for treatment and tourism and 2.5% were healthy, but travelled abroad for a checkup. Interestingly, 15% of the participants went abroad without first seeking medical care locally. Out of those initially treated in Oman, 38.2% had no specific diagnosis and 38.2% had received treatment, but it was not effective. 73% of respondents obtained information on treatment abroad from a friend. The Internet and medical tourism offices were the least used sources of information. 15% of the patients experienced complications after their treatment abroad. Conclusion: Various facts about medical treatment abroad need to be disseminated to the public. This will necessitate greater effort in public health promotion and education. PMID:22087396

  9. Gender and medical careers.

    PubMed

    Riska, Elianne

    2011-03-01

    The concerns about physicians' career advancement tend to be raised in gender terms, because women presently constitute close to and will soon form a majority of the medical students in most western societies. The question is to what extent female and male medical students and residents today make similar or different career and lifestyle choices? Two major mechanisms have been referred to as the reason for gender differences in career paths for physicians. The major theoretical framework tends to be the socialization or sex-role theory and later versions of this explanatory framework. The other mechanism referred to is structural and points to the barriers or the concrete support that women and men experience in making their career decisions. Studies of medical students in the UK and US have shown that women students expected family demands to hamper career plans, while male students were less influenced by family concerns. The importance of role models and mentors in setting the career goals of medical students and residents has recently confirmed early studies of the topic. A number of studies have documented that early negative experiences or lack of encouragement in medical school deter women from choosing surgery as a career. Recent studies suggest that lifestyle choices rather than merely career advancement influence both female and male surgeons' career plans.

    Undergraduate medical education in Sweden has moved from nationally regulated, subject-based courses to programmes integrated either around organ systems or physiological and patho-physiological processes, or organised around basic medical science in conjunction with clinical specialities, with individual profiles at the seven medical schools. The national regulations are restricted to overall academic and professional outcomes. The 5½ year long university undergraduate curriculum is followed by a mandatory 18 months internship, delivered by the County Councils. While quality control and accreditation for the university curriculum is provided by the Swedish National Agency for Higher Education, no such formal control exists for the internship; undergraduate medical education is therefore in conflict with EU directives from 2005. The Government is expected to move towards 6 years long university undergraduate programmes, leading to licence, which will facilitate international mobility of both Swedish and foreign medical students and doctors. Ongoing academic development of undergraduate education is strengthened by the Bologna process. It includes outcome (competence)-based curricula, university Masters level complying with international standards, progression of competence throughout the curriculum, student directed learning, active participation and roles in practical clinical education and a national assessment model to assure professional competence. In the near future, the dimensioning of Swedish undergraduate education is likely to be decided more by international demands and aspects of quality than by national demands for doctors.

  11. Cynicism among medical students.

    PubMed

    Kopelman, L

    1983-10-21

    The thesis that medical students become more cynical than students of other professions seems justified in light of psychological studies and reports from medical students. This article explores whether this might be due, in part, to disappointment about how important ideals are followed. Psychological tests themselves offer an opportunity to examine this, because the medical profession espouses the goals of gaining proper consent from all subjects, including students, and of giving appropriate attention to excellence of research design and method. When studies used to evaluate medical students' attitudes are viewed from this perspective, however, weaknesses on both scores seem apparent. Students seem well aware of some of these flaws. Although such testing is a small part of medical education, it confirms students' views that there is cause for disillusionment about how certain goals are realized. It also suggests a way to cure some students' cynicism. Students should be taught consistently, both by example as well as by precept of their profession's sincere commitment to professed goals. In practical terms this means, for example, that studies using students as subjects should have a proper review by the institutional review board, with adequate attention given to excellence of design, confidentiality, and methods of gaining informed and unpressured consent. Such studies could then serve as paradigms to students. Other goals of the profession should also be applied to students, and applied for students.

  12. Financing medical education.

    PubMed

    Petersdorf, R G

    1991-02-01

    The cost of a medical education may dissuade qualified young people from entering the medical profession or may so load them with debt that they cannot pursue relatively low-paid careers in primary care or clinical investigation. Three aspects of this problem are examined: (1) the cost of medical school, (2) the magnitude of student indebtedness, and (3) the effects of this indebtedness on career choices. High tuition and fees require many students to assume sizable educational debts, some of which are so large that the trainees will be unable to repay them unless they enter highly remunerative specialties. Also, high levels of indebtedness may increase default levels once graduates feel the full impact of scheduled repayments. Several steps would help to alleviate this problem, but are unlikely to solve it. First, medical schools should lower tuition or at least declare a moratorium on increases. Second, limits should be imposed on the amount of total education debt a student is allowed to assume. Third, hospitals with extensive residency programs should assume some responsibility for helping trainees manage their finances. Fourth, the government should institute a loan forgiveness program that addresses the need for physician-investigators, primary care physicians, those willing to practice in underserved areas, and those from underrepresented minorities. And fifth, all institutions involved in medical training and its finance should work together to advise students on managing their debts.

    The Japanese Medical Education system has been influenced by political events throughout the country's history. From long periods of isolation from the western world to the effect of world wars, Japan's training system for physicians has had to adapt in many ways and will continue to change. The Japanese medical education system was recently compared to the “Galapagos Islands” for its unusual and singular evolution, in a speech by visiting professor Dr. Gordon L. Noel at the University of Tokyo International Research center.1 Japanese medical schools are currently working to increase their students' clinical hours or else these students may not be able to train in the United States for residencies. Knowing the history of the Japanese Medical education system is paramount to understanding the current system in place today. Studying the historical foundation of this system will also provide insight on how the system must change in order to produce better clinicians. This article provides a glimpse into the medical system of another nation that may encourage needed reflection on the state of current healthcare training in the United States. PMID:25821652

    A Draft Technical Information Document (HNF-1855) is being prepared to evaluate proposed interim tritium and medical isotope production at the Fast Flux Test Facility (FFTF). This assessment examines the potential health and safety impacts of transportation operations associated with the production of medical isotopes. Incident-free and accidental impacts are assessed using bounding source terms for the shipment of nonradiological target materials to the Hanford Site, the shipment of irradiated targets from the FFTF to the 325 Building, and the shipment of medical isotope products from the 325 Building to medical distributors. The health and safety consequences to workers and the public from the incident-free transportation of targets and isotope products would be within acceptable levels. For transportation accidents, risks to works and the public also would be within acceptable levels. This assessment is based on best information available at this time. As the medical isotope program matures, this analysis will be revised, if necessary, to support development of a final revision to the Technical Information Document.

    Background: The BC Medication Management Project (BCMMP) was developed by the BC Ministry of Health and the BC Pharmacy Association. This pilot project ran from September 2010 to January 2012. Pharmacists reviewed patients’ medication histories, discussed best use of medications, provided education and monitored for adverse effects, developed a plan to deal with medication issues and created a best possible medication history. Methods: To evaluate the experience of participating in the BCMMP, challenges and strengths of the project and the alignment of these experiences with the overarching goals, focus groups and interviews were conducted with 6 stakeholder groups. Themes were compared within and across stakeholder type and descriptively analyzed. Results: A total of 88 people participated in the focus groups/interviews. Pharmacists stated that providing BCMMP services was professionally satisfying and concurred with patients that the service did benefit them. However, participating in the BCMMP was not seen as financially sustainable by pharmacy owners, and there were concerns about patient selection. Physicians expressed concerns about increased workload associated with the BCMMP, for which they were not compensated. The computer system and burden of documentation were identified as the greatest problems. Conclusions: The BCMMP pilot project was enthusiastically received by pharmacists and patients who felt that it benefited patients and moved the pharmacy profession in a positive direction. It was widely felt that the BCMMP could be successful and sustainable if the identified challenges are addressed. PMID:25983759

    2014-07-01

    In this paper, electrical analogous models of fractional hereditary materials are introduced. Based on recent works by the authors, mechanical models of materials viscoelasticity behavior are firstly approached by using fractional mathematical operators. Viscoelastic models have elastic and viscous components which are obtained by combining springs and dashpots. Various arrangements of these elements can be used, and all of these viscoelastic models can be equivalently modeled as electrical circuits, where the spring and dashpot are analogous to the capacitance and resistance, respectively. The proposed models are validated by using modal analysis. Moreover, a comparison with numerical experiments based on finite difference time domain method shows that, for long time simulations, the correct time behavior can be obtained only with modal analysis. The use of electrical analogous in viscoelasticity can better reveal the real behavior of fractional hereditary materials.

The energy requirements of candidate high-energy missions gaining in NASA priority are used to highlight the potential of electric propulsion. Mission-propulsion interfaces are examined to point out differences between chemical and electric applications. Brief comparisons between ballistic requirements and capabilities and those of electric propulsion show that electric propulsion is presently the most practical and perhaps the only technology which can accomplish missions with these energy requirements.

  5. Electrical Conductivity in Textiles

    NASA Technical Reports Server (NTRS)

    2006-01-01

    Copper is the most widely used electrical conductor. Like most metals, though, it has several drawbacks: it is heavy, expensive, and can break. Fibers that conduct electricity could be the solutions to these problems, and they are of great interest to NASA. Conductive fibers provide lightweight alternatives to heavy copper wiring in a variety of settings, including aerospace, where weight is always a chief concern. This is an area where NASA is always seeking improved materials. The fibers are also more cost-effective than metals. Expenditure is another area where NASA is always looking to make improvements. In the case of electronics that are confined to small spaces and subject to severe stress, copper is prone to breaking and losing connection over time. Flexible conductive fibers eliminate that problem. They are more supple and stronger than brittle copper and, thus, find good use in these and similar situations. While clearly a much-needed material, electrically conductive fibers are not readily available. The cost of new technology development, with all the pitfalls of troubleshooting production and the years of testing, and without the guarantee of an immediate market, is often too much of a financial hazard for companies to risk. NASA, however, saw the need for electrical fibers in its many projects and sought out a high-tech textile company that was already experimenting in this field, Syscom Technology, Inc., of Columbus, Ohio. Syscom was founded in 1993 to provide computer software engineering services and basic materials research in the areas of high-performance polymer fibers and films. In 1999, Syscom decided to focus its business and technical efforts on development of high-strength, high-performance, and electrically conductive polymer fibers. The company developed AmberStrand, an electrically conductive, low-weight, strong-yet-flexible hybrid metal-polymer YARN.

  6. Electrical percolation based biosensors.

    Bruck, Hugh Alan; Yang, Minghui; Kostov, Yordan; Rasooly, Avraham

    2013-10-01

    A new approach to label free biosensing has been developed based on the principle of "electrical percolation". In electrical percolation, long-range electrical connectivity is formed in randomly oriented and distributed systems of discrete elements. By applying this principle to biological interactions, it is possible to measure biological components both directly and electronically. The main element for electrical percolation biosensor is the biological semiconductor (BSC) which is a multi-layer 3-D carbon nanotube-antibody network. In the BSC, molecular interactions, such as binding of antigens to the antibodies, disrupt the network continuity causing increased resistance of the network. BSCs can be fabricated by immobilizing conducting elements, such as pre-functionalized single-walled carbon nanotubes (SWNTs)-antibody complex, directly onto a substrate, such as a Poly(methyl methacrylate) (PMMA) surface (also known as plexi-glass or Acrylic). BSCs have been demonstrated for direct (label-free) electronic measurements of antibody-antigen binding using SWNTs. If the concentration of the SWNT network is slightly above the electrical percolation threshold, then binding of a specific antigen to the pre-functionalized SWNT dramatically increases the electrical resistance due to changes in the tunneling between the SWNTs. Using anti-staphylococcal enterotoxin B (SEB) IgG as a "gate" and SEB as an "actuator", it was demonstrated that the BSC was able to detect SEB at concentrations of 1 ng/ml. Based on this concept, an automated configuration for BSCs is described here that enables real time continuous detection. The new BSC configuration may permit assembly of multiple sensors on the same chip to create "biological central processing units (CPUs)" with multiple biological elements, capable of processing and sorting out information on multiple analytes simultaneously.

    Motivation is a concept which has fascinated researchers for many decades. The field of medical education has become interested in motivation recently, having always assumed that medical students must be motivated because of their commitment to highly specific training, leading to a very specific profession. However, motivation is a major determinant of the quality of learning and success, the lack of which may well explain why teachers sometimes observe medical students who are discouraged, have lost interest or abandon their studies, with a feeling of powerlessness or resignation. After describing the importance of motivation for learning in medicine, this Guide will define the concept of motivation, setting it within the context of a social cognitive approach. In the second part of this Guide, recommendations are made, based upon the so-called "motivational dynamic model", which provides a multitude of various strategies with positive effects on students' motivation to learn.

    Medical yoga is defined as the use of yoga practices for the prevention and treatment of medical conditions. Beyond the physical elements of yoga, which are important and effective for strengthening the body, medical yoga also incorporates appropriate breathing techniques, mindfulness, and meditation in order to achieve the maximum benefits. Multiple studies have shown that yoga can positively impact the body in many ways, including helping to regulate blood glucose levels, improve musculoskeletal ailments and keeping the cardiovascular system in tune. It also has been shown to have important psychological benefits, as the practice of yoga can help to increase mental energy and positive feelings, and decrease negative feelings of aggressiveness, depression and anxiety.

    Users of medical information systems need confidence in the security of the system they are using. They also need a method to evaluate and compare its security capabilities. Every system has its own requirements for maintaining confidentiality, integrity and availability. In order to meet these requirements a number of security functions must be specified covering areas such as access control, auditing, error recovery, etc. Appropriate confidence in these functions is also required. The 'trust' in trusted computer systems rests on their ability to prove that their secure mechanisms work as advertised and cannot be disabled or diverted. The general framework and requirements for medical database security and a number of parameters of the evaluation problem are presented and discussed. The problem of database security evaluation is then discussed, and a number of specific proposals are presented, based on a number of existing medical database security systems.

    Medical, dental, nursing, and biomedical personnel often perform critical research that can lead to patents. Similarly, patentable discoveries can be made during the normal course of medical practice, e.g., the development of new biocompatible polymers, improved dental materials, new or modified catheters, new laboratory diagnostic tests, and improved medical devices. Many inventions may not be patented in federal organizations due to the lack of information available on the patenting process. In this article, the financial benefits that can be derived from patenting inventions are discussed, as well as the different types of patents that can be obtained, the conditions for patentability, bars or restrictions to obtaining a patent, the importance of proper record keeping, and the steps to take toward getting an invention patented.

    High altitude is an environment that is alien to man. Stressors associated with the mechanics of flight include motion and acceleration forces applied in three vectors and in degrees that are foreign to the human vestibular apparatus. Furthermore, the work patterns of a pilot can interfere with lifestyle and circadian rhythms. Therefore medical fitness is an important consideration in determining an individual's suitability to exercise a pilot's licence. The medical standards applied depend on the type of aircraft flown and the duties expected of a pilot. There are three broad categories of pilot. In ascending order of stringency of medical standards these are the private pilot, the professional pilot and the military pilot. PMID:7494767

  12. The medicalization of love.

    Pharmaceuticals or other emerging technologies could be used to enhance (or diminish) feelings of lust, attraction, and attachment in adult romantic partnerships. Although such interventions could conceivably be used to promote individual (and couple) well-being, their widespread development and/or adoption might lead to the 'medicalization' of human love and heartache--for some, a source of a serious concern. In this essay, we argue that the medicalization of love need not necessarily be problematic, on balance, but could plausibly be expected to have either good or bad consequences depending upon how it unfolds. By anticipating some of the specific ways in which these technologies could yield unwanted outcomes, bioethicists and others can help to direct the course of love's medicalization--should it happen to occur--more toward the 'good' side than the 'bad.'

  13. Medical examiner variability.

    There are undoubtedly many factors that contribute to inter-examiner variability relevant to the use of medical practitioners in justiciable matters. One source of variability with regard to claims relating to hearing disorders could well be the training and 'calibration' of medical examiners. A tentative analysis of the examination papers and of the declared roles of the specialties that provide these examiners lends support to such a thesis. One solution would be to train special specialists for medicolegal work, as envisaged by Boyarsky for forensic urology (Boyarsky, 1996). At the same time there is the need to change the role-perception of many examiners. There is also the need for medical examiners to express honest, unbiased opinions. There are also problems inherent in the litigation process which does not promote the interactive and adaptive processes between experts that characterise scientific discussions and enquiry.

  14. Exploring medical identity theft.

    2009-09-16

    The crime of medical identity theft is a growing concern in healthcare institutions. A mixed-method study design including a two-stage electronic survey, telephone survey follow-up, and on-site observations was used to evaluate current practices in admitting and registration departments to reduce the occurrence of medical identity theft. Survey participants were chief compliance officers in acute healthcare organizations and members of the Health Care Compliance Association. Study results indicate variance in whether or how patient identity is confirmed in healthcare settings. The findings of this study suggest that information systems need to be designed for more efficient identity management. Admitting and registration staff must be trained, and compliance with medical identity theft policies and procedures must be monitored. Finally, biometric identity management solutions should be considered for stronger patient identification verification.

  15. Refusal to medical interventions.

    Refusal to medical interventions is the not acceptance, voluntary and free, of an indicated medical intervention. What the physician should do in case of refusal? It is understandable that the rejection of a validated medical intervention is difficult to accept by the responsible physician when raises the conflict protection of life versus freedom of choice. Therefore it is important to follow some steps to incorporate the most relevant aspects of the conflict. These steps include: 1) Give complete information to patients, informing on possible alternatives, 2) determine whether the patient can decide (age, competency and level of capacity), 3) to ascertain whether the decision is free, 4) analyze the decision with the patient, 5) to persuade, 6) if the patient kept in the rejection decision, consider conscientious objection, 7) take the decision based on the named criteria, 8) finally, if the rejection is accepted, offer available alternatives.

  16. Adolf Hitler's medical care.

    2005-02-01

    For the last nine years of his life Adolf Hitler, a lifelong hypochondriac had as his physician Dr Theodor Morell. Hitler's mood swings, Parkinson's disease, gastro-intestinal symptoms, skin problems and steady decline until his suicide in 1945 are documented by reliable observers and historians, and in Morell's diaries. The bizarre and unorthodox medications given to Hitler, often for undisclosed reasons, include topical cocaine, injected amphetamines, glucose, testosterone, estradiol, and corticosteroids. In addition, he was given a preparation made from a gun cleaner, a compound of strychnine and atropine, an extract of seminal vesicles, and numerous vitamins and 'tonics'. It seems possible that some of Hitler's behaviour, illnesses and suffering can be attributed to his medical care. Whether he blindly accepted such unorthodox medications or demanded them is unclear.

    2015-01-01

    Carpal tunnel syndrome (CTS) is very rare in children and has been reported very infrequently in the literature. We present an unusual case of CTS in a 14-year-old girl who developed this following an accidental electrical shock. As far as we are aware, this is the first case report of CTS in a child following electrical injury. This rare complication of electrical injury can easily be disregarded or misdiagnosed as neuropraxia, and this can delay appropriate treatment, as evidenced by this case. We propose that CTS should be considered when instigating initial medical care after an electrical injury, and that a referral to a hand surgeon should not be delayed, as these children need urgent surgical intervention to preserve hand function.

  18. Political and medical views on medical marijuana and its future.

    PubMed

    Rubens, Muni

    2014-01-01

    The policies, laws, politics, public opinions, and scientific inferences of medical marijuana are rapidly changing as the debate on medical use of marijuana has always been political, rather than scientific. Federal law has barred the use of medical marijuana though 18 state governments and Washington, DC, support the medical use of marijuana. Unfortunately, not many studies exist on medical marijuana to back these laws and policies. The judiciary, on the other hand, has elicited a diverse response to medical marijuana through its rulings over several decades. Some rulings favored the federal government's opinion, and others supported the larger public view and many state governments with legalized medical marijuana. Public opinion on legalizing medical marijuana has always favored the use of medical marijuana. The movement of scientific knowledge of medical marijuana follows an erratic, discontinuous pathway. The future place of medical marijuana in U.S. society remains unknown. The three forces-scientific knowledge, social-political acceptance, and laws-play a role in the direction that medical marijuana takes in society. Overcoming political-social forces requires a concerted effort from the scientific community and political leaders. The results of scientific research must guide the decisions for laws and medical use of marijuana. This article aims to trace the political dilemma and contradictory views shared by federal and state governments and predict the future of medical marijuana by tracing the past history of medical marijuana with its bumpy pathway in the social-political arena.

    In modern times, the development and exchange of scientific research were promoted greatly by establishments of scientific societies in the west. In the second half of the 17(th) century, medical societies such as the Berlin Royal Society of Medicine, the Paris Surgical Society, the Edinburgh Medical Society and the London Medical Society appeared in sequence, which promoted the progress of European medicine greatly by means of medical conferences and journals. At the end of the 19(th) century, in order to promote medical missions and education, western missionaries drew lessons from the medical society system and founded the China Medical Missionary Association (CMMA). The association was dedicated to work in four fields: terminology standardization, missionary hospitals, medical education and study on endemic disease. CMMA accelerated the development of medical missions and the spread of western medicine. As members of CMMA must be of religious orders, many scholars were not qualified to join in, which resulted in limitation of academic research and exchange. With the return of overseas students, Chinese scholars majoring in western medicine enhanced the awareness of medical knowledge. As a result, western medical societies were established one by one, including the Shanghai Medical Association, the Chinese Pharmaceutical Association, the Chinese Medical Association and the Society of Chinese Medicines of the Republic of China. Established in 1915, the Chinese Medical Association had members who also belonged to the CMMA, so the Chinese Medical Association made reference to the CMMA for its organization, function, operating mechanism, journals, etc..

    The Medical Operational Support Team (MOST) was tasked by the JSC Space Medicine and Life Sciences Directorate (SLSD) to incorporate medical simulation into 1) medical training for astronaut-crew medical officers (CMO) and medical flight control teams and 2) evaluations of procedures and resources required for medical care aboard the International Space Station (ISS). Development of evidence-based medical scenarios that mimic the physiology observed during spaceflight will be needed for the MOST to complete these two tasks. The MOST used a human patient simulator, the ISS-like resources in the Medical Simulation Laboratory (MSL), and evidence from space operations, military operations and medical literature to develop space relevant medical scenarios. These scenarios include conditions concerning airway management, Advanced Cardiac Life Support (ACLS) and mitigating anaphylactic symptoms. The MOST has used these space relevant medical scenarios to develop a preliminary space medical training regimen for NASA flight surgeons, Biomedical Flight Controllers (Biomedical Engineers; BME) and CMO-analogs. This regimen is conducted by the MOST in the MSL. The MOST has the capability to develop evidence-based space-relevant medical scenarios that can help SLSD I) demonstrate the proficiency of medical flight control teams to mitigate space-relevant medical events and 2) validate nextgeneration medical equipment and procedures for space medicine applications.

    1992-01-01

    An electrical pump for pumping liquid metals to high pressures in high temperature environments without the use of magnets or moving mechanical parts. The pump employs a non-porous solid electrolyte membrane, typically ceramic, specific to the liquid metal to be pumped. A DC voltage is applied across the thickness of the membrane causing ions to form and enter the membrane on the electrically positive surface, with the ions being neutralized on the opposite surface. This action provides pumping of the liquid metal from one side of the non-porous solid electrolyte membrane to the other.

    A technical review of high reliability electrical terminations for electronic equipment was made. Seven techniques were selected from this review for further investigation, experimental work, and preliminary testing. From the preliminary test results, four techniques were selected for final testing and evaluation. These four were: (1) induction soldering, (2) wire wrap, (3) percussive arc welding, and (4) resistance welding. Of these four, induction soldering was selected as the best technique in terms of minimizing operator errors, controlling temperature and time, minimizing joint contamination, and ultimately producing a reliable, uniform, and reusable electrical termination.

    To satisfy growing environmental regulations, control energy costs, or just to stay competitive, one must improve existing separation technologies and make them more efficient. New challenges in food processing and requirements for novel purification technologies in the biotech industry also will require more efficient separation techniques. This paper discusses some enhanced separation processes based on the application of an electric field in the combined-fields approach. In a combined-fields approach, the emphasis is on the generation of additional driving forces to work simultaneously with the conventional driving force of the process. Here the authors concentrate on the application of an electric field to generate the additional driving force.

    When NASA was established in 1958, it was known that space flight would require efforts beyond those of NASA to ensure the health and safety of our astronauts. On 10 Aug. 1958, a Secretary of Defense memorandum was signed that assigned the first Department of Defense (DOD) Manager to provide support to NASA for Project Mercury. This established a chain of command through the Joint Chiefs of Staff to the Secretary of Defense. The current charter is dated 19 Mar. 1986 and assigns the DOD Manager responsibilities to the Commander and Chief, US Space Command. The DOD Managers charter has many support areas and among them are recovery of astronauts and medical support. Today these efforts support the Space Shuttle and Space Station Programs. Briefly, the program works with each organization tasking the other through a requirements document. Level of care, communications, and recovery requirements are established; NASA and the DOD provide the capability to meet them. NASA is also responsible for the specialized training and equipment needed to meet these requirements. A Shuttle launch a KSC requires an Emergency Medical Services (EMS) coordinator on console to facilitate communications, ensure proper coverage, and coordinate with area hospitals. A contingent of NASA medical personnel are assembled to provide triage and medical support capabilities. The DOD provides medical evacuation (MEDEVAC) helicopters with surgeons and pararescue specialists (PJ's) or emergency medical technicians (EMT's). Each helicopter is equipped with at least one doctor and one PJ/EMT per astronaut crew member. Transoceanic abort landing (TAL) sites and end of mission (EOM) sites have similar structures, with TAL sites utilizing fixed wingg aircraft for MEDEVAC. The DOD also supports contingency planning for the support and return of crew members from the Space Station Freedom. Much of this support has been directed at the recovery of crew members following the landing of an Assured Crew Return

    450 years ago the Renaissance doctor Theophrastus von Hohenheim called Paracelsus (1493-1541) died. Inspite of a famous name and his renowned challenging nature, his way of thinking and his work remain in many parts unknown. His professional ethics revolve around mercy, charity and his passion for medical art. In his book 'Paragranum' he waves the ethics as a virtue into his succint concept of a 'new topical and veritable medical science'. It is the aim to show the Paracelsian professional ethics in its timeless fundamentals, as in its very personal character.

    The demand for clinical use of accelerated heavy charged-particle (proton and light-ion) beams for cancer treatment is now burgeoning worldwide. Clinical trials are underway at more than a dozen accelerators. Several hospital-based accelerator facilities dedicated to radiation treatment of human cancer have been constructed, and their number is growing. Many instruments in medical systems have been developed for modifying extracted particle beams for clinical application, monitoring the delivery of the treatment beams, and controlling the treatment processes to ensure patient safety. These in turn demand new developments of instruments in controlling beam extraction, beam tuning, and beam transportation at the medical systems.

The consequence of having the freedom to request help from any location at any time is that some individuals will use it for the wrong reasons. Present-day dispatchers must serve ever-broadening communities with multiple languages, cultural diversity, and unique health needs.

Included among these are: identification of seizures, treatment of sleep problems, aggressive management of chronic constipation and GERD as well as timely referral for preventive dental care. Due to the scarcity of sub-specialists (Pediatric Neurologist, Developmental Pediatrician, Child Psychiatrist/ Psychologist) managing children with ASD, the primary care physician should likewise be familiar with medication options for challenging behaviors. More importantly, there needs to be a close collaboration and communication between the family, the sub-specialist and the child's primary care physician.

    In Hungary, the National Accreditation Body was established by government in 1995 as an independent, non-profit organization, and has exclusive rights to accredit, amongst others, medical laboratories. The National Accreditation Body has two Specialist Advisory Committees in the health care sector. One is the Health Care Specialist Advisory Committee that accredits certifying bodies, which deal with certification of hospitals. The other Specialist Advisory Committee for Medical Laboratories is directly involved in accrediting medical laboratory services of health care institutions. The Specialist Advisory Committee for Medical Laboratories is a multidisciplinary peer review group of experts from all disciplines of in vitro diagnostics, i.e. laboratory medicine, microbiology, histopathology and blood banking. At present, the only published International Standard applicable to laboratories is ISO/IEC 17025:1999. Work has been in progress on the official approval of the new ISO 15189 standard, specific to medical laboratories. Until the official approval of the International Standard ISO 15189, as accreditation standard, the Hungarian National Accreditation Body has decided to progress with accreditation by formulating explanatory notes to the ISO/IEC 17025:1999 document, using ISO/FDIS 15189:2000, the European EC4 criteria and CPA (UK) Ltd accreditation standards as guidelines. This harmonized guideline provides 'explanations' that facilitate the application of ISO/IEC 17025:1999 to medical laboratories, and can be used as a checklist for the verification of compliance during the onsite assessment of the laboratory. The harmonized guideline adapted the process model of ISO 9001:2000 to rearrange the main clauses of ISO/IEC 17025:1999. This rearrangement does not only make the guideline compliant with ISO 9001:2000 but also improves understanding for those working in medical laboratories, and facilitates the training and education of laboratory staff.

    Religious traditions of medical ethics tend to differ from more secular approaches by stressing limitations on autonomous decision-making, by more positively valuing the experience of suffering, and by drawing on beliefs and values that go beyond empiric verification. I trace the impact of these differences for some of the world's great religious traditions with respect to four issues: (1) religious conscientious objection to medical treatments; (2) end-of life decision-making, including euthanasia, physician-assisted suicide, and the withholding or withdrawing of life-sustaining treatments; (3) definitions of moral personhood (defining life's beginning and end); and (4) human sexuality.
