    2001-10-01

    In the foreseeable future, private companies will manufacture space vehicles with a capacity of transporting tourists into low Earth orbit. Because of the stresses of spaceflight, the effects of microgravity, and limited medical care capability, a system of medical clearance is highly recommended for these space tourists. It is our purpose to establish guidelines for use by private businesses, medical providers, and those planning on being a space tourist. Consequently, a Task Force was organized by the Aerospace Medical Association (AsMA) for the purpose of facilitating safety of passengers, fellow passengers, crew, and flight operations. The guidelines are meant to serve only as a template with the full expectation that exceptions might be made with appropriate rationale. PMID:11601561

    While it has been of general interest for a long time, the issue of a Medical Kit for Commercial Airlines is now close to the top of the priority list because of recent activities in Europe within the Joint Aviation Authorities (JAA) and in the United States at the Congressional Level. The Aerospace Medical Association (AsMA) requested its Air Transport Medicine Committee to review the situation and make recommendations for a basic medical kit for international airlines. After reviewing the contents of existing kits, and the limited amount of available data, a proposal was submitted to and accepted by the AsMA Council. This is just a beginning. The Air Transport Medicine Committee will continue to follow the evolution and periodically adapt the kit accordingly. PMID:9819172

    2004-01-01

    The purpose of this project is to develop a portable, hands free device for emergency medical decision support to be used in remote or confined settings by non-physician providers. Phase I of the project will entail the development of a voice-activated device that will utilize an intelligent algorithm to provide guidance in establishing an airway in an emergency situation. The interactive, hands free software will process requests for assistance based on verbal prompts and algorithmic decision-making. The device will allow the CMO to attend to the patient while receiving verbal instruction. The software will also feature graphic representations where it is felt helpful in aiding in procedures. We will also develop a training program to orient users to the algorithmic approach, the use of the hardware and specific procedural considerations. We will validate the efficacy of this mode of technology application by testing in the Johns Hopkins Department of Emergency Medicine. Phase I of the project will focus on the validation of the proposed algorithm, testing and validation of the decision making tool and modifications of medical equipment. In Phase 11, we will produce the first generation software for hands-free, interactive medical decision making for use in acute care environments.

    Almost every doctor who visits England comes back wanting to write an article or give a speech about socialized medicine. Because there has been so much said so many times on the subject, it has lost much of its interest. Yet, the headquarters of the California Academy of General Practice in San Francisco recently had a visitor from England who had some startling, frightening things to say of interest to every American doctor. The visitor was Dr. Alastair J. Marshall, Luton, England, who is visiting in this country under a Ford Foundation Grant. As an area executive in the British Medical Association and on the executive area council (one-third physicians, two-thirds laymen) for the national health system, Dr. Marshall can competently speak on this subject. Here are some of the questions presented to Dr. Marshall by the Academy's Executive Secretary Bill Rogers. PMID:18732196

    A narrowband digital speech communication test facility has been established and operates between Lincoln Laboratory and the Wright-Patterson Aerospace Medical Research Laboratory. Noise fields simulating the acoustic environments of E3A and F-15 aircraft are established and Air Force personnel use the link operating at 2400 bps with a vocoder designed at Lincoln Laboratory, and a commercial telephone line modem. The facility includes a digital signal processing computer which can introduce bit errors and delay into the transmit and receive data. Communication scenarios are used to exercise the vocoder-modem channel with the dynamics and vocabulary of typical operational exchanges. Answers to a standard questionnaire provide acceptability data for the 2400 bps JTIDS class 2 voice channel. For the tests run so far, the 2400 bps voice is acceptable in the sense of positive user response to the questionnaire. Further testing using error and delay simulations will follow. An F-15 to F-15 link will be simulated at AMRL using a pair of vocoders operating back-to-back and in separate noise chambers.

    The Polish Medical Association, founded in 1944 in London and celebrating its Golden Jubilee in 1944, is a unique organisation of doctors brought together by the shared experience of serving in the Polish armed forces on the fronts of the II World War. Preparing themselves for the return to a free Poland and later facing the realities of the emigré existence, they formed an association based on an identity with patriotic ideals and espousing a loyalty to the national cause, solidarity with the aspirations and goals of the expatriate community and commitment to the integrity in the performance of their professional duties. It was created against a background of the already existing Polish Medical Faculty at the University of Edinburgh and supported by strong lobbying on the part of the Polish Government and the favourable political climate. The need for a professional body of Polish doctors became evident. During the first few years the Association, originally called the Polish Medical Association in the British Empire, numbered over 700 doctors and achieved notable succeses for its members. The most significant were the endeavours which contributed to the inclusion of the so-called Clause 5 of the Polish Resettlement Act 1947, which in practice allowed Polish doctors serving in the Polish forces under British command to obtain full medical registration. Almost 800 doctors benefitted from this legislature and by coincidence, with the introduction of the National Health Service, they constituted the single most significant injection of non-British doctors into the British health care system. Throughout the years the Association, which originally comprised doctors with an Army background acquired more and more civilian members. The second generation followed, smaller waves of post-war emigration brought in new members from Poland. With time the administrative structure of the Association--initially comprising ten divisions in the UK and overseas--has changed; the

  15. Development of Methodologies for the Estimation of Thermal Properties Associated with Aerospace Vehicles

    1996-01-01

    A thermal stress analysis is an important aspect in the design of aerospace structures and vehicles such as the High Speed Civil Transport (HSCT) at the National Aeronautics and Space Administration Langley Research Center (NASA-LaRC). These structures are complex and are often composed of numerous components fabricated from a variety of different materials. The thermal loads on these structures induce temperature variations within the structure, which in turn result in the development of thermal stresses. Therefore, a thermal stress analysis requires knowledge of the temperature distributions within the structures which consequently necessitates the need for accurate knowledge of the thermal properties, boundary conditions and thermal interface conditions associated with the structural materials. The goal of this proposed multi-year research effort was to develop estimation methodologies for the determination of the thermal properties and interface conditions associated with aerospace vehicles. Specific objectives focused on the development and implementation of optimal experimental design strategies and methodologies for the estimation of thermal properties associated with simple composite and honeycomb structures. The strategy used in this multi-year research effort was to first develop methodologies for relatively simple systems and then systematically modify these methodologies to analyze complex structures. This can be thought of as a building block approach. This strategy was intended to promote maximum usability of the resulting estimation procedure by NASA-LARC researchers through the design of in-house experimentation procedures and through the use of an existing general purpose finite element software.

    The objective of the Research Triangle Institute Technology Transfer Team is to assist NASA in achieving widespread utilization of aerospace technology in terrestrial applications. Widespread utilization implies that the application of NASA technology is to benefit a significant sector of the economy and population of the Nation. This objective is best attained by stimulating the introduction of new or improved commercially available devices incorporating aerospace technology. A methodology is presented for the team's activities as an active transfer agent linking NASA Field Centers, industry associations, user groups, and the medical community. This methodology is designed to: (1) identify priority technology requirements in industry and medicine, (2) identify applicable NASA technology that represents an opportunity for a successful solution and commercial product, (3) obtain the early participation of industry in the transfer process, and (4) successfully develop a new product based on NASA technology.

    The National Aerospace Plane is a horizontal takeoff and landing, single stage-to-orbit vehicle using hydrogen fuel. The first flights are planned for the mid 1990's. The success of this important national program requires advances in virtually every discipline associated with both airbreathing and space flight. The high heating value, cooling capacity, and combustion properties make hydrogen the fuel of choice, but low density results in a large vehicle. Both fuel cooling capacity and density are increased with the use of slush hydrogen and result in significant reductions in vehicle size. A national program to advance this technology and to find engineering solutions to the many design issues is now under way. The program uses the expertise of the cryogenics production and services industry, the instrumentation industry, universities and governments. The program will be discussed to highlight the major issues and display progress to date.

    Almost 2 billion people travel aboard commercial airlines every year. Health-care providers and travellers need to be aware of the potential health risks associated with air travel. Environmental and physiological changes that occur during routine commercial flights lead to mild hypoxia and gas expansion, which can exacerbate chronic medical conditions or incite acute in-flight medical events. The association between venous thromboembolism and long-haul flights, cosmic-radiation exposure, jet lag, and cabin-air quality are growing health-care issues associated with air travel. In-flight medical events are increasingly frequent because a growing number of individuals with pre-existing medical conditions travel by air. Resources including basic and advanced medical kits, automated external defibrillators, and telemedical ground support are available onboard to assist flight crew and volunteering physicians in the management of in-flight medical emergencies.

    1994-01-01

    Thermal stress analyses are an important aspect in the development of aerospace vehicles at NASA-LaRC. These analyses require knowledge of the temperature distributions within the vehicle structures which consequently necessitates the need for accurate thermal property data. The overall goal of this ongoing research effort is to develop methodologies for the estimation of the thermal property data needed to describe the temperature responses of these complex structures. The research strategy undertaken utilizes a building block approach. The idea here is to first focus on the development of property estimation methodologies for relatively simple conditions, such as isotropic materials at constant temperatures, and then systematically modify the technique for the analysis of more and more complex systems, such as anisotropic multi-component systems. The estimation methodology utilized is a statistically based method which incorporates experimental data and a mathematical model of the system. Several aspects of this overall research effort were investigated during the time of the ASEE summer program. One important aspect involved the calibration of the estimation procedure for the estimation of the thermal properties through the thickness of a standard material. Transient experiments were conducted using a Pyrex standard at various temperatures, and then the thermal properties (thermal conductivity and volumetric heat capacity) were estimated at each temperature. Confidence regions for the estimated values were also determined. These results were then compared to documented values. Another set of experimental tests were conducted on carbon composite samples at different temperatures. Again, the thermal properties were estimated for each temperature, and the results were compared with values obtained using another technique. In both sets of experiments, a 10-15 percent off-set between the estimated values and the previously determined values was found. Another effort

    Objective Despite evidence indicating therapeutic benefit for adhering to a prescribed regimen, many patients do not take their medications as prescribed. Non-adherence often leads to morbidity and to higher health care costs. The objective of the study was to assess patient characteristics associated with medication adherence across eight diseases. Design Retrospective data from a repository within an integrated health system was used to identify patients ≥18 years of age with ICD-9-CM codes for primary or secondary diagnoses for any of eight conditions (depression, hypertension, hyperlipidemia, diabetes, asthma or chronic obstructive pulmonary disease, multiple sclerosis, cancer, or osteoporosis). Electronic pharmacy data was then obtained for 128 medications used for treatment. Methods Medication possession ratios (MPR) were calculated for those with one condition and one drug (n=15,334) and then for the total population having any of the eight diseases (n=31,636). The proportion of patients adherent (MPR ≥80%) was summarized by patient and living-area (census) characteristics. Bivariate associations between drug adherence and patient characteristics (age, sex, race, education, and comorbidity) were tested using contingency tables and chi-square tests. Logistic regression analysis examined predictors of adherence from patient and living area characteristics. Results Medication adherence for those with one condition was higher in males, Caucasians, older patients, and those living in areas with higher education rates and higher income. In the total population, adherence increased with lower comorbidity and increased number of medications. Substantial variation in adherence was found by condition with the lowest adherence for diabetes (51%) and asthma (33%). Conclusions The expectation of high adherence due to a covered pharmacy benefit, and to enhanced medication access did not hold. Differences in medication adherence were found across condition and by

    Birth defects may originate through multiple mechanisms and may be caused by a variety of possible exposures, including medications in early pregnancy. In this review, we describe six principal teratogenic mechanisms suspected to be associated with medication use: folate antagonism, neural crest cell disruption, endocrine disruption, oxidative stress, vascular disruption, and specific receptor- or enzyme-mediated teratogenesis. Knowledge about these mechanisms, for some of which evidence is mainly derived from animal models, may not only be relevant for etiologic and post-marketing research, but may also have implications for prescribing behavior for women of reproductive age. Since combinations of seemingly unrelated medications may have effects through similar teratogenic mechanisms, the risk of birth defects may be strongly increased in multi-therapy. PMID:24698184

    The available literature shows us that "Druztvo ljeciteljah u Zagrebus (the Society of Healers in Zagreb) was founded as far back as the year 1845 by a total of thirteen members. This data allows us to follow the role of doctors and health workers in Zagreb through their everyday profession, research, organizational and social work as well as management through a period of over one hundred to seventy years. The Branch Zagreb was active before the official establishment of subsidiaries of CMA which is evident from the minutes of the regular annual assembly of the Croatian Medical Association on 21 March 1948. Until the end of 1956, there was no clear division of labor, functions and competencies between the Branch and the Main Board. Their actions were instead consolidated and the Branch operated within and under the name of Croatian Medical Association. In that year the Branch became independent. The Branch Zagreb is the largest and one of the most active branches of the Croatian Medical Association. At the moment, the Branch brings together 3621 members, regular members--doctors of medicine (2497), doctors of dental medicine (384), retired physicians (710), and associate members (30 specialists with higher education who are not doctors). The Branch is especially accomplished in its activities in the area of professional development of its members and therefore organizes a series of scientific conferences in the framework of continuous education of physicians, allowing its members to acquire necessary points for the extension of their operating license. The choir "Zagrebacki lijecnici pjevaci" (Zagreb Physicians' Choir) of the Croatian Medical Music Society of the CMA and its activities are inseparable from the Branch Zagreb. The Branch is firmly linked to the parent body, the CMA, and thus has a visible impact on the strategy and the activities of the Association as a whole.

Geoscientists working with medical researchers and public health scientists have made important contributions to understanding novel exposure pathways and causes of a wide range of environmental health problems such as: exposure to toxic levels of trace essential and non-essential elements such as arsenic and mercury; trace element deficiencies; exposure to natural dusts and to radioactivity; naturally occurring organic compounds in drinking water; volcanic emissions, etc. By linking with biomedical/public health researchers geoscientists are finally taking advantage of this age-old opportunity to help mitigate environmental health problems. The International Medical Geology Association has recently been formed to support this effort.

    A self-reported measure of four domains of work impairment based on the Work Limitations Questionnaire was completed by 16,651 employees of a large financial services corporation. Using a multivariate model to control for coexisting conditions, age, and gender, significant relationships were observed between medical conditions and patterns of impaired work performance. Depression was highly associated with work limitations in time management (odds ratio [OR] = 2.05), interpersonal/mental functioning (OR = 2.50), and overall output (OR = 2.24). Arthritis (OR = 1.56) and low back pain (OR = 1.32) were associated with physical function limitations. These same two conditions were associated with limitations in mental/interpersonal functioning but with low back pain having the higher odds ratio (OR = 1.54 vs. 1.22). These results suggest that worksite interventions (eg, disease management programs) should be tailored to the unique effects observed with specific medical conditions. More targeted programs could have important benefits for productivity in the workplace. PMID:15194894

  1. Manufacturing Challenges Associated with the Use of Metal Matrix Composites in Aerospace Structures

    Metal Matrix Composites (MMCs) consist of a metal alloy reinforced with ceramic particles or fibers. These materials possess a very high strength to weight ratio, good resistance to impact and wear, and a number of other properties which make them attractive for use in aerospace and defense applications. MMCs have found use in the space shuttle orbiter's structural tubing, the Hubble Space Telescope's antenna mast, control surfaces and propulsion systems for aircraft, and tank armors. The size of MMC components is severely limited by difficulties encountered in joining these materials using fusion welding. Melting of the material results in formation of an undesirable phase (formed when molten Aluminum reacts with the reinforcement) which leaves a strength depleted region along the joint line. Friction Stir Welding (FSW) is a relatively nascent solid state joining technique developed at The Welding Institute (TWI) in 1991. The process was first used at NASA to weld the super lightweight external tank for the Space Shuttle. Today FSW is used to join structural components of the Delta IV, Atlas V, and Falcon IX rockets as well as NASA's Orion Crew Exploration Vehicle and Space Launch System. A current focus of FSW research is to extend the process to new materials, such as MMCs, which are difficult to weld using conventional fusion techniques. Since Friction Stir Welding occurs below the melting point of the workpiece material, this deleterious phase is absent in FSW-ed MMC joints. FSW of MMCs is, however, plagued by rapid wear of the welding tool, a consequence of the large discrepancy in hardness between the steel tool and the reinforcement material. This chapter summarizes the challenges encountered when joining MMCs to themselves or to other materials in structures. Specific attention is paid to the influence of process variables in Friction Stir Welding on the wear process characterizes the effect of process parameters (spindle speed, traverse rate, and length

    On June 26, 2007, Ronald M. Davis, MD, was inaugurated as the 162nd president of the American Medical Association at an ornate ceremony in the Grand Ballroom of the Hilton Chicago Hotel. He is the first AMA president to be board-certified in preventive medicine. After Dr. Davis completed the Epidemic Intelligence Service program and the preventive medicine residency program at the U.S. Centers for Disease Control and Prevention, he served as director of CDC's Office on Smoking and Health and then as medical director of the Michigan Department of Public Health. Since 1995, he has served as director of the Center for Health Promotion and Disease Prevention at the Henry Ford Health System in Detroit. By tradition, the presidents of state medical societies and the leaders of a few other medical organizations sit on the dais during the AMA president's inaugural speech. Reflecting Dr. Davis's interest in strengthening the partnership between clinical medicine and public health, he invited leaders of seven preventive medicine and public health organizations to join him on the dais during his address: the Aerospace Medical Association, the American Association of Public Health Physicians, the American College of Occupational and Environmental Medicine, the American College of Preventive Medicine, the American Public Health Association, the Association of State and Territorial Health Officials, and the National Association of County and City Health Officials. Dr. Davis's inaugural address appears below, except for a portion at the beginning in which he gave tribute to many family members, friends, and colleagues for their support through the years.

    The relevancy of gerontology and geriatrics to the discipline of aerospace medicine is examined. It is noted that since the shuttle program gives the facility to fly passengers, including specially qualified older persons, it is essential to examine response to acceleration, weightlessness, and re-entry over the whole adult lifespan, not only its second quartile. The physiological responses of the older person to weightlessness and the return to Earth gravity are reviewed. The importance of the use of the weightless environment to solve critical problems in the fields of fundamental gerontology and geriatrics is also stressed.

    Objective: This article presents some limited results from the Medical Library Association (MLA) Benchmarking Network survey conducted in 2002. Other uses of the data are also presented. Methods: After several years of development and testing, a Web-based survey opened for data input in December 2001. Three hundred eighty-five MLA members entered data on the size of their institutions and the activities of their libraries. The data from 344 hospital libraries were edited and selected for reporting in aggregate tables and on an interactive site in the Members-Only area of MLANET. The data represent a 16% to 23% return rate and have a 95% confidence level. Results: Specific questions can be answered using the reports. The data can be used to review internal processes, perform outcomes benchmarking, retest a hypothesis, refute a previous survey findings, or develop library standards. The data can be used to compare to current surveys or look for trends by comparing the data to past surveys. Conclusions: The impact of this project on MLA will reach into areas of research and advocacy. The data will be useful in the everyday working of small health sciences libraries as well as provide concrete data on the current practices of health sciences libraries. PMID:16636703

    2015-01-01

    Background: Medication use is associated with falls in many populations, but the relationship between medications and falls in people with multiple sclerosis (MS) is not well understood. Methods: The number and types of medications used by 248 ambulatory adults with MS in the United States (n = 53) and Australia (n = 195) were assessed. Participants completed fall diaries for 6 months. Associations between number and type of medications reported and falls, adjusting for age, disease severity, comorbidities, sex, and country, were evaluated using multiple logistic regression. Results: Participants reported taking a median of three medications and two supplements. A total of 143 participants (58%) fell at least once in the 6 months, and 110 (44%) experienced one or more injurious falls. The adjusted relative odds of a fall or an injurious fall increased by 13% (P = .048) and 11% (P = .049), respectively, for each medication and by 43% (P = .015) and 55% (P = .001) for each neurologically active medication. Reported use of MS disease-modifying therapy was associated with 48% decreased odds of falling (P = .035) but not significantly decreased odds of injurious falls. Conclusions: Reporting use of more medications and more neurologically active medications is associated with falls and injurious falls in people with MS. Close evaluation of the need for each medication, with associated minimization of neurologically active medications in patients with MS, may help prevent falls. Use of MS disease-modifying therapies may be associated with fewer falls. This relationship needs further evaluation. PMID:26472941

    Financial relationships among the biomedical industries, physicians, and professional medical associations (PMAs) can be professional, ethical, mutually beneficial, and, most importantly, can lead to improved medical care. However, such relationships, by their very nature, present conflicts of interest (COIs). One of the greatest concerns regarding COI is continuing medical education (CME), especially because currently industry funds 40-60% of CME. COIs have the potential to bias physicians in practice, educators, and those in leadership positions of PMAs and well as the staff of a PMA. These conflicts lead to the potential to bias the content and type of CME presentations and thereby influence physicians' practice patterns and patient care. Physicians are generally aware of the potential for bias when industry contributes funding for CME, but they are most often unable to detect the bias. This may because it is very subtle and/or the educators themselves may not realize that they have been influenced by their relationships with industry. Following Accreditation Council for Continuing Medical Education guidelines and mandating disclosure that is transparent and complete have become the fallback positions to manage COIs, but such disclosure does not really mitigate the conflict. The eventual and best solutions to ensure evidence-based education are complete divestment by educators and leaders of PMAs, minimal and highly controlled industry funding of PMAs, blind pooling of any industry contributions to PMAs and CME, strict verification of disclosures, clear separation of marketing from education at CME events, and strict oversight of presentations for the presence of bias.

    Problems paying medical bills have been reported to be associated with increased stress, bankruptcy, and forgone medical care. Using the Behavioral Model for Vulnerable Populations developed by Gelberg et al as a framework, as well as data from the 2010 Ohio Family Health Survey, this study examined the relationships between difficulty paying medical bills and forgone medical and prescription drug care. Logistic regression was used to examine associations between difficulty paying medical bills and predisposing, enabling, need (health status), and health behaviors (forgoing medical care). Difficulty paying medical bills increased the effect of lack of health insurance in predicting forgone medical care and had a conditional effect on the association between education and forgone prescription drug care. Those who had less than a bachelor's degree were more likely to forgo prescription drug care than those with a bachelor's degree, but only if they had difficulty paying medical bills. Difficulty paying medical bills also accounted for the relationships between several population characteristics (eg, age, income, home ownership, health status) in predicting forgone medical and prescription drug care. Policies to cap out-of-pocket medical expenses may mitigate health disparities by addressing the impact of difficulty paying medical bills on forgone care. PMID:25856468

  11. Aerospace toxicology overview: aerial application and cabin air quality.

    PubMed

    Chaturvedi, Arvind K

    2011-01-01

    Aerospace toxicology is a rather recent development and is closely related to aerospace medicine. Aerospace toxicology can be defined as a field of study designed to address the adverse effects of medications, chemicals, and contaminants on humans who fly within or outside the atmosphere in aviation or on space flights. The environment extending above and beyond the surface of the Earth is referred to as aerospace. The term aviation is frequently used interchangeably with aerospace. The focus of the literature review performed to prepare this paper was on aerospace toxicology-related subject matters, aerial application and aircraft cabin air quality. Among the important topics addressed are the following: · Aerial applications of agricultural chemicals, pesticidal toxicity, and exposures to aerially applied mixtures of chemicals and their associated formulating solvents/surfactants The safety of aerially encountered chemicals and the bioanalytical methods used to monitor exposures to some of them · The presence of fumes and smoke, as well as other contaminants that may generally be present in aircraft/space vehicle cabin air · And importantly, the toxic effects of aerially encountered contaminants, with emphasis on the degradation products of oils, fluids, and lubricants used in aircraft, and finally · Analytical methods used for monitoring human exposure to CO and HCN are addressed in the review, as are the signs and symptoms associated with exposures to these combustion gases. Although many agricultural chemical monitoring studies have been published, few have dealt with the occurrence of such chemicals in aircraft cabin air. However, agricultural chemicals do appear in cabin air; indeed, attempts have been made to establish maximum allowable concentrations for several of the more potentially toxic ones that are found in aircraft cabin air. In this article, I emphasize the need for precautionary measures to be taken to minimize exposures to aerially

    Objective To examine the association of patient- and medication-related factors with post-discharge medication errors. Patients and Methods The Vanderbilt Inpatient Cohort Study (VICS) includes adults hospitalized with acute coronary syndromes (ACS) and/or acute decompensated heart failure (ADHF). We measured health literacy, subjective numeracy, marital status, cognition, social support, education, income, depression, global health status, and medication adherence in patients enrolled between October 2011 and August 2012. We used binomial logistic regression to determine predictors of discordance between the discharge medication list and patient-reported list during post-discharge medication review. Results Among 471 patients, mean age was 59 years; mean total number of medications reported was 12; and 17% had inadequate or marginal health literacy. Half (51%) of patients had ≥1 one discordant medication (i.e., appeared either on the discharge or patient-reported list but not both); 27% failed to report a medication on their discharge list; and 36% reported a medication not on their discharge list. Additionally, 59% had a misunderstanding in indication, dose, or frequency in a cardiac medication. In multivariable analyses, higher subjective numeracy (Odds Ratio (OR)=0.81, 95% Confidence Interval (CI) 0.67-0.98) was associated with lower odds of having discordant medications. For cardiac medications, participants with higher health literacy (OR=0.84, CI 0.74-0.95), higher subjective numeracy (OR=0.77, CI 0.63-0.95), and who were female (OR=0.60, CI 0.46-0.78) had lower odds of misunderstandings in indication, dose, or frequency. Conclusion Medication errors are present in approximately half of patients following hospital discharge and are more common among patients with lower numeracy or health literacy. PMID:24998906

    Least association rules are corresponded to the rarity or irregularity relationship among itemset in database. Mining these rules is very difficult and rarely focused since it always involves with infrequent and exceptional cases. In certain medical data, detecting these rules is very critical and most valuable. However, mathematical formulation and evaluation of the new proposed measurement are not really impressive. Therefore, in this paper we applied our novel measurement called Critical Relative Support (CRS) to mine the critical least association rules from medical dataset. We also employed our scalable algorithm called Significant Least Pattern Growth algorithm (SLP-Growth) to mine the respective association rules. Experiment with two benchmarked medical datasets, Breast Cancer and Cardiac Single Proton Emission Computed Tomography (SPECT) Images proves that CRS can be used to detect to the pertinent rules and thus verify its scalability.

    2011-04-01

    Clozapine is an atypical antipsychotic agent used for refractory schizophrenia. It has a relatively low affinity for D2 receptors and thus is associated with a lower incidence of extrapyramidal side effects when compared with typical antipsychotics. Clozapine as monotherapy can induce a rare, but serious, blood dyscrasia called agranulocytosis; however, some concomitant medications may contribute to the risk. Examples of these medications are mood-stabilizing antiepileptic drugs, such as carbamazepine, and sulfonamide antibiotics, such as sulfamethoxazole. There were no studies at the writing of this article examining the effect of concomitant medications on clozapine blood dyscrasias, and few published reports describing enhanced bone marrow suppression in those taking clozapine. The primary objective of this study was to evaluate the effect of concomitant medications used in a state psychiatric hospital on clozapine-induced blood dyscrasias. This was a retrospective record review of adverse drug reactions reported at an adult inpatient state psychiatric center. The records for a pilot sample of 26 patients with reported clozapine-related adverse drug reactions between January 1, 2007, and June 30, 2009, were reviewed. Fundamental to this study were reported adverse drug reactions defined as 1) substantial drops in white blood cell or absolute neutrophil count (a substantial drop in white blood cell is >3,000 or absolute neutrophil count is >1,500 over a 3-week period); 2) mild leukopenia/granulocytopenia; and 3) moderate-severe leukopenia/granulocytopenia. Concomitant medications were examined for contributions to an increased potential for clozapine-induced blood dyscrasias. Other data collected included demographic information (age, gender, ethnicity), medical and psychiatric diagnoses, dose and duration of medications, and changes in medications. Medications that had a statistically significant impact on the incidence of clozapine-induced blood dyscrasias are

    Objective: To explore the effect of patient characteristics and health beliefs on their medication adherence. Methods: Patients (n=167) with chronic conditions (mean age 58.9; SD=13.54, 53% males) were recruited from March 2009- to March 2010 using a cross sectional study design. Data collected included patients’ demographics, medical conditions, medications therapeutic regimen, frequency of physician visits and health beliefs. Patient self-reported adherence to medications was assessed by the researcher using a validated and published scale. Treatment related problems (TRPs) were evaluated for each patient by competent clinical pharmacists. Associations between patient characteristics/health beliefs with adherence were explored. Results: About half of the patients (46.1%) were non-adherent. A significant association was found between lower adherence and higher number of disease states (p<0.001), higher number of medications (p=0.001), and higher number of identified TRPs (p = 0.003). Patient adherence was positively affected by older age, higher educational level, and higher number of physician visits per month, while it was negatively affected by reporting difficulties with getting prescription refills on time. Conclusion: This study identified different factors that may negatively affect adherence, including higher number of medications and disease states, higher number of identified TRPs and inability to getting prescription refills on time. Hence, more care needs to be provided to patients with complex therapeutic regimens in order to enhance adherence. PMID:27011772

    Female genital mutilation is the medically unnecessary modification of female genitalia. Female genital mutilation typically occurs at about 7 years of age, but mutilated women suffer severe medical complications throughout their adult lives. Female genital mutilation most frequently occurs in Africa, the Middle East, and Muslim parts of Indonesia and Malaysia, and it is generally part of a ceremonial induction into adult society. Recent political and economic problems in these regions, however, have increased the numbers of students and refugees to the United States. Consequently, US physicians are treating an increasing number of mutilated patients. The Council on Scientific Affairs recommends that US physicians join the World Health Organization, the World Medical Association, and other major health care organizations in opposing all forms of medically unnecessary surgical modification of the female genitalia.

    Background: Stress and its psychological manifestations are currently a major source of concern. Medical education poses challenging and potentially threatening demands for students throughout the world. Objectives: To determine the prevalence and factors associated with perceived stress in medical students in the College of Medicine, King Saud Bin Abdulaziz University for Health Sciences, King Fahad Medical City, Riyadh, Saudi Arabia. Materials and Methods: This was a cross-sectional study on all medical students of batches 9, 10, and 11, which constituted all the enrolled students. Data were collected using a questionnaire based on the Kessler10 psychological distress instrument with a total score ranging from 10 to 50 points in addition to some sociodemographic characteristics. Appropriate statistical test procedures were used to study the magnitude of stress and its risk factors. Results: Mean stress score of the eighty participants was 26.03 ± 9.7. Students with severe stress constituted 33.8%, and 30% were well. Severe stress was significantly associated with female gender and junior level. Nervousness, feeling hopeless, feeling restless, and depressed were the most important factors affecting students’ stress scores. Factor analysis revealed three hidden factors for stress in this group, namely, depression, nervousness, and age. Conclusion: Stress in medical students is prevalent and significantly associated with the female gender and the junior level. Implementation of coping programs is necessary. PMID:27625584

    The World Medical Association was set up in 1947 in the wake of outrage about war crimes committed by doctors in Hitler's Germany. For nearly 50 years it has lurched from one controversy to another, arguing within itself about its funding, its voting system, and the representativeness and political affiliation of some of its member medical associations. The BMA withdrew from the association in 1984, supporting a breakaway "Toronto" group including Canada, the Scandinavian countries, the Netherlands, Ireland, and Jamaica. All but Britain and Jamaica have now rejoined and membership is growing, but the association is still struggling to gain credibility and clout. After 20 years of part time stewardship the recent appointment of a new full time secretary general has fuelled expectations that internal reforms will be implemented, and the WMA's standing and profile improved.

    The medical librarian of 1967 lives in a period of changing concepts, dramatic new methods, everwidening scientific horizons. In looking toward the immediate past he may think of the medical librarian of thirty years ago as a complacent follower of accepted procedures, not as a pioneer in a brave new world. Yet the corps of trained medical librarians today and the resources of our collections and their management are dependent upon the efforts of those who were then pioneers in medical librarianship. Training, standards, recruitment, literature control, international relations, all had continuing attention at a time when financial assistance through government funds, support by administrators, concern by scientists was almost nonexistent. In these years the day of the devoted amateur passed; the trained medical librarian came into being and matured. This, the first Janet Doe Lecture, is named for one who illustrates the best in medical librarianship, serving with scholarly distinction. It is a brief survey pointing to some of the Association's significant achievements during the years of Miss Doe's greatest activity when she and her colleagues met their “Challenge of Change.” PMID:4863973

Yet the corps of trained medical librarians today and the resources of our collections and their management are dependent upon the efforts of those who were then pioneers in medical librarianship. Training, standards, recruitment, literature control, international relations, all had continuing attention at a time when financial assistance through government funds, support by administrators, concern by scientists was almost nonexistent. In these years the day of the devoted amateur passed; the trained medical librarian came into being and matured. This, the first Janet Doe Lecture, is named for one who illustrates the best in medical librarianship, serving with scholarly distinction. It is a brief survey pointing to some of the Association's significant achievements during the years of Miss Doe's greatest activity when she and her colleagues met their "Challenge of Change".

    Background In a prior study, we developed methods for automatically identifying associations between medications and problems using association rule mining on a large clinical data warehouse and validated these methods at a single site which used a self-developed electronic health record. Objective To demonstrate the generalizability of these methods by validating them at an external site. Methods We received data on medications and problems for 263,597 patients from the University of Texas Health Science Center at Houston Faculty Practice, an ambulatory practice that uses the Allscripts Enterprise commercial electronic health record product. We then conducted association rule mining to identify associated pairs of medications and problems and characterized these associations with five measures of interestingness: support, confidence, chi-square, interest and conviction and compared the top-ranked pairs to a gold standard. Results 25,088 medication-problem pairs were identified that exceeded our confidence and support thresholds. An analysis of the top 500 pairs according to each measure of interestingness showed a high degree of accuracy for highly-ranked pairs. Conclusion The same technique was successfully employed at the University of Texas and accuracy was comparable to our previous results. Top associations included many medications that are highly specific for a particular problem as well as a large number of common, accurate medication-problem pairs that reflect practice patterns.

    The Japan Aerospace Exploration Agency (JAXA) provides extravehicular activity (EVA) training to astronauts in a weightless environment test building (WETS) located in Tsukuba City. For EVA training, Tsukuba Medial Center Hospital (TMCH) has established an emergency medical support system, serving as operations coordinator. Taking the perspective of emergency physicians, this paper provides an overview of the medical support system and examines its activities over the past decade as well as future issues. Fortunately, no major accident has occurred during the past 10 years of NBS. Minor complaints (external otitis, acute otitis media, transient dizziness, conjunctival inflammation, upper respiratory inflammation, dermatitis, abraded wounds, etc.) among the support divers have been addressed onsite by attending emergency physicians. Operations related to the medical support system at the WETS have proceeded smoothly for the former NASDA and continue to proceed without event for JAXA, providing safe, high-quality emergency medical services. If an accident occurs at the WETS, transporting the patient by helicopter following initial treatment by emergency physicians can actually exacerbate symptoms, since the procedure exposes a patient who was recently within a hyperbaric environment to the low-pressure environment involved in air transportation. If a helicopter is used, the flight altitude should be kept as low as possible by taking routes over the river. PMID:20703518

    Fragile X syndrome (FXS) is the most common known genetic cause of inherited intellectual disability and the most common known single-gene cause of autism spectrum disorder. It has been reported that a spectrum of medical problems are commonly experienced by people with FXS, such as otitis media, seizures, and gastrointestinal problems. Previous studies examining the prevalence of medical problems related to FXS have been challenging to interpret because of their marked differences in population, setting, and sampling. Through this comprehensive review, we update the literature by reviewing studies that have reported on prominent medical problems associated with FXS. We then compare prevalence results from those studies with results from a large cross-sectional database consisting of data collected by fragile X clinics that specialize in the care of children with FXS and are part of the Fragile X Clinical and Research Consortium. It is vital for pediatricians and other clinicians to be familiar with the medical problems related to FXS so that affected patients may receive proper diagnosis and treatment; improved care may lead to better quality of life for these patients and their families.

    Over a 3-year period, 15 patients with severe hyponatremia were referred to our emergency room from a nearby psychiatric institution. This article reports on 36 episodes of symptomatic hyponatremia in those 15 patients. All but two of the patients were receiving antipsychotic medications; one patient was taking a nonsteroidal anti-inflammatory drug, and one patient was taking an oral hypoglycemic agent. Thirteen patients were chronic schizophrenics, one had a bipolar depressive disorder with psychotic features, and one patient had no psychiatric disorder. Patients presented with seizures, change in mental status, and vegetative symptoms (nausea, vomiting, and diarrhea) associated with hyponatremia and water intoxication. Exacerbation of the patients' underlying illness, psychogenic polydipsia, compulsive smoking, alcoholic cirrhosis, drug abuse, and neuroleptic and other medications are thought to be the major causes of acute hyponatremia in these patients.

    Great controversy surrounds the issue of United States (US) air carrier inflight medical kits. Although there are four medications mandated by the Federal Aviation Administration (FAA) that appeared to be adequate as determined by a 1988 survey, there is now a renewed call to review the medical kit contents with an eye toward making them more robust. This has been prompted by several well publicized inflight medical events and the fact that overseas airlines have a very wide array of pharmaceuticals and supplies. Consequently, the Aerospace Medical Association (AsMA) convened a Task Force of physicians across the major specialties to put forward recommendations regarding medication, medical supplies, and automatic external defibrillators (AEDs). These deliberations were based upon a survey of AsMA physician members. PMID:9773906

    OBJECTIVE To assess factors associated with low adherence to pharmacotherapy in older adults. METHODS Cross-sectional population-based study, with a representative sample of 1,593 individuals aged 60 or older, living in the urban area of Bagé, RS, Southern Brazil, in 2008. A multiple stage sampling model was used. The data were collected through individual household interviews. The analyses of the association between low adherence regarding pharmacotherapy, measured using the Brief Medication Questionnaire (BMQ), and demographic, socioeconomic, behavioral, health, assistance and prescription factors were carried out applying Poisson regression model to assess crude and adjusted prevalence ratios, their respective 95% confidence intervals and p-value (Wald test). RESULTS Around 78.0% of individuals reported have taken at least one medication in the seven days prior to the interview. Of these, approximately one third (28.7%) were considered to have low adherence to the treatment. The factors significantly associated to low adherence to treatment were: age (65 to 74 years old), not having health insurance, having to purchase (totally or partially) their own medicines, having three or more morbidities, having functional disabilities and using three or more medicines. CONCLUSIONS The increased use of medicines by older adults, because of the high prevalence of non-communicable diseases in this group, and the access to the treatment need to be considered by health care professionals regarding fostering adherence to treatment, which increases therapeutic solutions and quality of life among older people.

    Hoffman, Jay R.; Ratamess, Nicholas A.

    2006-01-01

    For the past 50 years anabolic steroids have been at the forefront of the controversy surrounding performance enhancing drugs. For almost half of this time no attempt was made by sports governing bodies to control its use, and only recently have all of the major sports governing bodies in North America agreed to ban from competition and punish athletes who test positive for anabolic steroids. These punitive measures were developed with the primary concern for promotion of fair play and eliminating potential health risks associated with androgenic-anabolic steroids. Yet, controversy exists whether these testing programs deter anabolic steroid use. Although the scope of this paper does not focus on the effectiveness of testing, or the issue of fair play, it is of interest to understand why many athletes underestimate the health risks associated from these drugs. What creates further curiosity is the seemingly well-publicized health hazards that the medical community has depicted concerning anabolic steroidabuse. Is there something that the athletes know, or are they simply naïve regarding the dangers? The focus of this review is to provide a brief history of anabolic steroid use in North America, the prevalence of its use in both athletic and recreational populations and its efficacy. Primary discussion will focus on health issues associated with anabolic steroid use with an examination of the contrasting views held between the medical community and the athletes that are using these ergogenic drugs. Existing data suggest that in certain circumstances the medical risk associated with anabolic steroid use may have been somewhat exaggerated, possibly to dissuade use in athletes. Key Points For many years the scientific and medical communities depicted a lack of efficacy and serious adverse effects from anabolic steroid use. Clinical case studies continue to link anabolic steroid administration with myocardial infarct, suicide, and cancer, evidence to support a cause

    Whether finding new applications for existing NASA technologies or developing unique marketing strategies to demonstrate them, NASA's offices are committed to identifying unique partnering opportunities. Through their efforts NASA leverages resources through joint research and development, and gains new insight into the core areas relevant to all NASA field centers. One of the most satisfying aspects of my job comes when I learn of a mission-driven technology that can be spun-off to touch the lives of everyday people. NASA's New Partnerships in Medical Diagnostic Imaging is one such initiative. Not only does it promise to provide greater dividends for the country's investment in aerospace research, but also to enhance the American quality of life. This issue of Innovation highlights the new NASA-sponsored initiative in medical imaging. Early in 2001, NASA announced the launch of the New Partnerships in Medical Diagnostic Imaging initiative to promote the partnership and commercialization of NASA technologies in the medical imaging industry. NASA and the medical imaging industry share a number of crosscutting technologies in areas such as high-performance detectors and image-processing tools. Many of the opportunities for joint development and technology transfer to the medical imaging market also hold the promise for future spin back to NASA.

    1994-01-01

    The history of health care delivery in Canada has been marked by close collaboration between physicians and the pharmaceutical and health supply industries, this collaboration extending to research as well as to education. Since medicine is a self-governing profession physicians have a responsibility to ensure that their participation in such collaborative efforts is in keeping with their duties toward their patients and society. The following guidelines have been developed by the CMA to assist physicians in determining when a relationship with industry is appropriate. Although directed primarily to individual physicians, including residents and interns as well as medical students, the guidelines also govern the relationships between industry and medical associations. These guidelines focus on the pharmaceutical companies; however, the CMA considers that the same principles apply to the relationship between its members and manufacturers of medical devices, infant formulas and similar products, and health care products and service suppliers in general. These guidelines reflect a national consensus and are meant to serve as an educational resource for physicians throughout Canada. PMID:8287348

    2015-11-01

    The present paper analyses the emergence and characteristics of Israeli Medical Association (IMA) discourse on health inequality in Israel during the years 1977-2010. The IMA addressed the issue of health inequality at a relatively late stage in time (2000), as compared to other OECD countries such as the UK, and did so in a relatively limited way, focusing primarily on professional or economic interests. The dominant discourses on health inequalities within the IMA are biomedical and behavioral, characterized by a focus on medical and/or cultural and behavioral differences, the predominant use of medical terminology, and an individualistic rather than a structural conceptualization of the social characteristics of health differences. Additionally, IMA discourses emphasize certain aspects of health inequality such as the geographical and material inequities, and in doing so overlook the role played by class, nationality and the unequal structure of citizenship. Paradoxically, by disregarding the latter, the IMA's discourse on health inequality has the potential to reinforce the structural causes of these inequities. Our research is based on a textual critical discourse analysis (CDA) of hundreds of documents from the IMA's scientific medical journal, the IMA's members journal and public IMA documents such as press-releases, Knesset protocols, publications, and public surveys. By providing knowledge on the different ways in which the IMA, a key stakeholder in the health field, de-codifies, understands, explains, and attempts to deal with health inequality, the article illuminates possible implications on health policy and seeks to evaluate the direct interventions carried out by the IMA, or by other actors influenced by it, pertaining to health inequality.

    2013-01-01

    Objectives The aim of this study was to demonstrate the existence of systematic associations in drug prescription that lead to the establishment of patterns of polypharmacy, and the clinical interpretation of the associations found in each pattern. Methods A cross-sectional study was conducted based on information obtained from electronic medical records and the primary care pharmacy database in 2008. An exploratory factor analysis of drug dispensing information regarding 79,089 adult patients was performed to identify the patterns of polypharmacy. The analysis was stratified by age and sex. Results Seven patterns of polypharmacy were identified, which may be classified depending on the type of disease they are intended to treat: cardiovascular, depression-anxiety, acute respiratory infection (ARI), chronic obstructive pulmonary disease (COPD), rhinitis-asthma, pain, and menopause. Some of these patterns revealed a clear clinical consistency and included drugs that are prescribed together for the same clinical indication (i.e., ARI and COPD patterns). Other patterns were more complex but also clinically consistent: in the cardiovascular pattern, drugs for the treatment of known risk factors—such as hypertension or dyslipidemia—were combined with other medications for the treatment of diabetes or established cardiovascular pathology (e.g., antiplatelet agents). Almost all of the patterns included drugs for preventing or treating potential side effects of other drugs in the same pattern. Conclusions The present study demonstrated the existence of non-random associations in drug prescription, resulting in patterns of polypharmacy that are sound from the pharmacological and clinical viewpoints and that exist in a significant proportion of the population. This finding necessitates future longitudinal studies to confirm some of the proposed causal associations. The information discovered would further the development and/or adaptation of clinical patient guidelines

  14. Environmentally regulated aerospace coatings

    Morris, Virginia L.

    1995-01-01

    Aerospace coatings represent a complex technology which must meet stringent performance requirements in the protection of aerospace vehicles. Topcoats and primers are used, primarily, to protect the structural elements of the air vehicle from exposure to and subsequent degradation by environmental elements. There are also many coatings which perform special functions, i.e., chafing resistance, rain erosion resistance, radiation and electric effects, fuel tank coatings, maskants, wire and fastener coatings. The scheduled promulgation of federal environmental regulations for aerospace manufacture and rework materials and processes will regulate the emissions of photochemically reactive precursors to smog and air toxics. Aerospace organizations will be required to identify, qualify and implement less polluting materials. The elimination of ozone depleting chemicals (ODC's) and implementation of pollution prevention requirements are added constraints which must be addressed concurrently. The broad categories of operations affected are the manufacture, operation, maintenance, and repair of military, commercial, general aviation, and space vehicles. The federal aerospace regulations were developed around the precept that technology had to be available to support the reduction of organic and air toxic emissions, i.e., the regulations cannot be technology forcing. In many cases, the regulations which are currently in effect in the South Coast Air Quality Management District (SCAQMD), located in Southern California, were used as the baseline for the federal regulations. This paper addresses strategies used by Southern California aerospace organizations to cope with these regulatory impacts on aerospace productions programs. All of these regulatory changes are scheduled for implementation in 1993 and 1994, with varying compliance dates established.

    1992-01-01

    The principle goal of the educational component of NASA CORE is the creation of aerospace engineering options in the mechanical engineering program at both the undergraduate and graduate levels. To accomplish this goal, a concerted effort during the past year has resulted in detailed plans for the initiation of aerospace options in both the BSME and MSME programs in the fall of 1993. All proposed new courses and the BSME aerospace option curriculum must undergo a lengthy approval process involving two cirriculum oversight committees (School of Engineering and University level) and three levels of general faculty approval. Assuming approval is obtained from all levels, the options will officially take effect in Fall '93. In anticipation of this, certain courses in the proposed curriculum are being offered during the current academic year under special topics headings so that current junior level students may graduate in May '94 under the BSME aerospace option. The proposed undergraduate aerospace option curriculum (along with the regular mechanical engineering curriculum for reference) is attached at the end of this report, and course outlines for the new courses are included in the appendix.

    This paper presents selected results from an empirical investigation into the use of computer networks in aerospace engineering. Such networks allow aerospace engineers to communicate with people and access remote resources through electronic mail, file transfer, and remote log-in. The study drew its subjects from private sector, government and academic organizations in the U.S. aerospace industry. Data presented here were gathered in a mail survey, conducted in Spring 1993, that was distributed to aerospace engineers performing a wide variety of jobs. Results from the mail survey provide a snapshot of the current use of computer networks in the aerospace industry, suggest factors associated with the use of networks, and identify perceived impacts of networks on aerospace engineering work and communication.

    The Association for Medical Education and Research in Substance Abuse (AMERSA) is a multi-disciplinary organization committed to health professional faculty development in substance abuse. In 1976, members of the Career Teachers Training Program in Alcohol and Drug Abuse, a US federally funded multi-disciplinary faculty development program, formed AMERSA. The organization grew from 59 founding members, who were primarily medical school faculty, to over 300 health professionals from a spectrum of disciplines including physicians, nurses, social workers, dentists, allied health professionals, psychologists and other clinical educators who are responsible for advancing substance abuse education. AMERSA members promote substance abuse education among health professionals by developing curricula, promulgating relevant policy and training health professional faculty to become excellent teachers in this field. AMERSA influences public policy by offering standards for improving substance abuse education. The organization publishes a peer-reviewed, quarterly journal, Substance Abuse, which emphasizes research on the education and training of health professions and also includes original clinical and prevention research. Each year, the AMERSA National Conference brings together researchers and health professional educators to learn about scientific advances and exemplary teaching approaches. In the future, AMERSA will continue to pursue this mission of advancing and supporting health professional faculty who educate students and trainees to address substance abuse in patients and clients.

    Both diabetes mellitus and cancer are prevalent diseases worldwide. It is evident that there is a substantial increase in cancer incidence in diabetic patients. Epidemiologic studies have indicated that diabetic patients are at significantly higher risk of common cancers including pancreatic, liver, breast, colorectal, urinary tract, gastric and female reproductive cancers. Mortality due to cancer is moderately increased among patients with diabetes compared with those without. There is increasing evidence that some cancers are associated with diabetes, but the underlying mechanisms of this potential association have not been fully elucidated. Insulin is a potent growth factor that promotes cell proliferation and carcinogenesis directly and/or through insulin-like growth factor 1 (IGF-1). Hyperinsulinemia leads to an increase in the bioactivity of IGF-1 by inhibiting IGF binding protein-1. Hyperglycemia serves as a subordinate plausible explanation of carcinogenesis. High glucose may exert direct and indirect effects upon cancer cells to promote proliferation. Also chronic inflammation is considered as a hallmark of carcinogenesis. The multiple drugs involved in the treatment of diabetes seem to modify the risk of cancer. Screening to detect cancer at an early stage and appropriate treatment of diabetic patients with cancer are important to improve their prognosis. This paper summarizes the associations between diabetes and common cancers, interprets possible mechanisms involved, and addresses implications for medical practice. PMID:24936258

    ISSUES: Tobacco Control remains one of the greatest determinants for reducing the morbidity and mortality of African Americans. OBJECTIVE: To examine the scope and consequences of tobacco use among African Americans and characterize its implications for the National Medical Association physician membership and their patients, and identify policy, education, advocacy and research issues in Tobacco Control for the organization. CONSENSUS PROCESS: Literature review using the MEDLINE database from January 1966 to August 1999 Week 1, searching Medical Subject Heading (MeSH) reading combined with text words "Black" or "African American" and "Tobacco" as a search term, identified 130 articles/110 abstracts published between 1988 and February 1999. The panel selected 61 appropriate articles and a paper summarizing the literature review was developed. The summary paper was used as background material for a formal consensus panel discussion on July 16-17, 1999. Consensus among committee members was reached via mail, fax and e-mail using the summary review paper, annotated bibliographies key informant surveys, and previous NMA resolutions on tobacco control. A formal working session was held on July 16-17, 1999 in which four areas of concentration of issues were determined: Policy, Advocacy, Education and Research. All committee members approved the final report. SUMMARY: Because tobacco control issues in African Americans are both complex and poorly understood, the panel views the NMA's role as pivotal in the coordination of resources and capacity-building to address all four areas identified. Stronger partner-ships with traditional federal and nonprofit agencies associated with tobacco control/advocacy in African Americans as well as nontraditional organizations (i.e., churches, academia, marketing and media organizations) also must occur to strengthen the infra-structure needed to assess needs, design appropriate interventions and evaluate the appropriateness

The, at this point largely unexamined, plethora of possibilities going forward, a subset of which is discussed, could literally reinvent aerospace but requires triage of many possibilities. Such initial upfront homework would lengthen the Research and Development (R&D) time frame but could greatly enhance the affordability and performance of the evolved products and capabilities. Structural nanotubes and exotic energetics along with some unique systems approaches are particularly compelling.

    What is already known about this subject Polypharmacy, to include a subissue of potentially inappropriate prescribing, in community-dwelling elderly is widespread. The objective of this study was to identify the magnitude of problematic outpatient drug prescribing and its potential association as a risk factor for injuries. What this study adds This is the first national study of outpatient injuries in elderly veterans. The results are consistent with previous published literature highlighting the risks associated with prescribing central nervous system drugs in the elderly. Aims The primary objective of this retrospective case–control study in an elderly veteran population was to assess the impact of specific medications with recognized side-effects that increase the risk of a fall and were prescribed prior to fractures treated in the outpatient setting compared with patients treated for nonspecific chest pain. Methods Two national Veterans Health Administration (VHA) databases were used to identify 17 273 unique patients, aged ≥65 years, treated in outpatient settings with a fracture in fiscal year 2005, and for whom we could link to all of their outpatient prescriptions (809 536). For comparison, we identified other elderly patients with outpatient clinic visits for nonspecific chest pain (N = 62 331) for whom we could link with their 2 987 394 outpatient prescriptions. We categorized the fall-related medications as drugs that primarily affect the cardiovascular (CVS), the central nervous (CNS) or the muscular skeletal system (MSS). Results Significant differences in the two patient groups occurred in the CNS category. Approximately 41% of the patients with fracture-coded encounters were prescribed CNS drugs compared with 31% of the patients in the comparison group (P < 0.0003). Finally, the use of muscle relaxants in the MSS category was significantly higher in the fracture group than in the nonspecific chest pain group. Conclusions Studies using

    1999-01-01

    This report covers the activities of the Aerospace Safety Advisory Panel (ASAP) for calendar year 1998-a year of sharp contrasts and significant successes at NASA. The year opened with the announcement of large workforce cutbacks. The slip in the schedule for launching the International Space Station (ISS) created a five-month hiatus in Space Shuttle launches. This slack period ended with the successful and highly publicized launch of the STS-95 mission. As the year closed, ISS assembly began with the successful orbiting and joining of the Functional Cargo Block (FGB), Zarya, from Russia and the Unity Node from the United States. Throughout the year, the Panel maintained its scrutiny of NASA's safety processes. Of particular interest were the potential effects on safety of workforce reductions and the continued transition of functions to the Space Flight Operations Contractor. Attention was also given to the risk management plans of the Aero-Space Technology programs, including the X-33, X-34, and X-38. Overall, the Panel concluded that safety is well served for the present. The picture is not as clear for the future. Cutbacks have limited the depth of talent available. In many cases, technical specialties are 'one deep.' The extended hiring freeze has resulted in an older workforce that will inevitably suffer significant departures from retirements in the near future. The resulting 'brain drain' could represent a future safety risk unless appropriate succession planning is started expeditiously. This and other topics are covered in the section addressing workforce. The major NASA programs are also limited in their ability to plan property for the future. This is of particular concern for the Space Shuttle and ISS because these programs are scheduled to operate well into the next century. In the case of the Space Shuttle, beneficial and mandatory safety and operational upgrades are being delayed because of a lack of sufficient present funding. Likewise, the ISS has

  9. Combustion Processes in the Aerospace Environment

    NASA Technical Reports Server (NTRS)

    Huggett, Clayton

    1969-01-01

    The aerospace environment introduces new and enhanced fire hazards because the special atmosphere employed may increase the frequency and intensity of fires, because the confinement associated with aerospace systems adversely affects the dynamics of fire development and control, and because the hostile external environments limit fire control and rescue operations. Oxygen enriched atmospheres contribute to the fire hazard in aerospace systems by extending the list of combustible fuels, increasing the probability of ignition, and increasing the rates of fire spread and energy release. A system for classifying atmospheres according to the degree of fire hazard, based on the heat capacity of the atmosphere per mole of oxygen, is suggested. A brief exploration of the dynamics of chamber fires shows that such fires will exhibit an exponential growth rate and may grow to dangerous size in a very short time. Relatively small quantities of fuel and oxygen can produce a catastrophic fire in a closed chamber.

    1985-01-01

    The industry is hereby challenged to integrate adhesive technology with the total structure requirements in light of today's drive into automation/mechanization. The state of the art of adhesive technology is fairly well meeting the needs of the structural designers, the processing engineer, and the inspector, each on an individual basis. The total integration of these needs into the factory of the future is the next collective hurdle to be achieved. Improved processing parameters to fit the needs of automation/mechanization will necessitate some changes in the adhesive forms, formulations, and chemistries. Adhesives have, for the most part, kept up with the needs of the aerospace industry, normally leading the rest of the industry in developments. The wants of the aerospace industry still present a challenge to encompass all elements, achieving a totally integrated joined and sealed structural system. Better toughness with hot-wet strength improvements is desired. Lower cure temperatures, longer out times, and improved corrosion inhibition are desired.

    Early last year the US Office of Science and Technology put forward an agenda for American aerospace activity in the coming decades. The plan established goals for subsonic, supersonic and transatmospheric hypersonic flight. Those goals, together with Reagan Administration's programs for a space station and the Strategic Defense Initiative, serve as a driving force for extensive improvements in the materials that enable airplanes and spacecraft to function efficiently. The development of materials, together with advances in the technology of fabricating parts, will play a key role in aerospace systems of the future. Among the materials developments projected for the year 2000 are new composites and alloys for structural members; superalloys, ceramics and glass composites for propulsion systems, and carbon-carbon composites (carbon fibers in a carbon matrix) for high-temperature applications in places where resistance to heat and ablation is critical. 5 figures.

    Recent developments indicate that there may soon be a revolution in aerospace structures. Increases in allowable operational stress levels, utilization of high-strength, high-toughness materials, and new structural concepts will highlight this advancement. Improved titanium and aluminum alloys and high-modulus, high-strength advanced composites, with higher specific properties than aluminum and high-strength nickel alloys, are expected to be the principal materials. Significant advances in computer technology will cause major changes in the preliminary design cycle and permit solutions of otherwise too-complex interactive structural problems and thus the development of vehicles and components of higher performance. The energy crisis will have an impact on material costs and choices and will spur the development of more weight-efficient structures. There will also be significant spinoffs of aerospace structures technology, particularly in composites and design/analysis software.

    PubMed

    Larriviere, Daniel G

    2014-10-01

    The number of states legalizing medical marijuana is increasing. Medical marijuana is possibly effective therapy for HIV-associated sensory neuropathy. Despite legalization at the state level, however, the current and contradictory federal drug enforcement policy creates the risk that physicians who recommend medical marijuana to their patients will lose their ability to prescribe medications. The federal-state tension has legal and ethical implications for neurologists who receive a request for medical marijuana from their patients since neurologists must strive to both relieve suffering and obey relevant laws. Recommendation of medical marijuana by neurologists to their patients is ethically permissible but is not ethically mandatory. PMID:25299291

    After the First World War the professional medical societies in Hungary, which have already organized themselves nationwide, started to operate independently from each other. In that time came the idea to create another association above the others to gather them together while retaining their independent functioning. The Association of the Scientific Societies of Hungarian Medical Doctors (MORTESZ), established in 1931, became the nationwide forum for many medical associations. It also organized the first Hungarian Medical Grand-Week which became the annual meeting of the medical society. In the first year the cooperation only consisted of a common topic of two or three associations presented in the "Grand-Week". From year 1935, reports were appointed annually that each professional association could comment on. The proceedings of the "Grand-Week" were published yearly as appendices of the Hungarian Medical Journal. After the Second World War the activities of the independent associations were shut down by the authorities. The scientific and professional associations could continue their work as sections inside of the Doctors and Health Workers' Union. In 1966 the situation was solved thanks to the initiative of the Trade Union, the Department of Medicine and the Medical Section of the Hungarian Academy of Sciences which resulted in the foundation of the Association of the Hungarian Medical Societies (MOTESZ) which continues to gather together the collective work of many scientific associations and carries out tasks of general interest since then, similarly to the now 80-years-old MORTESZ.

    Ambrose, Charles T.

    2005-01-01

    This paper relates the neglected history of an idealistic, secret medical fraternity which existed briefly in Lexington, Kentucky, during the first half of the 19th century. It was created for students in the Medical Department at Transylvania University, the fifth US medical school, founded in 1799. One goal of the fraternity was to counter the widespread dissension and often violent quarrels among doctors that characterized American medicine of that period. And to that end, it was among the first to promote Thomas Percival's code of medical ethics in this country. Branches of the fraternity were established in Philadelphia and New York City, where members became influential in local medical politics but in time encountered hostility from rival physicians. The secret character of the fraternity branches was publicized and maligned during an anti-Masonic movement in this country in the 1830s, which soon led to the demise of the Philadelphia group. The New York branch remained active through the 1860s. Members of both branches were among those who in 1847 established the American Medical Association and devised its Principles of Medical Ethics.

    This paper is about supportability in its general sense, with emphasis on aerospace structures. Reliability and maintainability (R&M) are described and defined from the standpoint of both structural analysis. Accessability, inspectability, and replaceability are described as design attributes. Reliability and probability of failure are shown to be in the domain of the analysis. Availability and replaceability are traditional logistic responsibilities which are influenced by supportability engineers. The USAF R&M 2000 process is described, and the R&M 1988 Workshop at Wright-Patterson Air Force Base is also included in the description.

  7. Trajectory optimization for the National Aerospace Plane

    The objective of this second phase research is to investigate the optimal ascent trajectory for the National Aerospace Plane (NASP) from runway take-off to orbital insertion and address the unique problems associated with the hypersonic flight trajectory optimization. The trajectory optimization problem for an aerospace plane is a highly challenging problem because of the complexity involved. Previous work has been successful in obtaining sub-optimal trajectories by using energy-state approximation and time-scale decomposition techniques. But it is known that the energy-state approximation is not valid in certain portions of the trajectory. This research aims at employing full dynamics of the aerospace plane and emphasizing direct trajectory optimization methods. The major accomplishments of this research include the first-time development of an inverse dynamics approach in trajectory optimization which enables us to generate optimal trajectories for the aerospace plane efficiently and reliably, and general analytical solutions to constrained hypersonic trajectories that has wide application in trajectory optimization as well as in guidance and flight dynamics. Optimal trajectories in abort landing and ascent augmented with rocket propulsion and thrust vectoring control were also investigated. Motivated by this study, a new global trajectory optimization tool using continuous simulated annealing and a nonlinear predictive feedback guidance law have been under investigation and some promising results have been obtained, which may well lead to more significant development and application in the near future.

    In mid-1996, the FDA called for discussions on regulation of clinical software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology has developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. Organizations assisting in development of recommendations, or endorsing the consortium position include the American Medical Informatics Association, the Computer-based Patient Record Institute, the Medical Library Association, the Association of Academic Health Sciences Libraries, the American Health Information Management Association, the American Nurses Association, the Center for Healthcare Information Management, and the American College of Physicians. The consortium proposes four categories of clinical system risks and four classes of measured monitoring and regulatory actions that can be applied strategically based on the level of risk in a given setting. The consortium recommends local oversight of clinical software systems, and adoption by healthcare information system developers of a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively. FDA regulation should exempt most clinical software systems and focus on those systems posing highest clinical risk, with limited opportunities for competent human intervention. PMID:9391932

    Health care practitioners utilize the United States-Food and Drug Administration (US-FDA) pregnancy categorization (A, B, C, D, X) for making decision on the appropriateness of certain medications during pregnancy. Many non US-FDA approved medications are registered and marketed in Saudi Arabia. However, these medications do not have an assigned pregnancy risk categorization like those approved in the US. The objective of this review is to evaluate, report, and categorize the foetal risk associated with non-US-FDA approved medications registered by the Saudi Food and Drug Authority (S-FDA) according to the US-FDA pregnancy risk categorization system. We identified 109 non-US-FDA approved medications in the Saudi National Formulary (SNF) as of October 2007. We searched for data on functional or anatomical birth defects or embryocidal-associated risk using different databases and references. An algorithm for risk assessment was used to determine a pregnancy risk category for each medication. Out of 93 eligible medications, 73% were assigned category risk C, 10 medications (11%) were assigned category risk D, and 12 medications (13%) were assigned category risk B. Only three medications were judged to be safe during pregnancy based on the available evidence and were assigned category risk A. Inconsistencies in defining and reporting the foetal risk category among different drug regulatory authorities could create confusion and affect prescribing. We believe that standardization and inclusion of this information in the medication package insert is extremely important to all health care practitioners. PMID:23960803

    The current study examined adherence to medication regimens among adolescents with cancer by applying the Pediatric Self-Management Model. Adolescents and their parents reported on adherence to medication, reasons for nonadherence, and patient-, family-, and community-level psychosocial variables. Adolescent- and parent-reported adherence were significantly correlated, with about half of the sample reporting perfect adherence. The majority reported "just forgot" as the most common reason for missed medication. Patient-, family-, and community-level variables were examined as predictors of adherence. With regard to individual factors, adolescents who endorsed perfect adherence reported a greater proportion of future-orientated goals and spent fewer days in outpatient clinic visits. For family factors, adolescents who endorsed perfect adherence reported greater social support from their family and were more likely to have a second caregiver who they perceived as overprotective. The community-level variable (social support from friends) tested did not emerge as a predictor of adherence. The results of this study provide direction for intervention efforts to target adolescent goals and family support in order to increase adolescent adherence to cancer treatment regimens.

    2013-03-01

    This study examined the association of mental and medical illnesses with the odds for leaving against medical advice (AMA) in a national sample of adult patients who left general hospitals between 1988 and 2006. Leaving AMA was first examined as a function of year and mental illness. Multiple logistic regression analysis was then used to adjust for patient and hospital characteristics when associating mental and major medical diagnoses with AMA discharges. The results indicated that leaving AMA was most strongly associated with mental health problems. However, the impact of mental illness was attenuated after adjusting for medical illnesses, patient and hospital characteristics. The strongest predictors of AMA discharge included being self-pay, having Medicaid insurance, being young and male, and the regional location of the hospital (Northeast). When substance abuse conditions were excluded from the mental illness discharge diagnoses, mental illness had lower odds for leaving AMA. The results may be of value to clinicians, and hospital administrators in helping to profile and target patients at risk for treatment-compliance problems. Prospective primary data collection that would include patient, physician, and hospital variables is recommended. PMID:22057857

  17. Does the association between prescription copayment increases and medication adherence differ by race?

    PubMed

    Wong, Edwin S; Maciejewski, Matthew L; Liu, Chuan-Fen

    2013-08-01

    Previous studies have shown prescription copayment increases are associated with decreases in adherence to diabetes and hypertension medications, but have not investigated whether these associations differ by race. Veterans Affairs (VA) administrative data were used to analyze medication adherence before and after an increase in prescription copayments from $2 to $7 for a 30-day supply in February 2002. Applying a difference-in-difference approach, we compared adherence changes among White and Black veterans who were exempt from or required to pay medication copayments. The likelihood patients were adherent to diabetes or hypertension medications decreased after the copayment increase for both White and Black veterans. However, differences in medication adherence reductions between White and Black veterans were small and statistically insignificant. Despite barriers faced by minority patients related to lower perceived value of medications, the impact of a copayment increase on adherence was similar across the two largest racial groups in the VA.

    This article reviews military and aerospace developments of 1989. The Voyager spacecraft returned astounding imagery from Neptune, sophisticated sensors were launched to explore Venus and Jupiter, and another craft went into earth orbit to explore cosmic rays, while a huge telescope is to be launched early in 1990. The U.S. space shuttle redesign was completed and access to space has become no longer purely a governmental enterprise. In the military realm, events within the Soviet bloc, such as the Berlin Wall's destruction, have popularized arms control. Several big treaties could be signed within the year. Massive troop, equipment, and budget reductions are being considered, along with a halt or delay of major new weapons systems. For new missions, the U.S. military is retreating to its role of a century ago - patrolling the nation's borders, this time against narcotics traffickers.

  6. Dynamics of aerospace vehicles

    Schmidt, David K.

    1991-01-01

    The focus of this research was to address the modeling, including model reduction, of flexible aerospace vehicles, with special emphasis on models used in dynamic analysis and/or guidance and control system design. In the modeling, it is critical that the key aspects of the system being modeled be captured in the model. In this work, therefore, aspects of the vehicle dynamics critical to control design were important. In this regard, fundamental contributions were made in the areas of stability robustness analysis techniques, model reduction techniques, and literal approximations for key dynamic characteristics of flexible vehicles. All these areas are related. In the development of a model, approximations are always involved, so control systems designed using these models must be robust against uncertainties in these models.

  7. Aerospace Safety Advisory Panel

    NASA Technical Reports Server (NTRS)

    1999-01-01

    This report covers the activities of the Aerospace Safety Advisory Panel (ASAP) for calendar year 1998-a year of sharp contrasts and significant successes at NASA. The year opened with the announcement of large workforce cutbacks. The slip in the schedule for launching the International Space Station (ISS) created a 5-month hiatus in Space Shuttle launches. This slack period ended with the successful and highly publicized launch of the STS-95 mission. As the year closed, ISS assembly began with the successful orbiting and joining of the Functional Cargo Block (FGB), Zarya, from Russia and the Unity Node from the United States. Throughout the year, the Panel maintained its scrutiny of NASAs safety processes. Of particular interest were the potential effects on safety of workforce reductions and the continued transition of functions to the Space Flight Operations Contractor. Attention was also given to the risk management plans of the Aero-Space Technology programs, including the X-33, X-34, and X-38. Overall, the Panel concluded that safety is well served for the present. The picture is not as clear for the future. Cutbacks have limited the depth of talent available. In many cases, technical specialties are "one deep." The extended hiring freeze has resulted in an older workforce that will inevitably suffer significant departures from retirements in the near future. The resulting "brain drain" could represent a future safety risk unless appropriate succession planning is started expeditiously. This and other topics are covered in the section addressing workforce. In the case of the Space Shuttle, beneficial and mandatory safety and operational upgrades are being delayed because of a lack of sufficient present funding. Likewise, the ISS has little flexibility to begin long lead-time items for upgrades or contingency planning.

    Background: Despite the increasing interest in medical education in the German-speaking countries, there is currently no information available on the challenges which medical educators face. To address this problem, we carried out a web-based survey among the members of the Association for Medical Education (Gesellschaft für medizinische Ausbildung, GMA). Methods: A comprehensive survey was carried out on the need for further qualifications, expertise and the general conditions of medical educators in Germany. As part of this study, the educators were asked to list the three main challenges which they faced and which required urgent improvement. The results were analysed by means of qualitative content analysis. Results: The questionnaire was completed by 147 of the 373 members on the GMA mailing list (response rate: 39%). The educators named a total of 346 challenges and emphasised the following areas: limited academic recognition for engagement in teaching (53.5% of educators), insufficient institutional (31.5%) and financial support (28.4%), a curriculum in need of reform (22.8%), insufficient time for teaching assignments (18,9%), inadequate teacher competence in teaching methods (18.1%), restricted faculty development programmes (18.1%), limited networking within the institution (11.0%), lack of teaching staff (10.2%), varying preconditions of students (8.7%), insufficient recognition and promotion of medical educational research (5.5%), extensive assessment requirements (4.7%), and the lack of role models within medical education (3.2%). Conclusion: The medical educators found the biggest challenges which they faced to be limited academic recognition and insufficient institutional and financial support. Consequently, improvements should be implemented to address these issues. PMID:24062818

    Objective This study aimed to examine whether educational stressors and relational stressors are associated with burnout in medical students and to test social support as a moderator between stressors and burnout. Methods A total of 263 medical students attending Gyeongsang National University composed the study sample. A standardized questionnaire was used to investigate educational and relational stressors, three dimensions of burnout, and social support of medical students. Results The findings showed that overall burnout is very high among Korean medical students, with 9.9% totally burned out. Educational and relational stressors were significantly associated with the risk of burnout in medical students after controlling for socio-demographics and health behaviors. Social support moderated educational and relational stressors on personal accomplishment, but did not moderate stressors on emotional exhaustion and depersonalization. Conclusion Burnout level is substantially high among Korean medical students. Educational and relational stressors are significantly associated with burnout risk in Korean medical students. Social support had moderated educational and relational stressors on personal accomplishment. The results suggest that more social support for medical students is needed to buffer stressors on and burnout. PMID:26508955

    Introduction. Medicine is one of the most stressful fields of education because of its highly demanding professional and academic requirements. Psychological stress, anxiety, depression and sleep disturbances are highly prevalent in medical students. Methods. This cross-sectional study was undertaken at the Combined Military Hospital Lahore Medical College and the Institute of Dentistry in Lahore (CMH LMC), Pakistan. Students enrolled in all yearly courses for the Bachelor of Medicine and Bachelor of Surgery (MBBS) degree were included. The questionnaire consisted of four sections: (1) demographics (2) a table listing 34 potential stressors, (3) the 14-item Perceived Stress Scale (PSS-14), and (4) the Pittsburgh Quality of Sleep Index (PSQI). Logistic regression was run to identify associations between group of stressors, gender, year of study, student's background, stress and quality of sleep. Results. Total response rate was 93.9% (263/280 respondents returned the questionnaire). The mean (SD) PSS-14 score was 30 (6.97). Logistic regression analysis showed that cases of high-level stress were associated with year of study and academic-related stressors only. Univariate analysis identified 157 cases with high stress levels (59.7%). The mean (SD) PSQI score was 8.1 (3.12). According to PSQI score, 203/263 respondents (77%) were poor sleepers. Logistic regression showed that mean PSS-14 score was a significant predictor of PSQI score (OR 1.99, P < 0.05). Conclusion. We found a very high prevalence of academic stress and poor sleep quality among medical students. Many medical students reported using sedatives more than once a week. Academic stressors contributed significantly to stress and sleep disorders in medical students. PMID:25802809

    Objective: The evaluation of medical research performance is a key prerequisite for the systematic advancement of medical faculties, research foci, academic departments, and individual scientists’ careers. However, it is often based on vaguely defined aims and questionable methods and can thereby lead to unwanted regulatory effects. The current paper aims at defining the position of German academic medicine toward the aims, methods, and consequences of its evaluation. Methods: During the Berlin Forum of the Association of the Scientific Medical Societies in Germany (AWMF) held on 18 October 2013, international experts presented data on methods for evaluating medical research performance. Subsequent discussions among representatives of relevant scientific organizations and within three ad-hoc writing groups led to a first draft of this article. Further discussions within the AWMF Committee for Evaluation of Performance in Research and Teaching and the AWMF Executive Board resulted in the final consented version presented here. Results: The AWMF recommends modifications to the current system of evaluating medical research performance. Evaluations should follow clearly defined and communicated aims and consist of both summative and formative components. Informed peer reviews are valuable but feasible in longer time intervals only. They can be complemented by objective indicators. However, the Journal Impact Factor is not an appropriate measure for evaluating individual publications or their authors. The scientific “impact” rather requires multidimensional evaluation. Indicators of potential relevance in this context may include, e.g., normalized citation rates of scientific publications, other forms of reception by the scientific community and the public, and activities in scientific organizations, research synthesis and science communication. In addition, differentiated recommendations are made for evaluating the acquisition of third-party funds and the

    Between six percent and 35% of psychiatric patients discharge themselves from hospital against medical advice (AMA). The discharges may prevent patients from deriving the full benefit of hospitalization and may result in rapid rehospitalization. We examined sociodemographic and clinical characteristics of 195 irregular discharges from a 237 bed psychiatric hospital over a five year period and found that AMA discharges increased over the study period to a peak of 25% in 1986. There was a strong negative correlation between AMA discharge rates and the willingness of physicians to commit patients involuntarily. Multiple discriminant analysis revealed a set of nine variables that accurately classified 78% of cases into regular or irregular discharge categories. Further analysis revealed that there are two distinct subgroups of patients who discharge themselves AMA: those who repeatedly left the hospital AMA in a regular "revolving back door" pattern and those who left AMA only once. The repeat group exceeded the one-time group in terms of prior admissions, appearances before review boards, and percentage of Natives. The repeat group also spent twice as long in hospital, and 27% were readmitted within one-week of the index AMA discharge. Less than three percent of the one-time AMA group was readmitted within a week. These results were cross-validated on a new sample of irregular discharges and matched controls. PMID:8518982

  9. Aerospace Safety Advisory Panel

    NASA Technical Reports Server (NTRS)

    2002-01-01

    This Annual Report of the Aerospace Safety Advisory Panel (ASAP) presents results of activities during calendar year 2001. The year was marked by significant achievements in the Space Shuttle and International Space Station (ISS) programs and encouraging accomplishments by the Aerospace Technology Enterprise. Unfortunately, there were also disquieting mishaps with the X-43, a LearJet, and a wind tunnel. Each mishap was analyzed in an orderly process to ascertain causes and derive lessons learned. Both these accomplishments and the responses to the mishaps led the Panel to conclude that safety and risk management is currently being well served within NASA. NASA's operations evidence high levels of safety consciousness and sincere efforts to place safety foremost. Nevertheless, the Panel's safety concerns have never been greater. This dichotomy has arisen because the focus of most NASA programs has been directed toward program survival rather than effective life cycle planning. Last year's Annual Report focused on the need for NASA to adopt a realistically long planning horizon for the aging Space Shuttle so that safety would not erode. NASA's response to the report concurred with this finding. Nevertheless, there has been a greater emphasis on current operations to the apparent detriment of long-term planning. Budget cutbacks and shifts in priorities have severely limited the resources available to the Space Shuttle and ISS for application to risk-reduction and life-extension efforts. As a result, funds originally intended for long-term safety-related activities have been used for operations. Thus, while safety continues to be well served at present, the basis for future safety has eroded. Section II of this report develops this theme in more detail and presents several important, overarching findings and recommendations that apply to many if not all of NASA's programs. Section III of the report presents other significant findings, recommendations and supporting

    1988-01-01

    Presented is an overview of heat transfer related research in support of aerospace propulsion, particularly as seen from the perspective of the NASA Lewis Research Center. Aerospace propulsion is defined to cover the full spectrum from conventional aircraft power plants through the Aerospace Plane to space propulsion. The conventional subsonic/supersonic aircraft arena, whether commercial or military, relies on the turbine engine. A key characteristic of turbine engines is that they involve fundamentally unsteady flows which must be properly treated. Space propulsion is characterized by very demanding performance requirements which frequently push systems to their limits and demand tailored designs. The hypersonic flight propulsion systems are subject to severe heat loads and the engine and airframe are truly one entity. The impact of the special demands of each of these aerospace propulsion systems on heat transfer is explored.

    The main sequelae of endometriosis are represented by infertility and chronic pelvic pain. Chronic pelvic pain causes disability and distress with a very high economic impact. In the last decades, an impressive amount of pharmacological agents have been tested for the treatment of endometriosis-associated pelvic pain. However, only a few of these have been introduced into clinical practice. Following the results of the controlled studies available, to date, the first-line treatment for endometriosis associated pain is still represented by oral contraceptives used continuously. Progestins represent an acceptable alternative. In women with rectovaginal lesions or colorectal endometriosis, norethisterone acetate at low dosage should be preferred. GnRH analogues may be used as second-line treatment, but significant side effects should be taken into account. Nonsteroidal anti-inflammatory drugs are widely used, but there is inconclusive evidence for their efficacy in relieving endometriosis-associated pelvic pain. Other agents such as GnRH antagonist, aromatase inhibitors, immunomodulators, selective progesterone receptor modulators, and histone deacetylase inhibitors seem to be very promising, but there is not enough evidence to support their introduction into routine clinical practice. Some other agents, such as peroxisome proliferator activated receptors-γ ligands, antiangiogenic agents, and melatonin have been proven to be efficacious in animal studies, but they have not yet been tested in clinical studies.

    In the era of targeted therapies and combined modalities of treatment, scientific research plays a role of paramount importance in improving knowledge of cancer treatment. The aim of this survey was to review the scientific activity of medical oncology units in Sicily and to analyze their needs and possible pitfalls in order to improve future scientific cooperation.The regional section of the Italian Association of medical Oncology (AIOM) approved this survey in November, 2007. A systematic review of scientific activity produced by medical oncology units in Sicily during the last 5 years has been reviewed. papers dealing with solid tumors reported in the pubmed web site have been included in the analysis. Data were reported as absolute number of published papers and impact factor per medical oncology unit and also as a ratio between global impact factor and the number of personnel working in each single unit to analyze scientific production according to the workforce of each institution.We identified a total of 283 papers reported in pubmed between 2004 and march, 2009. The mean number of publications/unit was 10.9 with a range of 0-50. The mean number of publications/year was 11.7 with a range of 0.2-10. The 15 units included in the impact factor evaluation published 252 papers with a total impact factor of 1014.6 points in 5 years with a mean of 63.4 points per institution and a mean of 4.02 points/paper. However only four medical oncology units reported a cumulative 5-year impact factor >100 points.This survey has shown that a minority of medical oncology units in Sicily is constantly involved in clinical research although at different levels of activity. Overall the percentage of patients enrolled in clinical trials is very low. The main reasons for lack of participation in clinical trials include insufficient medical personnel, the absence of a specifically dedicated research unit inside the medical oncology structures and in some cases lack of research

    The mechanisms of stress-related immune alterations have not been fully elucidated. Cell-mediated immune responses as well as antibody and certain cytokines are reported as being suppressed during times of high stress. However, the role of suppression vs dysregulation has not been established in human stress models. The effect of exam stress on regulatory cytokines in 16 healthy medical students was assessed by measuring type-1 (IFN-gamma) and type-2 (IL-10) cytokines from 72-h PHA/PMA-stimulated PBMC 4 weeks before and 48 h after exams. Results demonstrated decreased IFN-gamma accompanied by increased IL-10 during exam stress that resulted in a decreased IFN-gamma:IL-10 ratio. There was a significant correlation between the cytokine response to PHA/PMA and number and subjective adjustment to daily hassles. Additionally, students who reported greater levels of loneliness also reported greater numbers of and poorer subjective adjustment to hassles. The differences were consistent in both males and females but did not correlate with AM cortisol levels. Additionally, when individuals were grouped into high vs low preexam hassle levels, the type-1/type-2 shift in the IFN-gamma:IL-10 ratio occurred in the low hassles group only. These data suggest that psychologically stressful situations shift type-1/type-2 cytokine balance toward type-2 and result in an immune dysregulation rather than overall immunosuppression. This may partially explain the increased incidence of type-2-mediated conditions such as increased viral infections, latent viral expression, allergic/asthmatic reactions, and autoimmunity reported during periods of high stress.

  20. Aerospace safety advisory panel

    1995-01-01

    The Aerospace Safety Advisory Panel (ASAP) monitored NASA's activities and provided feedback to the NASA Administrator, other NASA officials and Congress throughout the year. Particular attention was paid to the Space Shuttle, its launch processing and planned and potential safety improvements. The Panel monitored Space Shuttle processing at the Kennedy Space Center (KSC) and will continue to follow it as personnel reductions are implemented. There is particular concern that upgrades in hardware, software, and operations with the potential for significant risk reduction not be overlooked due to the extraordinary budget pressures facing the agency. The authorization of all of the Space Shuttle Main Engine (SSME) Block II components portends future Space Shuttle operations at lower risk levels and with greater margins for handling unplanned ascent events. Throughout the year, the Panel attempted to monitor the safety activities related to the Russian involvement in both space and aeronautics programs. This proved difficult as the working relationships between NASA and the Russians were still being defined as the year unfolded. NASA's concern for the unique safety problems inherent in a multi-national endeavor appears appropriate. Actions are underway or contemplated which should be capable of identifying and rectifying problem areas. The balance of this report presents 'Findings and Recommendations' (Section 2), 'Information in Support of Findings and Recommendations' (Section 3) and Appendices describing Panel membership, the NASA response to the March 1994 ASAP report, and a chronology of the panel's activities during the reporting period (Section 4).

The main focus of the Aerospace Safety Advisory Panel (ASAP) during 1988 has been monitoring and advising NASA and its contractors on the Space Transportation System (STS) recovery program. NASA efforts have restored the flight program with a much better management organization, safety and quality assurance organizations, and management communication system. The NASA National Space Transportation System (NSTS) organization in conjunction with its prime contractors should be encouraged to continue development and incorporation of appropriate design and operational improvements which will further reduce risk. The data from each Shuttle flight should be used to determine if affordable design and/or operational improvements could further increase safety. The review of Critical Items (CILs), Failure Mode Effects and Analyses (FMEAs) and Hazard Analyses (HAs) after the Challenger accident has given the program a massive data base with which to establish a formal program with prioritized changes.

    Due to the great prevalence of persistent and recurrent implanted device associated-infections novel and alternative therapeutic approaches are intensely investigated. For reducing complications and antibiotic resistance development, one major strategy is using natural or synthetic modulators for targeting microbial molecular pathways which are not related with cell multiplication and death, as Quorum Sensing, virulence and biofilm formation. The purpose of this review paper is to discuss the most recent in vitro approaches, investigating the efficiency of some novel antimicrobial products and the nano-technologic progress performed in order to increase their effect and stability.

    Background Although there are several different general diabetes self-efficacy scales, there is a need to develop a self-efficacy scale that providers can use to assess patient’s self-efficacy regarding medication use. The purpose of this study was to: 1) develop a new diabetes medication self-efficacy scale and 2) examine how diabetes medication self-efficacy is associated with patient-reported problems in using diabetes medications and self-reported adherence. Patients and methods Adult English-speaking patients with type 2 diabetes were recruited from a family medicine clinic and a pharmacy in Eastern North Carolina, USA. The patients were eligible if they reported being nonadherent to their diabetes medicines on a visual analog scale. Multivariable regression was used to examine the relationship between self-efficacy and the number of reported diabetes medication problems and adherence. Results The diabetes medication self-efficacy scale had strong reliability (Cronbach’s alpha =0.86). Among a sample (N=51) of mostly African-American female patients, diabetes medication problems were common (6.1±3.1) and a greater number of diabetes medications were associated with lower medication adherence (odds ratio: 0.35; 95% confidence interval: 0.13, 0.89). Higher medication self-efficacy was significantly related to medication adherence (odds ratio: 1.17; 95% confidence interval: 1.05, 1.30) and inversely related to the number of self-reported medication problems (β=−0.13; P=0.006). Conclusion Higher diabetes medication self-efficacy was associated with fewer patient-reported medication problems and better medication adherence. Assessing medication-specific self-efficacy may help to identify medication-related problems that providers can help the patients address, potentially improving adherence and patient outcomes.

    Oral actinomycosis is not a common disease, but it can cause massive destruction. This article reports a case of implant failure associated with actinomycosis. A 55-year-old Caucasian male patient had tooth #20 extracted years ago and an implant placed 3 years ago. The #20 implant area developed an abscess about 1½ years after implant placement. Radiographic findings revealed a large radiolucency on the mesial aspect of the #20 implant. The implant was surgically removed and the lesion thoroughly debrided. The patient experienced severe pain when the apical soft tissue was curreted following implant removal. A periapical radiograph revealed that the lesion approached the mental foramen. A short course of antibiotics was prescribed. Histological observation found sulfur granules, which were found to be actinomycotic colonies. Peri-implant actinomycosis was diagnosed. No recurrence had occurred at the 1-year follow-up. PMID:21767210

    Many studies have reported that the prevalence of psychological distress among medical students during medical training was high. However, there are very few studies exploring on the psychological health of prospective medical students. This study aimed to determine the prevalence and associated factors for stress, anxiety and depression symptoms among the prospective medical students. A cross-sectional study was done on two cohorts of applicants to a public medical school. A total of 839 applicants were invited to participate in the study. The 21-item Depression Anxiety Stress Scale was administered to the applicants after they completed interviews. A total of 743 (92.2%) applicants took part in the study. The prevalence of moderate to extremely severe level of stress, anxiety and depression were 3.6%, 54.5% and 1.9%, respectively. Stress was significantly associated with extra-curricular activity (p<0.001) and race (p<0.001). Anxiety was associated with extra-curricular activity (p<0.001), race (p<0.001), mother education level (p=0.002) and CGPA group (p=0.034). Depression was associated with academic performance in class (p<0.001) and race (p=0.004). Prevalence of stress and depression among entering medical students was low; however prevalence of anxiety was high which could be due to worry about the interviews to enter medical course. The associated factors of psychological distress among prospective medical students were related to academic, non-academic, parent education and cultural backgrounds. PMID:23466109

    This annual report is based on the activities of the Aerospace Safety Advisory Panel in calendar year 2000. During this year, the construction of the International Space Station (ISS) moved into high gear. The launch of the Russian Service Module was followed by three Space Shuttle construction and logistics flights and the deployment of the Expedition One crew. Continuous habitation of the ISS has begun. To date, both the ISS and Space Shuttle programs have met or exceeded most of their flight objectives. In spite of the intensity of these efforts, it is clear that safety was always placed ahead of cost and schedule. This safety consciousness permitted the Panel to devote more of its efforts to examining the long-term picture. With ISS construction accelerating, demands on the Space Shuttle will increase. While Russian Soyuz and Progress spacecraft will make some flights, the Space Shuttle remains the primary vehicle to sustain the ISS and all other U.S. activities that require humans in space. Development of a next generation, human-rated vehicle has slowed due to a variety of technological problems and the absence of an approach that can accomplish the task significantly better than the Space Shuttle. Moreover, even if a viable design were currently available, the realities of funding and development cycles suggest that it would take many years to bring it to fruition. Thus, it is inescapable that for the foreseeable future the Space Shuttle will be the only human-rated vehicle available to the U.S. space program for support of the ISS and other missions requiring humans. Use of the Space Shuttle will extend well beyond current planning, and is likely to continue for the life of the ISS.

    This research examined provider and hospital factors associated with patients' perceptions of how often explanations of new medications were "always" given to them, using Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores. HCAHPS results were obtained for October 2012 to September 2013, from 3,420 hospitals and combined with a Magnet-designated hospital listing. Multiple regression examined correlates of new medication communication, including health care provider factors (perceptions of nurse and physician communication) and health care system factors (magnet designation, hospital ownership, hospital type, availability of emergency services, and survey numbers). Nurse and physician communication was strongly associated with new medication communication (r = .819, p < .001; r = .722, p < .001, respectively). Multivariable correlates included nurse communication (p < .001), physician communication (p < .001), hospital ownership, availability of emergency services, and survey numbers. There was a significant relationship between patients' perceptions of nurse and physician communication and the explanations they had received about their new medications during hospitalization.

    A complex disaster, the Great East Japan Earthquake of March 11, 2011, consisted of a large-scale earthquake, tsunami, and nuclear accident, resulting in more than 15 000 fatalities, injuries, and missing persons and damage over a 500-km area. The entire Japanese public was profoundly affected by "3/11." The risk of radiation exposure initially delayed the medical response, prolonging the recovery efforts. Japan's representative medical organization, the Japan Medical Association (JMA), began dispatching Japan Medical Association Teams (JMATs) to affected areas beginning March 15, 2011. About 1400 JMATs comprising nearly 5500 health workers were launched. The JMA coordinated JMAT operations and cooperated in conducting postmortem examination, transporting large quantities of medical supplies, and establishing a multiorganizational council to provide health assistance to disaster survivors. Importantly, these response efforts contributed to the complete recovery of the health care system in affected areas within 3 months, and by July 15, 2011, JMATs were withdrawn. Subsequently, JMATs II have been providing long-term continuing medical support to disaster-affected areas. However, Japan is at great risk for future natural disasters because of its Pacific Rim location. Also, its rapidly aging population, uneven distribution of and shortage of medical resources in regional communities, and an overburdened public health insurance system highlight the need for a highly prepared and effective disaster response system.

    Physical inactivity is a major risk factor for chronic diseases and premature death. The increased health risks associated with physical inactivity may also generate a heavier economic burden to society. We estimated the direct medical costs attributable to physical inactivity among adults using data from the 2002-2010 Korean National Health Insurance Service-National Sample Cohort. A total of 68,556 adults whose reported physical activity status did not change during the study period was included for this study. Propensity scores for inactive adults were used to match 23,645 inactive groups with 23,645 active groups who had similar propensity scores. We compared medical expenditures between the two groups using generalized linear models with a gamma distribution and a log link. Direct medical costs were based on the reimbursement records of all medical facilities from 2005 to 2010. The average total medical costs for inactive individuals were $1110.5, which was estimated to be 11.7% higher than the costs for physically active individuals. With respect to specific diseases, the medical costs of inactive people were significantly higher than those of active people, accounting for approximately 8.7% to 25.3% of the excess burden. Physical inactivity is associated with considerable medical care expenditures per capita among Korean adults. PMID:26797622

    Health care associated infections (HCAIs) add incrementally to the morbidity, mortality, and cost expected of the patient's underlying diseases alone. Approximately, about half all cases of HCAIs are associated with medical devices. As Candida medical device-associated infection is highly drug resistant and can lead to serious life-threatening complications, there is a need of continuous surveillance of these infections to initiate preventive and corrective measures. The present study was conducted at a rural tertiary care hospital of India with an aim to evaluate the rate of medical device-associated Candida infections. Three commonly encountered medical device-associated infections (MDAI), catheter-associated urinary tract infection (CA-UTI), intravascular catheter-related blood stream infections (CR-BSI), and ventilator-associated pneumonia (VAP), were targeted. The overall rate of MDAI in our hospital was 2.1 per 1000 device days. The rate of Candida related CA-UTI and CR-BSI was noted as 1.0 and 0.3, respectively. Untiring efforts taken by team members of Hospital Acquired Infection Control Committee along with maintenance of meticulous hygiene of the hospital and wards may explain the low MDAI rates in our institute. The present surveillance helped us for systematic generation of institutional data regarding MDAI with special reference to role of Candida spp. PMID:26904115

    2002-01-01

    This report presents the results of the Aerospace Safety Advisory Panel (ASAP) activities during 2002. The format of the report has been modified to capture a long-term perspective. Section II is new and highlights the Panel's view of NASA's safety progress during the year. Section III contains the pivotal safety issues facing NASA in the coming year. Section IV includes the program area findings and recommendations. The Panel has been asked by the Administrator to perform several special studies this year, and the resulting white papers appear in Appendix C. The year has been filled with significant achievements for NASA in both successful Space Shuttle operations and International Space Station (ISS) construction. Throughout the year, safety has been first and foremost in spite of many changes throughout the Agency. The relocation of the Orbiter Major Modifications (OMMs) from California to Kennedy Space Center (KSC) appears very successful. The transition of responsibilities for program management of the Space Shuttle and ISS programs from Johnson Space Center (JSC) to NASA Headquarters went smoothly. The decision to extend the life of the Space Shuttle as the primary NASA vehicle for access to space is viewed by the Panel as a prudent one. With the appropriate investments in safety improvements, in maintenance, in preserving appropriate inventories of spare parts, and in infrastructure, the Space Shuttle can provide safe and reliable support for the ISS for the foreseeable future. Indications of an aging Space Shuttle fleet occurred on more than one occasion this year. Several flaws went undetected in the early prelaunch tests and inspections. In all but one case, the problems were found prior to launch. These incidents were all handled properly and with safety as the guiding principle. Indeed, launches were postponed until the problems were fully understood and mitigating action could be taken. These incidents do, however, indicate the need to analyze the

    During 1997, the Aerospace Safety Advisory Panel (ASAP) continued its safety reviews of NASA's human space flight and aeronautics programs. Efforts were focused on those areas that the Panel believed held the greatest potential to impact safety. Continuing safe Space Shuttle operations and progress in the manufacture and testing of primary components for the International Space Station (ISS) were noteworthy. The Panel has continued to monitor the safety implications of the transition of Space Shuttle operations to the United Space Alliance (USA). One area being watched closely relates to the staffing levels and skill mix in both NASA and USA. Therefore, a section of this report is devoted to personnel and other related issues that are a result of this change in NASA's way of doing business for the Space Shuttle. Attention will continue to be paid to this important topic in subsequent reports. Even though the Panel's activities for 1997 were extensive, fewer specific recommendations were formulated than has been the case in recent years. This is indicative of the current generally good state of safety of NASA programs. The Panel does, however, have several longer term concerns that have yet to develop to the level of a specific recommendation. These are covered in the introductory material for each topic area in Section 11. In another departure from past submissions, this report does not contain individual findings and recommendations for the aeronautics programs. While the Panel devoted its usual efforts to examining NASA's aeronautic centers and programs, no specific recommendations were identified for inclusion in this report. In lieu of recommendations, a summary of the Panel's observations of NASA's safety efforts in aeronautics and future Panel areas of emphasis is provided. With profound sadness the Panel notes the passing of our Chairman, Paul M. Johnstone, on December 17, 1997, and our Staff Assistant, Ms. Patricia M. Harman, on October 5, 1997. Other

    This study aims to assess the prevalence of stress and burnout among preclinical medical students in a private university in Beirut, Lebanon, and evaluate the association between extracurricular involvement and stress and burnout relief in preclinical medical students. A cross-sectional survey was conducted on a random sample of 165 preclinical medical students. Distress level was measured using the 12-item General Health Questionnaire (GHQ-12) while that of burnout was measured through the Maslach Burnout Inventory-Student Survey (MBI-SS). The MBI-SS assesses three interrelated dimensions: emotional exhaustion, cynicism, and academic efficacy. Extracurricular activities were divided into four categories: physical exercise, music, reading, and social activities. All selected participants responded. A substantial proportion of preclinical medical students suffered from stress (62%) and burnout (75%). Bivariate and multivariate regression analyses revealed that being a female or a 1st year medical student correlated with higher stress and burnout. Music-related activities were correlated with lower burnout. Social activities or living with parents were associated with lower academic efficacy. The high stress and burnout levels call for action. Addressing the studying conditions and attending to the psychological wellbeing of preclinical medical students are recommendations made in the study. PMID:26644345

    The present study was designed to analyze association between problematic internet use and use of ego defense mechanisms in medical students. This cross-sectional study was undertaken at CMH Lahore Medical College (CMH LMC) in Lahore, Pakistan from 1st March, 2015 to 30th May, 2015. 522 medical and dental students were included in the study. The questionnaire consisted of three sections: a) demographic characteristics of respondent b) the Defense Style Questionnaire-40 (DSQ-40) and c) the Internet Addiction Test (IAT). All data were analyzed in SPSS v20. Chi square, Independent sample t test and One Way ANOVA were run to analyze association of different variables with scores on IAT. Multiple regression analysis was used to delineate ego defenses as predictors of problematic internet use. A total of 32 (6.1%) students reported severe problems with internet usage. Males had higher scores on IAT i.e had more problematic use of internet. Scores on internet addiction test (IAT) were negatively associated with sublimation and positively associated with projection, denial, autistic fantasy, passive aggression and displacement. There was a high prevalence of problematic use of internet among medical and dental students. It had significant associations with several defense mechanisms. PMID:27504797

    Introduction: Burnout is a widely known phenomenon. It is defined as a state of prolonged physical and psychological exhaustion and is experienced virtually by every medical student due to the highly demanding nature of medical education. This study probes into the prevalence and psychosocial determinants of burnout in Pakistani medical students. Methods: A descriptive, cross-sectional study design and convenience (non-probability) sampling technique were employed in undergraduate medical students from years 1-5. A total of 777 medical students from two medical colleges were included in the study from May-August, 2014. An English version of the Copenhagen Burnout Inventory (CBI) and a series of demographic questions, intermixed with questions from other topics, were included in the questionnaire. Data was analysed by using SPSS ver.21. Results: The majority of students were females and enrolled in the third year of MBBS. Of the medical students involved, 30.6% were found to have high/very high levels of burnout (Kristenson’s burnout scoring). Although 38.7% of students said that they did not feel burned out after reading the definition of burnout given in the questionnaire, 35.9% out of these students actually had high levels of burnout according to CBI. According to the multiple regression analysis, burnout in medical students was significantly associated with age, gender, doctor parents, no help or no supportive resources (e.g., from colleagues), lack of time off, lack of belief in what you do, fear of big consequences of failure, family responsibilities, and uncertain future. Perception of teachers lacking leadership skills and doing too much study with little balance was associated with low burnout scores. Conclusion: There is a high prevalence of burnout in Pakistani medical students. The present study identifies several factors associated with burnout in Pakistani medical students. Although these factors are a part of daily life of medical students, their

    Objectives Nonadherence to antihypertensive medications has not been assessed in the Saudi population. The aim of this study was to address and evaluate the magnitude of nonadherence among hypertensive patients and the risk factors associated with it. Methods A cross-sectional survey was conducted on hypertensive patients who attended the general internal medicine clinics at King Abdulaziz Medical City, Riyadh, Saudi Arabia, using a questionnaire that was modified after reviewing the literature. Hypertensive patients were labeled as nonadherent if they missed their medications for a total of 7 days during the previous month. Results A total of 302 patients participated in the study, of whom 63% were females with a mean age of 64 years, and 64% were illiterate. The prevalence of nonadherence to medications among hypertensive patients was found to be 12.3%. Poor disease knowledge was reported in 80% of patients, while 66% of the patients had poor monitoring of their disease. Younger age (≤65 years), poor monitoring, and uncontrolled blood pressure (BP ≥140/90 mmHg) were the predictor factors associated with nonadherence (odds ratio [OR] =2.04, P=0.025; OR=2.39, P=0.004; and OR=2.86, P=0.003, respectively). Conclusion Nonadherence to antihypertensive medications is lower than that previously reported in the literature. Younger age, uncontrolled BP, and poor monitoring are the main risk factors associated with nonadherence. PMID:27536073

    Purpose Medical student mistreatment has been recognized for decades and is known to adversely impact students both personally and professionally. Similarly, burnout has been shown to negatively impact students. This study assesses the prevalence of student mistreatment across multiple medical schools and characterizes the association between mistreatment and burnout. Method In 2011, the authors surveyed a nationally representative sample of third-year medical students. Students reported the frequency of mistreatment by attending faculty and residents since the beginning of their clinical rotations. Burnout was measured using a validated two-item version of the Maslach Burnout Inventory. Results Of 919 eligible students from 24 different medical schools, 564 (61%) completed the survey. The majority reported at least one incident of mistreatment by faculty (64% [361/562]) and by residents (75.5% [426/562]). Notable minorities experienced recurrent mistreatment, defined as mistreatment categorized as “several” or “numerous” times by student self-report (10.7% [59/562] by faculty and 12.6% [71/562] by residents). Recurrent mistreatment was associated with high burnout (57.4% vs. 31.5%; p<0.01 for recurrent mistreatment by faculty; 49.1% vs. 32.1%; p<0.01 for recurrent mistreatment by residents). Conclusions Medical student mistreatment remains prevalent. Recurrent mistreatment by faculty and residents is associated with medical student burnout. Although further investigation is needed to assess causality, these data provide additional impetus for medical schools to address student mistreatment to mitigate its adverse consequences on their personal and professional well-being.

    Background Ulcerative colitis (UC) can be treated with surgery or medications. Patients often must choose between long-term immunosuppressive therapy or total colectomy. It is uncertain if there is a mortality benefit to one of these treatment approaches. Objective To determine whether patients with advanced UC treated with elective colectomy have an improved survival compared to patients treated with medical therapy. Design Retrospective matched cohort study Setting 50-state Medicaid and beneficiaries (2000–2005), Medicare-beneficiaries (2006–2011) and dual-eligible individuals (2000–2011) Patients 830 UC patients pursuing elective colectomy surgery and 7,541 matched UC patients pursuing medical therapy. Measurements The primary outcome was time to death. Cox proportional hazard models were used to compare the survival of advanced UC patients treated with elective colectomy or medical therapy. The models controlled for significant comorbidities through matched and adjusted analysis. Results The mortality rates associated with elective surgery and medical therapy were 34 and 54 per 1,000 person-years, respectively. Elective colectomy was associated with improved survival compared to pursuing chronic medical therapy (adjusted HR 0.67, 95% CI 0.52–0.87) although not all results remained statistically significant in the sensitivity analyses. Post-hoc analysis by age group showed improved survival with surgery in patients 50 years and older with advanced UC (HR 0.60, 95% CI 0.45–0.79, age by treatment interaction p=0.032). Limitation Retrospective non-randomized analysis can be subject to residual confounding. The source cohort was derived from different databases across the study period. Sensitivity and secondary analyses had reduced statistical power. Conclusion Elective colectomy surgery appeared to be associated with an improved survival rate relative to medical therapy among patients 50 years and older with advanced UC. PMID:26168366

    Objective Chronic widespread pain and chronic fatigue share common associated factors but these associations may be explained by the presence of concurrent depression and anxiety. Methods We mailed questionnaires to a randomly selected sample of people in the UK to identify participants with chronic widespread pain (ACR 1990 definition) and those with chronic fatigue. The questionnaire assessed sociodemographic factors, health status, healthcare use, childhood factors, adult attachment, and psychological stress including anxiety and depression. To identify persons with unexplained chronic widespread pain or unexplained chronic fatigue; we examined participant's medical records to exclude medical illness that might cause these symptoms. Results Of 1443 participants (58.0% response rate) medical records of 990 were examined. 9.4% (N = 93) had unexplained chronic widespread pain and 12.6% (N = 125) had unexplained chronic fatigue. Marital status, childhood psychological abuse, recent threatening experiences and other somatic symptoms were commonly associated with both widespread pain and fatigue. No common effect was found for few years of education and current medical illnesses (more strongly associated with chronic widespread pain) or recent illness in a close relative, neuroticism, depression and anxiety scores (more strongly associated with chronic fatigue). Putative associated factors with a common effect were associated with unexplained chronic widespread pain or unexplained chronic fatigue only when there was concurrent anxiety and/or depression. Discussion This study suggests that the associated factors for chronic widespread pain and chronic fatigue need to be studied in conjunction with concurrent depression/anxiety. Clinicians should be aware of the importance of concurrent anxiety or depression. PMID:26652592

    While the cost and speed of generating genomic data have come down dramatically in recent years, the slow pace of collecting medical data for large cohorts continues to hamper genetic research. Here we evaluate a novel online framework for obtaining large amounts of medical information from a recontactable cohort by assessing our ability to replicate genetic associations using these data. Using web-based questionnaires, we gathered self-reported data on 50 medical phenotypes from a generally unselected cohort of over 20,000 genotyped individuals. Of a list of genetic associations curated by NHGRI, we successfully replicated about 75% of the associations that we expected to (based on the number of cases in our cohort and reported odds ratios, and excluding a set of associations with contradictory published evidence). Altogether we replicated over 180 previously reported associations, including many for type 2 diabetes, prostate cancer, cholesterol levels, and multiple sclerosis. We found significant variation across categories of conditions in the percentage of expected associations that we were able to replicate, which may reflect systematic inflation of the effects in some initial reports, or differences across diseases in the likelihood of misdiagnosis or misreport. We also demonstrated that we could improve replication success by taking advantage of our recontactable cohort, offering more in-depth questions to refine self-reported diagnoses. Our data suggest that online collection of self-reported data from a recontactable cohort may be a viable method for both broad and deep phenotyping in large populations. PMID:21858135

    1994-01-01

    Magnetic bearings have traditionally been considered for use in aerospace applications only where performance advantages have been the primary, if not only, consideration. Conventional wisdom has been that magnetic bearings have certain performance advantages which must be traded off against increased weight, volume, electric power consumption, and system complexity. These perceptions have hampered the use of magnetic bearings in many aerospace applications because weight, volume, and power are almost always primary considerations. This paper will review progress on several active aerospace magnetic bearings programs at SatCon Technology Corporation. The magnetic bearing programs at SatCon cover a broad spectrum of applications including: a magnetically-suspended spacecraft integrated power and attitude control system (IPACS), a magnetically-suspended momentum wheel, magnetic bearings for the gas generator rotor of a turboshaft engine, a vibration-attenuating magnetic bearing system for an airborne telescope, and magnetic bearings for the compressor of a space-rated heat pump system. The emphasis of these programs is to develop magnetic bearing technologies to the point where magnetic bearings can be truly useful, reliable, and well tested components for the aerospace community.

    Objective Rape is associated with Posttraumatic Stress Disorder and related comorbidities. Most victims do not obtain treatment for these conditions. Acute care medical settings are well-positioned to link patients to services; however, difficulty engaging victims and low attendance at provided follow-up appointments is well documented. Identifying factors associated with follow-up can inform engagement and linkage strategies. Method Administrative, patient self-report, and provider observational data from Harborview Medical Center were combined for the analysis. Using logistic regression, we examined factors associated with follow-up health service utilization after seeking services for rape in the emergency department. Results Of the 521 diverse female (n=476) and male (n=45) rape victims, 28% attended the recommended medical/counseling follow-up appointment. In the final (adjusted) logistic regression model, having a developmental or other disability (OR=0.40, 95% CI=0.21-0.77), having a current mental illness (OR=0.25, 95% CI=0.13-0.49), and being assaulted in public (OR=0.50, 95% CI=0.28-0.87) were uniquely associated with reduced odds of attending the follow-up. Having a prior mental health condition (OR= 3.02 95% CI=1.86-4.91), a completed SANE examination (OR=2.97, 95% CI=1.84-4.81), and social support available to help cope with the assault (OR=3.54, 95% CI=1.76-7.11) were associated with an increased odds of attending the follow-up. Conclusions Findings point to relevant characteristics ascertained at the acute care medical visit for rape that may be used to identify victims less likely to obtain posttraumatic medical and mental health services. Efforts to improve service linkage among these patients is warranted and may require alternative models to engage these patients to support posttraumatic recovery. PMID:26168030

    Objectives To identify the factors associated with medical students’ clinical reasoning (CR) use and evidence-based medicine (EBM) use in the clinical setting. Methods Our cross-sectional study surveyed 44 final-year medical students at an emerging academic medical center in Singapore. We queried the students’ EBM and CR value and experiences in the classroom and clinical settings. We compared this to their perceptions of supervisors’ value and experiences using t-tests. We developed measures of teaching culture and practice culture by combining relevant questions into summary scores. Multivariate linear regression models were applied to identify factors associated with the students’ CR and EBM clinical use. Results Eighty-nine percent of students responded (n=39). Students reported valuing CR (p=0.03) and EBM (p=0.001) more than their supervisors, but practiced these skills similarly (p=0.83; p=0.82). Clinical practice culture and classroom CR experience were independently associated with students’ CR clinical use (p=0.05; p=0.04), and classroom EBM experience was independently associated with students’ EBM clinical use (p=0.03). Clinical teaching culture was not associated with students’ CR and EBM clinical use. Conclusions Our study found that medical students’ classroom experience and the clinical practice culture influenced their CR and EBM use. The clinical teaching culture did not. These findings suggest that in order to increase student CR and EBM use, in addition to providing classroom experience, medical educators may need to change the hospital culture by encouraging supervisors to use these skills in their clinical practice.

    Background: Black women have the highest prevalence of hypertension in the world. Reasons for this disparity are poorly understood. The historical legacy of medical maltreatment of Blacks in the U.S. provides some insight into distrust in the medical profession, refusal of treatment, and poor adherence to treatment regimens. Methods: Black women (N = 80) who were prescribed antihypertensive medications were recruited from urban communities in North Carolina. Study participants completed the Trust in Physician and Hill-Bone Compliance to High Blood Pressure Therapy questionnaires. An exact discrete-event model was used to examine the relationship between trust and medication adherence. Results: Mean age of study participants was 48 ± 9.2 years. The majority of participants (67%) were actively employed and 30% had incomes at or below the federal poverty level. Increasing levels of trust in the health care provider was independently associated with greater medication adherence (PTrend = 0.015). Conclusion: Black women with hypertension who trusted their health care providers were more likely to be adherent with their prescribed antihypertensive medications than those who did not trust their health care providers. Findings suggest that trusting relationships between Black women and health care providers are important to decreasing disparate rates of hypertension. PMID:24350234

    At some point in their lives, nearly one-half of all American children will have a behavioral health condition. Many will not receive the care they need from a fragmented health delivery system. The patient-centered medical home is a promising model to improve their care; however, little evidence exists. Our study aim was to examine the association between several behavioral health indicators and having a patient-centered medical home. 91,642 children's parents or guardians completed the 2007 National Survey of Children's Health. An indicator for patient-centered medical home was included in the dataset. Descriptive statistics, bivariate tests, and multivariate regression models were used in the analyses. Children in the sample were mostly Male (52 %), White (78 %), non-Hispanic (87 %), and did not have a special health care need (80 %). 6.2 % of the sample had at least one behavioral health condition. Conditions ranged from ADHD (6 %) to Autism Spectrum Disorder (ASD) (1 %). Frequency of having a patient-centered medical home also varied for children with a behavioral health condition (49 % of children with ADHD and 33 % of children with ASD). Frequency of having a patient-centered medical home decreased with multiple behavioral health conditions. Higher severity of depression, anxiety, and conduct disorder were associated with a decreased likelihood of a patient-centered medical home. Results from our study can be used to target patient-centered medical home interventions toward children with one or more behavioral health conditions and consider that children with depression, anxiety, and conduct disorder are more vulnerable to these disparities.

    Background: Adverse drug events are a leading cause of hospitalization among older people. Up to half of all medication-related hospitalizations are potentially preventable. The objective of this study was to investigate and compare the association between medication regimen complexity and number of medications with unplanned hospitalizations over a 3-year period. Methods: Data were analyzed for 3,348 participants aged 60 years or older in Sweden. Regimen complexity was assessed using the 65-item Medication Regimen Complexity Index (MRCI) and number of medications was assessed as a continuous variable. Cox proportional hazard models were used to compute unadjusted and adjusted hazard ratios with 95% confidence intervals (CIs) for associations between regimen complexity and number of medications with unplanned hospitalizations over a 3-year period. Receiver operating characteristics curves with corresponding areas under the curve were calculated for regimen complexity and number of medications in relation to unplanned hospitalizations. The population attributable fraction of unplanned hospitalizations was calculated for MRCI and number of medications. Results: In total, 1,125 participants (33.6%) had one or more unplanned hospitalizations. Regimen complexity (hazard ratio 1.22; 95% CI 1.14–1.34) and number of medications (hazard ratio 1.07; 95% CI 1.04–1.09) were both associated with unplanned hospitalizations and had similar sensitivity and specificity (area under the curve 0.641 for regimen complexity and area under the curve 0.644 for number of medications). The population attributable fraction was 14.08% (95% CI 9.62–18.33) for MRCI and 17.61% (95% CI 12.59–22.35) for number of medications. Conclusions: There was no evidence that using a complex tool to assess regimen complexity was better at predicting unplanned hospitalization than number of medications. PMID:26707381

  15. Chemical Gas Sensors for Aerospace Applications

    Hunter, Gary W.; Liu, C. C.

    1998-01-01

    Chemical sensors often need to be specifically designed (or tailored) to operate in a given environment. It is often the case that a chemical sensor that meets the needs of one application will not function adequately in another application. The more demanding the environment and specialized the requirement, the greater the need to adapt exiting sensor technologies to meet these requirements or, as necessary, develop new sensor technologies. Aerospace (aeronautic and space) applications are particularly challenging since often these applications have specifications which have not previously been the emphasis of commercial suppliers. Further, the chemical sensing needs of aerospace applications have changed over the years to reflect the changing emphasis of society. Three chemical sensing applications of particular interest to the National Aeronautics and Space Administration (NASA) which illustrate these trends are launch vehicle leak detection, emission monitoring, and fire detection. Each of these applications reflects efforts ongoing throughout NASA. As described in NASA's "Three Pillars for Success", a document which outlines NASA's long term response to achieve the nation's priorities in aerospace transportation, agency wide objectives include: improving safety and decreasing the cost of space travel, significantly decreasing the amount of emissions produced by aeronautic engines, and improving the safety of commercial airline travel. As will be discussed below, chemical sensing in leak detection, emission monitoring, and fire detection will help enable the agency to meet these objectives. Each application has vastly different problems associated with the measurement of chemical species. Nonetheless, the development of a common base technology can address the measurement needs of a number of applications.

    Abstract The purpose of this cross-sectional study was to understand the prevalence and severity of health-related sequelae of traumatic exposure in a nonpsychiatric, outpatient sample. Self-report surveys were completed by patients seeking outpatient medical (n = 123) and dental care (n = 125) at a large, urban academic medical center. Results suggested that trauma exposure was associated with a decrease in perceptions of overall health and an increase in pain interference at work. Contrary to prediction, a history of interpersonal trauma was associated with less physical and emotional interference with social activities. A history of trauma exposure was associated with an increase in time elapsed since last medical visit. Depression and anxiety did not mediate the relationship between trauma history and medical care. Based on these results, clinical and research implications in relation to the health effects of trauma are discussed. The results suggest that routine screening for traumatic events may be important, particularly when providers have long-term relationships with patients. PMID:25929906

    Context: There is scant research on premenstrual syndrome (PMS) and its more severe counterpart, premenstrual dysphoric disorder (PMDD) in Indian females. This study aimed to evaluate symptoms of PMS in medical students and to find the association of sociodemographic variables and lifestyle factors with PMDD. Subjects and Methods: A total of 179 medical students residing in the hostel of an Indian medical college and its affiliated teaching hospital were approached, of which 100 (55.8%) returned the completed questionnaires. Data related to lifestyle factors was collected. Self-screening quiz for Diagnostic and Statistical Manual of Mental Disorders-IV-Text Revision PMDD and Shortened Premenstrual Assessment Form were used for diagnosis of PMDD and detection of symptomatology, respectively. Results: PMDD was present in 37% of the respondents. It was found at a higher rate in older and postgraduate students. PMDD was significantly associated with lifestyle factors, namely, sleep, physical activity, total tea/coffee intake, and change in tea/coffee and food intake under stress. The most common physical and psychological symptoms were body ache/joint pain and feeling depressed/blue, respectively. Conclusions: PMDD is fairly common in Indian medical students residing in hostel although cultural factors may influence symptom expression. This study suggests that PMDD is associated with lifestyle factors in young, professional, urban women. Modification in lifestyle may thus be an important approach for management of PMS/PMDD. Prospective studies with larger representative samples are needed to validate these findings. PMID:27212819

    Background. Blood pressure (BP) control is poor among hypertensives in many parts of sub-Saharan Africa. A potentially modifiable factor for control of BP is medication nonadherence (MNA); our study therefore aimed to determine factors associated with MNA among hypertensives in Ghana and Nigeria. Methodology. We conducted a multicenter cross-sectional study. Patients were recruited from Korle-Bu Hospital (n = 120), Ghana; and University of Port Harcourt Teaching Hospital, (n = 73) Apapa General Hospital Lagos (n = 79) and University College Hospital Ibadan (n = 85), Nigeria. Results. 357 hypertensive patients (42.6% males) participated. MNA was found in 66.7%. Adherence showed correlation with depression (r = -0.208, P < 0.001), concern about medications (r = -0.0347, P = 0.002), and knowledge of hypertension (r = 0.14, P = 0.006). MNA was associated with formal education (P = 0.001) and use of herbal preparation (P = 0.014). MNA was found in 61.7% of uninsured participants versus 73.1% of insured participants (P = 0.032). Poor BP control was observed in 69.7% and there was significant association between MNA and poor BP control (P = 0.006). Conclusion. MNA is high among hypertensives in Ghana and Nigeria and is associated with depression, concern about hypertensive medications, formal education, and use of herbal preparations. The negative association between health insurance and MNA suggests interplay of other factors and needs further investigation. PMID:26509081

    Aims/hypothesis Hyperglycaemia and dyslipidaemia are common metabolic abnormalities in adults with type 1 diabetes and both increase cardiovascular disease (CVD) risk. The hypothesis of this study was that change in HbA1c over 6 years would be associated with change in fasting lipids in adults with type 1 diabetes. Methods The Coronary Artery Calcification in Type 1 Diabetes (CACTI) study examined 652 patients with type 1 diabetes (54% female); 559 and 543 had follow-up visits at 3 and 6 years. Baseline age (mean ± SD) was 37±9 years, diabetes duration 23±9 years, and HbA1c 8.0±1.3%. Use of dyslipidaemia medication was 17%, 32%, and 46% at the three visits. Separate longitudinal mixed models were fitted to examine the relationship between change in HbA1c and change in fasting total cholesterol (TC), HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c), log triacylglycerols (TG), and non-HDL-cholesterol (non- HDL-c). Because of an interaction between dyslipidaemia medication use and association of HbA1c with lipids, results were stratified by dyslipidaemia medication use. Results Among patients not using dyslipidaemia medication, a higher HbA1c was associated with significantly worse levels of the lipids TC, LDL-c, TG and non-HDL-c (per 1% change in HbA1c, TC 0.101 mmol/l, 95% CI 0.050, 0.152; LDL-c 0.103 mmol/l, 95% CI 0.058, 0.148; TG 0.052 mmol/l, 95% CI 0.024, 0.081; and non-HDL-c 0.129 mmol/l, 95% CI 0.078, 0.180) but not HDL-c (−0.20 mmol/l, 95% CI −0.047, 0.007). The associations between HbA1c and any lipid outcome among those on dyslipidaemia medication were in the same direction, but attenuated compared with persons not on medication. Conclusions/interpretation Change in HbA1c is significantly associated with change in fasting lipids, but dyslipidaemia medications may be required to optimise lipid and cardiovascular health.

    "Change" is a critical dimension of contemporary experience. Library associations are not exempt, and they change in ways similar to other organizations. According to some authorities, four phases typify the process: diagnosis, design, implementation, and incorporation. Focusing on changes in the Medical Library Association's longstanding program of continuing education, the authors utilize the "phase framework" to chart that association's movement from a management system depending primarily upon volunteers to one in which professional staff figure prominently. The historical review serves a heuristic purpose for individuals and institutions in identifying characteristic features of the change process. PMID:3329921

    40 CFR Part 63, Subpart GG, the National Emission Standard for Hazardous Air Pollutants for Aerospace Manufacturing and Rework Facilities, commonly referred to as the Aerospace NESHAP, was issued on September 1, 1995 and requires compliance by September 1, 1998. The regulation affects any facility that manufactures or reworks commercial, civil, or military aircraft vehicles or components and is a major source of Hazardous Air Pollutants (HAPs). The regulation targets reducing Volatile Organic Compound (VOC) and Hazardous Air Pollutant (HAP) emissions to the atmosphere. Processes affected by the new regulation include aircraft painting, paint stripping, chemical milling masking, solvent cleaning, and spray gun cleaning. Regulatory requirements affecting these processes are summarized, and different compliance options compared in terms of cost-effectiveness and industry acceptance. Strategies to reduce compliance costs and minimize recordkeeping burdens are also presented.

    2014-01-01

    Background Medication error is common and preventable cause of medical errors and occurs as a result of either human error or a system flaw. The consequences of such errors are more harmful and frequent among pediatric patients. Objective To assess medication prescribing errors and associated factors in the pediatric wards of Dessie Referral Hospital, Northeast Ethiopia. Methods A cross-sectional study was carried out in the pediatric wards of Dessie Referral Hospital from February 17 to March 17, 2012. Data on the prescribed drugs were collected from patient charts and prescription papers among all patients who were admitted during the study period. Descriptive statistics was used to determine frequency, prevalence, means, and standard deviations. The relationship between dependent and independent variables were computed using logistic regression (with significance declared at p-value of 0.05 and 95% confidence interval). Results Out of the 384 Medication order s identified during the study, a total of 223 prescribing errors were identified. This corresponds to an overall medication prescribing error rate of 58.07%. Incomplete prescriptions and dosing errors were the two most common types of prescribing errors. Antibiotics (54.26%) were the most common classes of drugs subjected to prescribing error. Day of the week and route of administration were factors significantly associated with increased prescribing error. Conclusions Medication prescribing errors are common in the pediatric wards of Dessie Referral Hospital. Improving quick access to up to date reference materials, providing regular refresher trainings and possibly including a clinical pharmacist in the healthcare team are recommended. PMID:24826198

    Purpose The objective of this study was to identify, using the theory of planned behavior (TPB), patients’ beliefs about taking oral antidiabetic drugs (OADs) as prescribed, and to measure the correlations between beliefs and medication adherence. Patients and methods We performed a cross-sectional study of type 2 diabetic patients using structured questionnaires in a Chinese tertiary hospital. A total of 130 patients were enrolled to be interviewed about TPB variables (behavioral, normative, and control beliefs) relevant to medication adherence. Medication adherence was assessed using the eight-item Morisky Medication Adherence Scale (MMAS-8). Spearman’s rank correlation was used to assess the association between TPB and MMAS-8. Logistic regression analysis was performed to examine the relationship between different variables and MMAS-8, with statistical significance determined at P<0.05. Results From 130 eligible Chinese patients with an average age of 60.6 years and a male proportion of 50.8%, a nonsignificant relationship between behavioral, normative, and the most facilitating control beliefs and OAD adherence was found in our study. Having the OADs on hand (P=0.037) was the only facilitating control belief associated with adherence behavior. Being away from home or eating out (P=0.000), not accepting the disease (P=0.000), ignorance of life-long drug adherence (P=0.038), being busy (P=0.001), or poor memory (P=0.008) were control belief barriers found to be correlated with poor adherence. TPB is the only important determinant influencing OAD adherence among all the factors (P=0.011). Conclusion The results indicate that the TPB model could be used to examine adherence to OADs. One facilitating control belief, and most of the barrier control beliefs of TPB were related to medication adherence among Chinese type 2 diabetes inpatients. It will be helpful to understand patients’ self-medication and provide methods to develop instruments for identifying

We surveyed the editors of 33 medical journals owned by not-for-profit organizations ("associations"), including 10 journals represented on the International Committee of Medical Journal Editors (nine of which are general medical journals) and a random sample of 23 specialist journals with high impact factors that are indexed by the Institute for Scientific Information. The main outcome measures were the authority to hire, fire, and oversee the work of the editor; the editor's tenure and financial compensation; control of the journal's budget; publication of material about the association; and the editor's perceptions about editorial independence and pressure over editorial content. Of the 33 editors, 23 (70%) reported having complete editorial freedom, and the remainder reported a high level of freedom (a score of > or = 8, where 10 equals complete editorial freedom and 1 equals no editorial freedom). Nevertheless, a substantial minority of editors reported having received at least some pressure in recent years over editorial content from the association's leadership (42%), senior staff (30%), or rank-and-file members (39%). The association's board of directors has the authority to hire (48%) or fire (55%) the editor for about half of the journals, and the editor reports to the board for 10 journals (30%). Twenty-three editors (70%) are appointed for a specific term (median term = 5 years). Three-fifths of the journals have no control over their profit, and the majority of journals use the association's legal counsel and/or media relations staff. Stronger safeguards are needed to give editors protection against pressure over editorial content, including written guarantees of editorial freedom and governance structures that support those guarantees. Strong safeguards are also needed because editors

  9. Primary care physician versus urologist: how does their medical management of LUTS associated with BPH differ?

    Medical and surgical therapies for benign prostatic hyperplasia (BPH) are based largely on the results from adherence to the 2003 American Urological Association Guidelines. However, with the emergenceof medical therapies as first-line treatment and the expansion of medical therapy for lower urinary tract symptoms (LUTS) into the primary care office, the evaluation and management of men presenting with urinary symptoms can vary depending on provider type. This review explains the basis for BPH medical management in primary care with the review of three key studies. In addition, this review utilizes the data provided by the first longitudinal, observational BPH registry to evaluate patient outcomes and practice patterns in both urologist and primary care offices. From these data, we can conclude that men seeing urologists were more likely to be on medical therapy than men seeing primary care physicians (PCPs), who more often utilized watchful waiting. Urologists also were more likely to prescribe 5-alpha-reductase inhibitors (5ARIs), combination therapy with an alpha-blocker and 5ARI, and anticholinergic therapy. In contrast, the use of nonselective alpha-blockerswas appreciably greater among men seeing PCPs than men seeing urologists. PMID:19570485

    Objective Medication adherence is important in the treatment of schizophrenia, and critical periods during treatment may be associated with relapse. However, the relationship between adherence and duration of outpatient treatment (DOT) remains unclear. The authors aimed to clarify the relationship between adherence and DOT at a psychiatric hospital in Japan. Methods For outpatients with schizophrenia who regularly visit Shin-Abuyama hospital, the authors conducted a single questionnaire survey (five questions covering gender, age, DOT, medication shortages, and residual medication) over one month period. Participants were divided into two groups whether DOT were from more than one year to within five years or not. Mantel-Haenszel analysis and logistic regression analysis were performed on the data regarding the medication adherence. Results Effective answers were received for 328 patients. The residual medication rate was significantly higher among those receiving outpatient treatment from more than one year to within five years than five years than those receiving outpatient treatment for more than five years or less than one year (p=0.016). Conclusion This survey suggests that there are critical periods during which patients are most prone to poor adherence. Because poor adherence increases the risk of relapse, specific measures must be taken to improve adherence during these periods. PMID:27482242

    Early life stress (ELS) is a significant risk factor for psychopathology, although there are few functional imaging studies investigating its effects. Previous literature suggests that ELS is associated with changes in structure and function in the medial prefrontal cortex (MPFC), which forms the main anterior node of the default network (DN). This study investigated the impact of ELS history on resting state DN connectivity, using seed-based correlation analyses (SCA) involving the posterior cingulate cortex (PCC). Data were analyzed from 22 adult subjects without psychiatric or medical illness (13 with and 9 without ELS); none were taking psychotropic medication. Relative to controls, the ELS group had significant decreases in DN connectivity, observed between the PCC seed and the MPFC and inferior temporal cortex. Further analyses revealed a trend-level increase in connectivity between the amygdala and MPFC associated with ELS history. In conclusion, this study found that subjects with ELS, in the absence of psychiatric illness and medication exposure, demonstrated decreased DN connectivity, and trend-level increases in connectivity between the amygdala and MPFC. These findings suggest that altered resting state connectivity is a correlate of stress exposure, rather than a product of medication or psychiatric morbidity. PMID:23141153

    2014-11-01

    Human fallibility is pervasive in the aerospace industry with over 50% of errors attributed to human error. Consider the benefits to any organization if those errors were significantly reduced. Aerospace manufacturing involves high value, high profile systems with significant complexity and often repetitive build, assembly, and test operations. In spite of extensive analysis, planning, training, and detailed procedures, human factors can cause unexpected errors. Handling such errors involves extensive cause and corrective action analysis and invariably schedule slips and cost growth. We will discuss success stories, including those associated with electro-optical systems, where very significant reductions in human fallibility errors were achieved after receiving adapted and specialized training. In the eyes of company and customer leadership, the steps used to achieve these results lead to in a major culture change in both the workforce and the supporting management organization. This approach has proven effective in other industries like medicine, firefighting, law enforcement, and aviation. The roadmap to success and the steps to minimize human error are known. They can be used by any organization willing to accept human fallibility and take a proactive approach to incorporate the steps needed to manage and minimize error.

    Numerous aerospace applications, including low-false-alarm fire detection, environmental monitoring, fuel leak detection, and engine emission monitoring, would benefit greatly from robust and low weight, cost, and power consumption chemical microsensors. NASA Glenn Research Center has been working to develop a variety of chemical microsensors with these attributes to address the aforementioned applications. Chemical microsensors using different material platforms and sensing mechanisms have been produced. Approaches using electrochemical cells, resistors, and Schottky diode platforms, combined with nano-based materials, high temperature solid electrolytes, and room temperature polymer electrolytes have been realized to enable different types of microsensors. By understanding the application needs and chemical gas species to be detected, sensing materials and unique microfabrication processes were selected and applied. The chemical microsensors were designed utilizing simple structures and the least number of microfabrication processes possible, while maintaining high yield and low cost. In this presentation, an overview of carbon dioxide (CO2), oxygen (O2), and hydrogen/hydrocarbons (H2/CxHy) microsensors and their fabrication, testing results, and applications will be described. Particular challenges associated with improving the H2/CxHy microsensor contact wire-bonding pad will be discussed. These microsensors represent our research approach and serve as major tools as we expand our sensor development toolbox. Our ultimate goal is to develop robust chemical microsensor systems for aerospace and commercial applications.

    The way of mass reduction improving performances in the aerospace structures is a constant and relevant challenge in the space business. The designs, materials and manufacturing processes are permanently in evolution to explore and get mass optimization solutions at low cost. In the framework of ICARO project, EADS CASA ESPACIO (ECE) has designed, manufactured and tested a technology demonstrator which shows that lattice type of grid structures is a promising weight saving solution for replacing some traditional metallic and composite structures for space applications. A virtual testing methodology was used in order to support the design of a high modulus CFRP cylindrical lattice technology demonstrator. The manufacturing process, based on composite Automatic Fiber Placement (AFP) technology developed by ECE, allows obtaining high quality low weight lattice structures potentially applicable to a wide range of aerospace structures. Launcher payload adaptors, satellite platforms, antenna towers or instrument supports are some promising candidates.

    Magnetic gearboxes are contactless mechanisms for torque-speed conversion. They present no wear, no friction and no fatigue. They need no lubricant and can be customized for other mechanical properties as stiffness or damping. Additionally, they can protect structures and mechanisms against overloads, limitting the transmitted torque. In this work, spur, planetary and "magdrive" or "harmonic drive" configurations are compared considering their use in aerospace applications. The most recent test data are summarized to provide some useful help for the design engineer.

    This paper describes the design, development, testing, and performance at Ball Aerospace of a long-life hybrid (combination of Stirling and Joule-Thomson [J-T] thermodynamic cycles) space cryocooler. Hybrid coolers are synergistic combinations of two thermodynamic cycles that combine advantages of each cycle to yield overall improved performance. Hybrid cooler performance advantages include: 1) load leveling of large heat loads; 2) remote cryogenic cooling with very low to negligible induced vibration and jitter; 3) very low redundant (off state) cooler penalties; 4) high power efficiency, especially at low temperatures; and 5) simplified system integration with capability to cross gimbals and no need for thermal straps or switches. Ball Aerospace is currently developing several different hybrid cooler systems. The 35 K hybrid cooler provides 2.0 W at 35 K and 8.5 W at 85 K with an emphasis on load leveling of high transient heat loads and remote, low vibration cooling. The 10 K hybrid cooler provides 200 mW at 10 K, 700 mW at 15 K, and 10.7 W at 85 K with an emphasis on power efficiency. In addition, Ball Aerospace built and tested a complete hybrid cooler that met the requirements of the JWST Mid-Infrared Instrument (MIRI) cooler including providing 80 mW at 6 K and 100 mW at 18 K for a total system (28 V) power of 310 W.

    The increasing prevalence of abnormal body mass index (BMI), mainly obesity, is becoming a significant public health problem. This cross-sectional study aimed to provide a comprehensive view of secular trends of BMI, and the associated socio-demographic variables and comorbidities among adolescents with abnormal BMI. Individuals of the study population were born mainly between 1970 and 1993, and were examined at 16 to 19 years of age during the years 1987 to 2010, at 1 conscription center in the northern district of Israel.The study population included 113,694 adolescents. Univariate and multivariable logistic regression models were used to investigate the associations between BMI categories, socio-demographic variables, and medical conditions.A downward trend in the prevalence of normal BMI among both male and female adolescents was obtained, while trends of overweight and obesity (in both genders) and underweight (only among females) rose. Socio-demographic variables such as religion, education, family-related parameters, residential environment, country of birth, and origin were all associated with different risks for abnormal BMI. Obesity was associated with higher risk for hyperlipidemia, endocrine disorders (only in males), knee disorders, and hypertension type I + II (in both genders). Overweight was associated with knee disorders (only in females). Underweight, exclusively in males, was associated with increased risk for endocrine disorders, proteinuria, and cardiac disorders. Hierarchical clustering analysis revealed the intricate relations between gender, BMI, and medical signatures. It brought to light novel clusters of diseases that were abundant among populations having above-normal BMI or underweight males. Furthermore, above-normal BMI was associated with a lower rate of cardiac anomalies and scoliosis/kyphosis, whereas being underweight was associated with a lower risk for hypertension and flat foot.This study provides a reliable and in-depth view

    Electronic health record (EHR) systems offer an exceptional opportunity for studying many diseases and their associated medical conditions within a population. The increasing number of clinical record entries that have become available electronically provides access to rich, large sets of patients' longitudinal medical information. By integrating and comparing relations found in the EHRs with those already reported in the literature, we are able to verify existing and to identify rare or novel associations. Of particular interest is the identification of rare disease co-morbidities, where the small numbers of diagnosed patients make robust statistical analysis difficult. Here, we introduce ADAMS, an Application for Discovering Disease Associations using Multiple Sources, which contains various statistical and language processing operations. We apply ADAMS to the New York-Presbyterian Hospital's EHR to combine the information from the relational diagnosis tables and textual discharge summaries with those from PubMed and Wikipedia in order to investigate the co-morbidities of the rare diseases Kaposi sarcoma, toxoplasmosis, and Kawasaki disease. In addition to finding well-known characteristics of diseases, ADAMS can identify rare or previously unreported associations. In particular, we report a statistically significant association between Kawasaki disease and diagnosis of autistic disorder. PMID:21731656

    We investigated the association between seafood consumption and symptoms related to potential mercury toxicity in patients presenting to specialty medical clinics at Stony Brook Medical Center on Long Island, New York. We surveyed 118 patients from April–August 2012 about their seafood consumption patterns, specifically how frequently they were eating each type of fish, to assess mercury exposure. We also asked about symptoms associated with mercury toxicity including depression, fatigue, balance difficulties, or tingling around the mouth. Of the 118 adults surveyed, 14 consumed high mercury seafood (tuna steak, marlin, swordfish, or shark) at least weekly. This group was more likely to suffer from fatigue than other patients (p = 0.02). Logistic regression confirmed this association of fatigue with frequent high mercury fish consumption in both unadjusted analysis (OR = 5.53; 95% CI: 1.40–21.90) and analysis adjusted for age, race, sex, income, and clinic type (OR = 7.89; 95% CI: 1.63–38.15). No associations were observed between fish intake and depression, balance difficulties, or tingling around the mouth. Findings suggest that fatigue may be associated with eating high mercury fish but sample size is small. Larger studies are needed to determine whether fish intake patterns or blood mercury tests warrant consideration as part of the clinical work-up in coastal regions. PMID:26844152

    Toxicology dates to the very earliest history of humanity with various poisons and venom being recognized as a method of hunting or waging war with the earliest documentation in the Evers papyrus (circa 1500 BCE). The Greeks identified specific poisons such as hemlock, a method of state execution, and the Greek word toxos (arrow) became the root of our modern science. The first scientific approach to the understanding of poisons and toxicology was the work during the late middle ages of Paracelsus. He formulated what were then revolutionary views that a specific toxic agent or "toxicon" caused specific dose-related effects. His principles have established the basis of modern pharmacology and toxicology. In 1700, Bernardo Ramazzini published the book De Morbis Artificum Diatriba (The Diseases of Workers) describing specific illnesses associated with certain labor, particularly metal workers exposed to mercury, lead, arsenic, and rock dust. Modern toxicology dates from development of the modern industrial chemical processes, the earliest involving an analytical method for arsenic by Marsh in 1836. Industrial organic chemicals were synthesized in the late 1800 s along with anesthetics and disinfectants. In 1908, Hamilton began the long study of occupational toxicology issues, and by WW I the scientific use of toxicants saw Haber creating war gases and defining time-dosage relationships that are used even today.

    2014-01-01

    Background and Objective Recently, use of prescription opioids (POs) has increased; non-medical PO (NMPO) use is linked to overdose. NMPO use is common among individuals prescribed opioids for pain, and those in Substance Use Disorder (SUD) treatment with pain could be at increased risk for unintentional overdose due to NMPO use. We examined associations between pain, NMPO use, and overdose among SUD treatment patients. Methods Among 342 patients at a residential SUD treatment center, logistic regression examined the association of overdose with pain, adjusting for substance use, suicide attempts, and demographics. Results Pain was positively related to NMPO use. Heroin use, suicide attempts, pain, and NMPO use were positively associated with overdose; but NMPO use attenuated the pain-overdose relationship. Conclusions The relationship between pain and overdose among substance users may be, in part, explained by the association between pain and heavy NMPO use. PMID:24313240

    The appeal of online education and distance learning as an educational alternative is ever increasing. To support and accommodate the over-specialized knowledge available by different experts, information technology can be employed to develop virtual distributed pools of autonomous specialized educational modules and provide the mechanisms for retrieving and sharing them. New educational standards such as SCORM and Healthcare LOM enhance this process of sharing by offering qualities like interoperability, accessibility, and reusability, so that learning material remains credible, up-to-date and tracks changes and developments of medical techniques and standards through time. Given that only a few e-learning courses exist in aerospace medicine the material of which may be exchanged among teachers, the aim of this paper is to illustrate the procedure of creating a SCORM compliant course that incorporates notions of recent advances in social web technologies. The course is in accordance with main educational and technological details and is specific to pulmonary disorders in aerospace medicine. As new educational trends place much emphasis in continuing medical education, the expansion of a general practitioner's knowledge in topics such as aviation and aerospace pulmonary disorders for crew and passengers becomes a societal requirement.

We used a consensus process to develop the EMS-SI, which was designed to capture three composite measurements of EMS worker injury, medical errors and adverse events (AE), and safety compromising behaviors. We used hierarchical logistic regression to test the association between poor sleep quality, fatigue, and three composite measures of EMS worker safety outcomes. Results We received 547 surveys from 30 EMS agencies (a 35.6% mean agency response rate). The mean PSQI score exceeded the benchmark for poor sleep (6.9, 95%CI 6.6, 7.2). Greater than half of respondents were classified as fatigued (55%, 95%CI 50.7, 59.3). Eighteen percent of respondents reported an injury (17.8%, 95%CI 13.5, 22.1), forty-one percent a medical error or AE (41.1%, 95%CI 36.8, 45.4), and 89% (95%CI 87, 92) safety compromising behaviors. After controlling for confounding, we identified 1.9 greater odds of injury (95%CI 1.1, 3.3), 2.2 greater odds of medical error or AE (95%CI 1.4, 3.3), and 3.6 greater odds of safety compromising behavior (95%CI 1.5, 8.3) among fatigued respondents versus non-fatigued respondents. Conclusions In this sample of EMS workers, poor sleep quality and fatigue is common. We provide preliminary evidence of an association between sleep quality, fatigue, and safety outcomes.

    Child sexual abuse (CSA) affects over 62,000 children annually in the United States. A primary obstacle to the success of a public health prevention strategy is the lack of knowledge around community level risk factors for CSA. We evaluated community level characteristics for children seeking care for suspected CSA in the Greater Houston area for 2009. There was a total incidence rate of medical evaluations for suspected CSA of 5.9/1000 children. We abstracted the medical charts of 1982 (86 %) children who sought a medical evaluation for suspected CSA at three main medical systems in the Greater Houston area for 2009. We evaluated 18 community level variables from the American Community Survey for the 396 zip codes these children lived in. The mean number of cases per Greater Houston zip code was 2.77 (range 0-27), with 62 % of zip codes not having a case at any of the three sites surveyed. Zip codes with a higher than Houston average rate of vacant houses, never married females and unemployed labor force with high family poverty rate, were associated with an increased rate of children seeking care for suspected CSA. We demonstrated zip codes level characteristics which were associated with an increased rate of children seeking care for suspected CSA. Our modelling process and our data have implications for community based strategies aimed at improved surveillance or prevention of CSA. The process of identifying locally specific community level factors suggests target areas which have particular socioeconomic characteristics which are associated with increased rate of seeking CSA evaluations.

    As future physicians capable of controlling tobacco dependence in the population, medical students are considered a main target for tobacco control interventions. This cross-sectional study reported on the prevalence of tobacco use (cigarettes and waterpipes) and associated knowledge and behaviour among 6th-year medical students in 2009-2010 from 6 medical schools in Lebanon. The self-administered questionnaire based on the Global Health Professional Survey (GHPSS) core questions also enquired about training in tobacco cessation approaches. All enrolled students were asked to participate; the response rate was 191/354 (54.3%). The prevalence of tobacco use was 26.3% for cigarettes and 29.5% for waterpipes. Smoking waterpipes was the only significant predictor for cigarette smoking and there was no difference by sex and socioeconomic status. A minority reported ever receiving any formal training in treatment approaches for tobacco dependence. Medical schools should include tobacco dependence treatment training programmes in their curriculum and discourage tobacco use. PMID:24313150

    Objective To assess guideline adherence of co-prescribing NSAID and gastroprotective medications for elders in general practice over time, and investigate its potential association with the electronic medical record (EMR) system brand used. Methods We included patients 65 years and older who received NSAIDs between 2005 and 2010. Prescription data were extracted from EMR systems of GP practices participating in the Dutch NIVEL Primary Care Database. We calculated the proportion of NSAID prescriptions with co-prescription of gastroprotective medication for each GP practice at intervals of three months. Association between proportion of gastroprotection, brand of electronic medical record (EMR), and type of GP practice were explored. Temporal trends in proportion of gastroprotection between electronic medical records systems were analyzed using a random effects linear regression model. Results We included 91,521 patient visits with NSAID prescriptions from 77 general practices between 2005 and 2010. Overall proportion of NSAID prescriptions to the elderly with co-prescription of gastroprotective medication was 43%. Mean proportion of gastroprotection increased from 27% (CI 25–29%) in the first quarter of 2005 with a rate of 1.2% every 3 months to 55%(CI 52–58%) at the end of 2010. Brand of EMR and type of GP practice were independently associated with co-prescription of gastroprotection. Conclusion Although prescription of gastroprotective medications to elderly patients who receive NSAIDs increased in The Netherlands, they are not co-prescribed in about half of the indicated cases. Brand of EMR system is associated with differences in prescription of gastroprotective medication. Optimal design and utilization of EMRs is a potential area of intervention to improve quality of prescription. PMID:26110650

    Background In Japan, there is a shortage of young physicians in various specialties; the present situation of general medicine or family medicine (GM/FM) in particular is risky. The factors influencing the career choice of Japanese medical students are poorly understood. This study aims to identify factors related to choosing GM/FM as a career. Methods The study was designed as a cross-sectional survey. Students at one medical school in Japan filled out a questionnaire. Students were asked to state their intended medical specialty, and they rated the importance of specific individual and occupational aspects using a 4-point likert scale. Factor analysis was performed on the variables. Reliability of the factor scores was estimated using Cronbach‘s alpha coefficients; biserial correlations between the factors and career choices were calculated. Furthermore, multiple linear regression analysis was performed using career choice (GM/FM vs. others) as the criterion variable and the factors plus demographic characteristics as confounding variables. Results Factor analysis produced six factors that explained future career plans. Medical students in this study had a positive and realistic idea about GM/FM, but only 18.8% of them chose GM/FM first as a career. The significant variables associated with choosing GM/FM first as a career were: ‘Admission from hometown’ (β=0.189, P=0.001), ‘Student preparing for the entrance exam’ (β=0.172; P=0.001), ‘Intent for rural practice’ (β=0.123, P=0.016), and ‘Work–life balance’ (β=0.126, P=0.013). While significant variables that were negatively associated with choosing GM/FM were ‘Presence of medical relatives’ (β=−0.107, P=0.037) and ‘Scientific orientation’ (β=−0.125, P=0.013). Conclusions Strategies have been suggested, such as recruiting medical students with significant variables that were associated with choosing GM/FM first as a career. By engaging students early in their choice of career

    Objective The use of psychotropic medications in Alzheimer’s disease (AD) has been associated with both deleterious and potentially beneficial outcomes. We examined the longitudinal association of psychotropic medication use with cognitive, functional, and neuropsychiatric symptom (NPS) trajectories among community-ascertained incident AD cases from the Cache County Dementia Progression Study. Methods A total of 230 participants were followed for a mean of 3.7 years. Persistency index (PI) was calculated for all antidepressants, selective serotonin reuptake inhibitors (SSRIs), antipsychotics (atypical and typical), and benzodiazepines as the proportion of observed time of medication exposure. Mixed-effects models were used to examine the association between PI for each medication class and Mini-Mental State Exam (MMSE), Clinical Dementia Rating Sum of Boxes (CDR-Sum), and Neuropsychiatric Inventory – Total (NPI-Total) trajectories, controlling for appropriate demographic and clinical covariates. Results At baseline, psychotropic medication use was associated with greater severity of dementia and poorer medical status. Higher PI for all medication classes was associated with a more rapid decline in MMSE. For antidepressant, SSRI, benzodiazepine, and typical antipsychotic use, a higher PI was associated with a more rapid increase in CDR-Sum. For SSRIs, antipsychotics, and typical antipsychotics, a higher PI was associated with more rapid increase in NPI-Total. Conclusions Psychotropic medication use was associated with more rapid cognitive and functional decline in AD, and not with improved NPS. Clinicians may tend to prescribe psychotropic medications to AD patients at risk of poorer outcomes, but one cannot rule out the possibility of poorer outcomes being caused by psychotropic medications.

    OBJECTIVES: To assess the prevalence and levels of burnout syndrome among medical students at the Universidade Federal de Sergipe-Brazil and to identify associated factors. METHODS: A cross-sectional study was performed with randomly selected students in 2009. The Maslach Burnout Inventory/Student Survey (MBI-SS) and a structured questionnaire on socio-demographic characteristics, the educational process, and individual aspects were used. Statistical evaluation of multiple variables was performed through backward stepwise logistic regression analysis. RESULTS: The prevalence of burnout was 10.3% (n = 369). The prevalence was higher among those who did not have confidence in their clinical skills (Odds Ratio–OR = 6.47), those who felt uncomfortable with course activities (OR = 5.76), and those who did not see the coursework as a source of pleasure (OR = 4.68). CONCLUSION: There was a significant prevalence of burnout among the medical students studied. Three variables, in particular, were associated with burnout and were directly related to the medical education process. Preventive and intervention measures must be adopted, and longitudinal studies should be conducted. PMID:22760894

    Medical conditions related to hormonal abnormalities were investigated in a case-control study of breast cancer among women who attended a screening centre. Information was obtained by telephone interview regarding physician-diagnosed medical conditions such as thyroid or liver diseases, diabetes, and hypertension, as well as hirsutism, acne, galactorrhoea, and reproductive, menstrual, and gynaecological factors. Results are presented for 354 cases and 747 controls. Women with fertility problems who never succeeded in becoming pregnant were at significantly increased breast cancer risk (adjusted odds ratio [OR] = 3.5; 95% confidence interval [CI]:1.1-10.9). An elevated cancer risk was also associated with having excess body hair (OR = 1.5; 95% CI:1.0-2.3), or having excess body hair in addition to persistent adult acne (OR = 6.8; 95% CI:1.7-27.1). Recurrent amenorrhea (OR = 3.5; 95% CI:1.1-11.5), and a treated hyperthyroid condition (OR = 2.2; 95% CI:1.1-4.4) were significantly associated with risk. A non-significant elevation of risk was present for endometrial hyperplasia (OR = 1.8; 95% CI: 0.8-4.0). There was a suggestion of an association between a history of galactorrhoea and breast cancer risk (OR = 2.0; 95% CI:0.8-4.9) among premenopausal women. No associations were found with other medical or gynaecological factors. The possibility that some of these findings are due to chance cannot be excluded because of the problem of multiple comparisons. PMID:8144280

    Diabetes is a global epidemic, associated with a high burden of complications and 4.6 million deaths annually worldwide. As a result of decreasing levels of physical activity and increasing rates of obesity, diabetes is shifting from a disease affecting the elderly to one that affects younger patients or even children. Thus, aggressive treatment and optimal control of risk factors is the key to improve outcomes in those patients. Accumulating evidence of the cardiovascular and lipid effects of glucose-lowering medications suggest that treatment efficacy in diabetes can be further improved. This review provides an overview of the lipid effects and cardiovascular disease risk of current anti-diabetic medications and highlights opportunities and challenges in clinical practice.

    The mission of the Association of American Veterinary Medical Colleges (AAVMC) is to advance the quality of academic veterinary medicine. Founded in 1966 by the 18 US colleges of veterinary medicine and 3 Canadian colleges of veterinary medicine then in existence, the AAVMC is celebrating 50 years of public service. Initially, the AAVMC comprised the Council of Deans, the Council of Educators, and the Council of Chairs. In 1984, the tri-cameral structure was abandoned and a new governing structure with a board of directors was created. In 1997, the AAVMC was incorporated in Washington, DC and a common application service was created. Matters such as workforce issues and the cost of veterinary medical education have persisted for decades. The AAVMC is a champion of diversity in the veterinary profession and a strong advocate for One Health. The AAVMC has adopted a global perspective as more international colleges of veterinary medicine have earned COE accreditation and become members. PMID:26673207

    Abstract Background Epidemiological studies have consistently reported rates of posttraumatic stress disorder (PTSD) in women that are twice that of men. In men and women, PTSD has been associated with comorbid medical conditions, medical symptoms and lower self-rating of health. In low-income urban women, rates of PTSD are even more elevated than in suburban women and may be related to observed health disparities. Methods In this study, 250 women seeking healthcare at an urban clinic were interviewed for a PTSD diagnosis, major depressive disorder (MDD), the experience of traumatic events, the experience of current and past common medical conditions and symptoms, and subjective rating of health. A chart review was used to assess healthcare use in the past year. Results More current (5.2 vs. 3.8, p < 0.05) and past medical conditions (4.6 vs. 3.3, p < 0.05) were reported by women with a lifetime history of PTSD than by women without this history, after controlling for demographics and current depression. Women with lifetime PTSD also had more annual clinic appointments (5.9 vs. 3.8 p < 0.03) and were 2.4 times (p < 0.05) more likely to report lower appraisal of their physical health. Conclusions These findings suggest that urban health-seeking women with PTSD experience health impairments that may cause increased morbidity and that healthcare providers should consider the health ramifications of PTSD when providing medical care to women.

    Background: Almost all institutions, colleges, universities and homes today were using computer regularly. Very little research has been carried out on Indian users especially among college students the effects of computer use on the eye and vision related problems. Aim: The aim of this study was to assess the prevalence of computer vision syndrome (CVS) among medical and engineering students and the factors associated with the same. Subjects and Methods: A cross-sectional study was conducted among medical and engineering college students of a University situated in the suburban area of Chennai. Students who used computer in the month preceding the date of study were included in the study. The participants were surveyed using pre-tested structured questionnaire. Results: Among engineering students, the prevalence of CVS was found to be 81.9% (176/215) while among medical students; it was found to be 78.6% (158/201). A significantly higher proportion of engineering students 40.9% (88/215) used computers for 4-6 h/day as compared to medical students 10% (20/201) (P < 0.001). The reported symptoms of CVS were higher among engineering students compared with medical students. Students who used computer for 4-6 h were at significantly higher risk of developing redness (OR = 1.2, 95% CI = 1.0-3.1,P = 0.04), burning sensation (OR = 2.1,95% CI = 1.3-3.1, P < 0.01) and dry eyes (OR = 1.8, 95% CI = 1.1-2.9, P = 0.02) compared to those who used computer for less than 4 h. Significant correlation was found between increased hours of computer use and the symptoms redness, burning sensation, blurred vision and dry eyes. Conclusion: The present study revealed that more than three-fourth of the students complained of any one of the symptoms of CVS while working on the computer. PMID:24761234

  11. Managing complexity of aerospace systems

    NASA Astrophysics Data System (ADS)

    Tamaskar, Shashank

    Growing complexity of modern aerospace systems has exposed the limits of conventional systems engineering tools and challenged our ability to design them in a timely and cost effective manner. According to the US Government Accountability Office (GAO), in 2009 nearly half of the defense acquisition programs are expecting 25% or more increase in unit acquisition cost. Increase in technical complexity has been identified as one of the primary drivers behind cost-schedule overruns. Thus to assure the affordability of future aerospace systems, it is increasingly important to develop tools and capabilities for managing their complexity. We propose an approach for managing the complexity of aerospace systems to address this pertinent problem. To this end, we develop a measure that improves upon the state-of-the-art metrics and incorporates key aspects of system complexity. We address the problem of system decomposition by presenting an algorithm for module identification that generates modules to minimize integration complexity. We demonstrate the framework on diverse spacecraft and show the impact of design decisions on integration cost. The measure and the algorithm together help the designer track and manage complexity in different phases of system design. We next investigate how complexity can be used as a decision metric in the model-based design (MBD) paradigm. We propose a framework for complexity enabled design space exploration that introduces the idea of using complexity as a non-traditional design objective. We also incorporate complexity with the component based design paradigm (a sub-field of MBD) and demonstrate it on several case studies. The approach for managing complexity is a small but significant contribution to the vast field of complexity management. We envision our approach being used in concert with a suite of complexity metrics to provide an ability to measure and track complexity through different stages of design and development.

    The advent of internet-based delivery of basic medical science lectures may unintentionally lead to decreased classroom attendance and participation, thereby creating a distance learning paradigm. In this study, we tested the hypothesis that classroom attendance/participation may be positively correlated with performance on a written examination for first-year medical school instruction. The study subjects consisted of 115 first-year medical students. The introductory respiratory structure-function instruction was designed to include one noncompulsory pretest, four short postinstruction noncompulsory self-evaluation tests that were unannounced as to date and time, and one compulsory comprehensive examination. The relationship between attendance/participation, measured by the number of noncompulsory tests taken, and performance on the comprehensive examination was determined by Pearson's correlation coefficient, one-way ANOVA, and a chi(2)-test of significance. The average score on the pretest was 28%; for the same items on the comprehensive examination (posttest), the average score was 73%. For the 80 students who took the pretest, this translated to an overall score increase of 161%. Attendance/participation in four or five of the noncompulsory tests resulted in an 83.3% pass rate on the comprehensive exam compared with a rate of 52.9% for attendance/participation in three, two, one, or none of the five noncompulsory tests; the overall pass rate was 60.9%. There was a significant association between a high rate of classroom attendance/participation and a high score on the comprehensive examination (Pearson's chi(2) = 8.599, P < 0.01). These findings suggest that classroom attendance/participation may be a significant determinant of performance of medical students on comprehensive examinations in first-year basic medical science courses. It is concluded that a substantial number of first-year medical students in this study could be at risk for poor performance

    Objective Physicians play a critical role in addressing tobacco dependence, yet report limited training. Tobacco dependence treatment curricula for medical students could improve performance in this area. This study identified student and medical school tobacco treatment curricula characteristics associated with intentions and use of the 5As for tobacco treatment among 3rd year U.S. medical students. Methods Third year medical students (N=1065, 49.3% male) from 10 U.S. medical schools completed a survey in 2009-2010 assessing student characteristics, including demographics, tobacco treatment knowledge, and self-efficacy. Tobacco curricula characteristics assessed included amount and type of classroom instruction, frequency of tobacco treatment observation, instruction, and perception of preceptors as role models. Results Greater tobacco treatment knowledge, self-efficacy, and curriculum-specific variables were associated with 5A intentions, while younger age, tobacco treatment self-efficacy, intentions, and each curriculum-specific variable was associated with greater 5A behaviors. When controlling for important student variables, greater frequency of receiving 5A instruction (OR = 1.07; 95%CI 1.01-1.12) and perception of preceptors as excellent role models in tobacco treatment (OR = 1.35; 95%CI 1.04-1.75) were significant curriculum predictors of 5A intentions. Greater 5A instruction (B = .06 (.03); p< .05) and observation of tobacco treatment (B= .35 (.02); p< .001) were significant curriculum predictors of greater 5A behaviors. Conclusions Greater exposure to tobacco treatment teaching during medical school is associated with both greater intentions to use and practice tobacco 5As. Clerkship preceptors, or those physicians who provide training to medical students, may be particularly influential when they personally model and instruct students in tobacco dependence treatment.

    Objectives Off-label medication use for treating cognitive impairments and neuropsychiatric symptoms occurs in frontotemporal dementia (FTD) and Alzheimer’s disease (AD). We compared use of cognitive and psychiatric medications in FTD and AD and evaluated the relationship between neuropsychiatric symptoms and medication use. Methods Cognitive and psychiatric medication use, demographic variables and Neuropsychiatric Inventory (NPI) subscale symptoms were obtained from the National Alzheimer’s Coordinating Center Uniform Data Set (n=3958, 8.1% FTD). Bivariate statistics and logistic regressions were calculated to evaluate which demographic or NPI subscale symptoms predicted medication use. Results Although cognitive medication was used more commonly in AD (78%) it was also commonly used off-label in FTD (56%). Psychiatric medications were in greater use in FTD than AD (68 vs. 45%, respectively, p<0.001). In FTD, cognitive medication use was associated with elevated NPI elation scores and psychiatric medication use was associated with history of prior psychiatric disease. In AD, demographic variables (white, longer disease duration, higher education, more severe disease or being male) were most predictive of cognitive medication use while having psychiatric disease, being white, having longer disease duration, being younger, greater disease severity, being disinhibited or anxious were associated with psychiatric medication use. Off-label antipsychotics were used in 4.7% of patients with AD and 10% of patients with FTD. Conclusions Our results revealed significant off-label medication use in both FTD and AD. A notable finding from this study was the lack of consistent relationships between medication use and neuropsychiatric symptoms across the two illnesses. PMID:23995817

    2015-05-01

    High profile breaches have occurred across numerous information systems. One area where attacks are particularly problematic is autonomous control systems. This paper considers the aerospace information system, focusing on elements that interact with autonomous control systems (e.g., onboard UAVs). It discusses the trust placed in the autonomous systems and supporting systems (e.g., navigational aids) and how this trust can be validated. Approaches to remotely detect the UAV compromise, without relying on the onboard software (on a potentially compromised system) as part of the process are discussed. How different levels of autonomy (task-based, goal-based, mission-based) impact this remote characterization is considered.

    2010-01-01

    Pressurized and sealed aerospace payloads can leak on orbit. When dealing with toxic or hazardous materials, requirements for fluid and gas leakage rates have to be properly established, and most importantly, reliably verified using the best Nondestructive Test (NDT) method available. Such verification can be implemented through application of various leak test methods that will be the subject of this paper, with a purpose to show what approach to payload leakage rate requirement verification is taken by the National Aeronautics and Space Administration (NASA). The scope of this paper will be mostly a detailed description of 14 leak test methods recommended.

    2012-06-01

    Two decades of extensive investment in nanomaterials, nanofabrication and nanometrology have provided the global engineering community a vast array of new technologies. These technologies not only promise radical change to traditional industries, such as transportation, information and aerospace, but may create whole new industries, such as personalized medicine and personalized energy harvesting and storage. The challenge today for the defense aerospace community is determining how to accelerate the conversion of these technical opportunities into concrete benefits with quantifiable impact, in conjunction with identifying the most important outstanding scientific questions that are limiting their utilization. For example, nanomaterial fabrication delivers substantial tailorablity beyond a traditional material data sheet. How can we integrate this tailorability into agile manufacturing and design methods to further optimize the performance, cost and durability of future resilient aerospace systems? The intersection of nano-based metamaterials and nanostructured devices with biotechnology epitomizes the technological promise of autonomous systems and enhanced human-machine interfaces. What then are the key materials and processes challenges that are inhibiting current lab-scale innovation from being integrated into functioning systems to increase effectiveness and productivity of our human resources? Where innovation is global, accelerating the use of breakthroughs, both for commercial and defense, is essential. Exploitation of these opportunities and finding solutions to the associated challenges for defense aerospace will rely on highly effective partnerships between commercial development, scientific innovation, systems engineering, design and manufacturing.

  1. Ethical challenges in emergency medical services. A special contribution of the Ethics Committee, National Association of Emergency Medical Services Physicians.

    PubMed

    1993-01-01

    Patient autonomy, beneficence, and justice are the fundamental ethical principles of an emergency medical service. Ethical conflicts are present in the daily practice of prehospital care. These conflicts surround issues of resuscitation, futile therapy, consent, and refusal of care, duty, and confidentiality. Emergency medical services must remain fair and equitable, equally available to those it is designed to serve, regardless of the patient's social or economic status. Establishing priorities for patient care is dictated by medical and operational concerns. Education and information regarding ethical issues are important for the providers of prehospital medical care as well as the medical director. Policies and protocols must continue to be developed to address requests to limit resuscitation, such as refusal of care and patient confidentiality. Policies should be developed in conjunction with experienced legal advice. Current training does not equip even the most advanced prehospital care provider to deal easily with every potential situation. Many learn by experience, some are guided by clear policy. Ideally, medical control personnel will be educated, interested, and available to address dilemmas which arise. Where possible, policies and procedures should be developed to address ethical issues which are likely to be faced by EMS personnel. PMID:10155466

    This study aims to examine the associations between comorbid conditions and healthcare utilization, medical charges, or mortality of patients with rheumatoid arthritis (RA). Nebraska state emergency department (ED) discharge, hospital discharge, and death certificate data from 2007 to 2012 were used to study the comorbid conditions of patients with RA. RA was defined using the standard International Classification of Diseases (ICD-9-CM 714 or ICD-10-CM M05, M06, and M08). There were more comorbid conditions in patients with RA than in patients without RA. Comorbid conditions were majorly related to healthcare utilization and mortality of patients with RA. In addition to injury, fracture, sprains, and strains, symptoms of cardiovascular and digestive systems, respiratory infection, and chronic obstructive pulmonary disease (COPD) were common comorbid conditions for ED visits. In addition to joint replacement and fracture, infections, COPD and cardiovascular comorbidities were common comorbid conditions for hospitalizations. Cardiovascular, cerebrovascular, and respiratory comorbidities, dementia, malignant neoplasm, and diabetes mellitus were common comorbid conditions for deaths of patients with RA. In addition, the numbers of comorbid conditions were significantly associated with the length of hospital stay and hospital charges for patients with RA. The findings in this study indicated that comorbid conditions are associated with healthcare utilization, medical charges, and mortality of patients with RA. PMID:27106546

    Background As socioeconomic health inequalities persist and widen, the health effects of adversity are a constant presence in the daily work of physicians. Gruen and colleagues suggest that, in responding to important population health issues such as this, defining those areas of professional obligation in contrast to professional aspiration should be on the basis of evidence and feasibility. Drawing this line between obligation and aspiration is a part of the work of professional medical colleges and associations, and in doing so they must respond to members as well as a range of other interest groups. Our aim was to explore the usefulness of Gruen's model of physician responsibility in defining how professional medical colleges and associations should lead the profession in responding to socioeconomic health inequalities. Methods We report a case study of how the Royal Australian College of General Practitioners is responding to the issue of health inequalities through its work. We undertook a consultation (80 interviews with stakeholders internal and external to the College and two focus groups with general practitioners) and program and policy review of core programs of College interest and responsibility: general practitioner training and setting of practice standards, as well as its work in public advocacy. Results Some strategies within each of these College program areas were seen as legitimate professional obligations in responding to socioeconomic health inequality. However, other strategies, while potentially professional obligations within Gruen's model, were nevertheless contested. The key difference between these lay in different moral orientations. Actions where agreement existed were based on an ethos of care and compassion. Actions that were contested were based on an ethos of justice and human rights. Conclusion Colleges and professional medical associations have a role in explicitly leading a debate about values, engaging both external

  5. Motivational profiles of medical students: Association with study effort, academic performance and exhaustion

    PubMed Central

    2013-01-01

    Background Students enter the medical study with internally generated motives like genuine interest (intrinsic motivation) and/or externally generated motives like parental pressure or desire for status or prestige (controlled motivation). According to Self-determination theory (SDT), students could differ in their study effort, academic performance and adjustment to the study depending on the endorsement of intrinsic motivation versus controlled motivation. The objectives of this study were to generate motivational profiles of medical students using combinations of high or low intrinsic and controlled motivation and test whether different motivational profiles are associated with different study outcomes. Methods Participating students (N = 844) from University Medical Center Utrecht, the Netherlands, were classified to different subgroups through K-means cluster analysis using intrinsic and controlled motivation scores. Cluster membership was used as an independent variable to assess differences in study strategies, self-study hours, academic performance and exhaustion from study. Results Four clusters were obtained: High Intrinsic High Controlled (HIHC), Low Intrinsic High Controlled (LIHC), High Intrinsic Low Controlled (HILC), and Low Intrinsic Low Controlled (LILC). HIHC profile, including the students who are interest + status motivated, constituted 25.2% of the population (N = 213). HILC profile, including interest-motivated students, constituted 26.1% of the population (N = 220). LIHC profile, including status-motivated students, constituted 31.8% of the population (N = 268). LILC profile, including students who have a low-motivation and are neither interest nor status motivated, constituted 16.9% of the population (N = 143). Interest-motivated students (HILC) had significantly more deep study strategy (p < 0.001) and self-study hours (p < 0.05), higher GPAs (p < 0.001) and lower exhaustion (p < 0.001) than status

    Objective: Although binge eating disorder (BED) is the most prevalent eating disorder, the impact of untreated BED is underappreciated. This review describes the relationship of BED to physical and mental health, quality of life, and functionality. Data Sources: PubMed searches were conducted on March 21, 2014; searches were limited to English-language research articles, meta-analyses, and reviews published between January 1, 2003 and March 21, 2014. Search terms included (binge eating OR binge-eating OR binge eating disorder) AND (cardiovascular OR metabolic OR metabolic syndrome OR gastrointestinal OR health OR rehabilitation OR recovery OR sleep OR pregnancy OR quality of life OR functional impairment OR activities of daily living OR QoL OR SF-12 OR ED-5D OR SF-36 OR psychosocial OR depressive OR anxiety OR self-esteem OR suicidality OR suicide OR productivity OR family). Study Selection/Data Extraction: Of 326 identified publications, 43 were relevant to the topic and reported on the association of BED with psychiatric and medical comorbidities, quality of life, and functional outcomes. Results: Individuals diagnosed with BED have increased rates of mental health comorbidities (eg, depression and anxiety) and more pronounced medical impairments (eg, cardiovascular disorders) compared with individuals without BED. BED is also associated with functional impairment and reduced quality of life. Conclusions: Binge eating disorder is associated with impairments in physical and mental health, which can decrease quality of life and functionality and lead to increased health care utilization and decreased productivity. However, some caution is warranted in interpreting these findings because it remains unclear whether BED is an antecedent condition, a complication associated with a comorbid psychiatric condition, or an unrelated feature that occurs concurrently with these comorbidities and impairments. Much of the research on BED is based on observational or

    Objective The purpose of this lecture was to review the development of the Medical Library Association (MLA) oral history program and to highlight the oral histories of thirty-seven past MLA presidents to identify themes of common interest and relevance to current MLA members. Methods The lecture focused on three main topics discussed in many of the interviews: the presidents' backgrounds and how they came to be medical librarians, how MLA developed as an organization as a reflection of the growth of medical libraries, and the presidents' predictions and advice about the future. Results MLA presidents came from varied backgrounds and locales. As MLA grew from a small, intimate group into a multifaceted organization with a professional management staff, the workload of the presidents changed in scope. One recurring theme in the presidential oral histories was the power differential between men and women in the organization and the profession. MLA presidents reminisced about notable annual meetings and praised the positive impact of the organization on members' professional and personal lives. Conclusions The lecture concludes with recommendations to the organization to increase the availability of the oral histories by providing online access for future interviews and to pay careful attention to their long-term preservation.

    About one quarter of the more than 69,000 medical students in this country suffer symptoms of mental illness, including 7% to 18% with substance use disorders. Subjective distress and physical health needs of medical students are also common and have been linked to training stresses. This first large-scale study of medical student health care examined students' physical and mental health concerns and their perceptions of academic vulnerability associated with personal illness. A 7-page, confidential written survey was given to 1,964 students at nine US medical schools in 1996 and 1997. A total of 1,027 students participated (52% response rate). Nearly all (90%) reported needing care for various health concerns, including 47% having at least one mental health or substance-related health issue. A majority of students expressed a preference for health care outside their training institution, largely due to confidentiality concerns, and 90% preferred health insurance allowing off-site care. Students expressed varying levels of concern about academic jeopardy in association with personal illness, with physical health problems such as arthritis causing the least concern and alcohol and drug abuse triggering the most concern. Consistent differences were detected in these views based on respondent's gender, training level, and institution. Most medical students perceive the need for personal health care. Nevertheless, fear of academic reprisal may prevent medical students from seeking necessary care for their health problems during training. This phenomenon may be linked in important but poorly recognized ways to emerging illness and to impairment among medical students and physicians. Women, minority, and clinical students appear more sensitive to the connection between health and academic vulnerability. Constructive implications for medical school curricula, policies, and health care services are discussed. PMID:11154710

    2015-01-01

    Composite materials have seen an increased use in aerospace in recent years and it is expected that this trend will continue due to the benefits of reduced weight, increased strength, and other factors. Ongoing work at NASA involves the investigation of the large-scale use of composites for spacecraft structures (SLS components, Orion Composite Crew Module, etc). NASA is also involved in work to enable the use of composites in advanced aircraft structures through the Advanced Composites Project (ACP). In both areas (space and aeronautics) there is a need for new nondestructive evaluation and materials characterization techniques that are appropriate for characterizing composite materials. This paper will present an overview of NASA's needs for characterizing aerospace composites, including a description of planned and ongoing work under ACP for the detection of composite defects such as fiber waviness, reduced bond strength, delamination damage, and microcracking. The research approaches include investigation of angle array, guided wave, and phase sensitive ultrasonic methods. The use of ultrasonic simulation tools for optimizing and developing methods will also be discussed.

    2014-01-01

    Background Locus of pain control (LPC) is characterized by the behavior of people coping with their health problems, as a result of their own actions (internal control) or external factors or other people (external control). This parameter can be associated with medication adherence, in addition to other psychosocial factors that may also influence this behavior. This study was performed to investigate the influence of the LPC on medication adherence in patients undergoing an orthopedic procedure. Subjects and methods We conducted a prospective cohort study on patients who attended an orthopedic clinic for arthroscopy treatment. The patients’ LPC and pain intensity data were obtained on the day of admission through the use of the LPC scale and the visual analog scale (VAS), respectively, both being validated tools. After arthroscopic surgery, the patients received drug prescriptions and were reassessed after 15 days regarding treatment adherence, using the Morisky test. A P-value <0.05 was considered statistically significant. Results We assessed 79 individuals from both the internal LPC group (n=35) and external LPC group (n=44) and found that there were no group differences in sex, affected limb, cause of injury, repetitive strain injury, duration of pain, or pain intensity. However, there was a higher proportion of patients in the external LPC group that adhered to the prescribed medication compared with the internal LPC group (P<0.01). Conclusion The results showed that among patients who underwent an orthopedic procedure, there was a higher adherence rate to prescribed medication in the external LPC group compared with the internal LPC group.

    Study Objectives: Describe the prevalence of sleep disorders in military personnel referred for polysomnography and identify relationships between demographic characteristics, comorbid diagnoses, and specific sleep disorders. Design: Retrospective cross-sectional study. Setting: Military medical treatment facility. Participants: Active duty military personnel with diagnostic polysomnogram in 2010. Measurements: Primary sleep disorder rendered by review of polysomnogram and medical record by a board certified sleep medicine physician. Demographic characteristics and conditions of posttraumatic stress disorder (PTSD), mild traumatic brain injury (mTBI), anxiety, depression, and pain syndromes determined by medical record review. Results: Primary sleep diagnoses (n = 725) included: mild obstructive sleep apnea (OSA), 207 (27.2%); insomnia, 188 (24.7%); moderate-to-severe OSA, 183 (24.0 %); and paradoxical insomnia,39 (5.1%); behaviorally induced insufficient sleep syndrome, 68 (8.9%) and snoring, 40 (5.3%) comprised our control group. Short sleep duration (< 5 h) was reported by 41.8%. Overall 85.2% had deployed, with 58.1% having one or more comorbid diagnoses. Characteristics associated with moderate-to-severe OSA were age (adjusted odds ratio [OR], 1.03 [95% confidence interval {CI}, 1.0–1.05], sex (male) (adjusted OR, 19.97 [95% CI, 2.66–150.05], anxiety (adjusted OR, 0.58 [95% CI, 0.34–0.99]), and body mass index, BMI (adjusted OR 1.19 [95% CI, 1.13–1.25]; for insomnia, characteristics included PTSD (adjusted OR, 2.12 [95% CI, 1.31–3.44]), pain syndromes (adjusted OR, 1.48 [95%CI, 1.01–2.12]), sex (female) (adjusted OR, 0.22 [95% CI, 0.12–0.41]) and lower BMI (adjusted OR, 0.91 [95% CI, 0.87, 0.95]). Conclusions: Service-related illnesses are prevalent in military personnel who undergo polysomnography with significant associations between PTSD, pain syndromes, and insomnia. Despite having sleep disorders, almost half reported short sleep duration

    The high divorce rate and significant stress experienced by families of academic surgeons stimulated the Committee on Issues of the Association of Academic Surgery to choose medical family stress as the topic for the 1987 Committee presentation at the annual meeting. The Committee hoped to provide insight into the cause of this stress and new strategies for coping with this pervasive problem. Forty-three percent of the 505 surgeons who entered the Association from 1981 through 1984 and 38% of their spouses responded to a questionnaire covering issues of time management, response to stress, child rearing, financial security, and spouse career. A panel consisting of Shirley P. Levine, M.D., Hiram C. Polk, Jr., M.D., and Lane A. Gerber, Ph.D., after discussing the questionnaire results, recommended realistic goal setting, specific prioritization of activities, recognition of the considerable contributions of the spouse, and insight into personal limitations as mechanisms for improving family function.

    Friedreich ataxia is a progressive degenerative disease with neurologic and cardiac involvement. This study characterizes comorbid medical conditions in a large cohort of patients with Friedreich ataxia. Patient diagnoses were collected in a large natural history study of 641 subjects. Prevalence of diagnoses in the cohort with Friedreich ataxia was compared with prevalence in the population without Friedreich ataxia. Ten patients (1.6%) had inflammatory bowel disease, 3.5 times more common in this cohort of individuals with Friedreich ataxia than in the general population. Four subjects were growth hormone deficient, reflecting a prevalence in Friedreich ataxia that is 28 times greater than the general population. The present study identifies specific diagnoses not traditionally associated with Friedreich ataxia that are found at higher frequency in this disease. These associations could represent coincidence, shared genetic background, or potentially interactive disease mechanisms with Friedreich ataxia. PMID:27071470

    Heparin-induced thrombocytopenia (HIT) is an unpredictable, potentially catastrophic adverse effect of heparin treatment resulting from an immune response to platelet factor 4 (PF4)/heparin complexes. No genome-wide evaluations have been performed to identify potential genetic influences on HIT. Here, we performed a genome-wide association study (GWAS) and candidate gene study using HIT cases and controls identified using electronic medical records (EMRs) coupled to a DNA biobank and attempted to replicate GWAS associations in an independent cohort. We subsequently investigated influences of GWAS-associated single nucleotide polymorphisms (SNPs) on PF4/heparin antibodies in non-heparin treated individuals. In a recessive model, we observed significant SNP associations (odds ratio [OR] 18.52; 95% confidence interval [CI] 6.33-54.23; p=3.18×10(-9)) with HIT near the T-Cell Death-Associated Gene 8 (TDAG8). These SNPs are in linkage disequilibrium with a missense TDAG8 SNP. TDAG8 SNPs trended toward an association with HIT in replication analysis (OR 5.71; 0.47-69.22; p=0.17), and the missense SNP was associated with PF4/heparin antibody levels and positive PF4/heparin antibodies in non-heparin treated patients (OR 3.09; 1.14-8.13; p=0.02). In the candidate gene study, SNPs at HLA-DRA were nominally associated with HIT (OR 0.25; 0.15-0.44; p=2.06×10(-6)). Further study of TDAG8 and HLA-DRA SNPs is warranted to assess their influence on the risk of developing HIT. PMID:25503805

    Heparin-induced thrombocytopenia (HIT) is an unpredictable, potentially catastrophic adverse effect of heparin treatment resulting from an immune response to platelet factor 4 (PF4)/heparin complexes. No genome-wide evaluations have been performed to identify potential genetic influences on HIT. Here, we performed a genome-wide association study (GWAS) and candidate gene study using HIT cases and controls identified using electronic medical records (EMRs) coupled to a DNA biobank and attempted to replicate GWAS associations in an independent cohort. We subsequently investigated influences of GWAS-associated single nucleotide polymorphisms (SNPs) on PF4/heparin antibodies in non-heparin treated individuals. In a recessive model, we observed significant SNP associations (OR 18.52 [6.33–54.23], p=3.18×10−9) with HIT near the T-Cell Death-Associated Gene 8 (TDAG8). These SNPs are in linkage disequilibrium with a missense TDAG8 SNP. TDAG8 SNPs trended toward an association with HIT in replication analysis (OR 5.71 [0.47–69.22], p=0.17), and the missense SNP was associated with PF4/heparin antibody levels and positive PF4/heparin antibodies in non-heparin treated patients (OR 3.09 [1.14–8.13], p=0.02). In the candidate gene study, SNPs at HLA-DRA were nominally associated with HIT (OR 0.25 [0.15–0.44], p=2.06×10−6).

    Diagnosing is a knowledge-based skill: to diagnose one must retrieve knowledge from long-term memory and then apply this to a new clinical problem. Prior research on expertise found differences in knowledge structure between experts and novices, and it is assumed that the superior diagnostic performance of experts is somehow related to their superior knowledge structure. Here our objective was to study knowledge structure in final year medical students and to examine the association between knowledge structure and diagnostic performance. Ninety-one students participated. We used concept sorting to assess knowledge structures for four clinical problems. We performed qualitative analysis of knowledge structures, categorizing these as either problem-specific, where knowledge was predominantly structured around concepts specific to that clinical problem, or generic, where knowledge was structured around general concepts that could apply to all clinical problems. We evaluated diagnostic performance using problem-solving questions. Knowledge structure varied between different problems, but for each problem most students had problem-specific knowledge structure. These students had better diagnostic performance than those with generic structure (68.5 vs. 55.3%, d = 0.45, P = 0.004). This difference persisted after adjusting for overall medical knowledge (performance on the Medical Council of Canada Part 1 examination) and clinical problem. We found that most students organize their knowledge around problem-specific concepts, and that this type of knowledge was associated with better diagnostic performance. This may be due to easier knowledge retrieval if there is congruence between how knowledge is stored and how it is applied when diagnosing. PMID:19107567

    OBJECTIVE National hospital performance measures for C. difficile infection (CD) are available; comparing antibacterial use among performance levels can aid in identifying effective antimicrobial stewardship strategies to reduce CDI rates. DESIGN Hospital-level, cross-sectional analysis. METHODS Hospital characteristics (ie, demographics, medications, patient mix) were obtained for 77 hospitals for 2013. Hospitals were assigned 1 of 3 levels of a CDI standardized infection ratio (SIR): 'Worse than,' 'Better than,' or 'No different than' a national benchmark. Analyses compared medication use (total and broad-spectrum antibacterials) for 3 metrics: days of therapy per 1,000 patient days; length of therapy; and proportion of patients receiving a medication across SIR levels. A multivariate, ordered-probit regression identified characteristics associated with SIR categories. RESULTS Regarding total average antimicrobial use per patient, there was a significant difference detected in mean length of therapy: 'No different' hospitals having the longest (4.93 days) versus 'Worse' (4.78 days) and 'Better' (4.43 days) (P<.01). 'Better' hospitals used fewer total antibacterials (693 days of therapy per 1,000 patient days) versus 'No different' (776 days) versus 'Worse' (777 days) (P<.05). The 'Better' hospitals used broad-spectrum antibacterials for a shorter average length of therapy (4.03 days) versus 'No different' (4.51 days) versus 'Worse' (4.38 days) (P<.05). 'Better' hospitals used fewer broad-spectrum antibacterials (310 days of therapy per 1,000 patient days) versus 'No different' (364 days) versus 'Worse' (349 days) (P<.05). Multivariate analysis revealed that the proportion of elderly patients and chemotherapy days of therapy per 1,000 patient days was significantly negatively associated with the SIR. CONCLUSIONS These findings have potential implications regarding the need to fully account for hospital patient mix when carrying out inter-hospital comparisons of

    The Aerospace Mechanisms Symposium (AMS) provides a unique forum for those active in the design, production, and use of aerospace mechanisms. A major focus is the reporting of problems and solutions associated with the development and flight certification of new mechanisms. Organized by the Mechanisms Education Association, the National Aeronautics and Space Administration and Lockheed Martin Space Systems Company (LMSSC) share the responsibility for hosting the AMS. Now in its 36th year, the AMS continues to be well attended, attracting participants from both the United States and abroad. The 36th AMS, hosted by the Glenn Research Center (GRC) in Cleveland, Ohio, was held May 15, 16, and 17, 2002. During these three days, 32 papers were presented. Topics included deployment mechanisms, tribology, actuators, pointing and optical mechanisms, International Space Station mechanisms, release mechanisms, and test equipment. Hardware displays during the supplier exhibit gave attendees an opportunity to meet with developers of current and future mechanism components.

    Exercise-associated hyponatremia (EAH) is defined by a serum or plasma sodium concentration below the normal reference range of 135 mmol/L that occurs during or up to 24 hours after prolonged physical activity. It is reported to occur in individual physical activities or during organized endurance events conducted in austere environments in which medical care is limited and often not available, and patient evacuation to definitive care is often greatly delayed. Rapid recognition and appropriate treatment are essential in the severe form to ensure a positive outcome. Failure in this regard is a recognized cause of event-related fatality. In an effort to produce best practice guidelines for EAH in the austere environment, the Wilderness Medical Society convened an expert panel. The panel was charged with the development of evidence-based guidelines for management of EAH. Recommendations are made regarding the situations when sodium concentration can be assessed in the field and when these values are not known. These recommendations are graded on the basis of the quality of supporting evidence and balance between the benefits and risks/burdens for each parameter according to the methodology stipulated by the American College of Chest Physicians. This is an updated version of the original WMS Practice Guidelines for Treatment of Exercise-Associated Hyponatremia published in Wilderness & Environmental Medicine 2013;24(3):228-240.

    Electronic medical records (EMRs) are being widely implemented for use in genetic and genomic studies. As a phenotypic rich resource, EMRs provide researchers with the opportunity to identify disease cohorts and perform genotype-phenotype association studies. The Epidemiologic Architecture for Genes Linked to Environment (EAGLE) study, as part of the Population Architecture using Genomics and Epidemiology (PAGE) I study, has genotyped more than 15,000 individuals of diverse genetic ancestry in BioVU, the Vanderbilt University Medical Center’s biorepository linked to a de-identified version of the EMR (EAGLE BioVU). Here we develop and deploy an algorithm utilizing data mining techniques to identify primary open-angle glaucoma (POAG) in African Americans from EAGLE BioVU for genetic association studies. The algorithm described here was designed using a combination of diagnostic codes, current procedural terminology billing codes, and free text searches to identify POAG status in situations where gold-standard digital photography cannot be accessed. The case algorithm identified 267 potential POAG subjects but underperformed after manual review with a positive predictive value of 51.6% and an accuracy of 76.3%. The control algorithm identified controls with a negative predictive value of 98.3%. Although the case algorithm requires more downstream manual review for use in large-scale studies, it provides a basis by which to extract a specific clinical subtype of glaucoma from EMRs in the absence of digital photographs.

    As community efforts to reduce the overpopulation and euthanasia of unwanted and unowned cats and dogs have increased, many veterinarians have increasingly focused their clinical efforts on the provision of spay-neuter services. Because of the wide range of geographic and demographic needs, a wide variety of spay-neuter programs have been developed to increase delivery of services to targeted populations of animals, including stationary and mobile clinics, MASH-style operations, shelter services, community cat programs, and services provided through private practitioners. In an effort to promote consistent, high-quality care across the broad range of these programs, the Association of Shelter Veterinarians convened a task force of veterinarians to develop veterinary medical care guidelines for spay-neuter programs. These guidelines consist of recommendations for general patient care and clinical procedures, preoperative care, anesthetic management, surgical procedures, postoperative care, and operations management. They were based on current principles of anesthesiology, critical care medicine, infection control, and surgical practice, as determined from published evidence and expert opinion. They represent acceptable practices that are attainable in spay-neuter programs regardless of location, facility, or type of program. The Association of Shelter Veterinarians envisions that these guidelines will be used by the profession to maintain consistent veterinary medical care in all settings where spay-neuter services are provided and to promote these services as a means of reducing sheltering and euthanasia of cats and dogs.

    In April 2000, the National Academy of Sciences Institute of Medicine (NAS/IOM) Committee on Space Medicine held a workshop under contract with the National Aeronautics and Space Administration (NASA) to explore "innovative terrestrial medical care." There was also a NAS/IOM panel held on "Space Dentistry: Maintaining Astronauts' Oral Health on Long Missions." Air Force Dental Officer Col. Shannon E. Mills chaired the dental committee. Many questions were raised but few answers were available. Prevention was emphasized with the hope that within twenty to thirty years there may be a number of astronaut candidates with no existing dental restorations and with optimum oral health. However, there remains the concern that trauma to teeth could occur within the confines of a zero gravity space capsule as crew members carry out their daily responsibilities. The possibility is evident considering the duration of a space flight to Mars and back could require up to three years. The dental concerns of a space mission are only a small part of a much larger team effort, however, it is one not to be overlooked. An historical review of dentistry's involvement with America's flight and space programs of the 20th Century would be prudent. Many of same questions asked today were addressed in the early days of aviation dentistry as it transitioned into aerospace dentistry. Any past research and experiences would help serve as a foundation to build upon. PMID:12125697

    Context Helicopter emergency medical services and their possible effect on outcomes for traumatically injured patients remain a subject of debate. Because helicopter services are a limited and expensive resource, a methodologically rigorous investigation of its effectiveness compared with ground emergency medical services is warranted. Objective To assess the association between the use of helicopter vs ground services and survival among adults with serious traumatic injuries. Design, Setting, and Participants Retrospective cohort study involving 223 475 patients older than 15 years, having an injury severity score higher than 15, and sustaining blunt or penetrating trauma that required transport to US level I or II trauma centers and whose data were recorded in the 2007–2009 versions of the American College of Surgeons National Trauma Data Bank. Interventions Transport by helicopter or ground emergency services to level I or level II trauma centers. Main Outcome Measures Survival to hospital discharge and discharge disposition. Results A total of 61 909 patients were transported by helicopter and 161 566 patients were transported by ground. Overall, 7813 patients (12.6%) transported by helicopter died compared with 17 775 patients (11%) transported by ground services. Before propensity score matching, patients transported by helicopter to level I and level II trauma centers had higher Injury Severity Scores. In the propensity score–matched multivariable regression model, for patients transported to level I trauma centers, helicopter transport was associated with an improved odds of survival compared with ground transport (odds ratio [OR], 1.16; 95% CI, 1.14–1.17; P<.001; absolute risk reduction [ARR], 1.5%). For patients transported to level II trauma centers, helicopter transport was associated with an improved odds of survival (OR, 1.15; 95% CI, 1.13–1.17; P < .001; ARR, 1.4%). A greater proportion (18.2%) of those transported to level I trauma centers

    Utilization of National Aeronautics and Space Administration (NASA) technology in medicine is discussed. The objective is best obtained by stimulation of the introduction of new or improved commercially available medical products incorporating aerospace technology. A bipolar donor/recipient model of medical technology transfer is presented to provide a basis for the team's methodology. That methodology is designed to: (1) identify medical problems and NASA technology that, in combination, constitute opportunities for successful medical products; (2) obtain the early participation of industry in the transfer process; and (3) obtain acceptance by the medical community of new medical products based on NASA technology. Two commercial transfers were completed: the Stowaway, a lightweight wheelchair that provides mobility for the disabled and elderly in the cabin of commercial aircraft, and Micromed, a portable medication infusion pump for the reliable, continuous infusion of medications such as heparin or insulin. The marketing and manufacturing factors critical to the commercialization of the lightweight walker incorporating composite materials were studied. Progress was made in the development and commercialization of each of the 18 currently active projects.

    Abstract The impact of behavioral functioning on medication adherence in children with perinatally acquired HIV infection is not well-explored, but has important implications for intervention. This report addresses the relationship between behavioral functioning and child self-report or caregiver report of medication adherence among children and adolescents enrolled in Pediatric AIDS Clinical Trials Group Protocol 219C (conducted 2000–2007). A total of 1134 participants, aged 3–17 years, received a behavioral evaluation and adherence assessment. Complete adherence was defined as taking 100% of prescribed antiretroviral medications during three days preceding the study visit. Multivariable logistic regression models were used to evaluate associations between adherence and behavioral functioning, adjusting for potential confounders, including demographic, psychosocial, and health factors. Children demonstrated higher than expected rates of behavioral impairment (≈7% expected with T > 65) in the areas of conduct problems (14%, z = 7.0, p < 0.001), learning problems (22%, z = 12.2, p < 0.001), somatic complaints (22%, z = 12.6, p < 0.001), impulsivity-hyperactivity (20%, z = 11.1, p < 0.001), and hyperactivity (19%, z = 10.6, p < 0.001). Children with behavioral impairment in one or more areas had significantly increased odds of nonadherence [adjusted odds ratio (aOR) = 1.49, p = 0.04]. The odds of nonadherence were significantly higher for those with conduct problems and general hyperactivity (aOR = 2.03, p = 0.005 and aOR = 1.68, p = 0.02, respectively). Psychosocial and health factors, such as recent stressful life events and higher HIV RNA levels, were also associated with nonadherence. Knowledge of behavioral, health, and social influences affecting the child and family should guide the development of appropriate, evidence-based interventions for medication adherence.

    2014-01-01

    Background Many countries have devoted considerable efforts in an attempt to improve the performance of their health care systems. National Medical Associations (NMAs), along with other stakeholders, play a part in the promotion of such activities. The purpose of this paper is to explore the nature and level of participation of NMAs in activities of quality improvement in medicine, with a specific emphasis on Israel. Methods The authors conducted a survey among NMAs around the world inquiring as to their involvement in three central aspects of quality improvement: clinical guidelines, quality measurement and continuing medical education (CME). In addition, they conducted a review of the literature in order to gather more information and complete the data collected in the survey. The findings were processed and analyzed comparatively. Results Most of the NMAs surveyed participate in quality improvement activities at least to some extent. NMAs' main involvement is in the regulation of CME and they are involved to a much lesser extent in the preparation of clinical guidelines and in quality measurement. In Israel, the Israeli Medical Association (IMA) has a dominant role in both the preparation of clinical guidelines and the regulation of CME credits. Discussion It is possible that the expertise maintained by the profession, coupled with the organizational power of the NMA as a union, is viewed as beneficial for regulating educational activities in medicine such as CME. Conversely, the issuing of clinical guidelines is usually regarded as a typical scientific activity, and therefore often rests in the hands of professional medical societies. Quality measurement is regarded as a distinctive administrative tool and is usually found in the province of governments. Based on the typology that we introduced in our previous paper, we discovered that the extent of NMAs’ involvement in quality improvement coincides with the mode of governance of the health care system

    Objective: Reflecting patterns evident in past Janet Doe Lectures, the 2005 address reviews the Medical Library Association's (MLA's) professional development activities from their beginnings after World War II. A group of related but separate activities is traced through the establishment of an integrated professional development program. A further objective is to introduce newer members of MLA to their heritage and to remind others how the association has reached this point in its history. Setting: The lecture provides an overview of the evolution of MLA's professional development program—with emphasis on certification and continuing education in the early years. It further reflects briefly on some of the more recent MLA activities that have greatly impacted professional development and underscores some new initiatives. Analysis: The efforts of a virtual who's who of MLA's membership have been responsible for the convergence of the association's efforts over more than half a century to provide a comprehensive professional development program. As a participant in MLA's professional development activities for more than forty years, the 2005 lecturer provides a personal view of the growth and expansion of the program. Conclusions: Professional development has been a hallmark of MLA for many years. The association's challenge is to continue to develop creative and innovative programs, to continuously review and revise existing programs, and to have the vision and vitality to maintain a viable program that will provide the membership with the knowledge and skills needed to function effectively now and in the future.

    2012-01-01

    Background MEDLINE®/PubMed® currently indexes over 18 million biomedical articles, providing unprecedented opportunities and challenges for text analysis. Using Medical Subject Heading Over-representation Profiles (MeSHOPs), an entity of interest can be robustly summarized, quantitatively identifying associated biomedical terms and predicting novel indirect associations. Methods A procedure is introduced for quantitative comparison of MeSHOPs derived from a group of MEDLINE® articles for a biomedical topic (for example, articles for a specific gene or disease). Similarity scores are computed to compare MeSHOPs of genes and diseases. Results Similarity scores successfully infer novel associations between diseases and genes. The number of papers addressing a gene or disease has a strong influence on predicted associations, revealing an important bias for gene-disease relationship prediction. Predictions derived from comparisons of MeSHOPs achieves a mean 8% AUC improvement in the identification of gene-disease relationships compared to gene-independent baseline properties. Conclusions MeSHOP comparisons are demonstrated to provide predictive capacity for novel relationships between genes and human diseases. We demonstrate the impact of literature bias on the performance of gene-disease prediction methods. MeSHOPs provide a rich source of annotation to facilitate relationship discovery in biomedical informatics. PMID:23021552

    Rapid large-area inspection of composite structures for impact damage and multi-layered aluminum skins for corrosion has been a recognized priority for several years in both military and civil aerospace applications. Approaches to this requirement have followed two clearly different routes: the development of novel large-area inspection systems, and the enhancement of current ultrasonic or eddy-current methods to reduce inspection times. Ultrasonic inspection is possible with standard flaw detection equipment but the addition of a linear ultrasonic array could reduce inspection times considerably. In order to investigate their potential, 9-element and 17-element linear ultrasonic arrays for composites, and 64-element arrays for aluminum skins, have been developed to DERA specifications for use with the ANDSCAN area scanning system. A 5 m{sup 2} composite wing surface has been scanned with a scan resolution of approximately 3 mm in 6 hours. With subsequent software and hardware improvements all four composite wing surfaces (top/bottom, left/right) of a military fighter aircraft can potentially be inspected in less than a day. Array technology has been very widely used in the medical ultrasound field although rarely above 10 MHz, whereas lap-joint inspection requires a pulse center-frequency of 12 to 20 MHz in order to resolve the separate interfaces in the lap joint. A 128 mm-long multi-element array of 5 mmx2 mm ultrasonic elements for use with the ANDSCAN scanning software was produced to a DERA specification by an NDT manufacturer with experience in the medical imaging field. This paper analyses the performance of the transducers that have been produced and evaluates their use in scanning systems of different configurations.

    The NASA Glenn Research Center (GRC) has long been a major contributor to the development and application of energy storage technologies for NASAs missions and programs. NASA GRC has supported technology efforts for the advancement of batteries and fuel cells. The Electrochemistry Branch at NASA GRC continues to play a critical role in the development and application of energy storage technologies, in collaboration with other NASA centers, government agencies, industry and academia. This paper describes the work in batteries and fuel cell technologies at the NASA Glenn Research Center. It covers a number of systems required to ensure that NASAs needs for a wide variety of systems are met. Some of the topics covered are lithium-based batteries, proton exchange membrane (PEM) fuel cells, and nanotechnology activities. With the advances of the past years, we begin the 21st century with new technical challenges and opportunities as we develop enabling technologies for batteries and fuel cells for aerospace applications.

    This is the First Quarterly Report for the newly reconstituted Aerospace Safety Advisory Panel (ASAP). The NASA Administrator rechartered the Panel on November 18,2003, to provide an independent, vigilant, and long-term oversight of NASA's safety policies and programs well beyond Return to Flight of the Space Shuttle. The charter was revised to be consistent with the original intent of Congress in enacting the statute establishing ASAP in 1967 to focus on NASA's safety and quality systems, including industrial and systems safety, risk-management and trend analysis, and the management of these activities.The charter also was revised to provide more timely feedback to NASA by requiring quarterly rather than annual reports, and by requiring ASAP to perform special assessments with immediate feedback to NASA. ASAP was positioned to help institutionalize the safety culture of NASA in the post- Stafford-Covey Return to Flight environment.

    Chest pain is the most common complaint among cocaine users who present to the ED seeking care and many hospital resources are applied to stratify cocaine users in regard to future cardiac morbidity and mortality. Little is known about the longitudinal cardiac and non cardiac medical outcomes of cocaine users who have been stratified to an ED observation period following their ED visit. Objectives to examine one-year cardiac outcomes in a low-intermediate risk sample of patients with cocaine- associated chest pain in an urban ED, as well as to examine ED recidivism one year for cardiac and non-cardiac complaints. Methods Prospective consecutive cohort study of patients (18–60 years) who presented to an urban Level 1 ED with cocaine-associated chest pain and were risk stratified to low-intermediate cardiac risk. Exclusion criteria: EKG suggestive of AMI, elevated serum cardiac markers, history of AMI or CABG, hemodynamic instability, unstable angina. Baseline interviews using validated measures of health functioning, and substance use were conducted during CPOU stay, and 3, 6, and 12 months. ED utilization during the study year was abstracted from medical chart. Zero-Inflated Poisson regression analyses were conducted to predict recurrent ED visits. Results 219 participants (73% participation) were enrolled, 65% returned to the ED post index visit; 23% returned for chest pain, of these 66% had a positive cocaine urine screen. No patient had an AMI within the one year follow up period. Patients with continued cocaine use were more likely to have a recurrent ED visit (p<0.001) but these repeat visits were most often related to musculoskeletal pain (21%), and injury (30%) rather than potential cardiac complaints. Conclusions Patients with cocaine-associated chest pain who are low to intermediate cardiac risk and complete a CPOU protocol have less then 1% rate of MI in the subsequent 12-months. PMID:18824277

    Problem Identification Oral anticancer medication (OAM) use has been steadily increasing, leading to several patient benefits. A notable challenge for nurses is accurate monitoring of patient OAM regimens because nonadherence is associated with poor health outcomes and decreased survival. Currently, no gold standard measure of OAM adherence exists. The authors conducted a systematic review of the association between objective and patient-reported measures of OAM adherence. Literature Search A systematic electronic literature search was conducted using PubMed, EMBASE, Scopus, PsycINFO®, Cochrane Library, Web of Science, and CINAHL® databases through November 2014. Data Evaluation Articles were independently reviewed to determine whether they included an original characterization of the level of association between objective and patient-reported measures of OAM adherence. Synthesis From a total of 11,135 articles retrieved, eight studies met inclusion criteria. Objective adherence was primarily assessed using pill counts or Medication Event Monitoring System (MEMSCap™). Patient-reported adherence was most commonly assessed using study-specific questionnaires. Significant positive correlations were observed between objective and patient-reported adherence across most studies, with three studies reporting higher rates of adherence via patient reporting. Conclusions Despite variation in the OAMs and measures used, patient-reported adherence rates were equal to or higher than objective adherence measures across studies. Social desirability bias may be a concern; however, given the significant concordance observed, using patient-reported methods in future studies of OAM adherence may be justified. Implications for Nursing This review provides evidence to support nursing use of patient-reported measures to accurately monitor OAM adherence and potentially improve the quality of patient–provider communication.

    We analyzed associations of dissatisfaction with sexual life and desire for change in female medical students. Students enrolled in medical schools in North America between February and July 2008 were invited to participate in an internet based survey of sexual function. The principle outcome measure was a single item question on sexual life satisfaction and desire for change. Women who reported dissatisfaction and desire for change were classified as “sexually bothered”. The survey also assessed ethnodemographic factors, student status, sexual history, and depressive symptoms. Respondents completed the Female Sexual Function Index (FSFI) and the Index of Sex Life (ISL). Descriptive statistics, ANOVA, and multivariable logistic regression were utilized to analyze responses. There were 661 non-virgin female subjects with data adequate for analysis. Whereas 281 (43%) of these met criteria for High Risk of Female Sexual Dysfunction (HRFSD) based on FSFI scoring, just 173 (26%) reported sexual bother. Among women with HRFSD, 126 (45%) reported sexual bother; in women without HRFSD, 362 (95%) were not sexually bothered. Interference in sexual life from tiredness and stress were associated with sexual bother. Progressively better scores on the FSFI-desire, orgasm, and satisfaction domains were significantly associated with lower odds of sexual bother. Few women in this cohort with FSFI score >26.55 reported sexual bother. Women with FSFI less than 26.55 had greater odds of sexual bother but this criterion alone was not pathognomonic for sexual concerns. Issues of sexual desire and orgasm appear to play a more important role than lubrication, arousal, and sexual pain issues in this population. PMID:22971616

    Growing evidence suggests that immune dysregulation may be involved in depressive disorders, but the exact nature of this association is still unknown and may be restricted to specific subgroups. This study examines the association between depressive disorders, depression characteristics and antidepressant medication with inflammation in a large cohort of controls and depressed persons, taking possible sex differences and important confounding factors into account. Persons (18-65 years) with a current (N = 1132) or remitted (N = 789) depressive disorder according to DSM-IV criteria and healthy controls (N = 494) were selected from the Netherlands Study of Depression and Anxiety. Assessments included clinical characteristics (severity, duration and age of onset), use of antidepressant medication and inflammatory markers (C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α)). After adjustment for sociodemographics, currently depressed men, but not women, had higher levels of CRP (1.33 versus 0.92 mg l(-1), P<0.001, Cohen's d = 0.32) and IL-6 (0.88 versus 0.72 pg ml(-1), P = 0.01, Cohen's d = 0.23) than non-depressed peers. Associations reduced after considering lifestyle and disease indicators--especially body mass index--but remained significant for CRP. After full adjustment, highest inflammation levels were found in depressed men with an older age of depression onset (CRP, TNF-α). Furthermore, inflammation was increased in men using serotonin-norepinephrine reuptake inhibitors (CRP, IL-6) and in men and women using tri- or tetracyclic antidepressants (CRP), but decreased among men using selective serotonin reuptake inhibitors (IL-6). In conclusion, elevated inflammation was confirmed in depressed men, especially those with a late-onset depression. Specific antidepressants may differ in their effects on inflammation.

    Nanolaminate manufacturing (NLM) is a new way of developing materials whose properties can far exceed those of homogeneous materials. Traditional alloys, composites and bulk laminates tend to average the properties of the materials from which they were made. With nanostructured materials, the high density of interfaces between dissimilar materials results in novel material properties. For example, materials made -from alternating nanoscale layers of metals and oxides have exhibited thermal conductivities far below those of the oxides themselves. Also, metallic nanolaminates can have peak strengths 100 times lager than the bulk constituent metals. Recent work at MSFC has focused on the development of nickel/aluminum oxide (Ni/Al2O3)) nanolaminates. Ni/Al2O3 nanolaminates are expected to have better strength, creep and fatigue resistance, oxygen compatibility, and corrosion resistance than the traditional metal-matrix composites of this material, which has been used in a variety of aerospace applications. A chemical vapor deposition (CW) system has been developed and optimized for the deposition of nanolaminates. Nanolaminates with layer thicknesses between 10 and 300 nm have been successfully grown and characterization has included scanning electron microscopy (SEM) and atomic force microscopy (AFM) Nanolaminates have a large variety of potential applications. They can be tailored to have both very small and anisotropic thermal conductivities and are promising as thermal coatings for both rock$ engine components and aerobraking structures. They also have the potential to be used in aerospace applications where strength at high temperatures, corrosion resistance or resistance to hydrogen embrittlement is important. Both CVD and magnetron sputtering facilities are available for the deposition of nanolayered materials. Characterization equipment includes SEM, AFM, X-ray diffraction, transmission electron microscopy, optical profilometry, and mechanical tensile pull

  14. Conceptual design for aerospace vehicles

    1989-01-01

    The designers of aircraft and more recently, aerospace vehicles have always struggled with the problems of evolving their designs to produce a machine which would perform its assigned task(s) in some optimum fashion. Almost invariably this involved dealing with more variables and constraints than could be handled in any computationally feasible way. With the advent of the electronic digital computer, the possibilities for introducing more variable and constraints into the initial design process led to greater expectations for improvement in vehicle (system) efficiency. The creation of the large scale systems necessary to achieve optimum designs has, for many reason, proved to be difficult. From a technical standpoint, significant problems arise in the development of satisfactory algorithms for processing of data from the various technical disciplines in a way that would be compatible with the complex optimization function. Also, the creation of effective optimization routines for multi-variable and constraint situations which could lead to consistent results has lagged. The current capability for carrying out the conceptual design of an aircraft on an interdisciplinary bases was evaluated to determine the need for extending this capability, and if necessary, to recommend means by which this could be carried out. Based on a review of available documentation and individual consultations, it appears that there is extensive interest at Langley Research Center as well as in the aerospace community in providing a higher level of capability that meets the technical challenges. By implication, the current design capability is inadequate and it does not operate in a way that allows the various technical disciplines to participate and cooperately interact in the design process. Based on this assessment, it was concluded that substantial effort should be devoted to developing a computer-based conceptual design system that would provide the capability needed for the near

    2013-01-01

    Background In many countries, NMAs, along with other stakeholders, play a part in the regulation of physicians. The purpose of this paper is to compare and explain the level of involvement of NMAs in physician regulation in several developed countries, with a specific emphasis on Israel. Methods The authors conducted a review of the literature on physician regulation, focusing on licensing and registration, postgraduate training and physician disciplinary measures. Detailed country specific information was also obtained via the websites of relevant NMAs and regulatory bodies and correspondence with select NMAs. Five test cases were examined in detail: Germany, Israel, the Netherlands, the United Kingdom and the United States. The Israeli case will be discussed at greater length. Results Medical licensing usually lies in the hands of the government (on the national or state level). Specialist training, on the other hand, is often self-regulated and entrusted in the hands of the profession, frequently under the direct responsibility of the NMA, as in Israel, the Netherlands and Germany. In all the countries presented, other than Germany, the NMA is not involved in instituting disciplinary procedures in cases of alleged physician misconduct. Discussion The extent to which NMAs fulfill regulatory functions varies greatly from country to country. The relationship between government and the profession in the area of regulation often parallels the dominant mode of governance in the health care system as a whole. Specifically, the level of involvement of the Israeli Medical Association in medical regulation is a result of political, historical and ideological arrangements shaped vis-à-vis the government over the years. Conclusions In Continental Europe, co-operation between the NMA and the government is more common than in the USA and the UK. The Israeli regulatory model emerged in a European-like fashion, closer to the Netherlands than to Germany. The Israeli case, as

    Background: In spite of the progress made in the treatment of psychiatric disorders during the last few decades, nonadherence continues to be a frequent phenomenon, often associated with potentially severe clinical consequences and increased health-care costs. There are numerous factors associated with medication nonadherence in patients with mental illness. The aim of the study was to determine the incidence and factors associated with medication nonadherence among psychiatric outpatients. Materials and Methods: A cross-sectional study was carried out in the outpatient psychiatric department of an Indian tertiary care private hospital over a period of 1 year. Patients aged 18 years and above who presented with mental illness as diagnosed by the International Classification of Diseases (ICD)-10 and who were receiving at least one psychotropic medication for at least 1 month were included in the study. Medication adherence was assessed using the Medication Adherence Rating Scale (MARS). Results: Of the 400 patients, 172 (43%) were nonadherent to their prescribed medications. There is a statistically significant association between the education (P = 0.001), number of drugs (P = 0.002), family income (P = 0.013), and nonadherence. Among the 172 patients, 33.5 % were nonadherent to their therapy due to patient-related factors followed by drug-related factors (32%) and disease-related factors (31%). Conclusion: The overall incidence of medication nonadherence in patients with mental illness was 43%. Numerous factors contributed to medication nonadherence. Strategies need to be developed and implemented to enhance medication adherence, and thereby achieve a better therapeutic outcome in patients with mental illness. PMID:26440396

    As efforts to reduce the overpopulation and euthanasia of unwanted and unowned dogs and cats have increased, greater attention has been focused on spay-neuter programs throughout the United States. Because of the wide range of geographic and demographic needs, a wide variety of programs have been developed to increase delivery of spay-neuter services to targeted populations of animals, including stationary and mobile clinics, MASH-style operations, shelter services, feral cat programs, and services provided through private practitioners. In an effort to ensure a consistent level of care, the Association of Shelter Veterinarians convened a task force of veterinarians to develop veterinary medical care guidelines for spay-neuter programs. The guidelines consist of recommendations for preoperative care (eg, patient transport and housing, patient selection, client communication, record keeping, and medical considerations), anesthetic management (eg, equipment, monitoring, perioperative considerations, anesthetic protocols, and emergency preparedness), surgical care (eg, operating-area environment; surgical-pack preparation; patient preparation; surgeon preparation; surgical procedures for pediatric, juvenile, and adult patients; and identification of neutered animals), and postoperative care (eg, analgesia, recovery, and release). These guidelines are based on current principles of anesthesiology, critical care medicine, microbiology, and surgical practice, as determined from published evidence and expert opinion. They represent acceptable practices that are attainable in spay-neuter programs. PMID:18593314

    Exercise-associated hyponatremia (EAH) typically occurs during or up to 24 hours after prolonged physical activity, and is defined by a serum or plasma sodium concentration below the normal reference range of 135 mEq/L. It is also reported to occur in individual physical activities or during organized endurance events conducted in austere environments in which medical care is limited or often not available, and patient evacuation to definitive care is often greatly delayed. Rapid recognition and appropriate treatment are essential in the severe form to ensure a positive outcome. Failure in this regard is a recognized cause of event-related fatality. In an effort to produce best practice guidelines for EAH in the austere environment, the Wilderness Medical Society convened an expert panel. The panel was charged with the development of evidence-based guidelines for management of EAH. Recommendations are made regarding the situations when sodium concentration can be assessed in the field and when these values are not known. These recommendations are graded based on the quality of supporting evidence and balance between the benefits and risks/burdens for each parameter according to the methodology stipulated by the American College of Chest Physicians.

    2012-06-01

    Physicians have an ethical duty to keep up-to-date with current knowledge. Professional medical associations such as the European Society of Cardiology (ESC) support these obligations. In Europe, the costs of continuing medical education (CME) are insufficiently supported from governments and employers; however, medical associations have been criticized for accepting alternative financial support from industry. Medical education and training in research include learning how to assess the quality and reliability of any information. There is some risk of bias in any form of scientific communication including intellectual, professional, and financial and it is essential that in particular, the latter must be acknowledged by full disclosure. It is essential that there is strong collaboration between basic and clinical researchers from academic institutions on the one hand, with engineers and scientists from the research divisions of device and pharmaceutical companies on the other. This is vital so that new diagnostic methods and treatments are developed. Promotion of advances by industry may accelerate their implementation into clinical practice. Universities now frequently exhort their academic staff to protect their intellectual property or commercialize their research. Thus, it is not commercial activity or links per se that have become the target for criticism but the perceived influence of commercial enterprises on clinical decision-making or on messages conveyed by professional medical organizations. This document offers the perspective of the ESC on the current debate, and it recommends how to minimize bias in scientific communications and CME and how to ensure proper ethical standards and transparency in relations between the medical profession and industry.

    Approximately 10% of US college students are engaged in non-medical use of prescription stimulants (NMUPS) and that use is linked to concerning health, educational, and societal consequences. Few studies have assessed normative perceptions surrounding NMUPS. Accordingly, we examined self-reported use and normative perceptions for NMUPS and demographic factors that may be associated with them. We also investigated whether higher normative perceptions for NMUPS were related to the most commonly used and abused substance among college students (alcohol). METHOD 1106 undergraduates participated in an online survey of normative perceptions of NMUPS and students’ own drinking and stimulant use habits. RESULTS Students overestimated NMUPS by other students and those normative estimates were associated with higher NMUPS. Living in a fraternity or sorority was related to higher NMUPS and perceived norms. Finally, higher normative perceptions of NMUPS were associated with higher hazardous drinking. CONCLUSION The large discrepancy between actual use (generally low) and students’ perceptions (generally high), and the relationship of these perceptions to both one’s own use of NMUPS and alcohol suggests that interventions aimed at correcting norms may be useful.

    Pattern recognition and classification are two of the key topics in computer science. In this paper a novel method for the task of pattern classification is presented. The proposed method combines a hybrid associative classifier (Clasificador Híbrido Asociativo con Traslación, CHAT, in Spanish), a coding technique for output patterns called one-hot vector and majority voting during the classification step. The method is termed as CHAT One-Hot Majority (CHAT-OHM). The performance of the method is validated by comparing the accuracy of CHAT-OHM with other well-known classification algorithms. During the experimental phase, the classifier was applied to four datasets related to the medical field. The results also show that the proposed method outperforms the original CHAT classification accuracy. PMID:24752287

    2007-01-01

    Parkinson's disease is a neurodegenerative disorder that affects approximately 1% of people over the age of 60 years. Levodopa is standard, and often initial, therapy for patients with this condition; however, with continued treatment and as the disease progresses, up to 80% of patients experience 'wearing-off' symptoms, dyskinesias and other motor complications. These levodopa-associated problems may become disabling and profoundly affect quality of life. Medications commonly used to manage these symptoms include monoamine oxidase type B (MAO-B) inhibitors, catechol-O-methyltransferase (COMT) inhibitors, the NMDA receptor antagonist amantadine and dopamine receptor agonists. Agents that block MAO-B, such as rasagiline and selegiline, are used as both initial and adjunctive therapy in patients with Parkinson's disease. These medications increase concentrations of dopamine in the brain by blocking its reuptake from the synaptic cleft, a mechanism that can slow motor decline, increase 'on' time and improve symptoms of Parkinson's disease. Adverse events with these agents can include confusion, hallucination and orthostatic hypotension. MAO-B inhibition may elicit drug-drug interactions if administered with TCAs, SSRIs or SNRIs. Conventional oral selegiline is associated with potentially harmful plasma concentrations of three major amphetamine metabolites, although metabolite concentrations are significantly lower with a new orally disintegrating tablet (ODT) selegiline formulation. Selegiline ODT is also absorbed more efficiently and shows less pharmacokinetic variability than conventional oral selegiline.COMT mediates peripheral catabolism of levodopa. Therefore, agents that block COMT, such as tolcapone and entacapone, increase the elimination half-life of levodopa. Given adjunctively with levodopa, COMT inhibitors can decrease 'off' time and increase 'on' time, as well as lower the daily levodopa dose. Although more potent than entacapone, tolcapone requires

    Introduction The selection of a medical specialty has been associated with multiple factors, such as personal preferences, academic exposure, motivational factors and sociodemographic factors, such as gender. The number of women in the medical field has increased in recent years. In Latin America, we have not found any studies that explore this relationship. Objective To determine whether there is an association between gender and the intention to choose a medical specialty in medical students from 11 countries in Latin America. Methods Secondary analysis of the Collaborative Working Group for the Research of Human Resources for Health (Red-LIRHUS) data; a multi-country project of students in their first year and fifth year of study, from 63 medical schools in 11 Latin American countries. All students who referred intention to choose a certain medical specialty were considered as participants. Results Of the 11073 surveyed students, 9235 indicated the name of a specific specialty. The specialties chosen most often in the fifth year were General Surgery (13.0%), Pediatrics (11.0%), Internal Medicine (10.3%) and Obstetrics/Gynecology (9.0%). For women, the top choices were Pediatrics (15.8%), Obstetrics/Gynecology (11.0%), Cardiology (8.7%), General Surgery (8.6%), and Oncology (6.4%). In the adjusted analysis, the female gender was associated with the choice of Obstetrics/Gynecology (RP: 2.75; IC95%: 2.24–3.39); Pediatric Surgery (RP: 2.19; IC95%: 1.19–4.00), Dermatology (RP: 1.91; IC95%:1.24–2.93), Pediatrics (RP: 1.83; IC95%: 1.56–2.17), and Oncology (RP: 1.37; IC95%: 1.10–1.71). Conclusions There is an association between the female gender and the intention to choose Obstetrics/Gynecology, Pediatrics, Pediatric Surgery, Dermatology, and Oncology. We recommend conducting studies that consider other factors that can influence the choice of a medical specialty. PMID:27519055

    Introduction Smoking is the leading cause of lung cancer around the world. In a developing country like Pakistan with low levels of literacy and general awareness about adverse effects of smoking, doctors play a pivotal role in educating the masses about its harmful consequences and providing support for smoking cessation. However, their efficacy is affected if they smoke themselves, and oftentimes the habits cultivated during educational recourse are carried into the professional careers. The aim of this study was to document the prevalence of smoking among final year medical students of Lahore, Pakistan, and the factors associated with it. Methodology Study approval was obtained from Combined Military Hospital (CMH) Lahore Medical College, Ethics Review Committee. A cross-sectional survey was carried out in four medical colleges and hospitals of Lahore, Pakistan. A questionnaire consisting of 14 questions related to basic demographics and smoking was used after being pilot tested on 20 students of CMH. The overall response rate was 74.89%. Data was collected from 337 respondents, of which 38 forms were discarded and 299 forms were analyzed by SPSS V21. Results Among the 299 respondents, there were 128 males (42.81%) and 171 females (57.19%) with 32 (10.70%) smokers. Male students reported smoking (n = 27, 21.09%) more than their female counterparts (n = 5, 0.02%). The mean age of participants was 23.01 years. Students having an active smoker at home had statistically significant positive correlations with current smoking status and the number of cigarettes smoked per day. Students with household smoking contacts were also more likely to smoke if they belonged to the male gender. Conclusion Prevalence of smoking in medical students is lower than in the general population but still considerable in the male students. There is a need to target this particular population with interactive counseling sessions, education campaigns, and anti-smoking rules to decrease

  10. Wear Characteristics of Oleophobic Coatings in Aerospace Applications

    NASA Astrophysics Data System (ADS)

    Shams, Hamza; Siddiqui, Bilal A.; Saleem, Sajid

    This paper investigates the wear characteristics of oleophobic coatings when applied over Inconel 718, which has widespread applications in the aerospace industry. Coatings once applied were selectively exposed to controlled uni-and then multi-directional stand storm conditions. Size and speed of sand particles colliding with the work surface were carefully moderated to simulate sand storm conditions. Study of friction was performed using Lateral Force Microscopy (LFM) coupled with standard optical microscopy. The analysis has been used to devise a coefficient of friction value and in turn suggest wear behavior of the coated surface including the time associated with exposure of the base substrate. The analysis after validation aims to suggest methods for safe usage of these coatings for aerospace applications.

    The ecological diversity of the periodontal microenvironment may provide suitable conditions for the colonization of species not usually considered members of the oral microbiota. In this investigation, we aimed to determine the prevalence and levels of pathogenic species of medical relevance in the microbiota of individuals with distinct periodontal clinical status. Subgingival biofilm was obtained from patients with periodontal health (H, n = 81), gingivitis (G, n = 55), generalized aggressive (AgP, n = 36) or chronic periodontitis (CP, n = 98), and analyzed for 39 microbial taxa using a checkerboard DNA-DNA hybridization technique. Microbial differences among groups, as well as associations between clinical and microbiological parameters were sought by non-parametric and univariate correlation tests. Neisseria spp., Peptostreptococus anaerobius, Candida albicans, enterobacteria, Pseudomonas aeruginosa, Eubacterium saphenum, Clostridium difficile and Olsenella uli were detected in high mean prevalence and counts in the subgingival microbiota of the study population. Species that were more related to periodontal inflammation and tissue destruction at the patient and site levels included enterobacteria, C. albicans, Neisseria spp., P. aeruginosa, O. uli, Hafnia alvei, Serratia marcescens and Filifactor alocis (p < 0.05). In contrast, Fusobacterium necrophorum, Lactobacillus acidophilus, Staphylococcus aureus and Streptococcus pneumoniae were associated with periodontal health (p < 0.05). Pathogenic species of medical importance may be detected in high prevalence and levels in the periodontal microbiota. Regardless of their role in periodontal health or disease, the periodontal biofilm may be a source for dissemination and development of systemic infections by these pathogenic microorganisms.

    The number of medical students entering primary care residencies continues to decrease. The association between student attitudes toward underserved populations and residency choice has received little attention even though primary care physicians see a larger proportion of underserved patients than most other specialists. We evaluated attitudes toward underserved populations in 826 medical students using a standardized survey, and used logistic regression to assess the effect of attitudes, along with other variables, on selection of a primary care residency. We compared results between two groups defined by year of entry to medical school (1993-99 and 2000-05) to determine whether associations differed by time period. Students' attitudes regarding professional responsibility toward underserved populations remained high over the study period; however, there was a statistically. significant association between positive attitudes and primary care residency in the early cohort only. This association was not found in the more recent group. PMID:20453348

    Objectives. This study collected and evaluated data on the costs of outpatient medical care and family burden associated with osteoporosis-related fracture rehabilitation following hospital discharge in China. Materials and Methods. Data were collected using a patient questionnaire from osteoporosis-related fracture patients (N = 123) who aged 50 years and older who were discharged between January 2011 and January 2013 from 3 large hospitals in China. The survey captured posthospital discharge direct medical costs, indirect medical costs, lost work time for caregivers, and patient ambulatory status. Results. Hip fracture was the most frequent fracture site (62.6%), followed by vertebral fracture (34.2%). The mean direct medical care costs per patient totaled 3,910¥, while mean indirect medical costs totaled 743¥. Lost work time for unpaid family caregivers was 16.4 days, resulting in an average lost income of 3,233¥. The average posthospital direct medical cost, indirect medical cost, and caregiver lost income associated with a fracture patient totaled 7,886¥. Patients' ambulatory status was negatively impacted following fracture. Conclusions. Significant time and cost of care are placed on patients and caregivers during rehabilitation after discharge for osteoporotic fracture. It is important to evaluate the role and responsibility for creating the growing and inequitable burden placed on patients and caregivers following osteoporotic fracture. PMID:26221563

    It now appears likely that commercial entities will carry paying passengers on suborbital spaceflights in this decade. The stresses of spaceflight, the effects of microgravity, and the limited capability for medical care onboard make it advisable to develop a system of medical clearance for such space tourists. The Aerospace Medical Association, therefore, organized a Space Passenger Task Force whose first report on medical guidelines was published in 2001. That report consisted of a list of conditions that would disqualify potential passengers for relatively long orbital flights. The Task Force reconvened in 2002 to focus on less stringent medical screening appropriate for short duration suborbital flights. It was assumed that such commercial flights would involve: 1) small spacecraft carrying 4-6 passengers; 2) a cabin maintained at sea-level "shirt-sleeve" condition; 3) maximum accelerations of 2.0-4.5 G; 4) about 30 min in microgravity. The Task Force addressed specific medical problems, including space motion sickness, pregnancy, and medical conditions involving the risk of sudden incapacitation. The Task Force concluded that a medical history should be taken from potential passengers with individualized follow-up that focuses on areas of concern. PMID:12433241

    Medication-related osteonecrosis of the jaw (MRONJ) represents a complication of bisphosphonate treatment that responds poorly to standard treatment. In a retrospective cohort study we investigated a possible role of Actinomyces spp. in the pathogenesis of MRONJ. Deep biopsies of necrotic bone were collected during surgical treatment of MRONJ and evaluated by histology and microbiology for the presence of Actinomyces spp. Microbiological, demographic and clinicpathological data were analyzed for risk of Actinomyces-associated MRONJ. Between 2005 and 2014, 111 patients suffering from histologically-confirmed MRONJ were identified. Actinomyces spp. were detected in 99 cases (89%) by histology and in six further patients by microbiological culture. A diverse microbial flora was found in all specimens without association with Actinomyces spp. Demographic and clinicopathological characteristics did not separate significantly Actinomyces-positive from Actinomyces-negative cases. Our observations confirm previous reports of a high prevalence of Actinomyces spp. in MRONJ in the single largest cohort available up to now. The high prevalence of Actinomyces spp. and the lack of clinicopathological risk factors underline the prominent role of Actinomyces spp. in MRONJ and may change the current understanding of MRONJ. Established prolonged antimicrobial treatment regimens against Actinomyces spp. infection could therefore be a mainstay of future MRONJ management. PMID:27530150

    Purpose. To report a case of orbital myositis associated with Coxsackie virus and its medical and surgical approach. Methods. Complete ophthalmological examination and imaging and analytical investigation were performed. Results. A 6-year-old male presented with subacute painless binocular horizontal diplopia. Examination revealed bilateral best-corrected visual acuity (BCVA) of 20/20 and right eye 45-prism-dioptre (PD) esotropia in near and distance fixations, with no motility restrictions. Serologic screening was positive for Coxsackie virus acute infection and computerized tomography (CT) suggested right eye medial rectus orbital myositis. An oral corticosteroid 1.0 mg/kg/day regimen was started. A new CT after two months showed symmetrical lesions in both medial rectus muscles. Corticosteroids were increased to 1.5 mg/kg/day. After imagiological resolution on the 4th month, alternating 45 PD esotropia persisted. Bilateral 7 mm medial rectus recession was performed after 1 year without spontaneous recovery. At 1-year follow-up, the patient is orthophoric with 200′′ stereopsis and bilateral 20/20 BCVA. Conclusions. To our knowledge, this is the first reported case of orbital myositis associated with Coxsackie virus. This is also the first reported case of isolated strabismus surgery after orbital myositis in pediatric age, highlighting the favourable aesthetic and functional outcomes even in cases of late ocular motility disorders.

    Background and objectives Relevant heterogeneity exists among Postgraduate Schools in Medical Oncology, also within the same country. In order to provide a comprehensive overview of the landscape of Italian Postgraduate Schools in Medical Oncology, the Italian Association of Medical Oncology (AIOM) undertook an online survey, inviting all the residents to describe their daily activities and to express their overall satisfaction about their programs. Methods A team composed of five residents and three consultants in medical oncology prepared a 38 items questionnaire that was published online in a reserved section, accessible through a link sent by e-mail. Residents were invited to anonymously fill in the questionnaire that included the following sub-sections: quality of teaching, clinical and research activity, overall satisfaction. Results Three-hundred and eleven (57%) out of 547 invited residents filled in the questionnaire. Two-hundred and twenty-three (72%) participants declared that attending lessons was frequently difficult and 153 (49%) declared they did not gain substantial improvement in their knowledge from them. Fifty-five percent stated that they did not receive lessons on palliative care. Their overall judgment about didactic activity was low in 63% of the interviewed. The satisfaction for clinical activity was in 86% of cases good: 84% recognized that, during the training period, they acquired a progressive independence on patients' management. About research activity, the majority (79%) of participants in the survey was actively engaged in managing patients included in clinical trials but the satisfaction level for the involvement in research activities was quite low (54%). Overall, 246 residents (79%) gave a positive global judgment of their Medical Oncology Schools. Conclusions The landscape of Italian Postgraduate Schools in Medical Oncology is quite heterogeneous across the country. Some improvements in the organization of teaching and in the

    New advances in the reinforcement of polymer matrix composite materials are critical for advancement of the aerospace industry. Reinforcements are required to have good mechanical and thermal properties, large aspect ratio, excellent adhesion to the matrix, and cost effectiveness. To fulfill the requirements, nanocomposites in which the matrix is filled with nanoscopic reinforcing phases having dimensions typically in the range of 1nm to 100 nm show considerably higher strength and modulus with far lower reinforcement content than their conventional counterparts. Graphite is a layered material whose layers have dimensions in the nanometer range and are held together by weak Van der Waals forces. Once these layers are exfoliated and dispersed in a polymer matrix as nano platelets, they have large aspect ratios. Graphite has an elastic modulus that is equal to the stiffest carbon fiber and 10-15 times that of other inorganic reinforcements, and it is also electrically and thermally conductive. If the appropriate surface treatment can be found for graphite, its exfoliation and dispersion in a polymer matrix will result in a composite with excellent mechanical properties, superior thermal stability, and very good electrical and thermal properties at very low reinforcement loadings.

    A systematic design-oriented, five-step approach to material selection is described: 1) establishing design requirements, 2) material screening, 3) ranking, 4) researching specific candidates and 5) applying specific cultural constraints to the selection process. At the core of this approach is the definition performance indices (i.e., particular combinations of material properties that embody the performance of a given component) in conjunction with material property charts. These material selection charts, which plot one property against another, are introduced and shown to provide a powerful graphical environment wherein one can apply and analyze quantitative selection criteria, such as those captured in performance indices, and make trade-offs between conflicting objectives. Finding a material with a high value of these indices maximizes the performance of the component. Two specific examples pertaining to aerospace (engine blades and pressure vessels) are examined, both at room temperature and elevated temperature (where time-dependent effects are important) to demonstrate the methodology. The discussion then turns to engineered/hybrid materials and how these can be effectively tailored to fill in holes in the material property space, so as to enable innovation and increases in performance as compared to monolithic materials. Finally, a brief discussion is presented on managing the data needed for materials selection, including collection, analysis, deployment, and maintenance issues.

    Utilization of NASA technology and its application to medicine is discussed. The introduction of new or improved commercially available medical products and incorporation of aerospace technology is outlined. A biopolar donor-recipient model of medical technology transfer is presented to provide a basis for the methodology. The methodology is designed to: (1) identify medical problems and NASA technology that, in combination, constitute opportunities for successful medical products; (2) obtain the early participation of industry in the transfer process; and (3) obtain acceptance by the medical community of new medical products based on NASA technology. Two commercial transfers were completed: the ocular screening device, a system for quick detection of vision problems in preschool children, and Porta-Fib III, a hospital monitoring unit. Two institutional transfers were completed: implant materials testing, the application of NASA fracture control technology to improve reliability of metallic prostheses, and incinerator monitoring, a quadrupole mass spectrometer to monitor combustion products of municipal incinerators. Mobility aids for the blind and ultrasound diagnosis of burn depth are also studied.

    To reduce costs and improve clinical relevance of genetic studies, there has been increasing interest in performing such studies in hospital-based cohorts by linking phenotypes extracted from electronic medical records (EMRs) to genotypes assessed in routinely collected medical samples. A fundamental difficulty in implementing such studies is extracting accurate information about disease outcomes and important clinical covariates from large numbers of EMRs. Recently, numerous algorithms have been developed to infer phenotypes by combining information from multiple structured and unstructured variables extracted from EMRs. Although these algorithms are quite accurate, they typically do not provide perfect classification due to the difficulty in inferring meaning from the text. Some algorithms can produce for each patient a probability that the patient is a disease case. This probability can be thresholded to define case-control status, and this estimated case-control status has been used to replicate known genetic associations in EMR-based studies. However, using the estimated disease status in place of true disease status results in outcome misclassification, which can diminish test power and bias odds ratio estimates. We propose to instead directly model the algorithm-derived probability of being a case. We demonstrate how our approach improves test power and effect estimation in simulation studies, and we describe its performance in a study of rheumatoid arthritis. Our work provides an easily implemented solution to a major practical challenge that arises in the use of EMR data, which can facilitate the use of EMR infrastructure for more powerful, cost-effective, and diverse genetic studies.

    On March 11, 2011, a gigantic earthquake struck eastern Japan. Utilities such as electricity, water, gas and telecommunication were interrupted. In Koriyama, the City Hall collapsed and government administration offices had to be moved to a nearby baseball stadium that had been designed to include facilities for use during a pandemic. An operations center was set up in this stadium. As members of the Koriyama Medical Association, we following the disaster protocol and set up our operations center in the Koriyama Medical Care Hospital. One large hospital with 280 inpatients and another hospital with 150 inpatients had been heavily damaged. Transfer of those patients to other hospitals without the use of telecommunications was extremely difficult. Many doctors in member hospitals and clinics went out of their way to cooperate throughout the crisis. Up to 5,000 people from the radiation evacuation zone were rushed to Koriyama. They stayed in schools and community centers, where we provided them with healthcare. Even in Koriyama, which is 60 km away from the Fukushima nuclear power plant, radiation levels were high, especially for the first few weeks. Citizens were advised to stay at home and keep their doors and windows closed. These drastic measures and frequent earthquake aftershocks were very stressful, especially for children. To help prevent children from developing posttraumatic stress disorder (PTSD), a project team composed of various groups caring for children was developed, and this team took action to protect children. Through these efforts we hoped to provide children with an appropriate environment to grow normally, even in a zone of persistent low-level radiation. We demonstrated once again that our members' long history of mutual assistance and cooperation with the administration was the main cornerstone to overcome the crisis. PMID:22410536

    An emblem represents the identity of an organization. Through the emblem of an organization, they differentiate the members from others and reinforce the membership, homogeneity, and pride. It is also a tool that an organization officially publicizes its mission and values. The symbol designed by Cho, Byungduk was announced as the first emblem of Korean Medical Association (KMA) on October 31st 1947. His design work has the caduceus with the Taeguk sign on the top, the symbol of Korea, and the Red Cross in the background including the name, 'KMA'. Since then, the emblem was revised three times: in 1964, 1973, and 1995. The current symbol is based on the design of the first one. Although Asklepian, the single serpent-entwined staff of Asklepios, is the one known as the symbol of medicine, this emblem takes the caduceus of Hermes who is the patron god of merchants, thieves, and travelers. The mistake comes from the unawareness of the distinction between the caduceus of Asklepios and Hermes. Moreover, it proves that U. S. Army Medical Corps (USAMC) heavily influenced the reconstruction of Korean health care system including KMA. The USAMC has used the symbol of caduceus since 1902. In 1947, the year that the first emblem of KMA was established, Southern part of Korea was governed by the United States Military Government (USMG, 1945-1948). The current emblem of KMA brings up a question whether we should continue to use the symbol that was taken from USMAC in the historical period of USMG governance. Celebrating 100th anniversary year of KMA, KMA needs to re-evaluate the appropriateness of the KMA symbol. PMID:18175460

    Introduction Voluntary Medical Male Circumcision (VMMC) is the surgical removal of the foreskin by a trained health worker. VMMC was introduced in Zimbabwe in 2009. It is of concern that the programme performance has been below expectations nationally and in Mazowe district. Zimbabwe is unlikely to meet its 2015 target of circumcising 1 200 000 men aged between 15 and 29 years and unlikely to enjoy maximum benefits of VMMC which include prevention of HIV, sexually transmitted infections and cervical cancer. We therefore broadly aimed at identifying factors influencing the level of VMMC uptake in Mazowe district. Methods An analytic cross-sectional study was carried out in Mazowe district. A multi-stage probability sampling strategy was used to select 300 men aged between 18 and 49 years. Pretested interviewer administered questionnaires, key informant interviews and focus group discussions were used to collect data. Quantitative data was analysed using Epi info where odds ratios and p-values were calculated. Qualitative data was analysed thematically. Results Being of Shona origin (AOR= 7.69 (95%CI 1.78-33.20)), fear of pain (AOR= 7.09 (95%CI 2.58-19.47)) and fear of poor wound healing (AOR= 2.68 (95%CI 1.01-7.08)) were independently associated with being uncircumcised while having a circumcised friend and encouragement by a friend or relative were independently associated with being circumcised. Conclusion Fear of pain, fear of poor wound healing and encouragement by a friend or relative were associated with circumcision status. Widening use of surgical devices and third part referrals may assist in scaling up the programme. PMID:25918577

    Visual acuity is a major parameter for quality of vision and quality of life. Information on visual acuity and its associated factors in rural societies almost untouched by any industrialization is mostly non-available. It was, therefore, the purpose of our study to determine the distribution of visual acuity and its associated factors in a rural population not marked influenced by modern lifestyle. The population-based Central India Eye and Medical Study included 4711 subjects (aged 30+ years), who underwent a detailed ophthalmologic examination including visual acuity measurement. Visual acuity measurements were available for 4706 subjects with a mean age of 49.5±13.4 years (range: 30-100 years). BCVA decreased significantly (P<0.001) from the moderately hyperopic group (0.08±0.15 logMAR) to the emmetropic group (0.16±0.52 logMAR), the moderately myopic group (0.28±0.33 logMAR), the highly hyperopic group (0.66±0.62 logMAR) and finally the highly myopic group (1.32±0.92 logMAR). In multivariate analysis, BCVA was significantly associated with the systemic parameters of lower age (P<0.001), higher level of education (P<0.001), higher body stature (P<0.001) and higher body mass index (P<0.001), and with the ophthalmic parameters of more hyperopic refractive error (spherical equivalent) (P<0.001), shorter axial length (P<0.001), lower degree of nuclear cataract (P<0.001), and lower intraocular pressure (P = 0.006). The results suggest that in the rural population of Central India, major determinants of visual acuity were socioeconomic background, body stature and body mass index, age, refractive error, cataract and intraocular pressure.

    significant concern in designing complex systems implementing new technologies is that while knowledge about the system is acquired incrementally, substantial financial commitments, even make-or-break decisions, must be made upfront, essentially in the unknown. One practice that helps in dealing with this dichotomy is the smart embedding of contingencies and margins in the design to serve as buffers against surprises. This issue presents itself in full force in the aerospace industry, where unprecedented systems are formulated and committed to as a matter of routine. As more and more aerospace mission concepts are generated by concurrent design laboratories, it is imperative that such laboratories apply well thought-out contingency and margin structures to their designs. The first part of this publication provides an overview of resource management techniques and standards used in the aerospace industry. That is followed by a thought provoking treatise on margin policies. The expose presents the actual flight telemetry data recorded by the thermal discipline during several recent NASA Goddard Space Flight Center missions. The margins actually achieved in flight are compared against pre-flight predictions, and the appropriateness and the ramifications of having designed with rigid margins to bounding stacked worst case conditions are assessed. The second half of the paper examines the particular issues associated with the application of contingencies and margins in the concurrent engineering environment. In closure, a discipline-by-discipline disclosure of the contingency and margin policies in use at the Integrated Design Center at NASA s Goddard Space Flight Center is made.

    Computational fluid dynamics (CFD) is necessary in the design processes of all current aerospace plane programs. Single-stage-to-orbit (STTO) aerospace planes with air-breathing supersonic combustion are going to be largely designed by means of CFD. The challenge of the aerospace plane design is to provide credible CFD results to work from, to assess the risk associated with the use of those results, and to certify CFD codes that produce credible results. To establish the credibility of CFD results used in design, the following topics are discussed: CFD validation vis-a-vis measurable fluid dynamics (MFD) validation; responsibility for credibility; credibility requirement; and a guide for establishing credibility. Quantification of CFD uncertainties helps to assess success risk and safety risks, and the development of CFD as a design tool requires code certification. This challenge is managed by designing the designers to use CFD effectively, by ensuring quality control, and by balancing the design process. For designing the designers, the following topics are discussed: how CFD design technology is developed; the reasons Japanese companies, by and large, produce goods of higher quality than the U.S. counterparts; teamwork as a new way of doing business; and how ideas, quality, and teaming can be brought together. Quality control for reducing the loss imparted to the society begins with the quality of the CFD results used in the design process, and balancing the design process means using a judicious balance of CFD and MFD.

    Background: Although the frequency of self-medication has been well-documented in the public health literature, but no study has examined the relationship between health literacy and self-medication yet. This study was aimed to investigating the relationship between health literacy and self-medication in a community-based study. Methods: This cross-sectional study was conducted on 924 adults to survey association between health literacy and self-medication among peoples in Ardabil city in 2014 who were selected using a multi-stage random sampling method. Health literacy was measured by the test of functional health literacy in adults and general health status was measured by the 12-item General Health Questionnaire, and self-reported self-medication (overall, sedative, antibiotic and herbal) in last 3 months was assessed. All statistical analysis was performed using the SPSS version 18 and a P < 0.05 was considered significant. Results: The mean age and weight of respondents were 37 years and 74.7 kg, respectively. The prevalence of self-medication was 61.6%, and the percentage of self-administering antibiotics, sedative, and herbal medicines were 40%, 54.4%, and 59.1% in the last 3 months, respectively. Significant relationship was found between of total health literacy and general health status with self-medication. The prevalence of self-medication among participants with poor and very poor self-rated physical and mental health was significantly higher than other participants (P < 0.001). Conclusions: Self-medication had a significant relationship with health literacy and health status. Therefore, the design and implementation of training programs are necessary to increase the perception on the risk of self-medication. PMID:26288710

    Abstract Objective. Emergency medical services (EMS) "superusers" -those who use EMS services at extremely high rates -have not been well characterized. Recent interest in the small group of individuals who account for a disproportionate share of health-care expenditures has led to research on frequent users of emergency departments and other health services, but little research has been done regarding those who use EMS services. To inform policy and intervention implementation, we undertook a descriptive analysis of EMS superusers in a large urban community. In this paper we compare EMS superusers to low, moderate, and high users to characterize factors contributing to EMS use. We also estimate the financial impact of EMS superusers. Methods. We conducted a retrospective cross-sectional study based on 1 year of data from an urban EMS system. Data for all EMS encounters with patients age ≥18 years were extracted from electronic records generated on scene by paramedics. We identified demographic and clinical variables associated with levels of EMS use. EMS users were characterized by the annual number of EMS encounters: low (1), moderate (2-4), high (5-14), and superusers (≥15). In addition, we performed a financial analysis using San Francisco Fire Department (SFFD) 2009 charge and reimbursement data. Results. A total of 31,462 adults generated 43,559 EMS ambulance encounters, which resulted in 39,107 transports (a 90% transport rate). Encounters for general medical reasons were common among moderate and high users and less frequent among superusers and low users, while alcohol use was exponentially correlated with encounter frequency. Superusers were significantly younger than moderate EMS users, and more likely to be male. The superuser group created a significantly higher financial burden/person than any other group, comprising 0.3% of the study population, but over 6% of annual EMS charges and reimbursements. Conclusions. In this retrospective study, adult

    Purpose With a growing need for developing future physician scientists, identifying characteristics of medical students who are likely to benefit from research training programs is important. This study assessed if specific learning styles of medical students, participating in federally funded short-term research training programs, were associated with research self-efficacy, a predictor of research career success. Method Seventy-five first-year medical students from 28 medical schools, selected to participate in two competitive NIH-supported summer programs for research training in aging, completed rating scales to evaluate learning styles at baseline, and research self-efficacy before and after training. We examined associations of individual learning styles (visual-verbal, sequential-global, sensing-intuitive, and active-reflective) with students’ gender, ranking of medical school, and research self-efficacy. Results Research self-efficacy improved significantly following the training programs. Students with a verbal learning style reported significantly greater research self-efficacy at baseline, while visual, sequential, and intuitive learners demonstrated significantly greater increases in research self-efficacy from baseline to post-training. No significant relationships were found between learning styles and students’ gender or ranking of their medical school. Conclusions Assessments of learning styles may provide useful information to guide future training endeavors aimed at developing the next generation of physician-scientists. PMID:25079678

    Background: Ego defense mechanisms are unconscious psychological processes that help an individual to prevent anxiety when exposed to a stressful situation. These mechanisms are important in psychiatric practice to assess an individual’s personality dynamics, psychopathologies, and modes of coping with stressful situations, and hence, to design appropriate individualized treatment. Our study delineates the relationship of ego defense mechanisms with anxiety, depression, and academic performance of Pakistani medical students. Methods: This cross-sectional study was done at CMH Lahore Medical College and Fatima Memorial Hospital Medical and Dental College, both in Lahore, Pakistan, from December 1, 2014 to January 15, 2015. Convenience sampling was used and only students who agreed to take part in this study were included. The questionnaire consisted of three sections: 1) Demographics, documenting demographic data and academic scores on participants’ most recent exams; 2) Hospital Anxiety and Depression Scale (HADS); and 3) Defense Style Questionnaire-40 (DSQ-40). The data were analyzed with SPSS v. 20. Mean scores and frequencies were calculated for demographic variables and ego defense mechanisms. Bivariate correlations, one-way ANOVA, and multiple linear regression were used to identify associations between academic scores, demographics, ego defense mechanisms, anxiety, and depression. Results: A total of 409 medical students participated, of whom 286 (70%) were females and 123 (30%) were males. Mean percentage score on the most recent exams was 75.6% in medical students. Bivariate correlation revealed a direct association between mature and neurotic ego defense mechanisms and academic performance, and an indirect association between immature mechanisms and academic performance. One-way ANOVA showed that moderate levels of anxiety (P < .05) and low levels of depression (P < .05) were associated with higher academic performance. Conclusion: There was a

    This research used survey research to explore and describe the use of computer networks by aerospace engineers. The study population included 2000 randomly selected U.S. aerospace engineers and scientists who subscribed to Aerospace Engineering. A total of 950 usable questionnaires were received by the cutoff date of July 1994. Study results contribute to existing knowledge about both computer network use and the nature of engineering work and communication. We found that 74 percent of mail survey respondents personally used computer networks. Electronic mail, file transfer, and remote login were the most widely used applications. Networks were used less often than face-to-face interactions in performing work tasks, but about equally with reading and telephone conversations, and more often than mail or fax. Network use was associated with a range of technical, organizational, and personal factors: lack of compatibility across systems, cost, inadequate access and training, and unwillingness to embrace new technologies and modes of work appear to discourage network use. The greatest positive impacts from networking appear to be increases in the amount of accurate and timely information available, better exchange of ideas across organizational boundaries, and enhanced work flexibility, efficiency, and quality. Involvement with classified or proprietary data and type of organizational structure did not distinguish network users from nonusers. The findings can be used by people involved in the design and implementation of networks in engineering communities to inform the development of more effective networking systems, services, and policies.

    The use of commercial computer technology in specific aerospace mission applications can reduce the cost and project cycle time required for the development of special-purpose computer systems. Additionally, the pace of technological innovation in the commercial market has made new computer capabilities available for demonstrations and flight tests. Three areas of research and development being explored by the Portable Computer Technology Project at NASA Ames Research Center are the application of commercial client/server network computing solutions to crew support and payload operations, the analysis of requirements for portable computing devices, and testing of wireless data communication links as extensions to the wired network. This paper will present computer architectural solutions to portable workstation design including the use of standard interfaces, advanced flat-panel displays and network configurations incorporating both wired and wireless transmission media. It will describe the design tradeoffs used in selecting high-performance processors and memories, interfaces for communication and peripheral control, and high resolution displays. The packaging issues for safe and reliable operation aboard spacecraft and aircraft are presented. The current status of wireless data links for portable computers is discussed from a system design perspective. An end-to-end data flow model for payload science operations from the experiment flight rack to the principal investigator is analyzed using capabilities provided by the new generation of computer products. A future flight experiment on-board the Russian MIR space station will be described in detail including system configuration and function, the characteristics of the spacecraft operating environment, the flight qualification measures needed for safety review, and the specifications of the computing devices to be used in the experiment.

    Psychiatric symptoms, somatic problems, and co-occurring substance use have been associated with medical marijuana consumption among civilian patients with substance use disorders. It is possible that these factors may impact Veterans' ability to engage in or adhere to mental health and substance use disorder treatment. Therefore, we examined whether psychiatric functioning, substance use, and somatic problems were associated with medical marijuana use among Veterans receiving substance use disorder and/or mental health treatment. Participants (n=841) completed screening measures for a randomized controlled trial and 67 (8%) reported that they had a current medical marijuana card. Most of these participants (78%) reported using marijuana to treat severe/chronic pain. Significant bivariate differences revealed that, compared to participants without a medical marijuana card, those with a card were more likely to be in a middle income bracket, unemployed, and they had a significantly higher number of recent days of marijuana use, synthetic marijuana use, and using sedatives prescribed to them. Additionally, a significantly higher proportion of participants with a medical marijuana card scored above the clinical cutoff for posttraumatic stress disorder (PTSD) symptoms, had significantly higher severity of sleep-related problems, and reported a higher level of pain. These findings highlight the co-occurrence of substance use, PTSD symptoms, sleep-related problems, and chronic pain among Veterans who use medical marijuana. Future research should investigate the inter-relationships among medical marijuana use and other clinical issues (e.g., PTSD symptoms, sleep, pain) over time, and potential implications of medical marijuana use on treatment engagement and response.

    This cohort study examines medication use in term neonates with hypoxic-ischemic encephalopathy and seizures before and after implementation of a Neonatal Neurocritical Care Service (N = 108), which included increased seizure monitoring. Nearly all neonates received phenobarbital (96% pre- vs 95% post-Neonatal Neurocritical Care Service) and total loading dose did not vary among groups (33 [95% confidence interval 29-37] vs 30 [26-34] mg/kg). After adjustment for seizure burden, neonates managed during the Neonatal Neurocritical Care Service era, on average, received 30 mg/kg less cumulative phenobarbital (95% confidence interval 15-46 mg/kg) and were on maintenance 5 fewer days (95% confidence interval 3-8 days) than those who were treated prior to implementation of the service. In spite of the enhanced ability to detect seizures because of improved monitoring and increased vigilance by bedside practitioners, implementation of the Neonatal Neurocritical Care Service was associated with decreased use of potentially harmful phenobarbital treatment among neonates with hypoxic-ischemic encephalopathy.

    We describe a rare case of a 28 year-old male patient presenting with pruritus and increased sensitivity of the prepuce accompanied by erythematous confluent papules, unilateral nevus flammeus (NF) along almost the whole length of the right lower limb and two dysplastic nevi (DN), one located on the mid back and the other on the medial border of the right fifth toe, the latter coinciding with the NF. A biopsy of the prepuce revealed lichen sclerosus et atrophicus (LSA). Mental health assessment revealed anxiety disorder and predisposition to panic attacks. Several clinical, paraclinical and histopathological examinations were undertaken to evaluate potential underlying factors for such unusual combination of findings. Both dysplastic nevi were surgically removed. A topical calcineurin inhibitor treatment of the LSA was prescribed. For the first time in medical literature, we report an extremely rare association of NF, DN (including DN over NF) and LSA, and we are focusing our discussion on a potentially common genetic background which could explain this unusual combination of different diseases, which could in turn be caused by different mutations in common genes and/or different genes with close location in the genome.

    Thromboembolic complications represent one of the most important cause of morbidity and mortality in cancer patients. Although several data have been published demonstrating the strong association between cancer and venous thromboembolism (VTE), there is poor perception, among oncologists, of the level of risk of thrombosis and of relevance of managing VTE in these patients. The Associazione Italiana di Oncologia Medica (AIOM) has provided some recommendations to direct clinical practice according to evidence-based data concerning cancer and VTE. In fact, we conducted an extensive literature review (1996-2005) to produce evidence-based recommendations to improve perceptions of the magnitude of this risk among Italian medical and surgical oncologists and alert on the new approaches to prophylaxis and treatment of VTE in cancer patients. Levels of evidence are given according to a five-point rating system, and similarly for each key recommendation a five-point rating system suggests if the evidence is strong and indicate that the benefits do, or do not, outweigh risks and burden.

    Purpose Evidence suggests statins may influence pathways of RCC proliferation, though no study has examined the influence of statin medications on progression of RCC in humans. Materials and Methods We identified 2608 patients with localized RCC who were treated surgically between 1995–2010 at our tertiary referral center. Competing risks Cox proportional hazards models were used to evaluate the relationship between statin use and time to local recurrence or progression (metastases or death from RCC) and overall survival. Statin use was modeled as a time-dependent covariate as a sensitivity analysis. Models were adjusted for clinical and demographic features. Results Of 2608 patients, 699 (27%) were statin users at surgery. Statin users had similar pathological characteristics compared to nonusers. With a median follow-up of 36 months, there were 247 progression events. Statin use was associated with a 33% reduction in the risk of progression after surgery (HR 0.67, 95% CI 0.47–0.96, p=0.028) and an 11% reduction in overall mortality that was not significant (HR 0.89, 95% CI 0.71–1.13, p=0.3). Modeling statin use as time-dependent covariate attenuated the risk reduction in progression to 23% (HR 0.77, p=0.12) and augmented the risk reduction in overall survival (HR 0.71; p=0.002). Conclusions In our cohort, statin use was associated with a reduced risk of progression and overall mortality, though this effect was sensitive to method of analysis. If validated in other cohorts, this finding warrants consideration of prospective research on statins in the adjuvant setting. PMID:24291547

    Purpose: Information about the safety of herbal medicine often comes from case reports published in the medical literature, thus necessitating good quality reporting of these adverse events. The purpose of this study was to perform a systematic review of the comprehensiveness of reporting of published case reports of adverse events associated with herb use in the pediatric population. Methods: Electronic literature search included 7 databases and a manual search of retrieved articles from inception through 2010. We included published case reports and case series that reported an adverse event associated with exposure to an herbal product by children under the age of 18 years old. We used descriptive statistics. Based on the International Society of Epidemiology's “Guidelines for Submitting Adverse Events Reports for Publication,” we developed and assigned a guideline adherence score (0-17) to each case report. Results: Ninety-six unique journal papers were identified and represented 128 cases. Of the 128 cases, 37% occurred in children under 2 years old, 38% between the ages of 2 and 8 years old, and 23% between the ages of 9 and 18 years old. Twenty-nine percent of cases were the result of an intentional ingestion while 36% were from an unintentional ingestion. Fifty-two percent of cases documented the Latin binomial of the herb ingredients; 41% documented plant part. Thirty-two percent of the cases reported laboratory testing of the herb, 20% documented the manufacturer of the product, and 22% percent included an assessment of the potential concomitant therapies that could have been influential in the adverse events. Mean guideline adherence score was 12.5 (range 6-17). Conclusions: There is considerable need for improvement in reporting adverse events in children following herb use. Without better quality reporting, adverse event reports cannot be interpreted reliably and do not contribute in a meaningful way to guiding recommendations for medicinal herb use

    2014-01-01

    Objectives We aimed to investigate the association between concealing emotions at work and medical utilization. Methods Data from the 2007–2009 4th Korea National Health and Nutrition Examination Survey (KNHANES IV) was used, 7,094 participants (3,837 males, 3,257 females) aged between 20 and 54 who were economically active and completed all necessary questionnaire items were included. Odds ratios (ORs) and 95% confidence intervals (95% CI) for differences in hospitalization, outpatient visits, and pharmaceutical drug use between those who concealed their emotions and those who did not were investigated using logistic regression models with and without gender stratification. Results Among those who concealed their emotions (n = 2,763), 47.4% were females, and 50.1% had chronic disease. In addition, 9.7% of the concealing emotions group had been hospitalized within the last year, 24.8% had been outpatients in the last two weeks, and 28.3% had used pharmaceutical drugs in the last two weeks. All ORs represent the odds of belonging to the concealing emotions group over the non-concealing emotions group. After adjustment for individual, occupational, socioeconomic and disease factors, the adjusted ORs (95% CI) in hospitalization are 1.29 (1.08 ~ 1.53) in the total population, 1.25 (0.98 ~ 1.60) in males and 1.30 (1.02 ~ 1.66) in females, in outpatient visits are 1.15 (1.02 ~ 1.29) in the total population, 1.05 (0.88 ~ 1.24) in males and 1.25 (1.06 ~ 1.47) in females and in pharmaceutical drug use are 1.12 (1.01 ~ 1.25) in the total population, 1.08 (0.92 ~ 1.27) in males and 1.14 (0.98 ~ 1.33) in females. Conclusions Those who concealed their emotions at work were more likely to use medical services. Moreover, the health effects of concealing emotions at work might be more detrimental in women than in men. PMID:25852941

    In the application area of aerospace tribology, researchers and developers must guarantee the highest degree of reliability for materials, components, and systems. Even a small tribological failure can lead to catastrophic results. The absence of the required knowledge of tribology, as Professor H.P. Jost has said, can act as a severe brake in aerospace vehicle systems-and indeed has already done so. Materials and coatings must be able to withstand the aerospace environments that they encounter, such as vacuum terrestrial, ascent, and descent environments; be resistant to the degrading effects of air, water vapor, sand, foreign substances, and radiation during a lengthy service; be able to withstand the loads, stresses, and temperatures encountered form acceleration and vibration during operation; and be able to support reliable tribological operations in harsh environments throughout the mission of the vehicle. This presentation id divided into two sections: surface properties and technology practice related to aerospace tribology. The first section is concerned with the fundamental properties of the surfaces of solid-film lubricants and related materials and coatings, including carbon nanotubes. The second is devoted to applications. Case studies are used to review some aspects of real problems related to aerospace systems to help engineers and scientists to understand the tribological issues and failures. The nature of each problem is analyzed, and the tribological properties are examined. All the fundamental studies and case studies were conducted at the NASA Glenn Research Center.

    2012-01-01

    BACKGROUND: Shift work has been associated with irritable bowel syndrome (IBS), which includes gastrointestinal symptoms such as abdominal pain, constipation and diarrhea. Overnight call shifts also lead to a disruption of the endogenous circadian rhythm. HYPOTHESIS: Medical students who perform intermittent overnight call shifts will demonstrate a higher prevalence of IBS symptoms when compared with medical students who perform no overnight call shifts. METHODS: First- and second-year (preclinical) medical students have no overnight call requirements, whereas third- and fourth-year medical (clerkship) students do have overnight call requirements. All medical students at the Schulich School of Medicine and Dentistry (London, Ontario) were invited to complete an anonymous, web-based survey or an identical paper copy that included demographic data, the Rome III questionnaire and the IBS-Quality of Life measure (IBS-QOL). The prevalence of IBS symptoms and quality of life secondary to those symptoms were determined. RESULTS: Data were available for 247 medical students (110 pre-clinical students, 118 clerkship students and 19 excluded surveys). There was no significant difference in the presence of IBS between preclinical and clerkship students (21 of 110 [19.1%] versus 26 of 118 [22.0%]; P=0.58). The were no significant differences in mean (± SD) IBS-QOL score of those with IBS between preclinical (43.5±8.3) and clerkship students (45.7±13.8) (P=0.53). CONCLUSIONS: Participation in overnight call was not associated with the development of IBS or a lower quality of life secondary to IBS in medical students. PMID:22590702

    Objective: The aim of the present study was to clarify the current work and sleep situations of physicians in Japan and to clarify the association between these situations and excessive daytime sleepiness as well as medical incidents. Methods: A self-administered questionnaire survey was conducted among the members of the Japan Medical Association in 2008. The randomly selected subjects comprised 3,000 male physicians and 1,500 female physicians. Results: Valid responses were obtained from 3,486 physicians (2,298 men and 1,188 women). Mean sleep duration was 6 h 36 min for men and 6 h 8 min for women. The prevalence of lack of rest due to sleep deprivation was 30.4% among men and 36.6% among women; the prevalence of insomnia was 21.0% and 18.1%, respectively; and the prevalence of EDS was 3.5%. The adjusted odds ratio for EDS was high for physicians who reported short sleep duration, lack of rest due to sleep deprivation, and a high frequency of on-call/overnight work. Physicians who had experienced a medical incident within the previous one month accounted for 19.0% of participants. The adjusted odds ratio for medical incidents was high for those subjected to long working hours, high frequency of on-call/overnight works, lack of rest due to sleep deprivation, and insomnia. Conclusion: In order to facilitate optimal health management for physicians as well as securing medical safety, it is important to fully consider the work and sleep situations of physicians.

    Wilson, William; Atkinson, Gary

    2007-01-01

    Wireless sensors and sensor networks is an emerging technology area with many applications within the aerospace industry. Integrated vehicle health monitoring (IVHM) of aerospace vehicles is needed to ensure the safety of the crew and the vehicle, yet often high costs, weight, size and other constraints prevent the incorporation of instrumentation onto spacecraft. This paper presents a few of the areas such as IVHM, where new wireless sensing technology is needed on both existing vehicles as well as future spacecraft. From ground tests to inflatable structures to the International Space Station, many applications could receive benefits from small, low power, wireless sensors. This paper also highlights some of the challenges that need to overcome when implementing wireless sensor networks for aerospace vehicles.

    1991-01-01

    Few of the heart-lung interactions that are discussed have been studied in any detail in the aerospace environment, but is seems that many such interactions must occur in the setting of altered accelerative loadings and pressure breathing. That few investigations are in progress suggests that clinical and academic laboratory investigators and aerospace organizations are further apart than during the pioneering work on pressure breathing and acceleration tolerance in the 1940s. The purpose is to reintroduce some of the perennial problems of aviation physiology as well as some newer aerospace concerns that may be of interest. Many possible heart-lung interactions are pondered, by necessity often drawing on data from within the aviation field, collected before the modern understanding of these interactions developed, or on recent laboratory data that may not be strictly applicable. In the field of zero-gravity effects, speculation inevitably outruns the sparse available data.

    1992-01-01

    Nickel metal hydride and silver metal hydride batteries are being developed for aerospace applications. There is a growing market for smaller, lower cost satellites which require higher energy density power sources than aerospace nickel-cadmium at a lower cost than space nickel-hydrogen. These include small LEO satellites, tactical military satellites and satellite constellation programs such as Iridium and Brilliant Pebbles. Small satellites typically do not have the spacecraft volume or the budget required for nickel-hydrogen batteries. NiCd's do not have adequate energy density as well as other problems such as overcharge capability and memory effort. Metal hydride batteries provide the ideal solution for these applications. Metal hydride batteries offer a number of advantages over other aerospace battery systems.

    Research efforts to reduce the dependence of the aerospace industry on strategic metals, such as cobalt (Co), columbium (Cb), tantalum (Ta), and chromium (Cr), by providing the materials technology needed to minimize the strategic metal content of critical aerospace components for gas turbine engines are addressed. Thrusts in three technology areas are identified: near term activities in the area of strategic element substitution; intermediate-range activities in the area of materials processing; and long term, high risk activities in the area of 'new classes' of high temprature metallic materials. Specifically, the role of cobalt in nickel-base and cobalt-base superalloys vital to the aerospace industry is examined along with the mechanical and physical properties of intermetallics that will contain a minimum of the stragetic metals.

    Chellman, D. J.; Langenbeck, S. L.

    1993-01-01

    Advanced metallic materials within the Al-base family are being developed for applications on current and future aerospace vehicles. These advanced materials offer significant improvements in density, strength, stiffness, fracture resistance, and/or higher use temperature which translates into improved vehicle performance. Aerospace applications of advanced metallic materials include space structures, fighters, military and commercial transport aircraft, and missiles. Structural design requirements, including not only static and durability/damage tolerance criteria but also environmental considerations, drive material selections. Often trade-offs must be made regarding strength, fracture resistance, cost, reliability, and maintainability in order to select the optimum material for a specific application. These trade studies not only include various metallic materials but also many times include advanced composite materials. Details of material comparisons, aerospace applications, and material trades will be presented.

    2010-01-01

    Aggregate nuclear plant failure data is used to produce generic common-cause factors that are specifically for use in the common-cause failure models of NUREG/CR-5485. Furthermore, the models presented in NUREG/CR-5485 are specifically designed to incorporate two significantly distinct assumptions about the methods of surveillance testing from whence this aggregate failure data came. What are the implications of using these NUREG generic factors to model the common-cause failures of aerospace systems? Herein, the implications of using the NUREG generic factors in the modeling of aerospace systems are investigated in detail and strong recommendations for modeling the common-cause failures of aerospace systems are given.

    Green, M. K.

    1972-01-01

    The feasibility of a program to effect transfer of aerospace professional people from the ranks of the unemployed into gainful employment in the small business community was investigated. The effectiveness of accomplishing transfer of technology from the aerospace effort into the private sector through migration of people rather than products or hardware alone was also studied. Two basic methodologies were developed. One involves the matching of ex-aerospace professionals and small companies according to their mutual needs. A training and indoctrination program is aimed at familiarizing the professional with the small company environment, and a program of follow-up counseling is defined. The second methodology incorporates efforts to inform and arouse interest among the nonaerospace business community toward affirmative action programs that will serve mutual self-interests of the individuals, companies, and communities involved.

    Holst, Ruth; Funk, Carla J.

    2005-01-01

    Objectives: Medical Library Association (MLA) members were surveyed to gather background about the current state of expert searching in institutions. The survey results were intended to guide the recommendations of the Task Force on Expert Searching for promoting the importance of expert searching and implementing those recommendations. Methods: MLA members were surveyed, and data obtained from the survey were compiled and analyzed to answer three general questions: what is the perceived value of searching skills to the institution, how do health sciences librarians maintain and improve their searching skills, and how are searching services promoted and/or mandated in the institution. Results: There were 256 responses to the survey. Over 95% of the respondents saw their expert-searching skills were of value to their institutions, primarily through performing mediated searches and search consultations. Over 83% of the respondents believed that their searching skills had improved over the past 10 years. Most indicated that continued training was very important in maintaining and improving their skills. Respondents promoted searching services most frequently through orientations, brochures, and the libraries' Web pages. No respondent's institution mandated expert searching. Less than 2% of respondents' institutions had best practice guidelines related to expert searching, and only about 8% had guidelines or policies that identified situations where expert searching was recommended. Conclusions: The survey supports the belief that health sciences librarians still play a valuable role in searching, particularly in answering questions about treatment options and in providing education. It also highlights the need for more expert searching courses. There has been minimal discussion about the perceived need for expert-searching guidelines in the institutions represented by survey respondents. PMID:15685274

    2014-11-01

    In this study, we developed an integrated hospital-associated urinary tract infection (HAUTI) surveillance information system (called iHAUTISIS) based on existing electronic medical records (EMR) systems for improving the work efficiency of infection control professionals (ICPs) in a 730-bed, tertiary-care teaching hospital in Taiwan. The iHAUTISIS can automatically collect data relevant to HAUTI surveillance from the different EMR systems, and provides a visualization dashboard that helps ICPs make better surveillance plans and facilitates their surveillance work. In order to measure the system performance, we also created a generic model for comparing the ICPs' work efficiency when using existing electronic culture-based surveillance information system (eCBSIS) and iHAUTISIS, respectively. This model can demonstrate a patient's state (unsuspected, suspected, and confirmed) and corresponding time spent on surveillance tasks performed by ICPs for the patient in that state. The study results showed that the iHAUTISIS performed better than the eCBSIS in terms of ICPs' time cost. It reduced the time by 73.27 s, when using iHAUTISIS (114.26 s) and eCBSIS (187.53 s), for each patient on average. With increased adoption of EMR systems, the development of the integrated HAI surveillance information systems would be more and more cost-effective. Moreover, the iHAUTISIS adopted web-based technology that enables ICPs to online access patient's surveillance information using laptops or mobile devices. Therefore, our system can further facilitate the HAI surveillance and reduce ICPs' surveillance workloads. PMID:25154644

    Introduction: Obesity is a condition in which excess body fat accumulates, which leads to various adverse effects on health, particularly cardiovascular diseases (CVDs), which reduce life expectancy and/or increase health problems. Fast food consumption is one of the factors which have been reported as a cause of obesity. Body mass index (BMI) is used to assess obesity and overweight, which can be calculated by using the formula, weight in kg, divided by square of height in metres. Aim: This study focused on the relationship of body mass index with fast food consumption, associated soft drink consumption and physical activity. Methods: Descriptive cross-sectional study was conducted in Department of Biochemistry, SBKS MI and RC, and Sumandeep Vidyapeeth. This study was approved by the ethical review board .One hundred and forty seven medical students from 1st year MBBS course were included in this study. Self-structured questionnaire was used, which contained several data like information on age, height, weight, education level. The formula used for calculating BMI was, weight in kg, divided by square of height in metres (Kg/m2). Results: In our study, out of 147 students, a total of 138 students (more than 90%) used to have fast food. Among these, a total of 47 students (34.05%) were pre-obese and obese. Out of 147 students, 87 students (59.18%) were in normal weight range, while 13 (8.84%) students were underweight. Statistical Analysis: Data was compiled in an Excel worksheet and it was analyzed for percentages and proportions. Chi-square and Pearson’s correlation test were also applied wherever they were applicable and Alpha error was set at a 5% level. Conclusion: In our study, a significant relationship was found between BMI and fast food consumption, less physical activity, and intake of soft drinks. PMID:24995170

    Residency is a stressful period in a physician's development, characterized by long work hours, time pressure, and excessive work load, that can exert negative effects on residents' mental health. Job burnout and negative work-home interference may play a major role in residents' mental health problems. The present study used the job demands-resources model as a theoretical framework to examine the way in which job demands (e.g., workload, emotional demands) and job resources (e.g., supervisor support, job autonomy) were associated with residents' mental health. From a pool of 290 medical residents, 264 (91 %) completed the questionnaires. Applying structural equation modeling techniques, the results showed that greater emotional exhaustion (β = -.65, SE = .09, p < .001) and more work-home interference (β = -.26, SE = .10, p < .05) were related to poor mental health. Specific job demands (i.e., high workload) and particular job resources (i.e., low opportunities for professional development and low supervisor support) were related to poor mental health not directly but only indirectly, via emotional exhaustion or work-home interference. Thus, through work-related emotional exhaustion, the impact of work conditions might be transmitted to and interfere with non-work related domains such as family life, as well as with domain-unspecific aspects of well-being, such as mental health and psychological distress. Implications of the results and suggestions for future research and practice are outlined. PMID:25554496

    In this paper, we described the Comprehensive AeroSpace Index (CASI), a financial index aimed at representing the economic performance of the aerospace industry. CASI is build upon a data set of approximately 20 years of daily close prices set, from January 1987 to June 2007, from a comprehensive sample of leading aerospace-related companies with stocks negotiated on the New York Exchange (NYSE) and on the over-the-counter (OTC) markets. We also introduced the sub-indices CASI-AERO, for aeronautical segment, and CASI-SAT, for satellite segment, and considered the relation between them. These three indices are compared to others aerospace indices and to more traditional general financial indices like DJIA, S&P500 and Nasdaq. Our results have shown that the CASI is an index that describes very well the aerospace sector behavior, since it is able to reflect the aeronautical segment comportment as well as the satellite one. Therefore, in this sense, it can be considered as a representative index of the aerospace sector. Moreover, the creation of two sub-indices, the CASI-AERO and the CASI-SAT, allows to elucidate capital movements within the aerospace sector, particularly those of speculative nature, like the dot.com bubble and crash of 1998-2001.

    The purpose of the Aerospace National Emission Standard for Hazardous Air Pollutants (NESHAP) is to minimize emissions of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from major sources who manufacture or rework aerospace vehicles or components. The NESHAP requires emission reductions through implementation of work practices, application of slower evaporating solvents and coatings with low-HAP and low-VOC content, usage of high transfer efficiency spray equipment, and installation of high capture efficiency exhaust filtration for coatings containing metals. The rule also requires extensive monitoring, recordkeeping, and self-reporting to track compliance. For existing sources the rule becomes effective September 1,1998. Over the past year the Puget Sound Air Pollution Control Agency (PSAPCA) has worked with the Boeing Company and EPA to identify the requirements of the aerospace NESHAP, understand what it means in everyday practice, and develop an enforcement strategy for ensuring compliance. A workshop was held with aerospace manufacturers, local regulators, and EPA to discuss implementation of the rule. Issues regarding compliance efforts and determinations were openly discussed. Subsequent to the workshop, PSAPCA and the Boeing Company participated in several mock inspections to review facility compliance efforts before the rule became effective. Collaborative efforts also ensued to develop operating permit monitoring requirements. Aerospace NESHAP requirements were incorporated into these permits. There are still questions regarding compliance determinations that must be further discussed and resolved. But by using the collaborative approach and having regulators and sources working together, there is a process to work out answers and approaches that will lead to an increased mutual understanding of the aerospace NESHAP and eventual compliance with the standard.

    OBJECTIVE To study the medical and financial outcomes associated with surgery in the elderly obese patient and ask if obesity itself influences outcomes above and beyond effects from comorbidities known to be associated with obesity. BACKGROUND Obesity is a surgical risk factor not present in Medicare’s risk adjustment or payment algorithms, as BMI is not collected in administrative claims. METHODS 2045 severely or morbidly obese patients (BMI ≥ 35 kg/m2, age between 65 and 80) selected from 15,914 elderly patients in 47 hospitals undergoing hip and knee surgery, colectomy, and thoracotomy were matched to two sets of 2045 non-obese patients (BMI = 20 – 30 kg/m2). A “limited match” controlled for age, sex, race, procedure and hospital. A “complete match” also controlled for 30 additional factors such as diabetes and admission clinical data from chart abstraction. RESULTS Mean BMI in the obese was 40kg/m2 versus 26kg/m2 in the non-obese. In the complete match, obese patients displayed increased odds of wound infection: OR = 1.64 (95% CI 1.21, 2.21); renal dysfunction: OR = 2.05(1.39, 3.05); urinary tract infection: OR = 1.55 (1.24, 1.94); hypotension: OR = 1.38 (1.07, 1.80); respiratory events: OR = 1.44 (1.19, 1.75); 30-day readmission: OR = 1.38 (1.08, 1.77); and a 12% longer length of stay (8%, 17%); Provider costs were 10% (7%, 12%) greater in the obese than non-obese, while Medicare payments increased only 3% (2%, 5%). Findings were similar in the limited match. CONCLUSIONS Obesity increases the risks and costs of surgery. Better approaches are needed to reduce these risks. Furthermore, to avoid incentives to under-serve this population, Medicare should consider incorporating incremental costs of caring for obese patients into payment policy and include obesity in severity adjustment models.

    Background Hyponatremia has been known as an important predictor of clinical outcomes in patients with heart failure (HF). While information on hyponatremia in patients with HF has been available abundantly, information on factors associated with increased risk of developing hospital-acquired hyponatremia (HAH) is still limited. Objective To identify patients and medication-related factors associated with HAH in patients hospitalized from HF. Setting Fatmawati Hospital in Jakarta, Indonesia. Methods This is a nested case-control study with patients developing HAH served as case group and each patient in case group was matched by age and gender to three patients in control group. Patients included in this study are patients hospitalized from HF, and coded with I.50 according to ICD-10, during 2011-2013 at Fatmawati Hospital in Jakarta, Indonesia. Information retrieved from patients' medical records included demographic profiles, vital signs and symptoms at admission, past medical history, medication during hospitalization and clinical chemistry laboratory records. Multivariable logistic regression analysis was performed to find out patient and treatment-related factors associated with the development of HAH. Main outcome measures Patients and medication related factors having significant association with HAH. Results Four hundreds sixty-four patients were included in this study and 45 of them (9.7 %) met criteria of developing HAH so then, accordingly, 135 patients were selected as controls. 36 patient- and 22 treatment-related factors were analyzed in univariate logistic regression resulted in 20 factors having p value <0.2 and were included in multivariable logistic regression analysis. Final factors showing significant association with HAH are presence of ascites at admission (odds ratio = 4.7; 95 % confidence interval 1.9-11.5) and administration of amiodarone (3.2; 1.3-7.4) and heparin (3.1; 1.2-7.3) during hospital stay.

    The aerospace vehicle interactive design (AVID) is a computer aided design that was developed for the conceptual and preliminary design of aerospace vehicles. The AVID system evolved from the application of several design approaches in an advanced concepts environment in which both mission requirements and vehicle configurations are continually changing. The basic AVID software facilitates the integration of independent analysis programs into a design system where the programs can be executed individually for analysis or executed in groups for design iterations and parametric studies. Programs integrated into an AVID system for launch vehicle design include geometry, aerodynamics, propulsion, flight performance, mass properties, and economics.

    Background Long-term exposure to anti-tuberculosis medication increases risk of adverse drug reactions and toxicity. The objective of this investigation was to determine factors associated with anti-tuberculosis adverse drug reactions in Lima, Peru, with special emphasis on MDR-TB medication, HIV infection, diabetes, age and tobacco use. Methodology and Results A case-control study was performed using information from Peruvian TB Programme. A case was defined as having reported an anti-TB adverse drug reaction during 2005–2010 with appropriate notification on clinical records. Controls were defined as not having reported a side effect, receiving anti-TB therapy during the same time that the case had appeared. Crude, and age- and sex-adjusted models were calculated using odds ratios (OR) and 95% confidence intervals (95%CI). A multivariable model was created to look for independent factors associated with side effect from anti-TB therapy. A total of 720 patients (144 cases and 576 controls) were analyzed. In our multivariable model, age, especially those over 40 years (OR = 3.93; 95%CI: 1.65–9.35), overweight/obesity (OR = 2.13; 95%CI: 1.17–3.89), anemia (OR = 2.10; IC95%: 1.13–3.92), MDR-TB medication (OR = 11.1; 95%CI: 6.29–19.6), and smoking (OR = 2.00; 95%CI: 1.03–3.87) were independently associated with adverse drug reactions. Conclusions Old age, anemia, MDR-TB medication, overweight/obesity status, and smoking history are independent risk factors associated with anti-tuberculosis adverse drug reactions. Patients with these risk factors should be monitored during the anti-TB therapy. A comprehensive clinical history and additional medical exams, including hematocrit and HIV-ELISA, might be useful to identify these patients. PMID:22110689

    Objectives To investigate medical student's self-efficacy at the time of finishing their rural clinical school (RCS) placement and factors associated with self-efficacy. Secondary aims are to explore whether interest levels or self-efficacy are associated with rural or remote career intentions. Design, setting and participants A cross-sectional study of medical students who had completed their RCS term in 17 Australian universities. Data were derived from the 2013 Federation of Rural Australian Medical Educators (FRAME) evaluation survey. Questionnaire responses were analysed from 653 medical students from regional Australia. All 732 students who completed their RCS term in 2013 were invited to participate. Primary and secondary outcome measures Rural self-efficacy: Six questions to measure self-efficacy beliefs in rural medical practice, based on the sources of self-efficacy described by Bandura. Rural career intention: Students were asked to identify their preferred location for future practice. The options were, Capital or Major City; Inner regional city or large town; Smaller town and very remote area. Results Questionnaire responses were analysed from 653 medical students from regional Australia (response rate 89.2%). 83.8% of all students recalled an increase in their interest levels for rural medicine as a result of their RCS experience. Actual career intention to work in a regional area or rural area was 60.2%. Bivariate analyses showed female gender (p=0.003), rural background (p<0.001), an RCS preference for clinical training (p<0.001) and general practice intentions (p=0.004) were factors associated with higher levels of self-efficacy. Logistic regression analyses showed that self-efficacy was independently associated with increased interest in rural medicine (OR 1.4 (95% CI 1.3 to 1.5)) and rural career intent (OR 1.2 (95% CI 1.1 to 1.3)).

    Background Low health literacy is associated with low adherence to self-management in many chronic diseases. Additionally, health beliefs are thought to be determinants of self-management behaviors. In this study we sought to determine the association, if any, of health literacy and health beliefs among elderly individuals with COPD. Methods We enrolled a cohort of patients with COPD from two academic urban settings in New York, NY and Chicago, IL. Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Using the framework of the Self-Regulation Model, illness and medication beliefs were measured with the Brief Illness Perception Questionnaire (B-IPQ) and Beliefs about Medications Questionnaire (BMQ). Unadjusted analyses, with corresponding Cohen’s d effect sizes, and multiple logistic regression were used to assess the relationships between HL and illness and medication beliefs. Results We enrolled 235 participants, 29% of whom had low health literacy. Patients with low health literacy were more likely to belong to a racial minority group (p<0.001), not be married (p = 0.006), and to have lower income (p<0.001) or education (p<0.001). In unadjusted analyses, patients with low health literacy were less likely to believe they will always have COPD (p = 0.003, Cohen’s d = 0.42), and were more likely to be concerned about their illness ((p = 0.04, Cohen’s d = 0.17). In analyses adjusted for sociodemographic factors and other health beliefs, patients with low health literacy were less likely to believe that they will always have COPD (odds ratio [OR]: 0.78, 95% confidence interval [CI]: 0.65–0.94). In addition, the association of low health literacy with expressed concern about medications remained significant (OR: 1.20, 95% CI: 1.05–1.37) though the association of low health literacy with belief in the necessity of medications was no longer significant (OR: 0.92, 95% CI: 0.82–1.04).

    Purpose: This lecture explores changes in the medical library profession over the last fifty years, as revealed by individual word usage in a body of literature. Methods: I downloaded articles published in the Bulletin of the Medical Library Association and Journal of the Medical Library Association between 1961 and 2000 to create an electronic corpus and tracked annual frequency of individual word usage. I used frequency sparklines of words, matching one of four archetypal shapes (level, rise, fall, and rise-and-fall) to identify significant words. Results: Most significant words fell into the categories of environment, management, technology, and research. Based on word usage changes, the following trends are revealed: Compared to 1961, today's medical librarians are more concerned with digital information, not physical packages. We prefer information to be evidence-based. We focus more on health than medicine. We are reaching out to new constituents, sometimes leaving our building to do so. Teaching has become important for us. We run our libraries more like businesses, using constantly changing technology. We are publishing more research articles. Conclusions: Although these words were chosen by individual authors to tell their particular stories, in the aggregate, our words reveal our story of change in our profession. PMID:23405042

    We measured mortality rates in a cohort of 20,508 aerospace workers who were followed up over the period 1950-1993. A total of 4,733 workers had occupational exposure to trichloroethylene. In addition, trichloroethylene was present in some of the washing and drinking water used at the work site. We developed a job-exposure matrix to classify all jobs by trichloroethylene exposure levels into four categories ranging from "none" to "high" exposure. We calculated standardized mortality ratios for the entire cohort and the trichloroethylene exposed subcohort. In the standardized mortality ratio analyses, we observed a consistent elevation for nonmalignant respiratory disease, which we attribute primarily to the higher background rates of respiratory disease in this region. We also compared trichloroethylene-exposed workers with workers in the "low" and "none" exposure categories. Mortality rate ratios for nonmalignant respiratory disease were near or less than 1.00 for trichloroethylene exposure groups. We observed elevated rare ratios for ovarian cancer among those with peak exposure at medium and high levels] relative risk (RR) = 2.74; 95% confidence interval (CI) = 0.84-8.99] and among women with high cumulative exposure (RR = 7.09; 95% CI = 2.14-23.54). Among those with peak exposures at medium and high levels, we observed slightly elevated rate ratios for cancers of the kidney (RR = 1.89; 95% CI = 0.85-4.23), bladder (RR = 1.41; 95% CI = 0.52-3.81), and prostate (RR = 1.47; 95% CI = 0.85-2.55). Our findings do not indicate an association between trichloroethylene exposure and respiratory cancer, liver cancer, leukemia or lymphoma, or all cancers combined. PMID:9647907

    Mass gatherings are heterogeneous in terms of size, duration, type of event, crowd behavior, demographics of the participants and spectators, use of recreational substances, weather, and environment. The goals of health and medical services should be the provision of care for participants and spectators consistent with local standards of care, protection of continuing medical service to the populations surrounding the event venue, and preparation for surge to respond to extraordinary events. Pre-event planning among jurisdictional public health and EMS, acute care hospitals, and event EMS is essential, but should also include, at a minimum, event security services, public relations, facility maintenance, communications technicians, and the event planners and organizers. Previous documented experience with similar events has been shown to most accurately predict future needs. Future work in and guidance for mass gathering medical care should include the consistent use and further development of universally accepted consistent metrics, such as Patient Presentation Rate and Transfer to Hospital Rate. Only by standardizing data collection can evaluations be performed that link interventions with outcomes to enhance evidence-based EMS services at mass gatherings. Research is needed to evaluate the skills and interventions required by EMS providers to achieve desired outcomes. The event-dedicated EMS Medical Director is integral to acceptable quality medical care provided at mass gatherings; hence, he/she must be included in all aspects of mass gathering medical care planning, preparations, response, and recovery. Incorporation of jurisdictional EMS and community hospital medical leadership, and emergency practitioners into these processes will ensure that on-site care, transport, and transition to acute care at appropriate receiving facilities is consistent with, and fully integrated into the community's medical care system, while fulfilling the needs of event

    Rocky Mountain spotted fever (RMSF) is an emerging public health issue on some American Indian reservations in Arizona. RMSF causes an acute febrile illness that, if untreated, can cause severe illness, permanent sequelae requiring lifelong medical support, and death. We describe costs associated with medical care, loss of productivity, and death among cases of RMSF on two American Indian reservations (estimated population 20,000) between 2002 and 2011. Acute medical costs totaled more than $1.3 million. This study further estimated $181,100 in acute productivity lost due to illness, and $11.6 million in lifetime productivity lost from premature death. Aggregate costs of RMSF cases in Arizona 2002–2011 amounted to $13.2 million. We believe this to be a significant underestimate of the cost of the epidemic, but it underlines the severity of the disease and need for a more comprehensive study. PMID:26033020

    Background: The health status of medical practitioners can potentially impact their ability to counsel patients. The purpose of the study was to examine the prevalence of obesity and behaviors associated with the development of metabolic disease among medical practitioners in the country of Jordan. Materials and Methods: The participants were 748 (male n = 285, 32.3 years ± 7.3, female n = 463, 29.7 years ± 5.7) randomly selected pharmacists, nurses, physicians, medical lab technicians, and radiation specialists from a variety of medical institutions in Jordan. A short 25-item validated instrument was chosen for this investigation. After the survey was administered and data were tabulated, one-way analysis of variance and Pearson's Chi-square analysis were conducted to examine differences in reported risk behaviors (low physical activity [PA], smoking) and obesity by gender, age and medical specialty. Results: Descriptive analysis revealed that 20.9% of the participants self-reported as smokers of cigarettes, 47.9% were either overweight or obese, and 52.9% reported no days of planned PA on average per week. The results suggested a difference in body mass index (BMI) classification (F = 17.9, P ≤ 0.001) and smoking (F = 5.33, P = 0.021) by age. Mean age associated with being underweight was 26.4 years for normal weight 29.3 years for overweight 31.6 years and finally for obese was 34.5 years. Chi-square test resulted in differences by gender (χ2 > 50, P ≤ 0.001) for BMI (males: 26.4 ± 3.7; females: 24.6 ± 3.7), PA (males no planned PA 61.1%, females 47.9%) and smoking (males 43.1% smokers, females 7.1%). Researchers discovered that medical specialty was related to differences in reported smoking (χ2 = 26.5, P ≤ 0.001) and days of planned PA (χ2 = 24.2, P = 0.019). Conclusions: Within the population of medical practitioners there is still a high incidence of obesity and risk behaviors associated with metabolic diseases. It also appears that these

  5. Depression in primary TKA and higher medical comorbidities in revision TKA are associated with suboptimal subjective improvement in knee function

    PubMed Central

    2014-01-01

    Background To characterize whether medical comorbidities, depression and anxiety predict patient-reported functional improvement after total knee arthroplasty (TKA). Methods We analyzed the prospectively collected data from the Mayo Clinic Total Joint Registry for patients who underwent primary or revision TKA between 1993–2005. Using multivariable-adjusted logistic regression analyses, we examined whether medical comorbidities, depression and anxiety were associated with patient-reported subjective improvement in knee function 2- or 5-years after primary or revision TKA. Odds ratios (OR), along with 95% confidence intervals (CI) and p-value are presented. Results We studied 7,139 primary TKAs at 2- and 4,234 at 5-years; and, 1,533 revision TKAs at 2-years and 881 at 5-years. In multivariable-adjusted analyses, we found that depression was associated with significantly lower odds of 0.5 (95% confidence interval [CI]: 0.3 to 0.9; p = 0.02) of ‘much better’ knee functional status (relative to same or worse status) 2 years after primary TKA. Higher Deyo-Charlson index was significantly associated with lower odds of 0.5 (95% CI: 0.2 to 1.0; p = 0.05) of ‘much better’ knee functional status after revision TKA for every 5-point increase in score. Conclusions Depression in primary TKA and higher medical comorbidity in revision TKA cohorts were associated with suboptimal improvement in index knee function. It remains to be seen whether strategies focused at optimization of medical comorbidities and depression pre- and peri-operatively may help to improve TKA outcomes. Study limitations include non-response bias and the use of diagnostic codes, which may be associated with under-diagnosis of conditions. PMID:24725511

    Artificial Intelligence (AI) is currently being used for business-oriented, money-making applications, such as medical diagnosis, computer system configuration, and geological exploration. The present paper has the objective to assess new AI tools and techniques which will be available to assist aerospace managers in the accomplishment of their tasks. A study conducted by Brown and Cheeseman (1983) indicates that AI will be employed in all traditional management areas, taking into account goal setting, decision making, policy formulation, evaluation, planning, budgeting, auditing, personnel management, training, legal affairs, and procurement. Artificial intelligence/expert systems are discussed, giving attention to the three primary areas concerned with intelligent robots, natural language interfaces, and expert systems. Aspects of information retrieval are also considered along with the decision support system, and expert systems for project planning and scheduling.
