  1. The general practitioner and mental health problems: challenges and strategies for medical education

    Directory of Open Access Journals (Sweden)

    Dinarte Alexandre Ballester

    Full Text Available CONTEXT AND OBJECTIVE: Within the context of primary health care and mental disorders, our aim was to study the opinions of general practitioners regarding attendance of people with mental health problems. DESIGN AND SETTING: Qualitative focal group study among primary care services in the cities of Porto Alegre and Parobé, State of Rio Grande do Sul. METHODS: A deliberately selected sample of 41 general practitioners who were working in basic health services met in focal groups. Two videos were presented, which simulated consultations for patients with depression and psychoses. The discussions about the identification and handling of mental health problems were recorded and assessed via content analysis. RESULTS: The opinions related to the difficulties of diagnosing and treating mental problems, the involvement of relatives in caring for patients, the difficulty of compliance with the treatment, the uncertainty experienced by physicians and the difficulty of referring patients to specialized services. CONCLUSIONS: The general practitioners indicated that they perceived the mental health problems among their clientele, but the diagnosis and treatment of these problems are still seen as a task for specialists. The challenge of continuing education on mental health requires methods of interactive and critical teaching, such as the problem-based approach.

    2016-12-01

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

    Full Text Available Introduction:Today, shift work is considered as a necessity in many jobs and for some 24-hour services the use of shift-work is growing. However, shift work can lead to physiological and psycho-social problems for shift workers. This study aimed to determine the effects of shift work on the associated health problems, together with the demographic and job characteristics underlying the problems, among the medical and diagnostic staff of the general teaching hospitals affiliated to Shiraz University of Medical Sciences in 2012. Method:This study was an applied, cross-sectional and descriptive-analytical one. The study employed a sample of 205 employees from the medical and diagnostic staff using stratified sampling proportional to the size and simple random sampling methods. Data were collected using the Survey of Shift workers (SOS questionnaire, validity and reliability of which have already been confirmed. Finally, the collected data were analyzed using SPSS 16.0 software through ANOVA, Chi-square, Independent-Samples T-Test, as well as Pearson Correlation Coefficient. A P<0.05 was considered statistically significant. Results: The results showed that among the demographic and job characteristics studied, the individual, family and social problems had significant associations with work schedules, shift work and job satisfaction. In addition, there were significant associations between musculoskeletal disorders and the satisfaction of shift work; cardiovascular disorders and marital status and occupation; digestive disorders and the work schedules; sleep disorders and the satisfaction of shift work; musculoskeletal disorders, cardiovascular disorders and sleep disorders and age, job experience and shift work experience. And finally, there were significant associations among sleep disorders and age, job experience and the shift work experience. Conclusion: Based on the findings of this study, demographic characteristics such as age, marital

    2002-04-01

    Inverse problems have recently drawn considerable attention from the physics community due to of potential widespread applications [K. Chadan and P. C. Sabatier, Inverse Problems in Quantum Scattering Theory, 2nd ed. (Springer Verlag, Berlin, 1989)]. An inverse emissivity problem that determines the emissivity g(nu) from measurements of only the total radiated power J(T) has recently been studied [Tao Wen, DengMing Ming, Xianxi Dai, Jixin Dai, and William E. Evenson, Phys. Rev. E 63, 045601(R) (2001)]. In this paper, a new type of generalized emissivity and transmissivity inverse (GETI) problem is proposed. The present problem differs from our previous work on inverse problems by allowing the unknown (emissivity) function g(nu) to be temperature dependent as well as frequency dependent. Based on published experimental information, we have developed an exact solution formula for this GETI problem. A universal function set suggested for numerical calculation is shown to be robust, making this inversion method practical and convenient for realistic calculations.

    The major problems facing medical entomology as a science and practical health care facilities in the Russian Federations allows to outline the tasks to be solved in order of their priority and significance. These include the study and monitoring of tick-borne infections, resurrecting malaria, gnat-induced diseases, acariases, allergosis and pediculosis. It is emphasized that medical entomology as a science cannot develop since the man-made changes of the environment and the predicted global warming of the Earth climate are not taken into account. The present status of medical entomological service is considered to be poor. Governmental support is required.

  9. Depression in Medical Disorders: Diagnostic Problems

    Full Text Available Depressive symptoms are very common among referrals to general hospital and comprise the most frequent cause for psychiatric consultation. Comorbidity of medical and psychiatric disorders are common among uneducated, unemployed people with low income. These conditions make it difficult to recognize and treat such patient group. The prevalence of medical disorders increase when there is a difficulty in reaching health services. The depressive mood may decrease the person’s willingness to access health service. Additionally, the problems in most of the people seeking for medical help are not recognized by the health providers. It is quiet difficult to diagnose depression in patients with medical disorders. Being sick, being in an hospital, inability to work, loss of functionality lead to a change in social roles which may cause mourning-like symptoms, symptoms quite similar to depression’s. Besides, vegetative and somatic symptoms used for the diagnosis of depression can be direct consequences of the medical disorder itself. Thus such phenomenological signs and symptoms are suggested not to be considered as sufficient criteria for a diagnosis of depression among patients with medical disorder. This diagnostic complexity is also reflected in the studies searching for depression prevalence in medical disorders. For instance, the prevalence of depression ranges between 0% to 100% among renal patients. The physical signs and symptoms of medical conditions can overlap with the symptoms of depression and this overlap stands as one of the major diagnostic challenge for researchers. There are several other reasons that might explain the discrepancies in depression prevalence among patients with medical disorders such as changes in diagnostic criteria over time, use of different diagnostic scales for depression, and studying the prevalence of depression in non-standardized populations. Depression prevalence is affected from demographic variables, type

    2010-01-01

    Neural networks (NNs) have been successfully applied to solve a variety of application problems involving classification and function approximation. Although backpropagation NNs generally predict better than decision trees do for pattern classification problems, they are often regarded as black boxes, i.e., their predictions cannot be explained as those of decision trees. In many applications, it is desirable to extract knowledge from trained NNs for the users to gain a better understanding of how the networks solve the problems. An algorithm is proposed and implemented to extract symbolic rules for medical diagnosis problem. Empirical study on three benchmarks classification problems, such as breast cancer, diabetes, and lenses demonstrates that the proposed algorithm generates high quality rules from NNs comparable with other methods in terms of number of rules, average number of conditions for a rule, and predictive accuracy.

    Kleiman, Howard

    2011-01-01

    This is concerned with essentially two ways in which to construct algorithms for obtaining both approximate and exact solutions to the general traveling salesman problem (GTSP)(the triangle equality need not be satisfied). The first uses an arbitrary n-cycle to permute the columns of an n X n matrix with weighted entries. In doing so, we obtain negative entries. Using these entries, we from negative cycles. We give a formula for the length of cycles necessary to obtain an n-cycle by patching. Using patching of negative cycles, we obtain an n-cycle. The second portion of the algorithm gives procedures for obtain an exact solution to the GTSP. Our second algorithm uses the average arc-value (aav) of a path. We first obtain an n-cycle in a manner similar to that in the first algorithm. Call this T_UPPERBOUND. We then construct paths each of which has an aav less than that of T_UPPERBOUND. Using parallel programming, we construct all paths whose values are less than that of T_UPPERBOUND. Then either we obtain an ...

    Describing the pattern of disease encountered in primary health care (PHC) in Ghana and the facilities available to treat it, this discussion provides an account of the rapidly deteriorating economic situation and its effects on the inhabitants and on medical practice. During the 1977-79 period Ghana suffered severe economic and political difficulties, affecting work at the University Hospital in Legon, Ghana. The workload differs from that in developed countries in several ways: tropical diseases are common; the diseases of proverty are rife; diseases due to poor public health and an absence of some diseases, e.g., myocardial infarct and multiple sclerosis. There is no equivalent of the British general practioner, but there are 4 main sources of care: 54 government hospitals with 137 health centrs and health posts distributed around the country; 57 private but relatively low cost hospitals and clinics; exclusive, high cost private clinics; and traditional healers and herbalists practicing their art. Between 1976-79 the economy of Ghana went into a steep decline. Exact figures for inflation are difficult to come by; 15% per year was popularly quoted. The cedi (the Ghanaian unit of currency) was officially devalued. Goods became very scarce as well as expensive. Basic food items, spare parts for vehicles and other machinery, petroleum products, soap, and all medical supplies were hard to obtain. There was public unrest during this period. Strikes became frequent. Notable from the health perspective was a strike of all professionals, including doctors, in June 1977, strikes of government employed nurses in April 1978 and May 1979. The main events were 3 changes of government. Although exact data are not easy to obtain, the diseases of poverty appeared to be on the increase. Lack of money tended to keep those not entitled to free treatment away from private hospitals, but the deteriorating situation at the clinics seemed to more than compensate for this. Shortages

  19. Generalization of Helmholtz coil problem

    Directory of Open Access Journals (Sweden)

    Petković Dejan M.

    2015-01-01

    Full Text Available The primary intent of this work is to propose a simple analytical method for designing coil systems for homogeneous and gradient magnetostatic field generation. Coil system consists of two identical coaxial (regular polygonal current loops. In the space between the loops, there is nearly homogeneous or nearly linear distribution of the magnetic field along the axes depending on the currents' direction. First, we derived a suitable, simple and general expression for the magnetic field along the axes due to a polygonal current loop. We emphasize the importance of the role of this expression for further analysis. The total on-axes magnetic field is the result of superposition of the magnetic fields that each loop generates separately. The proper distance between the loops and the current orientation make the system to become either Helmholtz coil or anti-Helmholtz coil. In this paper we give exact, analytical and general expression for this optimal distance that provides the magnetic field to be homogeneous (linear as much as possible. We based our study on Taylor series expansion of the total magnetic field, demanding that the first contaminating term must be canceled, in both, symmetric and asymmetric case.

    Awerbuch, B.; Azar, Y.; Bartal, Y. [Tel Aviv Univ. (Israel)

    1996-12-31

    The Generalized Steiner Problem (GSP) is defined as follows. We are given a graph with non-negative weights and a set of pairs of vertices. The algorithm has to construct minimum weight subgraph such that the two nodes of each pair are connected by a path. We consider the on-line generalized Steiner problem, in which pairs of vertices arrive on-line and are needed to be connected immediately. We give a simple O(log{sup 2} n) competitive deterministic on-line algorithm. The previous best online algorithm (by Westbrook and Yan) was O({radical}n log n) competitive. We also consider the network connectivity leasing problem which is a generalization of the GSP. Here edges of the graph can be either bought or leased for different costs. We provide simple randomized O(log{sup 2} n) competitive algorithm based on the on-line generalized Steiner problem result.

    The prevalence of medical marijuana diversion among adolescents in substance treatment and the relationship between medical marijuana diversion and marijuana attitudes, availability, peer disapproval, frequency of use and substance-related problems are not known. 80 adolescents (15-19 years) in outpatient substance treatment in Denver, Colorado, completed an anonymous questionnaire developed for the study and the Drug Use Screening Inventory-Revised (DUSI-R). The proportion ever obtaining marijuana from someone with a medical marijuana license was calculated. Those ever obtaining marijuana from someone with a medical marijuana license were compared to those never obtaining medical marijuana with respect to marijuana attitudes, availability, peer disapproval, frequency of use, DUSI-R substance use problem and overall problem score using Chi-Square analyses and independent t-tests. 39 (48.8%) reported ever obtaining marijuana from someone with a medical marijuana license. A significantly greater proportion of those reporting medical marijuana diversion, compared to those who did not, reported very easy marijuana availability, no friend disapproval of regular marijuana use and greater than 20 times of marijuana use per month over the last year. The diversion group compared to the no diversion group also reported more substance use problems and overall problems on the DUSI-R. Diversion of medical marijuana is common among adolescents in substance treatment. These data support a relationship between medical marijuana exposure and marijuana availability, social norms, frequency of use, substance-related problems and general problems among teens in substance treatment. Adolescent substance treatment should address the impact of medical marijuana on treatment outcomes. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

  11. Set Covering Problems with General Objective Functions

    CERN Document Server

    Cardinal, Jean

    2008-01-01

    We introduce a parameterized version of set cover that generalizes several previously studied problems. Given a ground set V and a collection of subsets S_i of V, a feasible solution is a partition of V such that each subset of the partition is included in one of the S_i. The problem involves maximizing the mean subset size of the partition, where the mean is the generalized mean of parameter p, taken over the elements. For p=-1, the problem is equivalent to the classical minimum set cover problem. For p=0, it is equivalent to the minimum entropy set cover problem, introduced by Halperin and Karp. For p=1, the problem includes the maximum-edge clique partition problem as a special case. We prove that the greedy algorithm simultaneously approximates the problem within a factor of (p+1)^1/p for any p in R^+, and that this is the best possible unless P=NP. These results both generalize and simplify previous results for special cases. We also consider the corresponding graph coloring problem, and prove several tr...

    In this paper we first consider the existence and the general form of solution to the following generalized inverse eigenvalue problem(GIEP) : given a set of n-dimension complex vectors { xj }jm = 1 and a set of complex numbers { λj} jm = 1, find two n × n centrohermitian matrices A, B such that { xj }jm = 1 and { λj }jm= 1 are the generalized eigenvectors and generalized eigenvalues of Ax = λBx, respectively. We then discuss the optimal approximation problem for the GIEP. More concretely, given two arbitrary matrices, A-, B- ∈Cn×n , we find two matrices A* and B* such that the matrix (A* ,B* ) is closest to (A- ,B-) in the Frobenius norm, where the matrix (A*, B* ) is the solution to the GIEP. We show that the expression of the solution of the optimal approximation is unique and derive the expression for it.

    The artificial neural network (ANN)–a machine learning technique inspired by the human neuronal synapse system–was introduced in the 1950s. However, the ANN was previously limited in its ability to solve actual problems, due to the vanishing gradient and overfitting problems with training of deep architecture, lack of computing power, and primarily the absence of sufficient data to train the computer system. Interest in this concept has lately resurfaced, due to the availability of big data, enhanced computing power with the current graphics processing units, and novel algorithms to train the deep neural network. Recent studies on this technology suggest its potentially to perform better than humans in some visual and auditory recognition tasks, which may portend its applications in medicine and healthcare, especially in medical imaging, in the foreseeable future.

    2008-03-01

    Medical informed consent is essential to the physician's ability to diagnose and treat patients as well as the patient's right to accept or reject clinical evaluation, treatment, or both. Medical informed consent should be an exchange of ideas that buttresses the patient-physician relationship. The consent process should be the foundation of the fiduciary relationship between a patient and a physician. Physicians must recognize that informed medical choice is an educational process and has the potential to affect the patient-physician alliance to their mutual benefit. Physicians must give patients equality in the covenant by educating them to make informed choices. When physicians and patients take medical informed consent seriously, the patient-physician relationship becomes a true partnership with shared decision-making authority and responsibility for outcomes. Physicians need to understand informed medical consent from an ethical foundation, as codified by statutory law in many states, and from a generalized common-law perspective requiring medical practice consistent with the standard of care. It is fundamental to the patient-physician relationship that each partner understands and accepts the degree of autonomy the patient desires in the decision-making process.

  7. From cases to projects in problem-based medical education

    2014-06-01

    Full Text Available Problem-based learning (PBL based on patient cases has become a well-established worldwide educational approach in medical education. Recent studies indicate that case-based PBL when used throughout an entire curriculum may develop into a counter-productive routine for students as well as teachers. Consequently, there is a need to develop PBL approaches further allowing students to work with more ill-defined problems and alternative learning structures. In this paper, we argue that this can be realised by introducing project-PBL into the medical curriculum, as in the medical education at Aalborg University, Denmark. We outline organisations of case- and project- PBL in the medical curriculum and present an explorative study of 116 first and second year students’ experiences working in the two settings of PBL. Results reveal that students generally rate their PBL experiences positively however, project-PBL is rated more positively than case-PBL on all parameters studied. These results invite further consideration of the differences in working with cases and projects. Two central differences are discussed; the nature of the problem as the trigger of learning and students' possibilities for directing their own learning processes. The study demonstrates that introducing project-PBL may contribute significantly in problem-based medical education. However, the need for extensive research into advantages and limitations of the combined use of case- and project-PBL is also emphasised.

    2014-01-01

    Full Text Available Medical schools are committed to both students and society to develop capabilities required to succeed in health care environments. Present diagnosis and treatment methods become obsolete faster, demanding that medical schools incorporate competency-based education to keep pace with future demands. This study was conducted to assess the problem solving disposition of medical students. A three-subcategory model of the skill is proposed. The instrument was validated on content by a group of 17 experts in medical education and applied to 135 registered students on the sixth year of the M.D. Physician Surgeon program at a private medical school. Cronbach’s alpha indicated an internal consistency of 0.751. The findings suggest that selected items have both homogeneity and validity. The factor analysis resulted in components that were associated with three problem-solving subcategories. The students’ perceptions are higher in the pattern recognition and application of general strategies for problem solving subcategories of the Problem solving disposition model.

    We consider the following geometric alignment problem: Given a set of line segments in the plane, find a convex region of smallest area that contains a translate of each input segment. This can be seen as a generalization of Kakeya\\'s problem of finding a convex region of smallest area such that a needle can be turned through 360 degrees within this region. Our main result is an optimal Θ(n log n)-time algorithm for our geometric alignment problem, when the input is a set of n line segments. We also show that, if the goal is to minimize the perimeter of the region instead of its area, then the optimum placement is when the midpoints of the segments coincide. Finally, we show that for any compact convex figure G, the smallest enclosing disk of G is a smallest-perimeter region containing a translate of any rotated copy of G. © 2012 Springer-Verlag Berlin Heidelberg.

    2003-01-01

    We solve the boson normal ordering problem for F[(a*)^r a^s], with r,s positive integers, where a* and a are boson creation and annihilation operators satisfying [a,a*]=1. That is, we provide exact and explicit expressions for the normal form wherein all a's are to the right. The solution involves integer sequences of numbers which are generalizations of the conventional Bell and Stirling numbers whose values they assume for r=s=1. A comprehensive theory of such generalized combinatorial numbers is given including closed-form expressions (extended Dobinski-type formulas)and generating functions. These last are special expectation values in boson coherent states.

  14. Solution of the Generalized Noah's Ark Problem.

    Billionnet, Alain

    2013-01-01

    The phylogenetic diversity (PD) of a set of species is a measure of the evolutionary distance among the species in the collection, based on a phylogenetic tree. Such a tree is composed of a root, internal nodes, and leaves that correspond to the set of taxa under study. With each edge of the tree is associated a non-negative branch length (evolutionary distance). If a particular survival probability is associated with each taxon, the PD measure becomes the expected PD measure. In the Noah's Ark Problem (NAP) introduced by Weitzman (1998), these survival probabilities can be increased at some cost. The problem is to determine how best to allocate a limited amount of resources to maximize the expected PD of the considered species. It is easy to formulate the NAP as a (difficult) nonlinear 0-1 programming problem. The aim of this article is to show that a general version of the NAP (GNAP) can be solved simply and efficiently with any set of edge weights and any set of survival probabilities by using standard mixed-integer linear programming software. The crucial point to move from a nonlinear program in binary variables to a mixed-integer linear program, is to approximate the logarithmic function by the lower envelope of a set of tangents to the curve. Solving the obtained mixed-integer linear program provides not only a near-optimal solution but also an upper bound on the value of the optimal solution. We also applied this approach to a generalization of the nature reserve problem (GNRP) that consists of selecting a set of regions to be conserved so that the expected PD of the set of species present in these regions is maximized. In this case, the survival probabilities of different taxa are not independent of each other. Computational results are presented to illustrate potentialities of the approach. Near-optimal solutions with hypothetical phylogenetic trees comprising about 4000 taxa are obtained in a few seconds or minutes of computing time for the GNAP, and in

    2016-07-01

    We consider the well-known problem of the forward computation of the gradient of the gravitational potential generated by a mass density distribution of general 3D geometry. Many methods have been developed for given geometries, and the computation time often appears as a limiting practical issue for considering large or complex problems. In this work, we develop a fast method to carry out this computation, where a tetrahedral mesh is used to model the mass density distribution. Depending on the close- or long-range nature of the involved interactions, the algorithm automatically switches between analytic integration formulae and numerical quadratic formulae, and relies on the Fast Multipole Method to drastically increase the computation speed of the long-range interactions. The parameters of the algorithm are empirically chosen for the computations to be the fastest possible while guarantying a given relative accuracy of the result. Computations that would load many-core clusters for days can now be carried out on a desk computer in minutes. The computation of the contribution of topographical masses to the Earth's gravitational field at the altitude of the GOCE satellite and over France are proposed as numerical illustrations of the method.

In such problems, clusters instead of nodes have to be interconnected by a network. The network interconnecting the clusters...... is a fixed-charge network, and thus the GFCND problem generalizes the fixed-charge network design problem. The GFCND problem is related to the more general problem of designing hierarchical telecommunication networks. A mixed integer programming model is described and a branch-cut-and-price algorithm...

    Given a set of line segments in the plane, not necessarily finite, what is a convex region of smallest area that contains a translate of each input segment? This question can be seen as a generalization of Kakeya\\'s problem of finding a convex region of smallest area such that a needle can be rotated through 360 degrees within this region. We show that there is always an optimal region that is a triangle, and we give an optimal Θ(nlogn)-time algorithm to compute such a triangle for a given set of n segments. We also show that, if the goal is to minimize the perimeter of the region instead of its area, then placing the segments with their midpoint at the origin and taking their convex hull results in an optimal solution. Finally, we show that for any compact convex figure G, the smallest enclosing disk of G is a smallest-perimeter region containing a translate of every rotated copy of G. © 2013 Springer Science+Business Media New York.

    For each simple euclidean Jordan algebra V of rank ρ and degree δ, we introduce a family of classical dynamic problems. These dynamical problems all share the characteristic features of the Kepler problem for planetary motions, such as the existence of Laplace-Runge-Lenz vector and hidden symmetry. After suitable quantizations, a family of quantum dynamic problems, parametrized by the nontrivial Wallach parameter ν, is obtained. Here, ν in {W}(V):=[ k δ/2mid k=1, ldots, (ρ -1)] \\cup ((ρ -1)δ / 2, infty ) and was introduced by N. Wallach to parametrize the set of nontrivial scalar-type unitary lowest weight representations of the conformal group of V. For the quantum dynamic problem labelled by ν, the bound state spectra is -1/2/ (I+ν frac{ρ { 2})^2}, I = 0, 1, … and its Hilbert space of bound states gives a new realization for the afore-mentioned representation labelled by ν. A few results in the literature about these representations become more explicit and more refined. The Lagrangian for a classical Kepler-type dynamic problem introduced here is still of the simple form: 1/ 2 Vert dot{x}Vert ^2+1/ r. Here, dot{x} is the velocity of a unit-mass particle moving on the space consisting of V's semi-positive elements of a fixed rank, and r is the inner product of x with the identity element of V.

In four experiments, school students were required to learn about a topic through practice with a general problem-solving strategy, through a conventional problem solving strategy or by studying worked examples. In Experiments 1 and 2 using junior high school students learning geometry, low knowledge students in the general problem-solving group scored significantly higher on near or far transfer tests than the conventional problem-solving group. In Experiment 3, an advantage for a general problem-solving group over a group presented worked examples was obtained on far transfer tests using the same curriculum materials, again presented to junior high school students. No differences between conditions were found in Experiments 1, 2, or 3 using test problems similar to the acquisition problems. Experiment 4 used senior high school students studying economics and found the general problem-solving group scored significantly higher than the conventional problem-solving group on both similar and transfer tests. It was concluded that the general problem-solving strategy was helpful for novices, but not for students that had access to domain-specific knowledge.

    2013-01-01

    Full Text Available This paper investigates the scheduling problems with general deterioration models. By the deterioration models, the actual processing time functions of jobs depend not only on the scheduled position in the job sequence but also on the total weighted normal processing times of the jobs already processed. In this paper, the objective is to minimize the makespan. For the single-machine scheduling problems with general deterioration effects, we show that the considered problems are polynomially solvable. For the flow shop scheduling problems with general deterioration effects, we also show that the problems can be optimally solved in polynomial time under the proposed conditions.

    In contrast to factual knowledge the reasoning processes of doctors in their attempts to clarify the patient's problem has been a somewhat neglected domain of study. The rise of experimental psychology, clinical decision analysis, and problem-based learning fostered studies in this area. Several studies from different viewpoints have been performed, leading to a more profound understanding of these processes. I approached the issue from a general physician viewpoint which reverted to the old distinction between deductive and inductive reasoning. Within a group of 68 participating doctors (family doctors and general physicians) the inductive method was exclusively employed. From this finding we conjecture that the inductive type of reasoning is the predominant style in the medical world. The consequences as attached to the overall utilization of the inductive method are far-reaching. Among others, process retracing as a feedback mechanism fails to function when it results from the intuitive nature of the (pattern-recognition) process. As a consequence we do not and can not know what we may learn from experience, good things as well as bad things. The inductive method is a method of practice and quick reaction, but it leaves us empty-handed as far as understanding and teaching are concerned.

    A study was conducted among out-patients attending the Melaka Tengah Health Clinic to determine their compliance status towards antihypertensive, antidiabetic and antiasthmatic drugs. A total of 585 patients were enrolled in this study. Assessment of compliance was carried out using pill-counting and house-to-house interviews 14 days from the date of medication dispensed at the counter. The noncompliance rate among the 464 successfully interviewed patients was 56%. The mean noncompliance percentage was 78.0 +/- 43.1% (range: -10.0-314.3%). Among the four variables of compliance studied, race was not seen as a determinant of compliance. The older age group and those taking two or more drugs were statistically significant to be a noncomplier. Females were highly likely not to comply with drug therapy. Patients who conform to their refill dates were not really drug compliers. Forgetting to take their drugs and inability to read instructions on drug labels were the main reasons given. Underdosing was more common than overdosing, with an estimated cost of RM20,261.00 of unused medications per year.

    A 43 year-old diabetic woman, who suffered chronic cough and brown expectoration, is presented in this clinical problem. X-ray exam and CT thorax scan showed a cavitary lung lesion, located at the upper field of the left lung. This lesion had 5 cm in diameter, with a thick wall and a spherical shadow inside. The diagnosis of chronic cavitary pulmonary coccidioidomycosis was based on the isolation of Coccidioides sp. from cultures of expectoration and bronchoalveolar lavage, and the detection of specific antibodies in immunodiffusion test and counterimmunoelectrophoresis with coccidiodin. Her diabetes was not well controlled. She was treated with intravenous amphotericin B and oral itraconazole, with good clinical response; after four months of treatment the patient abandoned clinical controls. We suppose that the patient presented a coccidioidal fungus ball, inside a chronic cavitary lesion due to pulmonary coccidiodomycosis. She came from an endemic zone of coccidioidomycosis in the Northwest of the Argentine Republic (Catamarca Province).

  4. Medical aspects of the hazardous waste problem

    Ozonoff, D.

    1982-12-01

    Although no one knows exactly how much toxic material continues to be released into our environment, most observers believe the amount is substantial. In the last few years, in the state of Massachusetts alone, 22 communities have had their municipal water supplies seriously compromised by chemical contamination, causing alarm and dismay among water users. Nation-wide, public concern has reached the point that in some opinion polls, hazardous waste ranks second only behind inflation as a cause of serious worry. Despite widespread anxiety, shared by public health officials, few studies have shown conclusive evidence of health consequences from toxic materials in the environment. Even in the case of such gross contamination as in the Love Canal area of Niagara Falls, New York, health effects have been difficult to establish. This is partly due to intrusion of the adversary process in cases where liability is involved; it is also a result, however, of inherent technical problems that plague any determination of health hazard. This paper reviews some of these problems, considers some current risk assessment approaches, and touches on medicolegal and regulatory aspects of the hazardous waste problem.

    Current undergraduate medical education is criticized for not preparing physicians to be independent thinkers. The rapid development of new imaging techniques and the problem of escalating medical costs call for efficient patient management. The development of algorithms in imaging work-up of patient problems is an excellent example of problem solving or medical decision making. The senior elective in radiology at our institution incorporates this type of problem-solving session. Small groups (15-25 students) with faculty guidance discuss 5-6 common patient problems to develop an investigative plan in imaging. Algorithms are thus developed by the group, but not presented for memorization. Small changes are then made in the case history so that the students are forced to make new hypotheses and generate a modified algorithm. Correlative costs are included. Flexibility and initiative in development of patient management algorithms are stressed.

    2006-05-01

    The solution of an optimization problem through the continuous Hopfield network (CHN) is based on some energy or Lyapunov function, which decreases as the system evolves until a local minimum value is attained. A new energy function is proposed in this paper so that any 0-1 linear constrains programming with quadratic objective function can be solved. This problem, denoted as the generalized quadratic knapsack problem (GQKP), includes as particular cases well-known problems such as the traveling salesman problem (TSP) and the quadratic assignment problem (QAP). This new energy function generalizes those proposed by other authors. Through this energy function, any GQKP can be solved with an appropriate parameter setting procedure, which is detailed in this paper. As a particular case, and in order to test this generalized energy function, some computational experiments solving the traveling salesman problem are also included.

In all the Asian countries governments supported the initiatives of the expert and entrepreneur community, and invested heavily in its development. Bangladesh has got great potential in developing biotechnology and reaping its fruits. However, lack of commitment and patriotism, and too much corruption and irresponsibility in political and bureaucratic establishment are the major hindrance to the development of biotechnology in Bangladesh.

    2008-01-01

    Generalized chromosome genetic algorithm (GCGA) was proposed for solving generalized traveling salesman problems (GTSP) as reported in the authors' earlier work. Theoretically, the GCGA could also be used to solve the classical traveling salesman problem (CTSP), which has not been reported by others. In this paper, the generalized chromosome characteristics are analyzed and the feasibility for consistently solving the GTSP and CTSP is verified. Numerical experiments show the advantages of the GCGA for solving a large-scale CTSP.

    Full Text Available Purpose: The aim of this study was to evaluate medical students' social problem solving and coping skills. Material and Methods: In this correlational descriptive study, data were gathered from 457 medical students. Social Problem Solving Inventory and Social Problem Coping Behaviours Inventory were used. Results: The most preferred activities when the students face a problem were talking with friends (87.1%, talking with special persons (85.4%, sleeping (82.6%, talking with family members (81.6%, and eating (79.8%. The ratio of the behaviors that can be deemed risky were exhibiting aggressive and violent behaviors (18.9%, drinking alcohol (18.7%, smoking (17.6%, playing games of chance (16.9%, and using substance (3.8%. There was a positive relationship between total scores of Social Problem Solving Inventory and Social Problem Coping Behaviours Inventory. It is found that immature social problem solving ability has increased the risk of unfavourable behaviours by 3.1 fold. Conclusion: Social problem solving ability is significantly correlated with coping behaviours and may predict it. Medical students who are the doctors and the role models of the future need to develop their social problem solving skills in addition to clinical problem solving skills.

    Full Text Available One of the most acute problems in the healthcare industry – the problem of the quality of medical services. In this area, there is no established definition of medical services or approaches to quality management. The aim of the article is to analyze the existing definitions of “quality of medical services,” as well as development approach to managing medical organization. At the same time the management of the medical organization should be focused on ensuring the quality as the most important criterion for the organization. Methodology of the study is based on analysis and grouping of existing definitions of medical services, the factorial approach to evaluating the quality and organization of the process approach to management of the medical organization. Noting the versatility and diversity concepts of quality of care the authors suggest grouping of direct and indirect factors affecting the quality of medical services. However, it is important, according to the authors, to move from functional management to management based on the process approach, which provides better control over the processes of customer service.

    Forty-six medical and dental journals are published from Pakistan of which only 29 are currently recognized by the Pakistan Medical and Dental Council. Only a few are peer reviewed. Six are indexed in Medline while EMBASE Excerpta Medica and World Health Organization Index Medicus for Eastern Mediterranean Region cover others. Editors of the peer reviewed medical journals are faced with numerous problems, which relate to the authors. Some of these are: shortage of quality of manuscripts, poor quality of reviewers, problems with indexation in international indexing services particularly Medline, duplicate submission and authorship and lastly, financial problems. Patronage from the Pharma industry is the major source of revenue which itself has serious implications. Editing a medical journal is a very stressful job and the editors have to work under too many pressures. A lot of useful data is presented at medical conferences, but a vast majority of it remains unpublished for various reasons, which adversely affects the citation rate from scientists from the developing third world countries in the world of medical literature. A few lectures on medical writing and research methodology to final year medical students will expose them to the art of medical writing. Specialty organizations can be persuaded to have a session on medical writing at their conferences, which will be extremely helpful not only to the potential new authors but also others, thereby improving the quality of their manuscripts. In addition to regular seminars, workshops for authors, reviewers and training courses for editors, subscribing to local medical journals by healthcare professionals and libraries are some of the measures that will help improve the situation to a great extent.

    Lian, Lian; Castelain, Emmanuel

    2010-06-01

    This paper presents a new distribution and route planning problem, General Delivery Problem (GDP) which is more general than the well-known Vehicle Routing Problem. To solve a GDP, a three-phase framework heuristic approach based on decomposition techniques is introduced. The decomposition techniques are employed to divide an original problem into a set of sub-problems, which can reduce the problem size. A kind of decomposition technique, Capacity Clustering Algorithm (CCA), is embedded into the framework with Simulated Annealing (SA) to solve a special GDP. The proposed three-phase framework with the above two algorithms is compared with five other decomposition methods in a distribution instance of the Regional Fire and Emergency Center in the north of France.

    In this paper we introduce the concept of generalized d-graph (admitting cycles) as special dependency-graphs for modelling dynamic programming (DP) problems. We describe the d-graph versions of three famous single-source shortest algorithms (The algorithm based on the topological order of the vertices, Dijkstra algorithm and Bellman-Ford algorithm), which can be viewed as general DP strategies in the case of three different class of optimization problems. The new modelling method also makes possible to classify DP problems and the corresponding DP strategies in term of graph theory.

    We give a general monotonicity formula for local minimizers of free discontinuity problems which have a critical deviation from minimality, of order d - 1. This result allows us to prove partial regularity results (that is closure and density estimates for the jump set) for a large class of free discontinuity problems involving general energies associated to the jump set, as for example free boundary problems with Robin conditions. In particular, we give a short proof to the De Giorgi-Carriero-Leaci result for the Mumford-Shah functional.

    2017-03-01

    To describe general practitioners' experiences of being the principal physician responsible for a nursing home. Fifteen general practitioners assigned to a nursing home participated in semi-structured qualitative interviews. Data were analysed using systematic text condensation. Medical assessment is the main duty of general practitioners. Advance care planning together with residents and family members facilitates future decisions on medical treatment and end-of-life care. Registered Nurses' continuity and competence are perceived as crucial to the quality of care, but inadequate staffing, lack of medical equipment and less-than-optimal IT systems for electronic healthcare records are impediments to patient safety. The study highlights the importance of advance care planning together with residents and family members in facilitating future decisions on medical treatment and end-of-life care. To meet the increasing demands for more complex medical treatment at nursing homes and to provide high-quality palliative care, there would seem to be a need to increase Registered Nurses' staffing and acquire more advanced medical equipment, as well as to create better possibilities for Registered Nurses and general practitioners to access each other's healthcare record systems. © 2016 Nordic College of Caring Science.

    We develop a theory for stochastic control problems which, in various ways, are time inconsistent in the sense that they do not admit a Bellman optimality principle. We attach these problems by viewing them within a game theoretic framework, and we look for Nash subgame perfect equilibrium points...... examples of time inconsistency in the literature are easily seen to be special cases of the present theory. We also prove that for every time inconsistent problem, there exists an associated time consistent problem such that the optimal control and the optimal value function for the consistent problem....... For a general controlled Markov process and a fairly general objective functional we derive an extension of the standard Hamilton-Jacobi-Bellman equation, in the form of a system of on-linear equations, for the determination for the equilibrium strategy as well as the equilibrium value function. All known...

    The generalized Nash equilibrium problem (GNEP) is a generalization of the standard Nash equilibrium problem (NEP),in which both the utility function and the strategy space of each player depend on the strategies chosen by all other players.This problem has been used to model various problems in applications.However,the convergent solution algorithms are extremely scare in the literature.In this paper,we present an incremental penalty method for the GNEP,and show that a solution of the GNEP can be found by solving a sequence of smooth NEPs.We then apply the semismooth Newton method with Armijo line search to solve latter problems and provide some results of numerical experiments to illustrate the proposed approach.

    Various applications of nanoscale science to the field of medicine have resulted in the ongoing development of the subfield of nanomedicine. Within the past several years, there has been a concurrent proliferation of academic journals, textbooks, and other professional literature addressing fundamental basic science research and seminal clinical developments in nanomedicine. Additionally, there is now broad consensus among medical researchers and practitioners that along with personalized medicine and regenerative medicine, nanomedicine is likely to revolutionize our definitions of what constitutes human disease and its treatment. In light of these developments, incorporation of key nanomedicine concepts into the general medical curriculum ought to be considered. Here, I offer for consideration five key nanomedicine concepts, along with suggestions regarding the manner in which they might be incorporated effectively into the general medical curriculum. Related curricular issues and implications for medical education also are presented.

    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. 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. 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). 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.

    2016-10-01

    The advent of smartphones has enabled a plethora of medical apps for disease management. As of 2012, there are 40,000 health care-related mobile apps available in the market. Since most of these medical apps do not go through any stringent quality assessment, there is a risk of consumers being misinformed or misled by unreliable information. In this regard, apps that target medication-related problems (MRPs) are not an exception. There is little information on what constitutes quality in apps that target MRPs and how good the existing apps are. To develop a quality assessment tool for evaluating apps that target MRPs and assess the quality of such apps available in the major mobile app stores (iTunes and Google Play). The top 100 free and paid apps in the medical categories of iTunes and Google Play stores (total of 400 apps) were screened for inclusion in the final analysis. English language apps that targeted MRPs were downloaded on test devices to evaluate their quality. Apps intended for clinicians, patients, or both were eligible for evaluation. The quality assessment tool consisted of 4 sections (appropriateness, reliability, usability, privacy), which determined the overall quality of the apps. Apps that fulfilled the inclusion criteria were classified based on the presence of any 1 or more of the 5 features considered important for apps targeting MRPs (monitoring, interaction checker, dose calculator, medication information, medication record). Descriptive statistics and Mann-Whitney tests were used for analysis. Final analysis was based on 59 apps that fulfilled the study inclusion criteria. Apps with interaction checker (66.9%) and monitoring features (54.8%) had the highest and lowest overall qualities. Paid apps generally scored higher for usability than free apps (P = 0.006) but lower for privacy (P = 0.003). Half of the interaction checker apps were unable to detect interactions with herbal medications. Blood pressure and heart rate monitoring apps

    Karapetyan, Daniel

    2010-01-01

    The Generalized Traveling Salesman Problem (GTSP) is a well-known combinatorial optimization problem with a host of applications. It is an extension of the Traveling Salesman Problem (TSP) where the set of cities is divided into so-called clusters, and the salesman have to visit each cluster exactly once. While GTSP is a very important combinatorial optimization problem and is well-studied in many aspects, researches still did not pay enough attention to GTSP specific local search and mostly use simple TSP heuristics with basic adaptations for GTSP\\@. This paper aims at thorough and deep investigation of the neighborhoods specific for GTSP and algorithms that can explore these neighborhoods quickly. We formalize the procedure of adaptation of a TSP neighborhood for GTSP and propose efficient algorithms to explore the obtained neighborhoods. We also generalize all other existing and some new GTSP neighborhoods. Apart from these theoretical results, we also provide the results of a thorough experimental analysi...

  4. A Parameterized Splitting Preconditioner for Generalized Saddle Point Problems

    Directory of Open Access Journals (Sweden)

    Wei-Hua Luo

    2013-01-01

    Full Text Available By using Sherman-Morrison-Woodbury formula, we introduce a preconditioner based on parameterized splitting idea for generalized saddle point problems which may be singular and nonsymmetric. By analyzing the eigenvalues of the preconditioned matrix, we find that when α is big enough, it has an eigenvalue at 1 with multiplicity at least n, and the remaining eigenvalues are all located in a unit circle centered at 1. Particularly, when the preconditioner is used in general saddle point problems, it guarantees eigenvalue at 1 with the same multiplicity, and the remaining eigenvalues will tend to 1 as the parameter α→0. Consequently, this can lead to a good convergence when some GMRES iterative methods are used in Krylov subspace. Numerical results of Stokes problems and Oseen problems are presented to illustrate the behavior of the preconditioner.

    Full Text Available Introduction: In traditional medical education systems much interest is placed on the cramming of basic and clinical facts without considering their applicability in the future professional career. The aim of this study is to evaluate a novice medical training method (problem-based learning as compared to the contemporary teacher-based medical education or traditional methods. Methods: Selection of the study subjects was done through simple sampling and according to the division of medical students introduced from Medical Faculty to the Pediatrics Department with no personal involvement. 120 medical students were assigned to 8 groups of 15 students each. For four months, 4 groups were trained with traditional method and 4 other groups underwent problem-based learning method on selected subject materials. In each method, a pre-course test at the beginning and a post-course test at the end of each course were given to each group. The questionnaire used in this study as the instrument was composed of 39 questions, 37 multiple choice questions and two short answer questions. Three professors of pediatric gastroenterologist took part in the training. Two of these professors were responsible for solving task training method. The third professor used traditional teacher-centered methodology to eliminate any possible bias. Scores obtained from these tests were analyzed using paired t-test and independent t-test. P values of less than 0.05 were considered as significant. Results: The scores of the students undergoing the traditional method were 14.70±3.03 and 21.20±4.07 in the first and second test, respectively. In problembased learning, the scores were 15.82±3.29 in the first and 27.52±4.72 in the second test. There was a significant difference between the mean scores of post-course exams of the two groups (p=0.001, while no significant difference was observed between the mean scores of pre-course exams of the groups (p=0.550. Conclusion: It may be

    The two-body problem in general relativity is reduced to the problem of an effective particle (with an energy-dependent relativistic reduced mass) in an external field. The effective potential is evaluated from the Born diagram of the linearized quantum theory of gravity. It reduces to a Schwarzschild-like potential with two different `Schwarzschild radii'. The results derived in a weak field approximation are expected to be relevant for relativistic velocities.

    Full Text Available Based on the smoothing function of penalized Fischer-Burmeister NCP-function, we propose a new smoothing inexact Newton algorithm with non-monotone line search for solving the generalized nonlinear complementarity problem. We view the smoothing parameter as an independent variable. Under suitable conditions, we show that any accumulation point of the generated sequence is a solution of the generalized nonlinear complementarity problem. We also establish the local superlinear (quadratic convergence of the proposed algorithm under the BD-regular assumption. Preliminary numerical experiments indicate the feasibility and efficiency of the proposed algorithm.

    Worldwide Family Medicine has gained an important place in the undergraduate medical curriculum over the last few decades and general practices have become training centers for students. Exposure to patients early in the disease process, out patient management of common problems, follow up of chronic diseases and psychosocial aspects of health and disease are educational advantages of community based training but such training could have varying impact on patients, students and trainers. This study explored the views of General Practitioner (GP) trainers on their experience in training students. This qualitative study was conducted among GP trainers of the faculty of medicine, University of Kelaniya, Sri Lanka, to explore their experience on wide range of issues related to their role as GP trainers. The interviews were recorded and transcribed verbatim. Themes expressed were identified. Altruistic reasons, self-satisfaction, self-esteem and opportunity to improve their knowledge were the motivations for their involvement in teaching. Teachers were confident of their clinical and teaching skills. They perceived that patients were willing participants of the process and benefited from it. There was a positive impact on consultation dynamics. Time pressure was the major problem and ideal number of trainees per session was two. They were willing to attend teacher training workshops to update their knowledge. GP trainers driven by altruistic reasons were willing participants of student training process. The perceived advantages of involvement of teaching for trainers and patients were an encouragement for potential trainers. University should organize training sessions for trainers which will boost their knowledge, confidence and teaching skills which will eventually benefit students.

    A general solution for programmed burn calculations of the light times produced by a singlepoint initiation of a single HE region surrounding an inert region has been developed. In contrast to the original solutions proposed in References 1 and 2, the detonator is no longer restricted to a location on a Cartesian axis and can be located at any point inside the HE region. This general solution has been implemented in the ExactPack suite of exact solvers for verification problems.

    The numerical renormalization group is used to solve quantum impurity problems, which describe magnetic impurities in metals, nanodevices, and correlated materials within dynamical mean field theory. Here we present a simple generalization of the Wilson chain, which improves the scaling of computational cost with the number of conduction bands, bringing more complex problems within reach. The method is applied to calculate the t matrix of the three-channel Kondo model at T =0, which shows universal crossovers near non-Fermi-liquid critical points. A nonintegrable three-impurity problem with three bands is also studied, revealing a rich phase diagram and novel screening and overscreening mechanisms.

    Focused on a variation of the euclidean traveling salesman problem (TSP), namely, the generalized traveling salesman problem (GTSP), this paper extends the ant colony optimization method from TSP to this field. By considering the group influence, an improved method is further improved. To avoid locking into local minima, a mutation process and a local searching technique are also introduced into this method. Numerical results show that the proposed method can deal with the GTSP problems fairly well, and the developed mutation process and local search technique are effective.

  13. Automatically Produced Algorithms for the Generalized Minimum Spanning Tree Problem

    Directory of Open Access Journals (Sweden)

    Carlos Contreras-Bolton

    2016-01-01

    Full Text Available The generalized minimum spanning tree problem consists of finding a minimum cost spanning tree in an undirected graph for which the vertices are divided into clusters. Such spanning tree includes only one vertex from each cluster. Despite the diverse practical applications for this problem, the NP-hardness continues to be a computational challenge. Good quality solutions for some instances of the problem have been found by combining specific heuristics or by including them within a metaheuristic. However studied combinations correspond to a subset of all possible combinations. In this study a technique based on a genotype-phenotype genetic algorithm to automatically construct new algorithms for the problem, which contain combinations of heuristics, is presented. The produced algorithms are competitive in terms of the quality of the solution obtained. This emerges from the comparison of the performance with problem-specific heuristics and with metaheuristic approaches.

  14. borealis - A generalized global update algorithm for Boolean optimization problems

    Zhu, Zheng; Katzgraber, Helmut G

    2016-01-01

    Optimization problems with Boolean variables that fall into the nondeterministic polynomial (NP) class are of fundamental importance in computer science, mathematics, physics and industrial applications. Most notably, solving constraint-satisfaction problems, which are related to spin-glass-like Hamiltonians in physics, remains a difficult numerical task. As such, there has been great interest in designing efficient heuristics to solve these computationally difficult problems. Inspired by parallel tempering Monte Carlo in conjunction with the rejection-free isoenergetic cluster algorithm developed for Ising spin glasses, we present a generalized global update optimization heuristic that can be applied to different NP-complete problems with Boolean variables. The global cluster updates allow for a wide-spread sampling of phase space, thus considerably speeding up optimization. By carefully tuning the pseudo-temperature (needed to randomize the configurations) of the problem, we show that the method can efficie...

    Musical education and the musical profession can be stressful, which may make musicians vulnerable for stress-related disorders. To determine if music students are particularly at risk for mental problems, we used the Standardised Assessment of Personality-Abbreviated Scale (SAPAS) and the Symptom Questionnaire (SQ48S) to compare symptoms in first-year conservatory students (n=33) and first-year medical students (n=43). On the SAPAS, we found that medical students have significantly more difficulty making and keeping friends (p=0.015). Also, we observed a trend that conservatory students lose their temper more easily (p=0.040). Both student groups showed high scores for the personality trait "perfectionism." On the SQ48, we observed a trend that both conservatory and medical students experience more psychological problems than the general population, but there were no significant differences between conservatory students and medical students in the total scores of both questionnaires.

    2007-03-01

    To examine medication-related problems from the perspective of patients with a chronic condition and to identify how they may be supported in managing their medication. Patients prescribed medication for cardiovascular disease were recruited through five general medical surgeries and four community pharmacies in south London. Data were collected in 98 face-to-face interviews in participants' own homes. Interviews were designed to enable a detailed and holistic exploration of medication-related problems from participants' perspectives. Data were audio-recorded and transcribed verbatim to allow qualitative analysis. Five broad categories of medication-related problem emerged which were examined in the context of patients' perspectives on, and experiences of, the use of medicines and health services. These were concerns about and management of side effects; differing views regarding the use of medicines; cognitive, practical and sensory problems; lack of information or understanding; and problems with access to, and organisation of, services. All categories of problem had potential implications for the success of therapy in that they created barriers to adherence, access to medication or informed decision-making. The study demonstrated how patients actively engage in decision-making about their medicines in the home, if not in the consultation. The five categories of problem provide a focus for interventions by health professionals to support patients in achieving optimal theory outcomes. They demonstrate the need for a comprehensive approach, spanning patient education to the systems of delivery of care. Within the NHS in Britain, policy and practice initiatives are being designed to achieve this end. Further research should focus on the evaluation of professional practices and service developments in supporting patients in the self-management of their medicines.

    Full Text Available Drug utilization in the in-patient setting can provide mechanisms to assess drug prescribing trends, efficiency and cost-effectiveness of hospital formularies and examine sub-populations such as children for which prescribing habits are different from adults. Objectives: The aim of this descriptive study was to analyze general medication utilization patterns and costs excluding antimicrobials prescriptions and to compare two pediatric admission units in a tertiary care university hospital. Methods: The total number of admitted children was 1,521 and 1,467 for the A and B admission units, respectively. The electronic data from 252 and 253 hospitalized children in the A and B admission unit were prospectively screened for general medication prescriptions, children on antimicrobials were excluded from the analysis. Their electronic charts were viewed once weekly from October 15, 2007 up to April 7, 2008 using the prescription-point prevalence method. One medication was considered to be one prescription. Results: The general medications prescription number was 790 for 94 children (8.4 prescription/patient in A and 959 for 88 children (10.9 prescription/patient in B (p=0.02. The general medications defined daily dose (DDD and drug utilization 90% (DU90% index were 2,509.63, 2,259 for A; and 6,110.35, 5,499 for B, respectively. The DU90% index placed salbutamol inhalation with 835 DDD and sodium heparin with 2,102 DDD in the first place for the A and B admission units, respectively. A net increment in medication cost was registered according to the calculated cost from the depicted DU90% when the A (20,263 NIS and B (6,269 NIS admission units were compared (p=0.04. Conclusions: A significant difference in the prescription utilization of general medications was shown between the A and B admission units. The A admission unit had lower prescriptions measured by the DU90% index with higher medication cost. Potential drug-drug interactions were depicted in

    2015-09-01

    Full Text Available This paper presents the application of Neutrosophic Set Theory (NST in solving Generalized Assignment Problem (GAP. GAP has been solved earlier under fuzzy environment. NST is a generalization of the concept of classical set, fuzzy set, interval-valued fuzzy set, intuitionistic fuzzy set. Elements of Neutrosophic set are characterized by a truth-membership function, falsity and also indeterminacy which is a more realistic way of expressing the parameters in real life problem. Here the elements of the cost matrix for the GAP are considered as neutrosophic elements which have not been considered earlier by any other author. The problem has been solved by evaluating score function matrix and then solving it by Extremum Difference Method (EDM [1] to get the optimal assignment. The method has been demonstrated by a suitable numerical example.

    In this paper the utility optimization problem for a general insurance model is studied. The reserve process of the insurance company is described by a stochastic differential equation driven by a Brownian motion and a Poisson random measure, representing the randomness from the financial market and the insurance claims, respectively. The random safety loading and stochastic interest rates are allowed in the model so that the reserve process is non-Markovian in general. The insurance company can manage the reserves through both portfolios of the investment and a reinsurance policy to optimize a certain utility function, defined in a generic way. The main feature of the problem lies in the intrinsic constraint on the part of reinsurance policy, which is only proportional to the claim-size instead of the current level of reserve, and hence it is quite different from the optimal investment/consumption problem with constraints in finance. Necessary and sufficient conditions for both well posedness and solvability...

  8. Polymorphic Uncertain Linear Programming for Generalized Production Planning Problems

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available A polymorphic uncertain linear programming (PULP model is constructed to formulate a class of generalized production planning problems. In accordance with the practical environment, some factors such as the consumption of raw material, the limitation of resource and the demand of product are incorporated into the model as parameters of interval and fuzzy subsets, respectively. Based on the theory of fuzzy interval program and the modified possibility degree for the order of interval numbers, a deterministic equivalent formulation for this model is derived such that a robust solution for the uncertain optimization problem is obtained. Case study indicates that the constructed model and the proposed solution are useful to search for an optimal production plan for the polymorphic uncertain generalized production planning problems.

    Medical language should be characterized by its precision, emotional neutrality and stability. The effective communication of results of scientific studies depends on compliance with current standards of drafting and style; texts with defects can hinder interest in the findings. In this study, we discuss some of the most common problems and errors in medical language, including the abuse of abbreviations and foreign words, the use of improper words, syntax errors and solecisms, the most common errors in titles and the abuse of capital letters and the gerund. Investigators have effective tools for dealing with these problems, such as quality texts, critical dictionaries of questions and difficulties with the Spanish language and various drafting and style manuals.

    2010-01-01

    Subclinical electroencephalogram discharges in children with psycho-cognitive problems are not uncommon. However, the clinical importance and relationship to cognitive deficits, as well as indications for medical treatment, are not well understood. Transient cognitive impairment, which accompanies electroencephalogram discharges, could negatively influence cognitive abilities over time. Studies have suggested that treatment with antiepileptic drugs normalizes electroencephalogram results, thereby preventing electrical paroxysmal discharges that could be harmful to the developing brain. Physicians should attempt to differentiate between corresponding factors, such as subtle seizures, nature of underlying etiology, stable cognitive deficits,seizure-inducing effects, and potential side effects of antiepileptic drugs prior to initiation of medical treatment for definitive diagnosis of transient cognitive impairment and its consequences. Therefore,appropriate criteria for patient selection and proper guidelines for medical therapy, should be addressed in future studies.

    Full Text Available Aldrin E Sweeney Center for Teaching & Learning, Ross University School of Medicine, Roseau, Commonwealth of Dominica Abstract: Various applications of nanoscale science to the field of medicine have resulted in the ongoing development of the subfield of nanomedicine. Within the past several years, there has been a concurrent proliferation of academic journals, textbooks, and other professional literature addressing fundamental basic science research and seminal clinical developments in nanomedicine. Additionally, there is now broad consensus among medical researchers and practitioners that along with personalized medicine and regenerative medicine, nanomedicine is likely to revolutionize our definitions of what constitutes human disease and its treatment. In light of these developments, incorporation of key nanomedicine concepts into the general medical curriculum ought to be considered. Here, I offer for consideration five key nanomedicine concepts, along with suggestions regarding the manner in which they might be incorporated effectively into the general medical curriculum. Related curricular issues and implications for medical education also are presented.

    2016-10-05

    Many children receive attention-deficit hyperactivity disorder (ADHD) medication, but factors that determine medication prescription are largely unknown. This study aimed to determine the relative impact of factors on the child, family and general practitioner (GP) practice level on ADHD medication prescription. We included 1259 Dutch children aged 6-18 years with a diagnostic code of ADHD or related behavioural problems (ICPC codes P20-P22) in NIVEL primary care database. Using multilevel analyses, we examined predictors of ADHD medication prescription. Children diagnosed as 'hyperactive' were 16 times more likely to be prescribed ADHD medication than those with 'behavioural concerns'. Children with a parent or sibling receiving ADHD medication were three to four times more likely to be prescribed ADHD medication themselves. Children from GP practices with a high percentage of children with ADHD were twice as likely to be prescribed ADHD medication. Concluding, factors on the individual, family and GP practice level determine ADHD medication prescription. Future research into the decision-making process for ADHD medication is warranted.

  16. A Generalized Multiscale Finite Element Method for Poroelasticity Problems I: Linear Problems

    Brown, Donald L

    2015-01-01

    In this paper, we consider the numerical solution of poroelasticity problems that are of Biot type and develop a general algorithm for solving coupled systems. We discuss the challenges associated with mechanics and flow problems in heterogeneous media. The two primary issues being the multiscale nature of the media and the solutions of the fluid and mechanics variables traditionally developed with separate grids and methods. For the numerical solution we develop and implement a Generalized Multiscale Finite Element Method (GMsFEM) that solves problem on a coarse grid by constructing local multiscale basis functions. The procedure begins with construction of multiscale bases for both displacement and pressure in each coarse block. Using a snapshot space and local spectral problems, we construct a basis of reduced dimension. Finally, after multiplying by a multiscale partitions of unity, the multiscale basis is constructed in the offline phase and the coarse grid problem then can be solved for arbitrary forcin...

    2016-07-01

    Patients presenting for appearance-related concerns are often perceived as being more difficult (ie, more needy, more difficult to satisfy) than patients presenting for medical dermatologic problems. While the reasons for this perception are many, some hypothesize that this may be related to a higher rate of anxiety, depression, or body image issues among these patients. To determine the prevalence of psychotropic medication use in cosmetic dermatology patients compared to the prevalence of such medication use in general dermatology patients. METHODS & The study was a retrospective chart review of female patients, 18 or older, new to a private practice. Exclusion criteria included dermatologic disorders with known psychosocial comorbidity. Psychotropic medication use was recorded. The percentage of subjects in the medical group (n=156) who reported using psychotropic medications was 22.2% compared to 26.8% in the cosmetic group (n=154; P=0.09). The prevalence of psychotropic medication use among all dermatology patients in our practice was relatively high, but there was no statistically significant difference in the rate of psychotropic medication use in cosmetic dermatology patients compared to general dermatology patients.

    2012-01-01

    Full Text Available Introduction. Mental health problems of adolescents are among the prevailing problems of public health. While studying for their future medical profession, the students of medicine have to exchange emotions with the patients intensively, and the empathic relationship itself bears a risk of eventual ”emotional depletion”, which leads to ”professional lack of emotions”. The study was aimed at presenting burnout syndrome as a challenge for mental health of medical students, its importance for the future professional engagement of doctors and the possibilities of its prevention. Methods. The authors of this paper review and analyze data and conclusions of previous national and international studies from this field and suggest possibilities of overcoming the condition of burnout. Results. The frequency of burnout syndrome, which is the synonym for the above mentioned condition of emotional exhaustion, is twice as high in medical professionals, particularly young ones, as in other professions on average. Burnout syndrome is nowadays regarded as a psychological distress experienced during the educational process and it has been observed in as many as 50% of medical students. The most significant factors independently associated with student burnout are: personality traits, stressful personal life events and learning and training conditions at their faculties. Conclusions. It is of utmost importance to understand the causes and consequences of psychological distress in students, and the faculties should not only identify these problems, but also endeavor to promote health by developing strategies for improving personal well-being, which are important for future doctors to achieve professional success and develop resistance to stress.

  20. Converting general nonlinear programming problems into separable programming problems with feedforward neural networks.

    Science.gov (United States)

    Lu, Bao-Liang; Ito, Koji

    2003-09-01

    In this paper we present a method for converting general nonlinear programming (NLP) problems into separable programming (SP) problems by using feedforward neural networks (FNNs). The basic idea behind the method is to use two useful features of FNNs: their ability to approximate arbitrary continuous nonlinear functions with a desired degree of accuracy and their ability to express nonlinear functions in terms of parameterized compositions of functions of single variables. According to these two features, any nonseparable objective functions and/or constraints in NLP problems can be approximately expressed as separable functions with FNNs. Therefore, any NLP problems can be converted into SP problems. The proposed method has three prominent features. (a) It is more general than existing transformation techniques; (b) it can be used to formulate optimization problems as SP problems even when their precise analytic objective function and/or constraints are unknown; (c) the SP problems obtained by the proposed method may highly facilitate the selection of grid points for piecewise linear approximation of nonlinear functions. We analyze the computational complexity of the proposed method and compare it with an existing transformation approach. We also present several examples to demonstrate the method and the performance of the simplex method with the restricted basis entry rule for solving SP problems.

    Here is presented a generalization of photogravitational restricted 3-bodies problem to the case of influence of Yarkovsky effect, which is known as reason of additional infinitesimal acceleration of a small bodies in the space (due to anisotropic re-emission of absorbed energy from the sun, other stellar sources). Asteroid is supposed to move under the influence of gravitational forces from 2 massive bodies (which are rotating around their common centre of masses on Kepler trajectories), as well under the influence of pressure of light from both the primaries. Analyzing the ODE system of motion, we explore the existense of equilibrium points for a small body (asteroid) in the case when the 2-nd primary is non-oblate spheroid. In such a case, it is proved the existence of maximally 256 different non-planar libration points in generalized photogravitational restricted 3-bodies problem when we take into consideration even a small Yarkovsky effect.

    We consider Einstein Gravity coupled to dynamical matter consisting of a gauge field with any compact gauge group and minimally coupled scalar fields. We investigate the conditions under which a free specification of a spatial field configuration for the total system and its derivative with respect to coordinate-time determines a solution to the field equations (generalized thin-sandwich problem). Sufficient conditions for local solvability (in the space of fields) are established.

    2010-01-01

    Background Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David Kolb, demonstrates the importance of individual learning styles in improving learning. This study helps elucidate the way in which medical students, surgical residents, and surgical faculty learn. Methods The Kolb Learning Style Inventory, which divides individual learning styles into Accommodating, Diverging, Converging, and Assimilating categories, was administered to the second year undergraduate medical students, general surgery resident body, and general surgery faculty at the University of Alberta. Results A total of 241 faculty, residents, and students were surveyed with an overall response rate of 73%. The predominant learning style of the medical students was assimilating and this was statistically significant (p < 0.03) from the converging learning style found in the residents and faculty. The predominant learning styles of the residents and faculty were convergent and accommodative, with no statistically significant differences between the residents and the faculty. Conclusions We conclude that medical students have a significantly different learning style from general surgical trainees and general surgeons. This has important implications in the education of general surgery residents. PMID:20591159

  8. New Integer Programming Formulations of the Generalized Travelling Salesman Problem

    Directory of Open Access Journals (Sweden)

    P. C. Pop

    2007-01-01

    Full Text Available The Generalized Travelling Salesman Problem, denoted by GTSP, is a variant of the classical travelling salesman problem (TSP, in which the nodes of an undirected graph are partitioned into node sets (clusters and the salesman has to visit exactly one node from every cluster. In this paper we described six distinct formulations of the GTSP as an integer programming. Apart from the standard formulations all the new formulations that we describe are 'compact' in the sense that the number of constraints and variables is a polynomial function of the number of nodes in the problem. In order to provide compact formulations for the GTSP we used two approaches using auxiliary flow variables beyond the natural binary edge and node variables and the second one by distinguishing between global and local variables. Comparisons of the polytopes corresponding to their linear relaxations are established.

    2011-01-01

    Most of computer science focuses on automatically solving given computational problems. I focus on automatically inventing or discovering problems in a way inspired by the playful behavior of animals and humans, to train a more and more general problem solver from scratch in an unsupervised fashion. At any given time, the novel algorithmic framework POWERPLAY searches the space of possible pairs of new tasks and modifications of the current problem solver, until it finds a more powerful problem solver that provably solves all previously learned tasks plus the new one, while the unmodified predecessor does not. The new task and its corresponding task-solving skill are those first found and validated. Newly invented tasks may require making previously learned skills more efficient. The greedy search of typical POWERPLAY variants orders candidate pairs of tasks and solver modifications by their conditional computational complexity, given the stored experience so far. This biases the search towards pairs that can...

    2010-12-01

    Statistical modeling is at the heart of many engineering problems. The importance of statistical modeling emanates not only from the desire to accurately characterize stochastic events, but also from the fact that distributions are the central models utilized to derive sample processing theories and methods. The generalized Cauchy distribution (GCD) family has a closed-form pdf expression across the whole family as well as algebraic tails, which makes it suitable for modeling many real-life impulsive processes. This paper develops a GCD theory-based approach that allows challenging problems to be formulated in a robust fashion. Notably, the proposed framework subsumes generalized Gaussian distribution (GGD) family-based developments, thereby guaranteeing performance improvements over traditional GCD-based problem formulation techniques. This robust framework can be adapted to a variety of applications in signal processing. As examples, we formulate four practical applications under this framework: (1) filtering for power line communications, (2) estimation in sensor networks with noisy channels, (3) reconstruction methods for compressed sensing, and (4) fuzzy clustering.

    Over 8000 foreign-born children, almost all from third-world countries, are adopted by citizens of the United States each year. Most primary care practitioners do not have enough experience to evaluate and manage their problems efficiently. We reviewed the medical care of the foreign-born adoptees followed up in a single pediatric group practice. The 128 children arrived from one of eight countries in Asia or Latin America at ages ranging from 1 month to 10 years; 57% were female. The median duration of follow-up was 20 months. The most common problems identified included deficient immunizations (37%), intestinal parasites (29%), emotional or behavioral problems (22%), skin diseases (16%), estimated age (12%), scabies and/or lice (10%), and congenital anomales (10%). Twenty-one other classes of problems were identified, including developmental delay, lactose intolerance, vision and hearing deficits, and chronic hepatitis B carrier status. At arrival or within one month, 49% of the children had acute infectious diseases, including upper respiratory tract infection, otitis media, rubeola, varicella, and mumps. Nineteen percent of the children underwent surgical procedures ranging from circumcision to cleft lip-palate repair; 46% of these children were never screened for hepatitis B. Fourteen percent were hospitalized at least once, 5% within the first month after arrival. We developed a simple protocol to screen foreign-born adopted children, allowing rapid identification of treatable problems at the least cost and inconvenience to the family. Thirty-six percent of the families made at least one preadoption visit, permitting an explanation of the protocol and potential problems before the child's arrival.

    TSAU Minhe; KAO Weiwen; CHANG Albert

    2009-01-01

    In recent years, more attention has been paid on artificial life researches. Artificial life(AL) is a research on regulating gene parameters of digital organisms under complicated problematic environments through natural selections and evolutions to achieve the final emergence of intelligence. Most recent studies focused on solving certain real problems by artificial life methods, yet without much address on the AL life basic mechanism. The real problems are often very complicated, and the proposed methods sometimes seem too simple to handle those problems. This study proposed a new approach in AL research, named "generalized artificial life structure(GALS)", in which the traditional "gene bits" in genetic algorithms is first replaced by "gene parameters", which could appear anywhere in GALS. A modeling procedure is taken to normalize the input data, and AL "tissue" is innovated to make AL more complex. GALS is anticipated to contribute significantly to the fitness of AL evolution. The formation of"tissue" begins with some different AL basic cells, and then tissue is produced by the casual selections of one or several of these cells. As a result, the gene parameters, represented by "tissues", could become highly diversified. This diversification should have obvious effects on improving gene fitness. This study took the innovative method of GALS in a stock forecasting problem under a carefully designed manipulating platform. And the researching results verify that the GALS is successful in improving the gene evolution fitness.

    2011-07-01

    We analyze the effect of electrode mislocation on the electroencephalography (EEG) inverse problem using the Cramér-Rao bound (CRB) for single dipolar source parameters. We adopt a realistic head shape model, and solve the forward problem using the Boundary Element Method; the use of the CRB allows us to obtain general results which do not depend on the algorithm used for solving the inverse problem. We consider two possible causes for the electrode mislocation, errors in the measurement of the electrode positions and an imperfect registration between the electrodes and the scalp surfaces. For 120 electrodes placed in the scalp according to the 10-20 standard, and errors on the electrode location with a standard deviation of 5mm, the lower bound on the standard deviation in the source depth estimation is approximately 1mm in the worst case. Therefore, we conclude that errors in the electrode location may be tolerated since their effect on the EEG inverse problem are negligible from a practical point of view.

    The generalized least squares (LS) problem appears in many application areas. Here W is an m × m symmetric positive definite matrix and A is an m × n matrix with m≥n. Since the problem has many solutions in rank deficient case, some special preconditioned techniques are adapted to obtain the minimum 2-norm solution. A block SOR method and the preconditioned conjugate gradient (PCG) method are proposed here. Convergence and optimal relaxation parameter for the block SOR method are studied. An error bound for the PCG method is given. The comparison of these methods is investigated. Some remarks on the implementation of the methods and the operation cost are given as well.

Substantial differences are moreover uncovered between what is meant by time in QM and in GR. These differences jointly source the Problem of Time: Nine interlinked facets which arise upon attempting concurrent treatment of the QM and GR paradigms, as is required in particular for a background independent theory of quantum gravity. A sizeable proportion of current quantum gravity programs - e.g. geometrodynamical and loop quantum gravity approaches to quantum GR, quantum cosmology, supergravity and M-theory - are background independent in this sense. This book's foundational topic is thus furthermore of practical relevance in the ongoing development of quantum gravity programs. This book shows moreover that eight of the nine facets of the Problem of Time already occur upon ...

    Australia will continue to face a general practitioner (GP) shortage unless a significant number of medical students make general practice their chosen career. Perceptions regarding general practice may influence career choices. Thus this study investigated what Australian medical students perceived to be the advantages and disadvantages of pursuing a career in general practice via an anonymous online survey. Fifty-one students indicated general practice to be their first ranked career preference, 200 indicated a career other than general practice, and 106 were undecided. Two-hundred and two students reported having been on a GP placement, whereas 88 students had not. Flexibility, continuity of patient care and work-life balance were the three most common stated advantages to pursuing a career in general practice whereas general practice being boring, poorly paid, and of low prestige were the three most common disadvantages stated. Some disadvantages stated by those with a non-GP preference were not stated by those with a GP preference (e.g. lack of procedural skills, lack of career advancement opportunities). Students with more than 80 h of GP placement experience were more likely to list the advantages of work-life balance and a diversity of problems/illnesses/patients than those with no placement experience but were also more likely to list the disadvantage of low prestige. Negative stereotypes regarding general practice continue to exist which may influence students' career choices.

    Full Text Available We propose two iterative algorithms for finding a common element of the set of solutions of finite generalized mixed equilibrium problems, the set of solutions of finite variational inclusions for maximal monotone and inverse strong monotone mappings, and the set of common fixed points of infinite nonexpansive mappings and an asymptotically κ-strict pseudocontractive mapping in the intermediate sense in a real Hilbert space. We prove some strong and weak convergence theorems for the proposed iterative algorithms under suitable conditions.

    Although medical liability (disciplinary, civil and criminal) is increasingly becoming an issue, few studies exist, particularly from the perspective of forensic science, which demonstrate the extent to which medical malpractice occurs, or when it does, the reasons for it. Our aims were to evaluate the current situation concerning medical liability in general surgery (GS) in Portugal, the reasons for claims, and the forensic evaluations and conclusions, as well as the association between these issues and the judicial outcomes. We analysed the Medico-Legal Council (CML) reports of the National Institute of Legal Medicine and Forensic Sciences of Portugal related to GS during 2001-2010. The judicial outcomes of each case were requested from the Public Prosecutor Office (PPO) and the court. Alleged cases of medical liability in GS represented 11.2% of the total cases analysed by the CML. We estimated that in Portugal, 4:100,000 surgeries are subject to litigation. The majority of complaints were due to the patient's death (75.4%), with laparoscopic cholecystectomy surgeries representing 55.2% of cases. In 76.1% of the cases, the CML believed that there was no violation of legesartis and in 55.2% of cases, no causal nexus was found between the medical practice and the alleged harm. The PPO prosecuted physicians in 6.4% of the cases and resulted in one conviction. Finally, the importance of the CML reports as a relevant technical-scientific tool for judicial decision was evident because these reports significantly (p < 0.05) influenced the prosecutor's decision, whether to prosecute or not.

  3. The agency problem and medical acting: an example of applying economic theory to medical ethics.

    2009-03-01

    In this article, the authors attempt to build a bridge between economic theory and medical ethics to offer a new perspective to tackle ethical challenges in the physician-patient encounter. They apply elements of new institutional economics to the ethically relevant dimensions of the physician-patient relationship in a descriptive heuristic sense. The principal-agent theory can be used to analytically grasp existing action problems in the physician-patient relationship and as a basis for shaping recommendations at the institutional level. Furthermore, the patients' increased self-determination and modern opportunities for the medical laity to inform themselves lead to a less asymmetrical distribution of information between physician and patient and therefore require new interaction models. Based on the analysis presented here, the authors recommend that, apart from the physician's necessary individual ethics, greater consideration should be given to approaches of institutional ethics and hence to incentive systems within medical ethics.

    Medical imaging technology is rapidly progressing. Positron emission tomography (PET) has played major role in the staging and choice of treatment modality in lung cancer patients. Magnetic resonance imaging (MRI) is now routinely used for mediastinal tumors and the use of diffusion-weighted images (DWI) may help in the diagnosis of malignancies including lung cancers. The benefits of medical imaging technology are not limited to diagnostics, and include simulation or navigation for complex lung resection and other procedures. Multidetector row computed tomography (MDCT) shortens imaging time to obtain detailed and precise volume data, which improves diagnosis of small-sized lung cancers. 3-dimensional reconstruction of the volume data allows the safe performance of thoracoscopic surgery. For lung lobectomy, identification of the branching structures, diameter, and length of the arteries is useful in selecting the procedure for blood vessel treatment. For lung segmentectomy, visualization of venous branches in the affected segments and intersegmental veins has facilitated the preoperative determination of the anatomical intersegmental plane. Therefore, the application of medical imaging technology is useful in general thoracic surgery.

    ENGLISH ABSTRACT: The Multi-Objective Generalized Assignment Problem (MGAP with two objectives, where one objective is linear and the other one is non-linear, has been considered, with the constraints that a job is assigned to only one worker – though he may be assigned more than one job, depending upon the time available to him. An algorithm is proposed to find the set of Pareto optimal solutions of the problem, determining assignments of jobs to workers with two objectives without setting priorities for them. The two objectives are to minimise the total cost of the assignment and to reduce the time taken to complete all the jobs.

Die twee doelwitte is om die totale koste van die opdrag te minimiseer en om die tyd te verminder om al die take te voltooi.

  6. Oblique derivative problem for general Chaplygin-Rassias equations

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The present paper deals with the oblique derivative problem for general second order equations of mixed (elliptic-hyperbolic) type with the nonsmooth parabolic degenerate line K1(y)uxx+|K2(x)|uyy+a(x,y)ux+b(x, y)uy+c(x,y)u=-d(x,y) in any plane domain D with the boundary D=Γ∪L1∪L2∪L3∪L4, whereΓ(■{y>0})∈Cμ2 (0<μ<1) is a curve with the end points z=-1,1. L1, L2, L3, L4 are four characteristics with the slopes -H2(x)/H1(y), H2(x)/H1(y),-H2(x)/H1(y), H2(x)/H1(y)(H1(y)=|k1(y)|1/2, H2(x)=|K2(x)|1/2 in {y<0}) passing through the points z=x+iy=-1,0,0,1 respectively. And the boundary condition possesses the form 1/2 u/v=1/H(x,y)Re[λuz]=r(z), z∈Γ∪L1∪L4, Im[λ(z)uz]|z=zl=bl, l=1,2, u(-1)=b0, u(1)=b3, in which z1, z2 are the intersection points of L1, L2, L3, L4 respectively. The above equations can be called the general Chaplygin-Rassias equations, which include the Chaplygin-Rassias equations K1(y)(M2(x)ux)x+M1(x)(K2(y)uy)y+r(x,y)u=f(x,y), in D as their special case. The above boundary value problem includes the Tricomi problem of the Chaplygin equation: K(y)uxx+uyy=0 with the boundary condition u(z)=φ(z) onΓ∪L1∪L4 as a special case. Firstly some estimates and the existence of solutions of the corresponding boundary value problems for the degenerate elliptic and hyperbolic equations of second order are discussed. Secondly, the solvability of the Tricomi problem, the oblique derivative problem and Frankl problem for the general Chaplygin- Rassias equations are proved. The used method in this paper is different from those in other papers, because the new notations W(z)=W(x+iy)=uz=[H1(y)ux-iH2(x)uy]/2 in the elliptic domain and W(z)=W(x+jy)=uz=[H1(y)ux-jH2(x)uy]/2 in the hyperbolic domain are introduced for the first time, such that the second order equations of

    Some studies on discharge against medical advice (AMA) in general hospitals report a prevalence between 0.7-7% with 11-42% of this population identified as psychiatric patients. To study the sociodemographic and psychopathological features of patients who leave AMA, we performed a retrospective case-control comparison study of length of hospitalization and presence of psychiatric disturbances on patients who left AMA from the University General Hospital in Catalan Spain over a two-year period. An analysis of the hospital epidemiological discharge register and retrospective chart review for presence of psychiatric disturbances found that AMA prevalence was 0.34%, the total discharge number in the 2-year period being 41,648. AMA rates by medical department were 0.44% for the internal medicine department; 0.24% for surgery; 0.26% for orthopedic surgery, 0.32% for obstetrics-gynecology and 0.93% for rehabilitation. The mean age for AMA patients was 38.63 years, with a higher number of men (59.9%). A total of 45.8% AMA discharges were from the internal medicine department. No significant differences were found in the average length of hospitalization between the AMA and control groups. The presence of psychiatric pathology was significantly higher among the AMA group (Phistory of psychiatric pathology, mainly narcotic dependence.

  8. Medical education and cognitive continuum theory: an alternative perspective on medical problem solving and clinical reasoning.

    Recently, human reasoning, problem solving, and decision making have been viewed as products of two separate systems: "System 1," the unconscious, intuitive, or nonanalytic system, and "System 2," the conscious, analytic, or reflective system. This view has penetrated the medical education literature, yet the idea of two independent dichotomous cognitive systems is not entirely without problems.This article outlines the difficulties of this "two-system view" and presents an alternative, developed by K.R. Hammond and colleagues, called cognitive continuum theory (CCT). CCT is featured by three key assumptions. First, human reasoning, problem solving, and decision making can be arranged on a cognitive continuum, with pure intuition at one end, pure analysis at the other, and a large middle ground called "quasirationality." Second, the nature and requirements of the cognitive task, as perceived by the person performing the task, determine to a large extent whether a task will be approached more intuitively or more analytically. Third, for optimal task performance, this approach needs to match the cognitive properties and requirements of the task. Finally, the author makes a case that CCT is better able than a two-system view to describe medical problem solving and clinical reasoning and that it provides clear clues for how to organize training in clinical reasoning.

    Objective To investigate the effect of problem - based learning( PBL)in a large class on reducing communication apprehension of medical students in general medical education. Methods A total of 120 5 - year clinical medical specialty students of Grade 2008 in China Medical University were enrolled as study objects. The students were divided into experimental group and control group by random number table and each group included 60 students. The experimental group adopted PBL teaching method in a large class,where students were helped to overcome communication apprehension by guiding and encouraging students to speak;the control group adopted traditional teaching methods. The two groups had the lessons of Introduction of General Practice taught by the same teachers for 24 credit hours. The communication apprehension of the students was evaluated by Personal Report of Communication Apprehension(PRCA-24)before and after class. Results Before teaching, the difference of PRCA-24 scale total point and Item - subscale point between the experimental group and the control group was not significant(P > 0. 05). After teaching,PRCA-24 scale total point of the experimental group was lower than the control group and the difference was significant( P 0. 05). Conclusion PBL in a large class can reduce total points,team points and public points of PRCA-24 scale in general medical teaching and is in favour of relieving the communication apprehension of medical students.%目的:探讨在全科医学教学中开展大班以问题为基础的学习(PBL)对改善医学生交流恐惧的作用。方法以中国医科大学2008级五年制临床医学专业的120名四年级学生为研究对象,采用随机数字表法分为试验组和对照组各60人。试验组采用大班 PBL 教学方法,采用引导、鼓励发言的办法帮助学生克服交流恐惧;对照组采用传统教学方法,两组均由相同教师教授《全科医学概论》24个学时。教学前后

    1977-11-01

    The patient with persistent foul drainage from a previously operated-on mastoid cavity has a serious problem that requires aggressive attention from the otologic surgeon. The ear must be carefully evaluated in the office. Careful cleaning of the cavity and effective application of medication will dry up many of these cavities. Revision surgery of the ear requires a systematic approach using all the techniques of modern otologic surgery. This means the use of a post-auricular incision and wide bone removal combined with bone removal combined with obliteration techniques and grafting of the middle ear. This approach was used in 29 ears in 27 patients. Rapid healing and a trouble-free, dry ear was obtained in 26 patients or 90% of the operated-on cases.

    Twenty-seven general medical practitioners (GPs) were administered WHO semi-structured schedule enquiring "The Management of Alcohol-Related Problems in General Practice". Majority of the GPs had some involvement in each one of the specified alcohol-related problems. The involvement in alcohol and health education had been modest. Involvement in the control and regulatory activities was minimal. None of them felt that they had any role in the development of health and alcohol policy. Treatment response lo three typical situations appeared to be quite appropriate. To regulate production, to market less potent drinks at cheaper rates, to organize public health education programme through mass media were the suggestions made by them. It is suggested that GPs can and should be encouraged in leadership roles in policy decisions regarding the delivery of services, control and regulation of alcohol and research.

  12. POWERPLAY: Training an Increasingly General Problem Solver by Continually Searching for the Simplest Still Unsolvable Problem

    2013-06-01

    Full Text Available Most of computer science focuses on automatically solving given computational problems. I focus on automatically inventing or discovering problems in a way inspired by the playful behavior of animals and humans, to train a more and more general problem solver from scratch in an unsupervised fashion. Consider the infinite set of all computable descriptions of tasks with possibly computable solutions. The novel algorithmic framework POWERPLAY (2011 continually searches the space of possible pairs of new tasks and modifications of the current problem solver, until it finds a more powerful problem solver that provably solves all previously learned tasks plus the new one, while the unmodified predecessor does not. Wow-effects are achieved by continually making previously learned skills more efficient such that they require less time and space. New skills may (partially re-use previously learned skills. POWERPLAY's search orders candidate pairs of tasks and solver modifications by their conditional computational (time & space complexity, given the stored experience so far. The new task and its corresponding task-solving skill are those first found and validated. The computational costs of validating new tasks need not grow with task repertoire size. POWERPLAY's ongoing search for novelty keeps breaking the generalization abilities of its present solver. This is related to Goedel's sequence of increasingly powerful formal theories based on adding formerly unprovable statements to the axioms without affecting previously provable theorems. The continually increasing repertoire of problem solving procedures can be exploited by a parallel search for solutions to additional externally posed tasks. POWERPLAY may be viewed as a greedy but practical implementation of basic principles of creativity. A first experimental analysis can be found in separate papers [58, 56, 57].

    Junior doctors have reported shortcomings in their general competencies, such as organisational skills and teamwork. We explored graduates' perceptions of how well their training had prepared them for medical practice and in general competencies in particular. We compared the opinions of graduates from problem-based learning (PBL) and non-PBL schools, because PBL is supposed to enhance general competencies. We analysed the responses of 1159 graduates from 1 PBL and 4 non-PBL schools to a questionnaire survey administered 18 months after graduation. Compared with their non-PBL colleagues, the PBL graduates gave higher ratings for the connection between school and work, their medical training and preparation for practice. According to the graduates, the most frequently used competencies with sufficient coverage during medical training were expert knowledge, profession-specific skills and communication skills. The majority of the PBL graduates, but less than half of the non-PBL graduates, indicated that communication skills had been covered sufficiently. All the graduates called for more curriculum attention on working with computers, planning and organisation, and leadership skills. More PBL graduates than non-PBL graduates indicated that they had learned profession-specific methods, communication skills and teamwork in medical school. Overall, the graduates appeared to be satisfied with their knowledge and skills. The results suggest that the PBL school provided better preparation with respect to several of the competencies. However, both PBL and non-PBL graduates identified deficits in their general competencies, such as working with computers and planning and organising work. These competencies should feature more prominently in undergraduate medical education.

    China, a country with about one fifth of the world' s population, has been gaining a rapideconomic growth since 1980s. This country has around 5 million blind people, accountingfor 18% of the blind in the world. The major causes of blindness include cataract,corneal diseases, trachoma, glaucoma, vitreoretinopathy and a number of factorscontributing to blindness in children. The principal cause of blindness in China was nolonger trachoma but cataracts. Vitamin A deficiency remains a public health problem inthe under-developed areas.Age-related conditions in China, such as vision loss due tocataract and retinal disorders, will increase accordingly if no preventive meaunes aretaken. Glaucoma and diabetic retinopathy appear to be predominant induction of thedevastating blind. In this fast developing country blindness is not only a medical orhealth, but also a social problem. Developed strategies have been adopted simultaneouslyby national efforts under the leadership of the government, international agencies,nongovernmental organizations, as well as private sectors in their every-day work toprevent and treat blindness.

    2013-01-01

    In a living organism 72% of energy exchange occur in the visceral organs, which comprise only 5-6% of the total body mass. The remaining energy is spent at the expense of the skin, bones, connective tissues, resting muscles. The level ofenergy expenditure determines the general physiological state of a human organism, serves for the diagnostics of various diseases, in particular, the diseases of endocrine system, the disruptions of thermoregulation, protein, carbohydrate, and lipometabolism, etc. It should be mentioned that in modern textbooks of physiology, pathophysiology, and biology the problem of energy exchange in humans and animals is given inadequate consideration. Traditionally it occupies only 2-2.5% of the content. Meanwhile, new problems of energy exchange have appeared recently, which almost never were advanced earlier. These are,for example, the reasons and mechanisms of high energy expenditure under conditions of metabolism, the significance of the coefficient of efficiency of a human organism in physiology, special processes previously unknown of the organism heat exchange with the environment, physiological and social components of human energy exchange. There is also a problem of a theoretical possibility of life without energy.

    1988-07-01

    Over a 6-year period at the University Hospital in London, Ont., 101 patients underwent heart transplantation and 5 heart-lung transplantation. The authors review the general surgical problems identified from the charts of 13 of these patients. In the early postoperative period (within 30 days), laparotomy was required for pancreatitis (one), perforated peptic ulcer (two), cholecystectomy (one), pancreatic cyst (one) and appendicitis (one). In addition, a spontaneous colocutaneous fistula and spontaneous pneumoperitoneum occurred; both were managed conservatively. Later, three patients required cholecystectomy; one underwent a below-knee and a Symes amputation for dry gangrene and one surgical correction of a lymphocele. The incidence of surgical problems (13%) indicates an increased susceptibility in this group of patients. Four of the 13 patients died. Pancreatitis is a well-recognized complication of cardiac surgery; it is frequently associated with a normal or only slightly elevated serum amylase level, making a definitive diagnosis without laparotomy almost impossible. Persistence of abdominal signs should signal the need for exploratory surgery. During the early postoperative period and in the absence of multiorgan failure, immediate operation for an acute abdomen is usually successful. Despite the additional risk, cardiac transplantation does not preclude later surgery, but immunosuppression must be continued and carefully monitored.

    1996-12-31

    This paper presents an efficient iterative scheme for the generalized Stokes problem, which arises frequently in the simulation of time-dependent Navier-Stokes equations for incompressible fluid flow. The general form of the linear system is where A = {alpha}M + vT is an n x n symmetric positive definite matrix, in which M is the mass matrix, T is the discrete Laplace operator, {alpha} and {nu} are positive constants proportional to the inverses of the time-step {Delta}t and the Reynolds number Re respectively, and B is the discrete gradient operator of size n x k (k < n). Even though the matrix A is symmetric and positive definite, the system is indefinite due to the incompressibility constraint (B{sup T}u = 0). This causes difficulties both for iterative methods and commonly used preconditioners. Moreover, depending on the ratio {alpha}/{nu}, A behaves like the mass matrix M at one extreme and the Laplace operator T at the other, thus complicating the issue of preconditioning.

    Full Text Available Background and purpose: A 3-unit course is dedicated to general language in medical universities and the vocabulary and text structure of the courses have usually no relation to medical language. We examine whether teaching general language will be as effective as medical language as assessed through recall of general and medical vocabulary and text structure knowledge. Methods: an experimental study was designed, in that, the third year students who had participated in the 3-unit general language classes in the first year of their General Practitioner (GP program were selected and sat for a 60 MCQ tests. The 60 MCQ tests consisted of 30 questions of general language, 25 vocabulary and 5 comprehension questions and also 30 questions of medical language, 25 technical and semi-technical vocabulary and 5 comprehension questions. In all, 145 medical students attended the exam which took 40 minutes to accomplish. Results: The results of the study indicated that memory retention was significantly lower in general language than medical language. The technical and semi-technical vocabulary items were significantly better recalled and the medical text was significantly better understood by the participants. Conclusion: A 3-unit course in general language may be a futile effort since the students will not be exposed to the same vocabulary and text structure knowledge in later years of their GP program. It is recommended that the focus of all the university English courses be on the medical language. Key words: Medical Vocabulary, English For Specific Purposes, ESP

  1. An Algorithm to Extract Rules from Artificial Neural Networks for Medical Diagnosis Problems

    CERN Document Server

    Kamruzzaman, S M

    2010-01-01

    Artificial neural networks (ANNs) have been successfully applied to solve a variety of classification and function approximation problems. Although ANNs can generally predict better than decision trees for pattern classification problems, ANNs are often regarded as black boxes since their predictions cannot be explained clearly like those of decision trees. This paper presents a new algorithm, called rule extraction from ANNs (REANN), to extract rules from trained ANNs for medical diagnosis problems. A standard three-layer feedforward ANN with four-phase training is the basis of the proposed algorithm. In the first phase, the number of hidden nodes in ANNs is determined automatically by a constructive algorithm. In the second phase, irrelevant connections and input nodes are removed from trained ANNs without sacrificing the predictive accuracy of ANNs. The continuous activation values of the hidden nodes are discretized by using an efficient heuristic clustering algorithm in the third phase. Finally, rules ar...

    2010-06-01

    In Korea, students should have the consciousness of 'I' and 'we' to adapt well in society. Medical students in Korea must develop interpersonal and intrapersonal characteristics that are in accordance with Korean culture. This study intends to determine the relationship between the level of I-consciousness/we-consciousness and interpersonal problems in medical students. The I-consciousness/we-consciousness Inventory and the Inventory of Interpersonal Problems were used for 212 first year medical students and 191 second year medical students at Yonsei University College of Medicine in 2008. The levels of I-consciousness/we-consciousness and interpersonal problems in medical students were higher than those of other general college students. There was a significant inverse correlation between the level of I-consciousness/we-consciousness and interpersonal problems for 118 of 130 factors. The higher the level of I-consciousness/we-consciousness in medical students is, the fewer interpersonal problems there are. Educational programs that take into account the consciousness of 'I' and 'we' are useful for the development of medical students' personalities.

    Chest pain was identified as a specific medical problem space, and disease classes were modeled to define it. Results from a test taken by 628 medical residents indicate a second-order factor structure that suggests that chest pain is a multidimensional problem space. Implications for medical education are discussed. (SLD)

    Patients with complex medical problems should be counselled about the need for highly effective contraception. As failure resulting in pregnancy, could cause significant morbidity and mortality. The LNG-IUS has gained great popularity and generally has a low side effect profile; however, perforation of the uterus and migration of the device is a potentially serious complication known to be associated with its use. The current accepted management is removal of the device from the abdominal cavity in order to prevent further morbidity. However this is not always a simple matter in patients who have complex medical problems and who are deemed unfit for surgery. Each time the patient comes for renewal of the contraceptive method, clinicians need to reassess the risks and benefits. This is particularly relevant in patients who have complex medical problems where special attention needs to be given, not only to immediate risks but also to long-term ones. Careful individualised counselling and consideration are paramount and perhaps it would have been prudent to discuss vasectomy with this patient and her husband (as the first line of contraception), as this may have avoided the ensuing complications arising from the chosen method.

    All statins inhibit hydroxymethylglutaryl Coenzyme A Reductase but each has a different chemical structure that may have individual advantages. Some pharmaceutical companies have minimized side effects and stated that dose has no relation to incidence. To the contrary, dose is related to side effects with all statins. Myopathy occurs in up to 10.5% of patients taking a high dose. There is an attempt to sell statins that have lost patent protection over-the-counter. However, evidence supports medical supervision as offering greatest patient safety. Concerns were raised about ezetimibe after the initial ENHANCE (efficacy) and SEAS (cancer risk) study but these concerns appear to have been answered. Fenofibrate can be used with a statin but gemfibrozil is contraindicated. Coenzyme Q-10 possibly helps to mitigate the risk of myopathy with a statin but evidence is not universally accepted. JUPITER represented a valid outcomes study but made a claim that rosuvastatin has special value in risk management because of decreased high sensitivity C-Reactive Protein. This actually occurs with any statin, a decrease also enhanced by ezetimibe. Statins have benefited the lives of our patients but, as with any treatment, the physician needs to look critically at all the problems and claims made.

    This pilot study aimed to explore the perceptions of general medical practitioners (GPs) towards the professional training and roles of community pharmacists. A self-administered questionnaire was distributed to all private clinics (n=160) run by GPs in a northern state of Malaysia. The instrument contained questions to evaluate the practitioners' level of agreement using a 5-point Likert-type scale. Of 160 GPs, 80 returned the questionnaire (response rate 50%). The respondents agreed that: GPs should consider the community pharmacists' recommendations whenever there is/are any problem(s) with the prescriptions given by them (46.3%); community pharmacists are the best healthcare professionals to educate patients about safe and appropriate use of medications (52.5%); the pharmacy profession had undergone a major metamorphosis from a product-oriented profession to a more patient-centred and outcome-oriented one (61.3%); if dispensing separation is implemented, they will work closely with the community pharmacists in monitoring patients' pharmacotherapeutic outcomes (77.5%). The current findings suggest that GPs would support an extension of the role of the community pharmacists in number of activities of patient care activities such as medication counselling. Thus, suggesting potential collaborative care between GPs and community pharmacists towards patient care and the needs to develop and incorporate topics on inter-professional relationship in the current medical and pharmaceutical education curriculums.

  9. Cognitive problem solving patterns of medical students correlate with success in diagnostic case solutions.

    Directory of Open Access Journals (Sweden)

    Jan Kiesewetter

    Full Text Available CONTEXT: Problem-solving in terms of clinical reasoning is regarded as a key competence of medical doctors. Little is known about the general cognitive actions underlying the strategies of problem-solving among medical students. In this study, a theory-based model was used and adapted in order to investigate the cognitive actions in which medical students are engaged when dealing with a case and how patterns of these actions are related to the correct solution. METHODS: Twenty-three medical students worked on three cases on clinical nephrology using the think-aloud method. The transcribed recordings were coded using a theory-based model consisting of eight different cognitive actions. The coded data was analysed using time sequences in a graphical representation software. Furthermore the relationship between the coded data and accuracy of diagnosis was investigated with inferential statistical methods. RESULTS: The observation of all main actions in a case elaboration, including evaluation, representation and integration, was considered a complete model and was found in the majority of cases (56%. This pattern significantly related to the accuracy of the case solution (φ = 0.55; p<.001. Extent of prior knowledge was neither related to the complete model nor to the correct solution. CONCLUSIONS: The proposed model is suitable to empirically verify the cognitive actions of problem-solving of medical students. The cognitive actions evaluation, representation and integration are crucial for the complete model and therefore for the accuracy of the solution. The educational implication which may be drawn from this study is to foster students reasoning by focusing on higher level reasoning.

    Full Text Available In this article, we study the bifurcation of limit cycles from the harmonic oscillator $\\dot{x}=y$, $\\dot{y}=-x$ in the system $$ \\dot{x}=y,\\quad \\dot{y}=-x+\\varepsilon f(y\\big(1-x^2\\big, $$ where $\\varepsilon$ is a small positive parameter tending to 0 and f is an odd polynomial of degree 2n + 1, with n an arbitrary but fixed natural number. We prove that, the above differential system, in the global plane, for particularly chosen odd polynomials f of degree 2n + 1 has exactly n + 1 limit cycles and that this number is an upper bound for the number of limit cycles for every case of an arbitrary odd polynomial f of degree 2n + 1. More specifically, the existence of the limit cycles, which is the first of the main results in this work, is obtained by using the Poincare's method, and the upper bound for the number of limit cycles can be derived from the work of Iliev [4]. We also investigate the possible relative positions of the limit cycles for this differential system, which is the second main problem studying in this work. In particular, we construct differential systems with n given limit cycles and one limit cycle whose position depends on the position of the previous n limit cycles. Finally, we give some examples in order to illustrate the general theory presented in this work.

    In this paper, we try to determine the near-optimum solution for the capacitated arc routing problem (CARP). In general, NP-hard CARP is a special graph theory specifically arises from street services such as residential waste collection and road maintenance. By purpose, the design of the CARP model and its solution techniques is to find optimum (or near-optimum) routing cost for a fleet of vehicles involved in operation. In other words, finding minimum-cost routing is compulsory in order to reduce overall operation cost that related with vehicles. In this article, we provide a combination of various heuristics algorithm to solve a real case of CARP in waste collection and benchmark instances. These heuristics work as a central engine in finding initial solutions or near-optimum in search space without violating the pre-setting constraints. The results clearly show that these heuristics algorithms could provide good initial solutions in both real-life and benchmark instances.

  12. A critical theory of medical discourse: how patients and health professionals deal with social problems.

    Waitzkin, H; Britt, T

    1989-01-01

    Criticism of social context does not generally appear in medical encounters. When contextual issues arise in medical discourse, messages of ideology and social control may become apparent, usually without the conscious awareness of the participants. By easing the physical or psychological impact of contextual difficulties, or by encouraging patients' conformity to mainstream expectations of desirable behavior, encounters with doctors can help win patients' consent to troubling social conditions. Seen in this light, doctor-patient encounters become micropolitical situations that do not typically encourage explicit statements or actions by health professionals to change contextual sources of their patients' difficulties. A critical theory influenced by structuralism suggests that the surface meanings of signs in medical discourse prove less important than their structural relationships. In addition, a theoretical approach adopting elements of post-structuralism and Marxist literary criticism emphasizes the marginal, absent, or excluded elements of medical discourse. Contextual features that shape a text include social class, sex, age, and race. Through the underlying structure of medical discourse, contextual problems are expressed, marginalized, and managed.

Furthermore, we prove under some mild conditions that the proposed iterative algorithm converges strongly to a common element of the above four sets, which is a solution of the optimization problem related to a strongly positive bounded linear operator. The results presented in the paper improve and extend the recent ones announced by many others.

    The aims of the study were to examine the detection rate of common mental disorders (CMD) by general medical doctors and which patient-related factors associated with increased chances of detection in Taiwan. A two-phase case-identification using the Chinese Health Questionnaire and the Revised Clinical Interview Schedule (CIS-R) was carried out among a sample of consecutive new attenders (n=990) in community and hospital-based clinics. Physicians completed a checklist of the problems that they identified during each consultation. General medical doctors missed more than 85% of the CIS-R cases of defined mental disorder. Physicians performed better identification of CMD among attenders with a higher socioeconomic status, without physical illness, having psychological presentation or attribution, suffering from more serious common mental disorders, or having a longer duration of illness. The very low identification rate of CMD has strongly implied the need to improve postgraduate training in psychiatry for general medical doctors in Taiwan. Simply adding one or two questions about mood and attributions of presenting symptoms might help physicians to identify CMD.

    A partnered medication review and charting model involving a pharmacist and medical officer was implemented in the Emergency Short Stay Unit and General Medicine Unit of a major tertiary hospital. The aim of the study was to describe the safety and effectiveness of partnered medication charting in this setting. A partnered medication review and charting model was developed. Credentialed pharmacists charted pre-admission medications and venous thromboembolism prophylaxis in collaboration with the admitting medical officer. The pharmacist subsequently had a clinical discussion with the treating nurse regarding the medication management plan for the patient. A prospective audit was undertaken of all patients from the initiation of the service. A total of 549 patients had medications charted by a pharmacist from the 14th of November 2012 to the 30th of April 2013. A total of 4765 medications were charted by pharmacists with 7 identified errors, corresponding to an error rate of 1.47 per 1000 medications charted. Partnered medication review and charting by a pharmacist in the Emergency Short Stay and General Medicine unit is achievable, safe and effective. Benefits from the model extend beyond the pharmacist charting the medications, with clinical value added to the admission process through early collaboration with the medical officer. Further research is required to provide evidence to further support this collaborative model. Copyright © 2015. Published by Elsevier Ltd.

Learners’ cooperation in the teaching process in order to increase teaching effectiveness and promotion is considered significant. The aim of the present study was to determine the effect of establishment of student working group on the teaching general embryology course to medical students.Methods: Ten students (1% of medical embryology course were selected to analyze the topics to be taught before each session according to lesson plan, and observe the whole teaching process during lesson presentation. Then, having asked the other students’ viewpoints and discussing with one another, they provided the teacher with a written report on the strengths and weaknesses of the teaching and its problems. The teacher analyzed the problems proposed by the working group to improve teaching process in the next session. At the end of the semester, a questionnaire was administered to all the participants. Data were analyzed using descriptive statistics.Results: The mean of students’ scores was 74.26%. The most important findings obtained in this study included positive role of film projection in teaching the materials (95.34%, significance of presentation of various pictures from different books (88.4%, changing students’ attitude toward application of embryology in different diseases (86%, and repetition of previous session’s pictures (83.75%. The weak points mentioned, however, were physical problems of the classroom and deficiency of audio visual equipment.Conclusion: Student working group has a positive impact on the teaching medical general embryology.

    2008-11-01

    The claim of an individual to assure his health and life, to assume and compensate the damage from diseases and accidents, had already appeared in the system of the ancient Roman law in the form of many singular legal institutions. In lack of a unified archetype of regulation, we have to analyse the damages caused in the health or corporal integrity of different personal groups: we have to mention the legal interpretation of the diseases or injuries suffered by serves, people under manus or patria potestas and free Roman citizens. The fragments from the Digest od Justinian do not only demonstrate concrete legal problems, but they can serve as a starting point for further theoretical analyses. For example: if death is the consequence of a medical failure, does the doctor have any kind of liability? Was after-care part of the healing process according to the Roman law? Examining these questions, we should not forget to talk about the complex liability system of the Roman law, the compensation of the damages caused in a contractual or delictual context and about the lex Aquilia. Although these conclusions have no direct relation with the present legal regulation of risk assumption, we have to see that analysing the examples of the Roman law can be useful for developing our view of a certain theoretical problem, like that of the modern liability concept in medicine as well.

    In this paper we investigate the problem of locating medications in automated dispensing cabinets (ADCs) to minimize human selection errors. We formulate the multiple-drawer medication layout problem and show that the problem can be formulated as a quadratic assignment problem. As a way to evaluate various medication layouts, we develop a similarity rating for medication pairs. To solve industry-sized problem instances, we develop a heuristic approach. We use hospital ADC transaction data to conduct a computational experiment to test the performance of our developed heuristics, to demonstrate how our approach can aid in ADC design trade-offs, and to illustrate the potential improvements that can be made when applying an analytical process to the multiple-drawer medication layout problem. Finally, we present conclusions and future research directions.

    He, Yunfeng; Du, Xiangyun; Toft, Egon

    2017-01-01

    In daily patient-history taking and diagnosis practice, doctors ask questions to gather information from patients and narrow down diagnostic hypotheses. Training medical students to be efficient problem solvers through the use of questioning is therefore important. In this study, the effectiveness...... of problem-based learning (PBL) and lecture-based learning in improving the questioning abilities of medical students (N = 104) was assessed by a modified 20-question task. In this task, the participants were asked to identify target pictures by asking questions, the problem-solving process of which...... resembles that of the diagnosis scenario. Moreover, this task requires no medical knowledge, and therefore allows knowledge- irrelevant questioning abilities to be assessed independently. The results show that PBL students generally ask more efficient questions and use fewer questions to complete the task...

    Counterfeit medicines pose an ever-increasing threat to public health, although precise tracking of illegal counterfeit prescription drug activity is difficult. Available data indicate that all types of medications have been targeted. Adverse health effects, including death, have resulted from using counterfeit medications; consumers who self-medicate without appropriate interactions with the healthcare system rarely receive adequate healthcare. The Internet provides a large, convenient route for counterfeiters to reach potential buyers with unregulated, often dangerous, products. The majority of medicines purchased via unverified Internet sites are counterfeit; often, these products lack the purported drug compound or have variable concentrations of active ingredients and sometimes contain dangerous toxins. Although many consumers acknowledge some degree of risk with purchasing medications via the Internet, speed, convenience and cost often prompt these purchases. Counterfeit medications also have been detected in the legitimate supply chain, but represent a significantly smaller proportion of sales than those purchased via the Internet. Pilot programmes in Europe have demonstrated that product verification systems prevent penetration of counterfeit products into the legitimate supply chain. Significant EU legislation, including stronger penalties for counterfeiting, is in development. In the United Kingdom, the Medicines and Healthcare Products Regulatory Agency (MHRA) launched an initiative against counterfeit medication. Healthcare professionals should report suspected cases of counterfeit medication to the MHRA, be alert to threats to the medicine supply, and provide practical advice to patients about ordering medications online, including avoiding unregulated Internet pharmacies, and being suspicious of sites offering substantial discounts and prescription-only medication without a prescription. © 2011 Blackwell Publishing Ltd.

  20. The limits of empathy: problems in medical education and practice.

    Science.gov (United States)

    Smajdor, Anna; Stöckl, Andrea; Salter, Charlotte

    2011-06-01

    Empathy is commonly regarded as an essential attribute for doctors and there is a conviction that empathy must be taught to medical students. Yet it is not clear exactly what empathy is, from a philosophical or sociological point of view, or whether it can be taught. The meaning, role and relevance of empathy in medical education have tended to be unquestioningly assumed; there is a need to examine and contextualise these assumptions. This paper opens up that debate, arguing that 'empathy', as it is commonly understood, is neither necessary nor sufficient to guarantee good medical or ethical practice.

    Full Text Available PURPOSES: to identify the prevalence of the use of psychiatric drugs among patients admitted to medical and surgical clinics of a general hospital, and also the factors related to the consumption of this type of medication. METHOD: this is a transversal, descriptive, correlational study with quantitative analysis. For the collection of data, there was use of structured interviews and also reference to medical files. RESULTS: there was confirmation of a high prevalence of users of psychiatric drugs, which was associated to the female sex, to people who do not practice Roman Catholicism, and admittance to the clinic not covered by the Single Health System (Sistema Único de Saúde - SUS, as well as the presence of common mental disorders. Benzodiazepine drugs were the most commonly used psychiatric drugs. Among the total number of users, there has been the identification of patients who were not aware that they were receiving such medication. Doctors who are not psychiatrists were responsible for most prescriptions of psychiatric drugs. CONCLUSIONS: this signals the need to prepare health professionals to deal with psychological and social problems commonly found in clinical practice, in order to promote the rational use of psychiatric drugs.

    Full Text Available Professional ethics education is one of components of an educational system and a part of philosophy that helps us to choice a correct life style. More than tradition and devotion and based on logical foundations ethics interpetes us what permitted us to do and we shouldn’t do and helps us to relate critically and impartially and regularly enchance our set of values. Therefore among GPs traits ethical problems occupy an important place. In developed countries is paid a particular attention to the problem how to from it in GPs but there are many problems to be solved.

    Full Text Available The general medical services (GMS scheme provides care free at the point of use for the 30% most economically deprived section of the population and the elderly. Almost all people of over-70-year olds are eligible for the GMS scheme potentially directing resources away from those most in need. The aim of this study is to analyse the relationship between practice GMS income and deprivation amongst Dublin-based general practitioners (GPs. The practice GMS income in Dublin was analysed in relation to practice characteristics including the number of GPs, catchment area population, proportion of over-70-year olds in the catchment area, catchment deprivation, number of GMS GPs within 2 km, and average GMS practice income within 2 km. Practice GMS income was highest in deprived areas but is also a valuable source of income in the least deprived areas. The capitation rate for over-70-year olds provides an incentive for GPs to locate in affluent areas and potentially directs resources away from those in greater need.

    Full Text Available Background: Incidence of stress among medical students has been reported to be between high and very high. Medical students in pre-clinical phase are more likely to develop psychological distress than medical students in clinical phase. It may affect academic performance and lead to anxiety, depression and substance abuse. Methods: First year students of one government medical college and one private medical college of Kanpur, Uttar Pradesh, India, were surveyed to find out stress and mental health problems shortly after their admission. Results: The two colleges showed difference in the frequencies of a number of factors- current stress, sleep problem, sad mood, both parents working, parents giving sufficient time, non-participation in extra-curricular activities, sharing problem with their families, having break-up in a romantic relationship and poor relationships with classmates and roommate. More students of the government medical college reported to have current stress compared to the students of the private medical college. While all students of the government medical who had stress since admission did not recover from it, 55.56% of students of the private medical college recovered from it at the time of our survey. Conclusion: a Psychiatry Department of every medical college should be involved in screening 1st year students having stress and mental health problems and managing them. b Medical education should be imparted in more relaxed and fun filled manner to help students cope with the long and difficult course.

    Medical tourism is the movement of patients through a global network of health services. Medical tourists seek affordable healthcare on a timely basis in a variety of destination nations. The expansion of global medical services has sparked immense economic growth in developing nations and has created a new market for advertising access to care. Beyond offering a unique untapped market of services, medical tourism has invited a host of liability, malpractice and ethical concerns. The explosion of off-shore "mini-surgical" vacations will surely incite global unification and increased access, quality and affordability of care. Medical tourism is a dynamic subset of global health care that incorporates a variety of services, procedures and venues of care. Health insurance coverage, the impact on domestic and global markets, and the use of international standards of care will be examined in combination with quality, access and cost parameters. The global nature of medical tourism invites a variety of legal and ethical issues and calls for an organizational body to monitor this new phenomenon. Finally, the future implications of the globalization of health services and systems will be discussed.

    According to the European Federation of Organizations for Medical Physics (EFOMP) policy statement No. 13, "The rapid advance in the use of highly sophisticated equipment and procedures in the medical field increasingly depends on information and communication technology. In spite of the fact that the safety and quality of such technology is vigorously tested before it is placed on the market, it often turns out that the safety and quality is not sufficient when used under hospital working conditions. To improve safety and quality for patient and users, additional safeguards and related monitoring, as well as measures to enhance quality, are required. Furthermore a large number of accidents and incidents happen every year in hospitals and as a consequence a number of patients die or are injured. Medical Physicists are well positioned to contribute towards preventing these kinds of events". The newest developments related to this increasingly important medical speciality were presented during the 8th European Conference of Medical Physics 2014 which was held in Athens, 11-13 September 2014 and hosted by the Hellenic Association of Medical Physicists (HAMP) in collaboration with the EFOMP and are summarized in this issue.

    2014-07-01

    To describe and report outcomes of interventions implemented in the preclerkship curriculum at the David Geffen School of Medicine at UCLA to guide students toward use of high-quality information sources and build a foundation for developing fluency in applying primary medical literature to answer clinical questions. The authors introduced three phases of change to instruction in literature searching and sourcing for beginning medical students writing learning issue essays: in phase 1 (2003-2006), students were introduced to online resources during orientation week and received a lecture on high-yield literature searching midway through their first curricular block; in phase 2 (2007-2008), the high-yield lecture shifted to orientation week, and a resource matrix and librarian-guided workshop on locating authoritative sources were added; and in phase 3 (2009), peer evaluation and collaboration were implemented. To track changes in sourcing skills, the authors analyzed 3,199 references from 665 essays written by 465 first-year students for two problem-based learning (PBL) cases during the first block of one representative year per phase (2006, 2008, 2009). Over the study period, the authors found significantly increased citations to peer-reviewed journal articles and guidelines and decreased citations to general public Web sites and highly abstracted resources. Peer feedback and collaboration in phase 3 were associated with maintenance of these gains. Early introduction of instruction on medical literature searching and sourcing, a librarian-guided workshop, and peer collaboration and feedback improved the quality of references cited by students in PBL essays during their first curricular block.

    Full Text Available As India marches towards an exciting new future of growth and progress, medical education will play pivotal role in crafting a sustained development agenda. The idea of creating a healthy society is no longer a debatable luxury; its significance has been grasped by policy shapers worldwide. In a developing nation like India, medical services play a very important role in the well-being of their citizens and indirectly play a very important part in the economic and overall development of the nation. The medical education system is suffering from misdistribution, traditional curriculum, poor assessment, neglected research and lack of faculty development programmes. ‘Vision 2015’ has potential for creating substantial change in Indian medical education. A stronger strategic approach will ensure a solid foundation for the improvement in the health status of India. Conventional-theoretical and experimental teaching blended with a system of teaching which is innovative, aiming to develop under-graduates and post-graduates as community-teachers, true-academician/researcher should be emphasized. This paper focuses on the various challenges of medical education in India.

    With the appearance of the "biological-psychological-social" medical model, the purpose, value and significance of medicine are reviewed and reconsidered by the people, and the history of medicine becomes one of the core subjects in the medical humanist education, along with change of the teaching of general western medical history. Medical history is no longer the accumulation of the achievements of human knowledge and medical experience, the intellectual history of theorytransformation, and the history of reformation of medical technologies, but a concrete and colorful living situation, displayed by the scientists, physicians and normal peoplecommunity during the process of their consistent recognition and transformation on medicine. Therefore, the teaching of generalwestern medical history should adjust the compilation of teaching materials, update the educational concept, change the contents, methods of teaching and examination in order to lay stress on the cultural viewpoint and the function of humanity and quality of education.

  19. Risk of medication errors at hospital discharge and barriers to problem resolution.

    Science.gov (United States)

    Enguidanos, Susan M; Brumley, Richard D

    2005-01-01

    Medication errors are common among older adults, particularly among those who are at heightened risk due to transfer between care settings. Determining accurate medications for hospitalized patients is a complicated process. This paper presents findings from a small pilot study conducted to identify medication documentation problems at the point of hospital discharge among older adults and the problems encountered in developing new technological systems to address these problems. A prospective study was conducted within a managed care medical center that included patient and physician surveys and chart reviews. A review of 104 medical records revealed several problems in the documentation of patient medication including legibility, use of medical abbreviations and incomplete and missing entries. While patients overall were satisfied with medications communication efforts at discharge, physicians surveyed reported that these methods were inadequate in transmitting medication lists to primary care physicians, patients and other care providers. Patients reported taking more drugs than what were listed in the medical record. These findings led to the development, testing, and implementation of an electronic medication sheet. Despite the success in developing this new system, few physicians engaged in its use, with most preferring to continue with their standard discharge practices of written communication.

    Mamun, Muhammad Z; Andaleeb, Syed Saad

    2013-01-01

    The growing trend of Bangladeshi patients travelling abroad for medical services has led to some soul-searching in policy circles. While other countries of the Southeast Asia region are profiting from medical tourism, Bangladesh not only lags behind, it also loses patients to these countries in a continuous stream. This exodus for medical treatment is seemingly driven by the higher perceived quality of treatment abroad, despite the fact that similar treatment is available more cost-effectively within the country. Certainly the Bangladesh health care system is not without its problenis, which have diminished the perception of quality in the sector. Thus, this study focuses on key factors for Bangladeshi health service providers to address. By doing so, they will be better able to develop the local health care sector and retain Bangladeshi patients within the country. Subsequently, by identifying strategic niches, Bangladesh could focus on delivering higher quality health care services to develop medical tourism and attract patients from abroad in specific categories of health care.

    Full Text Available A review of the history of medicine was conducted in order to evaluate the evolution of “diagnosis” and it was concluded that it was firstly defined by Hippocrates almost two thousand and five hundred years ago. The evolution of the concept is analyzed according to the scientific developments of each epoch. Different methods and their stages to obtain a diagnose are exposed. Similarities of the scientific and clinical methods are analyzed, as a necessary procedure for a good medical diagnosis. Different forms of doctor patient relationship are described, as an essential step for an accurate diagnosis. Medicine is approached as a totally uncertain, probabilistic science aimed to a final diagnosis. It is also emphasized that scientific and technological development bring us adequate tools for taking better decisions in order to facilitate medical diagnosis and its confrontation, not only in a single patient but in the analysis of its effectiveness in groups and communities. Basic pieces of advice are provided on how to obtain diagnoses in daily medical practice. Finally, two patterns in medical procedures are exposed: the Galenic and the Hippocratic.

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

    Antibiotic resistance is a significant public health problem. Prudent use of antibiotics is crucial in reducing this resistance. Acute bronchitis is a common reason for consultations with general medical practitioners, and antibiotics are often prescribed even though guidelines recommend not prescribing them for uncomplicated acute bronchitis. To analyse the antibiotic prescription patterns of South African (SA) general medical practitioners in the treatment of acute bronchitis. The 2013 claims for members of 11 health insurance schemes were analysed to assess antibiotic prescription patterns for patients diagnosed with acute bronchitis. The patterns were assessed by type of bronchitis, chronic health status of the patients, sex and age group. The types of antibiotic prescribed were also analysed. Of 166 821 events analysed, an antibiotic was prescribed in more than half (52.9%). There were significant differences by type of bronchitis and chronic health status. Patients with viral bronchitis were more likely to be prescribed an antibiotic than those with bacterial bronchitis (odds ratio (OR) 1.17, 95% confidence interval (CI) 1.08 - 1.26). Patients with a chronic illness were less likely to be prescribed an antibiotic than those without (OR 0.58, 95% CI 0.57 - 0.60). More than 70% of the antibiotics prescribed were cephalosporins, penicillins and other beta-lactams. Prescription rates of antibiotics for acute bronchitis by SA general medical practitioners are high. There is an urgent need to follow the guidelines for antibiotic use for acute bronchitis to reduce the likelihood of increasing resistance to available antibiotics.

    Objective To investigate the status quo of medical care and public health services provided by general practitioners ( GPs ) in Beijing. Methods Fifty - three GP trainees who attended the general practice job - transfer training and community faculty training in Beijing were surveyed in November 2012 using self - designed questionnaire. Results The most frequently provided medical care services were diagnosis and treatment of common diseases ( 100. 0% ), referral ( 54.1% ), home visit ( 45. 3% ), emergency care ( 39. 6% ), etc. Public health services provided by the investigated GPs in the past 2 weeks were management of health information ( 90. 6% ), management of chronic diseases ( 66. 0% ), geriatric care ( 54.1% ), and health education ( 54. 7% ). Twenty - two out of 53 GPs undertook managerial work, such as statistical report and epidemiologi-cal survey. Inappropriate working time distribution ( 41/53, 77.4% ), unreasonable managerial responsibilities ( 26/53, 49. 1% ), unclear scope of practice ( 52/53, 98. 1% ), inappropriate division of labor in community health service team ( 50/ 53, 94. 3% ) were the major problems raised by the GPs. Thirty - seven ( 74. 0% ) of the GPs thought family planning, management of psychiatric patients, and women health care should be undertaken by public health physicians, and 16 ( 30. 2% ) of the GPs thought management of health information should not be their responsibility. Conclusion There're no defined standards for medical care and public health service provided by GPs. The responsibility and labor division of health professionals in community health service team should be defined. The practice scope of GPs and standardization of service will be a critical research field in general practice.%目的 了解北京市全科医生基本医疗和基本公共卫生服务的提供现状及存在的问题,为北京市完善全科医生工作相关政策提供参考.方法 采用自制调查问卷,对2012年11月参加北京市全

  4. Who was Akilaos? A problem in medical historiography.

    Science.gov (United States)

    Irvine, Judith T; Temkin, Owsei

    2003-01-01

    In the years before the conquest of Alexandria by the Arabs in 642, Alexandrian scholars produced compendia, summaries, and commentaries on Galen's writings and other works in the Hippocratic medical tradition. This paper concerns the identities of those Alexandrian commentators-two in particular, whose names are reported in Arabic texts, but about whom little else is known-and the routes by which Galenic medicine was transmitted to other parts of the Mediterranean world after Alexandria's fall. We review debates over the identity of "Akilaos" and "Anqilaos," and argue that "Akilaos" is not merely a scribal duplication, as some have supposed. Instead, we suggest a connection with the city of Aquileia in northern Italy, as a source for the name "Akilaos" and as a route by which Alexandrian medical texts reached northern Italy (where their Latin versions subsequently were associated with a "Ravenna school" of medicine).

    2011-01-01

    The growth-fragmentation equation arises in many different contexts, ranging from cell division, protein polymerization, biopolymers, neurosciences etc. Direct observation of temporal dynamics being often difficult, it is of main interest to develop theoretical and numerical methods to recover reaction rates and parameters of the equation from indirect observation of the solution. Following the work done in (Perthame, Zubelli, 2006) and (Doumic, Perthame, Zubelli, 2009) for the specific case of the cell division equation, we address here the general question of recovering the fragmentation rate of the equation from the observation of the time-asymptotic solution, when the fragmentation kernel and the growth rates are fully general. We give both theoretical results and numerical methods, and discuss the remaining issues.

  8. Neurotoxicity of general anesthetics: A modern view of the problem

    Directory of Open Access Journals (Sweden)

    A. M. Ovezov

    2015-01-01

    Full Text Available All general anesthetics routinely used in clinical practice are noted to have a neurotoxic effect on the brain in different animal species including primates. The negative effects observed both in young and sexually mature animals include apoptotic neuronal cell death, suppression of neurogenesis and gliogenesis, neuroinflammation, as well as learning and memory impairments. A number of epidemiologic surveys have established an association between anesthesia in patients younger than 3 to 4 years and subsequent learning disabilities and language disorders whereas others have not found this link. In middle-aged and elderly patients, anesthesia is frequently associated with the development of postoperative cognitive dysfunction. The key component of its pathogenesis (general anesthesia itself or other factors, such as operative injury, an inflammatory response, pain syndrome, intraoperative complications, underlying disease in a patient remains unelucidated. It is concluded that there is a need for additional experimental and clinical studies of the pathogenesis of these undesirable phenomena to be prevented and corrected.

    One of the methods for solving mixed problems is the classical separation of variables (the Fourier method). If the boundary conditions of the mixed problem are irregular, this method, generally speaking, is not applicable. In the present paper, a generalized separation of variables and a way of application of this method to solving some mixed problems with irregular boundary conditions are proposed. Analytical representation of the solution to this irregular mixed problem is obtained.

    Problem-based learning (PBL) is a teaching-learning process or method of instruction that is widely used in medical education curricula. Librarians play important roles as facilitators for PBL as well as guides for information resources. Involvement in PBL activities presents unique opportunities to incorporate library resources and instruction into the medical curriculum. This article reviews the problem-based learning method within the conceptual framework of the learning theory of constructivism. It describes how a medical librarian at a U.S. medical school used emerging technologies to facilitate PBL small group case discussions, guide students to quality information resources, and enhance the learning environment for the PBL process.

    2008-12-01

    Patients presenting to an Emergency Department with an altered mental state, whether from a psychiatric, medical or surgical condition or a combination of psychiatric and medical or surgical conditions, require more than the usual amount of diagnostic acumen. General medical conditions often appear in the guise of dysfunctional emotions and/or behaviors. Acute and chronic psychosis may mask underlying acute and chronic medical and surgical conditions. As the case of Esmin Green of Brooklyn, New York, illustrates, the failure to identify underlying medical and surgical conditions in delirious, demented, or psychotic patients can prove fatal to the patient and economically costly to the medical center and its employees.

    Contemporary way of living accompanied by everday frustrations, a frequent use of medicaments, an easy application of corticosteroids, complexity of an opeation, so as an increased incidence of polytraumas --those are the factors responsible for an increasing rate of stress ulcus. The rate of 54 verified stress ulcus in the period from 1969-1979 in Regional Medical Centre of Banja Luka, at Surgical Department, are very often indicative of this disease. Thirty eight operatively treated patients are indicative of severity of this disease. The authors are reporting their experiences in resolving this disease by method of vagotomy with partial gastrectomy in comparison to simple sutures of acutely developed ulcus in addition to PS vagotomy. Perforation, which has, usually, been bigger than the chronic ulcus, we had in 31 cases. If the reports of the world authors are reliable, perforation occurs in 5% of cases only, therefore it is clear how many such conditions has remained undetected or treated under various other "working" diagnoses: (DIC, consumer coagulopathy, fibrinolysis, etc.". The stress ulcus is the disease which is a danger to any patient at Surgical Department.

    The personality profiles of patients with eating disorder have been extensively investigated, but those of people in the general population with eating behavior problems need to be evaluated to assess the relationship between personality, health behavior and level of overall well-being in non-clinical samples. Temperament and character traits, reasons for over-eating, and the negative influence of functional dyspepsia on quality of life were measured by the Temperament and Character Inventory (TCI), Dutch Eating Behavior Questionnaire (DEBQ), and Functional Dyspepsia Quality of Life (FDQOL) inventory, respectively, in 199 Korean medical students. The associations among TCI, FDQOL, DEBQ and body mass index (BMI) were examined by correlational analysis. Multiple regression analysis was carried out to measure how well personality (TCI) accounted for patterns of overeating (DEBQ) and impaired quality of life from functional dyspepsia (FDQOL). Individual differences in personality (especially harm-avoidance, self-transcendence, and self-directedness) were weakly associated with overeating and impaired quality of life from functional dyspepsia. Gender, social desirability and body mass index also played important roles in predicting eating behavior problems in the nonclinical population. We found that the personality traits observed in clinical patients with eating disorders are also found in people with eating behavior problems in the nonclinical population of Korea. The ways that personality traits affect eating behaviors were discussed along with recommendations for future studies in light of the limitations of available data. Copyright © 2015 Elsevier Inc.

    Full Text Available In Poland, stand species compositions are in 43% consistent, in 38% – partially consistent and in 19% - inconsistent with the silvicultural stand type and, therefore, forest reconstruction is a significant and important task for foresters. The study presents the problem of stand reconstruction from the point of view of forest management (regulation, stand stability, concept of reconstruction planning and explains how the concept of stand and forest reconstruction is understood in Poland. Recommended examples of solutions in the field of stand reconstruction were indicated. Criteria of stand assignment for reconstruction, as well as methods of its realisation were discussed from the point of view of successive instructions of forest management and in the light of concepts from different research centres (Poznań, Cracow and Warsaw. The forest reconstruction system and the way of regulation of the final cutting applied within its framework were discussed. Differences in the approach to reconstruction from the point of view of the forest management instruction (2003 and principles of forest silviculture (2003 were indicated.

    Pongsakorn Sunthrayuth

    2012-01-01

    Full Text Available We introduce a new general system of generalized nonlinear mixed composite-type equilibria and propose a new iterative scheme for finding a common element of the set of solutions of a generalized equilibrium problem, the set of solutions of a general system of generalized nonlinear mixed composite-type equilibria, and the set of fixed points of a countable family of strict pseudocontraction mappings. Furthermore, we prove the strong convergence theorem of the purposed iterative scheme in a real Hilbert space. As applications, we apply our results to solve a certain minimization problem related to a strongly positive bounded linear operator. Finally, we also give a numerical example which supports our results. The results obtained in this paper extend the recent ones announced by many others.

    Full Text Available INTRODUCTION: General practice is under-represented in student career choices. This study aimed to identify and explore factors that influence the attitudes of final year medical students to general practice as a career. METHODS: This qualitative study used semi-structured interviews of focus groups of final year undergraduate medical students at the University of Otago, Christchurch, New Zealand. Thematic analysis and grounded theory were used to interpret the data. FINDINGS: General practitioners (GPs play a key role in influencing medical students’ attitudes to general practice as a career. Students identified their general practice placement during medical school training and personal contact with their own GP as principal factors. The media portrayal of general practice and the attitudes of friends and family were also influential. Students were positively influenced when they were made to feel part of the team, involved with consultations, allowed to carry out practical procedures under supervision, and witnessed what they perceived as good medical practice during clinical placements. Positive experiences often occurred later in training, when students felt more confident of their clinical abilities. While students reported occasional negative comments about general practice by some hospital doctors, these had a lesser role in influencing their perceptions of general practice compared with their own experiences, both as students and patients. CONCLUSION: GPs have a strong influence, positively and negatively, on the attitudes of medical students to general practice as a career. Effective influences include being made to feel welcome, involved, valued, and given legitimate roles during clinical placements.

  8. An analytic approach to resolving problems in medical ethics.

    Education in ethics among practising professionals should provide a systematic procedure for resolving moral problems. A method for such decision-making is outlined using the two classical orientations in moral philosophy, teleology and deontology. Teleological views such as utilitarianism resolve moral dilemmas by calculating the excess of good over harm expected to be produced by each feasible alternative for action. The deontological view focuses on rights, duties, and principles of justice. Both methods are used to resolve the 1971 Johns Hopkins case of a baby born with Down's syndrome and duodenal atresia.

    The principal purpose of this paper is to present a comprehensive overview of generalized information theory (GIT): a research program whose objective is to develop a broad treatment of uncertainty-based information, not restricted to classical notions of uncertainty. After a brief overview of classical information theories, a broad framework for formalizing uncertainty and the associated uncertainty-based information of a great spectrum of conceivable types is sketched. The various theories of imprecise probabilities that have already been developed within this framework are then surveyed, focusing primarily on some important unifying principles applying to all these theories. This is followed by introducing two higher levels of the theories of imprecise probabilities: (i) the level of measuring the amount of relevant uncertainty (predictive, retrodictive, prescriptive, diagnostic, etc.) in any situation formalizable in each given theory, and (ii) the level of some methodological principles of uncertainty, which are contingent upon the capability to measure uncertainty and the associated uncertainty-based information. Various issues regarding both the measurement of uncertainty and the uncertainty principles are discussed. Again, the focus is on unifying principles applicable to all the theories. Finally, the current status of GIT is assessed and future research in the area is discussed.

    Problem oriented medical record (POMR) was born in late sixties. Expecting an ordered, complete and updated medical record were some of the goals of its founder. Several healthcare institutions have included problem list into their clinical records but some concerns have been reported. These concerns are in reference to their voluminosity, incompleteness and outdatedness. This study attempts to understand how healthcare professionals are using the problem list at Hospital Italiano de Buenos Aires (HIBA). We believe it is essential to understand the local reality applied to our own applications and cultural instances of documentation. This report is the basis from which several improvements could be made in order to meet the goals of Weed's proposal.

    Heart transplantation remains the treatment of choice in selected patients with severe heart failure (HF) despite optimal medical therapy. Since long-term survival after HTX is improving, there is a growing need for evidence-based strategies that reduce long-term mortality resulting from both immunological and non-immunological risk. This manuscript summarizes recommendations for treatment of transplant vasculopathy, malignancy after transplantation, and prevention of corticosteroid induced bone disease. Based on actual understanding of cardiovascular risk factors in the population, preservation of renal function, prevention and treatment of hyperlipidemia and diabetes, as well as blood pressure control play an important role in the long-term follow-up after heart transplantation.

    Medication reconciliation problems are common among older adults at hospital discharge and lead to adverse events. The purpose of this study was to examine the rates and types of medication reconciliation problems among older adults hospitalized for acute episodes of heart failure who were discharged home. This secondary analysis of data generated from a transitional care intervention included 198 hospital discharge medical records, representing 162 patients. A retrospective chart review comparing medication lists between hospital discharge summaries and patient discharge instructions was completed to identify medication reconciliation problems. Most hospital discharges (71.2%) had at least one type of reconciliation problem and frequently involved a high-risk medication (76.6%). Discrepancies were the most common problem (58.9%), followed by incomplete discharge summaries (52.5%) and partial patient discharge instructions (48.9%). More attention needs to be given to the quality of discharge instructions, and the problem of vague phrases (e.g., "take as directed") can be addressed by adding it to "do not use" lists to promote safer transitions in care.

  15. On Wyner-Ziv Problem for general sources with average distortion criterion

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The Wyner-Ziv Problem for general sources with average distortion under fixed-length coding is investigated in this paper. To solve the problem, an enhanced covering lemma for a Markov chain is first established. Then based on the lemma, a general formula for the rate-distortion function of the problem is derived, where the distortion is only assumed uniformly bounded and may be nonadditive. Finally, it is further pointed out that such methods can be used to establish more general results on multiterminal source coding problems.

    2006-01-01

    A new class of generalized mixed implicit quasi-equilibrium problems (GMIQEP) with four-functions is introduced and studied. The new class of equilibrium problems includes many known generalized equilibrium problems and generalized mixed implicit quasi-variational inequality problems as many special cases. By employing the auxiliary principle technique, some predictor-corrector iterative algorithms for solving the GMIQEP are suggested and analyzed. The convergence of the suggested algorithm only requires the continuity and the partially relaxed implicit strong monotonicity of the mappings.

    The structural dynamics problems, such as structural design, parameter identification and model correction, are considered as a kind of the inverse generalized eigenvalue problems mathematically. The inverse eigenvalue problems are nonlinear. In general, they could be transformed into nonlinear equations to solve. The structural dynamics inverse problems were treated as quasi multiplicative inverse eigenalue problems which were solved by homotopy method for nonlinear equations. This method had no requirements for initial value essentially because of the homotopy path to solution. Numerical examples were presented to illustrate the homotopy method.

    Full Text Available In this paper, a new hybrid iterative algorithm is constructed using the shrinking projection method introduced by Takahashi. The sequence of the algorithm is proved to converge strongly to a common element of the set of solutions of generalized mixed equilibrium problem and the set of common fixed points of a finite family of multivalued strictly pseudocontractive mappings in real Hilbert spaces. Furthermore, we apply our main result to convex minimization problem.

    Background Health care is increasingly provided in general practice. To meet this demand, the English Department of Health recommends that 50% of all medical students should train for general practice after qualification. Currently 19% of medical students express general practice as their first career choice. Undergraduate exposure to general practice positively influences future career choice. Appropriate undergraduate exposure to general practice is therefore highly relevant to workforce planning Aim This study seeks to quantify current exposure of medical students to general practice and compare it with past provision and also with postgraduate provision. Design and setting A cross-sectional questionnaire in the UK. Method A questionnaire regarding provision of undergraduate teaching was sent to the general practice teaching leads in all UK medical schools. Information was gathered on the amount of undergraduate teaching, how this was supported financially, and whether there was an integrated department of general practice. The data were then compared with results from previous studies of teaching provision. The provision of postgraduate teaching in general practice was also examined. Results General practice teaching for medical students increased from teaching in 1968 to 13.0% by 2008; since then, the percentage has plateaued. The total amount of general practice teaching per student has fallen by 2 weeks since 2002. Medical schools providing financial data delivered 14.6% of the clinical curriculum and received 7.1% of clinical teaching funding. The number of departments of general practice has halved since 2002. Provision of postgraduate teaching has tripled since 2000. Conclusion Current levels of undergraduate teaching in general practice are too low to fulfil future workforce requirements and may be falling. Financial support for current teaching is disproportionately low and the mechanism counterproductive. Central intervention may be required to solve

    To determine whether general practitioners learned better with task-based learning or problem-oriented lecture in a Continuing Medical Education (CME) set-up. Quasi-experimental study. The Aga Khan University, Karachi campus, from April to June 2012. Fifty-nine physicians were given a choice to opt for either Task-based Learning (TBL) or Problem Oriented Lecture (PBL) in a continuing medical education set-up about headaches. The TBL group had 30 participants divided into 10 small groups, and were assigned case-based tasks. The lecture group had 29 participants. Both groups were given a pre and a post-test. Pre/post assessment was done using one-best MCQs. The reliability coefficient of scores for both the groups was estimated through Cronbach's alpha. An item analysis for difficulty and discriminatory indices was calculated for both the groups. Paired t-test was used to determine the difference between pre- and post-test scores of both groups. Independent t-test was used to compare the impact of the two teaching methods in terms of learning through scores produced by MCQ test. Cronbach's alpha was 0.672 for the lecture group and 0.881 for TBL group. Item analysis for difficulty (p) and discriminatory indexes (d) was obtained for both groups. The results for the lecture group showed pre-test (p) = 42% vs. post-test (p) = 43%; pre- test (d) = 0.60 vs. post-test (d) = 0.40. The TBL group showed pre -test (p) = 48% vs. post-test (p) = 70%; pre-test (d) = 0.69 vs. post-test (d) = 0.73. Lecture group pre-/post-test mean scores were (8.52 ± 2.95 vs. 12.41 ± 2.65; p learning through TBL delivery and calls for further exploration of longitudinal studies in the context of CME.

    2014-01-01

    Full Text Available In medical datasets classification, support vector machine (SVM is considered to be one of the most successful methods. However, most of the real-world medical datasets usually contain some outliers/noise and data often have class imbalance problems. In this paper, a fuzzy support machine (FSVM for the class imbalance problem (called FSVM-CIP is presented, which can be seen as a modified class of FSVM by extending manifold regularization and assigning two misclassification costs for two classes. The proposed FSVM-CIP can be used to handle the class imbalance problem in the presence of outliers/noise, and enhance the locality maximum margin. Five real-world medical datasets, breast, heart, hepatitis, BUPA liver, and pima diabetes, from the UCI medical database are employed to illustrate the method presented in this paper. Experimental results on these datasets show the outperformed or comparable effectiveness of FSVM-CIP.

    Transitions between the outpatient and inpatient sector are a critical phase in medication treatment. This article provides an overview of published problem areas and examples of best practice in the intersectoral medication treatment. Data with regard to related problem areas and examples of best practice was collected in August 2011 by a systematic literature research. The relevant literature was identified using the following databases and search engines: MEDLINE, The Cochrane Library, EMBASE, Google, and Google Scholar. Additionally, a hand search was done on the websites of SpringerLink and Thieme Connect. The initial search yielded a total of 4,409 records which were further selected in two screening steps and analysed according to their relevance. Of the remaining 63 records, 3 exclusively described problem areas, 11 of them examples of best practice, and 49 provided information on both problem areas and examples of best practice with regard to intersectoral medication treatment. Among other things, problem areas include varying legal regulations in inpatient and outpatient medication treatment, drug therapy interruptions after hospital discharge, or deficits in communication and continuity of care. Examples of best practice are projects, programmes, initiatives, recommendations, and points to consider with respect to medication reconciliation, pharmaceutical support, or transitions of care. Problem areas as well as examples of best practice are mainly focused on the transition from inpatient to outpatient care.

    Problem based learning (PBL) is an instructional approach that utilizes problems or cases as a context for students to acquire problem solving skills. It promotes communication skills, active learning, and critical thinking skills. It encourages peer teaching and active participation in a group. It was a cross-sectional study conducted at Al Nafees Medical College, Isra University, Islamabad, in one month duration. This study was conducted on 193 students of both 1st and 2nd year MBBS. Each PBL consists of three sessions, spaced by 2-3 days. In the first session students were provided a PBL case developed by both basic and clinical science faculty. In Session 2 (group discussion), they share, integrate their knowledge with the group and Wrap up (third session), was concluded at the end. A questionnaire based survey was conducted to find out overall effectiveness of PBL sessions. Teaching through PBLs greatly improved the problem solving and critical reasoning skills with 60% students of first year and 71% of 2nd year agreeing that the acquisition of knowledge and its application in solving multiple choice questions (MCQs) was greatly improved by these sessions. They observed that their self-directed learning, intrinsic motivation and skills to relate basic concepts with clinical reasoning which involves higher order thinking have greatly enhanced. Students found PBLs as an effective strategy to promote teamwork and critical thinking skills. PBL is an effective method to improve critical thinking and problem solving skills among medical students.

    2014-01-01

    Full Text Available We first introduce and analyze one multistep iterative algorithm by hybrid shrinking projection method for finding a solution of the system of generalized equilibria with constraints of several problems: the generalized mixed equilibrium problem, finitely many variational inclusions, the minimization problem for a convex and continuously Fréchet differentiable functional, and the fixed-point problem of an asymptotically strict pseudocontractive mapping in the intermediate sense in a real Hilbert space. We prove strong convergence theorem for the iterative algorithm under suitable conditions. On the other hand, we also propose another multistep iterative algorithm involving no shrinking projection method and derive its weak convergence under mild assumptions.

    2010-01-01

    We present a path algorithm for least squares problems with generalized $\\ell_1$ penalties. This includes as a special case the lasso and fused lasso problems. The algorithm is based on solving the (equivalent) Lagrange dual problem, an approach which offers both a computational advantage and an interesting geometric interpretation of the solution path. Using insights gathered from the dual formulation, we study degrees of freedom for the generalized problem, and develop an unbiased estimate of the degrees of freedom of the fused lasso fit. Our approach bears similarities to least angle regression (LARS), and a simple modification to our method gives the LARS procedure exactly.

    Family physicians provide the majority of elderly patient care in Canada. Many experience significant challenges in serving this cohort. This study aimed to examine the medical problems of patients referred to a care of the elderly physician, to better understand the geriatric continuing medical education (CME) needs of family doctors. A retrospective chart review of patients assessed at an urban outpatient seniors' clinic between 2003 and 2008 was conducted. Data from 104 charts were analyzed and survey follow-up with 28 of the referring family physicians was undertaken. Main outcomes include the type and frequency of medical problems actually referred to a care of the elderly physician. Clarification of future geriatric CME topics of need was also assessed. Preventive care issues were addressed with 67 patients. Twenty-four required discussion of advance directives. The most common medical problems encountered were osteoarthritis (42), hypertension (34), osteoporosis (32), and depression or anxiety (23). Other common problems encountered that have not been highly cited as being a target of CME included musculoskeletal and joint pain (41), diabetes (23), neck and back pain (20), obesity (11), insomnia (11), and neuropathic, fibromyalgia and "leg cramps" pain (10). The referring family physicians surveyed agreed that these were topics of need for future CME. The findings support geriatric CME for the common medical problems encountered. Chronic pain, diabetes, obesity and insomnia continue to be important unresolved issues previously unacknowledged by physicians as CME topics of need. Future CME focusing more on process of geriatric care may also be relevant.

  3. Sources of Stress and Coping Strategies among Undergraduate Medical Students Enrolled in a Problem-Based Learning Curriculum

    Full Text Available Background. Medical education is rated as one of the most difficult trainings to endure. Throughout their undergraduate years, medical students face numerous stressors. Coping with these stressors requires access to a variety of resources, varying from personal strengths to social support. We aimed to explore the perceived stress, stressors, and coping strategies employed by medical students studying in a problem-based learning curriculum. Methodology. This is a cross-sectional study of randomly selected medical students that explored demographics, perceived stress scale, sources of stress, and coping strategies. Results. Of the 378 medical students that participated in the study, males were 59.3% and females 40.7%. Nearly 53% of the students often felt stressed, and a third felt that they could not cope with stress. Over 82% found studying stressful and 64.3% were not sleeping well. Half of the students reported low self-esteem. Perceived stress scores were statistically significantly high for specific stressors of studying in general, worrying about future, interpersonal conflict, and having low self-esteem. Coping strategies that were statistically significantly applied more often were blaming oneself and being self-critical, seeking advice and help from others, and finding comfort in religion. Female students were more stressed than males but they employ more coping strategies as well. Conclusions. Stress is very common among medical students. Most of the stressors are from coursework and interpersonal relationships. Low self-esteem coupled with self-blame and self-criticism is quite common.

    The benefits of the availability and use of medical equipment for medical outcomes are understood by physicians and policymakers alike. However, there is limited understanding of the decision-making processes involved in adopting and using new technologies in health care organisations. Our study focuses on the adoption of medical equipment in Irish general practices which are marked by considerable autonomy in terms of commercial practice and the range of medical services they provide. We examine the adoption of six items of medical equipment taking into account commercial, informational and experiential stimuli. Our analysis is based on primary survey data collected from a sample of 601 general practices in Ireland on practice characteristics and medical equipment use. We use a multivariate Probit to identify commonalities in the determinants of the adoption. Many factors, such as GP and practice characteristics, influence medical equipment adoption. In addition, we find significant and consistent evidence of the influence of learning-by-using effects on the adoption of medical equipment in a general practice setting. Knowledge generated by experiential or applied learning can have commercial, organisational and health care provision benefits in small health care organisations.

    Electroconvulsive therapy (ECT) is safe and effective for the treatment of various psychiatric disorders. Despite being a well-known treatment method among health care professionals, lay people generally have a negative opinion of ECT. The present study aimed to examine knowledge of and attitudes toward ECT among medical students, psychology students, and the general public. Psychology students were included because they are among the important groups in mental health care in Turkey. A Likert-type questionnaire was administered to fifth-year medical students (n = 28), master of science and doctor of philosophy clinical psychology students (n = 35), and a sample of the general public (n = 26). The questionnaire included questions about the general principles of and indications for ECT, and sources of knowledge of and attitudes toward ECT. The medical students were the most knowledgeable about ECT, as expected. The medical students also had a more positive attitude toward ECT than the other 2 groups. More psychology students had negative attitudes on some aspects than general public sample, despite being more knowledgeable. Medical school theoretical and practical training in ECT played an important role in increasing the level of knowledge of and decreasing the prevalence of negative attitudes toward ECT among the medical students; similar training for psychology students is required to achieve similar results.

  7. And that is Where the Fun Ends - General Practitioners' Conceptualisation of the Line Between Recreational and Problem Gambling

    2015-03-01

    Full Text Available AIMS - Problem gambling is normally identified by fixed criteria of harm adapted from those of substance abuse and by focusing on the individual gambler. However, rigid definitions neglect institutional variations of gambling practices within different legislative configurations. This study proposes analysing the line between recreational and problem gambling by focusing on gambling behaviour and looking at the corruption of the defining factors of play (Cail-lois, 1958 in three different institutional contexts. DESIGN - A stimulated focus-group method (Reception Analytical Group Interview was applied to seven groups of Finnish and French general practitioners each and three groups of German ones to study the variations of conceptualising the defining factors of play as introduced by Caillois. RESULTS - Corruption of play was distinguished by participants from all three countries as the dividing line between recreational and problem gambling, but cultural variations were found: the French and German GPs emphasised the loss of the exceptionality of gambling, whereas the Finnish GPs highlighted the invasion of the home by online gambling. Furthermore, the Finnish and German participants were more concerned about the use of gambling as an emotional regulator, while French GPs echoed the French medical model in discussing the adrenaline rush of problem gamblers. CONCLUSIONS - Caillois' defining factors of play can be used to distinguish recreational from problem gambling and to offer a more encompassing definition of problem gambling. The perception of the line between recreational and problem gambling also seems to depend on the institutional and cultural context.

  8. General theory of spherically symmetric boundary-value problems of the linear transport theory.

    Science.gov (United States)

    Kanal, M.

    1972-01-01

    A general theory of spherically symmetric boundary-value problems of the one-speed neutron transport theory is presented. The formulation is also applicable to the 'gray' problems of radiative transfer. The Green's function for the purely absorbing medium is utilized in obtaining the normal mode expansion of the angular densities for both interior and exterior problems. As the integral equations for unknown coefficients are regular, a general class of reduction operators is introduced to reduce such regular integral equations to singular ones with a Cauchy-type kernel. Such operators then permit one to solve the singular integral equations by the standard techniques due to Muskhelishvili. We discuss several spherically symmetric problems. However, the treatment is kept sufficiently general to deal with problems lacking azimuthal symmetry. In particular the procedure seems to work for regions whose boundary coincides with one of the coordinate surfaces for which the Helmholtz equation is separable.

    The problem of general Radon representation is as follows. Given a Hausdorff topological space, find the space of linear functionals that are representable as integrals over all Radon measures. One of the possible solutions of this problem was obtained in Part I of this paper. In Part II we establish that the classical theorems of Riesz-Radon and Prokhorov are corollaries of the theorem on general integral Radon representation.

    1999-05-01

    All proposals for a reform of the study of medicine recommend problem-based teaching and learning methods. The rapid increase in the number of medical faculties abroad offering experimental courses along these lines is an indicator of their usefulness. The results of empirical research also suggest that departments of medical psychology, psychosomatic medicine and psychotherapy should participate more closely in the introduction and exploration of the advantages of this didactic approach.

  16. Choreographic solution to the general-relativistic three-body problem.

    Imai, Tatsunori; Chiba, Takamasa; Asada, Hideki

    2007-05-18

    We reexamine the three-body problem in the framework of general relativity. The Newtonian N-body problem admits choreographic solutions, where a solution is called choreographic if every massive particle moves periodically in a single closed orbit. One is a stable figure-eight orbit for a three-body system, which was found first by Moore (1993) and rediscovered with its existence proof by Chenciner and Montgomery (2000). In general relativity, however, the periastron shift prohibits a binary system from orbiting in a single closed curve. Therefore, it is unclear whether general-relativistic effects admit choreography such as the figure eight. We examine general-relativistic corrections to initial conditions so that an orbit for a three-body system can be choreographic and a figure eight. This illustration suggests that the general-relativistic N-body problem also may admit a certain class of choreographic solutions.

    This study ascertained demographic information and prevalence rates of medical problems among 571 new and consecutive dental patients attending the emergency clinic of the School of Dentistry, The University of the West Indies. Patients were interviewed by specially trained and calibrated dental students and interns. Various medical problems of patients were recorded in individual open-ended case sheets, maintaining their privacy and confidentiality. This information was then transcribed into a specially designed and pretested form. The data were entered into a Microsoft Excel spreadsheet and analyzed using the SPSS statistical package to obtain the prevalence rates of medical conditions, which were then cross-tabulated with gender, age, ethnicity, and other variables. Significance of differences, if any, was evaluated by chi-square test. In all, 303 medical conditions were encountered in 239 individuals, giving a prevalence rate of 42 percent. Hypertension (12.6 percent), diabetes (6.1 percent), asthma (5.8 percent), arthritis (4.7 percent), and various allergies (8.3 percent) constituted an important segment of the problems. Gender, ethnic, and age differences were also evident for some diseases. In this study-which was the first of this kind in the West Indies-vital information on medical problems among dental patients was obtained by interviews conducted by dental students and interns, forming an important part of their dental education.

    According to database of medical institutions of health insurance review and assessment service in 2013, 1,118 hospitals and clinics have department of radiology in Korea. And there are CT, fluoroscopic and general radiographic equipment in those hospitals. Above all, general radiographic equipment is the most commonly used in the radiology department. And most of the general radiographic equipment are changing the digital radiography system from the film-screen types of the radiography system nowadays. However, most of the digital radiography department are used the film-screen types of the radiography system. Therefore, in this study, we confirmed present conditions of technical items for general radiography used in hospital and research on general radiographic techniques in domestic medical institutions. We analyzed 26 radiography projection method including chest, skull, spine and pelvis which are generally used in the radiography department.

    There is increasing demand to provide clinical and teaching experiences in the general practice setting. Vertical integration in teaching and learning, whereby teaching and learning roles are shared across all learner stages, has the potential to decrease time demands and stress on general practitioners, to provide teaching skills and experience to GP registrars, and to improve the learning experience for medical students, and may also help meet the increased demand for teaching in general practice. We consider potential advantages and barriers to vertical integration of teaching in general practice, and provide results of focus group discussions with general practice principals and registrars about vertical integration. We recommend further research into the feasibility of using vertical integration to enhance the capacity to teach medical students in general practice.

    2007-01-01

    The well-known Generalized Champagne Problem on simultaneous stabilization of linear systems is solved by using complex analysis and Blondel's technique. We give a complete answer to the open problem proposed by Patel et al., which automatically includes the solution to the original Champagne Problem. Based on the recent development in automated inequality-type theorem proving, a new stabilizing controller design method is established. Our numerical examples significantly improve the relevant results in the literature.

  12. PowerPlay: Training an Increasingly General Problem Solver by Continually Searching for the Simplest Still Unsolvable Problem.

    Science.gov (United States)

    Schmidhuber, Jürgen

    2013-01-01

    Most of computer science focuses on automatically solving given computational problems. I focus on automatically inventing or discovering problems in a way inspired by the playful behavior of animals and humans, to train a more and more general problem solver from scratch in an unsupervised fashion. Consider the infinite set of all computable descriptions of tasks with possibly computable solutions. Given a general problem-solving architecture, at any given time, the novel algorithmic framework PowerPlay (Schmidhuber, 2011) searches the space of possible pairs of new tasks and modifications of the current problem solver, until it finds a more powerful problem solver that provably solves all previously learned tasks plus the new one, while the unmodified predecessor does not. Newly invented tasks may require to achieve a wow-effect by making previously learned skills more efficient such that they require less time and space. New skills may (partially) re-use previously learned skills. The greedy search of typical PowerPlay variants uses time-optimal program search to order candidate pairs of tasks and solver modifications by their conditional computational (time and space) complexity, given the stored experience so far. The new task and its corresponding task-solving skill are those first found and validated. This biases the search toward pairs that can be described compactly and validated quickly. The computational costs of validating new tasks need not grow with task repertoire size. Standard problem solver architectures of personal computers or neural networks tend to generalize by solving numerous tasks outside the self-invented training set; PowerPlay's ongoing search for novelty keeps breaking the generalization abilities of its present solver. This is related to Gödel's sequence of increasingly powerful formal theories based on adding formerly unprovable statements to the axioms without affecting previously provable theorems. The continually increasing

    2016-08-01

    We conducted a review of published medical education articles to identify high-quality research and innovation relevant to educators in general medicine. Our review team consisted of six general internists with expertise in medical education and a professional medical librarian. We manually searched 15 journals in pairs (a total of 3062 citations) for original research articles in medical education published in 2014. Each pair of reviewers independently rated the relevance, importance, and generalizability of articles on medical education in their assigned journals using a 27-point scale (maximum of 9 points for each characteristic). From this list, each team member independently reviewed the 22 articles that received a score of 20 or higher from both initial reviewers, and for each selected article rated the quality and global relevance for the generalist educator. We included the seven top-rated articles for presentation in this review, and categorized the studies into four general themes: continuity clinic scheduling, remediation, interprofessional education, and quality improvement and patient safety. We summarized key findings and identified significant limitations of each study. Further studies assessing patient outcomes are needed to strengthen the literature in medical education. This summary of relevant medical education articles can inform future research, teaching, and practice.

    2014-01-01

    Pharmaceutical advertisements have been argued to provide revenue that medical journals require but they are intended to alter prescribing behaviour and they are known to include low quality information. We determined whether a difference exists in the current level of pharmaceutical advertising in print general medical journals, and we estimated the revenue generated from print pharmaceutical advertising. Six print general medical journals in Canada, the United States, and the United Kingdom were sampled between 2007 and 2012. The number of advertisements and other journal content in selected issues of the Canadian Medical Association Journal (CMAJ), Canadian Family Physician (CFP), Journal of the American Medical Association (JAMA), New England Journal of Medicine (NEJM), British Medical Journal (BMJ), and Lancet were determined. Revenue gained from pharmaceutical advertising was estimated using each journal's 2013 advertising price list. The two Canadian journals sampled (CMAJ, CFP) contained five times more advertisements than the two American journals (JAMA, NEJM), and two British journals (BMJ, Lancet) (pjournals, with the two Canadian journals sampled containing the most advertisements. International and temporal variations suggest that there is an opportunity for all general medical journals to reduce the number of pharmaceutical advertisements, explore other sources of revenue, and increase transparency regarding sources of revenue.

    Diagnostic imaging has been shifted rapidly from film to monitor diagnostic. Consequently, Japan medical imaging and radiological systems industries association (JIRA) have recommended methods of quality control (QC) for medical imaging display systems. However, in spite of its need by majority of people, executing rate is low. The purpose of this study was to validate the problem including check items about QC for medical imaging display systems. We performed acceptance test of medical imaging display monitors based on Japanese engineering standards of radiological apparatus (JESRA) X-0093*A-2005 to 2009, and performed constancy test based on JESRA X-0093*A-2010 from 2010 to 2012. Furthermore, we investigated the cause of trouble and repaired number. Medical imaging display monitors had 23 inappropriate monitors about visual estimation, and all these monitors were not criteria of JESRA about luminance uniformity. Max luminance was significantly lower year-by-year about measurement estimation, and the 29 monitors did not meet the criteria of JESRA about luminance deviation. Repaired number of medical imaging display monitors had 25, and the cause was failure liquid crystal panel. We suggested the problems about medical imaging display systems.

    The purpose of this system is to establish virtual medical school (VMS) as the platform of e-learning center, which integrates collaborative and self-directed learning environment by virtual group, classroom and library, and automatically converts valuable clinical case from Hospital Information System (HIS) database into virtual patient by online authoring tools for problem-based e-learning. In this system, the VMS provides a problem-based e-learning environment, and utilizes HIS to capture and store valuable clinical cases. All medical students and residents now have the opportunity to learn from these typical cases online. The VMS at National Taiwan University has the potential to develop into a national medical education network for the meditation and provision of comprehensive medical resources. The system will use the international standard SCORM 1.2 to develop teaching material and assist with the HL7 v2.4, CDA v1.0 standards to connect Electronic Medical Record (EMR) systems in the hospital. It can provide resources sharing among medical centers by using high transportation ability of Grid Computing integrated with the broadband video platform, Access Grid, and personal multiple point videoconference platform, Multi-video, to popularize the application of e-learning in clinical medical education.

    Full Text Available Background: An association between oral conditions such as periodontal diseases and systemic conditions is noted. As such, periodontal disease is associated with an increased risk of systemic illnesses such as cardiovascular disease, diabetes, adverse pregnancy outcome, atherosclerosis, stroke and hospital acquired pneumonia. The concept of diagnosing and treating a potential patient to minimize the deleterious effects of this chronic infectious and inflammatory condition on systemic conditions represents both an unprecedented challenge and opportunity to our profession. Keeping this in view, the present survey was designed to evaluate the acquaintance, orientation and behavior of general medical practitioners; concerning the effects of periodontal disease on systemic health. Materials and Methods: A typed questionnaire carrying four sets of questions was distributed among general medical practitioners of seven different government and private medical colleges and hospitals. Questionnaire was developed to assess the acquaintance, orientation and behavior of general medical practitioners toward periodontal disease. Results: Most of the respondents have knowledge regarding the signs and symptoms of periodontal disease and its association with cardiovascular disease. However, majority of them do not know about the potential effect of periodontal disease on other organ systems. Conclusion: General medical practitioners have inadequate knowledge regarding periodontal diseases. Hence, oral health related training should be an integral part of the medical curriculum.

    2008-02-01

    When machine learning algorithms are applied to data collected during the course of clinical care, it is generally accepted that the data has not been consistently collected. The absence of expected data elements is common and the mechanism through which a data element is missing often involves the clinical relevance of that data element in a specific patient. Therefore, the absence of data may have information value of its own. In the process of designing an application intended to support a medical problem list, we have studied whether the "missingness" of clinical data can provide useful information in building prediction models. In this study, we experimented with four methods of treating missing values in a clinical data set-two of them explicitly model the absence or "missingness" of data. Each of these data sets were used to build four different kinds of Bayesian classifiers-a naive Bayes structure, a human-composed network structure, and two networks based on structural learning algorithms. We compared the performance between groups with and without explicit models of missingness using the area under the ROC curve. The results showed that in most cases the classifiers trained using the explicit missing value treatments performed better. The result suggests that information may exist in "missingness" itself. Thus, when designing a decision support system, we suggest one consider explicitly representing the presence/absence of data in the underlying logic.

    Full Text Available Abstract In this paper, we introduce a notion of Levitin-Polyak well-posedness for generalized semi-infinite multiobjective programming problems in terms of weakly efficient solutions. We obtain some metric characterizations of Levitin-Polyak well-posedness for this problem. We derive the relations between the Levitin-Polyak well-posedness and the upper semi-continuity of approximate solution maps for generalized semi-infinite multiobjective programming problems. Examples are given to illustrate our main results.

    2005-01-01

    We consider the numbers arising in the problem of normal ordering of expressions in canonical boson creation and annihilation operators. We treat a general form of a boson string which is shown to be associated with generalizations of Stirling and Bell numbers. The recurrence relations and closed-form expressions (Dobiski-type formulas) are obtained for these quantities by both algebraic and combinatorial methods. By extensive use of methods of combinatorial analysis we prove the equivalence of the aforementioned problem to the enumeration of special families of graphs. This link provides a combinatorial interpretation of the numbers arising in this normal ordering problem.

    By applying a maximal element theorem on product FC-space due to author, some new equilibrium existence theorems for generalized games with fuzzy constraint correspondences are proved in FC-spaces. By using these equilibrium existence theorems, some new existence theorems of solutions for the system of generalized vector quasi-equilibrium problems are established in noncompact product FC-spaces. These results improve and generalize some recent results in literature to product FC-spaces without any convexity structure.

    2003-01-01

    Background Hemodialysis (HD) patients are at risk for medication-related problems (MRP). The MRP number, type, and appearance rate over time in ambulatory HD patients has not been investigated. Methods Randomly selected HD patients were enrolled to receive monthly pharmaceutical care visits. At each visit, MRP were identified through review of the patient chart, electronic medical record, patient interview, and communications with other healthcare disciplines. All MRP were categorized by type and medication class. MRP appearance rate was determined as the number of MRP identified per month/number of months in study. The number of MRP per patient-drug exposures were determined using: {[(number of patients) × (mean number of medications)]/(number of months of study)} /number of MRP identified. Results were expressed as mean ± standard deviation or percentages. Results Patients were 62.6 ± 15.9 years old, had 6.4 ± 2.0 comorbid conditions, were taking 12.5 ± 4.2 medications, and 15.7 ± 7.2 doses per day at baseline. Medication-dosing problems (33.5%), adverse drug reactions (20.7%), and an indication that was not currently being treated (13.5%) were the most common MRP. 5,373 medication orders were reviewed and a MRP was identified every 15.2 medication exposures. Overall MRP appearance rate was 0.68 ± 0.46 per patient per month. Conclusion MRP continue to occur at a high rate in ambulatory HD patients. Healthcare providers taking care of HD patients should be aware of this problem and efforts to avoid or resolve MRP should be undertaken at all HD clinics. PMID:14690549

    2016-08-01

    The return to contingency after Operation HERRICK (2002-2014 Afghanistan conflict) has seen an emerging trend for small-scale rapidly developing expeditionary operations. The associated small, remote medical footprint for such operations, often within a coalition construct, reliant on host nation support is in direct conflict with the General Medical Council (GMC) guidelines for junior doctor supervision in an 'approved practice setting'. If a General Duties Medical Officer (GDMO) is nominated to support future operations, the provision of assured patient care and supervision within GMC guidelines, while ensuring career progression and ongoing education, may prove a challenge. Recently published British Army Policy aims to provide a framework to meet these challenges. The authors' first-hand experience in implementing this policy is explored further. The deployment of a remotely supervised GDMO, in line with British Army Policy, is both suitable and safe. This should assure quality medical care delivery during the era of Army Contingency Operations.

    This study examined the impact of social problem-solving training on the behavior of five aggressive boys. Acquisition of problem-solving skills and changes in classroom behavior were evaluated using multiple-baseline designs within and across subjects. A generalization-programming procedure to promote the use of problem-solving skills in the natural environment was introduced across children in multiple-baseline fashion. Direct observation and behavior ratings were used to evaluate the treatment. Results indicated that each subject acquired the problem-solving skills at levels comparable to well-adjusted peers. Only one child showed behavioral improvement coincident with problem-solving skill acquisition. Three others showed moderate behavior change after the generalization-programming procedure was introduced. Only one child's gains on teacher ratings were maintained at the 6-month followup. The results suggest that cognitive-behavioral treatment of childrens' aggressive behavior may produce changes of limited magnitude and durability.

    Full Text Available BACKGROUND: Pharmaceutical advertisements have been argued to provide revenue that medical journals require but they are intended to alter prescribing behaviour and they are known to include low quality information. We determined whether a difference exists in the current level of pharmaceutical advertising in print general medical journals, and we estimated the revenue generated from print pharmaceutical advertising. METHODS: Six print general medical journals in Canada, the United States, and the United Kingdom were sampled between 2007 and 2012. The number of advertisements and other journal content in selected issues of the Canadian Medical Association Journal (CMAJ, Canadian Family Physician (CFP, Journal of the American Medical Association (JAMA, New England Journal of Medicine (NEJM, British Medical Journal (BMJ, and Lancet were determined. Revenue gained from pharmaceutical advertising was estimated using each journal's 2013 advertising price list. FINDINGS: The two Canadian journals sampled (CMAJ, CFP contained five times more advertisements than the two American journals (JAMA, NEJM, and two British journals (BMJ, Lancet (p<0.0001. The estimated annual revenue from pharmaceutical advertisements ranged from £0.025 million (for Lancet to £3.8 million (for JAMA. The cost savings due to revenue from pharmaceutical advertising to each individual subscriber ranged from £0.02 (for Lancet to £3.56 (for CFP per issue. CONCLUSION: The volume of pharmaceutical advertisements differs between general medical journals, with the two Canadian journals sampled containing the most advertisements. International and temporal variations suggest that there is an opportunity for all general medical journals to reduce the number of pharmaceutical advertisements, explore other sources of revenue, and increase transparency regarding sources of revenue.

    DNA computing is a novel method of solving a class of intractable computational problems, in which the computing speeds up exponentially with the problem size. Up to now, many accomplishments have been made to improve its performance and increase its reliability. In this paper, we solved the general form of 0-1 programming problem with fluorescence labeling techniques based on surface chemistry by attempting to apply DNA computing to a programming problem. Our method has some significant advantages such as simple encoding, low cost, and short operating time.

    2013-08-01

    In this paper, we propose a penalty-based recurrent neural network for solving a class of constrained optimization problems with generalized convex objective functions. The model has a simple structure described by using a differential inclusion. It is also applicable for any nonsmooth optimization problem with affine equality and convex inequality constraints, provided that the objective function is regular and pseudoconvex on feasible region of the problem. It is proven herein that the state vector of the proposed neural network globally converges to and stays thereafter in the feasible region in finite time, and converges to the optimal solution set of the problem.

    We are interested in the statistics of the length of the longest increasing subsequence of 2-rowed lexicographically sorted arrays chosen according to distinct families of distributions D = (D_n)_n, and when n goes to infinity. This framework encompasses well studied problems such as the so called Longest Increasing Subsequence problem, the Longest Common Subsequence problem, problems concerning directed bond percolation models, among others. We define several natural families of distinct distributions and characterize the asymptotic behavior of the expected length of a longest increasing subsequence chosen according to them. In particular, we consider generalizations to d-rowed arrays as well as symmetry restricted two-rowed arrays.

    Full Text Available CONTEXT: The reality of medical services in Brazil points towards expansion and diversification of medical knowledge. However, there are few Brazilian studies on choosing a medical specialty. OBJECTIVE: To investigate and characterize the process of choosing the medical specialty among Brazilian resident doctors, with a comparison of the choice between general medicine and surgery. TYPE OF STUDY: Stratified survey. SETTING: Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo (HC-FMUSP. METHODS: A randomized sample of resident doctors in general medicine (30 and surgery (30 was interviewed. Data on sociodemographic characteristics and the moment, stability and reasons for the choice of specialty were obtained. RESULTS: The moment of choice between the two specialties differed. Surgeons (30% choose the specialty earlier, while general doctors decided progressively, mainly during the internship (43%. Most residents in both fields (73% general medicine, 70% surgery said they had considered another specialty before the current choice. The main reasons for general doctors' choice were contact with patients (50%, intellectual activities (30% and knowledge of the field (27%. For surgeons the main reasons were practical intervention (43%, manual activities (43% and the results obtained (40%. Personality was important in the choice for 20% of general doctors and for 27% of surgeons. DISCUSSION: The reasons found for the choice between general medicine and surgery were consistent with the literature. The concepts of wanting to be a general doctor or a surgeon are similar throughout the world. Personality characteristics were an important influencing factor for all residents, without statistical difference between the specialties, as was lifestyle. Remuneration did not appear as a determinant. CONCLUSION: The results from this group of Brazilian resident doctors corroborated data on choosing a medical specialty from other countries

    We conducted a review of articles published in 2013 to identify high-quality research in medical education that was relevant to general medicine education practice. Our review team consisted of six general internists with expertise in medical education of varying ranks, as well as a professional medical librarian. We manually searched 15 journals in pairs, and performed an online search using the PubMed search engine for all original research articles in medical education published in 2013. From the total 4,181 citations identified, we selected 65 articles considered most relevant to general medicine educational practice. Each team member then independently reviewed and rated the quality of each selected article using the modified Medical Education Research Study Quality Instrument. We then reviewed the quality and relevance of each selected study and grouped them into categories of propensity for inclusion. Nineteen studies were felt to be of adequate quality and were of moderate to high propensity for inclusion. Team members then independently voted for studies they felt to be of the highest relevance and quality within the 19 selected studies. The ten articles with the greatest number of votes were included in the review. We categorized the studies into five general themes: Improving Clinical Skills in UME, Inpatient Clinical Teaching Methods, Advancements in Continuity Clinic, Handoffs/Transitions in Care, and Trainee Assessment. Most studies in our review of the 2013 literature in general medical education were limited to single institutions and non-randomized study designs; we identified significant limitations of each study. Selected articles may inform future research and practice of medical educators.

    In medical ultrasound imaging field, in order to obtain high resolution and correct the phase errors induced by the velocity in-homogeneity of the tissue, a high-resolution medical ultrasound imaging method combining minimum variance beamforming and general coherence factor was presented. First, the data from the elements is delayed for focusing; then the multi-channel data is used for minimum variance beamforming; at the same time, the data is transformed from array space to beam space to calculate the general coherence factor; in the end, the general coherence factor is used to weight the results of minimum variance beamforming. The medical images are gotten by the imaging system. Experiments based on point object and anechoic cyst object are used to verify the proposed method. The results show the proposed method in the aspects of resolution, contrast and robustness is better than minimum variance beamforming and conventional beamforming.

    2013-12-01

    As the "Science of Medicine" is getting advanced day-by-day, need for better pedagogies & learning techniques are imperative. Problem Based Learning (PBL) is an effective way of delivering medical education in a coherent, integrated & focused manner. It has several advantages over conventional and age-old teaching methods of routine. It is based on principles of adult learning theory, including student's motivation, encouragement to set goals, think critically about decision making in day-to-day operations. Above all these, it stimulates challenge acceptance and learning curiosity among students and creates pragmatic educational program. To measure the effectiveness of the "Problem Based Learning" as compared to conventional theory/didactic lectures based learning. The study was conducted on 72 medical students from Dayanand Medical College & Hospital, Ludhiana. Two modules of problem based sessions designed and delivered. Pre & Post-test score's scientific statistical analysis was done. Student feed-back received based on questionnaire in the five-point Likert scale format. Significant improvement in overall performance observed. Feedback revealed majority agreement that "Problem-based learning" helped them create interest (88.8 %), better understanding (86%) & promotes self-directed subject learning (91.6 %). Substantial improvement in the post-test scores clearly reveals acceptance of PBL over conventional learning. PBL ensures better practical learning, ability to create interest, subject understanding. It is a modern-day educational strategy, an effective tool to objectively improve the knowledge acquisition in Medical Teaching.

    Adverse drug events represent the most common cause of preventable nonsurgical adverse events in medicine but may remain undetected. Our objective is to determine the proportion of drug-related visits emergency physicians attribute to medication-related problems. This prospective observational study enrolled adults presenting to a tertiary care emergency department (ED) during 12 weeks. Drug-related visits were defined as ED visits caused by adverse drug events. The definition of adverse drug event was varied to examine both narrow and broad adverse drug event classification systems. Clinical pharmacists evaluated all patients for drug-related visits, using standardized assessment algorithms, and then followed patients until hospital discharge. Interrater agreement for the clinical pharmacist diagnosis of drug-related visit was assessed. Emergency physicians, blinded to the clinical pharmacist opinion, were interviewed at the end of each shift to determine whether they attributed the visit to a medication-related problem. An independent committee reviewed and adjudicated all cases in which the emergency physicians' and clinical pharmacists' assessments were discordant, or either the emergency physician or clinical pharmacist was uncertain. The primary outcome was the proportion of drug-related visits attributed to a medication-related problem by emergency physicians. Nine hundred forty-four patients were enrolled, of whom 44 patients received a diagnosis of the narrowest definition of an adverse drug event, an adverse drug reaction (4.7%; 95% confidence interval [CI] 3.5% to 6.2%). Twenty-seven of these were categorized as medication-related by emergency physicians (61.4%; 95% CI 46.5% to 74.3%), 10 were categorized as uncertain (22.7%; 95% CI 12.9% to 37.1%), and 7 categorized as a non-medication-related problem (15.9%; 95% CI 8.0% to 29.5%). Seventy-eight patients (8.3%; 95% CI 6.7% to 10.2%) received a diagnosis of an adverse drug event caused by an adverse drug

    Orthopedic studies are occasionally published in high-impact general medical journals; these studies are often given high visibility and have significant potential to impact health care policy and inform clinical decision-making. The purpose of this review was to investigate the characteristics of operative orthopedic studies published in high-impact medical journals. The number of orthopedic studies published in high-impact medical journals is relatively low; however, these studies demonstrate methodological characteristics that may bias toward nonoperative treatment. Careful analysis and interpretation of orthopedic studies published in these journals is warranted. [Orthopedics. 2017; 40(3):e405-e412.]. Copyright 2017, SLACK Incorporated.

    Full Text Available Introduction: The majority of countries have brought the quality of higher education into focus in the past few years. They have tried to improve the quality of their own higher education. The studies show that Iranian Universities are not at an accepted level in terms of quality. They have encountered several problems which have diminished their quality level. This study aimed at assessing the quality of medical education program as viewed by general practitioners graduated from Shiraz, Fasa and Jahrom Medical Universities. Methods: This is a cross-sectional study. 215 subjects were selected based on a census of all the general practitioners graduated from Shiraz, Fasa and Jahrom Universities during 2011- 2013. The questionnaire used for collecting the data was that of the Association of Graduates from American Medical Colleges. The collected data were then analyzed using SPSS 14 through which such descriptive and bivariate statistics as percentage, means, Standard Deviation and ANOVA were used. The level of significance was set to 0.05. Results: The questionnaire return rate was 97%. As to the graduates’ preclinical experiences, five indices were studied which were assessed as “average” in graduates’ views. However, with respect to their clinical experiences five indices were equally studied, among which such indices as “Communication” were evaluated as “desirable” in view of the graduates from the very three universities. On the contrary, the quality of clinical experiences and technological skills was evaluated as “almost weak”; furthermore, the integration of basic science with required clinical experience was also considered “weak”. Conclusion: It seems essential to set up an annual assessment of general practitioner education program and a review of the medical education program in Iran based on the global medical advancement and international standards.

    2013-01-01

    Full Text Available We present a direct solution technique for approximating linear multiterm fractional differential equations (FDEs on semi-infinite interval, using generalized Laguerre polynomials. We derive the operational matrix of Caputo fractional derivative of the generalized Laguerre polynomials which is applied together with generalized Laguerre tau approximation for implementing a spectral solution of linear multiterm FDEs on semi-infinite interval subject to initial conditions. The generalized Laguerre pseudo-spectral approximation based on the generalized Laguerre operational matrix is investigated to reduce the nonlinear multiterm FDEs and its initial conditions to nonlinear algebraic system, thus greatly simplifying the problem. Through several numerical examples, we confirm the accuracy and performance of the proposed spectral algorithms. Indeed, the methods yield accurate results, and the exact solutions are achieved for some tested problems.

    Eigenvalue problems are ubiquitous in computer vision, covering a very broad spectrum of applications ranging from estimation problems in multi-view geometry to image segmentation. Few other linear algebra problems have a more mature set of numerical routines available and many computer vision libraries leverage such tools extensively. However, the ability to call the underlying solver only as a "black box" can often become restrictive. Many 'human in the loop' settings in vision frequently exploit supervision from an expert, to the extent that the user can be considered a subroutine in the overall system. In other cases, there is additional domain knowledge, side or even partial information that one may want to incorporate within the formulation. In general, regularizing a (generalized) eigenvalue problem with such side information remains difficult. Motivated by these needs, this paper presents an optimization scheme to solve generalized eigenvalue problems (GEP) involving a (nonsmooth) regularizer. We start from an alternative formulation of GEP where the feasibility set of the model involves the Stiefel manifold. The core of this paper presents an end to end stochastic optimization scheme for the resultant problem. We show how this general algorithm enables improved statistical analysis of brain imaging data where the regularizer is derived from other 'views' of the disease pathology, involving clinical measurements and other image-derived representations.

    2008-07-01

    In 2004 a new contract was introduced for General Practitioners in the UK, which introduced a significant element of 'pay-for-performance', including both clinical and organisational targets. The introduction of this contract has caused interest across the world, particularly amongst those responsible for commissioning primary care services. It can be argued that the clinical targets in the contract (known as the Quality and Outcomes Framework, QOF) represent a move towards a more biomedical model of health and illness, which is contrary to the ideal of providing holistic (or biopsychosocial) care that has been traditionally espoused by GPs. This paper reports results from two linked studies (in England and Scotland) investigating the early stages of the new contract. We describe the way in which four practices with different organisational approaches and espoused identities have all changed their practice structures, consultations and clinical care in response to QOF in ways which will result in patients receiving a more biomedical type of care. In spite of these observed changes, respondents continued to maintain discursive claims to holism. We discuss how this disconnection between rhetoric and reality can be maintained, and consider its implications for the future development of GPs' claims to a professional identity.

    Full Text Available Abstract Background Although General Practice (GP was recognized as a medical specialty in Greece in 1986, the number of GPs is insufficient to cover needs and only few medical graduates choose GP as a career option. In the present study we investigated the profile of medical students in terms of their decisions regarding specialization and the possible association of career choices different from GP with the status of undergraduate training regarding GP. Methods The sample consisted of final year students in the Medical School of the University of Athens, Greece. Students filled in a self-reported questionnaire focusing on medical specialization, and GP in particular. Results Response rate was 82.5% with 1021 questionnaires collected, out of 1237 eligible medical students. Only 44 out of the 1021 (4.3% respondents stated that GP is -or could be- among their choices for specialty. The most popular medical specialty was General Surgery (10.9%, followed by Cardiology (9.6%, Endocrinology (8.7% and Obstetrics-Gynaecology (8.3%. The most common criterion for choosing GP was the guaranteed employment on completion of the residency (54.6% while a 56.6% of total respondents were positive to the introduction of GP/FM as a curriculum course during University studies. Conclusion Despite the great needs, GP specialty is currently not a career option among undergraduate students of the greater Medical University in Greece and is still held in low esteem. A university department responsible for undergraduate teaching, promotion and research in GP (where not available is essential; the status of undergraduate training in general practice/family medicine seems to be one of the most important factors that influence physician career choices regarding primary care specialties.

    Objective This study examined general medical illnesses and their association with clinical features of bipolar disorder. Methods Data were cross-sectional and derived from the Lithium Treatment – Moderate Dose Use Study (LiTMUS), which randomized symptomatic adults (n=264 with available medical comorbidity scores) with bipolar disorder to moderate doses of lithium plus optimized treatment (OPT) or to OPT alone. Clinically significant high and low medical comorbidity burden were defined as a Cumulative Illness Rating Scale (CIRS) score ≥ 4 and < 4, respectively. Results The baseline prevalence of significant medical comorbidity was 53% (n=139). Patients with high medical burden were more likely to present in a major depressive episode (P=.04), meet criteria for obsessive-compulsive disorder (P=.02), and experience a greater number of lifetime mood episodes (P=0.02). They were also more likely to be prescribed a greater number of psychotropic medications (P=.002). Sixty-nine percent of the sample was overweight or obese as defined by body mass index (BMI), with African-Americans representing the racial group with the highest proportion of stage II obesity (BMI ≥ 35; 31%, n=14). Conclusions The burden of comorbid medical illnesses was high in this generalizable sample of treatment-seeking patients and appears associated with worsened course of illness and psychotropic medication patterns.

    Integrating pharmacology education into a problem-based learning (PBL) curriculum has proven challenging for many medical schools, including the Pennsylvania State University College of Medicine (Penn State COM). In response to pharmacology content gaps in its PBL-intensive curriculum, Penn State COM in 2003 hired a director of medical pharmacology instruction to oversee efforts to improve the structure of pharmacology education in the absence of a stand-alone course. In this article, the authors describe the ongoing development of the virtual pharmacology curriculum, which weaves pharmacology instruction through the entire medical school curriculum with particular emphasis on the organ-based second year. Pharmacology is taught in a spiraling manner designed to add to and build upon students' knowledge and competency. Key aspects of the virtual curriculum (as of 2011) include clearly stated and behaviorally oriented pharmacology learning objectives, pharmacology study guides that correspond to each PBL case, pharmacology review sessions that feature discussions of United States Medical Licensing Examination (USMLE)-type questions, and pharmacology questions for each PBL case on course examinations to increase student accountability. The authors report a trend toward improved USMLE Step 1 scores since these initiatives were introduced. Furthermore, graduates' ratings of their pharmacology education have improved on the Medical School Graduation Questionnaire. The authors suggest that the initiatives they describe for enhancing pharmacology medical education are relevant to other medical schools that are also seeking ways to better integrate pharmacology into PBL-based curricula.

    2011-04-01

    Full Text Available Abstract Background Several studies showed that blood pressure and lung function are associated. Additionally, a potential effect of antihypertensive medication, especially beta-blockers, on lung function has been discussed. However, side effects of beta-blockers have been investigated mainly in patients with already reduced lung function. Thus, aim of this analysis is to determine whether hypertension and antihypertensive medication have an adverse effect on lung function in a general adult population. Methods Within the population-based KORA F4 study 1319 adults aged 40-65 years performed lung function tests and blood pressure measurements. Additionally, information on anthropometric measurements, medical history and use of antihypertensive medication was available. Multivariable regression models were applied to study the association between blood pressure, antihypertensive medication and lung function. Results High blood pressure as well as antihypertensive medication were associated with lower forced expiratory volume in one second (p = 0.02 respectively p = 0.05; R2: 0.65 and forced vital capacity values (p = 0.01 respectively p = 0.05, R2: 0.73. Furthermore, a detailed analysis of antihypertensive medication pointed out that only the use of beta-blockers was associated with reduced lung function, whereas other antihypertensive medication had no effect on lung function. The adverse effect of beta-blockers was significant for forced vital capacity (p = 0.04; R2: 0.65, while the association with forced expiratory volume in one second showed a trend toward significance (p = 0.07; R2: 0.73. In the same model high blood pressure was associated with reduced forced vital capacity (p = 0.01 and forced expiratory volume in one second (p = 0.03 values, too. Conclusion Our analysis indicates that both high blood pressure and the use of beta-blockers, but not the use of other antihypertensive medication, are associated with reduced lung function in a

    2016-01-01

    We present a systematic methodology for the reformulation of a broad class of three-dimensional (3D) piezoelectric problems into a two-dimensional (2D) mathematical form. The sole underlying hypothesis is that the system geometry and material properties as well as the applied loads (forces and charges) and boundary conditions are translationally invariant along some direction. This class of problems is commonly denoted here as the generalized plane piezoelectric (GPP) problem. The first advantage of the generalized plane problems is that they are more manageable from both analytical and computational points of view. Moreover, they are flexible enough to accommodate any geometric cross section, crystal class symmetry, axis orientation and a wide range of boundary conditions. As an illustration we present numerical simulation of indefinite lattice-mismatched core-shell nanowires made of diamond Ge/Si and zincblende piezoelectric InN/GaN materials. The remarkable agreement with exact 3D simulations of finite ver...

    After the fundamental work of Riesz, Radon and Hausdorff in the period 1909-1914, the following problem of general Radon representation emerged: for any Hausdorff space find the space of linear functionals that are integrally representable by Radon measures. In the early 1950s, a partial solution of this problem (the bijective version) for locally compact spaces was obtained by Halmos, Hewitt, Edwards, Bourbaki and others. For bounded Radon measures on a Tychonoff space, the problem of isomorphic Radon representation was solved in 1956 by Prokhorov. In this paper we give a possible solution of the problem of general Radon representation. To do this, we use the family of metasemicontinuous functions with compact support and the class of thin functionals. We present bijective and isomorphic versions of the solution (Theorems 1 and 2 of §2.5). To get the isomorphic version, we introduce the family of Radon bimeasures.

    Full Text Available Abstract Background To assist educators and researchers in improving the quality of medical research, we surveyed the editors and statistical reviewers of high-impact medical journals to ascertain the most frequent and critical statistical errors in submitted manuscripts. Findings The Editors-in-Chief and statistical reviewers of the 38 medical journals with the highest impact factor in the 2007 Science Journal Citation Report and the 2007 Social Science Journal Citation Report were invited to complete an online survey about the statistical and design problems they most frequently found in manuscripts. Content analysis of the responses identified major issues. Editors and statistical reviewers (n = 25 from 20 journals responded. Respondents described problems that we classified into two, broad themes: A. statistical and sampling issues and B. inadequate reporting clarity or completeness. Problems included in the first theme were (1 inappropriate or incomplete analysis, including violations of model assumptions and analysis errors, (2 uninformed use of propensity scores, (3 failing to account for clustering in data analysis, (4 improperly addressing missing data, and (5 power/sample size concerns. Issues subsumed under the second theme were (1 Inadequate description of the methods and analysis and (2 Misstatement of results, including undue emphasis on p-values and incorrect inferences and interpretations. Conclusions The scientific quality of submitted manuscripts would increase if researchers addressed these common design, analytical, and reporting issues. Improving the application and presentation of quantitative methods in scholarly manuscripts is essential to advancing medical research.

    The main aim of this paper is to discuss the problem concerning the analyticity of the solutions of analytic non-linear elliptic boundary value problems.It is proved that if the corresponding first variation is regular in Lopatinski(i) sense,then the solution is analytic up to the boundary.The method of proof really covers the case that the corresponding first variation is regularly elliptic in the sense of Douglis-Nirenberg-Volevich,and hence completely generalize the previous result of C.B.Morrey.The author also discusses linear elliptic boundary value problems for systems of ellip tic partial differential equations where the boundary operators are allowed to have singular integral operators as their coefficients.Combining the standard Fourier transform technique with analytic continuation argument,the author constructs the Poisson and Green's kernel matrices related to the problems discussed and hence obtain some representation formulae to the solutions.Some a priori estimates of Schauder type and Lp type are obtained.

    The authors describe the historical evolution and present status of affirmative action in medical school admission policies. The demographic transformation of the medical student body between 1965 and 1998 from a homogeneous white and male group to one that includes a significant number of women and minority students is presented. Challenges to affirmative action are outlined. In addition, the authors note the increasing diversity of the general population and discuss the benefits of diversity to medical practice, research, and education. However, the upper ranks of professors and administrators remain white and male. The rationale for an innovative course on the history of bias in medicine and the benefits that diversity brings to the medical enterprise are presented.

    The objective of this study was to examine the records of pediatric dental patients treated under general anesthesia to determine if there had been any significant change in preoperative diagnoses between 1990-99 and 2000-08. The records of 3298 pediatric dental patients treated in the operating room under general anesthesia at the University of North Carolina (UNC) Children's Hospital were examined and medical diagnoses recorded. The number of cases treated by calendar year was obtained. The results of this study did not find any significant differences in percentage frequency of medical diagnoses between the years of 1990-99 and 2000-08. There has been a steady increase in the number of cases treated under general anesthesia over the period of the study. 1. Dental care under general anesthesia remains an important treatment option. 2. The medical diagnoses of children provided dental treatment under general anesthesia has not changed significantly over the past nineteen years at the UNC Children's Hospital. 3. The demand to provide dental care for children under general anesthesia has continued to increase.

    Full Text Available Introduction: We operationalized the taxonomy developed by Hauer and colleagues describing common clinical performance problems. Faculty raters pilot tested the resulting worksheet by observing recordings of problematic simulated clinical encounters involving third-year medical students. This approach provided a framework for structured feedback to guide learner improvement and curricular enhancement. Methods: Eighty-two problematic clinical encounters from M3 students who failed their clinical competency examination were independently rated by paired clinical faculty members to identify common problems related to the medical interview, physical examination, and professionalism. Results: Eleven out of 26 target performance problems were present in 25% or more encounters. Overall, 37% had unsatisfactory medical interviews, with ‘inadequate history to rule out other diagnoses’ most prevalent (60%. Seventy percent failed because of physical examination deficiencies, with missing elements (69% and inadequate data gathering (69% most common. One-third of the students did not introduce themselves to their patients. Among students failing based on standardized patient (SP ratings, 93% also failed to demonstrate competency based on the faculty ratings. Conclusions: Our review form allowed clinical faculty to validate pass/fail decisions based on standardized patient ratings. Detailed information about performance problems contributes to learner feedback and curricular enhancement to guide remediation planning and faculty development.

    Full Text Available In the recent decades, periodontal disease has been identified as a risk factor for pre-term deliveries. Hence, it is important to evaluate the awareness of health-care providers of the association between periodontal diseases and pre-term birth. A self-administered questionnaire was distributed to random samples representing general medical practitioners (GMPs, general dental practitioners (GDPs and Gynecologists for this study. A knowledge score was calculated for correct answers to 11 survey questions related to oral health effects during pregnancy and compared among the three groups. In this study, 133 physicians, 135 dentists and 100 Gynecologists completed the questionnaire. More GDPs (67.4% than GMPs (56.4% and Gynecologists (63% reported there was an association between periodontal disease and pre-term low birth weight. Efforts to increase this awareness may prove valuable in improving preventive care during pregnancy.

  3. Interior-point algorithm based on general kernel function for monotone linear complementarity problem

    2009-01-01

    A polynomial interior-point algorithm is presented for monotone linear complementarity problem (MLCP) based on:a class of kernel functions with the general barrier term, which are called general kernel functions. Under the mild conditions for the barrier term, the complexity bound of algorithm in terms of such kernel function and its derivatives is obtained. The approach is actually an extension of the existing work which only used the specific kernel functions for the MLCP.

  4. Principle of reciprocity solves the most important problems in bioimpedance and in general in bioelectromagnetism

    Though the principle of reciprocity was invented by Hermann von Helmholtz already over 150 years ago, and though it is a very powerful tool in solving various important problems in bioelectromagnetism, it is not generally used. In impedance tomography the measurement sensitivity distribution has generally been misunderstood. This can be easily demonstrated with the principle of reciprocity. Some other applications of the principle of reciprocity are also discussed.

    In this paper we analyze the error behavior of general linear methods applied to some classes of one-parameter multiply stiff singularly perturbed problems. We obtain the global error estimate of algebraically and diagonally stable general linear methods. The main result of this paper can be viewed as an extension of that obtained by Xiao [13] for the case of Runge-Kutta methods.

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The transport behavior of free boundary value problems for a class of generalized diffusion equations was studied. Suitable similarity transformations were used to convert the problems into a class of singular nonlinear two-point boundary value problems and similarity solutions were numerical presented for different representations of heat conduction function, convection function, heat flux function, and power law parameters by utilizing the shooting technique. The results revealed the flux transfer mechanism and the character as well as the effects of parameters on the solutions.

    Physicians have difficulties to access and analyse information in a medical record. In a previous work on drug databanks, we have shown that with an iconic language as VCM, an icon-based presentation can help physicians to access medical information. Our objective, herein, is to study whether VCM can be used in an electronic medical record for facilitating physician access in general practice. We identify the data and the functionalities of an electronic medical record that could benefit from VCM icons representing clinical findings, patient history, etc. We also present a preliminary evaluation of this new icon-focused interface. We conclude by discussing the results like the assessment of the user's satisfaction and pointing out the importance of coding data.

  8. The adequacy of education for general practice: a medical educator's viewpoint.

    Science.gov (United States)

    STEWART, C B

    1963-04-06

    The effect on medical education of the doubling of medical knowledge every 10 years is discussed. A brilliant student who might successfully master all the present facts and theories by graduation would be seriously out of date 10 years later, and hopelessly so by retirement age unless he continued his education while in practice. Lengthening the undergraduate course is not considered an effective solution, nor is increasing the general practice internship to two years. Emphasis should be placed on self-education by the medical student, on the inculcation of habits of study and motivation to encourage lifelong learning, and on the provision of more adequate programs of continuing education for the practising doctor. Teachers in medical schools require a better understanding of and interest in the learning processes of their students rather than concentrating on the exposition of their own knowledge.

    Diabetes mellitus, although a chronic disease, also can cause acute, sudden symptoms requiring emergency intervention. In these cases, Emergency Medical Dispatchers (EMDs) must identify true diabetic complaints in order to determine the correct care. In 911 systems utilizing the Medical Priority Dispatch System (MPDS), International Academies of Emergency Dispatch-certified EMDs determine a patient's chief complaint by matching the caller's response to an initial pre-scripted question to one of 37 possible chief complaints protocols. The ability of EMDs to identify true diabetic-triggered events reported through 911 has not been studied. The primary objective of this study was to determine the percentage of EMD-recorded patient cases (using the Diabetic Problems protocol in the MPDS) that were confirmed by either attending paramedics or the hospital as experiencing a diabetic-triggered event. This was a retrospective study involving six hospitals, one fire department, and one ambulance service in Salt Lake City, Utah USA. Dispatch data for one year recorded under the Diabetic Problems protocol, along with the associated paramedic and hospital outcome data, were reviewed/analyzed. The outcome measures were: the percentage of cases that had diabetic history, percentage of EMD-identified diabetic problems cases that were confirmed by Emergency Medical Services (EMS) and/or hospital records as true diabetic-triggered events, and percentage of EMD-identified diabetic patients who also had other medical conditions. A diabetic-triggered event was defined as one in which the patient's emergency was directly caused by diabetes or its medical management. Descriptive statistics were used for categorical measures and parametric statistical methods assessed the differences between study groups, for continuous measures. Three-hundred ninety-three patient cases were assigned to the Diabetic Problems Chief Complaint protocol. Of the 367 (93.4%) patients who had a documented

  10. Examining the Accuracy of Astrophysical Disk Simulations with a Generalized Hydrodynamical Test Problem

    Science.gov (United States)

    Raskin, Cody; Owen, J. Michael

    2016-11-01

    We discuss a generalization of the classic Keplerian disk test problem allowing for both pressure and rotational support, as a method of testing astrophysical codes incorporating both gravitation and hydrodynamics. We argue for the inclusion of pressure in rotating disk simulations on the grounds that realistic, astrophysical disks exhibit non-negligible pressure support. We then apply this test problem to examine the performance of various smoothed particle hydrodynamics (SPH) methods incorporating a number of improvements proposed over the years to address problems noted in modeling the classical gravitation-only Keplerian disk. We also apply this test to a newly developed extension of SPH based on reproducing kernels called CRKSPH. Counterintuitively, we find that pressure support worsens the performance of traditional SPH on this problem, causing unphysical collapse away from the steady-state disk solution even more rapidly than the purely gravitational problem, whereas CRKSPH greatly reduces this error.

    2016-01-01

    Full Text Available The diversity of medical factors makes the analysis and judgment of uncertainty one of the challenges of medical diagnosis. A well-designed classification and judgment system for medical uncertainty can increase the rate of correct medical diagnosis. In this paper, a new multidimensional classifier is proposed by using an intelligent algorithm, which is the general fuzzy cerebellar model neural network (GFCMNN. To obtain more information about uncertainty, an intuitionistic fuzzy linguistic term is employed to describe medical features. The solution of classification is obtained by a similarity measurement. The advantages of the novel classifier proposed here are drawn out by comparing the same medical example under the methods of intuitionistic fuzzy sets (IFSs and intuitionistic fuzzy cross-entropy (IFCE with different score functions. Cross verification experiments are also taken to further test the classification ability of the GFCMNN multidimensional classifier. All of these experimental results show the effectiveness of the proposed GFCMNN multidimensional classifier and point out that it can assist in supporting for correct medical diagnoses associated with multiple categories.

The cognitive domains examined were general cognitive ability and executive abilities.Methods: Three different clinical samples of pupils with school problems were analyzed to assess their cognitive Wechsler Intelligence Scale for Children profiles. In particular, the general cognitive ability index and the executive markers (ie, verbal memory index and processing speed index were of interest. Of the total sample (n = 198, two main groups were contrasted; one met the full criteria for attention deficit hyperactivity disorder (ADHD/subthreshold ADHD, and one was comprised of those with milder attention problems, insufficient to meet the criteria for ADHD/subthreshold ADHD.Results: It could be demonstrated that both groups had a significantly higher score on the general cognitive ability index than on measures of working memory and processing speed. This difference was more pronounced for boys.Conclusion: These types of cognitive differences need to be considered in children with different kinds of learning, behavior, and attention problems; this is also true for children presenting with an average general intelligence quotient and with milder attention problems. Current educational expectations are demanding for children with mild difficulties, and such cognitive information will add to the understanding of the child's learning problems, hopefully leading to a better adapted education than that conventionally available.Keywords: working memory, processing speed, children, learning and

    Full Text Available The prevailing undergraduate medical training process still favors disconnection and professional distancing from social needs. The Brazilian Ministries of Education and Health, through the National Curriculum Guidelines, the Incentives Program for Changes in the Medical Curriculum (PROMED, and the National Program for Reorientation of Professional Training in Health (PRO-SAÚDE, promoted the stimulus for an effective connection between medical institutions and the Unified National Health System (SUS. In accordance to the new paradigm for medical training, the Centro Universitário Serra dos Órgãos (UNIFESO established a teaching plan in 2005 using active methodologies, specifically problem-based learning (PBL. Research was conducted through semi-structured interviews with third-year undergraduate students at the UNIFESO Medical School. The results were categorized as proposed by Bardin's thematic analysis, with the purpose of verifying the students' impressions of the new curriculum. Active methodologies proved to be well-accepted by students, who defined them as exciting and inclusive of theory and practice in medical education.

    In Germany, there is a shortage of young physicians in several specialties, the situation of general practitioners (GP) being especially precarious. The factors influencing the career choice of German medical students are poorly understood. This study aims to identify factors influencing medical students' specialty choice laying a special focus on general practice. The study was designed as a cross-sectional survey. In 2010, students at the five medical schools in the federal state of Baden-Wuerttemberg (Germany) filled out an online-questionnaire. On 27 items with 5-point Likert scales, the students rated the importance of specified individual and occupational aspects. Furthermore, students were asked to assign their intended medical specialty. 1,299 students participated in the survey. Thereof, 1,114 students stated a current choice for a specialty, with 708 students choosing a career in one of the following 6 specialties: internal medicine, surgery, gynaecology and obstetrics, paediatrics, anaesthetics and general practice. Overall, individual aspects ('Personal ambition', 'Future perspective', 'Work-life balance') were rated as more important than occupational aspects (i.e. 'Variety in job', 'Job-related ambition') for career choice. For students favouring a career as a GP individual aspects and the factor 'Patient orientation' among the occupational aspects were significantly more important and 'Job-related ambition' less important compared to students with other specialty choices. This study confirms that future GPs differ from students intending to choose other specialties particularly in terms of patient-orientation and individual aspects such as personal ambition, future perspective and work-life balance. Improving job-conditions in terms of family compatibility and work-life balance could help to increase the attractiveness of general practice. Due to the shortage of GPs those factors should be made explicit at an early stage at medical school to increase

    Highlights: ► Radiologists published only 0.2% of articles in five general medical journals. ► Most original articles from radiologists were funded and were prospective studies. ► Radiology researchers from only 11 countries published at least one original article. -- Abstract: Objective: To evaluate scientific papers published by radiologists in high impact general medical journals between 1996 and 2010. Methods: A MEDLINE search was performed in five high impact general medical journals (AIM, BMJ, JAMA, Lancet, and NEJM) for all articles of which a radiologist was the first author between 1996 and 2010. The following information was abstracted from the original articles: radiological subspecialty, imaging technique used, type of research, sample size, study design, statistical analysis, study outcome, declared funding, number of authors, collaboration, and country of the first author. Results: Of 216 (0.19%) articles were published by radiologists in five general medical journals between 1996 and 2010, 83 were original articles. Fifteen (18.1%) original articles were concerned with the field of vascular/interventional radiology, 24 (28.9%) used combined imaging techniques, 76 (91.6%) were clinical research, 63 (75.9%) had a sample size of >50, 65 (78.3%) were prospective, 78 (94.0%) performed statistical analysis, 83 (100%) showed positive study outcomes, 57 (68.7%) were funded, 49 (59.0%) had from four to seven authors, and 79 (95.2%) were collaborative studies. Conclusions: A very small number (0.19%) in five high impact general medical journals was published by radiologists between 1996 and 2010.

Overall, individual aspects ('Personal ambition', 'Future perspective', 'Work-life balance' were rated as more important than occupational aspects (i.e. 'Variety in job', 'Job-related ambition' for career choice. For students favouring a career as a GP individual aspects and the factor 'Patient orientation' among the occupational aspects were significantly more important and 'Job-related ambition' less important compared to students with other specialty choices. Conclusions This study confirms that future GPs differ from students intending to choose other specialties particularly in terms of patient-orientation and individual aspects such as personal ambition, future perspective and work-life balance. Improving job-conditions in terms of family compatibility and work-life balance could help to increase the attractiveness of general practice. Due to the shortage of GPs those factors should

    Medical students experience higher prevalence of mental illness than age-matched controls and are less likely to access appropriate help when this happens. The aim of this study was to determine the range of strategies deployed by medical schools to support medical students with mental health concerns and to use this to identify distinct categories. Websites and documents relating to all 32 UK medical schools were looked at, as were reports for quality assurance visits carried out by the General Medical Council (UK). A structured telephone interview was carried out with medical schools. Support services were examined by tracing the path that might be taken by a hypothetical student with mental health concerns of varying severity, seeing what was required and what was available at each stage. A range of support strategies is available to most medical students both from their medical school and from generic services in the university. Medical students will usually first contact a personal tutor or a senior member of faculty or be contacted by them as a result of concerns raised either via performance issues or by another student. While individual support interventions are mostly based on evidence of effectiveness, there is no unifying theory in terms of what constitutes effective support. To enable analysis of support interventions and comparison across providers, a six-stage conceptual model of prevention was developed. The six stages are the following: prevention, identification, referral, escalation, treatment, and reintegration. The staged model, derived from analysis of existing interventions, provides a framework for evaluation of current provision and comparison of different methods of delivery. Moreover, it provides a framework for future research.

The objective of this study is to determine whether a theme-based ultrasound teaching session, dedicated to the use of ultrasound in the management of the hypotensive patient, can impact medical students’ ultrasound education and provide critical problem-solving exercises.Methods: This was a cross-sectional study using an innovative approach to train 3rd year medical students during a 1-day ultrasound training session. The students received a 1-hour didactic session on basic ultrasound physics and knobology and were also provided with YouTube hyperlinks, and links to smart phone educational applications, which demonstrated a variety of bedside ultrasound techniques. In small group sessions, students learned how to evaluate patients for pathology associated with hypotension. A knowledge assessment questionnaire was administered at the end of the session and again 3 months later. Student knowledge was also assessed using different clinical scenarios with multiple-choice questions.Results: One hundred and three 3rd year medical students participated in this study. Appropriate type of ultrasound was selected and accurate diagnosis was made in different hypotension clinical scenarios: pulmonary embolism, 81% (95% CI, 73%–89%; abdominal aortic aneurysm, 100%; and pneumothorax, 89% (95% CI, 82%–95%. The average confidence level in performing ultrasound-guided central line placement was 7/10, focused assessment with sonography for trauma was 8/10, inferior vena cava assessment was 8/10, evaluation for abdominal aortic aneurysm was 8/10, assessment for

    In North America, where it was born, problem-based learning (PBL) has seen dips and rises in its popularity, but its inherent strengths have led to its spread to medical schools all over the world. Although its use at medical schools in some Western countries has already been examined, no one has looked at its status in many other countries, including China. The aim of this study is to determine the number of schools currently using PBL in China, the degree to which they use it, and the reasoning behind such usage. We used survey and internet search to examine PBL usage at Chinese medical schools. We were able to collect data from 43 first-class Chinese medical schools that are geographically diverse and thus representative of medical schools all across China. 34 (79.1%) of the 43 medical schools use PBL in the preclinical curriculum. Of the 34, data were collected from 24 (70.6%) medical schools regarding the extent of their PBL usage. Nine (37.5%) schools use PBL for less than 10% of preclinical hours, 14 (58.3%) schools use PBL for 10-50% of preclinical hours, and one (4.2%) school uses PBL for more than 50% of preclinical hours. In our sample of Chinese medical institutions, a large majority of schools use PBL, however, most schools use it for less than 50% of total preclinical curricular hours. Our results suggest that schools are interested in increasing the number of curricular hours devoted to PBL but are constrained by resources.

    Full Text Available Abstract Background In order to get sickness benefit a sick-listed person need a medical certificate issued by a physician; in Sweden after one week of self-certification. Physicians experience sick-listing tasks as problematic and conflicts may arise when patients regard themselves unable to work due to complaints that are hard to objectively verify for the physician. Most GPs and orthopaedic surgeons (OS deal regularly with sick-listing issues in their daily practice. The aim of this study was to explore perceived problems and coping strategies related to tasks of sickness certification among general practitioners (GP and orthopaedic surgeons (OS. Methods A cross-sectional study about sickness certification in two Swedish counties, with 673 participating GPs and 149 OSs, who answered a comprehensive questionnaire. Frequencies together with crude and adjusted (gender and working years Odds ratios were calculated. Results A majority of the GPs and OSs experienced problems in sickness certification every week. To assess the patient's work ability, to handle situations when they and the patient had different opinions about the need for sickness absence, and to issue prolongation certificates when the previous was issued by another physician were reported as problematic by a majority in both groups. Both GPs and OSs prolonged sickness certifications due to waiting times in health care or at Social Insurance Office (SIO. To handle experienced problems they used different strategies; OSs issued sickness certificates without personal appointment more often than the GPs, who on the other hand reported having contact with SIO more often than the OSs. A higher rate of GPs experienced support from management and had a common strategy for handling sickness certification at the clinic than the OSs. Conclusion Most GPs and OSs handled sickness certification weekly and reported a variety of problems in relation to this task, generally GPs to a higher extent
