Cardiovascular Risk and Its Associated Factors in Health Care Workers in Colombia: A Study Protocol.

Background: Cardiovascular diseases are the leading cause of mortality worldwide, for this reason, they are a public health problem. In Colombia, cardiovascular diseases are the main cause of mortality, having a death rate of 152 deaths per 100,000 population. There are 80% of these cardiovascular events that are considered avoidable. Objective: The objective of the study is to determine the prevalence of the cardiovascular risk and its associated factors among the institution’s workers in order to design and implement interventions in the work environment which may achieve a decrease in such risk. Methods: An analytical cross-sectional study was designed to determine the cardiovascular risk and its associated factors among workers of a high complexity health care institution. A self-applied survey will be conducted considering sociodemographic aspects, physical activity, diet, alcohol consumption, smoking, level of perceived stress, and personal and family history. In a second appointment, a physical examination will be made, as well as anthropometric measurements and blood pressure determination. Also, blood samples for evaluating total and high density lipoprotein cholesterol, triglycerides, and fasting blood sugar will be taken. A ten-year global risk for cardiovascular disease will be determined using the Framingham score. A descriptive analysis of the population’s characteristics and a stratified analysis by sex, age, and occupation will be made. Bivariate and multivariate analysis will be made using logistic regression models to evaluate the association between cardiovascular risk and the independent variables. The research protocol was approved by the Scientific and Technical Committee and the Ethics Committee on Research of the Fundacion Cardiovascular de Colombia. Results: The protocol has already received funding and the enrollment phase will begin in the coming months. Conclusions: The results of this study will give the foundation for the design, implementation, and evaluation of a program based on promoting healthy lifestyles, such as performing regular physical activity and healthy food intake in order to avoid and/or control the cardiovascular risk in the workers of a high complexity health care institution.

Estudio multicéntrico español SHECTS: situación hepática de los pacientes con hepatitis crónica por el VHC en tratamiento sustitutivo renal con hemodiálisis

La hepatitis C cronica en pacientes en dialisis es mayor que en la poblacion general. El estudio SHECTS tie- ne como objetivos analizar el nivel de estudio y seguimien- to de los pacientes con infeccion cronica por el virus de la hepatitis C (VHC) en hemodialisis y determinar su prevalen- cia actual. Metodo: Estudio de cohorte multicentrico na- cional, realizado entre septiembre de 2010 y septiembre de 2011. Se envio un cuaderno de recogida de datos a todas las unidades de hemodialisis de Espana para incluir informacion de la unidad y de la situacion nefrologica y hepatologica de sus pacientes VHC-positivos. Resultados: Participaron en el estudio 187 unidades de hemodialisis (71 hospitalarias). La prevalencia del VHC se estimo en el 5,6 %. La causa mas fre- cuente de enfermedad renal cronica fue la glomerular (25 %); del 72,1% de los pacientes que se habia sometido a una biopsia renal, el 23,2 % presentaba una glomerulonefritis que podia estar asociada al VHC. No se disponia del genoti- po en el 64 %, ecografia hepatica en el 61,3 %, biopsia hepatica en el 87,7 %. Un tercio era seguido por un digesto- logo. El 26,6 % habia recibido tratamiento antiviral, con res- puesta viral sostenida en el 35,3 % y suspension del trata- miento en el 67,4 %. Conclusion: La prevalencia del VHC en hemodialisis en Espana ha disminuido notablemente en la ultima decada hasta igualarse a la de paises del entorno. Es- tos pacientes tienen un estudio incompleto de su hepatopa- tia y los tributarios de tratamiento antiviral y no tratados constituyen un numero considerable, a pesar de tener car- gas virales bajas y ser candidatos a trasplante renal.
Breast Metastatic Localization of Signet-Ring Cell Gastric Carcinoma

Metastatic tumors in the breast are quite rare and constitute 0,5 to 6% of all breast malignancies. They often occur in a polymetastatic context. Gastrointestinal lesions rarely metastasize to the breast. The first case of a metastasis deposit to the breast and ovary from gastric signet-ring cell carcinoma was reported in the literature in 1999. Since this report, only 5 cases have been reported. We present a case report of a 37-year-old woman who complained of a lump in the left breast. Two months earlier, the woman underwent a subtotal gastrectomy and a total hysterectomy with double anexectomy, which histologically was diagnosed of gastric signet-ring carcinoma, disseminated with Krukenberg's tumor. In those days, the patient was following a chemotherapy treatment. A core needle biopsy of the lesion in left breast revealed cells with signet-ring features, with probably gastric origin.
Curricular Innovations for Medical Students in Palliative and End-of-Life Care: A Systematic Review and Assessment of Study Quality

Abstract Background: Recent focus on palliative and end-of-life care has led medical schools worldwide to enhance their palliative care curricula. Objective: The objective of the study was to describe recent curricular innovations in palliative care for medical students, evaluate the quality of studies in the field, and inform future research and curricular design. Methods: The authors searched Medline, Scopus, and Educational Resource Information Center (ERIC) for English-language articles published between 2007 and 2013 describing a palliative care curriculum for medical students. Characteristics of the curricula were extracted, and methodological quality was assessed using the Medical Education Research Study Quality Instrument (MERSQI). Results: The sample described 48 curricula in 12 countries. Faculty were usually interdisciplinary. Palliative care topics included patient assessment, communication, pain and symptom management, psychosocial and spiritual needs, bioethics and the law, role in the heal.
Empirical Antibiotics Use in Soft Tissue Infections

Purpose Various antibiotics are available to treat soft-tissue infections. However, it is unclear if the empirical antibiotic is always appropriate or the most economical. Objective To determine the percentage of empirically treated wounds susceptible to the antibiotic therapy prescribed, and to determine the percentage of wounds treated with the most economical antibiotic therapy. Methods A retrospective chart review was performed on all charts with a diagnosis of ‘soft-tissue infection’ between January 1, 2005, and June 30, 2005, at St Joseph's Hospital, Hamilton, Ontario. Eligible charts were identified using the medical diagnosis coding system. The following diagnoses (including subheadings) were included: cellulitis, lymphangitis, abscess, carbuncle or furuncle. The following was extracted: patient demographics; soft-tissue diagnosis; name, dose and duration of antibiotics used; culture results; and Gram-stain results. A comparison between the empirical antibiotic prescribed and the microbiology result was made. An assessment was performed on the cost of the initial empirical antibiotic treatment compared with less-expensive effective alternatives. Results For soft-tissue infections with positive culture growth, empirical antibiotic treatment was appropriate in all abscess cases, 50% of ulcer cases and 83% of cellulitis cases. for cellulitis patients receiving a single empirical antibiotic, it was appropriate in 89% of cases. Only 42% of culture-positive patients were treated with the most economical regimen, multiple antibiotics being the most common fault. Conclusions To be most economical, a single empirical antibiotic should be used to treat cellulitis. Culture results should be used to guide any antibiotic changes.
Application of Pi-cells in time-multiplexed stereoscopic and autostereoscopic displays based on LCD panels

We investigated Pi-cell based polarization switches regarding their applications in both glass type and autostereoscopic 3D displays, which employ LCD as an image panel. It is found that Pi-cell should be divided into the number of individually addressable segments to be capable of switching in synchronism with line-by-line image update in order to reduce time-mismatch crosstalk. We estimated the number of segments, sufficient to reduce local and average crosstalk to acceptable level. It is found experimentally that the displayed stereoscopic image has unequal brightness and crosstalk in the right and left channels. The asymmetry of stereoscopic image parameters is probably caused by the asymmetry of rise/fall time, inherent in Pi-cells. The improved driving method capable of symmetrizing the crosstalk and brightness is proposed. It is also shown that the response time acceleration technique (RTA), developed for the reduction of motion blur, is capable of canceling the dynamic crosstalk caused by slow response of LCD pixels.
THE IDEA OF ONE WAY WORD FORMATION DICTIONARY

In the modern word formative theory of neologisms there is practically no description of concrete unusual occasional way of word formation, such as holophrasis, gendiadis, decomposition and others. There is also no dictionary, describing one of these types of word composition. There are two specific questions, which occur with the process of с reation of one way word formation (holophrase) dictionary: 1) how to introduce the holophrastic construction (HC) into the dictionary; 2) the context of usage of HC. Though HC is polycomponental, the introduction should be only one – by the first word in the construction. The context of usage of HC is usually limited by the sentence, in which HC is used. The HC dictionary emphasizes the new opening in the philosophic understanding of the sense of meaning and its connection with the lexicographic semantisation.
Serological evidence of ongoing transmission of dengue virus in permanent residents of Key West, Florida.

INTRODUCTION Dengue fever is the most important mosquito-borne viral disease in the world, with 40% of the global population at risk of infection. Dengue virus is responsible for infections in over 100 countries, including the Americas and Caribbean Basin; however, it has been largely eradicated from the United States through the implementation of effective vector control programs. However, between 2009 and 2010, 27 permanent residents of Key West, Florida, were reported to have locally acquired infections, marking the first autochthonous cases detected in Florida since 1934. Despite this recent and unusual transmission, and the potential risk of serious illness associated with sequential infections, no active surveillance had been conducted since. MATERIALS AND METHODS A serosurvey of permanent residents of Key West, Florida, was conducted in March of 2012. After informed consent, enrolled participants (n=173) were given a dengue virus rapid diagnostic test and completed a corresponding questionnaire. RESULTS The presence of immunoglobulin G (IgG) antibodies was indicated in 12 participants (6.9%), all of whom reported travel to endemic countries within the past 2 years. Surprisingly, six participants (3.5%) without any recent travel outside the state of Florida gave positive results for IgM antibodies. The presence of birdbaths and bromeliads on the property and sleeping outdoors emerged as significant factors related to previous exposure, whereas home air conditioning without the use of open windows and the use of mosquito repellent were protective. CONCLUSIONS These findings suggest local transmission occurred in Key West in early 2012, indicating that transmission may not have subsided in 2010.
A Review on Reversible Logic Gates and its QCA Implementation

Quantum Dot Cellular Automata (QCA) is a rising innovation which seems to be a good competitor for the next generation of digital systems and widely utilized as a part of advanced frameworks. It is an appealing substitute to ordinary CMOS innovation because of diminutive size, faster speed, extremely scalable feature, ultralow power consumption and better switching frequency. The realization of quantum computation is not possible without reversible logic. Reversible logic has enlarged operations in quantum computation. Generally reversible computing is executed when system composes of reversible gates. It has numerous fields of use as applied science, quantum dot cellular automata as well as low power VLSI circuits, low power CMOS, digital signal processing, computer graphics. In this paper, the quantum implementation of primitive reversible gate has been presented. The proposed gates have been designed and simulated using QCADesigner.

Adaptation improvement using fuzzy logic

A module of a Student Model in a Virtual Learning Environment will be presented in order to promote the personalization of instructional material based on the dynamic knowledge levels and learning styles. The improvement is provided by the inclusion experts' experience in the teaching field whose opinions have been expressed in fuzzy rules using two input linguistic variables (knowledge level and learning style) and two linguistic output variables (difficulty level and individual/group work). These last two variables categorize instructional materials.
Methodology for designing cryptographic systems with advanced functionality based on a modular approach

−92− Synthesiology English edition Vol.7 No.2 pp.92-104 (Sep. 2014) on average 34 pages long of which on average 24 pages were devoted to security definitions and security proofs. The contents are lists of difficult-to-understand mathematical formulas, and it is not easy to understand the correlation between these formulas and actual security. This is thought to be the major barrier in introducing highly functional cryptographic schemes to the real world. Particularly, even specialized researchers find it difficult to be convinced of the security, and a general user cannot be expected to use these schemes with full confidence. In fact, error in proof is often discovered later, even with cryptographic schemes that the designers have claimed that their security has been mathematically proven. Hereinafter, this problem will be called the security verification problem in cryptographic schemes.
LVQ base models for recognition of human faces

The important task in the design of a combined classifier is to select the suitable base models, which constitute its building blocks. The main contribution of this research work is an attempt to solve the problem of adaptively selecting the base learning vector quantisation (LVQ) models for recognition of human faces. A novel approach is presented for the automatic elimination of redundant hidden layer neurons of base models. Redundancy of a neuron is measured by the variance of the face image represented by that neuron of the neural network. Empirical comparison is performed between growing and pruning networks, i.e. networks generated through elimination of redundant or blind neurons. Results indicate that the elimination of blind neurons leads to base models which have less structural complexity and are more efficient than those generated using growing network.
A POLÍTICA NACIONAL DE ATENÇÃO ONCOLÓGICA E O PAPEL DA ATENÇÃO BÁSICA NA PREVENÇÃO E CONTROLE DO CÂNCER

This paper concerns cancer as a public health problem in Brazil and introduces the Brazilian Cancer Control Policy as a strategy to integrate actions or programs for cancer control. Among these activities are the control of cervical and breast cancer, considered national priorities due to their high incidence and the possibility of morbidity and mortality reduction by screening of the population. The Division of Cancer Care of the National Cancer Institute’s Cancer Prevention and Surveillance Coordination, has been working with States Secretaries of Health to help with the organization of the network of oncological services of the States. Based on this experience, this paper’s goal is to offer a panoramic view of the current cancer control initiatives and highlights the role of primary care in the early detection of cervical and breast cancer in Brazil. Finally, the need is stressed for an effective enlistment of a variety of players in the social production of health and competency building of the healthcare network so that the strategies of cancer control take root and produce results.
Metabolic syndrome among urban Indian young adults: prevalence and associated risk factors.

BACKGROUND We estimated the prevalence of metabolic syndrome among urban Indian young adults (18-25 years) as defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), Internation Diabetes Federation (IDF), and Indian consensus statement criteria. METHOD We included 473 urban young adults through simple random sampling methodology to estimate the prevalence and associated risk factors for metabolic syndrome. RESULTS Prevalence of metabolic syndrome was estimated to be 3.6 [95% confidence interval (CI) 2.2-5.8], 6.6% (95% CI 4.6-9.1), and 8.7% (95% CI 6.4-11.6) using the NCEP ATP III, IDF, and Indian consensus statement criteria, respectively. Men had significantly higher waist circumference, systolic blood pressure, fasting blood glucose, and triglycerides, whereas mean concentrations of both high-density lipoprotein cholesterol (HDL-C) and total cholesterol were significantly higher among women. Low HDL-C (38.9%), high blood pressure (26%), and central obesity (16.1%) were the most common component risk factors. Although less than 4% of normal weight adults met the criteria for metabolic syndrome, rates increased in overweight individuals and reached a prevalence of 87% in the obese participants. In all, 61.3% of the total population had one or more risk factors for metabolic syndrome. CONCLUSION The prevalence of metabolic syndrome is high among urban young adults in India, and it increased with increase in body mass index (BMI). Each component risk factor in isolated form-increased BMI, smoking, and history of hypertension--is an associated risk factor for metabolic syndrome. Although it is unclear whether metabolic syndrome screening in young Indians as a means to prevent adverse cardiovascular health outcomes is appropriate, healthy lifestyles should nevertheless be encouraged, and young adults should be considered as an important group for cardiovascular risk reduction programs.
IaaS clouds vs. clusters for HPC: a performance study

The increasing amount of data collected in the fields of physics and bio-informatics allows researchers to build realistic, and therefore accurate, models/simulations and gain a deeper understanding of complex systems. This analysis is often at the cost of greatly increased processing requirements. Cloud computing, which provides on demand resources, can offset increased analysis requirements. While beneficial to researchers, adaption of clouds has been slow due to network and performance uncertainties. We compare the performance of cloud computers to clusters to make clear the advantages and limitations of clouds. Focus has been put on understanding how virtualization and the underlying network effects performance of High Performance Computing (HPC) applications. Collected results indicate that performance comparable to high performance clusters is achievable on cloud computers depending on the type of application run.
Evaluation of Pre-Assessment Method on Improving Students Performance in Complex Analysis Course

Engineering mathematics has always been the fundamental and important courses in engineering curriculum. Engineering students are required to understand the fundamental of mathematics and apply this knowledge to solve real world problem. The requirement for engineering mathematics for the different branches of engineering is more or less the same at the first and second year level but tend to be more specific and complicated at the later years. Problem started to occur when students lack the fundamental knowledge of mathematics and unable to grasp the higher level of mathematics. One such course is Complex Analysis, which is one of the compulsory course for the third year electrical engineering students at the University Kebangsaan Malaysia, UKM. The course requires the students to be able to understand, analyse and apply the complex concepts and techniques in solving practical electrical engineering problem. However, previous results for different batch of students revealed that most students taking the course had fundamental problem in understanding the new concept although such concepts were built upon on the fundamental mathematics learned in the first year. Thus the objective of this study is to improve student’s performance by assessing systematically student’s level of understanding on a particular topic in the complex analysis course using the Rasch measurement technique. Students were given pre-midsem test with the combination of different question related to the learning outcomes of the course. The result of the pre-midsem test were then analysed using the Rasch measurement and the correlation level between the performance of each student and question was identified.Rasch measurement was able evaluate the validity of the intended question given and classifying the students according to their level of understanding on the course. Preliminary findings indicated that majority of the students have problems with contour integral especially the use of the Cauchy-Goursat theorem in solving application problem. With this early identification, the existing method of teaching on the particular topics needs to be adjusted and re-evaluated. From this study, some suggestions were put toward for future improvement in the teaching and learning of the Complex Analysis course.
A meta-analysis of the effectiveness of online distance education compared to face-to-face education

Much of the research on educational technologies has shown that there is no significant difference in the effectiveness of learning with regards to broad notions of distance education compared with face-to-face education. Still, two issues of continuing debate are the identification of factors that have influenced these findings and methodological design flaws of experimental studies. In order to examine these two issues with regards to the effectiveness of online distance education (ODE) between 1995 and 2003,1 conducted a meta-analysis of existing research. This statistical approach synthesized 23 studies from published literature and electronic data bases. This quantitative analysis provided the effect sizes for three outcome variables that measured student achievement, student satisfaction, and student dropout rates. In this research, I asked the following questions: (A) Is there a difference between the effectiveness of ODE and face-to-face (F2FE)? This question had three sub-questions: (i) Is there a difference in student achievement measured by final test scores between ODE and F2FE? (ii) Is there a difference in student satisfaction between ODE and F2FE? (iii) Is there a difference in student dropout rates between ODE and F2FE? (B) Does media influence the effectiveness of ODE? (C) Is there any evidence that proves there are methodological design flaws of experimental comparative studies in ODE? The findings are: (1) Comparison of the overall weighted mean effect size indicated that student achievement in ODE was slightly higher with no significant difference between ODE
