Published: March 2017

CONTEXT AND OBJECTIVE Sodium excretion abnormalities in preeclampsia have been studied in relation to several factors. The objective of this study was to compare natriuria (mEq/24 h) and calciuria levels (mg/24 h) in preeclamptic patients. DESIGN AND SETTING An analytical cross-sectional study with a control group was conducted in the obstetric center and the high-risk pregnancy outpatient clinic at a university hospital in southern Brazil, and in a primary healthcare unit in the same city, including pregnant women with mild preeclampsia, severe preeclampsia or chronic hypertension, and women with normal pregnancies (14 patients in each group). METHOD Natriuria was measured using an ion-selective electrode in an automated clinical chemistry analyzer (Hitache 917, Roche). All the patients collected 24-hour urine, at home or at the hospital, for analysis of proteins, creatinine, calcium, sodium and uric acid. Quantitative variables with asymmetrical distribution were described using the median, minimum and maximum, and were compared using the Kruskal-Wallis test. The results were logarithmically transformed, with one-way analysis of variance (ANOVA) by ranks and then the post-hoc Tukey test, and were analyzed by means of the Spearman correlation and receiver operating characteristic (ROC) curve. The significance level used was 0.05. RESULTS There were significant differences between the groups in comparing severe preeclampsia with chronic hypertension and severe preeclampsia with controls (P < 0.0001 for both measurements). CONCLUSION Natriuria levels may be lower in preeclampsia when associated with calciuria. Natriuria assessment is an additional test for differential diagnosis of hypertensive diseases in pregnancy, but is a poor predictor when used alone.

Published: March 2017

Alzheimer's disease (AD) is characterized by impairments in memory and other cognitive functions such as language, which can be affected in all aspects including discourse. A picture description task is considered an effective way of obtaining a discourse sample whose key feature is the ability to retrieve appropriate lexical items. There is no consensus on findings showing that performance in content processing of spoken discourse deteriorates from the mildest phase of AD.OBJECTIVE:To compare the quantity and quality of discourse among patients with mild to moderate AD and controls.METHODS: A cross-sectional study was designed. Subjects aged 50 years and older of both sexes, with one year or more of education, were divided into three groups: control (CG), mild AD (ADG1) and moderate AD (ADG2). Participants were asked to describe the "cookie theft" picture. The total number of complete words spoken and information units (IU) were included in the analysis.RESULTSThere was no significant difference among groups in terms of age, schooling and sex. For number of words spoken, the CG performed significantly better than both the ADG 1 and ADG2, but no difference between the two latter groups was found. CG produced almost twice as many information units as the ADG1 and more than double that of the ADG2. Moreover, ADG2 patients had worse performance on IUs compared to the ADG1.CONCLUSIONDecreased performance in quantity and content of discourse was evident in patients with AD from the mildest phase, but only content (IU) continued to worsen with disease progression.

Trust in collaborative construction procurement strategies
Authors: Challender Jason
Published: March 2017

The aim of this study is to explore the extent to which trust is a viable tool in collaboratively procuring more successful UK further education construction strategies. A mixed-methods approach of quantitative and qualitative methodologies is adopted with the former using 79 survey questionnaires and subjecting data to correlation analysis. The research population is restricted to those contracting, consulting and client organisations that have had experience with collaboratively procured projects. Quantitative study findings have determined that there is a Pearson’s product moment correlation coefficient of 0·87 between all trust-building mechanisms and trust generated. Based on a p value of ≤0·05, it suggests a very strong influence between the two variables. Cronbach’s alpha test results revealed good reliability based on a coefficient of 0·79. Qualitative study findings inform the discussion of why organisations feel that certain trust-building mechanisms are particularly successful. These include incentive provisions, workshops, collaboration management systems, senior management commitment, open and joint communications and accounting policies. The study gives an understanding of how trust-building mechanisms can be designed and implemented for improving project outcomes. Future qualitative research is recommended to explore trust-building initiatives in developing a framework for increasing trust in partnering strategies.

Nowadays, clothes with various designs and color combinations are available for purchasing through an online shop, which is mostly equipped with keyword-based item retrieval. Here, the object in the online database is retrieved based on the keyword inputted by the potential buyers. The keyword-based search may bring potential customers on difficulties to describe the clothes they want to buy. This paper presents a new searching approach, using an image instead of text, as the query into an online shop. This method is known as content-based image retrieval (CBIR).  Particularly, we focused on using color as the feature in our Muslimah clothes image retrieval. The dominant color descriptor (DCD) extracts the wardrobe's color. Then, image matching is accomplished by calculating the Euclidean distance between the query and image in the database, and the last step is to evaluate the performance of the DWD by calculating precision and recall. To determine the performance of the DCD in extracting color features, the DCD is compared with another color descriptor, that is dominant color correlogram descriptor (DCCD). The values of precision and recall of DCD ranged from 0.7 to 0.9 while the precision and recall of DCCD ranged from 0.7 to 0.8. These results showed that the DCD produce a superior performance compared to DCCD in retrieving a set of clothing image, either plain or patterned colored clothes.

Introduction: Metabolic syndrome (MS) is an independent risk factor, which affects the development of chronic kidney disease, so the glomerular filtration rate (GFR) as an indicator of glomerular function in patients with and without MS who attended the outpatient clinic “los Grillitos, sector Caña de Azucar”. Materials and Methods: A comparative, correlational, cross-sectional study was conducted in a non-probability sample of convenience consisting of 60 patients with MS diagnosed according to the criteria Panel ATP III, and 60 apparently healthy individuals, whom the GFR was determined by the Cockcroft-Gault as well as clinical and biochemical parameters for the diagnosis of MS. Results: Out of the total patients evaluated, 37 (30.7%) showed alterations that put them in grades G2 and G3 system risk stratification of CKD, of these 18 and 19 corresponded to patients with and without MS respectively. Glomerular Hyperfiltration (> 120 mil / min) it was found in both groups 28 (46.7%) and 24 (40%) cases of patients with and without MS respectively. The glomerular function was strongly correlated with abdominal obesity and high levels of stress arterial. As for the number of criteria and its relationship to the level of kidney damage present, not a firm to increase the latter with respect to the first (p=0.385) trend was observed. Conclusion: The change in the glomerular function is not directly related to the MS but with its components, specifically abdominal obesity and hypertension.

Authors: Luna Selva Leticia , Lutz Mariane
Published: March 2017

Background: Chilean school children present a high prevalence of cardiovascular risk (CVR) factors related with bad eating practices and sedentary habits, including overweight and obesity. Objective: to evaluate the impact on RCV of improving the quality of meals delivered by State programs for school children and optimizing their physical activity. Methods: an intervention study was realized in 269 children of both sexes attending third basic grade during 2013 in Quillota, Chile. The subjects were randomized into four groups: Control (C, no intervention); Intervention in diet with the addition of dehydrated vegetables into desserts and jellies given at lunch (D); Intervention in physical activity, improving quantity and quality (PA); Intervention in diet and PA (DPA). Anthropometry and biochemical serum markers were assayed before and after the intervention. Results: no evidence of change in nutritional status as an effect of the interventions was observed during the annual school period. The level of triglycerides and VLDL-cholesterol augmented in the group C but not in the intervened groups. Plasma levels of total cholesterol, LDL-cholesterol and glucose did not differ in children from groups D, PA and DPA versus Control. Conclusion: even though the intervention of diet and/or physical activity in children during a school year was probably too short to support changes in the nutritional status, a reduction in some CVR factors may already be observed.

Introduction: the concept of food security and nutrition is based on the regular and sufficient access to food of adequate quality and it implies food safety as one of its dimensions. Objective: to analyze the sanitary and hygienic conditions of food handling in households in Chapecó (SC), Brazil. Materials and Methods: descriptive study with 138 households selected by systematic sampling to a 5% significance level and a 4% acceptable error. We applied a questionnaire to the person who was the responsible for food handling in each household. We used descriptive and inferential statistics and we interpreted the data according to health vulnerability framework. Results: we highlight that 50.7% (n=70) reported to just wash vegetables with water, 71% (n=98) reported to wash cutting boards with detergent and cold water, 33, 3% (n=46) reported the use of raw eggs. There was no association between the source of water supply and sanitary failures observed. Conclusions: safe food handling procedures are not adopted in a reasonable proportion of households, which may explain the vulnerability to foodborne diseases in these environments.

Introduction: The figure of the caregiver of dependent persons is today the subject of scientific research in various disciplines in the health and social sciences. However, the terminology used to refer to the caregiver is often confusing, especially when they are not health professionals. Purpose: To analyze the terminology used to refer to the figure of the unpaid caregiver without technical training in scientific publications in recent years. Methods: A two-stage analysis was conducted: (1) review of publications in national and international databases in 1996-2005 and 2006-2016, and (2) review 2006-2016 using specific Dialnet database filters. Results: Despite the more frequent use of "family caregivers" (in Spanish and English) in the publication titles, differences were observed in the use of other terms depending on the year of publication, the subject matter, type of journal or quality of the publication. Conclusion: The lack of agreement on the use of an established terminology to refer to the caregiver profile shows the need for constant revision and updating of the terms.

The advancement in science and technology has led to luffa sponge (LS) being widely used as a natural material in industrial application as its polyporous structure and light texture. In order to enhance the utility of LS fibers as the reinforcement of lightweight composite materials, this study investigate its water absorption, mechanical properties, anatomical characteristic and thermal performance. Hence, moisture regain, tensile properties of LS fiber bundles were measured in accordance with standards and the structural characteristics were investigated via microscopic observation. Scanning electron microscopy (SEM) was used to observe the surface morphology and fracture surface of fiber bundles. Test results shows that the special structure where the phloem tissues degenerate to cavities had a significant influence on the mechanical properties of LS fiber bundles. Additionally, the transverse sectional area occupied by fibers in a fiber bundle (SF), wall thickness and ratio of wall to lumen of fiber cell, and crystallinity of cellulose had an impact on the mechanical properties of LS fiber bundles. Furthermore, the fiber bundles density of LS varies range of 385.46-468.70 kg/m3, much less than that of jute (1360.40 kg/m3) and Arenga engleri (950.20 kg/m3) while LS fiber bundles has superior specific modulus.

Published: March 2017

Hepatitis E virus (HEV) is a common cause of acute hepatitis worldwide, accounting for approximately 25% of deaths among pregnant women. We previously reported that pregnancy serum facilitates HEV replication in vitro. However, the differences in host cells with HEV infection induced by pregnancy serum and fetal bovine serum (FBS) are unclear. In this study, differentially expressed proteins were identified in HEV-infected hepatoma cells (HepG2) supplemented with different sera by using isobaric tags for relative and absolute quantitation. Proteomic analysis indicated that HEV infection significantly induced 1014 differentially expressed proteins in HEV-infected HepG2 cells when supplemented with FBS compared with pregnancy serum. Further validation by Western blot confirmed that filamin A, heat-shock proteins 70 and 90, Cytochrome c, and Thioredoxin were associated with HEV infection. This comparative analysis provides an important basis to further investigate HEV pathogenesis in pregnant women and HEV replication.
Differential Degradation and Detoxification of an Aromatic Pollutant by Two Different Peroxidases
Authors: Alneyadi Aysha Hamad , Shah Iltaf , AbuQamar Synan F. , Ashraf Syed Salman
Published: March 2017

Enzymatic degradation of organic pollutants is a new and promising remediation approach. Peroxidases are one of the most commonly used classes of enzymes to degrade organic pollutants. However, it is generally assumed that all peroxidases behave similarly and produce similar degradation products. In this study, we conducted detailed studies of the degradation of a model aromatic pollutant, Sulforhodamine B dye (SRB dye), using two peroxidases—soybean peroxidase (SBP) and chloroperoxidase (CPO). Our results show that these two related enzymes had different optimum conditions (pH, temperature, H2O2 concentration...etc.) for efficiently degrading SRB dye. High-performance liquid chromatography and LC-mass spectrometry analyses confirmed that both SBP and CPO transformed the SRB dye into low molecular weight intermediates. While most of the intermediates produced by the two enzymes were the same, the CPO treatment produced at least one different intermediate. Furthermore, toxicological evaluation using lettuce (Lactuca sativa) seeds demonstrated that the SBP-based treatment was able to eliminate the phytotoxicity of SRB dye, but the CPO-based treatment did not. Our results show, for the first time, that while both of these related enzymes can be used to efficiently degrade organic pollutants, they have different optimum reaction conditions and may not be equally efficient in detoxification of organic pollutants.

Internet-Based Cultural Enrichment in the Polish Language Classroom
Authors: Kosmala Kinga , Houle Erik
Published: March 2017

Most introductory and intermediate textbooks for Polish, currently in use, are written in Poland and intended for intensive language study in-country where the “little-c” cultural component is inherent and immediate in an intensive language program. One of the most widely used textbooks in North America is the series, Hurra!!! po polsku I, II, III. This textbook is based on a communicative approach to language pedagogy and consists of thematic chapters according to aspects of life and culture in everyday society. The intent of the Hurra!!! po polsku series is that students will experience Poland while learning the language. This presents a problem to educators of Polish in the United States. Numerous communicative exercises presuppose acquaintance with the target culture while providing little in the way of input. We have found that students have difficulty relating to many exercises that carry specific cultural information. Our project is based on two specific goals: first, to decrease the amount of time spent in class to explain culture-specific aspects of the textbook; and second, to spare our students at least some amount of the usual culture shock one experiences when traveling to Poland. In this report, we describe a website, exercises, and activities we developed to accompany the textbook.

Poetic Texts in Polish Heritage Language Classes
Authors: Gąsienica Byrcyn Anna
Published: March 2017

The use of poetic texts in heritage Polish composition classes offers a resourceful, motivating, and original way of learning the language and culture, primarily by mastering writing skills and understanding Poland’s rich and complex culture. Moreover, poetic texts give an aesthetical beauty and moral values, and the students discover universal truths during their readings and discussions. A chosen poem, such as Adam Mickiewicz’s “Lelije” (Lilies), Teofil Lenartowicz’s “Złoty kubek” (A Golden Cup), or Bolesław Leśmian’s “Urszula Kochanowska” (Ursula Kochanowska), is presented in class for listening exercises, reading, recitation, discussion, and especially creative writing. The students are introduced to the captivating genre of poetry and learn about the cultural and historical content of this work. Then, they write their poem or a composition on the introduced theme. The assessment consists of the student’s originality, the content of the paper, the organization of the paper, and the employment of correct grammatical sentence structure and vocabulary.Consequently, poetic texts immersed in Polish intertextual space are open and may be read in many ways, beyond their initial context, presenting many fascinating interpretations and offering many intellectual attractions. A poem is an excellent learning source for the creativity stage in the art of writing, transmuting elements of the past Polish culture and literature in modern language classes. Students write their own intriguing stories, focusing on their knowledge of the language, and using resourcefulness and creativity.

Published: March 2017

Purpose

The structure and development of an innovative, ASHP-accredited postgraduate year 2 (PGY2) clinical pharmacogenetics residency program are described.

A 12-month PGY2 clinical pharmacogenetics residency was created at St. Jude Children’s Research Hospital in accordance with the ASHP standards for advanced practice residencies. The purpose of this 12-month residency program is to prepare pharmacy residents to implement pharmacogenetics in clinical practice. The program helps residents develop expertise in the science of pharmacogenetics as well as an understanding of translational research, innovative pharmacy practice model development, and clinical informatics. The resident learns to optimize patient outcomes through the expert provision of evidence-based, patient-centered precision medicine as an integral part of an interprofessional team. After completing the program, residents are expected to have the clinical skills necessary to practice in the field of clinical pharmacogenetics and independently implement pharmacogenetic testing in other health-system settings. Because implementation of pharmacogenetics requires collaboration across many disciplines, residents works within an interprofessional team of physicians, nurses, informatics specialists, pharmacists, and clinical laboratory personnel to achieve program goals. Since the first resident graduated in 2012, the program has graduated 1 resident each year. Graduated residents have accepted pharmacogenetics positions at major academic medical centers and community hospitals, as well as academic and research positions with a pharmacogenetics emphasis.

Conclusion

A PGY2 clinical pharmacogenetics residency was successfully developed at St. Jude in 2013. After completion of the program, residents are equipped with the clinical skills and necessary experience to drive precision medicine forward and lead the implementation of pharmacogenetic testing in other healthcare settings.

Authors: Caudeli Tomé Jesús , García Rueda José Jesús
Published: March 2017

El Docusquema representa un nuevo modelo para construir presentaciones multimedia destinadas al aprendizaje basándose en los principios del Aprendizaje Receptivo Significativo. Este modelo otorga mayor protagonismo a la imagen y el sonido frente al texto escrito tradicional. En este proyecto se ha definido un lenguaje para describir los Docusquemas utilizando XML, y se han desarrollado dos herramientas software utilizando el lenguaje Java. La función de la primera de ellas es generar y editar Docusquemas, mientras que la segunda es un applet que permite reproducirlos a través de Internet, integrando las presentaciones en páginas web.Development of Environments for the Creation and Display of Docuschemas.AbstractDocuschemas are a new model for the construction of multimedia, learning oriented presentations based on the Meaningful Receptive Learning.

Tras la primera formulación en 1995 sobre qué es una Web Quest ¿cuál es el estado de su desarrollo en el campo de la educación? Esta pregunta exige muchas miradas y respuestas. Este trabajo busca ser parte de esta evaluación poniendo en evidencia el desarrollo de la producción científica sobre WebQuest en las dos principales bases de datos científicas: WOS (Web of Science) y Scopus desde su formulación hasta la actualidad (1995-2014). El método es el análisis bibliométrico en base a las siguientes variables: número de artículos publicados, número de citas recibidas, principales revistas citantes, promedio de citas por año, nombre y país de los autores más citados y palabras clave. Se ha procedido a la identificación del perfil y las características de las publicaciones científicas que lo tratan, sobre la conclusión de una evidente dispersión y atomización de resultados, destacando la existencia de una significativa comunidad científica sobre Webquest en España.
