title: Association between Dietary Glycemic Index and Excess Weight in Pregnant Women in the First Trimester of Pregnancy

description: Abstract Objective To assess the association between dietary glycemic index (GI) and excess weight in pregnant women in the first trimester of pregnancy. Methods A cross-sectional study in a sample of 217 pregnant women was conducted at the maternal-fetal outpatient clinic of the Hospital Geral de Fortaleza, Fortaleza, state of Ceará, Brazil, for routine ultrasound examinations in the period between 11 and 13 weeks + 6 days of gestation.Weight and height were measured and the gestational body mass index (BMI) was calculated. The women were questioned about their usual body weight prior to the gestation, considering the prepregnancy weight. The dietary GI and the glycemic load (GL) of their diets were calculated and split into tertiles. Analysis of variance (ANOVA) or Kruskal-Walls and chi-squared (χ2) statistical tests were employed. A crude logistic regression model and a model adjusted for confounding variables known to influence biological outcomes were constructed. A p-value &lt; 0.05 was considered significant for all tests employed. Results The sample group presented a high percentage of prepregnancy and gestational overweight (39.7% and 40.1%, respectively). InthetertilewiththehigherGIvalue, therewasa lower dietary intake of total fibers (p = 0.005) and of soluble fibers (p = 0.008). In the third tertile, the dietary GI was associated with overweight in pregnant women in the first trimester of gestation, both in the crude model and in the model adjusted for age, total energy intake, and saturated fatty acids. However, this association was not observed in relation to the GL. Conclusion A high dietary GI was associated with excess weight in women in the first trimester of pregnancy.

description: Abstract Background: Distress has a potentiating effect on complications of heart disease. Early identification of distress and psychosocial management could help patients to deal with the disease and improve their quality of life. However, in Brazil, there is no specific instrument for evaluation of distress in cardiac patients. Objectives: To describe the validation process of the Screening Tool for Psychosocial Distress (STOP-D) for the Brazilian population. Methods: Cross-sectional, observational study with a quantitative approach. A total of 144 patients (including outpatients and inpatients) were interviewed at the waiting room of the outpatient cardiology clinic or in cardiology wards. Sociodemographic and clinical data were collected, and distress was assessed using two instruments - the Brazilian version of the STOP-D and the Hospital Anxiety and Depression Scale (HADS). First, we performed an exploratory factor analysis and analysis of the accuracy of the STOP-D score by the receiver operating characteristic (ROC) curvet. Results: The factorability analysis of the correlation matrix did not detect any factor that made the factorial solution unfeasible. The instrument showed a single-factor nature, confirmed by the criterion of eigenvalues, with an 85% accuracy in predicting distress. A cut-off point of 15.5 was chosen for distress using the ROC curve. Conclusions: The Brazilian version of the STOP-D is an adequate instrument for the screening of heart disease patient for distress. It can be easily used by any health professional and would contribute to the promotion of a comprehensive support to cardiac patients.

title: Assessment methodology for Lean Practices in healthcare organizations: case study in a Brazilian public hospital

description: Abstract Paper aims This article aims at proposing a methodology for assessing lean practices in healthcare organizations that are undergoing a lean implementation. Originality The proposed methodology evaluates healthcare organizations and help managers identify the relationships intensities between their problems and lean practices. This application occurs in a case study in an Emergency Department from a Brazilian public hospital. Research method The proposed methodology provides a theoretical framework that addresses lean practices according to fundamental aspects of the organization, such as people, partnerships, results, processes and leadership, corroborating to a systemic view of lean implementation and facilitating its long-term sustainability. Main findings Our findings provide guidelines for the public hospital leadership, allowing a clear focus on the improvement efforts that can mitigate problems. Implications for theory and practice Due to contextual diversity, the understanding of the critical success factors for lean implementation under such conditions deserves attention. Hence, the proposed method allows practitioners and academics to better comprehend the lean implementation within healthcare organizations. Such enhanced comprehension allows to anticipate potential issues throughout the lean implementation, entailing more assertive efforts. Moreover, accounting for specific problems when designing the lean implementation avoids the utilization of a general and ineffective approach.

title: Association between Morphodynamic Variables by Transesophageal Echocardiography and CHA2DS2-Vasc Values

description: Abstract Background: In atrial fibrillation (AF), the CHA2DS2-VASc score calculates the risk for stroke. Di Biase classified the left atrial appendage (LAA), using magnetic resonance imaging, into 4 morphological types and correlated it with cerebrovascular events. Transesophageal echocardiography (TEE) also evaluates LAA and is a more widespread technique. Objective: To evaluate, using TEE, the possibility of characterizing LAA and to analyze its morphological aspects using the CHA2DS2VASc score. Methodology: A total of 247 patients were divided into three groups considering the CHA2DS2-VASc score: Group 1: 0 and 1; Group 2: 2 and 3 and, Group 3: ≥ 4 points. TEE produced the echocardiographic data. LAA was classified into thrombogenic and non-thrombogenic morphologies. In the analysis of statistical tests, a significance level of 5% was adopted. Results: The average age was 50 and 16.2% presented AF. In Group 1, we observed normal variables with a lower prevalence of AF (8.7%, p &lt; 0.001). In group 2, spontaneous contrast was detected in 26.7%, (p &lt; 0.001), thrombus in 6.7% (p = 0.079) and flow velocity in LAA &lt; 0.4 m/s in 22.7% (p &lt; 0.001) of the cases. Group 3 presented the highest percentages of AF (31.8%, p &lt; 0.001), stroke/TIA (77.3%, p &lt; 0.001), EF &lt; 55% (18.2%, p = 0.010) and higher prevalence of thrombogenic type LAA (72.7%, p = 0.014). A higher occurrence of stroke/TIA was observed in patients with thrombogenic LAA (25.2%) compared to the non-thrombogenic group (11.2%), (p = 0.005). Conclusions: The thrombogenic morphology of LAA identified in TEE presented a higher risk of stroke regardless of the CHA2DS2VASc score. Patients with higher scores had greater abnormalities in echocardiographic variables.

title: A methodological proposal for the analysis of Cladocera (Crustacea, Branchiopoda) subfossils from sediments of temporary aquatic ecosystems

description: Abstract The main objective of the present study was to promote some adaptations to the standard methodology used in the analysis of Cladocera subfossils. The samples used in this study were collected at Lagoa dos Coutos, a temporary lake located on an outcrop with iron-rich duricrust in the Serra do Gandarela (Minas Gerais, Brazil). The sediment from this pond, typical of temporary ecosystems in the region, is characterized by rigid concretions that are difficult to dissolve in aqueous media, making it difficult to visualize and analyze subfossils taxa. Sediment samples were prepared according to the standard methodology used in paleolimological studies and the methodological adaptations proposed in the present study, which included the addition of 1 mg of Kochia scoparia, a palynological marker used to estimate subfossil density, as well as the addition of hydrofluoric acid (HF) to oxidize silicate materials. The samples prepared according to the new methodological procedure improved Cladocera subfossil visualization, facilitating the taxonomic analysis of the species. The samples submitted to the standard methodological procedure had a significantly higher mean of sediment particles (mean of 84.2 sediment particles) and 70% more residues compared to the samples prepared with the newly proposed methodology (mean of 22.1 sediment particles). Absolute data on the temporal variation of the density of Cladocera subfossils was obtained by using the palinological marker K. scoparia, which showed higher densities of subfossils in more recent, humid periods (112,000 subfossils/cm3 at 5 cm, equivalent to 3,500 years BP). The results indicate that the new methodology can contribute to advances in paleolimnological studies of temporary aquatic ecosystems, whose lake histories are rarely investigated, despite their ecological relevance as ecosystems that indicate environmental and climatic changes.

title: Reaction of wild Solanaceae rootstocks to the parasitism of (Meloidogyne javanica)

description: ABSTRACT Intensive production of vegetables in greenhouses can increase the amount of inoculum of soil-borne pathogens, such as the root-knot nematode. Thus, in this study we aimed to evaluate the potential of Solanaceae as rootstocks resistant to Meloidogyne javanica nematodes as an alternative to tomato grafting. The experiment consisted of seven treatments: wild species joá-vermelho (Solanum capsicoides), joá-bagudo (Solanum palinacanthum), joá-bravo (Solanum viarum), jurubeba (Solanum spp.) and the commercial tomato cultivars Santa Cruz Kada, Batalha and Guardião. The analyzed variables were gall index; egg mass index; final nematode population; reproduction factor (FR) and reaction: susceptibility, resistance and immunity; fresh shoot and root mass and number of eggs per gram of roots. The wild species joá-vermelho, joá-bagudo and jurubeba showed resistance, with the lowest indexes of galls, egg mass, final population of nematodes and number of eggs per gram of root, not differing from the resistant control treatment (hybrid rootstock Guardião), with a reproduction factor less than 1, showing potential to be used as a resistant rootstock to M. javanica. Joá-bravo species showed susceptibility to the root-knot nematode, with a FR&gt;1, not differing from the susceptible tomato Santa Cruz Kada. These results confirm the resistance of wild species to nematode parasitism, which can prove the viability of use as possible alternative rootstocks, and reinforce the idea that more studies should be carried out aiming to provide more viable options for farmers and plantlet producers.

title: Antimicrobial Resistance and Molecular Characterization of Salmonella Enterica Serotypes Isolated from Poultry Sources in Brazil

description: ABSTRACT Salmonella spp. remain among the most important agents of foodborne diseases worldwide. The importance of Salmonella spp. in public health is linked to their wide range of antimicrobial resistance and to their pathogenicity and virulence in both human and animal hosts. The aim of this study was to determine the antimicrobial resistance patterns for Salmonella serotypes isolated from poultry sources in Brazil and to detect virulence-associated genes and verify their association with specific serotypes. A total of 163 strains of Salmonella enterica isolated from poultry sources in Southern Brazil were selected, and each belonged to one of 11 different serotypes. They were tested against ten antibiotics and examined for the presence of 26 virulence-associated genes by PCR. S. Typhimurium, S. Bredeney, S. Schwarzengrund and S. Tennessee showed the highest overall resistance rates. Approximately 18% of Salmonella strains were classified as multidrug-resistant strains. Our results indicate associations between antimicrobial resistance and specific serotypes. Most of the investigated genes presented a high frequency and a regular distribution, regardless of the serotype. Eight genes are positively or negatively associated with at least one serotype. The observed associations between antimicrobial resistance and specific serotypes are useful in developing specific control and treatment measures for each serotype. Despite the virulence genes being evenly distributed among the serotypes, some of these genes are associated with specific serotypes, and sefA, sopEand lpfA were selected as possible markers of Salmonella serotypes.

title: ONLINE PRESENCE AS AN ELEMENT OF ANALYSIS OF THE SCHOOL/COMUNITY RELATION. THE UNIDADES EDUCATIVAS DEL MILENIO CASE ON TWITTER

description: ABSTRACT: Presentiality, originally tangible and uni-located, now has an asynchronous and multi-situated character. People and groups create complex presentialities, inhabiting online and offline social spaces in a continuum without sutures. The consideration of spatiality as an integrated dimension is a long-standing epistemological position. The objective of this article is to explore how the Unidades Educativas del Milenio - UEM build their Twitter presentiality to link with the community. We used qualitative, descriptive and analytical method based on analysis of social networks to analyze the Twitter accounts directly referred to these institutions and, later, the network maps generated by the UEM were described as an object of dialogue. Results show that only 11 out of 97 UEM have Twitter accounts, of those, only two have a frequent activity. Additionally, the UEM generate atomized spaces of discussion, and its mentions are conjunctural and mainly referred to reports from state entities.
