title: Use of HAS-BLED Score in an Anticoagulation Outpatient Clinic of a Tertiary Hospital

description: Abstract Background: HAS-BLED score was developed to assess 1-year major bleeding risk in patients anticoagulated with vitamin K antagonists (VKA) due to atrial fibrillation (AF). Objective: Of this study was to assess the ability of HAS-BLED score and its components to predict major bleeding in patients treated in an anticoagulation outpatient clinic of a tertiary hospital. Methods: A retrospective cohort study on AF patients treated with VKA was conducted. Logistic regression analysis was performed to evaluate the ability of individual score components to predict major bleeding. The significance level adopted in all tests was 5%. Results: We studied 263 patients with a mean age of 71.1 ± 10.5 years over a period of 237.6 patients-year. Median HAS-BLED score was 2 (1-3). The overall incidence of major bleeding was 5.7%, and it was higher among high-risk HAS-BLED score patients than in low risk patients (9.6 vs. 3.1%; p = 0.052). Area under the ROC curve was 0.70 (p = 0.01). Cut-off point ≥ 3 showed sensibility of 66.7%, specificity of 62.1%, positive predictive value of 9.6% and negative predictive value of 96.9%. Major bleeding-free survival was lower in high-risk group (p = 0.017). In multivariate analysis, concurrent antiplatelet use was the only independent predictor of major bleeding among score components (OR 5.13, 95%CI: 1.55-17.0; p = 0.007). Conclusion: HAS-BLED score was able to predict major bleeding in this cohort of AF patients. Among score components, special attention should be given for concomitant antiplatelet use, which was independently associated to this outcome. Antiplatelets in AF patients under VKA anticoagulation should be used in selected patients with favorable risk-benefit assessment.

title: Leprosy after release from treatment in the Brazilian Unified Health System: aspects for access in the Northeast region

description: Universal access to health services represents a complex process of inter-relationships between users and health services. In a broader sense it includes economic, technical, political and symbolic aspects. For neglected diseases such as leprosy, this is a major challenge. This cross-sectional study aims to characterize access to health care services for people affected by leprosy after release from treatment in the cities of Sobral and Fortaleza. The study included a representative sample 10% of those concluding treatment from 2003 to 2005 (304 cases). Participants were characterized regarding socio demographic and clinical variables and access to health services after release from treatment. The study population was mostly male (58%), physical disabilities (34%) and with leprosy reactions (37%). The biomedical approach of leprosy reactions contemplated in large part to search for and supply of care in this period. The access to care after discharge was particularly weak in rehabilitative interventions such as surgery and psychological attention. We identified important gaps in the operationalization of attention to people affected after release from treatment in both cities. The date also shows the negligence of leprosy as a chronic condition and the resulting difficulties regarding on integrated distance to the comprehensive approach to people with leprosy after release from treatment in the Unified Health System (SUS).

title: Characterization of reservoirs for water supply in Northeast Brazil using high resolution remote sensing

description: ABSTRACT This paper reports the application of information acquired by aerial survey to characterize water supply reservoirs in the Pajeú River Basin (Pernambuco State/Brazil). The survey was carried out with digital cameras of high spatial resolution and laser relief profiling (LiDAR technology). Two areas were selected to apply the remote sensing products. Small reservoirs in the Quixaba Creek Basin were identified based on their topographic characteristics. Given that the small reservoirs are “depressions” in the terrain, they can be “filled”, resulting in a new Digital Terrain Model (DTM). The difference between the filled DTM and the original DTM makes it possible to identify the reservoirs. A summary of the results is: 61 reservoirs were correctly detected; 18 reservoirs were not detected; 13 reservoirs were detected erroneously. In another application, the storage capacity of the reservoirs belonging to the hydrosystems of Pajeú River Basin was estimated. The storage in these reservoirs and maximum surface area were estimated using DTM and geoprocessing tools. From the total of 31 reservoirs evaluated, eight were completely empty at the time of the LiDAR data collection. The official registers reported 83.83 million m3 for the storage capacity of these eight reservoirs, whereas our applications estimated the value at 70.23 million m3. This difference is explained by the loss of volume in the reservoirs due to the process of sediment transport.

title: EXOTIC ARBUSCULAR MYCORRHIZAL FUNGI AND NATIVE DARK SEPTATE ENDOPHYTES ON THE INITIAL GROWTH OF Paspalum millegrana GRASS

description: ABSTRACT Arbuscular mycorrhizal fungi (AMF) and dark septate endophytic fungi (DSE) promote increase in plant biomass, depending on the soil and climate conditions and the interactions with the host plant. The objective of this study was to evaluate the interaction of exotic arbuscular mycorrhizal fungi and native DSE fungi on the initial growth of P. millegrana. A completely randomized experimental design comprising the Paspallum millegrana cutilvar with the following treatments: control - without AMF, and three exotic AMF isolates (UFLA351 - Rhizoglomus clarum, UFLA372 - Claroideoglomus etunicatum and UFLA401 - Acaulospora morrowiae), with four replications each. P. millegrana grass was colonized by exotic AMF by R. clarum (UFLA351, 11.9%), C. etunicatum (UFLA372, 39.6%), and A. morrowiae (UFLA401, 51.2%). P. millegrana was also colonized by native DSE fungi, but these did not interfere with the colonization by exotic AMF and plant development. P. millegrana is responsive to the inoculation of UFLAs isolates of exotic AMF, which may contribute to the grass growth and survival under field conditions. The process of surface disinfestation of seeds does not eliminate endophytic microorganisms, whose presence may influence plant colonization by AMF, as well as development of the host plant.

title: Disruptive Technology and Disruptive Law: Understanding the Law in a New Technologies scenario

description: Abstract The article deals with the correlation between New Technologies (disruptive) and Law (which should also be disruptive), bringing a proposal for decision making on social complexities in a post-hyper-trans-modern era. The scientific paradigm of complexity, which is explicit as a measure of risk, has developed a paradigm for complexity, which has made explicit the deregulation process, developed problem management strategies, generated risks and generated new technologies. The work is sought to understand the law and technologies Information and information technologies for social enterprises, focused on the response to problems, risks and the possibilities brought about by disruptive technological phenomena. The relevance of the discussion lies in the fact that the impacts of new technologies have a direct impact on human existence in its psyche and techné, unveiling itself through social complexities, and demanding a disruptive right that becomes fundamental for the prevention and management of risks generated technological phenomena.

title: Assessment of Central Blood Pressure and Arterial Stiffness in Practicing Long-Distance Walking Race

description: Abstract Background: An ecological hiking occurs yearly in Brazil. It is a unique event because of its distance (310 km) and dynamics (mean of 62 km/day for 5 days with mean pace of 7.6 km/h). Although beneficial effects of moderate-intensity exercises are well-known, the effects of intense and long-duration exercise still require study. Objective: To evaluate the effects of mixed walking/running race on various blood pressure (BP) parameters 30 days before (A0), on the 2nd (A2), 3rd (A3), and 4th (A4) days after completing the day's stage. Methods: Central systolic (cSBP) and diastolic BP (cDBP), peripheral systolic (pSBP) and diastolic BP (pDBP), central pulse pressure (cPP), peripheral pulse pressure (pPP), amplified pulse pressure (aPP), corrected augmentation index (AIx75%) and pulse wave velocity (PWV) were measured using an oscillometric Mobil-O-Graph® (IEM, Stolberg, Germany) in 25 male athletes (mean age of 45.3 ± 9.1 years). A p value &lt; 0.05 was considered a statistically-significant difference. Results: cSBP decreased from A0 to A2 (109.5 to 118.1 mmHg) and from A0 to A3 (109.5 to 102.5 mmHg); pPP decrease from A0 to A2 (49.2 to 38.2 mmHg) and from A0 to A4 (49.2 to 41.2 mmHg); aPP decrease from A0 to A1 (15.6 to 9.5 mmHg), from A0 to A2 (15.6 to 8.0 mmHg) and from A0 to A3 (15.6 to 11.2 mmHg). PWV correlated with age. Conclusions: Blood pressure dropped on the first days of the race and returned to close to baseline values at the end. PWV correlates strongly with age. This type of exercise promotes effects on BP and PWV similar to those seen in long-duration, high-intensity sports. These changes in trained healthy individuals do not seem to increase cardiovascular risks. This was the first study to assess the effects of this type of exercise on the cardiovascular system.

title: Ranganathan and the faceted classification theory

description: Abstract The present study contextualizes Ranganathan’s main theoretical contributions to the classification theory and addresses the Five Laws of Library Science. The major milestones in philosophical and bibliographic classifications are presented to show that the classification system has evolved from purely philosophical schemes, which were focused on the systematization of knowledge, into modern bibliographic classification systems. Facet analysis is considered a contribution to the classification process since it allows the use of an approach that encompasses different points of view of the same subject, as opposed to the enumerative systems. This article also discusses Ranganathan’s five fundamental categories, known as Personality, Matter, Energy, Space and Time, and points out to criticism of this form of categorization in the literature. The Spiral of Scientific Method and the Spiral Model of Development of subjects are presented; the latter is the meta-model of the former. The Colon Classification, which was first published in 1933, was also discussed. Finally, the applicability of the faceted classification in today’s world was addressed.

title: Ontology lexicalization: Relationship between content and meaning in the context of Information Retrieval

description: Abstract The proposal presented in this study seeks to properly represent natural language to ontologies and vice-versa. Therefore, the semi-automatic creation of a lexical database in Brazilian Portuguese containing morphological, syntactic, and semantic information that can be read by machines was proposed, allowing the link between structured and unstructured data and its integration into an information retrieval model to improve precision. The results obtained demonstrated that the methodology can be used in the risco financeiro (financial risk) domain in Portuguese for the construction of an ontology and the lexical-semantic database and the proposal of a semantic information retrieval model. In order to evaluate the performance of the proposed model, documents containing the main definitions of the financial risk domain were selected and indexed with and without semantic annotation. To enable the comparison between the approaches, two databases were created based on the texts with the semantic annotations to represent the semantic search. The first one represents the traditional search and the second contained the index built based on the texts with the semantic annotations to represent the semantic search. The evaluation of the proposal was based on recall and precision. The queries submitted to the model showed that the semantic search outperforms the traditional search and validates the methodology used. Although more complex, the procedure proposed can be used in all kinds of domains.

title: NATIVE MICROBIOTA AND ARBUSCULAR MYCORRHIZAL FUNGI ON GROWTH OF Paspalum millegrana SCHRAD

description: ABSTRACT Paspalum millegrana grass is a member of the family Poaceae native to the Americas, whose interaction with native symbiotic fungi has not yet been reported. The objective of this study was to evaluate the interactions between the native microorganisms and arbuscular mycorrhizal fungi in the development of P. millegrana Schrad. The experimental design was completely randomized with seven treatments (control, without AMF; native microbial inoculant; native + UFLA05 Gigaspora albida; native + UFLA351 Rhizoglomus clarum; native + UFLA372 Claroideoglomus etunicatum; native + UFLA401 Acaulospora morrowiae, and a mix of all treatments). The substrate was autoclaved sand and coconut powder at 2:1, with eight repetitions. The variables analyzed were: mycorrhizal colonization, dark septate endophytic fungi colonization, number of mycorrhizal spores, dry shoot mass, dry root mass, root length and volume, number of tiller and mycorrhizal dependence. Mycorrhizal arbuscular fungi and dark septate endophytic fungi colonized P. millegrana. The sporulation of arbuscular mycorrhizal fungi associated with P. millegrana was influenced by mycorrhizal colonization, depending on the fungus-plant interaction. P. millegrana was responsive to native + UFLA05 and native + UFLA351. No correlation between tiller emergence and mycorrhizal colonization of P. millegrana was observed.
