title: A NEW ESTIMATE FOR BRAZILIAN VERTICAL DATA OFFSET BASED ON GLOBAL GEOPOTENTIAL MODELS AND HEIGHT DETERMINATIONS THROUGH RELATIVE APPROACH

description: Abstract This paper aims to present a new estimate for the vertical offset between both Brazilian vertical data: DVB-I, in Imbituba-SC, and DVB-S, in Santana-AP. Brazilian Fundamental Altimetric Network (BFAN) currently has over 69000 stations with known normal-orthometric heights; 472 of these stations are connected to a tide gauge located in Santana-AP, at the North portion of Brazil, and the other ones are connected to a tide gauge located in Imbituba-SC, at the South portion of Brazil and considered Brazilian's main vertical reference. The vertical offset estimate is based on comparisons between reference and calculated normal-orthometric heights from values obtained arising of discrete GNSS observations on BFAN benchmarks, normal-geoid heights calculated from GGM XGM2016, which has proven to better model this variable in the region, and through a relative approach for heights determination, which has also proven to be the best way to handling the appropriate variables. As a result, a vertical offset of 1.32 m ± 0.07 m was obtained, which is coherent to previous studies performed in the same intent. This study up-comes as a new validation of the employed methodology itself, by achieving satisfactory results through independent manipulation even with low quality of input data for the region.

title: Evaluation of MEWDS-like lesions with fluorescein angiography and its frequency at an ophthalmic emergency department in Rio de Janeiro

description: ABSTRACTPurpose:To characterize multiple evanescent white dot syndrome (MEWDS)-like lesions as diagnosed by clinical exam and fluorescein angiography (FA) to build an epidemiological profile of this disease and highlight the most common angiographical aspects. It is important to emphasize the existence of this syndrome and improve patients’ information about the natural good course of this disease.Methods:A cross-sectional study including all FA performed from July 2006 to October 2012 (6,111 exams analyzed) in patients at our ophthalmic emergency department, with analysis of the different angiographic aspects of the MEWDS-diagnosed cases.Results:Among the 6,111 angiographies analyzed, 15 MEWDS cases were detected; the patients ranged in age from 13 to 42 years old, and the male/female ratio was 60% to 40% (nine male and six female). The most common FA aspects included hyperfluorescent dots, dots and spots in the retinal mid-periphery, and foveal granularity in 46% of the cases.Conclusions:MEWDS has a good prognosis, with spontaneous involution, which makes it difficult to diagnose because of the delayed access to ophthalmological assistance, in special FA examination, which highlights the lesions. This study was possible due to the quick access facility at a private ophthalmic emergency department and examination by an experienced ophthalmologist, along with complementary diagnosis by FA and better perception of the patients, thus ensuring good prognosis.

title: Nectar dynamics and reproductive biology of Passiflora actinia Hook. (Passifloraceae) in Araucaria Forest

description: ABSTRACT Nectar production has an important role in pollinator attraction and successful fruit production in many self-incompatible angiosperm groups. The reproductive biology of Passiflora actinia was studied here and related to nectar dynamics. Passiflora actinia presented a temporal segregation of male and female functions at the beginning of anthesis. Due to the movements of floral verticils, the anthers were positioned in a way that favors pollination two hours before the stigmas reached the same position. The nectary consisted of an epidermis with stomata and a parenchyma rich in starch, which was hydrolyzed during anthesis. The nectary organization is probably associated with the continuous production of nectar during anthesis as well as with the high mean nectar concentration. Hand pollination tests indicated that Passiflora actinia is obligately xenogamous, depending on large bees for pollination, specifically the carpenter bee Xylocopa augusti. The continuous production of nectar may increase the number of bee visits, thus favoring pollen flow.

title: Outcomes of cataract surgery in diabetic patients: results of the Pan American Collaborative Retina Study Group

description: Purpose: This study was designed to evaluate the visual and anatomical outcomes after cataract surgery in diabetic patients with different intraoperative therapeutic strategies. Methods: The research design comprised of a multicentric, retrospective, interventional study conducted at 6 centers in Argentina, Brazil, Costa Rica, Puerto Rico, Spain, and Venezuela. We included 138 diabetic patients with at least 6-month follow-up following phacoemulsification and intraocular lens implantation. Best-corrected visual acuity (BCVA) and central subfield thickness were collected at baseline and at 1-, 2-, 3-, and 6-month follow-up. Of these, 42 cases were not treated with any intraoperative coadjuvant medication (Group 1), 59 patients received intraoperative bevacizumab (Group 2) and 37 patients received intraoperative triamcinolone (4 mg/0.1 ml) (Group 3). Results: The mean logMAR [± standard deviation (SD)] BCVA improved from 0.82 (± 0.43) at baseline, to 0.14 (± 0.23) at 6-month follow-up (p&lt;0.001) in Group 1; from 0.80 (± 0.48) to 0.54 (± 0.45) (p&lt;0.001) in Group 2; and from 1.0 (± 0.40) to 0.46 (± 0.34) (p&lt;0.001) in Group 3. The mean central subfield thickness increased from 263.57 µm (± 35.7) at baseline to 274.57 µm (± 48.7) at 6-month follow-up (p=0.088) in Group 1; from 316.02 µm (± 100.4) to 339.56 µm (± 145.3) (p=0.184) in Group 2; and from 259.18 µm (± 97.9) to 282.21 µm (± 87.24) (p=0.044) in Group 3. Conclusion: Diabetic patients may significantly benefit from cataract surgery. This study provides evidence to support the use of intravitreal triamcinolone or bevacizumab at the time of cataract surgery in cases with pre-existent diabetic macular edema or moderate-severe non-proliferative diabetic retinopathy.

title: Aerobic bacterial microbiota of the conjunctiva in diabetic patients with normal and altered glycated hemoglobin levels in two regions in Brazil

description: Purpose: To study the aerobic bacterial microbiota of the conjunctiva in diabetic patients with regard to the management of diabetes, assessed using glycated hemoglobin levels. Methods: A cross-sectional study was conducted using conjunctival smears of diabetic patients from both sexes and with different ages, residing in two different Brazilian cities (Sorocaba and Rio Branco). A control group of non-diabetic patients was also included. The diabetic patients were considered to have controlled diabetes when their glycated hemoglobin level was ≤7% and blood glucose level was ≤126 mg/dL. Patients with non-controlled diabetes were those with glycated hemoglobin levels &gt;7% and blood glucose levels &gt;126 mg/dL. The samples obtained were inoculated in Brain-Heart Infusion broth and in culture media for aerobic bacteria (blood and chocolate agars); bacterial growth was evaluated in a microbiology laboratory. Results: A total of 120 eyes of 120 patients were included in the present study. The percentage of cultures in which bacterial growth was observed was greater in diabetic patients, although the difference was not statistically significant (p=0.103). There was a greater trend toward bacterial growth in the conjunctiva of diabetic patients with altered fasting blood glucose. There was no difference in the frequency of bacterial growth on the conjunctiva between diabetic patients with normal or altered glycated hemoglobin levels. In Sorocaba, conjunctival bacterial growth was similar to that observed in Rio Branco. The microorganism most frequently detected in the present study was Staphylococcus epidermidis, followed by Staphylococcus aureus, Proteus mirabilis, and Escherichia coli. Conclusion: There was no difference between diabetic patients with normal or altered glycated hemoglobin levels. The microorganisms found were similar to those found in studies investigating the conjunctival bacterial flora of diabetic and non-diabetic patients.

title: Multiplex polymerase chain reaction as an improved method for screening Histoplasma capsulatum mating types

description: Histoplasmosis is a systemic mycosis infection caused by Histoplasma capsulatum, a heterothallic ascomycete. The sexual reproduction of this fungus is regulated by the mating type (MAT1) locus that contains MAT1-1 and MAT1-2 idiomorphs, which were identified by uniplex polymerase chain reaction (PCR). This study aimed to optimise single-step multiplex PCR for the accurate detection of the distinct mating types of H. capsulatum. Among the 26 isolates tested, 20 had MAT1-1 genotype, while six showed MAT1-2 genotype, in agreement with the uniplex PCR results. These results suggest that multiplex PCR is a fast and specific tool for screening H. capsulatum mating types.

title: HUMAN RIGHTS FOR WHOM? PUBLIC POLICIES AND SPATIAL MANAGEMENT OF URBAN POVERTY REPRESENTED IN O GLOBO

description: ABSTRACT In the project "Media representation of the violation of rights and violence against street people in online journalism" (CNPq 304075/2014-0) we map and analyze representations of homelessness in the discursive production of three national online newspapers - Folha de S. Paulo, O Globo and Correio Braziliense. In order to do so, a comprehensive mapping of these online publications was carried out, collecting all the texts published during the period considered for the research - from 2011 to 2013 - that resulted from searches by keywords, leading to 750 texts. This article takes a partial focus of these data, exploring how O Globo represents the homeless population in news thematizing public policies. The texts were analyzed in their verbal and visual aspects, with tools from critical discourse analysis and the grammar of visual design. The analytical results point to the emphasis of the news in the occupation of the public space, both in the images and in the verbal texts, and the naturalization of the unequal distribution of resources and the segregation of classes, through the locative relations that are designed. There are privilege spaces that are impenetrable to population segments like homeless people. Inequality is normalized, including by the use of irony, in the case of verbal texts.

title: Curricular Integration from Analysis of a Discipline in a Medical Course

description: ABSTRACT The analysis of curricular practices has been an increasingly present activity in scientific production in the field of curriculum, mainly because in them the relations established between the knowledge, the prescribed curriculum and its accomplishment in the educational routine are aligned. In the field of medical education this analysis acquires special value, given the incipient production of works that evaluate pedagogical practices from a curricular point of view. Thus, we present the critical analysis of a curricular practice carried out in a discipline of a Medicine school, which is pertinent for presenting new looks about practice as a living expression of the curriculum in action. From the thematic content analysis about a theoretical-practical discipline we show elements that approach the integrative curricular paradigm, according to the theoretical references of Gimeno Sacristán, James Beane and Luíza Alonso. Indicators like contextualization of practice, integration of curricular areas and teacher integration are some of the elements that make up an integrated conception of curriculum, whose interdisciplinary in coherence with the central axis of curriculum development (health necessities of persons and populations identified by the health system) are pointed out in the Curricular Guidelines National for Medicine Courses as a possibility to develop meaningful and contextualized learning, focusing on the student as a subject of learning. These recommendations are of fundamental importance in the area of health, when the articulation of what one learns with the scenarios and the professional practices base (or at least must substantiate) the formation. The analysis made it possible to understand how health education can benefit from an integrated curricular organization that offers diversification and dialogue between different knowledge, relevant in the investigation and resolution of problems in the health-disease process, as well as the construction of theoretical-practical knowledge pertinent to a humanistic, critical and reflexive formation.
