Prevalence of intestinal parasites among inmates in Midwest Brazil.
2017
Made available in DSpace on 2018-11-26T17:40:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-09-21 Fundacao de Desenvolvimento, Ensino, Ciencia e Tecnologia do Estado de Mato Grosso do Sul (FUNDECT) Background Intestinal parasitic infections constitute a public health issue in developing countries, with prevalence rates as high as 90%, a figure set to escalate as the socioeconomic status of affected populations deteriorates. Investigating the occurrence of these infections among inmates is critical, since this group is more vulnerable to the spread of a number of infectious illnesses. Methods This cross-sectional, analytical, quantitative study was conducted in July 2015 at prison…
Can bayesian models play a role in dental caries epidemiology? Evidence from an application to the BELCAP data set
2012
Objectives The aim of this study was to show the potential of Bayesian analysis in statistical modelling of dental caries data. Because of the bounded nature of the dmft (DMFT) index, zero-inflated binomial (ZIB) and beta-binomial (ZIBB) models were considered. The effects of incorporating prior information available about the parameters of models were also shown. Methods The data set used in this study was the Belo Horizonte Caries Prevention (BELCAP) study (Bohning et al. (1999)), consisting of five variables collected among 797 Brazilian school children designed to evaluate four programmes for reducing caries. Only the eight primary molar teeth were considered in the data set. A data aug…
CBCT location of the fusion between the buccal and lingual cortical in the mandibular ramus : importance to sagittal split osteotomy
2016
Background Mandibular Sagittal Split Osteotomy (MSSO) is a popular technique in orthognathic surgery used both to advance and to retreat the mandible. However, MSSO may incur in important complications, such as bad splits and sensorineural injuries. Knowing the location of the fusion between the buccal and lingual cortical (FBLC) in the mandibular ramus and the bone thickness in the region where osteotomies will be performed is determinant in MSSO planning to avoid complications. The aim of this study was to document and evaluate possible differences between sexes regarding the location of the FBLC in relation to the superior cortical of mandibular foramen (MF) and bone thickness in the reg…
Três performances para um país que luta com arte
2020
Durante o “II Seminário Internacional de Arte / Gênero / Ensino em Tempos de Conservadorismo”, realizado no Centro de Artes da Universidade Regional do Cariri - URCA (Crato, Brasil), pudemos assistir e participar de várias performances artísticas, atividade que dava início a cada dia do Seminário. Apresentamos aqui um ensaio visual baseado em três performances nas quais os artistas interagiram com as pessoas no espaço público: Tálamo, de Maria Macêdo (13/08/2019, 20:30, Plaza Cristo Rei, Crato); Bagagem, de Shambuyi Wetu, artista da República Democrática do Congo que vive atualmente em São Paulo, Brasil (15/08/2019, 8:30 da manhã, Praça Cristo Rei, Crato); e Super Zentai, de Rafael Bqueer, …
In vitro leishmanicidal activity of pyrazole-containing polyamine macrocycles which inhibit the Fe-SOD enzyme of Leishmania infantum and Leishmania b…
2014
The in vitro leishmanicidal activity and cytotoxicity of pyrazole-containing macrocyclic polyamines 1-4 was assayed on Leishmania infantum and Leishmania braziliensis species. Compounds 1-4 were more active and less toxic than glucantime and both infection rates and ultrastructural alterations confirmed that 1 and 2 were highly leishmanicidal and induced extensive parasite cell damage. Modifications in the excretion products of parasites treated with 1-3 were also consistent with substantial cytoplasm alterations. Compound 2 was highlighted as a potent inhibitor of Fe-SOD in both species, whereas its effect on human CuZn-SOD was poor. Molecular modelling suggested that 2 could deactivate Fe…
Efficacy and safety of neoadjuvant pertuzumab and trastuzumab in women with locally advanced, inflammatory, or early HER2-positive breast cancer (Neo…
2011
Summary Background Studies with pertuzumab, a novel anti-HER2 antibody, show improved efficacy when combined with the established HER2-directed antibody trastuzumab in breast cancer therapy. We investigated the combination of pertuzumab or trastuzumab, or both, with docetaxel and the combination of pertuzumab and trastuzumab without chemotherapy in the neoadjuvant setting. Methods In this multicentre, open-label, phase 2 study, treatment-naive women with HER2-positive breast cancer were randomly assigned (1:1:1:1) centrally and stratified by operable, locally advanced, and inflammatory breast cancer, and by hormone receptor expression to receive four neoadjuvant cycles of: trastuzumab (8 mg…
Relations of Metabolically Healthy and Unhealthy Obesity to Digital Vascular Function in Three Community‐Based Cohorts: A Meta‐Analysis
2017
Background Microvascular dysfunction is a marker of early vascular disease that predicts cardiovascular events. Whether metabolically healthy obese individuals have impaired microvascular function remains unclear. The aim of this study was to evaluate the relation of obesity phenotypes stratified by metabolic status to microvascular function. Methods and Results We meta‐analyzed aggregate data from 3 large cohorts (Brazilian Longitudinal Study of Adult Health, the Framingham Heart Study, and the Gutenberg Heart Study; n=16 830 participants, age range 19–90, 51.3% men). Regression slopes between cardiovascular risk factors and microvascular function, measured by peripheral arterial tonometr…
The taint of torture and the brazilian legal system
2019
In Brazil, the practice of torture intertwines deeply with its own history. The literature on the subject has had a greater intensification on its registers during the Dictatorial Regime (1964 to 1985). In spite of the Brazilian Constitution of 1988, Brazil only makes efforts to investigate the crimes of torture of this period to comply with the provisions of the United Nations in 2011. Within this scenario, the NationalTruth Commission (Law 12.528, of November 2011) was created with the purpose of clarifying the facts and circumstances of cases concerning human rights violations, as well as the Law on Access to Information (Law 12.527 of November 2011), which have regulated the constitutio…
Prevalence and characterization of maxillary sinus septa in a brazilian population
2019
Background The aim of this study was to assess the anatomic aspects of the maxillary sinus septa, by means of computed tomography images, in a Brazilian population. The results might be of clinical significance in sinus lift surgery planning. Material and methods In the study, 123 computed tomographs obtained from a private radiology clinic were used. They were analyzed by a single, trained and calibrated observer in order to evaluate the presence, quantity, localizations, dimensions, orientations and different characteristics in dentate, partially edentulous and completely edentulous individuals of the sinus septa. Results Of the individuals analyzed, 26% had a septum in the maxillary sinu…
Le parti des travailleurs brésilien : de son émergence à la conquête du Planalto (1979 - 2002)
2016
The Brazilian Workers’ Party (PT) is an outstanding experience of a left-wing mass party. When it was born in 1980, many people wondered about its nature. In 2002, when Lula became the President of Brazil, this question did not deserve the same answer. The PT became bureaucratic, institutional and professional, experiencing a sort of accelerated Social-Democratization. As its starting point, this study takes the specificities of labour movement, trade unionism and the dictatorship (1964-1985) in Brazil. The PT originated in 1979-80 from mass social struggles around “authentic” trade unionists (such as Lula), left-wing Catholics, far-left activists, the left-wing intelligentsia and some “pro…
