title: Stigma and discrimination related to gender identity and vulnerability to HIV/AIDS among transgender women: a systematic review

description: Abstract: HIV prevalence among transgender women is disproportional when compared to the general population in various countries. Stigma and discrimination based on gender identity have frequently been associated with vulnerability to HIV/AIDS. The objective was to conduct a systematic literature review to analyze the relationship between stigma and discrimination related to gender identity in transgender women and vulnerability to HIV/AIDS. This systematic literature review involved the stages of identification, compilation, analysis, and interpretation of results of studies found in five databases: PubMed, Scopus, Web of Science, Science Direct, and LILACS. No publication time period was determined in advance for this review. The studies were assessed according to the inclusion and exclusion criteria. The review included articles in English, Portuguese, or Spanish that related stigma and discrimination to transgender women’s vulnerability to HIV. We found 41 studies, mostly qualitative, published from 2004 to 2018, and categorized in three dimensions of stigma: individual, interpersonal, and structural. The data highlighted that the effects of stigma related to gender identity, such as violence, discrimination, and transphobia, are structuring elements in transgender women’s vulnerability to HIV/AIDS. The studies showed a relationship between stigma and discrimination and transgender women’s vulnerability to HIV/AIDS and indicated the need for public policies to fight discrimination in society.

title: Body construction and health itineraries: a survey among travestis and trans people in Rio de Janeiro, Brazil

description: The article examines health itineraries followed by Brazilian travestis, trans men and trans women in the affirmation of their gender, based on the survey Trans Uerj: Health and Citizenship of Trans People in Brazil. The survey’s main objectives were to gauge the trans/travesti population’s diversity and sociodemographic profile; and to map the various ways they access their rights as citizens, especially to healthcare services and body modification technologies. Interviewers, mainly trans people and travestis, applied 391 questionnaires in the city of Rio de Janeiro and its metropolitan region to interviewees of different social classes, schooling levels and gender identity configurations, contacted through the interviewers’ social networks. For defining respondents’ gender identities the survey used an original method based on self-definitions, which were then aggregated into 6 categories for data analysis purposes. This article discusses the multiple strategies used by this trans population in gender affirmation processes to gain access to regulated and/or unregulated use of hormones and surgical procedures.

title: Isolation of entomopathogenic nematodes in an apple orchard in Southern Brazil and its virulence to Anastrepha fraterculus (Diptera: Tephritidae) larvae, under laboratory conditions

description: Abstract Entomopathogenic nematodes (EPNs) are a promising alternative to integrated control in many fruit pests. Few studies were made on the relationship of Anastrepha fraterculus natural population with native EPNs population and other biotic and abiotic factors. The aim of this work was to verify the occurrence of endemic nematodes in an apple orchard, concerning environmental conditions and technical procedure, and access isolates virulence to A. fraterculus larvae. The experiment was conducted during a year taking monthly soil samples from an apple orchard, with and without fallen fruits just above the soil. Samples were baited with Tenebrium molitor and A. fraterculus larvae in laboratory. Canopy and fallen fruits were sampled to access the pest infestation. Seventy three EPN isolates were captured, in 23.2% soil samples, more with T. molitor than with A. fraterculus baits. From the 20 isolates tested against A. fraterculus, only five were pathogenic, and they were identified as Oscheius sp. The nematodes were captured during all seasons in a similar frequency. Soil and weather conditions, presence of fruit over the orchard soil, and A. fraterculus pupae in the fruits had no significant influence on the capture. As a conclusion, nematodes of the genera Oscheius are found in an apple orchard of Porto Amazonas constantly along the year, independently of fluctuations in A. fraterculus population, climate conditions and presence of fruit over the soil. Some of the isolates are pathogenic to A. fraterculus.

title: Quality of life of children with poor school performance: association with hearing abilities and behavioral issues

description: ABSTRACT The aim of the present study was to investigate the quality of life of children with poor school performance and its association with behavioral aspects and hearing abilities. Methods: This cross-sectional observational study, developed in a town in the state of Minas Gerais, Brazil, investigated a random sample of public school children, aged 7-12 years old, who performed poorly in school and received specialized educational assistance. The study comprised two stages: 1) collection of data from parents on their children's health, educational, and socioeconomic profile, and from the Strengths and Difficulties Questionnaire; 2) administration of a quality of life evaluation scale to the schoolchildren. For the assessment of auditory function, transient otoacoustic emissions were used and auditory processing was tested. The following tests were used: verbal sequential memory, nonverbal sequential memory, sound localization, dichotic digits, duration pattern test (flute) and random gap detection. The collected data were analyzed using Excel and STATA 11.0 software. Quality of life was considered the response variable. The explanatory variables were grouped for univariate and multivariate logistic regression analysis with the level of significance set at 5%. Results: A statistically significant association was found between impaired quality of life, altered pro-social behavior, and the absence of parental complaints about the children's written language development. Conclusions: Quality of life is impaired in children with poor school performance. The lack of parental complaints about written language and changes in social behavior increased the likelihood of a child having a poor quality of life.

title: Influence of Phenology and Post-Harvest Processing of Vegetal Material on the Allelopathy of Annoni Grass (Eragrostis plana) Extracts

description: ABSTRACT: The phenological stage, post-harvest processing and quantity of material can interfere in the allelopathic activity of extracts. The objective of this study is to test the allelopathic effect of aqueous extracts of the leaves of Annoni grass (Eragrostis plana), an invader of natural pastures. Twelve extracts were prepared by combining the phenological stage of the plants when harvesting the leaves (vegetative; flowering), post-harvest processing before extraction (fresh; dry at 40 oC), and the amount of plant material (5, 15, and 25 g 100 mL-1 distilled water). Two bioassays were conducted in a germination chamber, with evaluation of germination and growth of seedlings of lettuce (Lactuca sativa) and white clover (Trifolium repens). The extracts with higher allelopathic activity were further developed with 15 and 25 g of dried leaves and harvested in plants at the vegetative stage. Germination was attributed to being the greatest contribution to the divergence between the extracts. White clover was more sensitive to extracts, for which 50% to 67% of the extracts were effectively allelopathic (≥50% inhibition); in lettuce, between 8% and 58% of the extracts exhibited this potential. The phenological stage was the factor with a greater individual effect on the allelopathic activity on lettuce and white clover seedlings, and on lettuce germination. The post-harvest processing responded by the greater variation on germination and germination speed index of white clover. The sensitivity of the white clover to extracts of Annoni grass suggests a compromise of its establishment in pastures with the presence of the invader.

title: Quality of fresh and cryopreserved semen and their influence on the rates of fertilization, hatching and quality of the larvae of Piaractus mesopotamicus

description: Abstract In this work, the seminal parameters of P. mesopotamicus were evaluated fresh and after cryopreservation, focusing on the sperm variables that affect the rates of fertilization, hatching and post-hatching parameters such as larval survival and morphology. The semen and oocytes from the animals were collected after extrusion, and seminal quality and oocyte fertilization were analyzed. Subsequently, a portion of each semen sample was cryopreserved and, after two days, the oocytes from three new females were fertilized with cryopreserved semen from the males. The analyzes showed that progressive motility, spermatic vigor, motility duration, number of normal sperm and secondary abnormalities were higher in fresh semen than in semen after thawing (P &lt;0.0001). Similarly, fertilization and hatching rates and the percentage of normal and abnormal larvae in fertilized oocytes were higher when fresh semen was used (P &lt;0.0001). The cryopreservation process affected the qualitative parameters of the semen of Piaractus mesopotamicus. The primary abnormality of spermatozoa was the main variable that influenced both fertilization and hatching rates, both in fresh and thawed semen. The second most important variable that influenced, particularly, thawed semen, was the spermatic vigor.

title: The Olympic Experimental Gymnasium Program and its Association with the Prevalence of Cardiovascular Risk Factors in Adolescents: A Cross-Sectional Study

description: Abstract Background: Cardiovascular disease (CVD) is the leading cause of death worldwide. Physical activity (PA) and appropriate diet, if adopted in childhood and adolescence, may reduce the CVD burden in later life. The Olympic Experimental Gymnasium (OEG) project was implemented to increase the PA levels of students by means of regular physical exercise and healthy eating habits. Objectives: To estimate and compare the prevalence of CVD risk factors in OEG schools versus regular schools (RSch) and to examine associations between the school environment and CVD risk factors. Methods: In this cross-sectional study with a comparator group, adolescents aged 12-13 years attending three OEG schools (n = 719) and three RSch (n = 394) were evaluated after one year of the ongoing program to estimate the prevalence of overweight, pre-hypertension/hypertension, altered glycemia, and lipid profile. An α level of 0.05 was set for statistical analysis. Results: RSch students had higher odds to have high blood pressure (OR 1.86, 1.36-2.54) and to be overweight (OR 1.49, 1.13-1.98) than OEG students. Glucose levels were not altered in most cases regardless of school type, and no differences were found in lipid profile. In the sensitivity analysis stratified by gender, girls from RSch were more likely to have high body mass index than boys. Conclusions: Exposure of adolescents to the OEG policies was positively associated with an important reduction in CVD risk factors, including high blood pressure and overweight.

title: Analysis of the virtual water flow: an approach based on the trade balance of Mato Grosso do Sul

description: Abstract: The allocation of water resources has attracted the attention of the most diverse segments of modern society. Generally, in regions characterized by agriculture, such as the state of Mato Grosso do Sul (MS), the use of water in the production process becomes more intensive, so as to reflect on the use of natural resources. The idea of "virtual water" is based on the concept of water embedded in the products, and has attracted growing interest from the national and international community in view of the need to improve the management of water resources. Therefore, the main objective of this article is to analyze the balance of virtual water resulting from the international trade of the South-Mato Grosso State and the rest of the world in order to verify the surplus or deficit balance in relation to its main products marketed abroad. In order to verify if the virtual water balance is favorable or unfavorable to the State, one should measure the exchange ratios in the product-to-product trade using the methodology of the calculation of the Water Footprint proposed by Hoekstra et al. (2011) as well as the backward and forward chaining indicators defined by the input-output matrix in order to understand the behavior of water demand in the state economy. The results point to a deficit in the balance of water transactions between this State and the other economies with which it markets its products.

title: Chemical composition of essential oils from the apiaceae family, cytotoxicity, and their antifungal activity in vitro against candida species from oral cavity

description: Abstract The aims of this research were: evaluate the chemical composition and the cytotoxicity of the Cuminum cyminum (cumin), Anethum graveolens (dill), Pimpinella anisum (anise) and Foeniculum vulgare (fennel) essential oils, as well as their antifungal activity in vitro against ten Candida spp. isolates. The chemical composition of the oils was analyzed by means of gas chromatography coupled with mass spectrometry (GC/MS). The cytotoxicity assays were performed, using the cell proliferation reagent WST-1 in L929 mouse fibroblasts (20x103 well-1). The determinate the Minimum Inhibitory Concentration (MIC), was performed through the Broth Microdilution technique (CLSI). The chemical main components were the cuminaldehyde (32.66%) for cumin, carvone (34.89%) for the dill, trans-anethole (94.01%) for the anise and anethole (79.62%) for the fennel. Anise and fennel did not were cytotoxic in all the tested concentrations, however the cumin oil was cytotoxic in the concentration of 20 mg.mL-1 and the dill in the concentrations of 20 and 8 mg.mL-1. All yeasts were susceptible against the evaluated essential oils. Cumin presented the lowest MIC against yeasts. We concluded that all the essential oils presented inhibitory action against Candida spp., and C . cyminum, P. anisum and F. vulgare were not cytotoxic in the same minimum inhibitory concentrations for the fungi.

title: Correlation Between Volume of Root Canal, Cultivable Bacteria, Bacterial Complexes and Endotoxins in Primary Infection

description: Abstract This clinical study was conducted to correlate the levels of endotoxins and culturable bacteria found in primary endodontic infection (PEI) with the volume of root canal determined by using Cone Beam Computed Tomography (CBCT); and to evaluate the bacterial diversity correlating with clinical features. Twenty patients with PEI were selected and clinical features were recorded. The volume (mm3) of root canal was determined by CBCT analysis. Root canal samples were analyzed by using kinetic LAL-assay test to determine the levels of endotoxins and anaerobic technique to determine the bacterial count (CFU/mL). DNA was extracted from all samples to determine bacterial diversity and quantified by using Checkerboard-DNA-DNA- Hybridization. Culturable bacteria and endotoxins were detected in 100% of the root canal samples. Linear regression analysis revealed a correlation between root canal volume and presence of anaerobic bacteria (p&lt;0.05). Positive correlations were found between bacteria species and presence of different clinical features (p&lt;0.05). After grouping the bacteria species into bacterial complexes, positive associations were found between green, orange and red complexes with presence of sinus tract (p&lt;0.05). This clinical study revealed that larger root canals hold higher levels of culturable bacteria in PEI. Thus, the interaction of different virulent bacteria species in complexes seems to play an important role in the development of clinical features.
