This study aimed to examine the sociodemographic profile of sexual and gender minorities who regularly interact with children and investigate whether such frequent interactions are associated with healthcare factors. This cross-sectional study utilized data from the LGBT+ Health Survey in Brazil, conducted online and anonymously from August to November 2020 with 958 participants. Regular interaction with children was defined as living with children or engaging in bi-weekly face-to-face meetings with children residing in different households. Healthcare factors encompass having a professional or reference service, feeling comfortable in discussing personal issues, and receiving worse quality medical or hospital care. The statistical analysis used the Poisson regression with robust variance. The prevalence of interaction with children was 5.3%. We observed a statistically higher prevalence among cisgender women (13.4%) and Black/brown and other non-white people (7.9%) after adjusting for age. The results showed a positive association only between regular interaction with children and worse-quality medical or hospital care received (PR=6.00; 95%CI 1.22-29.67). These findings highlight a persistent stigma and prejudice within healthcare services. [ABSTRACT FROM AUTHOR]

Rabies is an invariably fatal infectious-contagious viral disease caused by viruses in the genus Lyssavirus, which affects the central nervous system of domestic and wild mammals. This study draw attention to the importance of insectivorous bats and domestic cats in the epidemiology of rabies. For this, two cases of rabies registered in domestic cats in the southeast region of Rio Grande do Sul were analyzed. Diagnoses were based on histological alterations and positive staining for the virus in direct immunofluorescence with confirmation by biological test, immunohistochemical evaluation and identification of the rabies virus variant by polymerase chain reaction. In Brazil, a change in the epidemiological profile of rabies has been observed, in which bats play a major role in the current chain of transmission of the disease. It is noteworthy, that the antigenic viral variant AgV-4, typical of the insectivorous bat Tadarida brasiliensis, was identified in the domestic cats affected in this study [ABSTRACT FROM AUTHOR]

Objective: to analyze association between sociodemographic factors and cardiovascular health risk behaviors of Brazilian adolescents aged 13-17 years., Methods: we used data on 10,926 adolescents from the 2015 National School-Based Health Survey (PeNSE) to verify associations between socio-demographic variables and consumption of unhealthy foods, insufficient physical activity, and experimentation with alcoholic beverages and cigarettes, using Poisson regression., Results: associations were found between consumption of candies, insufficient physical activity and experimentation with alcoholic beverages and the female sex ([PRa=1.37 - 95%CI 1.25;1.50], [PRa=1.32 - 95%CI 1.26;1.38] and [PRa=1.05 - 95%CI 1.00;1.10]); soda consumption with the male sex (PRa=1.17 - 95%CI 1.03;1.31) and higher maternal schooling (PRa=1.14 - 95%CI 1.01;1.31); cigarette experimentation with the male sex (PRa=1.12 - 95%CI 1.00;1.25), being 16-17 years old (PRa=1.51 - 95%CI 1.33;1.72), not living with father (PRa=1.36 - 95%CI 1.20;1.53) or mother (PRa=1.25 - 95%CI 1.13;1.37)., Conclusion: cardiovascular health risk behaviors influenced by sociodemographic characteristics should be taken into consideration in Brazilian adolescent health promotion.

Histoplasma capsulatum is a dimorphic fungal pathogen naturally found in the soil. Inhalation of conidia can result in pulmonary histoplasmosis and, in some cases, causes severe disseminated disease and death. This fungus is an ascomycete that has an anamorphic or asexual stage and a teleomorphic or sexual stage, known as Ajellomyces capsulatus, which results from (+) and (-) mating types. Sexual reproduction is regulated by a specialized genomic region known as the mating-type (MAT1) locus. The mating process in this heterothallic species is represented by isolates that contain only one of the two different MAT1 locus idiomorphs (MAT1-1 or MAT1-2) that have unrelated sequences encoding different transcription factors. In medically important dimorphic pathogens and in most ascomycete molds, one MAT locus idiomorph encodes a high-mobility-group (HMG) box-domain transcription factor, and the other idiomorph encodes an alpha-box domain transcription factor. There is scarce molecular information about H. capsulatum mating type although recombinant population structures have been reported that could occur in nature and this process has been documented in distinct models such as parasites and other fungi. In this review, we shall focus on published studies on H. capsulatum sexuality, and outline the distribution of the two H. capsulatum mating types in Latin America. This manuscript is part of the series of works presented at the "V International Workshop: Molecular genetic approaches to the study of human pathogenic fungi" (Oaxaca, Mexico, 2012)., (Copyright © 2013 Revista Iberoamericana de Micología.

This article seeks to evaluate the growth of children attending public day care centers of the Government of the State of Paraiba and the relative significance of vitamin A, iron and zinc deficiencies. It involved a cross-sectional study of 240 preschool children. The following categories of nutritional status were considered: underweight (W/H < -2 z-scores), stunting (H/A < -2 z-scores) and overweight (W/H > +2 z-scores). Serum concentrations of retinol, zinc and hemoglobin were established to assess vitamin A deficiency (< 0.70 mmol/L), zinc deficiency (< 65 mmol/L) and anemia (< 110 g/L), respectively. The prevalence of stunting was 5.8%, that of overweight 3.8%, and that of underweight 0.4%. W/H z-scores were lower and statistically significant in children aged 12-36 months. An association was also found between W/H z-scores and maternal height. This association was also observed regarding body mass index. H/A z-scores were lower and statistically significant in low birth weight children. Lower hemoglobin concentrations were detected in children aged 12-36 months who were not receiving the financial support of the Bolsa Familia (Family Allowance) program. There was no significant association between vitamin A, iron and zinc deficiencies and the anthropometric indices studied.

The MAT1-1 and MAT1-2 idiomorphs associated with the MAT1 locus of Histoplasma capsulatum were identified by PCR. A total of 28 fungal isolates, 6 isolates from human clinical samples and 22 isolates from environmental (infected bat and contaminated soil) samples, were studied. Among the 14 isolates from Mexico, 71.4% (95% confidence interval [95% CI], 48.3% to 94.5%) were of the MAT1-2 genotype, whereas 100% of the isolates from Brazil were of the MAT1-1 genotype. Each MAT1 idiomorphic region was sequenced and aligned, using the sequences of the G-217B (+ mating type) and G-186AR (- mating type) strains as references. BLASTn analyses of the MAT1-1 and MAT1-2 sequences studied correlated with their respective + and - mating type genotypes. Trees were generated by the maximum likelihood (ML) method to search for similarity among isolates of each MAT1 idiomorph. All MAT1-1 isolates originated from Brazilian bats formed a well-defined group; three isolates from Mexico, the G-217B strain, and a subgroup encompassing all soil-derived isolates and two clinical isolates from Brazil formed a second group; last, one isolate (EH-696P) from a migratory bat captured in Mexico formed a third group of the MAT1-1 genotype. The MAT1-2 idiomorph formed two groups, one of which included two H. capsulatum isolates from infected bats that were closely related to the G-186AR strain. The other group was formed by two human isolates and six isolates from infected bats. Concatenated ML trees, with internal transcribed spacer 1 (ITS1) -5.8S-ITS2 and MAT1-1 or MAT1-2 sequences, support the relatedness of MAT1-1 or MAT1-2 isolates. H. capsulatum mating types were associated with the geographical origin of the isolates, and all isolates from Brazil correlated with their environmental sources.
