title: Teaching History in the Base Nacional Comum Curricular: the historian attitude becoming competences

description: ABSTRACT Current curricular policies have presented narratives that project a professional profile aimed at the “new” teacher model. In this process, the meanings of teaching have been fixed through the centrality that some signifiers took in the curricula structuring for Basic Education and teacher training. In this article, we observe that the signifier historian attitude, a central element in the discourse, focused on the History component present in the Base Nacional Comum Curricular (BNCC) [National Common Curricular Base], when being juxtaposed to the signifier competence, present in the Base Nacional Comum de Formação de Professores (BNC-FP) [National Teacher Training Base], incorporates meanings based on neo-technical pedagogy, in translation and recontextualization processes that are underpinning a hybrid character. Our analysis was grounded on the understanding of the curriculum in cultural practice terms, which involves describing the curriculum as culture, as a place of enunciation, in opposition to a vision of a prescribed and privileged curriculum from a linear power conception. We observe that, since History teaching has been devoid of its fundamental relationship with historical knowledge, there is a need to set up undergraduate courses limited to training teachers to teach history. This is because there is teaching into a technique transformation process that prioritizes the learning to do in the curriculum structuring. In our view, this deprives teaching of its formative and political dimension and the initial training in the domain of the fundamentals of Science History and its ways of producing knowledge.

title: The effect of melatonin on in vitro maturation fertilization and early embryo development of mouse oocytes and expression of HMGB1 gene in blastocysts

description: Antioxidants are commonly used for maturation, fertilization and early development of embryos. Melatonin as an antioxidant have been recently proven to be useful for the assisted reproductive technology. In the present study, we evaluated the roles of melatonin in the in vitro maturation, fertilization, development and also the gene expression of high mobility group box-1 (HMGB1) in the blastocysts. The immature oocytes of BDF1 mice were transferred to the media containing different doses of melatonin (10-6, 10-9, 10-12 M). The blastocysts that developed under in vitro fertilization from each group were stained to determine the cell number of embryos and analyzed to determine the expression level of HMGB1 by real-time PCR. The most effective doses of melatonin for maturation of oocytes were 10-6 and 10-12M (P&lt;0.05). Fertilization rate, early development and the cell number of blastocysts were significantly higher in the group that treated with 10-12 M of melatonin comparing to the other groups. The HMGB1 expression decreased in groups that treated with 10-6M and 10-9M of melatonin and increased in the group that treated with 10-12 M of melatonin, but did not show a significant difference (p˃0.05). From the results, it may be concluded that the melatonin could be effective when the embryos undergo maturation, fertilization and early developmental processes. The HMGB1 expression, as a marker of early development in mice embryos, increased in the groups that treated with low doses of melatonin

title: Attractiveness of the facial profile: comparison of Class II patients treated with Twin Force® or intermaxillary elastics

description: ABSTRACT Objective: To compare the facial profile attractiveness of Class II patients treated with Twin Force® or intermaxillary elastics. Methods: Sample comprised 47 Class II patients divided into two groups: G1) TWIN FORCE - 25 patients treated with fixed appliances and Twin Force® fixed functional appliance (mean initial age was 17.91 ± 7.13 years, mean final age was 20.45 ± 7.18 years, and mean treatment time was 2.53 ± 0.83 years); G2) ELASTICS - 22 patients treated with fixed appliances and Class II intermaxillary elastics (mean initial age was 15.87 ± 5.64 years, mean final age was 18.63 ± 5.79 years and mean treatment time was 2.75 ± 0.60 years). Lateral cephalograms from pretreatment and posttreatment were used. Cephalometric variables were measured and silhouettes of facial profile were constructed and evaluated by 48 laypeople and 63 orthodontists, rating the attractiveness from 0 (most unattractive profile) to 10 (most attractive profile). Intergroup comparisons were performed with Mann-Whitney and independent t-tests. Results: At pretreatment, facial profile of the Twin Force® group was less attractive than the Elastics group. Treatment with Twin Force® or Class II elastics resulted in similar facial profile attractiveness, but the facial convexity was more reduced in the Twin Force® group. Orthodontists were more critical than laypeople. Conclusions: Treatment with Twin Force® or Class II elastics produced similar facial profile attractiveness at posttreatment. Profile attractiveness was reduced with treatment in the elastic group, and improved in the Twin Force® group. Facial convexity was more reduced with treatment in the Twin Force® group.

title: The Brazilian LGBT+ Health Survey: methodology and descriptive results

description: The understanding of health care demands and possible access barriers may support policymaking and best practices targeting the lesbian, gay, bisexual, transgender, and related identities (LGBT+) population. The aims of the Brazilian LGBT+ Health Survey were to characterize the LGBT+ population during the COVID-19 pandemic and to specify the characteristics of the COVID-19 pandemic in this population. This is a cross-sectional online study, with a convenience sample of 976 individuals identified as LGBT+, aged 18 years or older from Brazil. It allows investigations of sexuality, discrimination, internal homophobia, health-related behaviors, and health care access. The study adopts a conceptual framework (i.e., validated tools and measures) common to other epidemiological studies, allowing comparisons. We describe the study methodology, some descriptive results, and health-selected indicators compared with the Brazilian National Health Survey. Most of the respondents were from Southeast Region (80.2%), mean aged 31.3 (± 11.5 years). Regarding COVID-19, 4.8% tested positive. Both weekly episodes of discrimination (36%) and depression prevalence (24.8%) were high among the LGBT+ population in Brazil, highlighting mental health and homophobia as major concerns in the LGBT+ context during the pandemic. Although a decade has passed since the institution of the Brazilian National Policy for Comprehensive LGBT Health, appropriate training of health professionals to offer adequate services is still needed. Knowledge of the specific health demands of this group might guide person-centered best practices, promote sexual minority high-acceptance settings, and contribute to higher equity during the pandemic.

title: Work-related factors in the etiology of symptoms of post-traumatic stress among first responders: the Brazilian Firefighters Longitudinal Health Study (FLoHS)

description: Abstract: Two important aspects must be accounted for when discussing the mental health of first responders and, in particular, their report of post-traumatic stress symptoms (PTSS). The first concerns the provision of quantitative data from longitudinal study designs, the second concerns the sophistication of the work-related model used to frame such studies. This is a report on the development of a model for Brazilian firefighters who also work as first responders, from the establishment of a longitudinal panel design study, the Brazilian Firefighter Longitudinal Health Study (FLoHS). The first objective was to compare trainee and active firefighters based on their follow-up data with a nationwide sample of similarly aged Brazilians. The second was to test the effect that operational and organizational experiences had on firefighters’ PTSS level during follow up. At baseline, trainee firefighters came from higher socioeconomic backgrounds, were healthier and less exposed to trauma compared to a similarly aged national sample. At follow up, they reported higher prevalence of smoking, sleep problems, anhedonia and were more likely to be overweight. PTSS was predicted by operational and organizational stressors, even when controlled for health status at baseline. The results present not only the differences in the predictive status of operational and organizational events in relation to PTSS, but also how the effects of such events might interact. The data suggest the need for evidence-based interventions, support provided and changes at work environments to improve report rates for mental health in general and for PTSS in particular.

title: Three-dimensional pharyngeal airway space changes after bimaxillary advancement

description: ABSTRACT Introduction: The probability of improvement in the upper airway space (UAS) with orthognathic surgery should be considered during the surgical-orthodontic treatment decision, providing not only an esthetic, but also a functional benefit for the patient. Objective: The purpose of this study was to evaluate the 3D changes in the upper airway space after maxillomandibular advancement surgery (MMA). Methods: A retrospective analysis of 56 patients, 21 male and 35 female, with a mean age of 35.8 ± 10.7 years, who underwent MMA was performed. Pre- and postoperative cone-beam computed tomography scans (CBCT) were obtained for each patient, and the changes in the UAS were compared using Dolphin Imaging 11.7 software. Two parameters of the pharyngeal airway space (PAS) were measured: airway volume (AV) and minimum axial area (MAA). Paired t-test was used to compare the data between T0 and T1, at 5% significance level. Results: There was a statistically significant increase in the UAS. Bimaxillary advancement surgery increased the AV and the MAA, on average, by 73.6 ± 74.75% and 113.5 ± 123.87%, respectively. Conclusion: MMA surgery tends to cause significant increase in the UAS; however, this increase is largely variable.

title: Mortality and causes of deaths in prisons in Rio de Janeiro, Brazil

description: Abstract: Mortality in prisons, a basic indicator of the right to health for incarcerated persons, has never been studied extensively in Brazil. An assessment of all-cause and cause-specific mortality in prison inmates was conducted in 2016-2017 in the state of Rio de Janeiro, based on data from the Mortality Information System and Prison Administration. Mortality rates were compared between prison population and general population after standardization. The leading causes of death in inmates were infectious diseases (30%), cardiovascular diseases (22%), and external causes (12%). Infectious causes featured HIV/AIDS (43%) and TB (52%, considering all deaths with mention of TB). Only 0.7% of inmates who died had access to extramural health services. All-cause mortality rate was higher among prison inmates than in the state’s general population. Among inmates, mortality from infectious diseases was 5 times higher, from TB 15 times higher, and from endocrine diseases (especially diabetes) and cardiovascular diseases 1.5 and 1.3 times higher, respectively, while deaths from external causes were less frequent in prison inmates. The study revealed important potentially avoidable excess deaths in prisons, reflecting lack of care and exclusion of this population from the Brazilian Unified National Health System. This further highlights the need for a precise and sustainable real-time monitoring system for deaths, in addition to restructuring of the prison staff through implementation of the Brazilian National Policy for Comprehensive Healthcare for Persons Deprived of Freedom in the Prison System in order for inmates to fully access their constitutional right to health with the same quality and timeliness as the general population.
