Prevalence of symptoms of temporomandibular disorders, oral behaviors, anxiety, and depression in Dentistry students during the period of social isolation due to COVID-19
Temporomandibular dysfunction (TMD), anxiety, and depression are disorders that, due to the current lifestyle, are affecting an increasing portion of the population. Investigating the prevalence of the symptoms of these disorders during the quarantine due to the coronavirus 2019 pandemic (COVID-19) is important to outline clinical strategies for patient care. Objective: This study assessed the prevalence of TMD symptoms, anxiety, depression, and oral behaviors and their associations during the social isolation due to COVID-19. Methodology: Questionnaires were used to assess TMD symptoms in accordance with the Diagnostic Criteria for Temporomandibular Disorders: clinical protocol and assessment instruments, a questionnaire to verify oral behaviors and Hospital Anxiety and Depression Scale to assess symptoms of anxiety and depression in students of dentistry at the Faculty of Health Sciences of the University of Brasília in May 2020. Qualitative data were subjected to descriptive statistics and chi-squared analysis (p<0.05). The relationship between quantitative and qualitative data was evaluated using Spearman's rho correlation (p<0.05). Results: There was a high prevalence of TMD symptoms, anxiety, and depression in the participants, resulting in association between gender and anxiety symptoms (p=0.029). There was a positive correlation between oral behaviors and TMD symptoms (r=0.364; p<0.001), between oral behaviors and anxiety symptoms (r=0.312; p=0.001), and between oral behaviors and symptoms of depression (r=0.216; p=0.021). Conclusion: Social isolation due to the COVID-19 pandemic has an impact on the prevalence of TMD symptoms, anxiety, and depression

Gravidez na adolescência: perfil sociodemográfico de adolescentes grávidas no período de 2015 até 2019
Objective: to analyze the sociodemographic profile of pregnant adolescents in Brazil between 2015 and 2019. Method: descriptive cross-sectional study, with a quantitative approach, coming from the Information Technology Department of the Unified Health System. Data analysis used absolute and relative frequencies (%). Results: 2,405,248 pregnant adolescents were registered. The majority of pregnancies occurred in girls aged 15 to 19 years (95.2%), of a brown color (65.4%), single (64.9%), with 8 to 11 years of maternal education (66.9%). As for the characteristics of pregnancy, 98.7% were single pregnancy, lasting 37 to 41 weeks (81.7%) and vaginal type of delivery (61.2%). The temporal analysis showed a drop from 2015 to 2019. Conclusion: teenage pregnancy is a complex event in which attention must address a biopsychosocial context. Thus, delineating the sociodemographic profile of these adolescents is necessary, as it makes it possible to get to know the population under study and its vulnerability conditions.Objetivo: analizar el perfil sociodemográfico de las adolescentes embarazadas en Brasil entre los años 2015 y 2019.

SEXUALIDADE E GÊNERO NA EDUCAÇÃO: CONTEXTO ESCOLAR EM MACEIÓ E A ADAPTAÇÃO ÀS NOVAS DEMANDAS
Está cada vez mais frequente a discussão sobre sexualidade e gênero na educação. Variados setores da sociedade manifestam-se tanto a favor como contra as mudanças nos planos de ensino. O presente trabalho objetiva pensar em uma escola menos favorável a reprodução e perpetuação de violências, identificar os obstáculos que dificultam a promoção dos direitos humanos nas escolas e reforçar como as questões de gênero e sexualidade se faz de extrema importância para uma educação que garanta vivências positivas com as diferenças. O trabalho foi feito em duas partes: 1) uma revisão literatura, onde buscamos em artigos, livros e jornais eletrônicos dados para confortar ideias, 2) e uma pesquisa de campo onde foram feitas quatro entrevistas sendo duas em escolas particulares e duas em escola pública da rede estadual, Os dados nos mostraram que a dinâmica das relações de poder e as dinâmicas de legitimação e deslegitimação presentes no ambiente escolar precisam ser problematizadas; a Psicologia não pode se ausentar do ambiente escolar a fim de atuações inovadoras; a formação profissional necessita se adequar as demandas contemporâneas e as necessidades vigentes da sociedade
The genome sequence of Pseudoplusia includens single nucleopolyhedrovirus and an analysis of p26 gene evolution in the baculoviruses
Background: Pseudoplusia includens single nucleopolyhedrovirus (PsinSNPV-IE) is a baculovirus recently identified in our laboratory, with high pathogenicity to the soybean looper, Chrysodeixis includens (Lepidoptera: Noctuidae) (Walker, 1858). In Brazil, the C. includens caterpillar is an emerging pest and has caused significant losses in soybean and cotton crops. The PsinSNPV genome was determined and the phylogeny of the p26 gene within the family Baculoviridae was investigated. Results: The complete genome of PsinSNPV was sequenced (Roche 454 GS FLX – Titanium platform), annotated and compared with other Alphabaculoviruses, displaying a genome apparently different from other baculoviruses so far sequenced. The circular double stranded DNA genome is 139,132 bp in length, with a GC content of 39.3 %
and contains 141 open reading frames (ORFs). PsinSNPV possesses the 37 conserved baculovirus core genes, 102 genes found in other baculoviruses and 2 unique ORFs. Two baculovirus repeat ORFs (bro) homologs, bro-a (Psin33) and bro-b (Psin69), were identified and compared with Chrysodeixis chalcites nucleopolyhedrovirus (ChchNPV) and Trichoplusia ni single nucleopolyhedrovirus (TnSNPV) bro genes and showed high similarity, suggesting that these genes may be derived from an ancestor common to these viruses. The homologous repeats (hrs) are absent from the PsinSNPV genome, which is also the case in ChchNPV and TnSNPV. Two p26 gene homologs (p26a and p26b) were found in the PsinSNPV genome. P26 is thought to be required for optimal virion occlusion in the occlusion bodies (OBs), but its function is not well characterized. The P26 phylogenetic tree suggests that this gene was obtained from three independent acquisition events within the Baculoviridae family. The presence of a signal peptide only in the PsinSNPV p26a/ORF-20 homolog indicates distinct function between the two P26 proteins. Conclusions: PsinSNPV has a genomic sequence apparently different from other baculoviruses sequenced so far. The complete genome sequence of PsinSNPV will provide a valuable resource, contributing to studies on its molecular biology and functional genomics, and will promote the development of this virus as an effective bioinsecticide
Tratamiento de caries relacionada a radiación: una revisión de literatura
Caries relacionada a radiación es una complicación tardı́a frecuente de la radioterapia de cáncer de cabeza y cuello, ocasionada por efectos directos e indirectos de la radioterapia. El objetivo del presente trabajo es realizar una revisión y analizar literatura sobre el manejo de caries relacionada a radiación, materiales usados, fallas en el tratamiento y protocolo con mejores resultados; tres revisores independientes realizaron una búsqueda en diferentes bases de datos: PubMed, Lilacs y Web Of Science, determinando criterios de inclusión y exclusión para la selección. Estudios clı́nicos y revisiones indicaron que los materiales más usados son cemento ionómero de vidrio convencional, cemento ionómero de vidrio modiicado con resina y resina compuesta con aplicaciones
de lúor. Son necesarios más estudios para definir el mejor tratamiento que incluya técnica de preparación de la cavidad y material restaurador con mejores resultados. Se recomienda realizar estudios comparando diferentes sistemas adhesivos, concentraciones de lúor y restauraciones en dentina radicular
Social Networks Shape the Transmission Dynamics of Hepatitis C Virus
Hepatitis C virus (HCV) infects 170 million people worldwide, and is a major public health problem in Brazil, where over 1% of the population may be infected and where multiple viral genotypes co-circulate. Chronically infected individuals are both the source of transmission to others and are at risk for HCV-related diseases, such as liver cancer and cirrhosis. Before the adoption of anti-HCV control measures in blood banks, this virus was mainly transmitted via blood transfusion. Today, needle sharing among injecting drug users is the most common form of HCV transmission. Of particular importance is that HCV prevalence is growing in non-risk groups. Since there is no vaccine against HCV, it is important to determine the factors that control viral transmission in order to develop more efficient control measures. However, despite the health costs associated with HCV, the factors that determine the spread of virus at the epidemiological scale are often poorly understood. Here, we sequenced partial NS5b gene sequences sampled from blood samples collected from 591 patients in São Paulo state, Brazil. We show that different viral genotypes entered São Paulo at different times, grew at different rates, and are associated with different age groups and risk behaviors. In particular, subtype 1b is older and grew more slowly than subtypes 1a and 3a, and is associated with multiple age classes. In contrast, subtypes 1a and 3b are associated with younger people infected more recently, possibly with higher rates of sexual transmission. The transmission dynamics of HCV in São Paulo therefore vary by subtype and are determined by a combination of age, risk exposure and underlying social network. We conclude that social factors may play a key role in determining the rate and pattern of HCV spread, and should influence future intervention policies
