Abstract The iAtlantic Project has established an international collaborative strategy to improve mapping and characterization of deep and open ocean ecosystems in understudied regions of the Atlantic and evaluate their health. In December 2022, the first iAtlantic expedition in the South Atlantic set off to map and explore seafloor ecosystems in the Santos Basin slope (200-1,000 m depths) in collaboration with the Petrobras ‘Santos Basin - Regional Characterization Project.’ The 17-day ‘iAtlantic_BR10-Petrobras’ cruise was conducted on board the research vessel NPqHOc Vital de Oliveira (Brazilian Navy) and performed (a) water column structure characterization, (b) seafloor morphology mapping, (c) description of benthic habitats and communities by seafloor imagery and biological/ geological sampling, and (d) ex-situ experiments to assess the functioning of sedimentary ecosystems and their responses to climate-related environmental changes. This study describes the rationale behind the iAtlantic_BR10-Petrobras cruise science plan, reports its sampling strategy and methods, and summarizes its collected data and preliminary results.

ABSTRACT The garden fleahopper, Microtechnites bractatus (Say) (Hemiptera: Miridae), is associated with several cultivated plant species and, despite its economic importance, little is known about its development and performance in such hosts. We described here, the morphology of immature stages, and evaluated the biology of M. bractatus in beans, potatoes, white clover, alfalfa, and wheat. The bioassays were carried out in the laboratory under controlled temperature (25±2ºC), humidity (UR70±15%), and photoperiod (12L:12D). The eggs of M. bractatus are elongated and slightly curved, without respiratory projections and light yellow in color, becoming dark at the end of the incubation period. Nymphs present an oval-shaped body, a reddish color that intensifies along with the development and dimorphic wing pads in the fifth instar. In the bioassays, the host plants influenced the biological aspects of M. bractatus, both in the immature and adult stages. Nymph survival was higher in clover and alfalfa, while in wheat, it was lower. Clover-fed insects had the longest longevity. The fecundity parameters and egg viability were favored in insects that fed on clover and alfalfa. The fertility life table showed that feeding M. bractatus with clover provides a higher net reproduction rate (R0) and a higher finite ratio of population increase (ʎ). This study contributes to bioecological and behavioral studies on M. bractatus and provides data for the recognition and characterization of individuals in the immature stage.

RESUMO Objetivo: Associar a trajetória de vida de Dom Pedro II com o começo da história da psiquiatria brasileira por meio do Hospício Pedro II. Métodos: Realizamos uma revisão narrativa da literatura com a pesquisa de três bases de dados: Google Scholar, PubMed e Web of Science (SciELO). Resultados: A primeira instituição psiquiátrica brasileira, o Hospício Pedro II (1841-1889), foi criado por meio do Decreto nº 82, publicado no dia 18 de julho de 1841. Essa publicação ocorreu durante a cerimônia de coroação de Dom Pedro II. O objetivo dessa cerimônia de coroação era fortalecer o poder da monarquia brasileira e legitimizar a antecipação da maioridade do imperador com 14 anos. Ao longo dos 48 anos do império de Dom Pedro II, seus interesses culturais e científicos influenciaram o surgimento de uma incipiente pesquisa científica brasileira. Nesse sentido, o Hospício Pedro II não era apenas representativo de uma instituição de saúde, mas uma resposta às mudanças sociais e culturais que ocorreram após a chegada da família real portuguesa em 1808. Também era um representativo da influência da psiquiatria francesa baseada no tratamento moral de Phillipe Pinel (1745-1826). Conclusão: De forma concisa, o Hospício Pedro II era uma representação da personalidade de Dom Pedro II como um patrono da ciência, a emergência de uma psiquiatria brasileira e da hierarquia da sociedade imperial.

ABSTRACT Objective: Associate Dom Pedro II’s life trajectory and the beginning of Brazilian psychiatry through the Pedro II Asylum. Methods: We conducted a narrative review of the literature on three search databases: Google Scholar, Pub Med, and Web of Science (SciELO). Results: The first Brazilian psychiatry institution, the Pedro II Asylum (1841-1889), was created by the number 82 decree on 18 July 1841. The launching occurred at Dom Pedro II’s coronation ceremony. It was a celebration that aimed at enhancing the Brazilian monarch’s power and at legitimizing the emperor’s adulthood at the age of fourteen. Throughout the 48 years of the Dom Pedro II empire, his cultural and science interests influenced the emergence of incipient Brazilian scientific research. In this regard, the Pedro II Asylum was portrayed not only as a health care institution but also undertook an effort to attend the social and cultural modifications promoted at the Brazilian imperial court after the Portuguese Crown family arrived in 1808. It also represented the influence of French psychiatry based on Phillipe Pinel’s (1745-1826) principles of moral treatment. Conclusions: Concisely, the Pedro II Asylum was a representation of Dom Pedro II’s personality as a patron of science, the emergence of Brazilian psychiatry, and the imperial society hierarchy.

RESUMO Objetivo Revisar sistematicamente as informações disponíveis acerca da função sexual e/ou disfunção sexual em pacientes com transtorno depressivo maior (TDM) e/ou distimia (DIS). Métodos Foi realizada uma busca sistematizada na base eletrônica Medline por estudos que avaliavam a função/disfunção sexual em pacientes com TDM e DIS. Foram incluídos estudos publicados até junho de 2017. Artigos relevantes presentes nas referências dos artigos foram pesquisados manualmente e incluídos nesta revisão. Resultados Vinte estudos foram elegíveis para análise. Foi observada uma grande diversidade de resultados decorrente da heterogeneidade dos delineamentos empregados e devido aos diferentes métodos de avaliação utilizados. De forma geral, os dados provenientes demonstraram uma redução das principais funções sexuais em pacientes com TDM e DIS, tais como: libido (31%-32%), drive (31%-87%), excitação (29%-85%), ereção (18%-46%), lubrificação (18%-79%) e orgasmo (26%-81%). Aumento de libido (15%-22%) também foi descrito em alguns estudos. Conclusão A disfunção sexual é altamente prevalente na DIS e no TDM. Foram notadas diversas alterações de funcionamento sexual na população estudada. Discrepâncias acerca de suas prevalências podem ter ocorrido devido às variadas metodologias de análise utilizadas nos estudos.

ABSTRACT Objective To review the available data on the evaluation of sexual function and/or sexual dysfunction in patients with major depressive disorder (MDD) and/or Dysthymia (DYS) without pharmacological and psychotherapeutic treatment. Methods A systematic electronic search was conducted in the Medline database for studies that evaluated sexual function/dysfunction in patients with MDD and DYS. We included studies published up to June 2017. Relevant articles present in the articles references were manually searched and included in this review. Results Twenty studies were eligible for analysis. It was observed a variety of results due to the heterogeneity of the studies and due to the different evaluation methods used. In general, the data from these studies demonstrated a reduction of the main sexual functions in patients with MDD and DYS such as: libido (31%-32%), drive (31%-87%), arousal (29%-85%), erection (18%-46%), lubrication (18%-79%) and orgasm (26%-81%). Increased libido (15%-22%) has also been described in some studies. Conclusion Sexual dysfunction is highly prevalent in DYS and in MDD. Several sexual functioning alterations were observed in this study population. Prevalence discrepancies may have occurred due to the varied methodologies used in the studies.

OBJETIVO: O objetivo deste estudo foi investigar os efeitos do exercício aeróbio praticado regularmente sobre a ansiedade e o VO2max em pacientes com transtorno de pânico. MÉTODO: Dez mulheres sedentárias diagnosticadas com transtorno de pânico (TP) realizaram 36 sessões de exercícios aeróbico contínuo (70 a 75% VO2max) em esteira, 3x por semana, durante 12 semanas. Uma avaliação cardiopulmonar (teste ergo-espirométrico) definiu a intensidade do treinamento, bem como estabeleceu valores de VO2max pré e pós-treinamento. A avaliação dos sintomas de ansiedade nos três momentos (controle, 6° e 12° semana), foi realizada utilizando os questionários IDATE-T (Inventário do Traço de Ansiedade), IDATE-S (Inventário do Estado de Ansiedade) e SUDS (Unidades Subjetivas da Escala de Aflição). O teste ANOVA One-way para medidas repetidas (momentos) foi usado para comparar os questionários. O teste Bonferroni post-hoc foi aplicado para identificar as diferenças entre os momentos. As medidas de VO2max foram analisadas através de um teste de "t" dependente. RESULTADOS: Os resultados mostraram redução do IDATE-T na 6° e 12° semanas de exercício; no entanto, o IDATE-S e o SUDS monstraram uma redução apenas na 12° semana. O VO2max apresentou melhora significativa após 12 semanas de intervenção em relação à linha de base. CONCLUSÃO: Conclui-se que o protocolo adotado foi capaz de promover efeitos benéficos sobre a aptidão cardiorrespiratória e sobre os níveis de ansiedade dos pacientes com transtorno de pânico.

OBJECTIVE: To investigate the effects of a regularly repeated aerobic exercise series on anxiety and maximum oxygen consumption (VO2max) in Panic Disorder patients. METHODS: Ten previously sedentary female subjects diagnosed with Panic Disorder performed 36 sessions of aerobic exercise (at 70 to 75% of VO2max), 3 times per week during 12 weeks. A cardiopulmonary evaluation (ergospirometry test) was used to set the intensity of training as well as to establish baseline and post-training VO2max parameters. The assessment of anxiety symptoms was performed at baseline, at the end of the 6th and 12th weeks, using the Trait Anxiety Inventory (STAI-T) and State Anxiety Inventory (STAI-S), and the Subjective Units of Distress Scale (SUDS) questionnaires. One-way ANOVA for repeated measurements (at 3 moments: Baseline, 6th week (mid-training) and 12th week (post-training) was used to compare the evolution of the questionnaires; the Bonferroni post hoc test was applied to identify differences between moments. A dependent t-test was performed for measures of VO2max. RESULTS: Compared to baseline, (a) STAI-T showed significant anxiety reductions at mid- and post-training moments; (b) STAI-S and SUDS recorded anxiety reductions only at Post-training; (c) VO2max showed a significant improvement at Post-training. CONCLUSION: This protocol promoted beneficial effects on cardiorespiratory fitness and anxiety levels of Panic Disorder patients.

Relatamos aqui conclusões de um estudo sobre formação inicial de professores, cujos dados foram constituídos durante o processo de reestruturação de um projeto pedagógico de um curso de licenciatura em Física de uma universidade pública. Durante esse processo, foram consideradas a legislação pertinente e as demandas de licenciandos, docentes universitários e de professores de Física em exercício na educação básica que, contribuindo a partir de diferentes posições, colaboraram fornecendo elementos para a configuração final do projeto. Para a leitura e interpretação dos discursos desses segmentos, foram adotadas como referências noções sobre desenvolvimento curricular e análise do discurso. Nesta comunicação, analisamos apenas as contribuições dos licenciandos envolvidos no processo.

We aim to report the outcomes of a broader study on Physics teachers' pre-service education, whose data were collected during the restructuring process of the undergraduate program curriculum in Physics Education , carried out in a Brazilian public university. During this process, it was taken into consideration: the pertinent legislation, pre-service and in-service Physics teachers, and university professors' demands who contributed from different positions for the final project organization. To read and interpret discourses of those involved in this process we adopted notions on curricular development and discourse analysis. In this paper we analyze only contributions of future teachers involved in the process.

INTRODUÇÃO: Existem evidências substanciais sobre o impacto de eventos negativos da vida durante a infância na etiologia dos transtornos psiquiátricos. Examinamos a associação entre os eventos negativos ocorridos na infância e a ansiedade social em uma amostra de 571 estudantes universitários espanhóis. MÉTODOS: Em um estudo transversal realizado em 2007, foram coletados os dados de variáveis sociodemográficas, história psiquiátrica pessoal e familiar e abuso de substâncias por meio de um questionário semiestruturado e avaliamos cinco eventos negativos ocorridos na infância: (i) a perda de alguém próximo, (ii) abuso emocional, (iii) abuso físico, (iv) violência familiar e (v) abuso sexual. Todos os participantes preencheram a escala de Liebowitz para ansiedade social. RESULTADOS: A média (DP) de idade foi de 21 anos (4,5); 75% eram do sexo feminino; o escore na LSAS foi 40 (DP = 22); 14,2% tinham história psiquiátrica familiar e 50,6% tiveram eventos negativos durante a infância. A análise de regressão linear, após o controle para idade, sexo e história psiquiátrica familiar, mostraram associação positiva entre violência familiar e escore de ansiedade social (p = 0,03). Nenhum dos fatores estressores restantes produziu aumento significativo no escore da LSAS (p > 0,05). CONCLUSÃO: Os estudantes universitários com altos níveis de ansiedade social apresentaram prevalência maior de eventos negativos precoces. Portanto, a violência familiar na infância pode ser um fator de risco para ansiedade social em tal população.

INTRODUCTION: There is substantial evidence regarding the impact of negative life events during childhood on the aetiology of psychiatric disorders. We examined the association between negative early life events and social anxiety in a sample of 571 Spanish University students. METHODS: In a cross-sectional survey conducted in 2007, we collected data through a semistructured questionnaire of sociodemographic variables, personal and family psychiatric history, and substance abuse. We assessed the five early negative life events: (i) the loss of someone close, (ii) emotional abuse, (iii) physical abuse, (iv) family violence, and (v) sexual abuse. All participants completed the Liebowitz Social Anxiety Scale. RESULTS: Mean (SD) age was 21 (4.5), 75% female, LSAS score was 40 (DP = 22), 14.2% had a psychiatric family history and 50.6% had negative life events during childhood. Linear regression analyses, after controlling for age, gender, and family psychiatric history, showed a positive association between family violence and social score (p = 0.03). None of the remaining stressors produced a significant increase in LSAS score (p > 0.05). CONCLUSION: University students with high levels of social anxiety presented higher prevalence of negative early life events. Thus, childhood family violence could be a risk factor for social anxiety in such a population.

INTRODUCTION: Androgen decline in the aging man has become a topic of increasing clinical relevance worldwide, as the reduction in testosterone levels has been reported to be accompanied by loss of muscle mass, accumulation of central adiposity, impaired mobility and increase risk of bone fractures. Although well-established in studies conducted in developed countries, progressive decline in serum testosterone levels with age has been poorly investigated in Brazil. AIM: To determine the pattern of blood testosterone concentrations decline with age in a cohort of Brazilian healthy military men. MATERIALS AND METHODS: We retrospectively reviewed data on serum testosterone measurements of healthy individuals that had undergone a routine check-up at the Military Biology Institute. Blood samples were obtained early in the morning, and total testosterone concentration was determined using a commercial chemoluminescent immunoassay. Mean values were analyzed in five age groups: < 40, 41 to 50, 51 to 60, 61 to 70, and > 70 years. MAIN OUTCOME MEASURE: Mean total testosterone levels. RESULTS: 1,623 subjects were included in the analysis; mean age was 57 years (24 to 87), and mean testosterone level was 575.5 ng/dL (25.0 to 1308.0 ng/dL). The evaluation of age-related changes in total testosterone levels revealed a progressive reduction in serum levels of this hormone with increasing age. Testosterone levels below 300 ng/dL were reported in 321 participants, a prevalence of nearly 20% in the study population. CONCLUSION: In agreement with other findings, a reduction of total testosterone levels with age was reported for healthy Brazilian men.

Potencial Auditivo de Tronco Encefálico (PEATE) é um método objetivo e não-invasivo de avaliação das vias auditivas, que detecta a atividade elétrica desde a orelha interna até o colículo inferior. OBJETIVO: Avaliar as vias auditivas em pacientes normo-ouvintes e comparar diferenças de acordo com sexo, idade e lado da orelha (direita e esquerda). Desenho do estudo: Estudo retrospectivo horizontal. MATERIAL E MÉTODOS: Sessenta pacientes normo-ouvintes, com idades entre 09 e 66 anos, foram submetidos a exame otorrinolaringológico e testes audiológicos. RESULTADOS: A disparidade entre as latências das ondas de homens e mulheres foi estatisticamente significante, entretanto, não mostrou diferença entre os lados das orelhas. Comparando as médias das latências de acordo com idade e sexo também foram detectadas significativas desigualdades. Do mesmo modo, foram diagnosticadas diferenças comparando este estudo com o manual do aparelho utilizado e com os resultados encontrados por Fukuda, em outro estudo. CONCLUSÃO: Frente à grande importância do PEATE, torna-se imprescindível que cada serviço desenvolva sua própria normatização, aumentando a precisão diagnóstica eletrofisiológica das vias auditivas.

Brainstem Evoked Response Audiometry (BERA) is an objective and non-invasive method of hearing assessment which detects electrical activity from the inner ear to the inferior colliculus. AIM: To assess the hearing pathway in normal hearing individuals and compare differences associated with gender, age and ear side (left and right). Study Design: A retrospective study. MATERIALS AND METHODS: Sixty normal hearing individuals, aged between 09 and 66 years old, were subjected to clinical ENT examination and audiologic tests. RESULTS: Wave latencies differed significantly between males and females, although there were no differences regarding right or left ear sides. Comparing latency averages regarding age and gender we noticed important differences. By the same token, significant differences were also seen comparing this study with the information present in the handbook of the BERA device used and results published by Fukuda, in another study. CONCLUSION: Knowing the great importance of BERA, it is crucial that each service develops its own standards in order to enhance the accuracy of the electrophysiological diagnosis of the hearing pathway.
