RESUMO

Objective: Covid-19 poses a major risk during pregnancy and postpartum, resulting in an increase in maternal mortality worldwide, including in Brazil; however, little research has been conducted into cases of a near miss. This study aimed to describe the frequency of COVID-19-related near miss and deaths during pregnancy or in the postpartum in referral centers in northeastern Brazil, as well as the clinical, epidemiological, and laboratory characteristics of the women who experienced a severe maternal outcome.Methods: A retrospective and prospective cohort study was performed between April 2020 and June 2021 with hospitalized pregnant and postpartum women with a diagnosis of COVID-19 confirmed by real-time polymerase chain reaction (RT-PCR). Data from five tertiary hospitals in northeastern Brazil were evaluated. Descriptive statistical analysis was performed using Epi Info, version 7.2.5.0.Results: A total of 463 patients were included. Of these, 64 (14% of the sample) had a severe maternal outcome, with 42 cases of near miss (9%) and 22 maternal deaths (5%). Patients who had a severe maternal outcome were predominantly young (median age 30 years) and 65.6% were black or brown-skinned. The women had between 6 and 16 years of schooling; 45.3% had a stable partner; 81.3% were pregnant at the time of admission to the study; and 76.6% required a Cesarean section. The great majority (82.8%) had severe acute respiratory syndrome (SARS). Other complications included hypertensive syndromes (40.6%), pneumonia (37.5%), urinary tract infections (29.7%), acute renal failure (25.0%) and postpartum hemorrhage (21.9%). Sepsis developed in 18.8% of cases, neurological dysfunction in 15.6%, and hepatic dysfunction and septic shock in 14.1% of cases each. The relative frequency of admission to an intensive care unit was 87.5%, while 67.2% of the patients required assisted mechanical ventilation, and 54.7% required noninvasive ventilation. Antibiotics were prescribed in 93.8% of cases and corticosteroids in 71.9%, while blood transfusion was required in 25.0% of cases and renal replacement therapy in 15.6%. Therapeutic anticoagulants were administered to 12.5% of the patients. Of the patients who had a severe maternal outcome, the frequency of respiratory dysfunction was 93.8%, with 50.0% developing neurological dysfunction and 37.5% cardiovascular dysfunction. Hematological dysfunction was found in 29.7%, renal dysfunction in 18.8%, and uterine dysfunction in 14.1%. Hepatic dysfunction occurred in 7.8% of the sample. The near-miss ratio for Covid-19 was 1.6/1000 live births and the maternal mortality ratio for Covid-19 was 84.8/100,000 live births, with a mortality index of 34.4% in the sample.Conclusion: This study revealed a low Covid-19-related maternal near miss (MNM) ratio of 1.6/1000 live births and a high Covid-19-related maternal mortality ratio (MMR) of 84.81/100,000 live births. The mortality index was also high. Most of the patients were admitted while pregnant, were young, married and black or brown-skinned, and none had completed university education. The majority had SARS and required admission to an intensive care unit and mechanical ventilation. Most were submitted to a Cesarean section.

RESUMO

ABSTRACT: Brazil has the world's second largest forest area, which makes the exploitation and use of varied species in civil construction conducive. One of the traditional uses of wood is to build roofs for different purposes. Considering that the most recurrent pathologies in the roof structures are related to the excessive deformations observed in the structural elements, particularly in those subjected to bending. This study verified the effective representativeness of the stiffness value established by the Brazilian Class wood standard, C40. Batches of eight different tropical wood species were considered, whose framing occurred in the referred Class. Results obtained from the confidence intervals for each evaluated species led to the conclusion that the value of 19500 MPa for the modulus of elasticity is not representative for Class C40 because the value observed in this study was 14467 MPa, which is 26% lower than the normative reference. This observation is an initial indication that the adoption of the value of 19500 MPa by the standard is unfavorable to the safety of the structure, justifying the pathologies observed in the service performance of the roof structures.

RESUMO: O Brasil é o segundo maior país em área de florestas no mundo, o que torna propícia a exploração e uso de espécies variadas na construção civil. Um dos usos tradicionais da madeira se dá nos telhados das edificações para as mais diferentes finalidades. Tendo em vista que as patologias mais recorrentes nas estruturas de cobertura estão relacionadas às deformações excessivas verificadas nos elementos estruturais, principalmente nos sujeitos à flexão, o presente trabalho teve como objetivo verificar a efetiva representatividade do valor médio do módulo de elasticidade na compressão paralela estabelecido pela norma brasileira para madeiras da Classe C40. Foram considerados lotes de oito diferentes espécies de madeira tropicais, cujo enquadramento se deu na referida Classe. Os resultados obtidos dos intervalos de confiança para cada espécie avaliada possibilitaram concluir que o valor de 19500 MPa para o módulo de elasticidade não é representativo para a Classe C40, pois o valor encontrado nessa pesquisa foi 14467 MPa, resultado esse 26% inferior à referência normativa. Essa constatação é um indicativo inicial de que a adoção do valor de 19500 MPa pela norma é desfavorável à segurança da estrutura, justificando as patologias observadas no desempenho em serviço das estruturas de cobertura.

RESUMO

Introduction: The adolescence is a process marked by vertiginous biopsychosocial changes, being related to the formation of personality and sexual manifestations. These factors, added to disinformation and the social context in which adolescents are inserted, expose them to a greater vulnerability to Sexually Transmitted Diseases (STD), a condition that deserves a special attention from public health policies. Objective: The objective of this study is to outline the sociocultural profile of adolescents and their relationship with STD awareness, in addition to collaborate to a healthy sexual behavior. Methods: The cross-sectional and descriptive observational study used a sample of 489 students from the 9th grade of 18 municipal public schools in the city of Juiz de Fora, Minas Gerais State, and applied a semistructured questionnaire with a posterior analysis of the collected data. Furthermore, educational lectures were promoted by using audiovisual resources and musical presentations performed by medicine students from Federal University of Juiz de Fora (Universidade Federal de Juiz de Fora ­ UFJF). Results: Results indicate insufficient knowledge and social responsibility among adolescents against the difficulties that the practice of sexuality imposes, besides factors that potentially contribute for the vulnerability of young people. In that context, although 26.2% of adolescents have already began their sexual life, the rate of 81.3% of condom use is unsatisfactory. Moreover, only 37.4% declared themselves to be entangled in the school environment and 61.5% reported full social acceptance, which suggests the necessity of chasing acceptance through sexual permissiveness behavior. Also, it is worth mentioning the use of licit drugs of 15.3%. Conclusion: The study shows that, despite their sexual initiation, adolescents' knowledge about STD is unsatisfactory, exposing, thus, their need to be perceived as vulnerable in the context of public health policies. Carrying out activities at school is a strategy to stimulate their well-being in the experience of sexuality

Introdução: A adolescência, fase de vertiginosas transformações biopsicossociais, está intrincada à formação da personalidade e às manifestações sexuais. Esses fatores, somados à desinformação e ao contexto social no qual estão inseridos, expõem os adolescentes a uma maior vulnerabilidade às doenças sexualmente transmissíveis (DST), condição que merece especial atenção das políticas públicas de saúde. Objetivo: O estudo visa traçar o perfil sociocultural dos adolescentes e sua relação com o conhecimento destes acerca das DST, além de incentivar práticas sexuais seguras. Métodos: O estudo observacional transversal e descritivo utilizou amostra de 489 estudantes do 9º ano de 18 escolas públicas municipais da cidade de Juiz de Fora, Minas Gerais, sendo realizadas aplicação de questionário semiestruturado e posterior análise dos dados obtidos. Além disso, foram efetuadas palestras educativas e apresentação musical pelos discentes do curso de Medicina da Universidade Federal de Juiz de Fora (UFJF). Resultados: Os resultados apontam para conhecimento e responsabilidade social insuficientes dos adolescentes diante dos desafios que o exercício da sexualidade impõe, além de fatores potencialmente contribuintes para a vulnerabilidade dos jovens. Nesse contexto, apesar de 26,2% já terem iniciado sua vida sexual, o índice de 81,3% deles usando preservativos é insatisfatório. Além disso, apenas 37,4% declararam-se enturmados no ambiente escolar e 61,5% relataram aceitação social completa, sugerindo a necessidade de busca de aceitação por comportamentos de permissividade sexual. Destaca-se ainda o uso de drogas ilícitas de 15,3%. Conclusão: O estudo mostra que, apesar de iniciada a vida sexual, o conhecimento dos adolescentes é insatisfatório acerca das DST, expondo, assim, a necessidade de estes serem encarados como vulneráveis no âmbito das políticas públicas de saúde, sendo a realização de atividades na escola uma estratégia estimuladora do bem-estar na vivência da sexualidade.
