Clinical and epidemiological aspects of Delta and Gamma SARS-CoV-2 variant of concern from the western Brazilian Amazon

BACKGROUND The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants has become a major concern contributing to increased morbidity and mortality worldwide. OBJECTIVES Here we describe the replacement of the Gamma variant of concern (VOC) with Delta in the western Brazilian Amazon. METHODS In this study, we analysed 540 SARS-CoV-2 positive samples determined by qualitative real-time RT-PCR selected in the state of Rondônia between June and December 2021. The positive cohort was sequenced through next-generation sequencing (NGS) and each sample was quantified using real-time RT-qPCR, the whole genome sequence was obtained, SARS-CoV-2 lineages were classified using the system Pango and the maximum likelihood (ML) method was used to conduct phylogenetic analyses. FINDINGS A total of 540 high-quality genomes were obtained, where the Delta VOC showed the highest prevalence making up 72%, with strain AY.43 being the most abundant, while the Gamma VOC was present in 28%, where the P.1 strain was the most frequent. In this study population, only 32.96% (178/540) had completed the vaccination schedule. MAIN CONCLUSIONS This study highlighted the presence of Gamma and Delta variants of SARS-CoV-2 in RO. Furthermore, we observed the replacement of the Gamma VOC with the Delta VOC and its lineages.

Humanização da assistência prestada à parturiente pela equipe multiprofissional do centro de parto da maternidade escola assis chateaubriand

O trabalho de humanização se constitui na transformação da cultura institucional, por meio da construção coletiva de compromissos éticos e de métodos que visem a atenção à saúde e gestão de serviços, no sentido de respeito e valorização do ser humano. Assistiras mulheres no momento do parto e nascimento com segurança e dignidade é compromisso fundamental de todos os profissionais de saúde envolvidos na atenção à saúde da mulher. Torna-se objetivo desse estudo avaliar aspectos do processo de humanização na assistência prestada à gestante em trabalho de parto pela equipe multiprofissional do Centro de Parto Humanizado da Maternidade Escola Assis Chateaubriand. Estudo transversal, realizado no Centro de Parto Humanizado da Maternidade Assis Chateaubriand, envolvendo 170 puérperas que tiveram seus partos normais.

Análise eletromiográfica dos músculos reto femoral e reto abdominal durante a execução dos exercícios hundred e teaser do método pilates / Electromyographic analysis of the rectus femoris and rectus abdominis muscles during performance of the hundred and teaser pilates exercises

A literatura tem mostrado que pequenas modificações em um exercício do método Pilates podem alterar o padrão de ativação muscular. Além disto, são poucos os estudos que avaliaram exercícios desse método do ponto de vista cinesiológico. Nesta perspectiva, o objetivo deste trabalho foi comparar dois exercícios realizados no solo e em aparelho no que diz respeito à ativação elétrica de grupos musculares atuantes. Participaram do estudo 11 mulheres saudáveis praticantes do método Pilates. Foram coletados dados eletromiográficos dos músculos reto femoral e reto abdominal, porções direita e esquerda, enquanto os exercícios hundred no solo, hundred no Reformer, teaser no solo e teaser no Cadillac eram mantidos na postura isométrica. Foram analisados os cinco segundos centrais de cada execução, normalizados por contração voluntária máxima. A análise estatística apresentou diferença entre a ativação dos grupos musculares, sendo maior no reto femoral, e interação entre músculos e exercício, onde no exercício hundred no solo e no Reformer o reto femoral teve maior ativação, enquanto no exercício teaser o reto abdominal foi mais ativo quando executado no Cadillac. Com base nos resultados do estudo pode-se afirmar que: i) quando comparados os exercícios hundred (no solo e no Reformer) e teaser (no solo e no Cadillac), não houve diferença entre os exercícios no que se refere à ativação dos músculos reto abdominal e reto femoral; ii) quando comparados os grupamentos musculares, o reto femoral apresentou maiores níveis de ativação nos exercícios hundred executado no solo e no Reformer, enquanto o reto abdominal apresentou maior ativação durante o exercício teaser executado no Cadillac.

The literature has shown that small modifications in a Pilates method exercise may change the muscles activation pattern. Moreover, few studies have evaluated Pilates' exercises from the kinesiology point of view. Therefore, this study aimed to compare a couple of exercises performed on the mat and in apparatus regarding electric activation of acting muscle groups. Eleven healthy Pilates trained women took part in the study. Electromyographic data were collected from the rectus femoris and rectus abdominis muscles, right and left portions, while keeping the isometric posture of the hundred on mat, hundred on the Reformer machine, teaser on mat and teaser on the Cadillac machine exercises. The five central seconds of each execution normalized by maximum voluntary contraction were analyzed. Statistical analysis showed difference between the muscle group's activation that was higher for the rectus femoris, and interaction between muscle and exercise, where rectus femoris muscle's electric activation was higher on the hundred exercise performed on mat and Reformer and rectus abdominis muscle's electric activation was higher on teaser performed in the Cadillac machine. Based on the study results, it may be stated that: (i) when compared the hundred (on mat and Reformer) and teaser (on mat and Cadillac) exercises were compared, no difference was found between them regarding rectus abdominis and rectus femoris muscles' activation; (ii) when muscle groups were compared, the rectus femoris presented higher activation levels on the hundred exercise performed on mat and Reformer, while rectus abdominis presented higher activation during the teaser exercise performed on Cadillac.

Chikungunya virus infection: report of the first case diagnosed in Rio de Janeiro, Brazil / Infecção pelo virus Chikungunya: relato do primeiro caso diagnosticado no Rio de Janeiro, Brasil

Initially diagnosed in Africa and Asia, the Chikungunya virus has been detected in the last three years in the Caribbean, Italy, France, and the United States of America. Herein, we report the first case for Rio de Janeiro, Brazil, in 2010.
