LOCUS (LOng Covid–Understanding Symptoms, events and use of services in Portugal): A three-component study protocol

Approximately 10% of patients experience symptoms of Post COVID-19 Condition (PCC) after a SARS-CoV-2 infection. Akin acute COVID-19, PCC may impact a multitude of organs and systems, such as the cardiovascular, respiratory, musculoskeletal, and neurological systems. The frequency and associated risk factors of PCC are still unclear among both community and hospital settings in individuals with a history of COVID-19. The LOCUS study was designed to clarify the PCC's burden and associated risk factors. LOCUS is a multi-component study that encompasses three complementary building blocks. The "Cardiovascular and respiratory events following COVID-19" component is set to estimate the incidence of cardiovascular and respiratory events after COVID-19 in eight Portuguese hospitals via electronic health records consultation. The "Physical and mental symptoms following COVID-19" component aims to address the community prevalence of self-reported PCC symptoms through a questionnaire-based approach. Finally, the "Treating and living with Post COVID-19 Condition" component will employ semi-structured interviews and focus groups to characterise reported experiences of using or working in healthcare and community services for the treatment of PCC symptoms. This multi-component study represents an innovative approach to exploring the health consequences of PCC. Its results are expected to provide a key contribution to the optimisation of healthcare services design.info:eu-repo/semantics/publishedVersio

Individual-environment interactions in swimming: The smallest unit for analysing the emergence of coordination dynamics in performance?

Displacement in competitive swimming is highly dependent on fluid characteristics, since athletes use these properties to propel themselves. It is essential for sport scientists and practitioners to clearly identify the interactions that emerge between each individual swimmer and properties of an aquatic environment. Traditionally, the two protagonists in these interactions have been studied separately. Determining the impact of each swimmer’s movements on fluid flow, and vice versa, is a major challenge. Classic biomechanical research approaches have focused on swimmers’ actions, decomposing stroke characteristics for analysis, without exploring perturbations to fluid flows. Conversely, fluid mechanics research has sought to record fluid behaviours, isolated from the constraints of competitive swimming environments (e.g. analyses in two-dimensions, fluid flows passively studied on mannequins or robot effectors). With improvements in technology, however, recent investigations have focused on the emergent circular couplings between swimmers’ movements and fluid dynamics. Here, we provide insights into concepts and tools that can explain these on-going dynamical interactions in competitive swimming within the theoretical framework of ecological dynamics

Genome of Herbaspirillum seropedicae Strain SmR1, a Specialized Diazotrophic Endophyte of Tropical Grasses

The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes and plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable of colonizing intercellular spaces of grasses such as rice and sugar cane. The genome of H. seropedicae strain SmR1 was sequenced and annotated by The Paraná State Genome Programme—GENOPAR. The genome is composed of a circular chromosome of 5,513,887 bp and contains a total of 4,804 genes. The genome sequence revealed that H. seropedicae is a highly versatile microorganism with capacity to metabolize a wide range of carbon and nitrogen sources and with possession of four distinct terminal oxidases. The genome contains a multitude of protein secretion systems, including type I, type II, type III, type V, and type VI secretion systems, and type IV pili, suggesting a high potential to interact with host plants. H. seropedicae is able to synthesize indole acetic acid as reflected by the four IAA biosynthetic pathways present. A gene coding for ACC deaminase, which may be involved in modulating the associated plant ethylene-signaling pathway, is also present. Genes for hemagglutinins/hemolysins/adhesins were found and may play a role in plant cell surface adhesion. These features may endow H. seropedicae with the ability to establish an endophytic life-style in a large number of plant species

Economia de Nado: Parametro Determinante na Avaliaçao e no controlle do treino

A natação pura desportiva é uma modalidade individual, cíclica (os movimentos realizados pelo nadador ocorrem de maneira sequenciada), fechada (o desempenho desportivo depende mais de questões inerentes ao praticante do que do comportamento do adversário) e contínua (não existem momentos de pausa em oposição às modalidades intermitentes, como, por exemplo, o polo aquático). A natação pura desportiva é igualmente uma modalidade mista, uma vez que o rendimento do nadador é determinado por fatores bioenergéticos e por parâmetros biomecânicos. Essa dependência biofísica para o desempenho desportivo em natação é evidenciada na equação do rendimento desportivo1: v = E · (e · D-1) (1) Nesta equação, a velocidade de nado [v], indicador por excelência do rendimento desportivo do nadador, depende de dois fatores: (i) do [E] (input energético total, decorrente do metabolismo aeróbio e anaeróbio) e (ii) da razão entre [e] (eficiência mecânica propulsiva total) e [D] (força de arrasto hidrodinâmico oposta ao deslocamento do nadador), a qual reflete a habilidade técnica do nadador. O propósito deste texto é discorrer sobre a importância da economia de nado – um dos parâmetros que infl uenciam o rendimento em natação que mais importância assume para a prestação fi nal nessa modalidade desportiva – na avaliação e no controle do treino de nadadores. De fato, a economia de nado, quantificada e expressa por meio do custo energético, tem sido considerada o melhor preditor bioenergético do rendimento em diferentes formas de locomoção humana, nomeadamente no meio aquático2, e, como tal, deverá ser alvo de estudo de treinadores investigadores ligados a essa modalidade desportiva
