OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

RESUMO A pimenta-de-cheiro, Capsicum chinense é uma cultura importante na Bacia Amazônica, cultivada principalmente por pequenos produtores. Plantas de C. chinense em um campo experimental localizado no norte do estado brasileiro do Amazonas, foram encontradas apresentando sintomas característicos de infecção viral. Extratos de amostras de folhas sintomáticas examinados ao microscópio eletrônico de transmissão revelaram a presença de partículas alongadas e flexuosas e de partículas isométricas. Análises moleculares permitiram identificar a presença do pepper yellow mosaic virus (PepYMV) e do cucumber mosaic virus (CMV). Pulgões, identificados como Aphis gossypii foram encontrados colonizando pimenteiras-de-cheiro neste campo experimental e podem representar o provável vetor de PepYMV e CMV. Este trabalho relata a primeira ocorrência desses vírus infectando C. chinense no estado do Amazonas.
ABSTRACT The habanero chilli pepper, Capsicum chinense is an important crop in the Amazon Basin, mainly grown by small-scale producers. Capsicum chinense plants in an experimental field in the northern Brazilian state of Amazonas were found exhibiting characteristic symptoms of viral infection. Leaf sap from symptomatic plants examined under a transmission electron microscope revealed the presence of elongated flexuous particles and isometric particles. Using molecular assays, the viruses were identified as pepper yellow mosaic virus (PepYMV) and cucumber mosaic virus (CMV). Aphids, identified as Aphis gossypii, were found colonizing the C. chinense plants in the field and may be the vector for both PepYMV and CMV. We report the first occurrence of these viruses infecting C. chinense in the state of Amazonas.

RESUMO: A doença respiratória dos bovinos (DRB) é considerada a principal causa de perdas econômicas nas produções de leite e carne. O objetivo deste estudo foi detectar as mais importantes bactérias relacionadas a doença respiratória presentes em amostras de lavado traqueobrônquico de bezerros sadios e com sinais clínicos da DRB de assentamentos brasileiros. Cento e quarenta e um bezerros leiteiros sem raça definida foram randomicamente selecionados de 42 rebanhos leiteiros de assentamentos brasileiros. Exame físico foi realizado e os animais foram classificados em sadios (n=100) e com DRB (n=41). Amostras de lavado traqueobrônquico foram coletadas. Foram realizados o isolamento e a detecção molecular de Mycoplasma dispar, M. bovis e M. mycoides subsp. mycoides SC além de isolamento de outras bactérias aeróbias. Ruídos pulmonares anormais (crepitação/ ronco/sibilo), secreção nasal mucopurulenta/purulenta, temperatura corporal >39.5°C e frequência respiratória >40 movimentos respiratórios/min foram observados com maior frequência em bezerros com DRB comparado aos animais sadios (P<0.05). Bacillus sp, Staphylococcus intermedius e bactérias Gram-negativas não fermentadoras foram as bactérias mais prevalentes. Bactérias da família Enterobacteriaceae cuja espécie não fora identificada foram mais frequentes em bezerros com DRB comparado aos bezerros sadios (P<0.05). Mollicutes foram isolados em 7,4% das amostras e somente M. dispar foi detectado. Mollicutes foi associado à secreção nasal purulenta/mucopurulenta (P=0.017). Pantoea agglomerans foi associada a taquipneia (P=0.020), e Streptococcus spp. Foi associado a hipertermia. Tendência estatística foi observada para M. dispar e taquipneia (P=0.066), e P. agglomerans e taquicardia (P=0.066). Os resultados obtidos descrevem os micro-organismos encontrados no lavado traqueobrônquico de bezerros com DRB em rebanhos de agricultura familiar brasileira e sua relação com as manifestações clínicas da DRB.
ABSTRACT: Bovine respiratory disease (BRD) is considered the major cause of economic losses in dairy and beef cattle production. The study aimed to detect the most important bacteria related to respiratory disease in tracheobronchial fluid samples of healthy and dairy calves with clinical signs of BRD in Brazilian rural settlements. Hundred and forty-one mongrel dairy calves were randomly selected from 42 family farm dairy herds from Brazilian settlements. Physical examination was performed and calves were classified as healthy (n=100) and BRD (n=41). Tracheobronchial fluid samples were collected. Isolation and molecular detection of Mycoplasma dispar, M. bovis and M. mycoides subsp. mycoides SC besides isolation of other aerobic bacteria were performed. Abnormal lung sounds (crackle/snoring/whistle), mucopurulent/purulent nasal discharge, body temperature >39.5°C and respiratory rate >40 breaths/min were higher in BRD calves compared to healthy calves (P<0.05). Bacillus sp., Staphylococcus intermedius and non-fermentative Gram-negative were the most prevalent bacteria isolated. Non-identified species from Enterobacteriaceae family was higher in BRD calves compared to healthy calves (P<0.05). Mollicutes were isolated in 7.4% of samples and only M. dispar was detected. Mollicutes was associated with purulent/mucopurulent nasal discharge (P=0.017). Pantoea agglomerans was associated to tachypnea (P=0.020), and Streptococcus spp. was associated with hyperthermia. Statistical tendencies were observed to M. dispar and tachypnea (P=0.066), and P. agglomerans and tachycardia (P=0.066). The obtained results describe the microorganisms found in tracheobronchial fluid of calves with BRD in some herds of Brazilian family farming and their relation to clinical signs of BRD.

Abstract Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) have increasingly been reported in healthy communities. This study aimed to assess the rate of S. aureus in general and MRSA in particular from nasal secretion of children in daycare centers in Vitória da Conquista, Brazil. The isolates were identified based on morphology, biochemical tests and by PCR. Detection of virulence genes, biofilm production, and susceptibility test by disk diffusion agar were performed. MRSA isolates were characterized by spa, SCCmec, and multilocus sequence typing (MLST). S. aureus were recovered from 70 (47.3%) of 148 children. Among the 11 MRSA strains (15.7%), two SCCmec types (IV and V) were detected. MLST identified four STs related to three clonal complexes (CC): 5, 45, and 398. Four spa types were found circulating in this setting. Resistance of S. aureus isolates to ampicillin, erythromycin, ciprofloxacin, clindamycin, and tetracycline was 80%, 32.8%, 7.1%, 7.1% and 4.3%, respectively. One isolate presented intermediate resistance to vancomycin detected by Etest methodology. All strains were biofilm producers. The virulence genes seb, sec, spa, and pvl were detected in some isolates. This study revealed a high rate of children carrying MRSA among healthy attendees in daycare centers in Vitória da Conquista, Brazil.

Abstract Ovine/caprine ureaplasmas have not yet been assigned a species designation, but they have been classified into nine serotypes. Herein ureaplasmas were searched for in 120 samples of vulvo vaginal mucous from sheep and 98 samples from goats at 17 farms. In addition, semen samples were collected from 11 sheep and 23 goats. The recovered ureaplasma were from sheep and goats from animals without any reproductive disorder symptoms, but not all animals presented positive cultures. In sheep, 17 (68%) cultures of vulvovaginal mucous were positive for ureaplasma and 11 (27%) samples of semen presented positive cultures in animals with clinical signs of orchitis, balanoposthitis or low sperm motility. In goats four ureaplasma isolates were obtained from vulvovaginal mucus, but the semen samples were all negative. The isolates were submitted to Pulsed-field gel electrophoresis methodology and their 16S rRNA genes were sequenced. Fifty percent of ureaplasma recovered from sheep allowed for PFGE typing. Eleven isolates showed eight profiles genetically close to the bovine ureaplasmas. The 16S rRNA gene sequencing showed differences or similarities of isolates from sheep and goats, and the reference strains of bovine and human ureaplasma. Four clinical isolates from sheep were grouped separately. The studied ureaplasma isolates showed to be a diverse group of mollicutes.

RESUMO A utilização de plantas tolerantes ao estresse salino é necessária para remediar o problema da salinidade e/ou sodicidade em regiões semiáridas. Deste modo, o coqueiro anão (Cocos nucifera L.) vem se destacando como uma cultura tolerante ao estresse salino, porém pouco se sabe sobre os mecanismos que contribuem para a tolerância dessa espécie. Neste contexto, objetivou-se com este trabalho avaliar as respostas fisiológicas e iônicas de mudas de coqueiro anão em função do estresse salino. Os tratamentos compreenderam cinco níveis de salinidade da água de irrigação - CEa: 0,9 (tratamento controle); 5,2; 10,1; 15,3 e 19,3 dS m-1 em delineamento inteiramente ao acaso com quatro repetições. Os elevados teores de solutos orgânicos (carboidratos e N-aminossolúveis) e a retenção de Na+ nas raízes, o que favoreceu a manutenção de baixos valores da relação Na+/K+ nas folhas, indicam que o sistema radicular desempenha papel importante no mecanismo de tolerância das mudas de coqueiro à salinidade. O uso de água salobra com CEa de 5,2 dS m-1 permite a produção de mudas, sem perda de qualidade na fase de viveiro. As mudas foram classificadas como moderadamente tolerantes à salinidade de 10,1 dS m-1 baseado na massa seca total da planta.
ABSTRACT Salt-tolerant plants are important to cope with salinity and/or sodicity problems in semiarid regions. The dwarf coconut palm (Cocos nucifera L.) has emerged as a salt-tolerant crop once established. However, little is known about the mechanisms that contribute to the survival of coconut seedlings under salinity stress. This study aimed to evaluate the effect of saline water on morpho-physiological and biochemical responses of dwarf coconut seedlings. Treatments were composed of five levels of water salinity, expressed by its electrical conductivity (ECw), as follows: 0.9 (control); 5.2; 10.1; 15.3 and 19.3 dS m-1 in a completely randomized design with four replications. The high levels of organic solutes (carbohydrates and soluble amino-N) and Na+ in roots, that contribute to the low values of Na+/K+ ratio in the leaves, suggest that roots play an important role in the mechanism of salt tolerance of coconut seedlings. The use of brackish water with ECw of 5.2 dS m-1 allows seedling production, with no loss of quality. Based on total dry matter accumulation, seedlings were classified as moderately tolerant to the salinity of 10.1 dS m-1.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

"Análise longitudinal da variabilidade intra- e inter-individual da performance e fatores determinantes em nadadores jovens." O objetivo principal do estudo foi acompanhar a variabilidade intra- e inter-individual da performance e dos seus fatores determinantes de nadadores jovens durante duas temporadas competitivas. Trinta nadadores jovens (14 nadadores: 12.33±0.65 anos; 16 nadadoras: 11.15±0.55 anos) foram avaliados ao longo das duas épocas (7 momentos de avaliação). Foi avaliada a performance (100m livres), e variáveis antropométricas, cinemáticas, hidrodinâmicas e de eficiência. Foi observado um efeito do sexo e do nível competitivo. Os nadadores melhoraram em maior quantidade (%) do que as nadadoras. Os nadadores no nível competitivo 2 (ambos os sexos) apresentaram uma intra-variabilidade superior. A performance e as variáveis antropométricas apresentaram uma inter-variabilidade significativa na maior parte dos momentos de avaliação, ao contrário das variáveis hidrodinâmicas, cinemáticas e de eficiência. Dentro de cada nível competitivo as variáveis hidrodinâmicas, cinemáticas e de eficiência foram as que apresentaram uma variabilidade inter-individual superior. Como foi verificado um efeito do sexo e do nível competitivo, treinadores e praticantes devem colocar o foco em treinos específicos e personalizados para cada grupo de nadadores de acordo com o nível competitivo.
The main purpose of this study was to follow-up the intra- and inter-individual variability of young swimmers' performance and determinant factors over two competitive seasons. Thirty young swimmers (14 boys: 12.33±0.65 years-old; 16 girls: 11.15±0.55 years-old) were followed-up throughout two consecutive seasons (seven evaluation moments). Performance (100m freestyle), anthropometric, kinematic, hydrodynamic and efficiency features were evaluated. A gender and skill-level effect was observed. Boys improved in a higher amount (%) comparing to girls. Overall, swimmers in skill-level 2 (both genders) presented a higher intra-individual variability. Performance and anthropometrics showed a significant inter-individual variability in most moments, but hydrodynamics, kinematics and efficiency did not. Within each skill-level hydrodynamics, kinematics and efficiency were the variables that showed a high inter-individual variability. As a gender and skill-level effect was noticed in an age-group of young swimmers, coaches and practitioners should put the focus in specific and customized training plans for each skill-level of swimmers.

El rendimiento y la antropometría mostraron una variabilidad inter-individual significativa en la mayoría de los momentos, lo mismo no ocurrió con la hidrodinámica, la cinemática y la eficiencia. Dentro de cada nivel de habilidad, la hidrodinámica, la cinemática y la eficiencia fueron las variables que mostraron una alta variabilidad inter-individual. Como se ha observado un efecto de sexo e nivel de habilidad, entrenadores y practicantes deben poner el foco en los planes de formación específicos y personalizados para cada nivel de habilidad de los nadadores.

The general methodology of classical trajectories as applied to elementary chemical reactions of the A+BC type is presented. The goal is to elucidate students about the main theoretical features and potentialities in applying this versatile method to calculate the dynamical properties of reactive systems. Only the methodology for two-dimensional (2D) case is described, from which the general theory for 3D follows straightforwardly. The adopted point of view is, as much as possible, that of allowing a direct translation of the concepts into a working program. An application to the reaction O(¹D)+H2->O+OH with relevance in atmospheric chemistry is also presented. The FORTRAN codes used are available through the web page <a href="http://www.qqesc.qui.uc.pt">www.qqesc.qui.uc.pt</a>.
