    O composto orgânico (CO) é um produto da decomposição dos resíduos sólidos que pode ser utilizado na correção da acidez ativa do solo e fonte de nutrientes para as plantas. Desta forma, buscou-se entender as influências do CO sobre o pH do solo durante o período de incubação, como também, seus efeitos no crescimento e desenvolvimento de mudas de Acosmium nitens. Os tratamentos foram constituídos de solo natural (testemunha) e três dosagens de compostagem orgânica (10, 30 e 50%). O efeito do CO sobre o pH do solo foi avaliado pelo delineamento misto de medidas repetidas, constituído de quatro tratamentos, seis repetições e quatro medidas no tempo. Aos 148 dias após o transplantio, o crescimento e desenvolvimento das mudas de Acosmium nitens foram avaliadas pelo delineamento inteiramente casualizado, com quatro tratamentos e seis repetições, com as variáveis: massa seca total, massa seca da parte aérea, matéria seca da raiz, diâmetro do colo, altura da planta, relação diâmetro do colo/altura e índice de qualidade de Dickson. O CO afetou significativamente na correção da acidez ativa do solo e causou interações significativas nos tratamentos durante o tempo de incubação do substrato. O crescimento e o desenvolvimento das plantas foram significativos às dosagens de CO no substrato. Portanto, o CO de resíduos sólidos orgânicos urbanos melhorou o grau da fertilidade e corrigiu a acidez ativa do solo. A suficiência nutricional para as mudas de Acosmium nitens foi alcançada na combinação de 30% de CO adicionado e 70% de solo

    The increase in the number of reported cases of microcephaly in Pernambuco State, and Northeast Brazil, characterized an epidemic that led the Brazilian Ministry of Health to declare a national public health emergency. The Brazilian Ministry of Health initially defined suspected cases as newborns with gestational age (GA) ≥ 37 weeks and head circumference (HC) ≤ 33cm, but in December 2015 this cutoff was lowered to 32cm. The current study aimed to estimate the accuracy, sensitivity, and specificity of different cutoff points for HC, using ROC curves, with the Fenton and Intergrowth (2014) curves as the gold standard. The study described cases reported in Pernambuco from August 8 to November 28, 2015, according to sex and GA categories. The Fenton and Intergrowth methods provide HC growth curves according to GA and sex, and microcephaly is defined as a newborn with HC below the 3rd percentile in these distributions. Of the 684 reported cases, 599 were term or post-term neonates. For these, the analyses with ROC curves show that according to the Fenton criterion the cutoff point with the largest area under the ROC curve, with sensitivity greater than specificity, is 32cm for both sexes. Using the Intergrowth method and following the same criteria, the cutoff points are 32cm and 31.5cm for males and females, respectively. The cutoff point identified by the Fenton method (32cm) coincided with the Brazilian Ministry of Health recommendation. Adopting Intergrowth as the standard, the choice would be 32cm for males and 31.5cm for females. The study identified the need to conduct critical and on-going analyses to evaluate cutoff points, including other characteristics for microcephaly case definition

    O objetivo deste trabalho foi avaliar o efeito do eugenol como anestésico para juvenis de pacamã (Lophiosilurus alexandri). Os animais foram divididos em dois grupos, denominados juvenil I (0,72 g) e juvenil II (7,44 g), e submetidos a seis tratamentos de eugenol (20, 40, 60, 80, 100 e 120 mg L-1), em dez repetições. Durante o experimento, foram realizadas biometrias e cronometragens dos tempos de indução e recuperação. Com o aumento das doses, o tempo de anestesia foi reduzido de 69 para 27 s, em juvenis I, e de 93,8 para 37,3 s em juvenis II. A sobrevivência foi de 100%.The objective of this work was to evaluate the effect of eugenol as an anesthetic in juvenile pacamã (Lophiosilurus alexandri).

    A presente pesquisa avaliou a percepção de colaboradores do setor público e privado, sobre perfil de liderança de seus gestores no período pós-lockdown, decretado no Estado do Pará, e doze meses após esse evento. Na Etapa I deste estudo, participaram 9 colaboradores do setor privado e 13 do setor público, de ambos os sexos, maiores de 18 anos e devidamente contratados por essas organizações. Na Etapa II, somente os 13 servidores públicos participaram deste estudo; os participantes da loja de telefonia não foram autorizados a participar da coleta de dados. Foi utilizado como instrumento de coleta um questionário contendo questões sociodemográficas e a Escala de Liderança Gerencial (MELO, 2014) avaliando os fatores de tarefa, relacionamento e situacional, com os indicadores de concordância: 1 ≥ 2,99 (baixo), 3 ≥ 3,99 (neutra) e 4 ≥ 5 (alto). Os resultados da Etapa I, demonstraram alta percepção de liderança para a gestora do órgão público sob os três fatores (relacionamento, tarefa e situação). Na Etapa II, a nova gestora do setor público apresentou um perfil neutro de liderança e não foi permitida a coleta de dados na loja. Conclui-se que, durante a pandemia, a primeira gestora do órgão público apresentou melhor perfil de liderança em comparação ao líder do setor privado e à nova líder do órgão público. Contudo, o perfil da nova líder do órgão público, pode ter sido avaliado como neutro devido a pouca convivência com a equipe de trabalho ou a obrigatoriedade do retorno presencial ao trabalho durante a pandemia

    Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): study protocol for a randomized controlled trial

    Get PDF
    BACKGROUND: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). METHODS/DESIGN: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH2O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure 6430 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. DISCUSSION: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration metho

    BACKGROUND: A safe and efficacious vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), if deployed with high coverage, could contribute to the control of the COVID-19 pandemic. We evaluated the safety and efficacy of the ChAdOx1 nCoV-19 vaccine in a pooled interim analysis of four trials. METHODS: This analysis includes data from four ongoing blinded, randomised, controlled trials done across the UK, Brazil, and South Africa. Participants aged 18 years and older were randomly assigned (1:1) to ChAdOx1 nCoV-19 vaccine or control (meningococcal group A, C, W, and Y conjugate vaccine or saline). Participants in the ChAdOx1 nCoV-19 group received two doses containing 5 × 1010 viral particles (standard dose; SD/SD cohort); a subset in the UK trial received a half dose as their first dose (low dose) and a standard dose as their second dose (LD/SD cohort). The primary efficacy analysis included symptomatic COVID-19 in seronegative participants with a nucleic acid amplification test-positive swab more than 14 days after a second dose of vaccine. Participants were analysed according to treatment received, with data cutoff on Nov 4, 2020. Vaccine efficacy was calculated as 1 - relative risk derived from a robust Poisson regression model adjusted for age. Studies are registered at ISRCTN89951424 and ClinicalTrials.gov, NCT04324606, NCT04400838, and NCT04444674. FINDINGS: Between April 23 and Nov 4, 2020, 23 848 participants were enrolled and 11 636 participants (7548 in the UK, 4088 in Brazil) were included in the interim primary efficacy analysis. In participants who received two standard doses, vaccine efficacy was 62·1% (95% CI 41·0-75·7; 27 [0·6%] of 4440 in the ChAdOx1 nCoV-19 group vs71 [1·6%] of 4455 in the control group) and in participants who received a low dose followed by a standard dose, efficacy was 90·0% (67·4-97·0; three [0·2%] of 1367 vs 30 [2·2%] of 1374; pinteraction=0·010). Overall vaccine efficacy across both groups was 70·4% (95·8% CI 54·8-80·6; 30 [0·5%] of 5807 vs 101 [1·7%] of 5829). From 21 days after the first dose, there were ten cases hospitalised for COVID-19, all in the control arm; two were classified as severe COVID-19, including one death. There were 74 341 person-months of safety follow-up (median 3·4 months, IQR 1·3-4·8): 175 severe adverse events occurred in 168 participants, 84 events in the ChAdOx1 nCoV-19 group and 91 in the control group. Three events were classified as possibly related to a vaccine: one in the ChAdOx1 nCoV-19 group, one in the control group, and one in a participant who remains masked to group allocation. INTERPRETATION: ChAdOx1 nCoV-19 has an acceptable safety profile and has been found to be efficacious against symptomatic COVID-19 in this interim analysis of ongoing clinical trials.
