Disposição a Pagar por Espaços Verdes Urbanos

O artigo buscou responder: quanto os frequentadores do parque Araçá (Recife - Pernambuco) estão dispostos a pagar por melhorias propostas - cenário com melhoria da qualidade ambiental - na área de estudo? Aplicamos o método de valoração contingente para estimar o valor econômico da área, avaliando a Disposição a pagar (DAP) de seus frequentadores. Buscamos entender quais os fatores socioeconômicos contribuem nas preferências dos usuários por visitação ao parque. O modelo adotado foi um Probit Bivariado com perguntas duplas (dicotômicas). Calculamos dois modelos para estimar a DAP – forma funcional linear na renda e forma funcional log linear na renda. O primeiro teve DAP de R$11,71, enquanto o segundo foi de R$ 11,23. O resultado de ambos os modelos mostrou que o valor do lance oferecido a exerce maior influência sobre probabilidade de os entrevistados dizerem sim. E que, fatores como o sexo, a idade e o nível de escolaridade dos entrevistados não se mostraram bons fatores explicativos da aceitação do lance. A distância da moradia em relação parque, o dia em que ocorre a visita e o tempo de visita são variáveis que explicaram bem a aceitação do lance. Ao final calculamos o excedente do consumidor, R$545.151,90 (modelo logLinear) e R$ 568.075,52 (modelo linear).The article sought to answer: how much are regulars at Araçá Park (Recife - Pernambuco) willingness to pay for proposed improvements - a scenario with improved environmental quality - in the study area? We apply the contingent valuation method to estimate the economic value of the area, assessing the willingness to pay (DAP) of its regulars. We seek to understand which socioeconomic factors contribute to users' preferences for visiting the park. The model adopted was a Bivariate Probit with double questions (dichotomous). We calculated two models to estimate DBH - linear functional form in income and functional log linear form in income. The first had a DAP of R $11.71, while the second was R$ 11.23. The result of both models showed that the bid amount offered to exerts a greater influence on the likelihood of respondents saying yes. And that, factors such as sex, age and education level of the interviewees were not good explanatory factors for the acceptance of the bid. The distance from the house to the park, the day on which the visit occurs and the duration time of visit are variables that explained well the acceptance of the bid. At the end, we calculated the consumer surplus, R $545,151.90 (logLinear model) and R$ 568,075.52 (linear model)

Genomics and epidemiology for gastric adenocarcinomas (GE4GAC): a Brazilian initiative to study gastric cancer

Abstract Gastric cancer (GC) is the fifth most common type of cancer worldwide with high incidences in Asia, Central, and South American countries. This patchy distribution means that GC studies are neglected by large research centers from developed countries. The need for further understanding of this complex disease, including the local importance of epidemiological factors and the rich ancestral admixture found in Brazil, stimulated the implementation of the GE4GAC project. GE4GAC aims to embrace epidemiological, clinical, molecular and microbiological data from Brazilian controls and patients with malignant and pre-malignant gastric disease. In this letter, we summarize the main goals of the project, including subject and sample accrual and current findings

Dependência psicológica de Benzodiazepínicos: Psychological dependence on Benzodiazepines

O crescente aumento do seu uso no começo do século XXI, os ansiolíticos vêm se tornando a “porta de fuga” para nova e também velha geração. Geração essa, que cada vez mais vem sendo consumida por distúrbios de ansiedade, insônia e quadros depressivos de forma exponencial. (Faculdade de Ciências Farmacêuticas de Ribeirão Preto – 2019). Este trabalho, avalia o uso e possível dependência psicológica dos benzodiazepínicos, a partir de um levantamento bibliográfico de forma sistemática de pesquisas dentro da literatura científica acerca do assunto.&nbsp

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

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 cmH(2)O 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 <= 30 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 method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt
