Going Beyond Blockchain Adoption's Hype to Improve Supply Chain Sustainability: Evidence From Empirical and Modelling Studies

Potential solutions emerge with the fourth Industrial Revolution technologies, including the Internet of Things, Artificial Intelligence and Blockchain. The global supply chain requires greater traceability and transparency to ensure product security, efficient management and sustainable performance. However, traditional supply chains face several challenges related to traceability systems. This paper aims to analyse academic literature regarding Blockchain adoption in supply chains to improve traceability and transparency from a sustainable perspective. A systematic literature review was performed in order to provide verifiable evidence; we focused our investigation on empirical and modelling articles. Results suggest that Blockchain benefits occur through three levels: macro-level (overall supply chain network), meso-level (such as dyadic relationships) and micro-level (end consumers). However, we note that the contribution’s results have not yet reached a consensus. We have therefore proposed three research insights towards addressing the identified gaps

Programa da Saúde do Estudante Universitário do Centro de Ciências da Saúde - PSEU-UFRJ

Introdução Nos últimos anos aumentou o ingresso de estudantes nas universidades. Essa expansão representa uma oportunidade de ações de promoção da saúde, em especial prevenindo comportamentos de risco. O estudante universitário passa por processo de transição na vida que pode acarretar alterações na sua dinâmica social envolvendo transformações físicas, emocionais, busca de independência, autonomia e contato com novas experiências, considerado como um período de maior vulnerabilidade. Práticas não saudáveis de forma individual e coletiva levam a um comportamento de risco à saúde, tais como o consumo alimentar inadequado, uso abusivo de álcool e tabagismo. Estes comportamentos estão associados e podem predispor a doenças crônicas no futuro. Objetivo Apresentar o Programa da Saúde do Estudante Universitário do Centro de Ciências da Saúde (CCS)- PSEU-UFRJ. Metodologia Descrever o processo de criação, seus objetivos, metodologia de implantação e resultados preliminares do PSEU-UFRJ. Resultados O PSEU-UFRJ é um programa acadêmico que objetiva promover a saúde do estudante de graduação do CCS. Foi elaborado e proposto pela Coordenação de Projetos Especiais da Decania com apoio do Laboratório Multidisciplinar de Pesquisa em Epidemiologia e Saúde da Faculdade de Medicina, aprovado no Conselho de Centro-CCS e na Congregação da FM. A metodologia adotada foi conhecer os principais comportamentos de risco dos estudantes e suas magnitudes através de inquéritos periódicos. A partir desses resultados formular estratégias e ações para minimizar os problemas encontrados e avaliar a efetividade de tais ações. Pretende-se vincular alunos de iniciação cientifica e pós-graduandos interessados. Os inquéritos por via eletrônica foram aprovados por Comite de Ética em Pesquisa. Foram realizados dois inquéritos, no primeiro e segundo semestre (2023) e aproximadamente 550 alunos responderam. Discussão No Brasil experiências semelhantes ao PSEU-UFRJ em universidades são escassas. Países de alta renda investem em estudos periódicos, a nível nacional, de prevenção de comportamentos de risco no ensino médio. Trata-se, portanto, de uma experiencia inovadora, que poderá contribuir para a melhora da saúde dos estudantes assim como do seu rendimento acadêmico. Todas as etapas serão monitoradas possibilitando acumular conhecimentos com a experiencia no CCS. Conclusões O PSEU-UFRJ pretende implantar intervenções que visando a promoção da saúde do estudante do CCS. Essa implantação acumulara conhecimentos e experiencia permitindo aprimorar o PSEU-UFRJ e expandir para outros Centros.   Palavras-chaves: estudantes, universitário, comportamento de risco, doenças crônicas não transmissíveis

Evolution over Time of Ventilatory Management and Outcome of Patients with Neurologic Disease∗

OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p < 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p < 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p < 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease

Geoeconomic variations in epidemiology, ventilation management, and outcomes in invasively ventilated intensive care unit patients without acute respiratory distress syndrome: a pooled analysis of four observational studies

Background: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference -1·69 [-9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5-8] vs 6 [5-8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52-23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75-0·86]; p<0·0001). Interpretation: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status
