Blood group O candidates have lower lung transplantation rates despite having the most common blood group. We postulated that waitlist outcomes among these candidates and those with other blood types vary with disease severity and lung allocation score (LAS).We performed a retrospective cohort study of 32,772 waitlist candidates using the United Network of Organ Sharing registry from May 2005 to 2020. After identifying an interaction between blood group and LAS, we evaluated the association between blood group and waitlist outcomes within LAS quartiles using unadjusted and adjusted competing risk models.In the lowest LAS quartile, blood group O had a 20% reduced transplantation rate (SHR: 0.80, 95%CI: 0.75-0.85) and higher waitlist death/removal (1.33, 95%CI: 1.15-1.55) compared with group A. Blood group AB had a 52% higher transplantation rate (SHR: 1.52, 95%CI: 1.34-1.73) in the lowest LAS quartile compared with group A. In the highest LAS quartile, there was no difference in transplantation rates between groups O and A. In contrast, group B had a 19% reduced transplantation rate (SHR, 0.81 95%CI: 0.73-0.89) and AB had a 28% reduced transplantation rate (SHR: 0.72, 95%CI: 0.61-0.86) in the highest LAS quartile. Additionally, groups B and AB had increased risk of waitlist death/removal in the highest LAS quartile compared with A (SHR: 1.27, 95%CI: 1.08-1.48; SHR: 1.31, 95%CI: 1.00-1.72).Waitlist outcomes among ABO blood groups vary depending on illness severity, which is represented by LAS. Blood group O has lower transplantation rates at low LAS while groups B and AB have lower transplantation rates at high LAS.

Green Logistics is a relatively new concept, a part of Green Economy, which considers not just economical aspects but also environmental problems. Unlike classic logistics, that looks only for optimal costs, green logistics is making sure that final decisions won’t have a negative effect on the environment or society. It’s making sure that people working in extractions are not exploited, routes are well designed and the environment is not affected. Thanks to Green Logistics concept there were created biofuels, electric trains and were discovered so many ways of benefiting from environment without damaging it., {"references":["1.\tCodul transportului feroviar nr.

This dissertation investigates what are the key component of digital platforms in relation to a wider process of urban transformation. The thesis aims to contribute to an understanding of the multiple forms that digital platforms can take by focusing on alternative spatial articulation and modes of production. By systematising the various normative claims to sharing economy, in which digital platforms and makerspaces are inscribed, I analyse discourses and practices in different urban contexts. After looking at the definitions of sharing economy, digital platforms, and makerspaces as given in the literature, the thesis proposes the concept of Urban Digital Platform (UDP). A UDP is oriented to citizen participation and facilitates the exchange of goods and services at a smaller, generally urban scale: they are both of and for the city and its inhabitants. Through detailed examinations of different cases such as short-term-rent platforms, makerspaces, civic crowdfunding platforms, and care provision and mutual help platforms, I have aimed to expand existing knowledge about the relationship between media technology and the city. The empirical material has been deployed to broaden the academic and societal debates concerning digital platforms. Indeed, the relevance of such enquiries is not limited solely to the academic world, for the practices examined here might have considerable implications for wider social issues such as participation, inclusion and exclusion, and the future development of our cities more broadly.
