Lost in the forest of circular economy certificates in tourism sector

[EN] Circular economy represents a paradigm shift compared to the linear economy (producer, use and throw away). This offers the possibility of producing by reducing waste and even seeks mechanisms to reuse them. This concept allows companies to show more responsible behavior. Moreover, it is shown as a source of improvement and efficiency. Circular economy has been implemented for a long time in industrial sectors, but it is not so widespread so far in the tourism sector. However, it is known to be one of the sources of improvement available to tourism companies, and in the last few years, these types of companies are showing great interest in adopting it. One of the difficulties for them is finding the right way to adopt specific measures. One of the paths that help companies to make their efforts more effective and also more visible is going for an official certificate that may show their stakeholders that they are consistent with circular economy principles. For this reason, most of the companies implementing circular economy also seek the reward of the visibility that a certification gives. However, many tourism companies feel lost in the forest of the huge amount of certificates available nowadays in the market, which supposedly analyze and identify such behavior. This article tries to shed some light to help companies within this context.Perello-Marin, MR.; De Miguel Molina, M.; Carrascosa López, C.; Mas Gil, MÁ. (2023).

Multinational case-control study of risk factors for the development of late invasive pulmonary aspergillosis following kidney transplantation

Objectives: To assess the risk factors for development of late-onset invasive pulmonary aspergillosis (IPA) after kidney transplantation (KT). Methods: We performed a multinational case-control study that retrospectively recruited 112 KT recipients diagnosed with IPA between 2000 and 2013. Controls were matched (1:1 ratio) by centre and date of transplantation. Immunosuppression-related events (IREs) included the occurrence of non-ventilator-associated pneumonia, tuberculosis, cytomegalovirus disease, and/or de novo malignancy. Results: We identified 61 cases of late (>180 days after transplantation) IPA from 24 participating centres (accounting for 54.5% (61/112) of all cases included in the overall study). Most diagnoses (54.1% (33/61)) were established within the first 36 post-transplant months, although five cases occurred more than 10 years after transplantation. Overall mortality among cases was 47.5% (29/61). Compared with controls, cases were significantly older (p 0.010) and more likely to have pre-transplant chronic obstructive pulmonary disease (p 0.001) and a diagnosis of bloodstream infection (p 0.016) and IRE (p <0.001) within the 6 months prior to the onset of late IPA. After multivariate adjustment, previous occurrence of IRE (OR 19.26; 95% CI 2.07–179.46; p 0.009) was identified as an independent risk factor for late IPA. Conclusion: More than half of IPA cases after KT occur beyond the sixth month, with some of them presenting very late. Late IPA entails a poor prognosis. We identified some risk factors that could help the clinician to delimit the subgroup of KT recipients at the highest risk for late IPA
