Green management, access to credit, and firms' vulnerability to the COVID-19 crisis.

This paper investigates the consequences of the COVID-19 crisis on firms' performance and financial vulnerability. Exploiting longitudinal firm-level data from the World Bank's "Enterprise Surveys follow-up on COVID-19" for 20 European countries, we assess whether green management quality and pre-pandemic credit access difficulties affect firms' ability to withstand the negative impact of the pandemic. Our results indicate that green firms are more resilient to the pandemic shock. In particular, the likelihood of pandemic-induced drops in sales and liquidity significantly decreases as the quality of green management improves. Conversely, prior financing constraints strongly exacerbate the pandemic's impact on firms' performance and amplify liquidity stress and financing problems. Credit-constrained enterprises are not only more likely to experience liquidity shortages and repayment problems, but they also face higher difficulties in accessing bank financing. The COVID-19 crisis has also hampered the beneficial role that green management exerted on access to credit in the pre-pandemic period. During the pandemic, firms with sound environmental management practices do not benefit from improved access to finance and have a lower demand for credit, possibly suggesting a slowdown in their green investment activities.

The child with medical complexity.

Children with medical complexity represent a big challenge for the physicians, their families and the society as well. Although there is no clear definition of this type of patients, they are affected by a chronic, often very severe condition for their whole life. They also represent a huge cost for the health care system due to their needs of continuous assistance.In this review we summarized the definitions of child with medical complexity. Then we illustrated the strategies to treat and take care of these children in order to look at them not as a burden or a cost but as an opportunity to growth and improve as clinicians and to improve the society, to give them the best life they can live.We also wanted to give voice to the physicians, the parents and the children themselves to really show and understand what are their experiences and their feelings in dealing with their conditions. We concluded with the description of one example of children with medical complexity: prematurity. We discussed the progresses in their treatment so far in order to illustrate what is the future of pediatrics. Since it has been more and more acknowledged that every child with medical complexity is unique, the future of pediatric is to organize an individualized approach and to "see things with the eye of a child".

A review of current knowledge on Pollution, Cigarette Smoking and COVID-19 diffusion and their relationship with inflammation.

Coronavirus disease (COVID-19) is an infectious disease caused by the newly discovered coronavirus, Sars-Cov-2. This infection can cause mild to very severe respiratory and systemic illness mainly related with a cytokine storm. The epidemiology of COVID-19 is under continuous evolution, and studies are ongoing aiming at identifying the possible factors facilitating the diffusion of this infection. It is documented that air pollution and smoking are a leading cause of human morbidity and mortality globally, and can increase the risk of many diseases, including respiratory diseases. Overall, a linear relationship between exposure to atmospheric pollutants and diffusion of the Sars-Cov2 virus seems to exist. However, this correlation, cannot be regarded as a cause-effect relationship.  The available data show that air pollution is responsible for inflammation and hyper-activation of innate immunity that are associated with the worst outcomes of covid-19 but do not allow to conclude that atmospheric particulate is responsible for increased contagion. As to smoking, nicotine activation of nicotinic receptors leads to enhanced protease activation, apoptosis and inflammatory signaling through the same pathways (Renin-angiotensin system (RAS) and angiotensin-converting enzyme 2 (ACE2)) used by the virus increasing the inflammatory/destructive action of the virus itself. The increase in non-communicable diseases and of chronic inflammatory diseases is in line with environmental pollution, related climate changes, and with an augmented susceptibility to infectious diseases with increased contagiousness and morbidity. Restrictive measures to limit environmental pollution are needed worldwide as this represents a threat for human health.
