The impact of petrol and diesel oil taxes in EU member states on CO2 emissions from passenger cars.

The article aims to explain road CO2 emissions, including passenger car emissions in the EU member states, with the rates of indirect taxes (except VAT) for petrol and diesel oil. Apart from tax rates, the analysis includes some selected variables concerning economies and transport infrastructure, which impact CO2 car emissions. Compared to the existing literature, we focus on emissions from passenger cars and analyse more countries over a more extended period using more updated data. Our findings confirm that fuel taxes have a generally negative but limited impact on emissions from passenger cars. This impact is independent of whether we relate emissions to the number of inhabitants or GDP and is generally stronger in EU member states with higher taxes. In many countries, the economic affordability of fuels has significantly increased over the last few years. This phenomenon is another argument for a more active tax policy, i.e., general adjustment of the tax rates in line with inflation. There is also great importance for those adjustments in times of high fuel prices when governments are under tremendous pressure not only to stop tax increases but to reduce them, which was the case in 2022 after the Russian aggression on Ukraine.

The Value of Clinical Frailty Scale (CFS) as a Prognostic Tool in Predicting Mortality in COVID-19-A Retrospective Cohort Study.

BACKGROUND: Due to the unpredictable nature of COVID-19, there is a need to identify patients at high risk of severe course of the disease and a higher mortality rate. OBJECTIVE: This study aims to find the correlation between frailty and mortality in adult, hospitalized patients with COVID-19. METHODS: Clinical records of 201 patients who suffered from COVID-19 and were hospitalized between October 2020 and February 2021 were retrospectively analyzed. Demographic, clinical, and biochemical data were collected. Patients were assessed using Clinical Frailty Scale (CFS) and were divided into three groups: CFS 1-3 fit; CFS 4-6 vulnerable and with mild to moderate frailty; CSF 7-9, severe frailty. The association between frailty and in-hospital mortality was the primary outcome. RESULTS: Severe frailty or terminal illness was observed in 26 patients (12.94%) from a cohort of 201 patients. Those patients were older (median age 80.73, p < 0.001) and had more comorbidities. Frailty was also associated with higher requirement for oxygen supplementation, greater risk of in-hospital complications and worse biochemical laboratory results. An increase in CFS score also correlated with higher mortality (OR = 1.89, p < 0.001). The Conclusions: Clinical Frailty Scale (CFS) can be used as a potentially useful tool in predicting mortality in patients with COVID-19.

Pathomechanisms in the Kidneys in Selected Protozoan Parasitic Infections.

Leishmaniasis, malaria, toxoplasmosis, and acanthamoebiasis are protozoan parasitic infections. They remain important contributors to the development of kidney disease, which is associated with increased patients' morbidity and mortality. Kidney injury mechanisms are not fully understood in protozoan parasitic diseases, bringing major difficulties to specific therapeutic interventions. The aim of this review is to present the biochemical and molecular mechanisms in kidneys infected with Leishmania spp., Plasmodium spp., Toxoplasma gondii, and Acanthamoeba spp. We present available mechanisms of an immune response, oxidative stress, apoptosis process, hypoxia, biomarkers of renal injury in the serum or urine, and the histopathological changes of kidneys infected with the selected parasites. Pathomechanisms of Leishmania spp. and Plasmodium spp. infections have been deeply investigated, while Toxoplasma gondii and Acanthamoeba spp. infections in the kidneys are not well known yet. Deeper knowledge of kidney involvement in leishmaniasis and malaria by presenting their mechanisms provides insight into how to create novel and effective treatments. Additionally, the presented work shows gaps in the pathophysiology of renal toxoplasmosis and acanthamoebiasis, which need further research.
