The promising results of the first in-human clinical study using A2AR antagonists for treatment of renal cell carcinoma highlight two decades of research into the hypoxia-A2-adenosinergic pathway. Importantly, clinical responses have been observed in patients who previously progressed on anti-PD-1/PDL-1 therapy, emphasizing the clinical importance of targeting A2AR signaling in cancer immunotherapies. Recently, it has been shown that systemic oxygenation weakens all known stages of the hypoxia-A2-adenosinergic axis. Therefore, we advocate the clinical use of systemic oxygenation and oxygenation agents in combination with A2AR blockade to further improve cancer immunotherapies. This approach is expected to completely eliminate the upstream (hypoxia-HIF-1α) and downstream (adenosine-A2AR) stages of the immunosuppressive hypoxia-adenosinergic signaling axis.

Comorbidities can impose diagnostic and treatment challenges in patients with multiple sclerosis (MS). Sickle cell disease (SCD) and MS are both inflammatory diseases featuring immune system dysregulation, and the reciprocal interaction of these diseases deserves investigation.

We present the case of a 28-year-old woman with SCD who developed a sickle cell crisis and acute chest syndrome during corticosteroid treatment for a first MS attack. We then provide a review of the literature on co-management of SCD and MS. In patients with SCD experiencing an acute MS exacerbation, pre-treatment with red blood cell exchange transfusion before corticosteroids may reduce adverse vaso-occlusive events. Plasma exchange may also be considered. Finally, we discuss innovative pre-clinical research that suggests that natalizumab or dimethyl fumarate may ameliorate SCD symptoms while preventing MS relapses; human trials, however, are needed.

The co-occurrence of inflammatory disorders, in this case MS and SCD, requires providers to appropriately manage each condition with consideration of the other. Future studies may generate shared avenues for treatment.

The causes of brugada phenocopy are usually reversible. Once the reversible condition resolves, the ECG pattern disappears. There are many conditions that cause brugada phenocopy like myocardial infarction, hyperkalemia etc. Here we report a case of brugada phenocopy induced by consumption of yellow oleander seeds (T. Peruviana).Ablation of premature ventricular contractions (PVCs), relies mostly on a detailed activation mapping. This can be impossible to achieve in case of paucity or even absence of PVCs during the procedure. Pacemapping as an alternative has many limitations. We present a case of a patient with very frequent symptomatic PVCs, that on the day of the procedure had total absence of PVCs. We performed successful ablation based exclusively on electrocardiographic imaging confirmed by substrate mapping.This paper reports 6 cases of patients affected by coronavirus disease 2019 bilateral pneumonia with associated acute respiratory distress associated and signs of acute right ventricular hypertrophy on electrocardiography despite the absence of acute pulmonary embolism or signs of severe pulmonary hypertension on transthoracic echocardiography. These cases suggest a possible connection between acute elevated right ventricular afterload and acute respiratory distress in patients affected by SARS-CoV-2.The performance of the cathode significantly affects the ability of the electro-Fenton (EF) process to degrade chemicals. In this study, a simple method to modify the graphite felt (GF) cathode was proposed, i.e. oxidizing GF by hydrothermal treatment in nitric acid. The surface physical and electrochemical properties of modified graphite felt were characterized by several techniques scanning electron microscope (SEM), water contact angle, X-ray photoelectron spectroscopy (XPS), Raman spectroscopy and linear scanning voltammetry (LSV). Compared with an unmodified GF (GF-0), the oxygen reduction reaction (ORR) activity of a modified GF was significantly improved due to the introduction of more oxygen-containing functional groups (OGs). Furthermore, the results showed that GF was optimally modified after 9 h (GF-9) of treatment. As an example, the H2O2 generation by GF-9 was 2.26 times higher than that of GF-0. After optimizing the process parameters, which include the initial Fe2+ concentration and current density, the apparent degradation rate constant of levofloxacin (LEV) could reach as high as 0.40 min-1. Moreover, the total organic carbon (TOC) removal rate and mineralization current efficiency (MCE) of the modified cathode were much higher than that of the GF-0. Conclusively, GF-9 is a promising cathode for the future development in organic pollutant removal via EF.Simulations of 21st century climate change for Great Britain predict increased seasonal precipitation that may lead to widespread soil loss by increasing surface runoff. Land use and different vegetation cover can respond differently to this scenario, mitigating or enhancing soil erosion. Here, by means of a sensitivity analysis of the PESERA soil erosion model, we test the potential for climate and vegetation to impact soil loss by surface-runoff to three differentiated British catchments. First, to understand general behaviours, we modelled soil erosion adopting regular increments for rainfall and temperature from the baseline values (1961-1990). Then, we tested future climate scenarios adopting projections from UKCP09 (UK Climate Projections) under the IPCC (Intergovernmental Panel on Climate Change) on a defined medium CO2 emissions scenario, SRES-A1B (Nakicenovic et al., 2000), at the horizons 2010-39, 2040-69 and 2070-99. Our results indicate that the model reacts to the changes of the climatic parameters and the three catchments respond differently depending on their land use arrangement.
