COVID-19 ‒ a coronavirus disease, affected almost all countries in the world. It is a new virus disease, nobody has prior immunity to it, human population is prone to infections. In March 11 2020, WHO declared the pandemic status. ⋯ The mechanism might be virus induced oxidative stress causing a mutation of one or more of the nine COQ genes, resulting in primary CoQ10 deficiency. New perspective for patients with COVID-19 may be supportive targeting therapy with coenzyme Q10 to increase the energy production, immunity and decrease oxidative stress (Fig. 1, Ref. 51). Keywords: COVID-19, virus, mitochondrial bioenergetics, coenzyme Q10, oxidative stress.

Transcatheter aortic valve implantation (TAVI) is a well-established management option for symptomatic patients with severe aortic stenosis. The minimally invasive transfemoral approach is considered to be superior to non-transfemoral accesses; however, its use is often limited by concomitant peripheral artery disease (PAD). Percutaneous transluminal angioplasty with stent implantation (PTA) is a gold-standard therapy for symptomatic PAD. ⋯ However, the patients were eventually treated either by staged PTA and TAVI through an endothelialized stent or PTA and TAVI though a newly implanted peripheral stent during one procedure. We provide recommendations based on our experience of how to select the optimal patients for such a combined minimally invasive transfemoral approach (Fig. 2, Ref. 9). Keywords: transcatheter valve implantation, peripheral arterial disease, aortic valve disease, percutaneous intervention, atherosclerosis.

The liver transplantation is a standard treatment method for the indicated group of patients with a final hepatic failure. The aim of this paper was to compare two reperfusion methods of implanted liver, non-venting and venting vena cava, and to evaluate the impact of both techniques on the post reperfusion syndrome. ⋯ Venting via vena cava inferior did not impact the perioperative and early postoperative course of liver transplantation in our group of patients. However, further analyses are required (Tab. 2, Fig. 3, Ref. 20).

This study aims to investigate the effects of zinc and melatonin supplementation on lipid peroxidation in the brain cortex in DMBA-induced breast cancer in female rats. ⋯ There are no reports on whether DMBA-induced experimental breast cancer affects oxidative stress in brain tissue. In this respect, our study revealed that the increased brain cortex tissue damage in DMBA-induced breast cancer is alleviated by Zinc, melatonin, or combined zinc and melatonin treatment (Fig. 3, Ref. 26).
