Alexandra Jirkovská
Podiatry is the science dealing with the diagnostics and treatment of the foot and ankle and associated tissues and structures by all appropriate methods and also with the local manifestation of the overall processes in this area. Diabetic foot disease is defined as infection, ulceration or destruction of tissues of the foot associated with neuropathy and/or peripheral artery disease in the lower extremity of people with diabetes according to the latest edition of the International Consensus. Successful treatment and prevention of diabetic foot syndrome depends on a holistic approach, in which it is seen as part of the multiple organ involvement...

BACKGROUND/PURPOSE: Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. METHODS/MATERIALS: A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed...

The cardiothoracic ratio (CTR) and peripheral arterial occlusive disease (PAOD) are related to mortality in hemodialysis patients. However, data on the association between PAOD and CTR are limited. In this study, we aim to elucidate this relationship in patients on chronic hemodialysis. Using a retrospective cross-sectional study of 622 Taiwanese patients, we investigated the association of PAOD and CTR. PAOD was significantly associated with CTR in the crude analysis. The odds ratio (OR) for CTR >0.5 was 1...

Hypertensive rats with chronic kidney disease (CKD) exhibit enhanced gamma-aminobutyric acid (GABA)B receptor function and regulation within the nucleus tractus solitarii (NTS). For CKD with hypertension, renal denervation (RD) interrupts the afferent renal sympathetic nerves, which are connecting to the NTS. The objective of the present study was to investigate how RD improves CKD-induced hypertension. Rats underwent 5/6 nephrectomy for 8 weeks, which induced CKD and hypertension. RD was induced by applying phenol to surround the renal artery in CKD...

Progressive impairment of renal function can lead to uremia, which is associated with thus increasing the risk of bleeding as well as thrombosis. Furthermore, many patients with chronic kidney disease (CKD) have an indication for an anticoagulation or antiplatelet therapy due to atrial fibrillation, coronary artery disease, thromboembolic disease, or peripheral artery disease. The treatment usually includes vitamin-K antagonists (VKAs) and/or platelet aggregation inhibitors. The direct oral anticoagulants (DOACs) inhibiting factor Xa or thrombin activity represent an alternative for heparins and VKAs...

Bypass surgery(BSX) and endovascular therapy(EVT) are the most important therapeutic method to critical limb ischemia.EVT has potential advantages in reducing surgical trauma and early postoperative complications, shortening hospital stay and so on. Concerning long-term results, BSX is better in reducing long-term mortality and improving long-term patency than EVT group. Therefore, control indications reasonably and select individualized methods, avoid the abuse of EVT are more meaningful for patients.

NADPH oxidases (NOX) - derived reactive oxygen species (ROS) contribute to oxidative injury in hypoxia-induced pulmonary arterial hypertension. This study aims to evaluate the status of NOX in endothelial progenitor cells (EPCs) under hypoxic condition and to determine whether NOX inhibitors could attenuate hypoxia-induced dysfunctions of EPCs. EPCs were isolated from peripheral blood of SD rats and subjected to hypoxia (O2/N2/CO2, 1/94/5) for 24 h. The cells were collected for β-galactosidase or Hoechst staining, or for functional analysis (migration, adhesion and tube formation)...

INTRODUCTION: Epidermal grafting has several advantages over full-thickness or split-thickness grafts in the treatment of complex non-healing wounds. These include the low risk of donor site complications, minimal patient discomfort, and abstention from the operating room. Traditionally, the lack of reliable epidermal harvesting techniques has limited its clinical utilization. The development of an automated suction blister epidermal graft (SBEG) harvesting device may facilitate clinical utilization of this technique...

BACKGROUND: The goal of carotid artery stenting (CAS) is to decrease the stroke risk in patients with carotid stenosis. This procedure carries an immediate risk of stroke and death and many patients do not benefit from it, especially asymptomatic patients. Patient selection for carotid procedure who benefit from procedure and who is the procedure hazardous for is important. Remote ischemic stroke is known risk factor for stroke reccurence during surgery. The aim of our study was to determine the periprocedural complication risk (within 30 days after CAS) associated with carotid stenting (stroke, death) between patients with remote pre- procedural ischemic stroke and without it; to analyse periprocedural risk in other specific patient subgroups treated with CAS and to determine the impact of observed variables on all- cause mortality during long-term follow-up...

Hemolytic uremic syndrome (HUS) is defined by the simultaneous occurrence of hemolytic anemia, thrombocytopenia, and acute kidney injury due to thrombotic microangiopathy (TMA) mainly occurring in renal and cerebral microvessels. Although the most common cause of HUS in children is Shiga toxin-producing Escherichia coli, atypical forms in which Shiga toxin is not the trigger may occur. Research over the last few years has shown that complement dysregulation secondary to mutations of genes coding for proteins involved in the regulation of the alternative pathway of complement account for most forms of atypical HUS (aHUS)...

OBJECTIVE: Critical leg ischemia (CLI) represents the ultimate stage of peripheral arterial disease. Despite current surgery advances, patients with CLI have limited therapeutic options. Therapeutic angiogenesis thus appears as a powerful approach, aiming to stimulate vessel formation by angiogenic molecules administration. In this context, combined gene therapy has proved the most efficient. The present study aims to compare, in a preclinical mouse model, the therapeutic benefit of a combination of two angiogenic factors FGF2 (fibroblast growth factor 2) and Cyr61 using plasmid and viral vectors, able to generate short or long-term transgene expression in the leg, respectively...

PURPOSE: Type II endoleaks (T2Es) remain the Achilles heel of Endovascular Aneurysm Repair (EVAR), involving a close follow-up and sometimes leading to reintervention. Identifying risk factors impacting T2Es is of concern to improve decision-making and optimize follow-up. However, it has led to contradictory results, with supporting evidence for the majority of factors being weak. METHODS: A systematic review and meta-analysis was conducted to study risk factors of T2Es following EVAR to identify risk factors and measure their dedicated strength of association...
