This study aims to elucidate the differences in vessel patency rates, procedural complications, and the need for repeat interventions between these two techniques, thereby providing insights into the optimal atherectomy strategy for managing peripheral arterial disease in the femoropopliteal segment. This retrospective study investigated the long-term effectiveness of two atherectomy techniques, rotational atherectomy (RA) and directional atherectomy (DA), in treating lower extremity peripheral artery disease (LE-PAD) affecting the superficial femoral artery (SFA) and popliteal arteries. A total of 134 patients with symptomatic LE-PAD and significant stenosis (70%-99%) were included and divided into two groups based on the atherectomy method used.

Specialized pro-resolving lipid mediators (SPMs), derived from polyunsaturated fatty acids are important mediators in the resolution of inflammation. Recent studies have focused on the effects of SPMs in cardiovascular health and diseases. However, little is known about the effect SPMs on human vascular tone.

Background: Constrictive pericarditis (CP) is a pericardial disease characterized by the pericardium becoming calcified or fibrotic as a result of chronic inflammation, which impairs diastolic filling by compressing the cardiac chambers. Pericardiectomy is a promising surgical option for treating CP. In this study, we reviewed over 10 years of preoperative, perioperative, and short-term postoperative follow-ups of patients who underwent pericardiectomy for constrictive pericarditis at our clinic.

Background: The objective of the study was to compare drug-coated balloon (DCB) angioplasty alone and directional atherectomy (DA) combined with DCB angioplasty in patients with lower extremity peripheral arterial disease (LE-PAD).

Methods: Subjects treated with DCB angioplasty alone (group A) and DA combined with DCB angioplasty (group B) were enrolled in the study. A retrospective chart review was performed between the 4 years.

Vein of Galen aneurysmal malformation (VGAM) is a rare foetal anomaly associated with neurodevelopment delay, cardiac failure, and even perinatal death. We aimed to assess prenatal features of VGAM and describe postnatal outcomes. This was a retrospective study involving six foetuses diagnosed with VGAM prenatally in two centres.

Aims: Thromboxane (TxA) is synthesized from arachidonic acid (AA) via thromboxane synthase (TxS) enzyme and induces vasoconstriction via TP receptor. Our aim is to compare the effects of aspirin, TxS inhibitor and TP receptor antagonist on vascular reactivity of bypass grafts (saphenous vein and internal mammary artery).

Main Methods: Using isolated organ bath, saphenous vein and internal mammary artery preparations were incubated with TP receptor antagonist, TxS inhibitor, aspirin, IP or EP4 receptor antagonist.

As the COVID-19 pandemic continues, case reports have been published where patients with severe asthma using biological agents survived with a mild course of illness and encouraged the continuation of biological therapies in patients with severe asthma. However, contrary to previous information, a more severe course of COVID-19 has recently been reported in severe asthmatics using biological therapy compared to the general population. To evaluate the COVID-19 rate and disease severity in severe asthmatics using biological agents.

Antibiotic hypersensitivity reactions can lead to marked morbidity, mortality and inadequate treatment options. Mycobacterium abscessus infection is a difficult management system for clinicians since it most commonly involves the lungs, progresses if untreated, and the organism is resistant to many antibiotics, as well as the agents used in treatment can cause undesirable side effects. Although macrolides are one of the most reliable antibiotic groups in terms of allergic reactions, early type hypersensitivity reactions against macrolides, one of the main antibiotics used in the treatment of Mycobacterium abscessus lung disease, may make the treatment management of the disease difficult.

Background: Vasospasm and atherosclerosis due to low endothelial capacity are the most important causes of coronary artery bypass graft failure observed in internal mammary artery (IMA) and saphenous vein (SV). Vasospasm can be mimicked in in-vitro studies by inducing vasoconstriction of graft materials. In the present study, we aimed to compare the vascular contraction induced by several spasmogens including prostaglandin E2 (PGE2), prostaglandin F2 alpha (PGF), phenylephrine (PE), leukotriene C4 (LTC4), LTD4, potassium chloride (KCl), and arachidonic acid between IMA and SV preparations.

Background: Allergen immunotherapy (AIT) must be continued for 3 years, to achieve a long-term modifying effect. Adherence is a key to ensure effectiveness. The objective of this study was, first of all, to evaluate the adherence with subcutaneous immunotherapy (SCIT) and to identify the main causes of SCIT withdrawal in real-life practice in our clinic.

Objective: To compare the use of high saphenous ligation and stripping, radiofrequency ablation, and subfascial endoscopic perforator surgery for the treatment of active venous ulcers.

Methods: One hundred ninety-five ( = 195) subjects who were treated for venous leg ulcers were enrolled between 2009 and 2014. Three groups were formed (Group A: high saphenous ligation and total stripping, Group B: radiofrequency ablation of the great saphenous vein + perforators, and Group C: radiofrequency ablation of the great saphenous vein + subfascial endoscopic perforator surgery) ( = 65 for each group).

There is a lack of information about the course of coronavirus disease 2019 (COVID-19) in patients with severe asthma who were treated with biologics. Some reports indicated that treatment with benralizumab, dupilumab, and omalizumab in patients with severe asthma was not associated with significant adverse effects during COVID-19. Asthma itself or the biologic agents used to treat asthma can have a positive effect on the course of COVID-19.
