Evaluation of hemodialysis patients and hemodialysis health workers with COVID-19 IgM and IgG antibody test; a multicenter study from Eskisehir, Turkiye.

Objective: Hemodialysis (HD) patients are a population at high risk for exposure to the severe respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. Undiagnosed mild or asymptomatic SARS-CoV-2 infection in HD patients can make these patients a potential source of infection. In our study, we aimed to evaluate the entire spectrum of SARS-CoV-2 infection with the IgM and IgG rapid antibody kit in HD patients and healthcare providers working in HD unit.

Serum ADMA, endothelial dysfunction, and atherosclerosis in hypervolemic hemodialysis patients.

Background/aim: Asymmetric dimethyl arginine (ADMA) is a strong predictor of cardiovascular disease and mortality in patients under hemodialysis treatment. We aimed to investigate the relationship among volume status, endothelial dysfunction, and ADMA in hemodialysis patients. Materials and methods: A total of 120 patients with a history of hemodialysis treatment were included.

Surgical approach for Stanford type A aortic dissection in a patient with Marfan syndrome and pectus excavatum.

Acute Stanford type A aortic dissection in a patient with severe pectus excavatum constitutes a surgical emergency and presents a major challenge for the surgeon. Decisions must be made regarding the operative approach and whether the pectus excavatum should be corrected during the same session. Herein, we describe a case of acute aortic dissection in a patient who had Marfan syndrome with severe pectus excavatum.

Effects of pretreatment with different topical vasodilators on blood flow in the internal mammary artery: a prospective randomized study.

Background: This study was conducted to investigate how brief pretreatments with 4 different vasodilators applied topically at normal body temperature affect blood flow in the internal mammary artery.

Methods: One hundred patients who had an internal mammary artery mobilized as a pedicle for coronary artery bypass grafting were randomly assigned to one of 5 groups of equal size (20 subjects in each). Each group of pedicles was treated with a different topical solution: normal saline (control), nitroglycerin, diltiazem, papaverine, or adenosine.

Topical vasodilators for preventing radial artery spasm during harvesting for coronary revascularization: comparison of 4 agents.

Background: There is still controversy about which vasodilator solution is best for storing radial artery (RA) conduits prior to coronary artery bypass grafting. The aim of this pilot study was to investigate how 4 different topical vasodilators applied during RA harvesting affect blood flow with the vessel in situ.

Materials And Methods: The subjects were 85 patients who underwent RA harvesting in preparation for coronary artery bypass grafting.
