    Association between renin-angiotensin-aldosterone system inhibitor treatment, neutrophil-lymphocyte ratio, D-Dimer and clinical severity of COVID-19 in hospitalized patients: a multicenter, observational study
    (SPRINGERNATURE, 2021-01-01) Gormez, Selcuk; Ekicibasi, Erkan; Degirmencioglu, Aleks; Paudel, Ashok; Erdim, Refik; Gumusel, Hilal Kurtoglu; Eroglu, Elif; Tanboga, Ibrahim Halil; Dagdelen, Sinan; Sariguzel, Nevin; Kirisoglu, Ceyda Erel; Pamukcu, Burak
    The aim of this study was to investigate the possible relationship between worse clinical outcomes and the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in hospitalized COVID-19 patients. A total of 247 adult patients (154 males, 93 females

    Background: Radial artery occlusion (RAO) is an infrequent complication of transradial coronary procedures (TRA). To our knowledge, there is no satisfactory data regarding the late term incidence and predictors of RAO in the literature. Our aim was to establish the long-term incidence of radial artery occlusion and investigate its predictors. Methods: This was a single center prospective study. A total number of 409 consecutive patients undergoing their first TRA were recruited. Clinical and procedural data were all recorded. Doppler ultrasound examination was performed at 6-15 months following the intervention. Results: RAO was detected in 67 patients and 342 patients maintained radial artery patency. The overall RAO incidence was 16.4\% at late term. Patients with RAO were younger than the patients with patent radial arteries (55.9 +/- 9.7 vs. 59.1 +/- 9.4 years, p = 0.014). The incidence of RAO in hypertensive patients (9.8\%) was lower (p < 0.001) than the observed incidence (23\%) in non-hypertensive patients. RAO group had higher rate (28\%, p = 0.027) of post-procedural access site pain. Regression analysis revealed that hypertension was negative while post-procedural access site pain was positive independent predictors for RAO. In addition, the relative risk for RAO also increased significantly (p < 0.001) when the ratio of sheath/artery diameter (S/A) was > 1. Conclusions: The present study reveals that the long-term incidence of RAO is 16.4\%. Hypertension, post-procedural access site pain and S/A ratio > 1 are independent predictors of RAO at late term.

    Is the Nexfin finger cuff method for cardiac output measurement reliable during coronary artery bypass grafting? A prospective comparison with the echocardiography and FloTrac/Vigileo methods
    (TUBITAK SCIENTIFIC \& TECHNICAL RESEARCH COUNCIL TURKEY, 2016-01-01) Ariturk, Cem; Acil, Meltem; Ulugol, Halim; Ozgen, Zehra Serpil Ustalar; Okten, Eyup Murat; Dagdelen, Sinan; Karabulut, Esref Hasan; Alhan, Huseyin Cem; Toraman, Fevzi
    Background/aim: The aim of the current study was to assess the accuracy of cardiac output (CO) measurements obtained by the Nexfin finger cuff method as compared with the FloTrac/Vigileo and echocardiography methods in coronary artery bypass grafting (CABG) patients. Materials and methods: First-time elective CABG patients were prospectively enrolled in this study and divided into three groups according to CO measurement method. CO measurements were performed simultaneously by three different contributors and were collected by the fourth one 24 h postoperative in the intensive care unit (ICU). Data were statistically analyzed. Results: Seventeen female and 13 male patients between 42 and 78 years of age (with a mean of 56 +/- 4) were the subjects of this study. The mean CO measurements were 5.9 +/- 1.4 L/min, 5.8 +/- 1.1 L/min, and 6.0 +/- 1.1 L/min for the Nexfin, FloTrac/Vigileo, and echocardiography methods, respectively (P > 0.05). The correlation values between Nexfin and FloTrac/Vigileo, Nexfin and echocardiography, and FloTrac/Vigileo and echocardiography were r = 0.445, r = 0.377, and r = 0.384, respectively (P < 0.05). Conclusion: Nexfin yielded results comparable to those obtained with FloTrac/Vigileo and echocardiography for the postoperative CO assessment of CABG patients. Nexfin may be used in uncomplicated, hemodynamically stable patients in ICU as a reliable and totally noninvasive method of CO measurement.
