Rapid Assessment of COVID-19 Screening Program for Travelers in Iran: A Qualitative Study
2022
AbstractObjective:Coronavirus disease 2019 (COVID-19) screening stations set up by Iranian Red Crescent Society have been available for 17 d with the aim of identifying and treating people with coronavirus, reducing road trips, and sensitizing people to the problem. This study aims to investigate the challenges of the procedure.Methods:A qualitative study was used to find the challenges of the COVID-19 screening centers. Volunteers, branch managers, and headquarter managers of the Iranian Red Crescent Society participated in this study applying snowball sampling. Data were collected by means of in-depth semi-structured telephone interviews in April 2020 after completion of the fever screeni…
Renin-Angiotensin System Blockade and Mortality in Patients With Hypertension and COVID-19 Infection
2020
To determine the effect renin-angiotensin system blockers on the outcome in patients with hypertension and concurrent COVID-19 infection, we searched PubMed, the Cochrane Library, and Google Scholar for relevant articles. Twelve studies with a total of 16,101 patients met the inclusion criteria. The mortality rate among the users of angiotensin converting enzyme inhibitors or angiotensin receptor blockers was 12.15% and in non-users it was 14.56% (risk ratio 0.70, 95% CI [0.53-0.91], P < 0.007). There was no difference in the risk of death between the use of angiotensin converting enzyme inhibitors and angiotensin receptor blockers (risk ratio 1.09, 95% CI [0.90 -1.32]). We conclude tha…
Association between frontal plane knee control and lower extremity injuries : a prospective study on young team sport athletes
2017
Background/aimPoor frontal plane knee control can manifest as increased dynamic knee valgus during athletic tasks. The purpose of this study was to investigate the association between frontal plane knee control and the risk of acute lower extremity injuries. In addition, we wanted to study if the single-leg squat (SLS) test can be used as a screening tool to identify athletes with an increased injury risk.MethodsA total of 306 basketball and floorball players participated in the baseline SLS test and a 12-month injury registration follow-up. Acute lower extremity time-loss injuries were registered. Frontal plane knee projection angles (FPKPA) during the SLS were calculated using a two-dimen…
Medical therapy or revascularization for patients with chronic total occlusion? A dilemma almost solved
2020
Chronic total occlusion (CTO) of the coronary arteries are relatively common, observed in approximatively 15-25% of patients with coronary artery disease undergoing coronary angiography. The right coronary artery represents the most common CTO vessel, which represents about half of the CTO cases.The CTO prevalence is much higher ( 90%) among patients with prior coronary artery bypass graft (CABG), while a CTO is found in only one tenth of patients referred for ST-elevation myocardial infarction (STEMI)
Clinical Characteristics, Treatments, and Outcomes of Patients with Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA): Results fr…
2020
Background: Diagnosis of myocardial infarction with non-obstructive coronary arteries (MINOCA) requires both clinical evidence of acute myocardial infarction (AMI) and demonstration of non-obstructive coronary arteries using angiography. We compared the clinical features, treatments, and three-year outcomes in patients with MINOCA and myocardial infarction with obstructive coronary artery disease (MI-CAD). Methods: We retrospectively analyzed data for 205,606 hospitalized patients with AMI. MINOCA was indicated as a working diagnosis in 6063 patients (2.94% of all AMI patients). For the control group we included 160,886 patients with MI-CAD. We evaluated the baseline characteristics, medica…
The Multifaceted Interplay between Atrial Fibrillation and Myocardial Infarction: A Review
2021
International audience; This review was conducted to emphasize the complex interplay between atrial fibrillation (AF) and myocardial infraction (MI). In type 1 (T1) MI, AF is frequent and associated with excess mortality. Moreover, AF after hospital discharge for T1MI is not rare, suggesting the need to improve AF screening and to develop therapeutic strategies for AF recurrence. Additionally, AF is a common trigger for type 2 MI (T2MI), and recent data have shown that tachyarrhythmia or bradyarrhythmia could be a causal factor in, respectively, 13–47% or 2–7% of T2MI. In addition, AF is involved in T2MI pathogenesis as a result of severe anemia related to anticoagulants. AF is also an unde…

CT-Angiographie an einem 16-Schicht-CT zur perioperativen Evaluation der Leberarterien im Vergleich zur MR-Angiographie
2004
Purpose: To evaluate the efficiency of CT angiography (CTA) with 16-row MSCT compared with MR angiography (MRA) in analyzing the arterial anatomy in patients undergoing liver surgery. Materials and Methods: In 30 patients, MRA and CTA studies of the abdominal vessels were reviewed. CT parameters: slice thickness 3 mm; collimation 1.5; reconstruction interval 2 mm (Philips MX 8000 IDT); 120 ml contrast media (400 mg/ml) at a rate of 4 ml/ sec; acquisition of arterial-phase scans. The anatomy of the hepatic artery was evaluated from axial and reconstructed maximum-intensity-projection (MIP) images ("Slab-Viewer", Philips). MR parameters: contrast-enhanced coronal FLASH-3D sequences; slice thi…
An FFR CT diagnostic strategy versus usual care in patients with suspected coronary artery disease planned for invasive coronary angiography at Germa…
2017
Aim Diagnostic evaluation practices for suspected coronary artery disease (CAD) may vary between countries. Our objective was to compare a CT-derived fractional flow reserve (FFRCT) diagnostic strategy with usual care in patients with planned invasive coronary angiography (ICA) enrolled in the PLATFORM (Prospective Longitudinal Trial of FFRCT: Outcome and Resource Impacts) study at German sites. Methods Patients were divided into two consecutive observational cohorts, receiving either usual care or CT angiography (CTA)/FFRCT. The primary endpoint was the percentage of patients planned for ICA, with no obstructive CAD on ICA within 90 days. Secondary endpoints included death, myocardial infa…
