Percutaneous Treatment of Left Main Coronary Artery Ostial Stenosis After Bentall Operation.

Iatrogenic coronary ostial stenosis (ICOS) is a rare but life-threatening complication of aortic root surgery. It can occur with the incidence of 0.3%-5% and affect more commonly the left main coronary artery (LMCA) compared to the right coronary artery (RCA).

A New Class of Polyion Complex Vesicles (PIC-somes) to Improve Antimicrobial Activity of Tobramycin in Pseudomonas Aeruginosa Biofilms.

Pseudomonas aeruginosa (PA) is a major healthcare concern due to its tolerance to antibiotics when enclosed in biofilms. Tobramycin (Tob), an effective cationic aminoglycoside antibiotic against planktonic PA, loses potency within PA biofilms due to hindered diffusion caused by interactions with anionic biofilm components. Loading Tob into nano-carriers can enhance its biofilm efficacy by shielding its charge.

A machine learning analysis of predictors of future hypertension in a young population.

Background: Early diagnosis of hypertension (HT) is crucial for preventing end-organ damage. This study aims to identify the risk factors for future HT in young individuals through the application of machine learning (ML) models.

Methods: The study included individuals aged 18-40 years who had not been diagnosed with HT through ambulatory blood pressure monitoring (ABPM).

Prolongation of QTc interval due to increased parity and great grand multiparity.

Women are more prone to cardiac arrhythmias. Increased exposure to sex hormones may alter the ventricular repolarisation of the heart as the parity number increases. In this study, we aim to investigate the effect of parity number to electrocardiographic parameters.

The atherogenic index of plasma as a predictor of mortality in patients with COVID-19.

Background: Coronavirus disease 2019 (COVID-19) has become a global health threat, and thus, an early and effective set of predictors is needed to manage the course of the disease.

Objectives: We aim to determine the effect of SARS-CoV-2 on lipid profile and to evaluate whether the atherogenic index of plasma (AIP) could be used to predict in-hospital mortality in COVID-19 patients.

Methods: In this retrospective chart review study, a total of 139 confirmed COVID-19 patients, whose diagnoses are confirmed by PCR and computerized tomography results, are enrolled.

Size-controlled clustering of iron oxide nanoparticles within fluorescent nanogels using LCST-driven self-assembly.

Size-controlled clustering of iron oxide nanoparticles (IONPs) within the fluorescent polymer nanogels was achieved using the lower critical solution temperature (LCST) driven self-assembly and cross-linking of grafted polymer on the IONPs. The grafted polymer was comprised of oligoethyleneglycol methacrylate (OEGMA) and a novel dichloromaleimide functional methacrylate monomer as building blocks. As a result of the temperature responsive behavior of OEGMA, polymer grafted IONPs clustered to form larger nano-sized aggregates when heated above the LCST of the polymer.

Evaluation of the Tp-e interval and Tp-e/QTc ratio in patients with benign paroxysmal positional vertigo in the emergency department compared with the normal population.

Introduction: Benign paroxysmal positional vertigo (BPPV) is a common diagnosis for dizziness patients admitting to emergency department and for initial diagnosis, cardiac causes of dizziness should be excluded at admittance. Electrocardiography (ECG) is a simple method to detect cardiac arrhythmias for these patients. Tp-e interval and Tp-e/QTc ratio are transmural repolarization parameters and shown to be strongly related to ventricular arrhythmias.

Transient ST Segment Elevation Caused by Intracoronary Thrombus after Acute Carbon Monoxide Poisoning.

Carbon monoxide (CO) poisoning is the most common cause of death and injury among all poisonings. Myocardial injury is detected in one-third of CO poisonings. In this Case Report, a previously healthy 41-year-old man was referred for CO poisoning.

Short term follow-up of a patient with uncomplicated type B aortic dissection under dabigatran treatment.

This case report illustrates the follow-up of a 57-year-old female with a type B aortic dissection (AD) under dabigatran treatment. The patient had been operated on 8 years earlier due to type A AD. The aortic valve was repaired and a 26-mm polyester fiber graft was applied to the ascending aorta and the aortic arch.
