Atrial fibrillation (AF) is the most common arrhythmia with adverse clinical outcomes. Aortic valve replacement (AVR) is one of the most frequently performed cardiac surgeries, although there is scarce evidence on arrhythmic outcomes. We aimed to evaluate AF during the first year post- isolated aortic valve replacement surgery and its clinical, analytical, and echocardiographic predictors.
Severe aortic stenosis patients with no prior atrial fibrillation submitted to isolated aortic valve replacement surgery were included in our study, of which 316 remained in sinus rhythm and 24 developed AF. We performed logistic regression searching for AF predictors and a longitudinal comparison between pre and post-operative echocardiographic data.
Postoperative AF (POAF), diabetes, and follow-up indexed Left Atrium Diameter (iLAD) were significantly higher in the group of patients developing AF. POAF and iLAD were independent AF predictors at follow-up. No differences between groups were found regarding baseline and follow-up echocardiographic data except for indexed Left Ventricle End-diastolic Diameter (LVED), which failed to decrease after surgery in the AF group.
POAF and iLAD independently predicted AF at 1 year following isolated AVR surgery in aortic stenosis patients with no AF history. iLVED did not decrease significantly at follow-up in AF patients, possibly reflecting adverse ventricular remodeling.

The aim of this research was to use the Mehran risk score to classify elderly diabetics with coronary heart disease to assess the preventive effect of trimetazidine on contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI) in different risk population.
An uncompromised of 760 elderly diabetics that went through PCI were included in this research. The patients were first divided into three groups in the light of MRS low-risk, moderate-risk, and high-risk group, then randomized into trimetazidine group and the control group respectively. Poly-D-lysine supplier The first endpoint was the amount of CIN, which is described as a rise in serum creatinine levels by ⩾44.2 μmol/L or ⩾25% ratio within 48 or 72 hours after medication. Second endpoint included differences in creatinine clearance rate (CrCl), blood urea nitrogen (BUN), serum creatinine (Scr), cystatin-C (Cys-C), and the incidence of major adverse events after administration.
In the three groups, the incidence of CIN in trimetazidine and control group was 5.0% versus 4.9%(χ
 = 0.005, p > 0.05), 8.0% versus 18.0% (χ
 = 7.685, p < 0.05), 10.4% versus 27.1% (χ
 = 4.376, p < 0.05), respectively. The multivariable logistic regression result demonstrated that trimetazidine intervention was a profitable element of CIN in moderate and high-risk groups (OR = 0.294, 95% CI 0.094-0.920, p = 0.035).
Our study confirmed that trimetazidine can be considered for preventive treatment of CIN occurrence in elderly diabetics with moderate and high-risk population, while there is no obvious advantage compared with hydration therapy in low-risk patients.

We applied a bioinformatics approach using molecular dynamics and docking to identify FDA-approved drugs that can be re-purposed to potentially inhibit the non-structural protein 9 (Nsp9) replicase and spike proteins in SARS-CoV-2. We performed virtual screening of FDA-approved compounds, including antiviral, anti-malarial, anti-parasitic, anti-fungal, anti-tuberculosis, and active phytochemicals against the Nsp9 replicase and spike proteins. Selected hit compounds were identified based on their highest binding energy and favorable absorption, distribution, metabolism and excretion (ADME) profile. Conivaptan, an arginine vasopressin antagonist drug exhibited the highest binding energy (-8.4 Kcal/mol) and maximum stability with the amino acid residues present at the active site of the Nsp9 replicase. Tegobuvir, a non-nucleoside inhibitor of the hepatitis C virus, also exhibited maximum stability along with the highest binding energy (-8.1 Kcal/mol) at the active site of the spike proteins. Molecular docking scores were further validated by molecular dynamics using Schrodinger, which supported the strong stability of ligands with the proteins at their active sites through water bridges, hydrophobic interactions, and H-bonding. Our findings suggest Conivaptan and Tegobuvir as potential therapeutic agents against SARS-CoV-2. Further in vitro and in vivo validation and evaluation are warranted to establish how these drug compounds target the Nsp9 replicase and spike proteins.
Education regarding death diagnosis is not often included in the medical education.
To investigate the change minds at the time of death diagnosis among residents after lectures based on our guidebook.
Uncontrolled, open-label, multi-center trial.
A total of 131 doctors undergoing their initial training were enrolled this study.
Questionnaires were administered to volunteers before and after the lecture by the clinical training instructor presented information regarding doctors' behaviors at the death diagnosis based on our guidebook at each hospital.
The subjects had an average age of 27.1 years and comprised 76 men (58.0%) and 54 women (41.2%). A total of 83 subjects (63.4%) had learned how to diagnose death as medical students, and 52 subjects (39.7%) had experienced death diagnosis scenes as medical students. Among those who had difficulties related to death diagnoses, the highest number (88.4%) indicated that "I do not know what to say to the family after a death diagnosis". Self-evaluation significantly increased after the lecture for many items concerning explanations to and considerations of the family the effect size for "Give words of comfort and encouragement to family" increased significantly after the lecture to 0.
