"Evaluating the efficacy and safety of direct oral anticoagulants compared to warfarin in very morbidly obese patients with non-valvular atrial fibrillation: A retrospective cohort study".

•DOACs are effective and safe in very morbidly obese AF patients (BMI ≥50 kg/m).•DOACs show similar stroke and bleeding risks as warfarin in this population.•Findings support DOACs in anticoagulation guidelines for very morbidly obese patients.

Reconfigured single- and double-diode models for improved modelling of solar cells/modules.

Proper modeling of PV cells/modules through parameter identification based on the real current-voltage (I-V) data is important for the efficiency of PV systems. Most related works have concentrated on the classical single-diode model (SDM) and double-diode model (DDM) and their parameter extraction by various metaheuristic algorithms. In order to render more accurate and representative modeling, this paper adds a small resistance in series with the diodes in SDM and DDM.

Effect of trimetazidine on left ventricular functions and cardiac biomarkers in diabetic patients with left ventricular diastolic dysfunction: a randomized controlled trial.

We investigated the impact of trimetazidine treatment on left ventricular (LV) functions and cardiac biomarkers in diabetic patients with diastolic dysfunction as an early stage of diabetic cardiomyopathy. Sixty-three patients were randomly assigned to receive either trimetazidine or a placebo for 3 months. At baseline and after 3-months of treatment, measurements of serum levels of glycemic control parameters, lipid profile, tumor necrosis factor alpha, transforming growth factor beta 1, n-terminal pro brain natriuretic peptide and assessment of modified Medical Research Council (mMRC) dyspnea score, echocardiographic indices of LV functions and LV global longitudinal strain (GLS) were performed.
