Safety and efficacy of dronedarone from clinical trials to real-world evidence: implications for its use in atrial fibrillation.

Efficacy and safety of dronedarone was shown in the ATHENA trial for paroxysmal or persistent atrial fibrillation (AF) patients. Further trials revealed safety concerns in patients with heart failure and permanent AF. This review summarizes insights from recent real-world studies and meta-analyses, including reports on efficacy, with focus on liver safety, mortality risk in patients with paroxysmal/persistent AF, and interactions of dronedarone with direct oral anticoagulants. Reports of rapidly progressing liver failure in dronedarone-prescribed patients in 2011 led to regulatory cautions about potential liver toxicity. Recent real-world evidence suggests dronedarone liver safety profile is similar to other antiarrhythmics and liver toxicity could be equally common with many Class III antiarrhythmics. Dronedarone safety concerns (increased mortality in patients with permanent AF) were raised based on randomized controlled trials (RCT) (ANDROMEDA and PALLAS), but comedication with digoxin may have increased the mortality rates in PALLAS, considering the dronedarone-digoxin pharmacokinetic (PK) interaction. Real-world data on apixaban-dronedarone interactions and edoxaban RCT observations suggest no significant safety risks for these drug combinations. Median trough plasma concentrations of dabigatran 110 mg during concomitant use with dronedarone are at acceptable levels, while PK data on the rivaroxaban-dronedarone interaction are unavailable. In RCTs and real-world studies, dronedarone significantly reduces AF burden and cardiovascular hospitalizations, and demonstrates a low risk for proarrhythmia in patients with paroxysmal or persistent AF. The concerns on liver safety must be balanced against the significant reduction in hospitalizations in patients with non-permanent AF and low risk for proarrhythmias following dronedarone treatment

The influence of progression of atrial fibrillation on quality of life: a report from the Euro Heart Survey.

Aims: Progression of atrial fibrillation (AF) from paroxysmal to persistent forms is an active field of research. The influence of AF progression on health related quality of life (HRQoL) is currently unknown. We aimed to assess the influence of AF progression on HRQoL, and whether this association is mediated through symptoms, treatment, and major adverse events. Methods and results: In the Euro Heart Survey, 967 patients were included with paroxysmal AF who filled out EuroQoL-5D at baseline and at 1 year follow-up. Those who progressed (n = 132, 13.6%) developed more problems during follow-up than those who did not, on all EuroQoL-5D domains (increase in problems on mobility 20.5% vs. 11.4%; self-care 12.9% vs. 6.2%; usual activities 23.5% vs. 14.0%; pain/discomfort 20.5% vs. 13.7%; and anxiety/depression 22.7% vs. 15.7%; all P < 0.05), leading to a decrease in utility [baseline 0.744 ± 0.26, follow-up 0.674 ± 0.36; difference -0.07 (95% CI [-0.126,-0.013], P = 0.02)]. Multivariate analysis showed that the effect of progression on utility is mediated by a large effect of adverse events [stroke (-0.27 (95% CI [-0.43,-0.11]); P = 0.001], heart failure [-0.12 (95% CI [-0.20,-0.05]); P = 0.001], malignancy (-0.31 (95% CI [-0.56,-0.05]); P = 0.02] or implantation of an implantable cardiac defibrillator [-0.12 (95% CI [-0.23,-0.02]); P = 0.03)], as well as symptomatic AF [-0.04 (95% CI [-0.08,-0.01]); P = 0.008]. Conclusion: AF progression is associated with a decrease in HRQoL. However, multivariate analysis revealed that AF progression itself does not have a negative effect on HRQoL, but that this effect can be attributed to a minor effect of the associated symptoms and a major effect of associated adverse events

Humoral immune response to different routes of myxomatosis vaccine application

[EN] The aim of our study was to monitor the dynamics of the serological response to different application routes of live attenuated myxomatosis vaccine. The study included 42 Californian breed rabbits, aged 3 mo, of both sexes. They were separated into 7 groups: 6 experimental and 1 control. All experimental groups were vaccinated on day 0 with a single dose of myxomatosis vaccine (min 103.3 tissue culture infective dose 50 [TCID50], max 105.8 TCID50). Three of the groups were injected with monovalent attenuated myxomatosis vaccine using different types of application: intradermal (i.d.), intramuscular (i.m.) and subcutaneous (s.c.). The other 3 groups were injected with bivalent attenuated vaccine against myxomatosis and rabbit haemorrhagic disease; again the routes of administration were i.d., i.m. and s.c.. There were no clinical signs or serious side effects after vaccination. The serological response was evaluated on days 7, 15 and 30 with a monoclonal antibody based-competition enzyme-linked immunosorbent assay (cELISA). More rapid and potent humoral response was detected in groups with i.d. inoculation in comparison to i.m. and s.c. routes. Vaccination with monovalent vaccine against myxomatosis induced higher antibody titre in comparison to bivalent vaccine. Our study showed that the vaccine application route and the type of vaccine used influence the speed and intensity of antibody response.Manev, I.; Genova, K.; Lavazza, A.; Capucci, L. (2018).

In Car Audio

This chapter presents implementations of advanced in Car Audio Applications. The system is composed by three main different applications regarding the In Car listening and communication experience. Starting from a high level description of the algorithms, several implementations on different levels of hardware abstraction are presented, along with empirical results on both the design process undergone and the performance results achieved

On a fibrational construction for optics, lenses, and Dialectica categories

Categories of lenses/optics and Dialectica categories are both comprised of bidirectional morphisms of basically the same form. In this work, we show how they can be considered a special case of an overarching fibrational construction, generalizing Hofstra’s construction of Dialectica fibrations and Spivak’s construction of generalized lenses. This construction turns a tower of Grothendieck fibrations into another tower of fibrations by iteratively twisting each of the components, using the opposite fibration construction

A novel non-invasive device for the assessment of central venous pressure in hospital, office and home

Background: Venous congestion can be quantified by central venous pressure (CVP) and its monitoring is crucial to understand and follow the hemodynamic status of patients with cardio-respiratory diseases. The standard technique for CVP measurement is invasive, requiring the insertion of a catheter into a jugular vein, with potential complications. On the other hand, the current non-invasive methods, mainly based on ultrasounds, remain operator-dependent and are unsuitable for use in the home environment. In this paper, we will introduce a novel, non-invasive device for the hospital, office and home assessment of CVP. Methods: After describing the measurement concept, we will report a preliminary experimental study enrolling 5 voluntary healthy subjects to evaluate the VenCoM measurements’ repeatability, and the system’s capability in measuring small elicited venous pressure variations (2 mmHg), as well as an induced venous hypertension within a pathological range (12÷20 mmHg). Results: The experimental measurements showed a repeatability of ±1mmHg. The VenCoM device was able to reliably detect the elicited venous pressure variations and the simulated congestive status. Discussion and Conclusion: The proposed non-invasive VenCoM device is able to provide a fast and repeatable CVP estimate, having a wide spectrum of potential clinical applications, including the monitoring of venous congestion in heart failure patients and in subjects with renal and hepatic dysfunction, as well as pulmonary hypertension (PH) that can be extended to pneumonia COVID-19 patients even after recovery. The device needs to be tested further on a large sample size of both healthy and pathological subjects, to systematically validate its reliability and impact in clinical setting
