Magnetic resonance-conditional cardiac implantable electronic devices: an Italian perspective on the prevalence of mixed-brand systems over time.

The historical restriction of magnetic resonance imaging (MRI) for patients with cardiac implantable electronic devices (CIEDs) has been lifted by certified MRI-conditional systems in recent years. Mixed-brand CIED systems consisting of a generator from one manufacturer and at least one lead from another manufacturer are not certified for MRI. We evaluated the temporal trend in the prevalence of mixed-brand systems in the era of MRI-conditional systems.

Interventricular Septal Hematoma Complicating Left Bundle Branch Area Pacing: A Case Report-The Devil Is Not So Black as He Is Painted.

Background: This case report outlines the presentation of an emerging complication arising from left bundle branch area pacing (LBBAP).

Case Summary: A 43-year-old male with no history of cardiac problems experienced recurrent episodes of syncope with no prodromal symptoms. During monitoring in the emergency department, the patient underwent an episode of asystole, leading to LBBAP implantation.

Age-related increases in cardiac excitability, refractoriness and impulse conduction favor arrhythmogenesis in male rats.

The effects of excitability, refractoriness, and impulse conduction have been independently related to enhanced arrhythmias in the aged myocardium in experimental and clinical studies. However, their combined arrhythmic effects in the elderly are not yet completely understood. Hence, the aim of the present work is to relate relevant cardiac electrophysiological parameters to enhanced arrhythmia vulnerability in the in vivo senescent heart.

Thermal Requirements of (Hym.: Encyrtidae) and (Hym.: Platygastridae) Parasitizing Eggs (Hem.: Pentatomidae).

Temperature is one of the abiotic factors that strongly influences the biology and behavior of insects. In this study, we assessed the development of egg parasitoids and parasitizing eggs at different temperatures, and estimated the average number of generations for seven representative soybean-producing regions in Brazil. A comparative biology study was conducted, where the percentage of parasitism and emergence, life cycle duration (egg-adult), and longevity were found to be similar between and .

Do fall armyworm's Metaflumizone resistante populations affect the activity of Trichogramma pretiosum?

The possible interference of resistant pest's populations to insecticides in natural enemies in the action thas not been clarified yet. Thus, this study aimed to evaluate Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) performance on Spodoptera frugiperda (J. E.
