Purpose: The objective of this study is to evaluate the right ventricular ejection fraction (RVEF) during orthotopic liver transplantation (OLT) under 2 different anesthetic regimens: propofol vs isoflurane anesthesia.
Methods: We retrospectively analyzed the hemodynamic data of 25 (n = 25) patients who underwent OLT during the last year (2008). All patients were monitored with a modified pulmonary artery catheter, which continuously measured the RVEF. Anesthetic technique consisted of either isoflurane or total intravenous anesthesia with propofol. Surgical technique was similar between groups.
Results: Ten (n = 10) patients comprised the isoflurane group (I), whereas 15 (n = 15) patients received propofol anesthesia (P). The RVEF was not significantly different between groups (I vs P, baseline: 41% ± 9% vs 40% ± 6%; anhepatic phase: 36% ± 8% vs 35% ± 6%; postreperfusion: 41% ± 6% vs 41% ± 8%; P = not significant).
Conclusions: The choice between propofol and isoflurane seems to have minimal influence on the RVEF during OLT, which followed similar trends regardless of the anesthetic technique.

Control values of intraocular pressure in different species: a review of literature.

It is generally accepted that intraocular pressure (IOP) depends on the rate of aqueous humor production, system outflow resistance, and episcleral venous pressure. Therefore, control IOP values are expected to be within the strict and predictable limits in specific animal species, and there should be no vast differences between species. However, in the literature the control IOP values significantly vary (from potentially "hypotensive" to "hypertensive") within the same species, and especially between species depending on the measurement technique, head position in relation to the rest of the body, circadian rhythm, age, and topical and systemic drugs (anesthetics) applied.

Platelets, tiny cell fragments measuring 2-4 μm in diameter without a nucleus, play a crucial role in blood clotting and maintaining vascular integrity. Abnormalities in platelets, whether genetic or acquired, are linked to bleeding disorders, increased risk of blood clots, and cardiovascular diseases. Advanced proteomic techniques offer profound insights into the roles of platelets in hemostasis and their involvement in processes such as inflammation, metastasis, and thrombosis.

Background: Early-onset ischemic heart disease (IHD) is a growing burden associated with high disability and death.
Objectives: This study aimed to estimate the burden of incidence, prevalence, and disability-adjusted life years (DALY) of early-onset IHD from 1990 to 2019.
Methods: Data on the burden of early-onset IHD (men<55 years, women<65 years), including prevalence, incidence, DALY, and deaths, were collected from the Global Burden of Disease study for 204 countries and territories from 1990 to 2019.
