Recent studies have indicated that ceramide generated in the liver is secreted into the bloodstream as component of very-low-density lipoproteins (VLDL) and low-density lipoproteins (LDL). This manuscript investigates the effect of host acute phase response to inflammation on lipoprotein ceramide levels. In humans, two different patterns of responses were found. One group of volunteers experienced transient increases in serum ceramide at 1.5h after LPS administration. Second group showed prolonged increases that reached up to 10-fold above the basal level and continued for up to 24h. Increases in ceramide were found only in VLDL and LDL particles. LPS administration induced similar increases in mice. These increases were accompanied by activation of secreted sphingomyelinase in serum and serine-palmitoyl transferase in liver. ASMase knockout mice retained LPS-induced increases in serum ceramide, thus suggesting that the elevation of VLDL and LDL ceramide content is attributed at least in part to activation of de novo synthesis of ceramide in the liver.

Background: The long-term effects of COVID-19, which can vary significantly in type and timing, are considered relevant and impacting on the well-being of individuals. The present study aims to assess the incidence of outpatient care in the post-acute phase of SARS-CoV-2 infection in two Italian regions.
Methods: The study has a multicentre, population-based, pre-post, repeated measures design to compare the incidence rate of access to outpatient visits and diagnostics before and after SARS-CoV-2 infection, considering a follow-up of 24 months.

Background: SIREN is a healthcare worker cohort study aiming to determine COVID-19 incidence, duration of immunity and vaccine effectiveness across 135 NHS organisations in four UK nations. Conducting an intensive prospective cohort study during a pandemic was challenging. We designed an evolving retention programme, informed by emerging evidence on best practice.

Purpose: Myocardial injury, indicated by an elevation of high-sensitive cardiac Troponin (hs-cTnT), is a frequent stroke-related complication. Most studies investigated patients with ischemic stroke, but only little is known about its occurrence in patients with intracerebral hemorrhage (ICH). This study aimed to assess the frequency, predictors, and implications of myocardial injury in ICH patients.

Vertebroplasty has shown excellent analgesic effects in patients with osteoporotic vertebral fractures. In Japan, percutaneous vertebroplasty, balloon kyphoplasty, and vertebral body stenting are commonly performed. All of these techniques require precise transpedicular vertebral puncture and complete cement filling without leakage.

Acovenoside A, a cardenolide glycoside from Acokanthera oppositifolia, demonstrates significant therapeutic potential in cardioprotection and oncology, particularly against non-small cell lung cancer (NSCLC). However, its toxicological profile requires thorough evaluation for safe pharmaceutical application. For this purpose a comprehensive in silico methods were applied, including ACD/Labs Percepta, STopTox, admetSAR 3.
