Purpose: To evaluate the effect of corticosteroids on intestinal and liver interleukin profile in an experimental model of gastroschisis in fetal rats.
Methods: Sprague-Dawley rats at 19.5 days of gestation had its fetuses operated for the creation of gastroschisis. Two groups of fetuses were studied with and without maternal administration of dexamethasone. Each group was composed of fetuses who underwent gastroschisis (G), control fetuses without manipulation (C) and sham fetuses (S). A dosage of the following interleukins was carried out in fetal intestinal and liver tissues: IL-1, IL-6, IL-10, tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ). The differences between the groups and subgroups were tested by ANOVA with Tukey post-test, with significant values of p<0.05.
Results: Dexamethasone led to an increase in intestinal and liver IL-6 (p<0.05) and a decrease in intestinal TNF-α (p<0.001) in fetuses with gastroschisis.
Conclusion: Corticosteroids had an effect on the intestinal interleukin profile and a small effect on the liver interleukin profile due to immunological immaturity of the fetus, and also of fetuses with gastroschisis. The steroid action may not be exclusively anti-inflammatory, but also pro-inflammatory, varying with time of pregnancy.

Aortic regurgitation (AR) is more prevalent in male, although cellular and molecular mechanisms underlying the sex differences in prevalence and pathophysiology are unknown. This study evaluates the impact of sex on aortic valve (AV) inflammation and remodeling as well as the cellular differences in valvular interstitial cells (VICs) and valvular endothelial cells (VECs) in patients with AR. A total of 144 patients (27.

The effect of a mucilage extracted from Opuntia ficus-indica (L.) Mill (OFI) cladodes was tested in lipopolysaccharide (LPS)-challenged HepG2 hepatocarcinoma cells, through a combined in vitro-in silico approach. The OFI mucilage was characterized by gas chromatography-mass spectrometry and liquid chromatography-high resolution mass spectrometry.

Aim: Sympathetic overactivation may lead to severe ventricular arrhythmias (VAs) post-myocardial infarction (MI). The superior cervical ganglion (SCG) is an extracardiac sympathetic ganglion which regulates cardiac autonomic tone. We aimed to investigate the characteristics and functional significance of SCG on neuro-cardiac communication post-MI.

Objective: Based on the findings of the KEYNOTE-048 study, pembrolizumab in combination with platinum and fluorouracil is the standard first-line treatment for recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). The efficacy and safety of pembrolizumab combined with nab-paclitaxel and platinum in such patients remain unexplored.
Methods: This single-arm phase 2 study enrolled patients with R/M HNSCC who received pembrolizumab (200 mg), nab-paclitaxel (260 mg/m²), and either cisplatin (75 mg/m²) or carboplatin [area under the curve (AUC) 5] every 21 d for up to six cycles, followed by pembrolizumab maintenance therapy.
