Objective: Antenatal corticosteroids (ACS) decrease respiratory distress syndrome in singleton gestations. Twin data are less clear. Obesity and body mass index (BMI) also affect medication distribution volume. We evaluated whether maternal or neonatal cord betamethasone concentrations differed in twin gestations or obese patients.

Study Design: Participants receiving betamethasone in a randomized controlled trial of weekly ACS were identified. We analyzed maternal delivery and cord serum betamethasone concentrations comparing singletons with twins and obese (BMI > or =30 kg/m(2)) with nonobese women.

Results: Fifty-five maternal and 45 cord blood samples were available. Unadjusted median maternal serum concentrations appeared paradoxically higher in both twin gestations and the obese. However, after controlling for confounders, there were no differences in betamethasone concentrations in maternal serum or cord blood between singletons and twins (P = .61 vs P = .14) or nonobese and obese women (P = .67 vs .12).

Conclusion: Maternal and umbilical cord blood serum betamethasone concentrations are not different in twin gestations or obese women.

Researchers have repurposed several existing anti-inflammatory drugs as potential antifungal agents in recent years. So, this study aimed to investigate the effects of anti-inflammatory drugs on the growth, biofilm formation, and expression of genes related to morphogenesis and pathogenesis in Candida albicans. The minimum inhibitory concentration (MIC) of anti-inflammatory drugs was assessed using the broth microdilution method.

Purpose: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease that severely impairs patient's life quality and represents significant therapeutic challenge due to its pathophysiology arising from skin barrier dysfunction. Topical corticosteroids, the mainstay treatment for mild to moderate AD, are usually formulated into conventional dosage forms that are impeded by low drug permeation, resulting in high doses with consequent adverse effects, and also lack properties that would strengthen the skin barrier. Herein, we aimed to develop biomimetic lamellar lyotropic liquid crystals (LLCs), offering a novel alternative to conventional AD treatment.

Glucocorticoids influence on rat hematological parameters and catalase activity.

Front Pharmacol

Department of Biology, Faculty of Science, University of Sarajevo, Sarajevo, Bosnia and Herzegovina.

In this study, the impact of glucocorticoid, betamethasone dipropionate on enzyme activity and its effects on hematological parameters was investigated. The immobilized catalase, crucial for cell oxidative stress response via hydrogen peroxide reduction, exhibited a robust electrocatalytic response, maintaining its biological activity. The inhibition kinetics of catalase, as determined by electrocatalytic methods and expressed using Lineweaver-Burke diagrams, revealed an uncompetitive type of inhibition with altered Imax and Km in the presence of a range of betamethasone dipropionate concentrations.

Drug therapy for secondary lymphedema has not yet been established. Conventional oral and intravenous administration is difficult to administer in sufficient doses due to adverse events. Therefore, it is necessary to develop a transdermal delivery system that can deliver high concentrations of drugs to the edema area.

Phospholipase A (PLA) in goat semen aggregates with egg yolk in semen diluent, leading to sperm death. The aim of this study is to address the issue of sperm death caused by the interaction between PLA and egg yolk, and to explore the protective effect and metabolic regulation mechanism of the combination of dexamethasone (DXMS) and azithromycin (AZM) on goat sperm under low temperature conditions. At a low temperature of 4 °C, different concentrations of DXMS were added to semen diluents containing 30 μg/mL AZM to detect the quality of goat sperm.
