Factors Affecting Breastfeeding in Births Given During the Day and at Night; A Cross-Sectional Comparative Study

Objective: How giving birth at night and during the day affects the breastfeeding process should be evaluated when health services are planned. In this study, we investigated the effect of giving birth at night and during the day on the breastfeeding process. Materials and Methods: In this cross-sectional comparative study, we included 228 women who gave birth at night and 192 women who gave birth during the day. We compared the effect of giving birth at night or during the day on breastfeeding with the univariate analysis in terms of intrapartum and postpartum factors. Results: While the mothers who gave birth during the daytime started the first breastfeeding earlier (p < 0.001), the duration of the first breastfeeding and skin-to-skin contact practice was longer in mothers who gave birth at night (p < 0.05). While the rate of formula supplementing in babies born at night was 44.8%, it was 55.2% in babies born during the day (p < 0.001). The rate of receiving support from health workers (p = 0.040) and intending to breastfeed babies exclusively after discharge (p < 0.05) was higher in mothers who gave birth during the day than it was in mothers who gave birth at night. Conclusion: Day and night labor have different advantages and disadvantages on breastfeeding. It is important to address these differences in terms of intrapartum and postpartum care process to prevent negative breastfeeding experiences in the early period.

Green Synthesis (Paeonia kesrouanensis) of Silver Nanoparticles and Toxicity Studies in Artemia salina

This study aims to describe a simple and environmentally friendly procedure for producing silver nanoparticles (AgNPs) using Paeonia kesrouanensis (P. kesrouanensis) extracts and to determine the toxic effect in the aquatic environment. The morphologies, size, size distributions, and structural properties were analyzed using SEM-EDX, TEM, DLS, zeta potential, FTIR, and XRD. AgNPs were applied to Artemia salina (A.salina), aquatic organism individuals at 7 different concentrations (0.0, 0.2, 1, 5, 10, 25, 50 mg/L) for 24, 48, and 72 h. AgNPs accumulation and elimination, ion release amounts, and the survival rates of organisms were determined at periods of 24, 48, and 72nd hours. The highest accumulation was observed at the 24th hour at the 50 mg/L exposure level. The survival rate decreased as exposure time increased at all concentrations.
