    Purpose The phenolic composition, antioxidant, antimicrobial activity, enzyme inhibition activity, and cytotoxic activity potentials of the plant Rumex acetosella L. (R. acetosella) were examined in this study. Materials and Methods: The chemical composition of R. acetosella methanol extract was identified by the LC-MS/MS method. The antioxidant activity was tested using beta-carotene/linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC reducing power, and metal chelating activity methods. The cytotoxic activity was determined by the MTT assay using human ovarian adenocarcinoma (Skov-3), glioblastoma (U87), human dermal fibroblasts (HDF), and human colorectal adenocarcinoma (CaCo-2) cell lines. The antimicrobial activity of methanolic extracts was tested on gram-negative (Escherichia coli and Pseudomonas aeuriginosa) and gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) using the in vitro minimum inhibition concentration method (MIC). Enzyme inhibition activity of R. acetosella methanol extract was measured spectrophotometrically against acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes. Results: The findings showed that the major components of the methanol extract content were luteolin-7-O-glucoside (1.599 m/L), polydatin (91,024 m/L), and shikimic acid (0.773 m/L). It was determined that the extract and standard antioxidant (a-tocopherol) results in DPPH center dot, and ABTS center dot + tests performed to determine the antioxidant activity were close to each other, and this value was more effective than the standard antioxidant (alpha-tocopherol) in the CUPRAC test. These results suggested that the plant's antioxidant potential was higher when compared with reference antioxidant compounds. It was determined that the methanol extract of R. acetosella had a weaker effect on the growth of the tested microorganisms than the antibiotics used as standard. The activity of the GST and AChE enzymes was found to be severely inhibited by the methanol extract of R. acetosella. Conclusion: Based on these findings, R. acetosella L. is a medicinal and commercially beneficial plant that warrants further investigation.

    Exploring Attendance at Emergency Departments for Children With Non-Urgent Conditions in Turkey: a Qualitative Study of Parents and Healthcare Staff Perspectives
    (Lippincott Williams & Wilkins, 2022) Bütün, Ahmet; Butun, Ahmet; Lynn, Fiona; McGaughey, Jennifer; McLaughlin, Katrina; Linden, Mark; 09.01. Department of Nursing / Hemşirelik Bölümü; 9.

    Background:Overcrowding in Emergency Departments (EDs) is a significant global concern with negative consequences for patients, healthcare staff, and healthcare systems. The use of EDs by parents of children with non-urgent conditions is associated with overcrowding, higher healthcare costs, lower quality of care, and longer waiting times. Research in this area has largely been conducted in high-income countries, with a dearth of work originating in middle and low-income regions. The aim of this study was to explore the reasons for parents attending EDs with their child for non-urgent conditions in Turkey.Method:Semi-structured interviews were conducted with 13 parents, 15 ED staff, and 10 General Practitioners (GPs) in 2 regions of Turkey between March and May 2017. Data were analyzed using the principles of grounded theory.Results:The findings were classified into 5 core categories: (1) parents' feelings, knowledge, and perceived inability to provide self-care; (2) perceived limitations of healthcare services, system, and staff; (3) parents' preferences for hospital and ED services; (4) adverse impact on ED services; and (5) perceived needs for care.Conclusion:This is the first study conducted in a middle-income country regarding parental reasons for using the ED for nonurgent conditions. Greater efforts must be made to reduce unnecessary visits to the ED to better meet service user needs and to increase the satisfaction of both parents and healthcare staff. The findings of this study may inform healthcare providers, policymakers, healthcare staff, and researchers to design interventions in order to mitigate overcrowding in the ED.
