    Analysis of Selected Steroid Hormones in Sea of Marmara Sediment Samples by Lc-esi/Ms-ms
    (Istanbul Univ, Fac Pharmacy, 2023) Aysel, Esra; Yurdun, Turkan
    Background and Aims: Sediment is the general name given to the muddy structure located at the bottom of aquatic environments such as the sea. In our study, the amounts of steroid hormones were investigated in the sediment samples taken from the Marmara Sea. According to other studies, it has been determined that the excess of the hormone load in the sediments may be an indicator of human/animal sourced pollution, as well as the negative effects of the hormones mixed in the seas with the ecological cycle on the health of humans and animals.Methods: In our study, 31 selected human/animal, plant, natural and synthetic hormone-steroids were studied using Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry (LC-ESI/MS-MS). Methanol and QuEChERS were used as extraction methods. Sediment samples were taken from a total of 27 points selected for sampling at the Marmara Sea.Results: According to the results we found, the androgens: androsterone (24.50-1718.18 ng g-1), testosterone (86.30-1600.32 ng g-1); the estrogens: mestranol (33.73-228.32 ng g-1), equilin (53.44-1232.53 ng g-1); the progestagens; pregnenolone (37.50374.76 ng g-1), progesterone (39.96-405.60 ng g-1); levonorgestrel (325.25 and 937.93 ng g-1); the fecal sterols: cholestanone (57.57-1726.32 ng g-1), coprostanol + epicoprostanol (51.43-1370.33 ng g-1); and the plant sterol; campesterol (35.30-1859.90 ng g-1) were the compounds detected.Conclusion: Estrogens and progestogens are active components of birth control pills, and cholestanone and coprostanol + epicoprostanol are steroids that are indicative of human/animal pollution. Coprostanol + epicoprostanol and cholestanone, which are indicators of fecal pollution, were detected in all sediment samples. In our study, steroid hormones were detected for the first time in Sea of Marmara sediments and possible environmental risks were evaluated.

    Molecular Epidemiology of Carbapenem-Resistant Acinetobacter Baumannii Isolates in Turkiye: Systematic Review
    (Kare Publ, 2023) Kilbas, Elmas Pinar Kahraman; Kilbas, Imdat; Ciftci, Ihsan Hakki; Kahraman Kilbas, Elmas Pinar
    The World Health Organization has designated carbapenem-resistant Acinetobacter baumannii (CRAB) as a "critical" pathogen on the global priority list of antibiotic-resistant bacteria. This study aims to discuss the molecular epidemiology of CRAB isolates in Turkiye in the last 12 years and the prevalence of gene regions associated with resistance or pathogenesis using a systematic review method. Our study consists of a literature search, determination of eligibility and exclusion criteria, qualitative analysis of studies, data extraction, and statistical analysis. All studies were analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines. The incidence rates of blaOXA-23, blaOXA-23-like, blaOXA-24/40, blaOXA-24/40-like, blaOXA-51, blaOXA-51-like, blaOXA-58, and blaOXA-58-like genes in CRAB strains were 76.4%, 68.6%, 1.2%, 3.4%, 97.0%, 98.6%, 8.4%, and 17.1%, respectively. It was determined that the prevalence of the blaOXA-23 and blaOXA-58 gene regions showed a statistically significant change over the years. Due to the high prevalence of A. baumannii strains carrying the blaOXA-23 variant, it is necessary to follow its geographical distribution and transposon and plasmid movements. Based on available data, molecular surveillance of CRAB strains should be standardized. In addition, sterilization and disinfection processes applied within the scope of an effective struggle against CRAB strains that can remain live on surfaces for a long time should be reviewed frequently.

    Evaluation of Coping Mechanism of Mothers of Children With Chronic Diseases During Coronavirus Disease 2019 Pandemic
    (Aves, 2024) Erkut, Zeynep; Kose, Selmin; Savaser, Sevim; Kaya, Gizem; Ogut, Nehir Ulu
    AIM: The aim of this study was to determine the problems, perceived stress, and coping with the stress of mothers of children with chronic diseases during the pandemic. METHODS: The study was conducted with cross-sectional design. The data were gathered from the mothers of children with chronic diseases who were followed up at the endocrine outpatient clinic of a hospital in Istanbul between February 1, 2021, and May 31, 2021. The data were collected by conducting face-to-face interviews with mothers of 117 children through information form, Perceived Stress Scale (PSS), and the Coping with Stress Scale (CSS). RESULTS: It was determined that 35.9% of the mothers stated that they had problems during the pandemic since their children suffered from chronic diseases. The mean scores of the mothers were 26.88 +/- 6.69 points for the PSS and 87.35 +/- 11.04 points for the CSS and there was a negative and weak correlation between their scale scores (r = -.190; p < .05). CONCLUSION: It was found that families faced many different problems during the pandemic, such as the treatment and control of their children. In case of extraordinary situations such as pandemics, nurses should provide planned guidance and counseling services to children with chronic diseases and their families in order to manage the negative situations they experience.

    Global Health Emergencies During the Pandemic and Their Solutions
    (Tubitak Scientific & Technological Research Council Turkey, 2021) Sencan, Irfan; Bulut, Dilek; Agalar, Canan; Sencan, Ismail Hakki
    Abstract: In this review, we evaluated health care problems, which were not common before pandemic outbreak but have been common issues after its appereance and approaches to control pandemic considering its influences on people. We revised current health care developing approaches under the light of experience obtained throughout the pandemic so far. The aim is to be prepared in advance for possible upcoming pandemics. As in Covid 19 pandemics, such long lasting and widely affecting situations, durability is also very important together with flexibility and quickness. To provide durability, we need global policies taking the health to its center as well as health system policies.Key words: Covid-19, health system, emergency, crisis, vulnerability, durability

    Antibiotic Use and Influencing Factors Among Hospitalized Patients With Covid-19: a Multicenter Point-Prevalence Study From Turkey
    (Galenos Publ House, 2022) Sencan, Irfan; Cag, Yasemin; Karabay, Oguz; Kurtaran, Behice; Guclu, Ertugrul; Ogutlu, Aziz; Agalar, Canan; Ergen, Pınar; Kul, Gülnur; Uzar, Hanife; Yiğit, Özge; Tasbakan, Meltem
    Background: Broad-spectrum empirical antimicrobials arc frequently prescribed for patients with coronavirus disease 2019 (COVID-19) despite the lack of evidence for bacterial coinfection. Aims: We aimed to cross-sectionally determine the frequency of antibiotics use, type of antibiotics prescribed, and the factors influencing antibiotics use in hospitalized patients with COVID-19 confirmed by polymerase chain reaction. Study Design: The study was a national, multicenter, retrospective. and single-day point prevalence study. Methods: This was a national, multicenter, retrospective, and single-day point-prevalence study, conducted in the 24-h period between 00:00 and 24:00 on November 18, 2020, during the start of the second COVID-19 peak in Turkey. Results: A total of 1500 patients hospitalized with a diagnosis of COVID-19 were included in the study. The mean age +/- standard deviation of the patients was 65.0 +/- 15.5, and 56.2% (n = 843) of these patients were men. Of these hospitalized patients, 11.9% (n = 178) were undergoing invasive mechanical ventilation or ECMO. It was observed that 1118 (74.5%) patients were receiving antibiotics, of which 416 (372%) were prescribed a combination of antibiotics. In total, 71.2% of the patients had neither a clinical diagnosis nor microbiological evidence for prescribing antibiotics. In the multivariate logistic regression analysis, hospitalization in a state hospital (p < 0.001), requiring any supplemental oxygen (p = 0.005). presence of moderate/diffuse lung involvement (p < 0.001), C-reactive protein >10 ULT coefficient (p < 0.001), lymphocyte count < 800 (p = 0.007), and clinical diagnosis and/or confirmation by culture (p <0.001) were found to be independent factors associated with increased antibiotic use. Conclusion: The necessity of empirical antibiotics use in patients with COVID-19 should be reconsidered according to their clinical, imaging, and laboratory findings.

    Obesity Risk Factors in Turkish Preschool Children: a Cross-Sectional Study
    (Cukurova Univ, Fac Medicine, 2022) Ozkaya, Sebnem Ozgen; Ozkaya, Volkan; Garipagaoglu, Muazzez
    Purpose: The present study aims to identify the potential risk factors - pre and post-pregnancy, children's, parental, and environmental factors - concerning obesity in Turkish preschool children.Materials and Methods: The cross-sectional study was conducted with 538 children aged 3-5 and their mothers in 25 private and public kindergartens using a face-to-face survey. Demographic, anthropometric, nutrition, sleep, and physical activity information during pregnancy, infancy, and preschool periods were evaluated. Two-day food records and anthropometric measurements of the children were collected.Results: The prevalence of overweight and obesity in preschool children was found to be 27.0%. Among the 28 potential risk factors examined, pre-pregnancy obesity (odds ratios (OR):1.108, confidence interval (CI): 1.042-1.179), post-pregnancy obesity (OR:4.350, CI: 2.053-9.217), caffeine intake >200 mg/day during pregnancy (OR:1.588, CI:1.031-2.446), father with obesity (OR: 1.089, CI: 1.027-1.155), enrolling a private rather than a public kindergarten (OR: 2.093, CI:1.298-3.376), fast eating (OR:3.355, CI: 1.175-9.583 min), short lunch duration (OR:0.966, CI:0.934-0.998), daily sleep of <10 hours (OR:2.522, 1.439-4.421), and finally screen time of >2 hours/day (OR:1.560, CI:1.012-2.405) were found to be significantly correlated with obesity in preschool children.Conclusion: Parental obesity, caffeine intake during pregnancy, eating speed, daily sleep, and screen time were determined as obesity risk factors in Turkish preschool children. Identifying maternal and child risk factors in early childhood, regulating lifestyle and obesogenic environment can be protective against obesity.
