Publication Metadata only Examination of antimicrobial effect of fluoxetine in experimental sepsis model: An in vivo study(2022-10-01T00:00:00Z) Cakir, Ahsen; Bozali, Kubra; Celikten, Mert; Guler, Eray Metin; Sahan, Ebru; DURDU, BÜLENT; SÜMBÜL, BİLGE; KOÇYİĞİT, ABDÜRRAHİM; ŞAHAN, EBRU; DURDU, BÜLENT; SÜMBÜL, BİLGE; KOÇYİĞİT, ABDÜRRAHİMSince most infectious diseases can develop into sepsis, it is still a major medical problem. Some in-vivo studies showed promising properties of fluoxetine in the treatment of infections. This study aims the antimicrobial effect of fluoxetine on the inflammatory process used in the treatment of sepsis-modeled rats. Besides, to investigate the efficacy of fluoxetine on modifying the antibiotic effect of imipenem in the inflammatory response. An experimental sepsis model was divided into negative control, positive control, fluoxetine 5 mg/kg, imipenem 60 mg/kg, and combined (fluoxetine; imipenem). Procalcitonin (PCT), high-sensitivity C-reactive protein (hs-CRP), lactate, myeloperoxidase activity (MPO), the inflammation markers interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor-alfa (TNF-alpha), and monocyte chemoattractant protein-1 (MCP-1) levels were measured by enzyme-linked immunosorbent assay method. Oxidative stress markers, total oxidant status (TOS), total antioxidant status (TAS), total thiol (TT), and native thiol (NT) were measured using photometric methods. Oxidative stress index (OSI) was calculated according to TAS and TOS levels. The statistical analysis was performed by Statistical Package for Social Sciences version 22.0. After treatment with fluoxetine, imipenem, and combined groups, IL-1 beta, IL-6, TNF-alpha, MPO activity, MCP-1, hs-CRP, PCT, lactate, and the oxidative stress markers OSI, and disulfide levels were decreased (p < 0.05). The TT, NT, and TAS levels significantly statistically increased (p < 0.05). This research demonstrates that fluoxetine has effects as anti-inflammatory and antioxidant, and the combined treatment with antibioticum imipenem indicates positive synergistic effects in the experimental sepsis model.Publication Metadata only Utility of Rapid Antibody Test for Screening COVID-19 Among Healthcare Professionals(2020-10-01T00:00:00Z) Okay, Gulay; Kacmaz, Asiye Bahar; Sumbul, BİLGE; Bolukcu, Sibel; Akkoyunlu, Yasemin; Meric Koc, Meliha; SÜMBÜL, BİLGE; OKAY, GÜLAY; DURDU, BÜLENT; AKKOYUNLU, YASEMİNObjective: This study aims to assess the effectivity of a rapid antibody test on detecting the occupational exposure in healthcare professionals who have been working in a pandemic hospital since the initial cases were seen in our country.Publication Metadata only Association between Consumption of Cow-s Milk and Iron Deficiency Anemia in Children: Are There Roles for Hepcidin-25/Ferroportin? A Case-Control Study(2020-07-01T00:00:00Z) Vehapoglu, Aysel; Ozgurhan, Gamze; USTABAŞ KAHRAMAN, Feyza; ÇAKIN, ZEYNEP EBRU; SÜMBÜL, BİLGE; VEHAPOĞLU TÜRKMEN, AYSEL; USTABAŞ KAHRAMAN, FEYZA; ÇAKIN, ZEYNEP EBRU; SÜMBÜL, BİLGESystemic iron homeostasis is regulated by the interaction of the peptide hormone, hepcidin and the iron exporter, ferroportin. The objective was to investigate the relationship between the consumption of cow-s milk and iron deficiency anemia in children 2-10 years old and its association with the hepcidin-25 and ferroportin concentrations. The study population consisted of 187 prepubescent children of similar ideal body weight (IBW:90-120%); 82 children with iron deficiency anemia (37girls and 45boys; 4.27 +/- 0.28 years) and 105 (47girls and 58boys; 4.25 +/- 0.34 years) healthy age-sex-matched controls. Serum fasting hepcidin-25/ferroportin concentrations were measured by enzyme immunoassay in all subjects. Mean cow-s milk consumption in the anemic group (373 +/- 248 mL/d) tended to be higher than that in the control group (320 +/- 226 mL/d), but the result was not statistically significant (p = 0.063).The mean hepcidin-25 level was significantly higher in the anemic group (19.5 +/- 18.4 ng/mL) than in the healthy controls (11.0 +/- 10.7, p < 0.001). The mean ferroportin level was lower in the anemic group (21.04 +/- 5.74 ng/mL) than in the healthy controls (22.68 +/- 4.77 ng/ml, p = 0.037). Consuming cow-s milk was not associated with IDA in prepubertal children, provided that it was adequately supplemented with iron-enriched foods. We observed a significant increase in hepcidin-25 levels and a decrease in ferroportin levels in children with iron deficiency anemia compared with healthy controls. Children who consumed more cow-s milk had higher levels of hepcidin-25. Iron deficiency anemia is not a concern when cow-s milk is given to children if the complementary foods are rich in iron.Publication Metadata only Efficacy of Tocilizumab in Patients with a Moderate and Severe COVID-19: A Retrospective Single Center Cohort Study(2021-11-01T00:00:00Z) Karakuş, Hatice Dilara; Okay, Gülay; Akkoyunlu, Yasemin; Sümbül, Bilge; Durdu, Bülent; Meriç Koç, Meliha; Aslan, Turan; KARAKUŞ, HATİCE DİLARA; OKAY, GÜLAY; AKKOYUNLU, YASEMİN; SÜMBÜL, BİLGE; DURDU, BÜLENT; MERİÇ KOÇ, MELİHA; ASLAN, TURANPublication Metadata only A Snapshot of Pediatric Patients with COVID-19 in a Pandemic Hospital(2020-10-01T00:00:00Z) BURSAL DURAMAZ, BURCU; TÜREL, Özden; KORKMAZ, ÇİĞDEM; KARADOĞAN, MUHAMMED TALHA; Yozgat, Can Yilmaz; İŞCAN, AKIN; SÜMBÜL, BİLGE; ERENBERK, UFUK; BURSAL DURAMAZ, BURCU; TÜREL, ÖZDEN; KORKMAZ, ÇİĞDEM; KARADOĞAN, MUHAMMED TALHA; İŞCAN, AKIN; SÜMBÜL, BİLGE; ERENBERK, UFUKAim Reports describing coronavirus disease 2019 (Covid-19) in children are fewer than adult studies due to milder clinical picture.

However, to our knowledge, there is no periprosthetic joint infection case reported that is infected with Streptococcus dysgalactiae subspecies equisimilis (SDSE) in the English literature. In this article, we report a 77 -year -old male patient who had undergone total knee arthroplasty three years ago and had the diagnosis of cellulitis at his leg followed by swelling, pain and hyperemia localized at his knee. Three knee aspirations were performed and the SDSE was identified. There was no direct contact of patient to animals.Publication Metadata only Investigation of the changing etiology and risk factors of prosthetic joint infections : a university hospital surveillance study from 2011-2017(2020-03-01T00:00:00Z) Gultepe, Bilge Sumbul; OKAY, GÜLAY; Bolukcu, Sibel; DURDU, BÜLENT; Koc, Meliha Meric; TUNCAY, İBRAHİM; BOLUKÇU, SİBEL; DURDU, BÜLENT; SÜMBÜL, BİLGE; TUNCAY, İBRAHİM; MERİÇ KOÇ, MELİHAWe sought to characterize the causative pathogens of prosthetic joint infections (PJIs), evaluate the trends in microbial etiologies, and identify potential risk factors for PJI. This was a retrospective study analyzing 70 patients with PJI following 3,253 total joint arthroplasties between 2011 and 2017. Staphylococci were the most common cause of infection (52.9%). There was a significant trend in the percentage of carbapenem-resistant gram-negative bacilli (GNB) (increased to 66.7% in 2016 from 0.0% in 2011) (p=0.021). GNB and polymicrobial etiology were found at significantly high levels in cases involving early PJIs (p=0.005 and p=0.048, respectively). While staphylococci were significantly higher in PJIs after total knee arthroplasty (75%), GNB were significantly higher in PJIs after total hip arthroplasty (49.1%) (p<0.001 and p=0.001, respectively). Binary logistic regression analysis showed that the risk of PJI was significantly higher in cases with fracture and diabetes mellitus (odds ratio [OR], 4.3, 95% confidence interval [CI], 1.78-10.5; OR, 4.1, 95% CI, 1.66-10.5, respectively). These results suggest that the empirical and targeted antimicrobial treatment of PJIs may become more difficult in the future.
