We aimed to assess the diagnostic performance of 85B mRNA-based RT-qPCR by comparing with the real-time PCR COBAS TagMan MTB Kit while using the BACTEC MGIT 960 method as the gold standard.Publication Metadata only 2015-2018 Dönemi HIV Tarama ve Doğrulama Verilerinin Seroepidemiyolojik Değerlendirilmesi(2019-03-13T00:00:00Z) DİNÇ, HARİKA ÖYKÜ; Özbey, Doğukan; YÜKSEL MAYDA, PELİN; KUŞKUCU, MERT AHMET; MİDİLLİ, KENAN; KOCAZEYBEK, BEKİR SAMİ; DİNÇ, HARİKA ÖYKÜ; YÜKSEL MAYDA, PELİNPublication Metadata only İÜC.

The aim of this study was to investigate the prevalence of Ad-36 antibodies in obese children, as well as investigate the role of serum leptin and lipid levels in Ad-36-obesity. Seventy-one obese children and 62 non-obese children were included as the patient group (PG), including the healthy control group (HCG), respectively. Simultaneously, Ad-36 antibodies and adipokine levels were assessed with serum neutralization assays (SNA) and ELISA. Ad-36 antibody was detected in 9 patients (12.7%) and 1 patient (1.6%) in both the PG and HCG, respectively, while a significant difference was detected between groups (p < 0.05). Although serum LDL, total cholesterol, triglycerides and leptin levels were detected significantly higher, adiponectin level was detected paradoxically lower in the PG. However, a significant difference was not detected for lipids and leptin levels; adiponectin levels were found to be significantly lower in Ad-36 antibody-positive PG (p < 0.05).Publication Metadata only Travel-associated infections caused by unusual serogroups of Legionella pneumophila identified using Legionella BIOCHIP slides in Turkey and Iraq(2016-05-01T00:00:00Z) Kocazeybek, Bekir S.; Yuksel, Pelin; Keskin, Dilek; Sheikh, Suhail; Habip, Zafer; Yavuzer, Serap Sahin; Caliskan, Reyhan; Altun, Yagiz Meric; Kuskucu, Mert; Cengiz, Mahir; Dinc, HARİKA ÖYKÜ; Karakullukcu, Asiye; Ergin, Sevgi; Saribas, Suat; Yilmaz, Nail; Tokman, Hrisi Bahar; YÜKSEL MAYDA, PELİN; DİNÇ, HARİKA ÖYKÜBackground: Although Legionella pneumophila serogroup 1 is the common disease causing serogroup, rare serogroups can also may cause legionellosis. A 54-year-old male patient (index case) reported that he had been on a religious trip (for visiting, tomb of Ali, which is important for Shias) to Iraq with a large group (50 shia pilgrims from Kars city of Turkey) two weeks prior to admission. Due to civil war, the hotel where the patient stayed in Iraq lacked proper hygiene. A large number of people in the travel group were experiencing the same symptoms. Other five cases were 2 males (ages; 50, 45) and 3 females including the wife of the index case (ages; 50, 28, 27).Publication Metadata only Cytomegalovirus (CMV) Seropozitif Olguların Demografik Verileri İle Birlikte Retrospektif Olarak Değerlendirilmesi(2016-02-25T00:00:00Z) BAKIR, ESRA; DİNÇ, HARİKA ÖYKÜ; aydoğan, okan; YÜKSEL MAYDA, PELİN; KOCAZEYBEK, BEKİR SAMİ; DİNÇ, HARİKA ÖYKÜ; YÜKSEL MAYDA, PELİNPublication Metadata only Serum neopterin and procalcitonin levels in relationship with pediatric burn wound infections(2016-03-01T00:00:00Z) Pilanci, Ozgur; Ergin, Sevgi; Sirekbasan, Serhat; Ersin, Idris; Habip, Zafer; Yuksel, Pelin; Kuvat, Nuray; Aslan, Mustafa; Dinc, Oyku; Saribas, Suat; Kocazeybek, Bekir; YÜKSEL MAYDA, PELİN; DİNÇ, HARİKA ÖYKÜInfection and septic complications in burn patients can be monitored by procalcitonin (PCT) and neopterin plasma values. The aim of the study was to investigate serum neopterin and PCT levels with WBC (white blood cell) and CRP (C-reactive protein) levels in patient group (PG) and healthy control group (HCG) and to investigate the relationship of these markers with burn wound infections (BWI). As the PG, 23 patients between 0-12 ages and up to 30% Total Body Surface Area (TBSA) burned and 15 HCG were included. PCT, neopterin, WBC, and CRP results on the first, the seventh, the fourteenth and the 21st day have been compared. During the follow-up period, 11 patients with BWI and 12 patients without BWI were classified as infected and non-infected patients, respectively. PCT and neopterin levels were detected higher in patients with BWI but no significant difference were present. Also, PCT and neopterin levels within the first 24 hours following the burn were detected higher in PG than HCG. CRP and WBC levels were detected high due to burn trauma. PCT and neopterin levels were increased in patients with BWI. PCT levels were increased during the pre-infectious period, while neopterin levels increased during the post-infectious period.Publication Metadata only İÜC.
