    Cerebrovascular radiological features of COVID-19 positive patients
    (Verduci Publisher, 2022) Petik, B.; Akcicek, M.; Sahin, M.; Dag, N.
    OBJECTIVE: To investigate acute cerebrovascular diseases (stroke and intracranial hemorrhage) by cranial radiologic examinations of patients infected with coronavirus disease 2019 (COVID-19) and with neurological signs. PATIENTS AND METHODS: Between March 2020 and May 2021, patients who were admitted to the Emergency Department and had a positive reverse transcription-polymerase chain reaction (RT-PCR) test and underwent Multidetector Computed Tomography (MDCT) and/or Magnetic Resonance Images (MRI), and/or diffusion MRI due to neurological findings were included in the study. RESULTS: The study reviewed a total of 925 patients, including 404 (43.67%) female and 521 (56.32%) male patients. The distribution of imaging methods was as follows: 805 (71%) patients had cranial MDCT, 71 (6.35%) patients had MRI, and 241 (21.57%) patients had diffusion MRI. Of the total 925 patients, 128 (13.8%) patients were detected with cerebrovascular diseases, 92 (9.9%) patients were detected with ischemic or hemorrhagic stroke, 37 (4%) patients were detected with intraparenchymal hemorrhage, 10 (1.1%) patients were detected with subarachnoid hemorrhage, and four (0.43%) patients were detected with subdural hemorrhage. There was no statistically significant difference in the incidence of subdural, subarachnoid, parenchymal hemorrhage. and stroke in terms of gender. While there was a significant difference in stroke according to age, there was no statistically significant difference in subdural, subarachnoid, and parenchymal hemorrhagic. Three (0.32%) patients were diagnosed with acute disseminated encephalomyelitis (ADEM)'s-like demyelinating lesions. CONCLUSIONS: Cerebrovascular diseases, which may cause severe disability and even threaten the patient's life, should be kept in mind, especially in COVID-19 patients who present with neurological symptoms.

    Clinical significance of ADAMTS1, ADAMTS5, ADAMTS9 aggrecanases and IL-17A, IL-23, IL-33 cytokines in polycystic ovary syndrome
    (Springer, 2016) Karakose, M.; Demircan, K.; Tutal, E.; Demirci, T.; Arslan, M. S.; Sahin, M.; Celik, H. T.
    Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age. A disintegrin and metalloproteinase with thrombospondin-like motifs (ADAMTS) are involved in inflammation and fertility. The aim of this investigation was to evaluate the serum levels of ADAMTS1, ADAMTS5, ADAMTS9, IL-17, IL-23, IL-33 and to find out the relationship between these inflammatory cytokines and ADAMTSs in PCOS patients. A case-control study was performed in a training and research hospital. Eighty patients with PCOS and seventy-eight healthy female volunteers were recruited in the present study. Serum ADAMTS and IL levels were determined by a human enzyme-linked immunoassay (ELISA) in all subjects. The IL-17A, IL-23 and IL-33 levels were significantly higher in the PCOS patients compared to the controls (p < 0.05). We could not find significant difference between the groups in terms of ADAMTS1, ADAMTS5 and ADAMTS9 levels. IL-17A had positive correlations with LDL cholesterol and IL-33 and negative correlations with ADAMTS1, ADAMTS5, and ADAMTS9. IL-33 had positive correlation with LDL cholesterol and IL-17A. In ROC curve analysis, PCOS can be predicted by the use of IL-17A, IL-23 and IL-33 which at a cut-off value of 8.37 pg/mL (44 % sensitivity, 83 % specificity), 26.75 pg/mL (36 % sensitivity, 64 % specificity) and 14.28 pg/mL (83 % sensitivity, 39 % specificity), respectively. The results of the study might suggest that ADAMTS and IL molecules have a role in the pathogenesis of the PCOS. Further efforts are needed to establish causality for ADAMTS-IL axis.

    Usefulness of the neutrophil-to-lymphocyte ratio to prediction of type 2 diabetes mellitus in morbid obesity
    (Elsevier Sci Ltd, 2015) Yilmaz, H.; Ucan, B.; Sayki, M.; Unsal, I.; Sahin, M.; Ozbek, M.; Delibasi, T.
    Background: There is growing consensus in the literature that inflammation plays a central role in the pathophysiology of obesity and type 2 diabetes mellitus (T2DM) and cardiovascular complications. Neutrophil-to-lymphocyte ratio (NLR) provides a simple method for assessment of inflammatory status and it is a new, inexpensive marker. The aim of the present study was to investigate the predictive value of preprocedural (before the OGTT) NLR on development of type 2 diabetes (T2DM) in morbid obesity patients (MOP). Methods: 306 MOP (body mass index >= 40 kg/m(2)) and 95 normal weight patients with normal OGTT [ fasting plasma glucose (FPG) < 100 mg/dL. Two-hour glucose during OGTT < 140 mg/dL] were evaluated in this study. Results: The mean +/- SD NLR of MOP was significantly higher than that of patients with normal weight healthy patients (3.67 +/- 0.95 vs. 1.82 +/- 1.02, P < 0.001, respectively). In receiver operating characteristics curve analysis, NLR > 3.12 had 79.2% sensitivity and 64.9% specificity in predicting T2DM. Logistic regression analysis showed that elevated NLR (OR: 2.577, 95% CI: 1.363-4.872, P = 0.004) was an independent variable for predicting T2DM in MOP. Conclusions: MOP have higher NLR than healthy controls. High NLR is a powerful and independent predictor of T2DM in MOP. Elevated NLR levels are usually considered as an inflammatory marker. The results of this study suggested that inflammation plays a role in the pathogenesis of T2DM with MOP. (C) 2014 Diabetes India. Published by Elsevier Ltd. All rights reserved.
