Article Citation - WoS: 2Differences in the Differential Expression of Micrornas Between Patients With Familial Multiple Sclerosis and Those With Sporadic Multiple Sclerosis(Galenos Publ House, 2023-12-28) Güllüoğlu, Halil; Uysal, Hasan Armağan; Poyraz, Turan; Altun, Zekiye; Kaya, Derya; Özcelik, Pınar; İdiman, Egemen; Poyraz, TuranObjective: Multiple sclerosis (MS) is a heterogeneous disease with clinical and immunological features. Most MS cases occur sporadically, but a considerable proportion of patients have a family history of MS. The etiology and pathophysiology of MS remain unclear. Recent epidemiological and gene expression studies have indicated that dysregulation of microRNAs (miRNAs) may play a role in MS pathogenesis. This study aimed to evaluate the differential expression of miRNAs in sporadic MS (sMS) and familial MS Materials and Methods: This cross-section, single-center study was conducted in 20 FMS and 10 sMS patients and 8 healthy controls. The patients were in the remission. In total, 2,549 miRNA genes were screened in the blood mononuclear cells from the whole blood samples of MS patients depending on miRBase 21. Differential expression of miRNAs in MS patients was identified compared with the control group, and miRNAs with a fold change >= 2 were validated using reverse transcription-polymerase chain reaction. Differentially expressed miRNAs were then compared between FMS and sMS patients. Results: Initial findings showed that miR-5100 and hsa-miR-16-2-3p were increased and miR-432-3p was decreased in FMS compared with sMS, whereas miR-548-aa, hsa-miR-142-3p, and miR-451-b were increased in both sMS and FMS, but miR-548-v was increased only in sMS. Some miRNAs showed the same expression patterns in both groups. Conclusion: Differential expression of certain miRNAs may be a useful biomarker in the diagnosis of MS. This study showed that miRNAs may discriminate between FMS and sMS cases and MS subtypes, as indicated in earlier studies.Article Cortical Thickness Alterations in Parkinson's Disease With Mild Cognitive Impairment(Galenos Publ House, 2023-07-03) Çavuşoğlu, Berrin; Hünerli, Duygu; Kıyı, İlayda; Çakmur, Raif; Yener, Görsev; Ada, EmelObjective: This study investigated cortical thickness differences and their relationships with cognitive functions in Parkinson's disease (PD) with mild cognitive impairment (MCI) and cognitively normal (CN). Materials and Methods: Twenty-two patients with PD-MCI, 23 with PD-CN, and 23 healthy controls with structural brain magnetic resonance imaging scans and complete neuropsychological tests were enrolled in this study. Cortical thickness analysis was performed using the Statistical Parametric Mapping 12 software package. Correlations with cognitive functions were examined. Results: Cortical thickness was significantly lower in the PD-CN and PD-MCI patient groups than in healthy controls in the left precuneus and isthmus-cingulate cortex, right pars orbitalis, insula, and lateral orbitofrontal cortex. In addition, the PD-MCI group also exhibited cortical thinning in the left superior temporal gyrus, transverse temporal cortex, supramarginal gyrus, and bilateral posterior cingulate cortex compared with healthy controls. Correlation analyses among cortical thickness and cognitive scores of PD also revealed moderate associations between memory and the posterior cingulate cortex; language and the precuneus; and executive functions and the insula and isthmus-posterior cingulate cortices. Conclusion: MCI in PD may be related to cortical alterations in the posterior cingulate cortex and the left temporoparietal cortex, which has been associated with subtle cognitive deficits in PD.Article Citation - WoS: 1Citation - Scopus: 1Comparison of Facial Palsy Cases Before and During the Pandemic Coronavirus Disease-2019(Galenos Publ House, 2023-06-23) Uysal, Hasan Armağan; Güllüoğlu, HalilObjective: The pandemic coronavirus disease-2019 (COVID-19) is caused by a novel type of coronavirus named severe acute respiratory syndrome coronavirus-2 and is rapidly spreading all over the world. In addition to various neurological symptoms, acute facial palsy was diagnosed as the main neurological symptom in some COVID-19 patients. The current study aimed to analyze the variation and any possible association in the case numbers or medical symptoms of patients with facial palsy before and during the COVID-19 pandemic.Methods: The clinical files of patients who were diagnosed with facial palsy in the Neurology Department of Medicalpoint Hospital, University of Economics Faculty of Medicine, Izmir were retrospectively investigated. To compare the facial palsy cases according to different periods, two patient groups were formed: before the COVID-19 pandemic and during the COVID-19 pandemic. The pandemic group was further divided into two subgroups as COVID-19-positive and COVID-19-negative patients to compare the effects of COVID-19 on facial palsy.Results: During the specified COVID-19 period (May 2020-January 2021) of the study, 38 patients were admitted to the hospital for facial palsy; 34 facial palsy patients were admitted in the same calendar period as the two previous years (May 2018-January 2019). There was no significant difference in the frequency of facial palsy between these two time periods. There were significant differences between before and during the COVID-19 pandemic groups regarding response to cortisone therapy (p<0.001), facial palsy grade (p<0.001), electromyography findings (p=0.005), denervation (p<0.001), and 6 months recovery (p<0.001) data. There were also significant differences between the COVID-19-positive and COVID-19-negative subgroups regarding response to cortisone therapy (p=0.015) and facial palsy grade (p=0.001).Conclusion: The current study findings support the possible association between the severity of the clinical course of facial palsy and COVID-19. Further studies are needed to prove a direct association between facial palsy and COVID-19.Article The Experience of Women Infected by the Covid-19 During Pregnancy: a Qualitative Study(Galenos Publ House, 2023-03-23) Ugurlu, Meltem; Kıratlı, Didem; Yavan, TülayObjective: To gain deeper understanding of experiences of pregnant women infected with coronavirus disease-2019 (COVID-19) during the Methods: This study, which was planned as a descriptive qualitative study, was performed out with 15 pregnant women infected with COVID-19. The data were collected between January 5th and March 15th, 2021 using a semi-structured interview form and in-depth interview method. Content analysis, one of the qualitative research method, was used to evaluate the data. The research was planned based on the Qualitative Research Reporting Consolidated Criteria checklist, which is a guide for qualitative research. Results: Four main themes were found in experiences of pregnant women infected with COVID-19: (1) psychosocial health; (2) change in daily routines on quarantine days, (3) coping and (4) perinatal period changes. Pregnant women experienced both psychological and physical difficulties. They used the expression closed box to describe the anxiety and anxious state experienced due to the uncertainty of the perinatal outcomes brought about by COVID-19 during pregnancy. Conclusion: Understanding the experiences of pregnant women infected with COVID-19 is the first step in determining treatment and care management for nurses and healthcare professionals. During the pandemic period, pregnant women need to reach prenatal care services on time, to support them physically and psychosocially, to provide information with e-health services, and to provide remote follow-up support to cope with the process.
