Evaluation of Clinical Effects of COVID-19 Infection and Vaccines on Myasthenia Gravis.

Introduction: In this study, we aimed to investigate the clinical effects of COVID-19 infection and vaccines on Myasthenia gravis (MG) during the pandemic.

Methods: A total of 141 MG patients between April 2020 and December 2021 were retrospectively analyzed. Data including demographic and clinical characteristics of patients, COVID-19 test results, and vaccine types (mRNA-BNT162b2 and/or inactivated-CoronaVac) were recorded.

Association of serum elabela levels with carotid artery stenosis in patients with non-cardioembolic ischemic stroke.

Elabela (ELA) is a peptide of the apelinergic system and is known to play a role in endothelial homeostasis and vascular pathobiology. In this study, the relationship between carotid artery stenosis, which is the main culprit, and ELA level in patients with non-cardioembolic ischemic stroke was investigated. Cross-sectional observation included two groups of 40 patients with critical carotid artery stenosis and 40 patients with age-sex matched noncritical carotid artery stenosis.

Factors Associated with Hemorrhagic Transformation in Infarctions Involving the Posterior Circulation System.

Backgrounds And Purpose: Hemorrhagic transformation (HT) following stroke of the posterior circulation is a rare occurrence, and its risk factors remain relatively unknown. This study aimed at examining the rate of HT and its risk factors in patients enduring acute ischemic stroke in the territories of the vertebral, basilar, and posterior-cerebral arteries.

Materials And Methods: A total of 217 consecutive patients the risk factors for ischemic stroke were recorded and comprehensive biochemical, cardiac assessments, and neuroimaging were performed.

Significance of Multiple Acute Ischemic Lesions on Initial Diffusion-weighted Imaging in Stroke Patients and Relation of Toast Classification.

Background: It is important to know whether or not the stroke risk factors and etiologies of patients with multiple acute infarcts are different to those of patients with a single acute infarct.

Aim: The frequency of multiple acute infarct was investigated in ischemic stroke patients and a comparison was made of the characteristics of stroke patients with and without multiple acute infarct.

Patients And Methods: We reviewed the clinical records of 988 ischemic stroke patients who were admitted within 1 week of the onset of stroke and diffusion-weighted imaging (DWI) was performed on first presentation.

Serum Levels of Melatonin and Sleep Evaluation Scales in the Diagnosis of Sleep Disorders in Patients with Idiopathic Parkinson's Disease.

Introduction: Sleep disturbances, such as difficulty in initiation of sleep, decrease in total sleep duration and efficacy, frequent awakenings, and increased daytime sleepiness are among the most common non-motor symptoms in patients with idiopathic Parkinson's disease (PD). However, patients usually do not consider these symptoms as important as their motor symptoms, and do not complain. We aimed to investigate PD patients for subtle sleep disturbances using sleep evaluation scales, and to evaluate the relationship between these tests and the serum levels of melatonin during night-sleep.
