Background: Cognitive evaluation was considered to be very important in the relapse period, on the basis of the presence of isolated cognitive attacks and the necessity of monitoring the patient both physically and cognitively.

Materials And Methods: People with MS (pwMS) who were hospitalized during relapse were included in the study. All MS patients were evaluated by the neurologist with Expanded Disability Status Scale (EDSS), The 9 Hole Peg Test (9HPT) and the Timed 25-Foot Walk Test (T25-FWT).

Objectives: Multiple sclerosis (MS), which is known as a young-adult age disease, is called late-onset MS (LOMS) when it occurs at the age of 50 and older. In our study, we aimed to analyse the clinical and demographic characteristics, comorbidities, diagnostic and treatment challenges and prognosis of LOMS.

Methods: In a retrospective analysis of 136 patients diagnosed with multiple sclerosis (MS) after the age of 50, based on the 2017 McDonald criteria, and who were under observation in eight distinct MS centers across Turkey; demographic information, clinical characteristics of the disease, oligoclonal band (OCB) status, initial and current Expanded Disability Status Scale (EDSS) values, administered treatments, and the existence of spinal lesions on magnetic resonance imaging (MRI) were investigated.

Article Synopsis
  • This study focuses on the effectiveness of COVID-19 vaccinations in people with multiple sclerosis (pwMS) taking various disease-modifying therapies (DMTs), primarily comparing mRNA vaccines (like Pfizer-BioNTech) with inactivated virus vaccines (like Sinovac).
  • Results showed that while both types of vaccines resulted in similar rates of seropositivity, the mRNA vaccine group had significantly higher antibody levels compared to the inactivated virus vaccine group.
  • The study also found that pwMS on certain DMTs, specifically ocrelizumab, fingolimod, and cladribine, had reduced humoral responses to the vaccines, highlighting the impact of therapies on vaccine efficacy

Background: During multiple sclerosis (MS) treatment different modes of action such as lateral (interferon beta to glatiramer acetate or glatiramer acetate to interferon beta) or vertical (interferon beta/glatiramer acetate to fingolimod) drug switch can be performed. This study aims to investigate the clinical effectiveness of switching from the first-line injectable disease modifying treatments (iDMTs) to fingolimod (FNG) compared to switching between first-line iDMTs.

Methods: This is a multicenter, observational and retrospective study of patients with relapsing-remitting MS who had lateral and vertical switch.

Structural defects in transition metal dichalcogenide (TMDC) monolayers (ML) play a significant role in determining their (opto)electronic properties, triggering numerous efforts to control defect densities during material growth or by post-growth treatments. Various types of TMDC have been successfully deposited by MOCVD (metal-organic chemical vapor deposition), which is a wafer-scale deposition technique with excellent uniformity and controllability. However, so far there are no findings on the extent to which the incorporation of defects can be controlled by growth parameters during MOCVD processes of TMDC.

Introduction: Various restrictions due to the coronavirus infection have affected working life globally. People with multiple sclerosis (pwMS) have several difficulties in social life, patient follow-up, and receiving treatments. In this study, we aimed to evaluate the experiences of pwMS during the COVID-19 pandemic.

A promising strategy toward ultrathin, sensitive photodetectors is the combination of a photoactive semiconducting transition-metal dichalcogenide (TMDC) monolayer like MoS with highly conductive graphene. Such devices often exhibit a complex and contradictory photoresponse as incident light can trigger both photoconductivity and photoinduced desorption of molecules from the surface. Here, we use metal-organic chemical vapor deposition (MOCVD) to directly grow MoS on top of graphene that is deposited on a sapphire wafer via chemical vapor deposition (CVD) for realizing graphene-MoS photodetectors.

Background: Difficulties of self-management in people with MS (pwMS) is considered as one of the most important factors contributing to low rehabilitation efficacy, more severe long-term complications and increase in healthcare costs. Despite the emergence of research in the last decade documenting causes, types, and course of cognitive difficulties in MS disease subtypes, limited evidence is available in the literature for direct comparison of self-management and cognitive deficits. In this study we aimed to investigate the relationship between cognitive performance and self-management in pwMS.

Background: COVID-19 is a multisystemic infection with variables consequences depending on individual and comorbid conditions. The course and outcomes of COVID-19 during neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disorders (MOGAD) are not clearly known.

Objective/methods: The aim of this study was to examine the features and outcomes of COVID-19 infection in NMOSD and MOGAD patients.

Article Synopsis
  • The study explored why some multiple sclerosis (MS) patients experience worsening vision despite treatment, focusing on those with optic neuritis over nearly two decades.* -
  • Out of 1014 MS patients, 411 had optic neuritis; 11 displayed unusual symptoms prompting genetic testing for Leber's hereditary optic neuropathy, revealing mutations in 5 patients.* -
  • The prevalence of these mitochondrial mutations was 0.12%, suggesting they are linked to poor visual outcomes, and highlighting the need for genetic testing in MS patients with severe visual loss.*

Introduction: The primary aim of the present study was to evaluate the long-term efficacy of fingolimod in patients with multiple sclerosis (MS); secondary aims were to describe the safety of fingolimod with the evaluation of treatment satisfaction and impact on the quality of life in real life.

Methods: We collected clinical, demographical, neuroradiological, and treatment data, including pre- and posttreatment status health-related quality of life from 286 MS patients consecutively treated with fingolimod. Clinical assessment was based on the Expanded Disability Status Scale (EDSS), and quality of life assessment was performed with MS-related quality of life inventory (MSQOLI).

Background: Flammer syndrome (FS) occurs from well-described signs and symptoms. The syndrome itself is not a disease, but it may be a directive marker for advancing therapeutic approaches by predictive and preventive measures as well as for personalization of treatments. The syndrome is related to many diseases, but FS has been rarely studied in multiple sclerosis (MS).

Article Synopsis
  • The study found that 68% of multiple sclerosis (MS) patients reported experiencing headaches, with migraines being the most common type.
  • Among the patients, headaches frequently began after starting MS therapies, particularly interferon beta, which was associated with a higher incidence of headaches.
  • The findings suggest a potential link between the use of certain MS treatments and the onset of headaches, particularly migraines, with younger patients experiencing them earlier and more intensely.

Thermal chemical vapor deposition (TCVD) is the current method of choice to fabricate high quality, large area graphene films on catalytic copper substrates. In order to obtain sufficiently high growth rates at reduced growth temperatures an efficient dissociation of the precursor molecules already in the gas phase is required. We used plasma enhanced chemical vapor deposition (PECVD) to fabricate high quality graphene films at various temperatures.

Background Medication-overuse headache is a common clinical entity, but neuroimaging studies investigating volumetric and microstructural alterations of the brain in medication-overuse headache are rare. Therefore, in the current longitidunal study we evaluated gray matter volume and white matter integrity in patients with medication-overuse headache before and after drug withdrawal. Methods A prospective study evaluated 27 patients with medication-overuse headache and 27 age-, sex-, and education-matched healthy adults.
