Assessing mental flexibility in the older population with low levels of education.

ΑBSTRACT The Trail Making Test (TMT) is widely used for the assessment of mental flexibility in older individuals, but those with limited education are often unable to perform Part B; thus, we explored its clinical utility in assessing an older cohort with low education. Moreover, we explored the clinical utility of speedy reciting of the months of the year (MY) backwards (MB) as an alternative.  We administered the TMT and MY to a sample of cognitively healthy individuals >64 years old and individuals with dementia who participated in a population-based epidemiological study, the Hellenic Longitudinal Investigation of Aging and Diet.

Investigating the link between Helicobacter pylori infection and psoriatic disease: an immunological study.

Helicobacter pylori (Hp) has been postulated as an infectious trigger of psoriatic disease, namely psoriasis (Ps) and psoriatic arthritis (PsA), but meticulous antibody (ab) reactivity against all dominant and subdominant Hp antigens in demographically matched PsA and Ps patients and healthy controls has not been performed so far. IgG anti-Hp ab testing was performed by combining immunoblotting and line assays in 263 serum samples from 89 patients with PsA, 114 patients with Ps, and 60 demographically matched healthy controls (HCs). Anti-Hp positivity did not differ between PsA, Ps, and HCs (P > 0.

Risk of multiple sclerosis in patients with psoriasis receiving anti-IL-17 agents: A case-based review.

Biologics approved for psoriasis exhibit favorable safety profiles, and serious adverse events have rarely been reported. In this report, we present the case of a patient treated with ixekizumab, an anti-interleukin (IL)-17 agent, who 8 months later developed multiple sclerosis (MS). We also review the available literature regarding the use of anti-IL-17 agents in the context of psoriasis and pre-existing or new-onset demyelination.

Real-World Assessment of Quality of Life in Patients with Relapsing Remitting Multiple Sclerosis Treated with Teriflunomide for Two Years: Patient-Reported Outcomes from the AURELIO Study in Greece.

Introduction: Multiple sclerosis (MS) is a highly heterogeneous inflammatory disease of the central nervous system. Patient-reported outcomes (PROs) in a real-world clinical setting can provide detailed information about MS from the patient's perspective. PROs were used here to assess quality of life (QoL), treatment satisfaction, clinical efficacy, and safety outcomes in a Greek cohort of relapsing remitting MS (RRMS) patients treated with oral teriflunomide (14 mg/day).

Natalizumab therapy in patients with pediatric-onset multiple sclerosis in Greece: clinical and immunological insights of time-long administration and future directions-a single-center retrospective observational study.

Pediatric-onset multiple sclerosis (MS, POMS) accounts for 3-5% of all MS cases and is characterized by a highly inflammatory profile, often warranting treatment with high-efficacy agents. Our aim is to present real-world data of a series of 18 Hellenic POMS patients treated with natalizumab (NTZ) either as adolescents or as adults, after high disease activity has efficiently subsided. Clinical and imaging/laboratory data from 18 POMS patients who have received at least one NTZ infusion were selected in this single-center retrospective observational study.

Prolonged Cardiac Monitoring and Stroke Recurrence: A Meta-analysis.

Background And Objectives: Prolonged poststroke cardiac rhythm monitoring (PCM) reveals a substantial proportion of patients with ischemic stroke (IS) with atrial fibrillation (AF) not detected by conventional rhythm monitoring strategies. We evaluated the association between PCM and the institution of stroke preventive strategies and stroke recurrence.

Methods: We searched MEDLINE and SCOPUS databases to identify studies reporting stroke recurrence rates in patients with history of recent IS or TIA receiving PCM compared with patients receiving conventional cardiac rhythm monitoring.

Tetracyclines Diminish IFN-γ and IL-17-Producing Adaptive and Innate Immune Cells in Multiple Sclerosis.

Introduction: Limited data from clinical trials in multiple sclerosis (MS) reported that minocycline, a widely used antibiotic belonging to the family of tetracyclines (TCs), exerts a beneficial short-lived clinical effect A similar anti-inflammatory effect of minocycline attributed to a deviation from Th1 to Th2 immune response has been reported in experimental models of MS. Whether such an immunomodulatory mechanism is operated in the human disease remains largely unknown.

Aim: To assess the immunomodulatory effect of tetracyclines, and in particular minocycline and doxycycline, in naïve and treated patients with MS.

Primary Sjögren's syndrome (pSS)-related cerebellar ataxia: a systematic review and meta-analysis.

Background: Primary Sjögren's syndrome (pSS) is a chronic autoimmune disorder characterized by lymphocytic infiltrates of the exocrine glands, particularly the salivary and lacrimal glands, resulting in oral and ocular dryness. pSS has been linked to various neurological manifestations, including cerebellar dysfunction. We aimed to provide a comprehensive analysis of the currently available evidence regarding pSS-related cerebellar ataxia.

Depression and Obesity in Patients With Psoriasis and Psoriatic Arthritis: Is IL-17-Mediated Immune Dysregulation the Connecting Link?

Patients with psoriasis are frequently obese and experience anxiety or suffer from depressive disorders. The immunopathogenesis of psoriasis and indeed psoriatic arthritis is largely based on the pivotal role of IL-17/IL-23 axis, to an extent that currently monoclonal antibodies selectively inhibiting IL-17 or IL-23 are routinely used for the treatment of psoriatic diseases. Emerging data, demonstrating a decisive role for IL-17 and IL-17 producing cell subsets, such as Th17 in the induction and progression of obesity and depression has led authors to suggest that psoriatic disease, obesity and anxiety/depression may indeed be interconnected manifestation of a state of immunedysregulation, the linked being IL-17 and its related cells.

A meta-analysis on potential modifiers of LITT efficacy for mesial temporal lobe epilepsy: Seizure-freedom seems to fade with time.

Background: The efficacy of laser interstitial thermal therapy (LITT) in mesial temporal lobe epilepsy (MTLE) has not been clearly established yet.

Objective: We conducted a meta-analysis to estimate the efficacy of LITT for TLE (Q1). We also examined the effect of the patient's age (Q2), the total ablation volume (TAV) (Q3), the strength of the MRI unit (Q4), the type of the utilized stereotactic platform (Q5), and the follow up period (Q6) on the patient's outcome.

Spasm of the near reflex: a common diagnostic dilemma?

Aim: To report the clinical characteristics and diagnostic procedures used in patients with spasm of the near reflex (SNR), in order to present common investigation strategies and diagnostic pitfalls.

Methods: Retrospective case series of twenty-two patients, mainly children, with SNR or accommodation spasm (AS). AS was diagnosed on the basis of blurred vision and a difference of ≥2 dioptres between manifest and cycloplegic retinoscopy.

The Role of the T2-FLAIR Mismatch Sign as an Imaging Marker of IDH Status in a Mixed Population of Low- and High-Grade Gliomas.

Our study evaluated the role of the T2-fluid-attenuated inversion recovery (FLAIR) mismatch sign in detecting isocitrate dehydrogenase (IDH) mutations based on a mixed sample of 24 patients with low- and high- grade gliomas. The association between the two was realized using univariate and multivariate logistic regression analysis. There was a substantial agreement between the two raters for the detection of the T2-FLAIR mismatch sign (Cohen's kappa coefficient was 0.

Helicobacter pylori infection as a potential risk factor for multiple sclerosis.

Helicobacter pylori infection (Hp-I) has been associated with a wide spectrum of gastrointestinal and extra-digestive manifestations, including neurodegenerative diseases. Contradictory data have been published on Hp-I and multiple sclerosis (MS) association, with studies mainly using serology for Hp-I detection that cannot distinguish between active and past infections. We herein hypothesize that humoral and cellular immune responses induced by active Hp-I, beyond damaging locally the gastric mucosa, they may shape the character of systemic autoimmune responses, contributing to MS pathogenesis.

A study of antigen-specific anti-cytomegalovirus antibody reactivity in patients with systemic sclerosis and concomitant anti-Ro52 antibodies.

Anti-Ro52 autoantibody (autoAb), highly prevalent in Sjogren's syndrome (SjS) and systemic lupus erythematosus (SLE), is also frequent in systemic sclerosis (SSc). Viral agents, such as human cytomegalovirus (HCMV), have been considered as a trigger for SSc and SSc-associated autoAbs. To seek for antigen-specific anti-HCMV associations with anti-Ro52, we assessed the dominant anti-HCMV ab responses in anti-Ro52 antibody (ab)-positive and -negative patients with SSc and compared them with those in SLE and SjS.

Symbol Digit Modalities Test: Greek Normative Data for the Oral and Written Version and Discriminative Validity in Patients with Multiple Sclerosis.

Objectives: The purpose of this study was to generate normative data on the Symbol Digits Modalities Test (SDMT) for the written and oral versions in the Greek adult population. We also investigated the test's validity in discriminating the performance of healthy adults from two groups of adults diagnosed with relapsing remitting (RRMS) and secondary progressive (SPMS) multiple sclerosis.

Method: The sample consisted of 609 healthy men and women between the ages of 18 and 65.

A comprehensive analysis of antigen-specific autoimmune liver disease related autoantibodies in patients with multiple sclerosis.

Introduction: Abnormal liver function tests are frequently seen in patients with multiple sclerosis (MS) and their origin at times is attributed to the possible co-occurrence or the de novo induction of autoimmune liver diseases (AILD), namely autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC), but comprehensive analysis of AILD-related autoantibody has not been carried out.

Aim: To assess the presence of AILD-related autoantibodies in a well-defined cohort of MS patients, and to assess their clinical significance.

Materials And Methods: 133 MS (93 female) patients (102 RRMS, 27 SPMS, and 5 PPMS), mean age 42.

Curcumin mediates attenuation of pro-inflammatory interferon γ and interleukin 17 cytokine responses in psoriatic disease, strengthening its role as a dietary immunosuppressant.

Curcumin exhibits anti-inflammatory properties and has been used for centuries in traditional medicine and as dietary supplement. Data from clinical trials has strengthened the notion that curcumin may exert an anti-inflammatory and immunosuppressive role in patients with psoriatic disease, but its mode of action has remained elusive. We hypothesized that curcumin could inhibit interferon (IFN)-γ and interleukin (IL)-17 production in peripheral blood mononuclear cells from patients with psoriasis and psoriatic arthritis (PsA).

From Broca and Wernicke to the Neuromodulation Era: Insights of Brain Language Networks for Neurorehabilitation.

Communication in humans activates almost every part of the brain. Of course, the use of language predominates, but other cognitive functions such as attention, memory, emotion, and executive processes are also involved. However, in order to explain how our brain "understands," "speaks," and "writes," and in order to rehabilitate aphasic disorders, neuroscience has faced the challenge for years to reveal the responsible neural networks.

On the immunoregulatory role of statins in multiple sclerosis: the effects on Th17 cells.

Statins, the cholesterol-lowering drugs, also possess immunomodulatory properties, affecting among others T cell activation and differentiation, antigen presentation, and regulatory T cell (Tregs) maintenance and differentiation. Their effects on autoagression have led investigators to assess their clinical significance in autoimmune disease, such as multiple sclerosis (MS), a chronic progressive demyelinating disease of autoimmune nature. The dysregulated immunity noted in MS features a profound shift from Tregs dominance to Th17 cell superiority.
