RESUMEN
BACKGROUND: Chronic neurological disease such as multiple sclerosis (MS), is a significant risk factor for psychological distress, which can result in suicidal behaviour. Suicidal ideation (SI) is considered a harbinger of suicide-related mortality. However, so far, little is known about the role of protective factors against SI in MS. OBJECTIVE: This study aims to assess the association between coping self-efficacy and SI when controlled for sociodemographic variables, clinical variables, sleep-related problems, and depression. METHODS: The study sample consisted of 162 people with MS, was predominantly female (75.9 %), the mean age was 40.9 ± 11.4 years, the mean disease duration was 11.7 ± 7.1 years, and the mean functional disability score was 3.55 ± 1.1. We used the Coping Self-Efficacy scale (CSE), the General Health Questionnaire-28 (GHQ-28), the Expanded Disability Status Scale (EDSS), the Hospital Anxiety and Depression Scale (HADS), the Pittsburgh Sleep Quality Index (PSQI), and the Multidimensional Fatigue Inventory (MFI). Multiple linear regressions were utilized to statistically analyse the data. RESULTS: All assessed coping self-efficacy dimensions were significantly associated with SI in MS when controlled for sociodemographic variables, clinical variables, sleep-related problems, and depression. Furthermore, all assessed coping self-efficacy dimensions were able to alleviate the negative association between income, depression and SI. CONCLUSION: People with MS may significantly benefit from psychological support aimed at promoting coping self-efficacy and utilization of various coping strategies. Problem-focused coping, coping focused on getting support, and coping focused on stopping unpleasant thoughts and feelings seem to have comparable associations with SI, and thus interventions aimed at empowering any of these dimensions may be beneficial in diminishing the severity of SI.

Background and Objectives: Neurofilament light chain (NfL) is a sensitive biomarker of neuroaxonal damage. This study aimed to assess the relationship between the annual change in plasma NfL (pNfL) and disease activity in the past year, as defined by the concept no evidence of disease activity (NEDA) in a cohort of multiple sclerosis (MS) patients. Materials and Methods: Levels of pNfL (SIMOA) were examined in 141 MS patients and analyzed in relationship to the NEDA-3 status (absence of relapse, disability worsening, and MRI activity) and NEDA-4 (NEDA-3 extended by brain volume loss ≤ 0.4%) during the last 12 months. Patients were divided into two groups: annual pNfL change with an increase of less than 10% (group 1), and pNfL increases of more than 10% (group 2). Results: The mean age of the study participants (n = 141, 61% females) was 42.33 years (SD, 10.17), and the median disability score was 4.0 (3.5-5.0). The ROC analysis showed that a pNfL annual change ≥ 10% correlates with the absence of the NEDA-3 status (p < 0.001; AUC: 0.92), and the absence of the NEDA-4 status (p < 0.001; AUC: 0.839). Conclusions: Annual plasma NfL increases of more than 10% appear to be a useful tool for assessing disease activity in treated MS patients.

Background and Objectives: Post-stroke cognitive impairment (PSCI) has been defined as all problems in cognitive function that occur following a stroke. Studies published thus far on the prevalence of PSCI and post-stroke dementia (PSD) have shown conflicting estimates. The aim of this study was screening for cognitive impairment (CogI) in patients with an ischaemic stroke and finding the relationship between CogI (and its changes) and cardiovascular risk factors and imaging procedures-CT/MRI. Materials and Methods: We prospectively included patients with an ischaemic stroke admitted in the period from October 2019 to May 2022. In this period, 1328 patients were admitted, 305 of whom met the established inclusion criteria and underwent an examination of cognitive functions using the Montreal Cognitive Assessment (MoCA). Of these, 50 patients appeared for the control examination after 6 months. Results: In the retested group, CogI at discharge was diagnosed in 37 patients (74%). In follow-up testing after 6 months, CogI was present in 30 patients (60%). Only arterial hypertension (OR: 15; 95% CI; Pearson r: 0.001), lower education level (less than 13 years) (OR: 9.7; 95% CI 2.0-48.5; Pearson r: 0.002), and higher age were significantly associated with CogI after stroke. Conclusions: We established the prevalence of CogI and its course after 6 months in a well-defined group of patients after a mild ischaemic stroke (mean NIHSS: 2 and mean mRS: 1 at the discharge). Our results show that the prevalence of CogI after an ischaemic stroke at discharge is relatively high (74%), and it tends to be a spontaneous reduction. Cognitive functions were changed in 35% of patients. The definition of PSCI was completed in only 24% of individuals. Only an examination several months after a stroke can give us more accurate information about the true prevalence of persistent CogI after a stroke.

Introduction: The aim of our study was to determine whether the severity of the COVID-19 pandemic affected the quality of acute care of stroke. Methods: Data from the stroke register at the National Health Information Centre were analysed. Clinical data from two time periods (the first wave: March-April 2020; the second wave: October-November 2020) were compared using an independent sample t-test and the Wilcoxon-Mann-Whitney two sample rank-sum test. Results: The total number of patients admitted with stroke during the second wave of COVID-19 was 1848, versus 1698 in the first wave. The proportion of patients treated by IVT was similar in both waves (275 (20.7%) vs 333 (22.1%), p = 1, difference in location: -0,0003, 95% CI: -5.0 to 5.95). We found no difference in time from the onset of symptoms to treatment (median = 130 min in both waves, p = 0.52, difference in location: 3.99, 95% CI: -6.0 to 14.0), nor in the door-to-needle time (median = 29 vs 30 min, p = 0.08, difference in location: -2.99, 95% CI: -5.0 to 0.008) between the first and the second waves of the pandemic. We found no difference in NIHSS (median = 3 vs 4, p = 0.51, difference in location: 0.00007, 95% CI: -0.9 to 0.000006) and mRS (median = 3 in both waves, p = 0.60, difference in location: -0.00004, 95% CI: -0.00004 to 0.00003) at discharge from hospital between the two periods. Conclusion: The severity of the COVID-19 outbreak did not affect the quality of acute stroke care in Slovakia.
RESUMEN
BACKGROUND AND OBJECTIVES: The severity of multiple sclerosis (MS) varies widely among individuals. Understanding the determinants of this heterogeneity will help clinicians optimize the management of MS. The aim of this study was to investigate the association between latitude of residence, UV B radiation (UVB) exposure, and the severity of MS. METHODS: This observational study used the MSBase registry data. The included patients met the 2005 or 2010 McDonald diagnostic criteria for MS and had a minimum dataset recorded in the registry (date of birth, sex, clinic location, date of MS symptom onset, disease phenotype at baseline and censoring, and ≥1 Expanded Disability Status Scale score recorded). The latitude of each study center and cumulative annualized UVB dose at study center (calculated from National Aeronautics and Space Administration's Total Ozone Mapping Spectrometer) at ages 6 and 18 years and the year of disability assessment were calculated. Disease severity was quantified with Multiple Sclerosis Severity Score (MSSS). Quadratic regression was used to model the associations between latitude, UVB, and MSSS. RESULTS: The 46,128 patients who contributed 453,208 visits and a cumulative follow-up of 351,196 patient-years (70% women, mean age 39.2 ± 12 years, resident between latitudes 19°35' and 56°16') were included in this study. Latitude showed a nonlinear association with MS severity. In latitudes <40°, more severe disease was associated with higher latitudes (ß = 0.08, 95% CI 0.04-0.12). For example, this translates into a mean difference of 1.3 points of MSSS between patients living in Madrid and Copenhagen. No such association was observed in latitudes <40° (ß = -0.02, 95% CI -0.06 to 0.03). The overall disability accrual was faster in those with a lower level of estimated UVB exposure before the age of 6 years (ß = - 0.5, 95% CI -0.6 to 0.4) and 18 years (ß = - 0.6, 95% CI -0.7 to 0.4), as well as with lower lifetime UVB exposure at the time of disability assessment (ß = -1.0, 95% CI -1.1 to 0.9). DISCUSSION: In temperate zones, MS severity is associated with latitude. This association is mainly, but not exclusively, driven by UVB exposure contributing to both MS susceptibility and severity.

AIM OF THE STUDY: To investigate in a cross-sectional study the correlations of optical coherence tomography (OCT) with clinical and magnetic resonance imaging (MRI) parameters in multiple sclerosis (MS) patients. MATERIAL AND METHODS: OCT parameters include the peripapillary retinal nerve fibre layer (pRNFL) and ganglion cell complex (GCC). Brain magnetic resonance volumetry (T2- and T1- lesions volume, whole brain volume and grey matter volume) was evaluated using the Icobrain program. Clinical data was compared according to the history of optic neuritis (HON). Correlations were determined between OCT parameters and demographic (age, gender), clinical (disease duration, Expanded Disability Status Scale score [EDSS]), and MRI data. RESULTS: Out of 83 recruited people with MS, 27 had HON. The mean age of 75 patients with non-ON eyes was 42.08 ± 10.36 years, and 70.67% of the sample were females. Significant correlations were found between pRNFL and disability, along with several brain MRI-volumetry variables (Fluid-attenuated Inversion Recovery lesions volume [FLAIR]; T1-hypointense lesions volume; T1-lesions volume change; T1-volume lesions enlarging; whole brain volume; whole brain volume normative percentile; and volume of periventricular lesions). Multivariable linear regression analysis showed that age, pRNFL and GCC were significantly associated with T1-hypointense lesions volume change (the model explained 24% of the overall variance of the dependent variable). CONCLUSIONS: The pRFNL value correlates with disability and brain MRI-volumetric parameters in MS patients, serving as a useful neurodegeneration and inflammation surrogate marker.

BACKGROUND: Neurofilament light chain is a promising biomarker of disease activity and treatment response in relapsing-remitting multiple sclerosis (MS). Its role in progressive MS is less clear. AIM: The aim of the study was to assess the relationship between plasma neurofilament light chain (pNfL) and disease activity as defined by the concept NEDA-3 (No Evident Disease Activity), and brain volumetry, in a cohort of patients with the progressive disease form (PMS). METHODS: Levels of pNfL (SIMOA technology) were examined in 52 PMS patients and analysed in relationship to NEDA-3 status and annual brain volume loss (BVL) during the last 12 months. The statistical model was developed using logistic regression analysis, including demographic, clinical and magnetic resonance imaging (MRI) data as independent variables. Dependent variables were NEDA-3 status and BVL. RESULTS: The mean age of the study participants (n=52, 50% females) was 45.85 (SD, 9.82) and the median disability score was 5.0 (IQR: 5.0-5.5). ROC analysis showed that pNfL predicts NEDA-3 (the sensitivity and specificity of the model were 77.8% and 87.6%, respectively, P<0.001) and abnormal BVL (the sensitivity and specificity were 96.6% and 68.2%, respectively, P<0.001). CONCLUSIONS: The results show that pNfL levels are a useful biomarker of disease activity determined by NEDA-3 status, including brain MRI-volumetry, in patients with the progressive form of MS.

PURPOSE: Multiple sclerosis (MS) is a chronic disorder with a variable course. The aim of our study was to find out whether cognitive event-related potentials are prognostic for patient disability at the 15-year follow-up. METHODS: In the observed cohort of patients with MS, we examined the event-related potentials at baseline (2003). Functional status (Expanded Disability Status Scale score) was then assessed 15 years later, and the prognostic model was developed using binary logistic regression analysis. The independent variables included demographic (age, sex, and education), clinical (disability in 2003), radiologic (MRI lesion load), and event-related potentials parameters. The prognostic accuracy of the proposed model was evaluated by calculating the area under the receiver-operating characteristics curve. RESULTS: The study sample consisted of 85 patients with MS. The mean age was 35.5 (SD, 11.2) years, and the median disability score was 3.0 (1-7) in 2003 and 5.0 (1.5-9.5) in 2018. The significant prognostic factors of poor Expanded Disability Status Scale are higher baseline Expanded Disability Status Scale, longer MS duration, and prolonged P300 latency. The sensitivity and specificity of the cutoff at 5.0 for the disability score were 94% and 89%, respectively, with the area under the receiver-operating characteristics curve 0.94 (95% confidence interval, 0.889-0.984; P < 0.001). CONCLUSIONS: The results show that out of event-related potentials, the P300 wave latency is a prognostic of long-term disability progression in patients with MS.

INTRODUCTION: There is a need for blood biomarkers of disease activity in multiple sclerosis (MS). The aim of the study was to assess the relationship between plasma neurofilament light chain (pNfL) and disease activity as defined by the concept three-domain no evident disease activity (NEDA-3). METHODS: Levels of pNfL (SIMOA) were examined in 159 MS patients and analyzed in relationship to NEDA-3 status (absence of relapse, disability score worsening, and brain magnetic resonance activity) during the last 12 months. The accuracy of the proposed model was evaluated by calculating the area under the receiver operating characteristics (ROC) curve. From the pNfL cutoff, we evaluated the NEDA-NfL status (no relapse, no Expanded Disability Status Scale [EDSS] worsening, and pNfL below the cutoff value). RESULTS: Levels of pNfL were significantly higher in MS patients than in healthy controls (p < 0.001). From a total of 159 patients, 80 (50.3%) achieved NEDA-3 status, while 79 (49.7%) patients showed evident disease activity (EDA) status. pNfL were significantly lower in the NEDA-3 group than in the EDA group (pNfL mean 7.06 pg/mL [standard deviation (SD) 2.37] vs. pNfL mean 13.04 pg/mL [SD 7.07]) (p < 0.001). ROC analysis showed that pNfL predicts NEDA-3 status (sensitivity and specificity were 80.5 and 72.7%, respectively, p < 0.001), and NEDA-NfL predicts NEDA-3 status (sensitivity and specificity were 97.1 and 82.9%, respectively, p < 0.001). CONCLUSION: The results show that pNfL levels are a useful biomarker of disease activity determined by NEDA status in patients with MS and could be an alternative to brain magnetic resonance investigation.

BACKGROUND AND PURPOSE: A few studies using data from regional databases have recently pointed to a decreased number of patients with stroke. The aim of the present study was to describe country-level data (the number of patients with stroke, the proportion of patients with acute stroke and transient ischemic attack (TIA), the proportion of patients treated with intravenous thrombolysis [IVT] or mechanical thrombectomy [MT], the door-to-needle times [DNT], and the onset-to-needle time [ONT]) during the COVID-19 pandemic in Slovakia. METHODS: The study examined data from the stroke register at the National Health Information Centre. Data from three time periods (March to April 2020; March to April 2019; January to February 2020) were compared using an independent samples t-test and the Wilcoxon-Mann-Whitney two-sample rank-sum test. RESULTS: The number of stroke patients admitted to hospitals in Slovakia during the COVID-19 period showed a decrease (1673 vs. 2328 in period 2 and 2155 in period 3). The proportions of patients with TIA remained the same in periods 1 and 2 (9.7% vs. 11.7%) and in periods 1 and 3 (9.7 vs. 11.8%). The percentage of patients treated with IVT during the pandemic (22.4%) did not differ from period 2 (20.0%) or period 3 (21.4%). No difference was found in the rate of MT between the COVID-19 period (10.2%) and the same period in 2019 (10.7%) and in January to February 2020 (13.1%). The median DNT remained unchanged in periods 1 (30 min), 2 (35 min) and 3 (30 min), and no differences were found in median ONT in periods 1 (130 min), 2 (130 min) and 3 (140 min). CONCLUSION: We found a decreased number of stroke patients during the COVID-19 outbreak in Slovakia, but no evidence of a change in the quality of acute stroke care.

Fatigue and poor sleep quality are among the most common patient-reported problems associated with multiple sclerosis (MS). Social support, on the other hand, is often found to be positively associated with quality of life in patients with neurological diseases. Studies also show that suicidal ideation (SI) levels in MS are elevated compared to the general population. Thus, the aim of this study is to assess the associations between fatigue, social support, and SI in patients with MS. Out of 184 MS patients asked to participate in this cross-sectional study, 156 agreed (RR 69.8%; 75% female; mean age: 39.95 ± 9.97 years). Patients filled-in the Multidimensional Fatigue Inventory-20, the Pittsburgh Sleep Quality Index, the Multidimensional Scale of Perceived Social Support and the subscale of the General Health Questionnaire-28 focused on assessing SI. Models were controlled for age, gender, disease duration, functional disability, and sleep quality. Data were analyzed using multiple linear regressions. SI was positively associated with lower sleep quality and four types of fatigue: general, mental, reduced activity, and reduced motivation (p < 0.05). Physical fatigue was not significantly associated with SI. Social support was negatively associated with SI in all models. The final models under study explained from 24.3 to 29.7% of the total variance in SI. SI yielded associations with both sleep quality and fatigue, with the exception of physical fatigue. Information provided by physicians on sleep management, and a psychosocial intervention focused on people who provide support for patients with MS (family, friends, and significant others) may reduce levels of SI.
RESUMEN
OBJECTIVE: An increase in the incidence of narcolepsy after the pandemic influenza with the H1N1 vaccination in 2009 resulted in an interest in narcolepsy epidemiology. The aim of the study was to examine the incidence and prevalence rates of narcolepsy and to describe the associated characteristics in Slovakia. METHODS: Epidemiology data were calculated for each year from 2000 to 2017 based on records found in specialized centres. In sum, 61 narcoleptic patients were diagnosed, of which 51 (84%) had narcolepsy type 1 (NT1). Clinical data and results of polysomnography (PSG), Human Leukocyte Antigen (HLA)-typing, hypocretin (HCRT)-1 levels and body mass index (BMI) were summarised and evaluated for NT1 and narcolepsy type2 (NT2). Later, 244 sex and age matched controls were chosen to evaluate the comorbid diagnoses. RESULTS: The prevalence of narcolepsy in 2017 in Slovakia was 10.47 (CI 95% 8.26-14) cases/million inhabitants, and the mean incidence rate (2000-2017) was 0.57 (CI 95% 0.4-0.74) cases/million inhabitants. Narcoleptic patients were comorbid with arterial hypertension (17%), ischemic heart disease (8%), dyslipidaemia (18%), diabetes mellitus type 2 (10%), cardiac arrhythmia/atrial fibrillation (5%), autoimmune disorders (20%), allergy (11%), malignancy (3%), headache (15%) and mental disorders (20%). Patients with narcolepsy showed double the excess prevalence in mental disorders (OR 2.15, p < 0.05), and dyslipidaemia (OR 2.22, p < 0.05). The presence of autoimmune disorders and allergy showed a mild increase in the narcolepsy group (OR 1.46, resp. 1.63). Hashimoto thyroiditis (HT) was the most frequent autoimmune disorder. CONCLUSIONS: Narcolepsy is a rare disorder in Slovakia. From the phenotype, genetic characteristics and comorbidities the disorder does not vary from other European countries.

The aim of the presented study was to reveal the frequency of insomnia spells in E200K genetic Creutzfeldt-Jakob disease (gCJD) patients. Clinical records of 22 subjects diagnosed with E200K gCJD were retrospectively reviewed. The patients w/wo insomnia (n = 4, 18%/n = 18, 82%) did not differ in age, sex and the duration of the symptomatic phase. Analysis of the clinical features in the groups yielded differences in the clinical signs in the early phase of the disorder, proportion of homozygotes (Met/Met) at codon 129, MRI changes in the thalamus and the typical EEG abnormality. The study suggests that apart from traditional clinical features, the insomnia is not a rare early symptom in phenotype of E200K gCJD based on early thalamic involvement.

B-cell chronic lymphocytic leukemia (B-CLL) is the most common lymphoproliferative disorder in adults. Patients with B-CLL strongly express the CD23 - C type of lectin (low affinity IgE receptor, Fc epsilon RII), which is linked to B cell activation and proliferation. Phosphorylation in lymphocytes is tightly associated with regulation of protein activities, functional regulation and cell signaling, and may thus affect initiation and/or progression of the disease. Here we report changes in the phosphorylation of CD23 on threonine (pThr314) and two serine residues (pSer254, pSer265) in B lymphocytes of B-CLL patients, using a flow cytometry approach. The majority of tested patients with active forms of B-CLL presented a notable overexpression of CD23 along with pThr314, pSer254, and pSer265 CD23 phosphorylation positivity. Moreover, we have experimentally stimulated the CD23 phosphorylations in a subset of peripheral blood lymphocytes of healthy controls by phorbol-12-myristate-13-acetate treatment. This affects the activation of competent phosphorylation mediating kinases, resulting in the enhanced phosphorylation pattern. Together, these data confirm that CD23 protein is phosphorylated in B cells of B-CLL patients, report the identification of new CD23 phosphorylation sites, and suggest a possible role(s) of such phosphorylations in the activation of CD23 during the process of lymphocytic activation in B-CLL.

Patients with multiple sclerosis (MS) engage in various coping behaviours in order to manage their disease. The aim of this study is to find out if the self-esteem of patients is associated with coping strategies - problem-focused (e.g. making a plan of action when confronted with a problem); emotion focused (e.g. get emotional support from community); and focused on stopping unpleasant emotions and thoughts (e.g. keeping oneself from feeling sad), and if it can enhance or hinder coping efforts in the disease management. We collected data from 155 consecutive MS patients who completed the Coping Self-Efficacy Scale (CSE) and the Rosenberg Self-esteem Scale (RSE). Explained variance for problem-focused coping, emotion-focused coping, and coping focused on stopping unpleasant emotions and thoughts was 33, 24, and 31%, respectively. Self-esteem seems to be associated with coping strategies indicating that feelings of self-worth are linked with the ability to handle difficult life situations and can be helpful in chronic disease management.

Poor sleep is a serious burden for patients with multiple sclerosis (MS). The aim of this study is to assess whether the association between sleep quality and disability in MS patients is direct or mediated by depression, pain, and fatigue. We collected data from 152 patients with MS who filled out the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, the Multidimensional Fatigue Inventory and one item of the Short Form-36 regarding pain. The relationship between poor sleep and disability was found to be indirect, mediated by depression (p < 0.05), pain (p < 0.001) and physical fatigue (p < 0.01). Treatment of sleep disturbances may have beneficial effects beyond improving sleep. It may reduce depression, pain, and physical fatigue, which in turn may lessen disability.

The aim of this study is to explore whether different coping strategies are able to mediate the association between Type D personality and quality of life. We collected information from 156 consecutive patients (response rate: 72.9%; 75.0% women; median age: 40 ± 3 years). Patients completed the Type D Scale-14, the Coping Self-Efficacy Scale and the Short-Form Health Survey for measuring physical and mental quality of life. The mediating effect of coping was analysed using correlations, linear regressions and the Sobel z-test. In the mental quality of life, all three studied coping strategies mediated the association between Type D personality and quality of life.

The aim of this study is to explore whether self-esteem and social participation are associated with the physical and mental quality of life (Physical Component Summary, Mental Component Summary) and whether self-esteem can mediate the association between these variables. We collected information from 118 consecutive multiple sclerosis patients. Age, gender, disease duration, disability status, and participation were significant predictors of Physical Component Summary, explaining 55.4 percent of the total variance. Self-esteem fully mediated the association between social participation and Mental Component Summary (estimate/standard error = -4.872; p < 0.001) and along with disability status explained 48.3 percent of the variance in Mental Component Summary. These results can be used in intervention and educational programs.

OBJECTIVES: Most of the psychological and physical factors associated with poor sleep quality in patients with multiple sclerosis (MS) have a different prevalence in women and men, but whether or not these factors contribute differently to sleep quality in women and men with MS remains unclear. The aim of this study was to identify possible gender differences in factors related to poor sleep quality in MS patients. MATERIAL AND METHODS: We collected data from 153 patients with MS. Patients filled out the Pittsburgh Sleep Quality Index (PSQI), the Hospital Anxiety and Depression Scale, and one item of the Short Form-36 regarding pain. RESULTS: The best model of predictors of poor sleep quality consisting of gender, depression, anxiety, pain, and the interaction between gender and pain showed that the only variable interacting with gender, which was significantly associated with poor sleep quality was pain (odds ratio [OR] for interaction of pain with male gender was 15.4, 95% CI: 2.4; 39.5). Separate models for men and women consisting of pain, depression, anxiety, after adjustment for age, disease duration, and disability showed that pain was the only variable associated with poor sleep quality in men (OR = 12.7, 95% CI: 1.9; 29.6), whereas depression (OR = 4.1, 95% CI: 1.3; 13.2) and anxiety (OR = 6.8, 95% CI: 2.4; 19.1) were in women. CONCLUSIONS: Factors contributing to poor sleep quality in MS patients differ by gender. Depression and anxiety are associated with poor sleep quality in women, whereas pain is in men. This highlights the need to apply gender-specific approaches to the treatment of sleep disorders.
