Objective Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system affecting patients' well-being and quality of life. Pythagorean Self-Awareness Intervention (PSAI) is a novel non-pharmaceutical intervention with significant benefits both in MS and other chronic diseases. In this study, the longstanding effectiveness of PSAI was investigated. Method This was a two-arm quasi-experimental pragmatic trial in relapsing–remitting MS patients (23 in the PSAI and 21 in the control group). PSAI patients received an 8-week training period and then they performed PSAI at home for another 16 weeks. Assessments took place at baseline, 8 weeks, and 24 weeks. These included cognition, fatigue, perceived stress, and hair cortisol. Results Significant group × time interactions favoring PSAI were found during the first 8-week period for information processing speed, fatigue, and perceived stress. However, only verbal memory was found to be significantly improved in the PSAI group during the 24-week follow-up period. There were no significant group × time differences with respect to hair cortisol. No side effects were noted and compliance was excellent. Conclusions PSAI was mostly effective during the first 8-week training period. Its benefits worn out during the non-training period, albeit we observed a delayed significant improvement of verbal memory. Our findings will help to further refine the technique, either by extending the training period and/or by including booster sessions, throughout the PSAI treatment. This study provided Class III evidence for PSAI. [ABSTRACT FROM AUTHOR]

There is apt evidence in favor of a significant association between sleep and mortality. So far, most studies examine sleep problems using comprehensive, time-consuming tools and questions. In this study, we investigated the ability of four simple "yes" or "no" answered questions (i.e. easiness to fall asleep, restful upon awakening, sleep satisfaction and presence of insomnia) to predict 12-year all-cause and cardiovascular mortality in a rural population of 1519 citizens. The sample consisted of 652 males and 867 females, with a mean age of 56.9 years old (range 15-102 years old). Age, gender, education, smoking, body mass index and health status were used as confounders in the Cox proportional hazard models. 293 (19.3%) deaths were recorded. After adjusting for confounders, difficulty to fall asleep was significantly related to an increased risk of cardiovascular death in smokers (aHR 3.71, 95% CI 1.01-13.62). Male individuals, not feeling restful upon awakening were at a significantly increased risk of all-cause (aHR 2.08, 95% CI 1.33-3.24) and cardiovascular mortality (aHR 6.24, 95% CI 1.90-20.49), in the latter case only if they were non-smokers. Smokers, not satisfied with their sleep, were at a significantly increased risk of cardiovascular death (aHR 5.44, 95% CI 1.73-17.09). The presence of insomnia significantly increased the risk of all-cause mortality (aHR 8.10, 95% CI 1.66-39.57) in smokers of basic education and cardiovascular mortality (aHR 26.68 95% CI 4.78-148.49) in smokers. In conclusion, simple sleep questions can predict mortality, at least in rural populations. Future studies should expand these results to other populations. [ABSTRACT FROM AUTHOR]

Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19) explores optimally impact of MS on sexual activity/satisfaction/intimacy. The present study aims to provide the only validation of the Greek Version of MSISQ-19, and compare results to validation studies in other languages. The original/English version of the MSISQ-19 was translated into Greek according to standardized guidelines, while validity/reliability, correlations with other scales and sexual dysfunction prevalence were tested. Subjects were requested to complete all questionnaires and MSISQ-19, being re-tested three weeks later. Construct-validity of the Greek version of the MSISQ-19 was confirmed with principal-component-analysis. Bartlett's test assessed correlation-adequacy between items. Pearson's correlation explored internal-construct-validity between subscales and overall score, and external–construct-validity with disease-status variables, cognitive testing and patient-reported outcomes regarding fatigue, depression/anxiety, MS impact, and quality of life. 201 PwMS (130 female). Mean age was 39.3 ± 11.8 years with median disease-duration 11.7 ± 7.9 years. 79.1% RRMS, PPMS (10.4%) and SPMS (10.4%). Cronbach's alpha coefficient was 0.949. MSISQ-19 correlations between items were large. Significant associations of sexual dysfunction were identified with age (rho = 0.392, p < 0.01), years of education (rho=–0.199, p = 0.006), the Expanded Disability Status Scale (rho = 0.518, p < 0.01) and MS duration (rho = 0.354, p < 0.01). Correlations were disclosed with the Brief International Cognitive Assessment for MS (rho=-0.247, p < 0.05), Modified Fatigue Impact Scale (rho = 0.374, p < 0.05), Depression Anxiety Stress Scale (rho = 0.375, p < 0.05), Multiple Sclerosis Impact Scale (rho = 0.442, p < 0.05), and EuroQoL-five-dimensional instrument (rho = 0.375, p < 0.05). Internal consistency of the Greek version of the MSISQ-19 was confirmed with Cronbach's alpha. Test-retest reliability (31 PwMS) was excellent with intraclass-correlation-coefficients > 0.90. Besides Greek MSISQ-19 satisfactory validity/reliability/reproducibility and being first to include cognitive-testing, authors estimated sexual-dysfunction prevalence affecting half PwMS. This study provides the only validation of the Greek Version of the MSISQ-19. The latter was found with satisfactory validity, reliability and reproducibility. 50% of the Greek PwMS sample was found to be afflicted with sexual dysfunction. This is also the first validation study to examine associations with cognitive testing. Sexual function is still an underestimated functionality parameter upon examination. [ABSTRACT FROM AUTHOR]

Objective:Investigating the role of religiosity in mortality. Design:A retrospective cohort study (mean follow-up period 131.2 ± 30.8 months) in 1519 rural citizens in Greece (57.1% women, mean age 56.9 ± 20.4 years). Main outcome measures:Measurements included education, disease status, body mass index, lifestyle, sleep-quality and self-rated health (SRH). Religiosity was assessed as composite score of praying and church attendance. Cox proportional hazard models were used to calculate adjusted hazard ratios (aHR) for all-cause and cardiovascular mortality. Results:A total of 293 deaths were recorded, 59.2% of which had occurred due to cardiovascular diseases, followed by cancer diseases (17%). All-cause mortality was found increased for older people (aHR: 1.10, 95%CI: 1.08–1.11,p < .0001), for males (aHR: 1.44, 95%CI: 1.14–1.83,p = .002), for people reporting good SRH (aHR: .66, 95%CI: .51–.87,p = .003). Moreover, with increasing age the practice of regular exercise decreases all-causes mortality by approximately 3.5% by each year. Participants in the moderate category of religiosity were found to have decreased risk for all-cause mortality (aHR: .61, 95%CI: .46–.83,p = .001) compared to those in the low religiosity category. Cardiovascular mortality was also significantly associated with SRH and religiosity. Conclusion:Religiosity predicts mortality, in a rural population in Greece. Deciphering the mediators of religiosity and mortality relationship could facilitate future health policies. [ABSTRACT FROM AUTHOR]

Background: Cerebral venous sinus thrombosis (CVST) is a rare manifestation of thrombosis commonly caused by thrombophilia, hormonal-related factors, non-cerebral malignancy, and hematologic diseases. The aim of this review was to identify and summarize rare CVST cases. Methods: A literature search of the Medline database was performed in November 2022. CVST cases of a common cause were excluded. Demographic and clinical data were extracted. Eligible cases were categorized into inflammatory, primary CNS tumors, post-operative/traumatic, and idiopathic groups to allow statistical group comparisons. Results: 76 cases were analyzed. Idiopathic CVST was most frequently reported followed by inflammatory, post-traumatic/operative and primary CNS tumor causes. The intracranial hemorrhage rate was 23.7% and it was found to increase in the inflammatory group (45.8%). Anticoagulation was used in the majority of cases and it was significantly related to better outcomes. A low rate of anticoagulation use (43.8%) was found among CVST cases in the post-operative/traumatic group. The overall mortality rate was 9.8%. 82.4% of patients showed significant early improvement. Conclusions: Most rare CVST cases were either of idiopathic or inflammatory origin. Interestingly, hemorrhage occurred often he idiopathic CVST cases. A low rate of anticoagulation use in neurosurgical CVST cases after trauma or head surgery was observed. [ABSTRACT FROM AUTHOR]

Mothers of children with autism are subject to considerable stress by having to adjust to the disorder and to cope with practical and social issues. Evidence on the effects of relaxation training on stress of these mothers is scarce. The purpose of this pilot case-series study was to examine the role of a simple 6-week daily stress management technique on mothers of children with autism. Mothers' stress measurements and children's functionality were assessed using validated instruments. Participants were 11 mothers of children with autism seen consecutively in the autism clinic of a children's hospital. Statistically significant median reductions of perceived and parental stress were noted after the 6-week intervention. Median stress scores were lower by 37.1% and 33% from the baseline values of the perceived stress scale and parental stress index, respectively. Stress was not significantly correlated with children's functioning. Stress management seems to have benefits for mothers of children with autism. [ABSTRACT FROM AUTHOR]

There is a well-established adverse reciprocal relationship between stress and multiple sclerosis (MS). However, stress management in these patients has been parsimoniously studied. In this parallel randomized controlled trial, relapsing-remitting MS patients were randomly assigned to undergo either an 8-week stress management program (n = 31; relaxation breathing and progressive muscle relaxation, twice a day) or not (n = 30). Self-reported validated measures were used to evaluate perceived stress, health locus of control, anxiety, and depression. Daily diaries of MS symptoms were also kept by patients. In patients in the intervention group, perceived stress and symptoms of depression were significantly decreased after 8 weeks of relaxation. Repeated measures analyses showed significant group-by-time interactions for both the number of weekly symptoms and the mean intensity per symptom. No other significant change was reported. We deem that our results should encourage future studies that will incorporate more objective clinical and laboratory outcomes. [ABSTRACT FROM PUBLISHER]

Recent studies outline apoptosis of oligodendrocytes (OLDs) as an early event prior to the formation of the demyelinated plaque and post-translational modifications (PTMs) of myelin basic protein as characteristic processes of normal-appearing white matter in multiple sclerosis (MS). We reviewed reports using the following keywords: apoptosis, PTMs, autoimmunity and multiple sclerosis in all possible combinations. Introductory basic scientific information is included for the non-experts. Given the standard and ongoing studies, we raise the hypothesis that, at least in some cases, defective apoptosis of OLDs, early in the course of the disease, and post-translationally modified molecules lead to the activation of immune responses and eventually to autoimmunity. Autoimmune reactions and epitope spreading that take place in the course of the disease might obscure the initial events and leave most investigators blind to etiopathogenesis. Our paper outlines the need for studies at the very early stages of the disease, as well as sequential ones, in order to give us a valuable hint about the clarification of the cause(s) of the different clinical subtypes of MS.

The article presents a case study of a 75-year-old man who was presented with a history of fever, right facial palsy and progressive gait difficulty. A left sided hypoalgesia, absence of superficial abdominal reflexes, Babinski's reflex and right side lower limb weakness were observed. Spinal magnetic resonance imaging (MRI) showed two sites of occurrence of lesions and gadolinium induced enhancement on T1-weighted images.

Enzyme-inducing antiepileptic drugs AEDs have adverse effects on bone mineral density (BMD), whereas studies on levetiracetam (LEV), a nonenzyme-inducing agent, have showed conflicting results. The aim of this study was to further elucidate the role of LEV in bone health. A sample of forty-six patients with epilepsy (mean age: 35.7 years, range: 20.2–64.2 years, 39.1% males) on LEV monotherapy for at least one year (range: 1.5–14.5 years, median 5.5 years) underwent femoral neck (FN) and lumbar spine (LS) BMD measurements. The T- and Z-scores were calculated. Results showed that 15.2% of the patients were identified with osteopenia and none with osteoporosis. Pearson's correlations revealed a negative but not significant association of LEV duration with bone-related measurements (range of rhos: from − 0.004 to − 0.23), except for LS T-scores. In terms of FN BMD measurements, Z-scores, and T-scores, longer LEV therapy duration had adverse but not significant effects on bone health after adjusting for age and gender. With regard to LS BMD measurements, Z-scores, and T-scores, men taking LEV for at least 5.5 years had better, although not significant, bone health compared with men with shorter LEV exposure, after adjusting for age. The opposite was found in women, although differences did not reach significance. These preliminary results are indicative of a differential effect of LEV therapy duration in men and women, which could presumably account for the incongruity of the already published studies. Also, LS assessments were more sensitive to these gender differences. Future larger studies should validate these results. [ABSTRACT FROM AUTHOR]

Background: Pediatric-Onset Multiple Sclerosis (POMS) is considered a complex disease entity and several genetic, hormonal, and environmental factors have been associated with disease pathogenesis. Linkage studies in Caucasians have consistently suggested the human leukocyte antigen (HLA) polymorphisms, as the genetic locus most strongly linked to MS, with the HLA-DRB1*15:01 allele, being associated with both adult and pediatric MS patients. Here we aim to investigate the prevalence of the HLA-DRB1 alleles among a Hellenic POMS cohort and any possible associations with clinical and imaging disease features. Materials and methods: 100 POMS patients fulfilling the IPMSSG criteria, 168 Adult-Onset MS (AOMS) patients, and 246 Healthy Controls (HCs) have been enrolled. HLA genotyping was performed with a standard low-resolution sequence-specific oligonucleotide (SSO) technique. Results: POMS patients display a significantly increased HLA-DRB1*03 frequency compared to both HCs [24% vs. 12.6%, OR [95%CI]: 2.19 (1.21-3.97), p=0.016) and AOMS (24% vs. 13.1%, OR [95%CI]: 2.1 (1.1-3.98), p=0.034] respectively. HLA-DRB1*03-carriers display reduced risk for brainstem lesion development (OR [CI 95%]:0.19 (0.06-0.65), p=0.011). A significantly lower frequency of HLA-DRB1*07 (4% vs 13.4%, OR (95% CI): 0.27 (0.09-0.78), p= 0.017) and HLA-DRB1*11 (37% vs 52%, OR [95% CI]: 0.54 (0.34-0.87), p= 0.016) was observed in POMS compared to HCs. Conclusion: The HLA-DRB1*03 allele was associated with a higher risk for POMS, replicating our previous findings, and with a lower risk for brainstem lesion development, a common clinical and neuroimaging feature in POMS, while HLA-DRB1*07 and HLA-DRB1*11 display a protective role. These findings expand the existing knowledge of HLA associations and POMS. [ABSTRACT FROM AUTHOR]

Introduction: Chronic pain is increasingly recognized as part of long COVID syndrome, mainly in the form of myalgias. However, chronic pain has several forms, and according to our clinical experience, COVID-19 survivors suffer from numerous painful syndromes, other than myalgias. The aim of our study was to estimate the prevalence of chronic pain, describe the commonest painful syndromes and identify pain determinants in a random population of COVID-19 survivors. Methods: This was a cross-sectional study conducted at the Medical School, University of Cyprus. A random population of 90 COVID-19 survivors was recruited. Demographic and COVID-19 related clinical characteristics were recorded. The painDETECT and DN4 questionnaires were used to evaluate the painful syndromes. Results: The prevalence of chronic pain was estimated to be 63.3%. The most common site of pain was low back (37.8%), followed by joints (28.9%) and neck (12.2%). Patients with chronic pain compared to subjects without pain were older (50.5 ± 15.9 versus 42.2 ± 12.6, p = 0.011) and more likely to be female (71.9% versus 45.5%, p = 0.013). One in six subjects (16.7%) reported new-onset pain post COVID-19. The prevalence of neuropathic pain was estimated to be 24.4%. After adjusting for age and gender, headache during COVID-19 was a statistically significant predictor of neuropathic pain, increasing 4.9 times (95% 1.4–16.6, p = 0.011) the odds of neuropathic pain. Conclusion: Chronic pain—especially neuropathic—is widely prevalent in COVID-19 survivors. One in six subjects will develop new-onset pain that will persist beyond the acute phase of the disease and, therefore, should be considered a symptom of long COVID syndrome. [ABSTRACT FROM AUTHOR]

Background: Human Leucocyte Antigens (HLA) represent the genetic loci most strongly linked to Multiple Sclerosis (MS). Apart from HLA-DR and HLA–DQ, HLA-DP alleles have been previously studied regarding their role in MS pathogenesis, but to a much lesser extent. Our objective was to investigate the risk/resistance influence of HLA-DPB1 alleles in Hellenic patients with early- and adult-onset MS (EOMS/AOMS), and possible associations with the HLA-DRB1*15:01 risk allele. Methods: One hundred MS-patients (28 EOMS, 72 AOMS) fulfilling the McDonald-2010 criteria were enrolled. HLA genotyping was performed with standard low-resolution Sequence-Specific Oligonucleotide techniques. Demographics, clinical and laboratory data were statistically processed using well-defined parametric and nonparametric methods and the SPSSv22.0 software. Results: No significant HLA-DPB1 differences were found between EOMS and AOMS patients for 23 distinct HLA-DPB1 and 12 HLA-DRB1 alleles. The HLA-DPB1*03 allele frequency was found to be significantly increased, and the HLA-DPB1*02 allele frequency significantly decreased, in AOMS patients compared to controls. The HLA-DPB1*04 allele was to be found significantly decreased in AOMS and EOMS patients compared to controls. Conclusions: Our study supports the previously reported risk susceptibility role of the HLA-DPB1*03 allele in AOMS among Caucasians. Additionally, we report for the first time a protective role of the HLA-DPB1*04 allele among Hellenic patients with both EOMS and AOMS. [ABSTRACT FROM AUTHOR]

Introduction: The universality and complexity of pain, which is highly prevalent, yield its significance to both patients and researchers. Developing a non-invasive tool that can objectively measure pain is of the utmost importance for clinical and research purposes. Traditionally electroencephalography (EEG) has been mostly used in epilepsy; however, over the recent years EEG has become an important non-invasive clinical tool that has helped increase our understanding of brain network complexities and for the identification of areas of dysfunction. This review aimed to investigate the role of EEG recordings as potential biomarkers of pain perception. Methods: A systematic search of the PubMed database led to the identification of 938 papers, of which 919 were excluded as a result of not meeting the eligibility criteria, and one article was identified through screening of the reference lists of the 19 eligible studies. Ultimately, 20 papers were included in this systematic review. Results: Changes of the cortical activation have potential, though the described changes are not always consistent. The most consistent finding is the increase in the delta and gamma power activity. Only a limited number of studies have looked into brain networks encoding pain perception. Conclusion: Although no robust EEG biomarkers of pain perception have been identified yet, EEG has potential and future research should be attempted. Designing strong research protocols, controlling for potential risk of biases, as well as investigating brain networks rather than isolated cortical changes will be crucial in this attempt.

Background: REM-sleep behaviour disorder (RBD) is a parasomnia and a common comorbidity in Parkinson's disease (PD). There is evidence that the presence of RBD is associated with more severe PD. The differences in the clinical manifestations and the natural history are likely to imply underlying differences in the pathophysiology among PD patients with and without RBD. The increasing number of neuroimaging studies support this notion. Objective: Our primary objective was to review the current evidence regarding the brain neuroimaging findings in PD patients with RBD (PDRBD). Methods: A systematic review of articles, published in PubMed between January 1, 2000 and September 23, 2020 was performed. We evaluate previous studies that assessed PD patients with RBD using various brain structural and functional magnetic resonance imaging (MRI) techniques and brain nuclear medicine imaging. Results: Twenty-nine studies, involving a total of 3,347 PD subjects among which 912 subjects with PDRBD, met the selection criteria and were included. The presence of RBD in PD patients is associated with structural and functional alterations in several brain regions, mainly in brainstem, limbic structures, frontotemporal cortex, and basal ganglia, raising the hypothesis of a PDRBD neuroimaging phenotype. Conclusion: The current review provides up-to-date knowledge in this field and summarizes the neurobiological/neuroimaging substrate of RBD in PD. [ABSTRACT FROM AUTHOR]

Background: We aimed to describe the electrophysiological progression rate of chronic idiopathic axonal polyneuropathy (CIAP) and look into the potential role of human leukocyte antigen (HLA) genetic susceptibility in its development. Methods: We recruited 57 patients with CIAP (mean age at diagnosis 67, mean follow‐up 7 years). The assessments included clinical and electrophysiological data and HLA‐DQ genotyping. Results: The DQA1*05 allele was found more frequently in patients than in healthy controls (odds ratio, 1.96, P =.011). In patients with length‐dependent CIAP, a linear effect of time on the electrophysiological findings was found in the superficial radial (3.2% mean annual decrement, P <.001), sural (4.7% mean annual decrement, P =.002) and tibial nerve (6.1% mean annual decrement, P =.007) amplitudes, independently from age or gender. Conclusions: Patients with length‐dependent CIAP, show a linear progression over time. Interesting associations of HLA‐DQA1*05 allele with length‐dependent CIAP and non‐DQ2/DQ8 with idiopathic sensory ganglionopathy were found. These merit further investigation in larger cohorts and may suggest a role of the immune system in the pathogenesis of CIAP. [ABSTRACT FROM AUTHOR]

Objective: Gluten neuropathy (GN) is the term used to describe peripheral neuropathy that occurs in patients with gluten sensitivity (GS) or coeliac disease (CD) in the absence of other risk factors. We aimed to describe the neurophysiological progression rate of GN across time and look into the potential role of genetic susceptibility in its development. Methods: This is a cohort study of 45 patients with GN with a mean follow-up period of 8 ± 5 years. The assessments included clinical and neurophysiological data and HLA-DQ genotyping. Results: The mean age at diagnosis was 60 ± 12 years. The majority of patients had a length-dependent neuropathy (75.6%), whereas the rest were diagnosed with sensory ganglionopathy (SG). DQA1*02-positive patients were more likely to suffer with SG compared to the DQA1*02 negative patients (60% versus 13.8%, p = 0.009). There was also a trend for statistical significance regarding the DQB1*06 allele and the DQA1*01/DQB1*06 haplotype were found more frequently in patients with GN than in healthy controls (p = 0.026 and p = 0.047, respectively). A linear effect of time on the neurophysiological findings was found in radial sensory nerve action potential (1.9% mean annual decrement, p = 0.036), sural sensory nerve action potential (3.3% mean annual decrement, p = 0.013) and tibial nerve motor compound action potential (6.5% mean annual decrement, p < 0.001) amplitudes, independently from age or gender. Conclusions: GN is a late manifestation of GS and CD. The majority of patients have the length-dependent neuropathy with a linear deterioration over time. HLA genotyping of GS and CD patients who suffer from neuropathic symptoms is recommended as it can help identifying patients at risk for developing SG. [ABSTRACT FROM AUTHOR]

Objectives: The primary aim was to estimate the burnout prevalence among all medical students at the Medical School of the University of Cyprus. Secondary aims were to ascertain the predictors of burnout and its relationship with lifestyle habits, sleep quality and mental health. Background: Burnout in the healthcare sector has drawn significant scientific attention over the last few years. Recent research underscored the large burden of profession-related burnout among medical students. Materials and methods: An anonymous questionnaire was administered to all 189 eligible candidates. This included demographic and lifestyle characteristics. Sleep quality was assessed via the Pittsburg Sleep Quality Index, mental health was assessed via the mental health (MH) domain of the 36-item Short Form Health Survey (SF-36) and burnout with the Maslach Burnout Inventory–Student Survey (MBI-SS). Results: Overall response rate was 96.3%. The burnout prevalence was 18.1%. There was a significant linear effect of between the year of studies and the burnout frequency [F(1) = 5.09, p = 0.024], implying that with increasing academic year there were more students with burnout, especially after the 4th year of education which signifies the beginning of clinical education. Students with burnout were more likely to have poor sleep quality (90.9% vs. 60.8%, odds ratio 4.33, p = 0.023) and worse mental health (MH score 40.2 ± 17.7 vs 62.9 ± 20.3, p<0.001). Alcohol consumers had more symptoms of cynicism and less feelings of efficacy than non-alcohol consumers. Moreover, less feelings of efficacy were significantly associated with more alcohol consumption among alcohol consumers. Conclusions: Burnout is prevalent in medical students and increases significantly during the clinical years. Students with burnout have worse sleep and mental health and might use alcohol as a coping mechanism. Implementing prevention strategies of burnout may be beneficial. [ABSTRACT FROM AUTHOR]

BACKGROUND: Studies have shown that stress is implicated in the cause of neck pain (NP). OBJECTIVES: The purpose of this study is to examine the effect of a simple, zero cost stress management program on patients suffering from NP. METHODS: This study is a parallel-type randomized clinical study. People suffering from chronic non-specific NP were chosen randomly to participate in an eight week duration program of stress management (N = 28) (including diaphragmatic breathing, progressive muscle relaxation) or in a no intervention control condition (N = 25). Self-report measures were used for the evaluation of various variables at the beginning and at the end of the eight-week monitoring period. Descriptive and inferential statistic methods were used for the statistical analysis. RESULTS: At the end of the monitoring period, the intervention group showed a statistically significant reduction of stress and anxiety (p = 0.03, p = 0.01), report of stress related symptoms (p = 0.003), percentage of disability due to NP (p = 0.000) and NP intensity (p = 0.002). At the same time, daily routine satisfaction levels were elevated (p = 0.019). No statistically significant difference was observed in cortisol measurements. CONCLUSIONS: Stress management has positive effects on NP patients. [ABSTRACT FROM AUTHOR]

Abstract: Self-rated health (SRH) is an inclusive measure of public health that is correlated with quality of life and subsequent mortality. Extensive literature has identified multiple determinants of SRH in different populations. However, such studies on centenarians are scarce and parsimonious. Our objective is to identify SRH determinants in centenarians. This is a nationwide cross-sectional study on 400 Greek centenarians that was carried out between 2007 and 2010. SRH was evaluated by a simple question with a 5-point scale. Three categories of SRH were formed (very good/good/poor), which served as the dependent variable in multinomial regression models. Various sociodemographic, disease-related, lifestyle and psychosocial variables were assessed as candidate determinants of SRH. According to our results, SRH ratings among centenarians were better than that expected according to previous studies showing worse SRH ratings with increasing age in Greece. The 22.4% of the variance in SRH among centenarians was predicted by gender, habitat region and status, financial problems, disease presence and autonomy. Among lifestyle and psychosocial variables, obesity, good relationships with children, lack of feelings of loneliness, high optimism, adaptability and an internal health locus of control profile were independently associated with good SRH. These results indicate that SRH in individuals of extreme longevity were related to specific personal psychosocial factors that contribute to healthy aging and thus support the biopsychosocial model of health promotion.

Objectives: Long-term immunomodulatory therapy of pediatric onset-multiple sclerosis (POMS) is based mainly on published case series and internationally agreed guidelines. Relevant studies in the Greek population are absent from the literature. The purpose of this study is to present data on the efficacy and safety of the 1st line immunomodulatory drugs in the treatment of POMS patients. Materials and methods: The present study included 27 patients meeting the IPMSSG criteria for POMS and who are monitored at the outpatient clinic of the Multiple Sclerosis and Demyelinating Diseases Unit (MSDDU), of the 1st Neurological Department, University Hospital of Aeginition. All patients received 1st line immunomodulatory drugs as initial therapy. Clinical, laboratory, and imaging parameters of the disease were recorded before and after treatment. Results: Post-treatment, a significant reduction of the relapse number (mean ± SD: 2.0 ± 1.0 vs 1.2 ± 1.6, p = 0.002), EDSS progression (mean ± SD: 1.5 ± 0.8 vs 0.9 ± 0.7, p = 0.005) and ARR (mean ± SD: 1.5 ± 0.7 vs 0.4 ± 0.5, p = 0.0001) was observed, while no changes were observed in the EDSS score, (mean ± SD: 1.8 ± 0.6 vs 1.9. 0.6, p = 0.60). Advanced age at treatment initiation increased the risk for drug discontinuation before 24 months of therapy (HR = 0.6, 95% CI (0.35–0.99), p = 0.04). Conclusions: Most pediatric patients are forced to switch to either more efficacious 1st line or 2nd line drugs. Additionally, our study suggests that older age at the time of the 1st line treatment initiation, contributes to earlier drug discontinuation. [ABSTRACT FROM AUTHOR]

Background: Patients suffering from several neurologic disorders may bear the "stigma" of their disease, being disqualified from full social acceptance. Although stigma is considered to be present in Multiple Sclerosis (MS), the factors that influence its levels are ambiguous. Aim of our study was to examine, for the first time in the literature, the basic determinants of stigma in a Hellenic MS-patients cohort, as well as how stigma affects their Quality-of-Life (QoL) profiles.Methods: Three hundred forty two patients were recruited in this study. Data collected concerned sociodemographic and disease-related variables, mental illness assessment, Multiple-Sclerosis-QoL-54 (MSQoL-54) and Stigma-Scale-for-Chronic-Illness-24 (SSCI-24) questionnaires. Potential determinants were evaluated with univariate statistical analyses for their contribution to total, internalized (inner-self derived) and externalized (society derived) stigma. Important findings were further evaluated on hierarchical regression models.Results: Disability levels were found to be the most powerful predictor in all stigma categories, followed by the presence of mental illness. Working and caregiving status were also ascertained as determinants of internalized stigma. Stigma levels displayed strong negative correlation with all composites of MSQoL-54.Conclusions: Stigma is present in the social environment of MS patients and was confirmed as a barrier (according to the International Classification of Functioning, Disability and Health), with detrimental effects on their QoL levels and functioning performances. Disability and mental illness were shown as the principal determinants of stigma, while financial characteristics were not as equally involved. Further validation of these results in other MS populations may provide safer conclusions, towards more efficacious patient-centered care outcomes. [ABSTRACT FROM AUTHOR]

Background: Immunoglobulins (IG) are widely used for the treatment of a variety of immune-mediated diseases. The exact mechanism of action remains unknown, but IG modulate the expression and function of Fc receptors, interfere with complement activation and production of cytokines, neutralize pathogenic autoantibodies, and affect the activation and effector functions of B and T lymphocytes. Immunoglobulins are usually delivered intravenously, and are effective in ameliorating motor symptoms, and/or preventing disease progression in immune-mediated neuropathies, including Guillain–Barré syndrome and chronic inflammatory demyelinating polyneuropathy. Objective: The aim of this systematic review and meta-analysis was to study the potential of IG for the treatment of painful peripheral neuropathy (PPN). The outcome of interest was the percentage of patients with PPN who achieved pain relief following IG administration. Methods: We performed a systematic literature search on March 17, 2022, in the PubMed database without any publication date restrictions. We also looked for unpublished or ongoing trials in clinicaltrials.org. Pain reduction following IG treatment had to be within the aims (primary or secondary). Results: The aforementioned literature search strategy revealed five studies (two open-label, three randomized placebo-controlled) eligible to be included. The pooled estimate of the percentage of patients with PPN who received immunoglobulins and reported pain relief was found to be 65% (95% CI 58–71%). The likelihood of achieving pain relief with immunoglobulin treatment was 2.9 times higher (95% CI 1.6–5.2) compared to placebo (p = 0.0003). Conclusion: The use of IG for the treatment of pain due to peripheral neuropathy has a potential therapeutic benefit. Further studies across patients with different types of painful peripheral neuropathy are needed to better characterize this effect. Registration number on PROSPERO: CRD42022319614.

Restless Legs Syndrome (RLS) is a sleep‐related movement disorder, which can also result from brainstem pathology. A systematic review of articles published in the electronic databases PubMed and Web of Science was conducted to summarize the existent literature on RLS associated with a brainstem stroke. We identified eight articles including 19 subjects with RLS due to brainstem ischemic lesion. The symptoms occurred simultaneously with the infarction (66.7%) or few days after (33.3%). The most common location of infarction was pons and less commonly medulla. In most cases (68.4%), symptoms were unilateral. In the majority of those cases (92.3%), the contralateral limb was affected due to a lateral pons infarction. RLS symptoms after infarction improved or resolved in almost 90% of cases within a few days up to 3 months. In almost all patients who received dopaminergic treatment (11 out of 13, 91.7%), the symptoms improved significantly or resolved completely. Screening for RLS has to be considered in patients suffering a brainstem stroke, particularly anteromedial pontine infarction. The appearance of acute unilateral RLS symptoms, usually in association with other sensorimotor deficits, should prompt the clinician to consider a vascular event in the brainstem. RLS in these cases seem to have a favorable outcome and respond well to dopaminergic treatment. [ABSTRACT FROM AUTHOR]

Type I interferon (IFN-I) signalling represents a major target for modulation in a virus' bid for latency. IFN-I perturbations are also present in such as Alzheimer's disease (AD) and multiple sclerosis (MS), where viral infections are known to increase symptomatic burden. IFN-I modulation such as via IFNβ-1a, an established MS treatment, has been researched to a limited extent to both AD and COVID-19. In this mini review, we present emerging research on trained immunity as a pathogenetic basis for Alzheimer's disease and the emerging context for IFNβ-1a repositioning, via mechanisms shared with multiple sclerosis and induced by viral infections. • Type I interferon responses a perturbed in neurodegenerative disease and infection. • IFNβ etiologically restores canonical Type I interferon signalling in viral infection. • IFNβ-1α ameliorates neuroinflammation and cognitive decline in multiple sclerosis. • IFNβ-1α has shown efficacy in modulating hyperinflammation in COVID-19. • IFNβ-1α repositioning may be efficacious in Type I interferon signalling-driven cognitive decline.

Given the heterogeneity of Attention-Deficit Hyperactivity Disorder (ADHD), there is a constant need for proper diagnosis, employing more accurate, efficient, patient-friendly, and clinician-friendly tools. We developed a Greek version of the National Institute for Children's Health Quality (NICHQ) Vanderbilt ADHD Diagnostic Parent Rating Scale (VADPRS) for follow-up assessment and examined its reliability and validity. A total of 100 schoolchildren (65 girls and 35 boys) between 7 and 12 years old with ADHD were included in the study. The internal consistency and test–retest reliability were examined via principal component analysis. Three-component structure in our study accounts for 74.63% of the tool's variance. The questions' loadings onto the factors and the internal reliability of the three factors were satisfactory. Finally, the reliability of all factors presented was found adequately high, confirming the high internal consistency of the items. Our results suggest that the Greek version of the VADPRS-follow-up may be used as an accurate psychometric instrument for the purposes of diagnosing ADHD. Furthermore, the combined use of the VADPRS-follow-up with other widely accepted tools, such as the ADHD Rating Scale-IV, may present clinical utility in collating parent information concerning the behavioural phenotype of their children.

Background: The main goal of stress management and health promotion programs is to improve health by empowering people to take control over their lives. Daily health-related lifestyle choices are integral targets of these interventions and critical to evaluating their efficacy. To date, concepts such as self-efficacy, self-control and empowerment are assessed by tools that only partially address daily lifestyle choices. The aim of this study is to validate a novel measurement tool, the Healthy Lifestyle and Personal Control Questionnaire (HLPCQ), which aims to assess the concept of empowerment through a constellation of daily activities. Methods: Therefore, we performed principal component analysis (PCA) of 26 items that were derived from the qualitative data of several stress management programs conducted by our research team. Results: The PCA resulted in the following five-factor solution: 1) Dietary Healthy Choices, 2) Dietary Harm Avoidance, 3) Daily Routine, 4) Organized Physical Exercise and 5) Social and Mental Balance. All subscales showed satisfactory internal consistency and variance, relative to theoretical score ranges. Subscale scores and the total score were significantly correlated with perceived stress and health locus of control, implying good criterion validity. Associations with sociodemographic data and other variables, such as sleep quality and health assessments, were also found. Conclusions: The HLPCQ is a good tool for assessing the efficacy of future health-promoting interventions to improve individuals’ lifestyle and wellbeing. [ABSTRACT FROM AUTHOR]

Background and aim: Gluten neuropathy (GN) is a common neurological manifestation of gluten sensitivity (GS), characterized by serological evidence of GS, while other risk factors for developing neuropathy are absent. The degree of small fiber dysfunction in GN has not been studied in depth to date. Small fiber involvement may lead to pain, thermal perception abnormalities, and sweat gland dysfunction. Sudomotor innervation refers to the cholinergic innervation of the sympathetic nervous system through small fibers in the sweat glands. The aim of our study was to assess the sudomotor function of GN patients. Methods: Patients with GN were recruited. Clinical and neurophysiological data were obtained. HLA-DQ genotyping was performed. The skin electrochemical conductance (ESC) was measured with SUDOSCANTM. Results: Thirty-two patients (25 males, mean age 69.5±10.2 years) were recruited. Thirteen patients (40.6%) had abnormal sudomotor function of the hands. Sixteen patients (50%) had abnormal sudomotor function of the feet. Twenty-one patients (65.6%) had abnormal sudomotor function of either the hands or feet. Sudomotor dysfunction did not correlate with the type of neuropathy (length-dependent neuropathy or sensory ganglionopathy), gluten-free diet adherence, severity of neuropathy, and duration of disease or HLA-DQ genotype. No differences in the ESC were found between patients with painful and patients with painless GN. Conclusion: Sudomotor dysfunction affects two-thirds of patients with GN. The lack of correlation between pain and sudomotor dysfunction suggests different patterns of small fiber involvement in patients with GN. [ABSTRACT FROM AUTHOR]

The article discusses research which was conducted to investigate the role of the human leukocyte antigen (HLA) and DRB1 alleles in chronic inflammatory demyelinating polyneuropathy (CIDP) in Greek patients. Researchers evaluated 40 Greek CIDP patients. They found that there was a negative association between HLA and CIDP and that CIDP patients had higher frequencies of the DRB1 allele.

Stress plays an important role in major depressive disorder (MDD). Thus, a variety of stress management programs have been developed for people with this diagnosis. This is a pilot randomized clinical trial which implemented a holistic stress management program, Pythagorean Self-Awareness Intervention (PSAI) in adults with MDD, aiming to evaluate the effectiveness of PSAI compared to standard care for reduction of depressive symptoms (primary aim), improving mental health and quality of life (secondary aims). A total of 69 participants were randomized to an intervention group (N = 34), who received the usual care provided for patients with major depression and attended the PSAI program, and a control group (N = 35), who received the usual care only. Measurements were taken in both groups before and after the intervention and included: 1. Self-report questionnaires for measuring depressive symptoms, healthy lifestyle, perceived stress, anxiety, positive and negative affect and sleep quality, 2 Cognitive function assessment tools, 3. Hair and salivary cortisol. The intervention group demonstrated significantly greater reductions in depressive symptoms, negative affect, perceived stress, sleep quality and significantly greater increase in visual memory and healthy lifestyle compared to the control group. In addition, the intervention group demonstrated a significant reduction in first morning salivary cortisol, indicating a reduction in diurnal stress levels, while no significant change of salivary cortisol was observed in the control group. Finally, none of the study's groups demonstrated a significant change in hair cortisol concentration. In conclusion, PSAI can be applied to adults suffering from MDD with significant benefits for their mental health and quality of life. ClinicalTrials.gov Identifier: NCT04536714.

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system characterized by focal or diffuse inflammation, demyelination, axonal loss and neurodegeneration. Brain atrophy can be seen in the earliest stages of MS, progresses faster compared to healthy adults, and is a reliable predictor of future physical and cognitive disability. In addition, it is widely accepted to be a valid, sensitive and reproducible measure of neurodegeneration in MS. Reducing the rate of brain atrophy has only recently been incorporated as a critical endpoint into the clinical trials of new or emerging disease modifying drugs (DMDs) in MS. With the advent of easily accessible neuroimaging softwares along with the accumulating evidence, clinicians may be able to use brain atrophy measures in their everyday clinical practice to monitor disease course and response to DMDs. In this review, we will describe the different mechanisms contributing to brain atrophy, their clinical relevance on disease presentation and course and the effect of current or emergent DMDs on brain atrophy and neuroprotection.

Background: Over the past decades, the prevalence of obesity has markedly increased worldwide. Stress is recognized as a substantial contributor to increased body weight; therefore, stress management interventions, especially cognitive behavioural, are becoming increasingly popular. The impact of stress management on stress‐ and obesity‐related biomarkers (eg blood lipid profile, HBA1c, inflammatory biomarkers, such as CRP) has been scarcely studied. The aim of this study was to assess the effect of a novel cognitive behavioural stress management intervention, called 'Pythagorean Self‐Awareness Intervention' (PSAI), in overweight/obese adults. Materials and methods: This was a two‐armed 1:1 randomized, nonblind controlled study including overweight/obese individuals. The control group followed a personalized Mediterranean low‐calorie diet, and the intervention group followed the same diet in addition to the PSAI intervention for 8 weeks. Measurements included demographic, anthropometric (ie BMI, waist‐to‐hip ratio), stress (ie perceived stress, salivary cortisol), dietary behaviour (ie emotional eating) and metabolic parameters (ie blood lipid profile, HBA1c, CRP, body composition in fat and water). Outcome per‐protocol analysis was performed using mixed linear models adjusted for age and gender. Results: A total of 49 of 62 eligible adults were analysed in the study (there were three dropouts in the intervention group and 10 dropouts in the control group); 28 were assigned to the intervention group (mean age 54.7 ± 11.9 years) and 21 to the control group (mean age 51.8 ± 11.9 years). The intervention group showed a statistically significant decrease in perceived stress, cortisol concentrations 30 minutes after awakening, cortisol's area under the curve, BMI, waist‐to‐hip ratio, restrained, emotional and external eating behaviour, fasting glucose, LDL, triglycerides, HbA1c and body and trunk fat, compared with the control group. Based on the observed effect sizes, clinically meaningful changes may be more evident in stress perception, restrained and external eating behaviour, Hb1ac and trunk fat. The compliance to the PSAI intervention reached 100%, and there were no adverse effects. Conclusions: The PSAI technique may be an effective stress management method for overweight/obese adults. Future and larger randomized controlled studies are needed to allow generalization of these findings. [ABSTRACT FROM AUTHOR]

Literature supports a causal role of stress in major depressive disorder (MDD). Hair cortisol concentration (HCC) has been widely used as a measure of long-term stress. Although elevated HCC has been observed in healthy people experiencing chronic stress, findings regarding individuals with mental disorders have been complicated. This review attempts to systematically present all the published research on major depression and HCC. An extensive search of databases was performed to identify articles that investigated this question. The initial search retrieved 142 studies, of which, 16 original articles were included in this review. Results were contradictory; most of the studies showed no significant HCC differences between MDD patients and controls, while others indicated either higher or lower HCC in MDD patients than controls. Higher HCC was reported in first depressive episode compared to recurrent MDD and controls; patients with comorbid MDD and anxiety disorder had higher HCC than controls. No significant HCC difference was found between patients with melancholic or atypical depression and controls. Findings concerning HCC in postpartum depression were inconsistent. A meta-analysis of the data extracted from seven studies of the sample was performed to quantify the degree of cortisol change in MDD patients vs. controls. A random effects model revealed no significant hair cortisol concentrations difference between depressed patients and healthy controls (SMD: −0.02, 95% CI: −0.36 to 0.32). Significant heterogeneity was identified across included studies (P = 0.002, I2 = 71%). The disagreement among studies' results indicates that there is room for improvement in this research field. Confounding factors independent of depression should be taken into consideration. • Evidence on hair cortisol concentrations in major depression is inconsistent. • Meta-analysis revealed similar hair cortisol between depressed and healthy subjects. • Childhood trauma, anxiety and recurrence of depression may play a mediating role. • Hair cortisol in patients with melancholic/atypical depression is similar to controls. • Research in the field is limited and conclusions cannot be drawn with certainty.
