Evolving migraine management: Lithuania's telemedicine experience.

Introduction: COVID-19 challenges have underscored the potential of telemedicine in migraine management. This study focuses on assessing patients' telemedicine experience for headache management in Lithuania and identifying key barriers and facilitators for its wider use. Methods: A nationwide e-survey was conducted in 2023 via the Lithuanian Association of Migraine Patients' website, social media platforms, websites of public and private healthcare facilities, and migraine self-help groups. The survey covered sociodemographics, migraine characteristics, previous experience with teleconsultations for headaches with neurologists and general practitioners (GP), perceived advantages and disadvantages of telehealth, and preferred future consultation types. Results: Eight hundred and forty seven respondents with a confirmed migraine diagnosis were analyzed. The majority were female (97.2%), with a median age of 35 (IQR 30-42) years and an average of 5 (IQR 3-9) monthly headache days (MHDs). 7.0% of respondents had chronic migraine (CM). Prior teleconsultations for headaches were reported by 35.2% of respondents, 26.2% with a GP and 17.0% with a neurologist (p < 0.0001). Teleconsultation outcomes included continuation of a prescribed treatment (84.7% for GPs and 83.3% for neurologists, p = 0.7295), initiation of new acute medications (12.2% for GPs with 70.4% reported as effective and 27.1% for neurologists with 84.6% effective, p = 0.0005 and p < 0.0001, respectively). Reasons for not undergoing remote neurology consultations: the lack of inquiry (69.7%), unavailability from neurologists (18.1%) and respondent's opposition to remote consultations (12.2%). Patients evaluated their experience with remote neurology services better than that of GPs (p = 0.0289). 67.3% of respondents preferred a mixed-mode approach for future consultations. In-person-only preference (29.0%) correlated with multiple factors, including history of remote primary neurology consultations (OR 5.89, p = 0.0022), lower education (OR 2.20, p = 0.0001), physically demanding work (OR 1.95, p = 0.0001), and number of drawbacks in telemedicine identified (OR 1.30, p < 0.0001), and worse experience of a prior remote GP consultation (OR 0.704, p < 0.0001). The main indicator of preference for remote-only consultations was the perception of fewer telemedicine disadvantages (OR 0.503, p = 0.0007). Conclusions: Our findings confirm that telemedicine contributes to effective migraine management and is used limitedly in Lithuania. Despite one-third of respondents having experienced teleconsultations, significant barriers remain. Our study highlights a clear preference for a hybrid consultation type.

Association between Left Atrial Appendage Morphology and Clot Histology in Patients with Embolic Ischemic Stroke: An Exploratory Study.

BACKGROUND: Acute embolic ischemic stroke poses a significant healthcare challenge. Histological clot features' variability among patients with acute ischemic stroke treated by mechanical thrombectomy has potential implications for determining treatment and etiology. This study investigated the clot histological feature differences among patients who experienced cardioembolic stroke and embolic stroke of undetermined source with different left atrial appendage (LAA) morphologies. METHODS: We conducted a prospective observational study involving 79 patients with acute embolic ischemic stroke undergoing mechanical thrombectomy. Computed tomography angiography images were used to classify LAA morphologies. An artificial intelligence algorithm assessed the clot fibrin and red blood cell contents. RESULTS: Patients with chicken-wing LAA morphology exhibited lower mean clot fibrin proportions than did those with non-chicken-wing morphology (p < 0.001). Linear regression analysis showed that chicken-wing LAA was significantly associated with a lower clot fibrin proportion (estimate, -0.177; 95% CI [-0.259, -0.096]; p < 0.001). The successful recanalization rate and first-pass effect between the groups did not differ significantly. CONCLUSIONS: The chicken-wing LAA morphological type is associated with lower clot fibrin contents, suggesting potentially different embolism mechanisms or diverse embolic sources, compared with the non-chicken-wing LAA types. Further studies are required to investigate this association.

Case report: Late onset type 3 hemiplegic migraine with permanent neurologic sequelae after attacks.

This case study describes a 57-year-old woman with a six-year history of recurrent episodes characterized by visual, sensory, speech disturbances, hemiparesis and severe one-sided headaches accompanied by fever and altered consciousness. Initially misdiagnosed as a stroke, the atypical disease course and MRI findings led to additional genetic testing which revealed a sodium voltage-gated channel gene mutation (T1174S), confirming a diagnosis of sporadic hemiplegic migraine. The migraine prophylaxis showed some improvement in episode frequency and severity. Despite an initial improvement, the patient underwent severe cognitive decline and developed new permanent neurological symptoms during the subsequent 7 years of follow-up.

Accuracy of migraine diagnosis and treatment by neurologists in the Baltic states: e-survey with clinical case challenge.

BACKGROUND: Underdiagnosis of migraine causes a significant health burden, including lower quality of life, excessive medication use, and a delay in effective treatment. The purpose of this study was to evaluate migraine diagnosis accuracy and to review the treatment approaches used by neurologists in the Baltic states. METHODS: The research was conducted as an anonymous e-survey with four cases in March and April 2021. RESULTS: 119 practicing adult neurologists have participated. The migraine diagnostic accuracy was 63.2%. The most commonly used diagnostic criteria were moderate/severe pain, unilateral pain, and disruption of daily activities. Diagnostic accuracy did not differ significantly between neurologists who always use ICHD-3 criteria and those who don't (68.4% vs. 58.5%, p = 0.167). It was higher in neurologists who were working in headache centers (91.7% vs. 60.9%, p = 0.012), and was related to a higher percentage of migraine diagnoses in all consulted headache patients (R2 = 0.202, adjusted R2 = 0.195, p < 0.001), prophylaxis with onabotulinumtoxin A [OR = 4.332, 95% Cl (1.588-11.814)], and anti-CGRP monoclonal antibodies [OR = 2.862, 95% Cl (1.186-6.907)]. CONCLUSIONS: Migraine diagnostic accuracy is improved through practical patient counseling and modern treatment prescription. Although the neurologists in the Baltic states follow current European guidelines, there is room for improvement in diagnostic accuracy to reduce migraine burden.

COVID-19 pandemic: Impact of quarantine on migraine and patients' care in Lithuania.

OBJECTIVE: there is a scarcity of data regarding the long-term (one year or more) impact of COVID-19 related quarantine on migraine burden. The aim of this cross-sectional study was to assess the impact of quarantine on migraine course, and the implications of a shift in migraine patients' care. METHODS: An anonymous online survey of 206 migraine patients in Lithuania was undertaken in April 2021. RESULTS: During quarantine, 42.2% of respondents reported migraine worsening, 17.0% - migraine improvement, and 40.8% reported no change. The most common causes of improvement specified by respondents were improved sleep, increased physical activity, and better eating habits. The most common reasons for migraine worsening were decreased physical activity, use of masks and respirators, and anxiety about own health. Logistic regression revealed that the changes in migraine course were associated not only with the migraine severity and educational level, but also with lifestyle alterations such as changes in sleep, the use of personal protective equipment, and increased home workload. A quarter of respondents were unable to consult a doctor. Patients who failed this started using more analgesics (65.0% and 55.0%, p = 0.004). Almost one-third of consultations were conducted over the telephone. Treatment changes were more common during face-to-face than remote consultations (63.6% and 18.2%, p = 0.009), however, the efficacy of treatment changes did not differ significantly (61.9% and 50.0%, p = 0.741). CONCLUSION: we found an overall rise in migraine burden because of lifestyle changes during the COVID-19 related quarantine. Inability to visit a doctor led to the emergence of remote consultations.

Testing for Thrombophilia in Young Cryptogenic Stroke Patients: Does the Presence of Patent Foramen Ovale Make a Difference?

Background and Objectives: The diagnostic value of thrombophilia remains unknown in young patients with patent foramen ovale (PFO) and stroke. In this study we hypothesized that inherited thrombophilias that lead to venous thrombosis are more prevalent in patients with PFO. Materials and Methods: The study included patients of the tertiary center Vilnius University Hospital Santaros Klinikos who had a cryptogenic ischemic stroke between the ages of 18 and 50 between the years 2008 and 2021. Transient ischemic attacks were excluded. Contrast-enhanced transcranial Doppler ultrasound and extensive laboratory testing were performed. Results: The study included 161 cryptogenic stroke patients (mean age 39.2 ± 7.6 years; 54% female), and a right-to-left shunt was found in 112 (69.6%). The mean time between stroke and thrombophilia testing was 210 days (median 98 days). In total, 61 (39.8%) patients were diagnosed with thrombophilia. The most common finding was hyperhomocysteinemia (26.7%), 14.3% of which were genetically confirmed. Two patients (1.2%) were diagnosed with factor V Leiden mutation, three patients (1.9%) with prothrombin G20210A mutation, one patient (0.6%) had a protein C mutation and one patient (0.6%) had a protein S mutation. No antithrombin mutations were diagnosed in our study population. A total of 45.5% of patients with inherited thrombophilia had a right-to-left shunt, while 54.5% did not, p = 0.092. Personal thrombosis anamnesis was positive significantly more often in patients with antiphospholipid syndrome. Conclusions: The hypothesis of the study was rejected since inherited venous thrombophilia was not significantly more common in patients with PFO. Due to the rarity of thrombophilias in general, more research with a larger sample size is required to further verify our findings.

Risk factors for development of personal protective equipment induced headache: e-survey of medical staff in Baltic states.

BACKGROUND: The COVID-19 pandemic led to an unprecedented increase in the use of personal protective equipment (PPE) among medical personnel. The goal of this study was to determine the risk factors and frequency of PPE-induced headache during the COVID-19 pandemic. METHODS: From January 25 to March 1, 2021, an anonymous online survey was undertaken in the Baltic states. RESULTS: In total, 2132 individuals participated. 52.3% experienced a PPE-induced headache. Usual onset time was between 2-3 h, lasting up to 1 h after PPE removal. The most common localization was in temporal and frontal regions. Headache usually occurred 2 to 3 days per week with an average pain score of 5.04 ± 1.80 points. Higher risk was associated with discomfort/pressure OR = 11.55, heat stress OR = 2.228, skin conditions OR = 1.784, long PPE use (duration 10-12 h) OR = 2,18, headache history prior PPE use OR = 1.207. Out of 52.3% respondents with PPE-induced headache, 45.5% developed de novo headache, whereas 54.5% had headache history. Statistically significant differences of PPE-induced headache between respective groups included severity (4.73 vs 5.29), duration (≥ 6 h 6.7% vs 8.2%), accompanying symptoms (nausea (19.3% vs 25.7%), photophobia (19.1% vs 25.7%), phonophobia (15.8% vs 23.5%), osmophobia (5.3% vs 12.0%)) and painkiller use (43.0% vs 61.7%). CONCLUSIONS: Over half of the medical personnel reported headache while using PPE. The risk was higher in individuals with headache history, increased duration of PPE use and discomfort while using PPE. Predisposed individuals reported PPE-induced headache which persisted longer, was more intense and debilitating than in the respondents with de novo headache.

Obesity and the Risk of Cryptogenic Ischemic Stroke in Young Adults.

OBJECTIVES: We examined the association between obesity and early-onset cryptogenic ischemic stroke (CIS) and whether fat distribution or sex altered this association. MATERIALS AND METHODS: This prospective, multi-center, case-control study included 345 patients, aged 18-49 years, with first-ever, acute CIS. The control group included 345 age- and sex-matched stroke-free individuals. We measured height, weight, waist circumference, and hip circumference. Obesity metrics analyzed included body mass index (BMI), waist-to-hip ratio (WHR), waist-to-stature ratio (WSR), and a body shape index (ABSI). Models were adjusted for age, level of education, vascular risk factors, and migraine with aura. RESULTS: After adjusting for demographics, vascular risk factors, and migraine with aura, the highest tertile of WHR was associated with CIS (OR for highest versus lowest WHR tertile 2.81, 95%CI 1.43-5.51; P=0.003). In sex-specific analyses, WHR tertiles were not associated with CIS. However, using WHO WHR cutoff values (>0.85 for women, >0.90 for men), abdominally obese women were at increased risk of CIS (OR 2.09, 95%CI 1.02-4.27; P=0.045). After adjusting for confounders, WC, BMI, WSR, or ABSI were not associated with CIS. CONCLUSIONS: Abdominal obesity measured with WHR was an independent risk factor for CIS in young adults after rigorous adjustment for concomitant risk factors.

Successful treatment of primary headache associated with sexual activity using erenumab: Case report.

BACKGROUND: Primary headache associated with sexual activity is a rare benign headache disorder that is provoked by sexual excitement. It is a diagnosis of exclusion after the underlying secondary causes have been ruled out. The cause of this headache disorder is still unknown. Cerebral vasospasm, pericranial muscular contraction, hemodynamic and respiratory changes during sexual activity are most commonly listed as possible pathophysiological mechanisms. Several acute and prophylactic options with good clinical response have been described in the case series. CASE REPORT: We present a case of a 30-year-old woman with primary headache associated with sexual activity and comorbid with frequent episodic migraine without aura. Both headache disorders were successfully managed with monoclonal antibody against calcitonine gene-related peptide (CGRP) receptor erenumab 70 mg. CONCLUSION: The efficacy of erenumab in our case presumes that CGRP might also be an important mediator in facilitating primary headache associated with sexual activity.

Patient-reported outcomes of migraine treatment with erenumab: results from a national patient survey.

BACKGROUND: Despite development of new therapies, migraine remains an undertreated illness. It is important to understand patients' preferences and perceptions of using a certain therapy. We present data from a nationwide Lithuanian survey of patients' experience using erenumab for the treatment of high frequency episodic and chronic migraine. METHODS: An anonymous internet survey was distributed on February-March 2021 to the members of Migraine Association of Lithuania. All adult respondents who reported using at least one dose of erenumab were included in the study. RESULTS: Out of 145 respondents, 75.2% had chronic migraine, and 31.7% had medication overuse headache. Patients received an average of 6 (IQR 4-9) erenumab doses. 93.1% respondents found erenumab effective, and 72.6% experienced improvement during the first month. MHDs were reduced by 9.8 (SD 6.0) (P < 0.001), and MMDs by 7.2 (SD 5.2) days (P < 0.001). 78.6% respondents achieved ≥ 50% reduction and 47.6% achieved ≥ 75% reduction of MMDs. 13.8% patients indicated a wearing-off effect during the treatment course, and 37.8% - some wearing-off between injections. Constipation was the most frequent adverse event (32.6%). 47.2% of patients who had a positive erenumab effect and discontinued treatment experienced migraine rebound in 6 (SD 2.0) weeks. CONCLUSION: Erenumab is perceived as an effective and safe treatment. Further studies are needed to investigate a post-cessation deterioration of achieved improvement. HIGHLIGHTS: • Vast majority of patients experience stable or increasing effect of erenumab. • Erenumab efficacy usually becomes evident during the first month of treatment. • Erenumab is perceived significantly better than non-specific preventive medications. • Almost 40% of patients experienced some wearing-off between injections. • Almost half of patients experience migraine rebounds after treatment cessation.

De novo Migraine with Aura in the Third Trimester of Pregnancy: A Case Report and Literature review.

BACKGROUND: Among all headache disorders, migraine has the highest prevalence during gestation. The majority of migraineurs experience improvement during pregnancy, but a few may experience migraine for the first time. This poses a diagnostic challenge in the differential diagnosis between primary and life-threatening secondary headache disorders. Because pregnancy itself is an independent risk factor for secondary headache disorders, it is mandatory to exclude these conditions in order to diagnose migraine. There is a large body of literature about pre-existing migraine course during pregnancy and its link with adverse pregnancy outcomes, but there are no studies examining these aspects among women with new-onset migraine during pregnancy. CASE REPORT: A 31-year-old female at 33 weeks of gestation (gravida 2, para 2) was referred to the neurologist eds disturbances, which were followed by pressing severe headache, rated as 8 out of 10 on a numeric rating scale and accompanied by dizziness. The headache lasted for one day, and dizziness continued to the following day. The patient was investigated for a secondary headache disorder, but laboratory and neuroimaging results were unremarkable. A migraine with aura was diagnosed. The patient was advised to keep a consistent sleep schedule, maintain regular low physical activity, eat regularly and take magnesium supplementation. The patient was informed about a safe treatment approach in case of an acute attack. At 40 weeks of gestation the patient delivered female newborn, weighing 3750g, with Apgar scores of 8 and 9 (due to a nuchal cord). The postpartum period was uneventful. During the subsequent 4 years, the patient did not experience any recurrent migraine attacks and had no pregnancies. CONCLUSION: In order to diagnose a migraine during pregnancy, exclusion of secondary headache disorders is mandatory. Pregnant migraineur should be regularly monitored for adverse birth outcomes. It is essential to educate patients, provide information about the safe treatment of migraine attacks, and explain nonpharmacological prevention and supplementation benefits.

Subspecialty training of neurology residents and junior neurologists in the Baltic States.

BACKGROUND: Neurology is a field of increasing subspecialization. There is no published data regarding the proportion of neurology subspecialists in the Baltic States. The aim of this cross-sectional study was to identify factors associated with neurology subspecialty choice, to examine possible differences between neurology residents' and junior neurologists' view of subspecialty, and to assess perceived subspecialty acquisition opportunities and subspecialty attractiveness. METHODS: The research was conducted as an anonymous online survey between December 28, 2020, and January 24, 2021 of neurology residents and neurologists who completed their residency during the last 5 years in the Baltic States. RESULTS: In total, 72 residents and 65 neurologists participated. "Cerebrovascular diseases" and "multiple sclerosis and autoimmune diseases of the nervous system" were rated as the two most attractive subspecialties by residents, whereas "headache" and "clinical neurophysiology" were the most attractive among junior neurologists. "Vertigo and dizziness" and "dementia" were ranked the least attractive among both groups. "Cerebrovascular diseases" were perceived as having the most acquisition opportunities. The two most common determinants of subspecialty choice were "medical content of the subspecialty" and "influence of mentor during undergraduate studies or residency". CONCLUSIONS: Two-thirds of junior neurologists subspecialize in at least one subspecialty, and one-third of residents are already determined to pursue subspecialty training. Junior neurologists rated most outpatient-related subspecialties as more attractive than neurology residents. Between the Baltic States' universities, there was a significant difference in the number of residents who were determined to pursue subspecialty training.

Validation and Factor Analysis of the Lithuanian Version of the Dizziness Handicap Inventory.

OBJECTIVES: This study aimed to validate the Lithuanian version of the Dizziness Handicap Inventory (DHI-L), investigate its reliability, and perform factor analysis. MATERIALS AND METHODS: A standard protocol of translation was followed for psychometric instruments. A total of 108 patients (75.9% women), mean age 51.9 years, with peripheral or central dizziness and vertigo participated in our cross-sectional study. The internal consistency was measured by Cronbach's alpha coefficient and corrected item-total correlations (CI-TCs). After a week, 65 of the recruited patients were again asked to fill out Dizziness Handicap Inventory (DHI)-L to ascertain test-retest reliability (intraclass correlation, ICC). Concurrent validation was performed using Pearson correlation between the total score and subscales of DHI-L and the eight scales of Short Form-36 Health Survey (SF-36). Finally, the factor structure of the DHI was assessed by principal component analysis (PCA). RESULTS: The Cronbach's alpha coefficient was very high (0.91). CI-TCs for DHI-L total scale ranged from 0.33 to 0.67. The correlations between DHI and SF-36 were high to weak. The ICC was excellent for the total score and its subscales. Our proposed two-factor model explained 44.5% of the variance. The first factor indicated disability in daily activities and psychological effect of handicap. The second factor comprised of items that pertained to postural instability. CONCLUSION: The DHI-L has shown good reliability and validity. Results did not support the original subscale structure of the DHI. As more studies need to be done to restructure DHI, we recommend only using the total DHI score as a measure of dizziness handicap.

Association of aortic stiffness, carotid intima-media thickness and endothelial function with cardiovascular events in metabolic syndrome subjects.

PURPOSE: The objective of this study was to assess predictive value of various arterial markers for cardiovascular (CV) events in patients with metabolic syndrome (MetS). MATERIALS AND METHODS: A longitudinal study with the follow-up period of 3.9 ± 1.7 years investigated 2728 middle-aged (53.9 ± 6.2 years old, 63% women) MetS subjects without overt CV disease. The study cohort was comprised of the participants of the Lithuanian High Cardiovascular Risk primary prevention program. The baseline assessment included the evaluation of brachial flow-mediated dilatation (FMD), carotid intima-media thickness (cIMT), carotid stiffness index, aortic pulse wave velocity (aPWV), aortic augmentation index (AIx), and cardio-ankle vascular index). The data on the cardiovascular outcome (fatal or non-fatal myocardial infarction or stroke) was collected by using the databases of the two major national registries. RESULTS: Over the follow-up period, 83 (3%) patients had at least one cardiovascular event. In a univariate analysis, occurrence of CV events was associated with the following parameters: higher mean blood pressure, aPWV, AIx and cIMT, and lower FMD (all p < .05). In Cox proportional hazard regression analysis, the occurrence of CV event was associated with an increase in aPWV (HR 1.29, 95% CI 1.04-1.60, p = .019), AIx (HR 1.53, 95% CI 1.16-2.02, p = .003), and cIMT (HR 1.31, 95% CI 1.14-1.50, p < .001), and with the decrease in FMD (HR 0.83, 95% CI 0.71-0.97, p = .016) even after the adjustment for age, gender, and common cardiometabolic risk factors. In a two-level survival trees analysis, we established that patients with cIMT > 794 mcm had higher CV risk (p < .001) and their prognosis was further compromised by aPWV > 11.1 m/s (p = .023). Meanwhile, in patients with cIMT ≤ 794mcm, the FMD cut-off point of 6.5% further stratified the risk (p = .003). CONCLUSIONS: In our prospective study, CV risk in the middle-aged patients with MetS was associated with an increase in cIMT and aPWV, and with a decrease in FMD.

Diagnosis and treatment choices of suspected benign paroxysmal positional vertigo: current approach of general practitioners, neurologists, and ENT physicians.

PURPOSE: Benign paroxysmal positional vertigo (BPPV) is a frequently underdiagnosed cause of vertigo, potentially due to the underuse of diagnostic and therapeutic canalith repositioning procedures (CRPs). We aimed to investigate self-reported use of the diagnostic and therapeutic approach to BPPV patients by Lithuanian neurologists, ear, nose, and throat (ENT) physicians, and general practitioners (GPs), and to explore potential reasons for the underuse of the maneuvers. METHODS: Neurologists, ENT physicians, and GPs were invited to complete a written questionnaire focused on diagnostic and therapeutic practices related to BPPV. Between-group differences and associations between responses were analyzed statistically. RESULTS: In total, 97 neurologists, 85 ENT physicians and 142 GPs (21.1%, 26.8%, and 5.7%, respectively, of all corresponding licensed Lithuanian physicians) completed the questionnaire. 24% of neurologists, 33% ENT physicians and 50% GPs do not perform diagnostic maneuvers for patients with suspected BPPV, and 28%, 61%, and 84%, respectively, do not perform CRPs. Years of clinical experience was a negative predictor of CRP performance [OR 0.97 (95% CI 0.95-0.99), p = 0.001]. Frequent reasons for not performing CRPs were time taken for the procedure, fear of provoking symptoms, and lack of knowledge. All physicians frequently ordered additional imaging or consultations for suspected BPPV and reported prescribing a range of medications. CONCLUSIONS: A significant proportion of Lithuanian neurologists, ENT physicians, and GPs do not employ diagnostic maneuvers and CRPs for BPPV patients, contrary to established guidelines. Lack of expertise and time available is a common culprit that leads to unnecessary drug prescribing and investigation.

Migraine-linked characteristics of transcranial magnetic stimulation-induced phosphenes.

Transcranial magnetic stimulation is used to explore visual cortex hyperexcitability in migraine. We hypothesized that the phosphene threshold in subjects suffering from migraines with and without aura would be lower than in controls, and this phenomenon could be linked to higher pain and disability levels. We also implied that subjects with lower phosphene threshold could see more phosphenes of different colors and shapes. Our primary objective was to compare the phosphene threshold between migraine without aura, migraine with aura, and control groups and investigate which factors contribute to different phosphene parameters in migraineurs. Secondary objectives were to compare color, shape, and number of phosphenes between groups and assess pain and disability level correlation with the phosphene characteristics. Phosphene threshold in migraine without aura, migraine with aura, and control groups were 68 ± 9.5% vs. 75 ± 12%, vs. 80 ± 11%, respectively. Other phosphene parameters (number, color and shape) did not differ between groups. Average pain level during the attack did not correlate with phosphene threshold significantly, though the non-significant trend for negative correlation of migraine disability assessment scale score and a phosphene threshold has been found the higher was migraine disability assessment scale value, the lower was phosphene threshold (ß = -0.255; P = 0.139). Other variables: gender, age, migraine subtype, migraine duration and use of hormone contraceptives - were not related to the phosphene threshold value. Our study provides additional data on visual cortex hyperexcitability in migraineurs, regarding transcranial magnetic stimulation with a figure-of-eight coil. Visual cortex excitability might be linked to higher disability.

Aerobic Training Effect on Arterial Stiffness in Metabolic Syndrome.

BACKGROUND: Metabolic syndrome, physical inactivity, and central obesity contribute to early vascular aging, which leads to increased risk of cardiovascular disease. This study aimed to assess the effect of heart rate (HR)-targeted aerobic exercise training on the indices of early vascular aging, in particular, arterial stiffness, and on anthropometric and clinical profile of metabolic syndrome subjects. METHODS: There were 126 metabolic syndrome subjects randomly selected. Anthropometric parameters, blood pressure (BP), blood sample, and arterial wall functional and structural parameters were obtained prior to and after the 8-week (84 patients) supervised training program. The age- and sex-matched control group (42 patients) followed the same protocol, except for the HR-targeted training program. RESULTS: In the study group, HR-targeted training was associated with decreased aortic pulse wave velocity (8.47 ± 1.40 vs 8.01 ± 1.06 m/s; P = .005), HR (P < .001), systolic (P < .015) and diastolic (P < .004) BP, waist circumference (P < .004), total and low-density-lipid cholesterol (respectively, 6.42 ± 1.41 vs 5.89 ± 1.32, P = .003 and 4.2 ± 1.18 vs 3.8 ± 1.21, P = .002), and an increase in aerobic capacity (P < .001). In the control group there were no statistically significant changes of arterial stiffness parameters. Multivariate analysis revealed that reduction of arterial stiffness was BP dependent. CONCLUSIONS: In subjects with metabolic syndrome, HR-targeted exercise training is associated with BP-dependent decrease in aortic stiffness and improvement of metabolic and fitness parameters.

Clinical characteristics and overuse patterns of medication overuse headache: Retrospective case-series study.

According to Eurolight project's results, frequency of medication overuse headache in Lithuania is similar to other European countries. However, data on the characteristics of the disorder is lacking. OBJECTIVE: The aim was to analyze clinical characteristics and overuse patterns of patients with medication overuse headache. PATIENTS AND METHODS: Retrospective study was conducted in out-patient department of university hospital. 57.0% of the patients were from Vilnius and 43.0% from other cities and districts of Lithuania. Medical histories of patients consulted by headache specialist on private (86.2%) or public basis from 2008 to 2015 were analyzed. Diagnoses prior to 2013 were revised according to ICHD-III beta criteria. Overuse patterns were calculated only for patients with migraine. RESULTS: 87 patients (90.8% female) with mean age of 43.78 years were included in the study and 67 of them had primary diagnosis of migraine. Mean duration of overuse was 4.00 years. Mean headache frequency was 24.11days per month. Triptans more often were overused by younger patients (p=0.049). 41.8% of migraine patients with MOH overused triptans, 38.8% simple, and 38.8% combination-analgesics. 1 (1.5%) patient overused ergotamines, 7.5% were poly-overusers and no pure opioid overuse was found. Among patients with migraine most common overused medications were sumatriptan (38.8%), caffeine containing combination-analgesics (35.8%) and ibuprofen (20.9%). CONCLUSION: Triptans were most commonly overused drugs among patients with migraine. Fairly frequent overuse of combination-analgesics for migraine should raise concern.

Skin Autofluorescence in Systemic Sclerosis Is Related to the Disease and Vascular Damage: A Cross-Sectional Analytic Study of Comparative Groups.

Skin autofluorescence (AF), a relatively simple and time saving procedure, measures the accumulation of advanced glycation end (AGE) products. The importance in autoimmune rheumatic diseases, particularly, systemic sclerosis (SSc), has not been evaluated yet. The aim of our study was to examine the skin AF in the context of SSc patients and to analyse the relations between skin AF and other surrogate measures of atherosclerosis. Forty-seven patients with SSc and 47 healthy volunteers were included in this study as controls. Patients and controls underwent common carotid artery wall assessment, arterial stiffness and wave reflection measurements, laser Doppler measurements of capillary flow, assessment of endothelial function by brachial ultrasound, peripheral arterial tonometry, and AGE measurement by skin AF. Wall properties of the common carotid arteries and wave reflection measurements were not affected in these study patients compared to controls while measures reflecting small capillary flow were altered. The accumulation of AGE products measured by skin AF was more prominent in SSc patients than in healthy controls. AGE products' score was significantly associated with carotid radial pulse wave velocity, intima media/carotid artery diameter ratio, capillary flow percentage change during occlusion, and the disease itself in a multivariate linear analysis model.
