Abstract
Parkinson's disease (PD) is a degenerative disease of the central nervous system, of which patomechanizm entirely is not clear. In the picture neuropathologically there is observed degeneration and loss of dopaminergic neurons, but also noradrenergic, serotonergic and cholinergic neurons in patients with PD. It is believed, that causes of PD are both environmental and genetic factors, associated mainly with mutations in the SNCA and PRKN genes, which may lead to changes in the structure of proteins such as alpha-synuclein (ASN) and Parkin. In neurons, disorders of the protein structure can lead to its aggregation and formation of soluble oligomers and insoluble filaments in the form of Lewy bodies and Lewy neuritis. In PD aggregation of ASN can be modulated by many factors like: oxidative stress, other neuronal proteins, Parkin, catecholamines especially dopamine, and mutations of SNCA gene. It also appears that some impact on the aggregation of ASN may have destabilizing factors of ASN tetramers. That, does ASN may become a new point for pharmacotherapy in PD.

Abstract
Epinephrine (E) and sympathetic nerve stimulation were described by Thomas Renton Elliott in 1905 for the first time. Dopamine (DA), norepinephrine (NE), E, and serotonin (5-HT) belong to the classic biogenic amines (or monoamines). Parkinson's disease (PD) is among the diseases in which it has been established that catecholamines may account for the neurodegeneration of central and peripheral catecholamine neural systems. PD is a chronic and progressive neurological disorder characterized by resting tremor, rigidity, and bradykinesia, affecting 2% of individuals above the age of 65 years. This disorder is a result of degeneration of DA-producing neurons of the substantia nigra and a significant loss of noradrenergic neurons in the locus coeruleus. In PD and other related neurodegerative diseases, catecholamines play the role of endogenous neurotoxins. Catechol-O-methyltransferase (COMT) and/or monoamine oxidase (MAO) catalyze the metabolism of monoamines. However, the monoamine transporters for DA, NE, and 5-HT namely DAT, NET, and SERT, respectively regulate the monoamine concentration. The metabolism of catecholamines and 5-HT involves common factors. Monoamine transporters represent targets for many pharmacological agents that affect brain function, including psychostimulators and antidepressants. In PD, polymorphisms of the COMT, MAO, DAT, NET, and 5- HTT genes may change the levels of biogenic amines and their metabolic products. The currently available therapies for PD improve the symptoms but do not halt the progression of the disease. The most effective treatment for PD patients is therapy with L-dopa. Combined therapy for PD involves a DA agonist and decarboxylase, MAOs and COMT inhibitors, and is the current optimal form of PD treatment maintaining monoamine balance.

Abstract
Background The ExtaviJect® 30G autoinjector was developed to facilitate parenteral self-administration of interferon beta-1b (Extavia®), a first-line disease-modifying therapy in patients with multiple sclerosis. Our aim was to assess patient compliance with treatment when using the autoinjector, patients’ and nurses’ experiences of using the device, its tolerability, and patient satisfaction. Methods This was a 12-week, real-world, prospective, observational, noninterventional study conducted in nine European countries. Questionnaires were used to measure patient compliance and to assess patients’ and nurses’ experiences. All adverse events were recorded by severity, including injection site reactions or pain. Patient satisfaction and health-related quality of life were assessed using the Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9) and EuroQol-5 Dimension (EQ-5D) instruments, respectively. Results Of 582 patients enrolled, 568 (98%) received at least one injection and attended the first follow-up visit at 6 weeks, and 542 (93%) attended the second follow-up visit at 12 weeks. For the whole study, 548 of 568 (97%) patients were compliant with treatment. Among the various questions assessing whether the device was easy and quick to use accurately, without fear of the needle, 56%–98% of patients and 59%–98% of nurses were in agreement. There were nine serious adverse events (four disease-related) reported among the 227 (39%) patients reporting adverse events. Scores increased in the TSQM-9 convenience domain between weeks 6 and 12 (P=0.0009), and in the EQ-5D visual analog scale between baseline and week 12 (P<0.0001), indicating improvement in health-related quality of life. Conclusion ExtaviJect 30G was convenient to use and was associated with high levels of compliance.

Abstract
Lung cancer is recognized among the most frequent causes of paraneoplastic neurological syndromes (PNS). Neurological syndromes in subjects with systemic malignancy remain a clinical and diagnostic challenge. The aim of the study was to evaluate the frequency of NPS, their clinical manifestation and association with onconeural antibodies in patients with lung cancer. Fifty patients hospitalized with the diagnosis of PNS participated in the study. Neurological evaluation consisted of the Rankin scale (mRS), the Barthel index (BI), and testing for the presence of onconeural antibodies by means of indirect immunofluorescence, as screening, and Western blotting as confirmation. The majority of lung cancer patients (64%) aged 62 ± 10 had NPS symptoms. Their neurological condition and daily living activities were reasonable: mRS (1.0; 0.0-4.0) and BI (100; 7.4-100) scores. Classical PNS were found in 30% of cases and included sensory neuropathy (16%), paraneoplastic cerebellar degeneration (12%) as the most frequent symptoms. Autoimmune reaction was observed in 42% of lung cancer patients and in 20% was represented by well-characterized onconeural antibodies. Anti-Hu antibody was identified as the most frequent. In conclusion, PNS signs in lung cancer patients have both classical and non-classical features. In the course of SCLC only well-characterized onconeural antibodies were identified. The presence of well-characterized onconeural antibodies is strongly associated with classical features of PNS.

Abstract
Platelets participate in the development and progression of atherosclerosis. During this process they interact with endothelial cells and leukocytes. Therefore, we investigated the associations between carotid atherosclerosis and platelet reactivity markers. The platelet surface expression of P-selectin (CD62P) and the activated GPIIb/IIIa receptor (corresponding to increased binding of PAC-1), as well as the fraction of platelet-derived microparticles (PMPs) prior to and after platelet stimulation with TRAP or ADP, were determined using flow cytometry in 94 subjects in the convalescent phase of ischaemic stroke and in 76 disease controls. The mean common carotid intima-media thickness (CCA(mean) IMT), maximal common carotid IMT (CCA(max) IMT) and maximal bifurcation IMT (BIF(max) IMT) were measured bilaterally using B mode, colour Doppler ultrasonography. In stroke subjects IMT within CCA and BIF were greater than in disease controls and the percentage of PMPs prior to and after ex vivo stimulation with agonists was significantly higher than in controls. Multiple regression analysis revealed that PMPs were positively and independently correlated with both CCA(mean) IMT (β = 0.23; p < 0.01) and stroke (β = 0.21; p<0.01), while PAC-1 binding to platelets activated with ADP was negatively and independently associated with CCA(mean) IMT (β = -0.29; p<0.001) and atherosclerotic carotid plaque presence (β = -0.28, p = 0.003). We found a positive association between enhanced PMP formation and atherosclerotic thickening of carotid intima-media or carotid plaque in patients after ischaemic stroke. We demonstrated that diminished expression of active GPIIb/IIIa in the ADP-activated platelets is associated with increased carotid IMT, independently of stroke.

Abstract
The white blood cell count and mean platelet volume determined shortly after the symptom onset are known as independent predictors for clinical outcome after stroke. In the present study we sought to evaluate the prognostic value of platelet-derived inflammatory biomarkers measured prospectively after an ischaemic event. Using five-colour flow cytometry, the platelet surface expression of CD40L, CD62P and subpopulations of leukocyte-platelet aggregates were assessed in 93 stroke patients on the first (V(0)), 10th (V(1)) and 90th (V(2)) day after stroke, and once in 65 disease controls. The clinical outcome was evaluated using the Scandinavian Stroke Scale (SSS) and modified Rankin Scale (mRS) at the same time points as blood sampling and 24 months after the event. Patients with either CD40L surface expression or the percentage of monocyte-platelet aggregates (M-plt) in the third tertile (T3) at V0 had a significantly lower score on the SSS at V(1). Patients with the percentage M-plt at V(0) higher than the median value of M-plt in controls were at increased risk of SSS < 40 at V(1) (odds ratio: 2.6; 95% confidence interval [CI]: 1.4 - 8.7; p=0.006). Patients with the percentage of M-plt in T3 at V(0) showed progressive decline in survival (hazard ratio [HR]: 1.6; 95% CI: 1.1-1.9; p=0.02) and a significantly higher number of recurrent vascular events (HR: 2.64; 95% CI: 1.3-3.2; p=0.02) when compared to the first tertile. In conclusion, increased levels of M-plt could be a predictive marker for both early outcome and long-term prognosis while increased CD40L was correlated with worse clinical outcome.

Abstract
Environmental causes and genetic factors play important role in causation of multiple sclerosis (MS). Tobacco smoking is recognized as a risk factor of the most common inflammatory demyelinating disorder of central nervous system. Experimental studies showed inhibitory effect of tobacco smoke compounds on interferon production. The aim of this study was the evaluation of tobacco smoking on clinical effectiveness of immunomodulatory treatment of multiple sclerosis. Material and methods. The study included 79 multiple sclerosis patients treated with interferon beta for at least two years. MS was diagnosed basing on Mc Donald criteria. The study group included patients participating in reimbursed immunomodulatory treatment of MS. Disease duration, clinimetric evaluation based on EDSS, relapses rate before and during disease modifying therapy (DMT) were analyzed. Results. Current smokers constituted 19% of MS patients undergoing DMT with interferon beta. No differences in disease duration (3, 2 - 4 and 3, 2 - 4 years; median, interquartile range), EDSS score (1; 0,0 - 1,5 and 1; 0,0 -1,75) and relapse rate before DMT initiation (3; 2,0 - 3,5 and 3, 2,0- 4,0) respectively between smokers and non-smokers were found. Interferon beta treatment caused reduction in relapse rate both in non-smokers (before treatment: 2; 2-3, during DMT: 0; 0-0, median; interquartile range, P<0.0001), and smokers (before treatment : 2; 2-4, during DMT: 0; 0 - 0, P = 0.0001). In non-smoking MS patients the relapse rate during MDT correlated with disease duration (Kendall tau = 0.220; P=0.0270), but such a relationship was not observed in smokers with MS. In multiple regression analysis, in the model including the effect of disease duration, baseline EDSS score and smoking status on relapse rate during DMT tobacco smoking was found as the significant (p=0.0012) and independent factor (B = 0.4597).

Abstract
The expression of the most important chaperone protein - Hsp70 and autoimmunity directed against it is a risk factor of cardiovascular diseases, increased in subjects with alcohol use disorder (AUD). The aim of the study was to evaluate the level of anti-Hsp 70 protein antibodies (anti-Hsp 70) in sera of AUD patients during abstinence period. Material and methods. The study included 54 subjects with AUD diagnosed basing on DSM IV criteria. In the studied group clinimetric evaluation was performed, plasma lipids, basic transketolase activity in erythrocytes (TK), thiamine pyrophosphate (TPP) activation of transketolase and the level of anti-Hsp 70 antibodies were evaluated as well. Results. In AUD subjects anti-Hsp 70 level was decreased during abstinence period. During first month of abstinency it correlated negatively with total cholesterol concentration (rS=-0.8857, p=0.0188) and the percentage of TPP stimulation (rS=-0.5960, p<0.05), and during 6 months of abstinence with HDL cholesterol (rS=-0.6848, p=0.0289). After 1 year of abstinence anti-Hsp 70 correlated positively with basic TK activity (rS=0.9550, p=0.0008). Sex is an independent factor influencing anti-Hsp 70 level in AUD subjects (B=60.9469, p=0.0435). In multiple regression model including results of clinimetric evaluation and its effect on the level of anti-Hsp 70 antibodies in AUD patients during 1 month of abstinency anti-Hsp 70 correlated with TWEAK scale score (BETA=-1.4543, p=0.0144) and AUDIT score (BETA-=1.2255, p=0.0224). In 2-6 months of abstinency anti-Hsp 70 correlated with TWEAK score (BETA=1.1110, p=0.0418). After 1 year of abstinency anti-Hsp 70 correlated with AUDIT score (BETA=-1.2161, p=0.0210). Conclusion. The autoimmune reaction against Hsp 70 is decreased during abstinency in AUD patients. Its relation with plasma lipids and thiamine deficiency may lead to increased risk of cardiovascular disorders. TWEAK and AUDIT scoring seem to be most useful for clinimetric evaluation in the context of the role of anti-Hsp 70 antibodies.

Abstract
The overall objective of the Polish guidelines for the prevention and treatment of venous thromboembolism is to increase patient benefit and safety by appropriate prevention and treatment of deep vein thrombosis and pulmonary embolism as well as proper management of the complications associated with antithrombotic and thrombolytic therapy. These guidelines apply to adult trauma, cancer, surgical, and medical patients as well as those at increased risk of venous thromboembolism. Specific recommendations have been formulated for pregnant women, patients requiring surgery while receiving long-term oral anticoagulant treatment, and patients undergoing regional anesthesia and/or analgesia. We chose to update the existing Polish guidelines with the use of the most recent high-quality international guidelines that we identified and adjusted the final product to Polish cultural and organizational setting. We based our recommendations primarily on the 9th edition of the American College of Chest Physicians Evidence-Based Clinical Practice Guidelines on Antithrombotic Therapy and Prevention of Thrombosis, the European Society of Cardiology Guidelines on the Diagnosis and Management of Acute Pulmonary Embolism, the 3rd edition of the American Society of Regional Anesthesia and Pain Medicine Evidence-Based Guidelines on Regional Anesthesia in the Patient Receiving Antithrombotic or Thrombolytic Therapy, the ACOG practice bulletin on thromboembolism in pregnancy (Number 123), and Guidance from the Scientific and Standardisation Committee of the International Society on Thrombosis and Haemostasis on the Duration of Anticoagulant Therapy after a First Episode of Unprovoked Pulmonary Embolus or Deep Vein Thrombosis, as well as two other Polish practice guidelines on the prophylaxis and treatment of venous thromboembolism and the management of patients treated with oral direct inhibitors of factor X or factor II. To make recommendations regarding specific management issues that had not been addressed in other guidelines, or whenever the panel members felt they needed additional information to reach the decision, we also consulted the authors of guidelines developed by other professional societies and organizations as well as additional sources of evidence. For each adapted recommendation, we explicitly assessed its relevance and applicability in the context of the healthcare system in Poland. When necessary, we explicitly stated the rationale for modification of the previously published recommendations and judgements about the values and preferences we assumed. The information regarding reimbursement of drugs mentioned in the recommendations was added in chapters 6-9 and 13 and approved by the National Health Fund. The final version of the practice guidelines was officially approved by the scientific societies and institutions listed at the beginning of the document.

Abstract
Although the platelet activation profile after stroke is a well-known issue, the platelet reactivity assessed prospectively after ischaemic stroke still remains equivocal. The aim of this study was to evaluate the reactivity of platelets in response to stimulation with thrombin receptor-activating peptide (TRAP) at 1, 10 and 90 days after ischaemic stroke and to compare it with results obtained in control groups. We determined the increment in surface expression of CD62P, CD40L and monocyte- and granulocyte-platelet aggregate formation using five-colour flow cytometry in 86 subjects after an ischaemic event, in 62 disease controls, and in 38 healthy volunteers. We assessed the plasma levels of CD62P and CD40L soluble forms. In patients after stroke a significantly lower increment in CD62P surface expression (p < 0.01) and higher increments in both CD40L platelet surface expression (p < 0.01) and monocyte-platelet aggregate percentage (p < 0.01) were found at every studied time point, as compared with the control groups. Plasma levels of soluble CD62P (sCD62P) and soluble CD40L (sCD40L) were increased in stroke subjects in both the acute and the subacute phase of the stroke and they dropped to levels observed in controls at day 90 after the ischaemic incident. In all studied groups a positive correlation was noted between plasma levels of sCD62P and sCD40L. In conclusion, while at 3-month follow-up the levels of soluble forms normalize in stroke patients, the profile of platelet reactivity in response to activation with TRAP differs from that observed in the controls despite the secondary stroke prevention.

Abstract
Vascular and degenerative diseases of the central nervous system are one of the most common health problems in the elderly. Cognitive dysfunction, mood disorders and behavioural changes as well as psychotic symptoms constitute an invariable part of the clinical manifestation of these diseases. Psychopathological syndromes influence management decisions, commonly being a reason for patients' institutionalization; they are also a cause of suffering of patients and their caregivers and relatives. Relevant diagnosis of psychological symptoms is crucial in establishing adequate therapy, which improves quality of life of patients and their caregivers. The paper provides an overview of the psychopathological presentation of the most common central nervous system diseases in the elderly.

Abstract
The aim of the study was to determine the extent of oxidative DNA damage (levels of 8-oxo2dG) and expression of OGG1 and p53 and TNF-α proteins in lymphocytes of Alzheimer's disease (AD) patients and a control group. The studies were conducted on 41 patients with AD, including 25 women and 16 men aged 34-84 years. The control group included 51 individuals, 20 women and 31 men aged 22-83 years. The level of 8-oxo2dG was determined using HPLC/EC/UV, and the level of OGG1 and p53 and TNF-α proteins was determined with the Western blot method. The results showed that both proteins participating in DNA repair (OGG1, p53) and the inflammatory protein TNF-α are involved in pathogenesis of neurodegenerative diseases. It also seems that a specific system for DNA repair (OGG1) may contribute to downregulation of the inflammatory factor (TNF-α) level, especially in the early stages of dementia. Moreover, the results showed that p53 protein can fulfil its function in DNA damage repair only in early stages of dementia. It is possible that OGG1 and p53 and TNF-α proteins together or separately may be involved in pathogenesis of AD by repair of oxidative DNA damage and/or apoptosis.

Abstract
Background: Patient-reported quality of life (QOL) is an outcome measure in clinical trials in multiple sclerosis (MS), but translated QOL instruments may affect the actual comparability of data. Objectives: We aimed to investigate possible differences in QOL in MS between cultures and countries. We employed the Functional Assessment of Multiple Sclerosis (FAMS) Version 4 questionnaire, which is a state-of-the-art QOL instrument. Methods: Some 484 MS patients from Austria (145), Germany (144), and Poland (195) aged 20–60 years, and stratified for sex and disease severity as measured by the Expanded Disability Status Scale (EDSS) score completed the respective FAMS translation and a socio-demographic questionnaire. Results: Analysis of variance and post-hoc Scheffé-test showed that 64% of the FAMS items were answered significantly differently ( p < 0.001) between the three countries. A multivariate regression analysis including all the available disease-related and socio-demographic variables revealed the factors age, EDSS score, employment, social contacts, MS course, and country to be significant predictors of both the total FAMS score and the score for items answered differently between the three countries. Conclusions: Differences exist in the QOL of MS patients from Austria, Germany, and Poland which seem to lie beyond the impact of disease severity. They appear to be related to culture or other country-specific factors, as country was an independent predictor of differently answered items of the FAMS and thus also of the whole FAMS. QOL instruments should consider this aspect to faithfully reflect subjective information such as patient-reported benefit of treatment in multinational clinical trials.
