Acute polyneuropathy: a serious complication of levodopa/ /carbidopa intestinal gel treatment for Parkinson's Disease.

Aim Of Study: To determine whether a high dose of levodopa-carbidopa intestinal gel (LCIG), expressed as levodopa equivalent daily dose (LE daily dose), is a risk factor for acute polyneuropathy in patients treated with LCIG.

Clinical Rationale For Study: Treatment with LCIG is an effective device-assisted therapy in the advanced stages of Parkinson's Disease (PD). Polyneuropathy is a well-known complication of PD treatment.

Identification of alemtuzumab-suitable multiple sclerosis patients in Slovakia and sequencing of post-alemtuzumab immunomodulatory treatment.

Background: Alemtuzumab (ALEM) is a humanised monoclonal antibody that depletes circulating lymphocytes by selectively targeting CD52, which is expressed in high levels on T- and B-lymphocytes. This depletion is followed by lymphocyte repopulation and a cytokine expression shift towards a lesser inflammatory profile, both of which may contribute to prolonged efficacy. National recommendations for enrolling and treating multiple sclerosis (MS) patients with ALEM have been established.

Forecasting extremely high ischemic stroke incidence using meteorological time serie.

Motivation: The association between weather conditions and stroke incidence has been a subject of interest for several years, yet the findings from various studies remain inconsistent. Additionally, predictive modelling in this context has been infrequent. This study explores the relationship of extremely high ischaemic stroke incidence and meteorological factors within the Slovak population.

Disturbances in Muscle Energy Metabolism in Patients with Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS) is a fatal neuromuscular disease type of motor neuron disorder characterized by degeneration of the upper and lower motor neurons resulting in dysfunction of the somatic muscles of the body. The ALS condition is manifested in progressive skeletal muscle atrophy and spasticity. It leads to death, mostly due to respiratory failure.

Dyskinesia and Pain in Advanced Parkinson's Disease: Post Hoc Analysis from the Phase 3b, Open-Label, Randomized DYSCOVER Study.

Introduction: The DYSCOVER study was a phase 3b, open-label, randomized trial (NCT02799381) that evaluated levodopa-carbidopa intestinal gel (LCIG) versus optimized medical treatment (OMT) in patients with Parkinson's disease (PD) and a high burden of dyskinesia at baseline (defined as Unified Dyskinesia Rating Scale [UDysRS] total score ≥ 30). At week 12, patients receiving LCIG versus OMT experienced significant improvements in dyskinesia, pain, and health-related outcomes. The objective of this analysis was to examine correlations between dyskinesia, pain, and health-related outcomes in PD.

Endovascular thrombectomy for acute ischaemic stroke with established large infarct: multicentre, open-label, randomised trial.

Background: Recent evidence suggests a beneficial effect of endovascular thrombectomy in acute ischaemic stroke with large infarct; however, previous trials have relied on multimodal brain imaging, whereas non-contrast CT is mostly used in clinical practice.

Methods: In a prospective multicentre, open-label, randomised trial, patients with acute ischaemic stroke due to large vessel occlusion in the anterior circulation and a large established infarct indicated by an Alberta Stroke Program Early Computed Tomographic Score (ASPECTS) of 3-5 were randomly assigned using a central, web-based system (using a 1:1 ratio) to receive either endovascular thrombectomy with medical treatment or medical treatment (ie, standard of care) alone up to 12 h from stroke onset. The study was conducted in 40 hospitals in Europe and one site in Canada.

Derived iPS cells are capable to differentiate in vitro into three germ layers as verified by immunocytochemistry.

Analysis of Cdx2 VDR gene polymorphism rs11568820 in association with multiple sclerosis in Slovaks.

Vitamin D deficiency is involved in the pathogenesis of multiple sclerosis (MS), a severe autoimmune demyelinating disease of the central nervous system. The gene polymorphism Cdx-2 (rs11568820, G/A) seriously influences the trancriptional activity of the vitamin D receptor (VDR) that binds the vitamin D responsive elements of target genes including HLA-DRB1*15. The aim of the present study in Slovaks was to analyse the association of Cdx-2 variants with the risk of MS and disability progression, and to assess the DRB1*15:01 allele as a possible confounding factor.

Biomedical research brings mTBI biomarkers a step closer to the bedside - implementation in clinical practice.

Research in the field of TBI (traumatic brain injury) has long been focused on severe brain injury, while the number of mild injuries far overweigh severe injuries. Mild head injuries constitute up to 95% of all traumatic head injuries. The purpose of this work is to identify mTBI (mild traumatic brain injury) patients who are unlikely to benefit from CT (computed tomography) scanning.

Safety and efficacy of simple training protocol in patients after mild traumatic brain injury.

Aims: Mild Traumatic Brain Injury (mTBI) is the most common type of craniocerebral injury. Proper management appears to be a key factor in preventing post-concussion syndrome. The aim of this prospective study was to evaluate the effect and safety of selected training protocol in patients after mTBI.

Embolization of Ruptured Infratentorial Pial AVM in Pregnancy.

A primigravida 22-year-old woman, at a gestation of 23 weeks, experienced bleeding from a pial arteriovenous malformation (AVM) located in the right cerebellum. After interdisciplinary consensus and with the informed consent of the patient and her family, AVM embolization was performed. Complete occlusion of the AVM was achieved by embolization with PHIL (precipitating hydrophobic injectable liquid).

A high-throughput liquid chromatography-tandem mass spectrometry method for simultaneous determination of direct oral anticoagulants in human plasma.

Direct oral anticoagulants are widely used in many indications to prevent thromboembolic events. Routine therapeutic monitoring is not required; however, there is increasing evidence suggesting the benefit of plasma level measurement in some situations. In addition, laboratory monitoring might help improve patient and drug non-compliance and thus individualize therapy.

Imaging Methods Applicable in the Diagnostics of Alzheimer's Disease, Considering the Involvement of Insulin Resistance.

Alzheimer's disease (AD) is an incurable neurodegenerative disease and the most frequently diagnosed type of dementia, characterized by (1) perturbed cerebral perfusion, vasculature, and cortical metabolism; (2) induced proinflammatory processes; and (3) the aggregation of amyloid beta and hyperphosphorylated Tau proteins. Subclinical AD changes are commonly detectable by using radiological and nuclear neuroimaging methods such as magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), and single-photon emission computed tomography (SPECT). Furthermore, other valuable modalities exist (in particular, structural volumetric, diffusion, perfusion, functional, and metabolic magnetic resonance methods) that can advance the diagnostic algorithm of AD and our understanding of its pathogenesis.
