AIM: To assess the safety and efficacy of mechanical thrombectomy (MT) with stent-retrievers in anterior circulation stroke (ACS) patients due to the occlusion of major cerebral arteries, and to compare the results achieved in patients on oral anticoagulation (OAC) and those not on OAC. MATERIALS AND METHODS: The present retrospective study comprised 285 consecutive patients (115 males; mean age 74±13 years). The following data were collected: baseline characteristics, occurrence of risk factors, pre-event treatment with OAC, neurological deficit at the time of treatment, time to therapy, recanalisation rate (successful recanalisation defined as Thrombolysis in Cerebral Infarction score ≥2b), post-treatment imaging findings. The 90-day clinical outcome was assessed using modified Rankin scale (good outcome defined as 0-2). RESULTS: The following statistically insignificant differences were found in 26 patients on OAC versus 259 patients without OAC: occurrence of symptomatic intracerebral haemorrhage 7.7% versus 8.1%, achievement of successful recanalisation 69.2% versus 82.6%, good 90-day clinical outcome 34.6% versus 56.8%, 90-day mortality 26.9% versus 20.8% (p>0.05 in all cases). Age and neurological deficit at the time of treatment were identified as independent negative predictors of good 90-day clinical outcome (odds ratio [OR]=0.90, 95% confidence interval [CI]: 0.88-0.94 and OR=0.83, 95% CI: 0.77-0.90, respectively) and as independent positive predictors of mortality (OR=1.12, 95% CI: 1.06-1.18 and, OR=1.17, 95% CI: 1.07-1.27, respectively; p<0.05 in all cases). CONCLUSIONS: MT with stent-retrievers is safe and effective in ACS patients on OAC.

BACKGROUND: Proper management of multiple sclerosis (MS) requires feedback from clinical practice via registries. OBJECTIVE: To introduce the Czech national multiple sclerosis registry, ReMuS, and explore the availability and use of disease-modifying drugs (DMD). METHODS: The analysis focused on patients who started their first DMD, either with first-line or second-line medication and was based on reimbursement criteria set by Czech regulators. Baseline information was used to predict relapses after DMD initiation and to compare patients that started DMD in different years. RESULTS: A total of 3,328 patients started DMD treatment for MS between 2013 and 2016; 3,203 on first-line and 125 on second-line medication. The proportion of patients starting on second-line drugs increased from 1.8% in 2013 to 4.7% in 2016. The occurrence of a relapse within one year of DMD initiation was significantly related to (1) the Expanded Disability Status Scale (EDSS) score immediately prior to starting DMD and (2) the number of previous relapses. Both parameters were significantly lower in patients starting in later years of the explored interval. CONCLUSION: Data from the ReMuS registry highlights improvements made in the management of MS in the Czech Republic. However, a relatively low percentage of patients started treatment using second-line drugs, in contrast to trends in other countries.

Background and Objective. Needle electromyography can be used to detect the number of changes and morphological changes in motor unit potentials of patients with axonal neuropathy. General mathematical methods of pattern recognition and signal analysis were applied to recognize neuropathic changes. This study validates the possibility of extending and refining turns-amplitude analysis using permutation entropy and signal energy. Methods. In this study, we examined needle electromyography in 40 neuropathic individuals and 40 controls. The number of turns, amplitude between turns, signal energy, and "permutation entropy" were used as features for support vector machine classification. Results. The obtained results proved the superior classification performance of the combinations of all of the above-mentioned features compared to the combinations of fewer features. The lowest accuracy from the tested combinations of features had peak-ratio analysis. Conclusion. Using the combination of permutation entropy with signal energy, number of turns and mean amplitude in SVM classification can be used to refine the diagnosis of polyneuropathies examined by needle electromyography.

BACKGROUND: Drug development for Alzheimer disease (AD) is challenged by the success in animal models tested in the Morris water maze (MWM) and the subsequent failures to meet primary outcome measures in phase II or III clinical trials in patients. The human variant of MWM (hMWM) enables us to examine allocentric and egocentric navigation as in the MWM. OBJECTIVE: It was the aim of this study to examine the utility of a computerized hMWM to assess the effects of donepezil in mild AD. METHODS: Donepezil 5 mg/day was started after initial hMWM testing in the treated group (n = 12), and after 28 days, the dose was increased to 10 mg/day. The performance after 3 months was compared to that of a non-treated group (n = 12). RESULTS: Donepezil stabilized or improved the spatial navigation performance after 3 months, especially in the allocentric delayed recall subtask (p = 0.014). CONCLUSIONS: The computerized hMWM has the potential to measure the effects of donepezil in mild AD. It is a sensitive cognitive outcome measure in AD clinical trials.

BACKGROUND: Studies have shown slow healing of peripheral nerve injury in elderly patients. Carpal tunnel syndrome (CTS) is the most frequent compressive mononeuropathy, affecting mostly older people and females. Few studies have assessed electrophysiological differences between younger and older patients. We aimed to evaluate age-dependent differences in electrophysiological parameters preoperatively and postoperatively over a 100-day postoperative period. METHOD: This retrospective study included 258 hands of patients who underwent conventional open-technique carpal tunnel syndrome surgery. Patients with paresthesia in the median nerve distribution or with impaired sensation or abnormal findings in sensory and motor median nerve conduction studies were enrolled. The age dependence of the preoperative values of distal motor latency, amplitude of the compound motor action potential and sensory conduction velocity was estimated using regression analysis. RESULTS: Statistically significant age dependence was found for the preoperative distal motor latency, compound motor action potential, amplitude and sensory conduction velocity. The repair of segmental demyelination was nearly twice as slow in the older group, at a 5 % significance level, even when comparing groups with the same preoperative distal motor latency. CONCLUSIONS: Analysis of preoperative nerve conduction parameters indicates that surgery for carpal tunnel syndrome is performed later in older patients.
