Abstract:
Falls and fall-related injuries remain a frequent complication of strokes. Fall and injury prevention based on fall risk scores and level of fall risk, such as low, moderate or high, is insufficient, requiring that clinicians redesign fall prevention programs based on patient’s individualized fall and injury risk factors. Accepting that stroke is one of the leading causes of disability world-wide, all efforts should be made to protect these patients from falls and fall-related injuries. It is well known that falls result in fear of falling, greater disability and even loss of life. While the evidence for stroke-specific fall prevention interventions is still emerging, clinical experts must rely on clinical expert knowledge to conduct stroke-specific fall risk assessment needed to individualize fall prevention plans of care, while assuring injury risk and prevention strategies are included. This population-based approach presented in this lecture redesigns traditional universal programs in order to enhance infrastructure and capacity to individualized fall and injury risk factors and history, and protection from injury should a fall occur. Increased attention is essential to protect stroke patients from fall-related injuries. Clinical expertise is essential for safe practices for these patients. Equipment use specifically designed to reduce trauma during a fall, such as hip protectors and floor mats, must be reliably integrated into patient care. Even though acute care units have diverse patients, known fall and injury risk factors specific to type and severity of stroke must be implemented and tested for effectiveness.

Abstract:
Sleep medicine lags behind other medical disciplines because of the complexity in neurosciences, especially in discrete brain areas related to sleep-wake mechanisms. With the advancement of biotechnology and neurobiology, new ideas have emerged in sleep medicine. For example, new imaging technique has found out that the brain GABA level was reduced in un-medicated primary insomniacs. Sleep-wake cycle disturbances may be used for early diagnosis of neurocognitive disorders with aberrant tau protein, as it was found to be a cause for the damage of neurons in patients with neurocognitive disorders leading to sleep disturbance which may be used to pathological fibrillation of alpha-synuclein protein, leading to the formation of Lewy bodies, could be prevented by monoclonal antibodies against Epstein-Barr virus, or a rosmarinic acid or cuminaldehyde. The possible biomarker of rapid-eyemovement sleep behaviour disorder (RSBD) may help in earlier diagnosis and treatment for Parkinson’s disease. This point towards a direction for future treatment of alpha-synucleinopathies including Parkinson’s Disease and their sleep problems. The central pathology may give a new direction of management for patients with Alzheimer’s disease or others with tauopathy.

Natallia Halinouskaya
Gomel State Medical University, Belarus
Title: Status of autonomic nervous system in patients with transient ischemic attack and stroke
Time : 12:00-12:30
Biography:
Natallia Halinouskaya has completed her PhD at the National Academy of Sciences of Belarus and Postdoctoral studies at Gomel State Medical University and National Science and Practice Centre of Medical Assessment and Rehabilitation. She is the Dean of the Postgraduate Faculty at Gomel State Medical University, the Coordinator of the Educational Program Today and Tomorrow for stroke patients and patients with stroke risk factors. She has published more than 150 papers in reputed journals and has been serving as an Editorial Board Member of reputed journals.
Abstract:
Aim: This study purpose was to determine the autonomic nervous system (ANS) parameters that may differ the pathogenesis of transient ischemic attack (TIA) from stroke. Methodology: A prospective cohort study was conducted in the Department of Neurology and Neurosurgery at the Gomel State Medical University, Stroke Unit of the Gomel Regional Veterans Hospital, between May 2014 and March 2016 which includes 97 patients: TIA group - 13 patients and 84 stroke patients: 61 having size of stroke lower than 15 mm (lacunar stroke – LS), 23 having size of stroke greater than 15 mm (total stroke – TS). Heart rate variability (HRV) was used to describe status of the ANS. It was measured at 1st and 10th day after admission. Obtained HRV records were analyzed using the following four parameters: SDNN (standard deviation of the normal-to-normal R-R intervals, in ms), ΔX (the difference between maximal and minimal R-R interval, in ms), Mo (mode of the duration of R-R intervals, in ms), AMo (amplitude of the R-R intervals mode, in percent). Results: For the HRV taken on the 1st day, the dependence between ΔX (representing activity of parasympathetic part of ANS) and Mo (representing sympathetic part of ANS) was found to be significantly different for TIA and TS groups (p=0.016). Conclusion: The key difference between TIA and TS is a difference in the relationship between the humoral regulation of the activities of the ANS and the parasympathetic part activity at 1st day, which determines specific features of pathogenesis of the transient ischemia.

Title: Telomerase activators improve motor function and protein degradation in a mouse model of Parkinson′s disease
Time : 12:30-13:00
Biography:
Gabriele Saretzki has completed her PhD at Humboldt University, Berlin and performed most of her Postdoctoral studies at the Institute for Ageing and Health in Newcastle upon Tyne (UK) where she is a Lecturer in Ageing Research since 2002. Her main research interests include “Telomeres, telomerase, senescence, ageing, oxidative stress and mitochondria”. She has pioneered work on non-canonical functions of the telomerase protein TERT shifting her focus recently to brain ageing and neurodegenerative diseases. She has published more than 84 papers in peer-reviewed journals and is an Editorial Board Member of BMC Biology, PLOS One and Oxidative Medicine and Cellular longevity.
Abstract:
While telomerase maintains telomeres in dividing cells, its protein component TERT (telomerase reverse transcriptase) has various non-canonical functions such as localisation to mitochondria resulting in decreased oxidative stress, apoptosis and DNA damage. TERT protein persist in adult neurons while telomerase activity is downregulated early during development. We recently demonstrated increased mitochondrial TERT protein in hippocampal neurons from Alzheimer’s disease brains and mutual exclusion of pathological tau and TERT. Transduction of mutated tau into cultivated neurons confirmed that TERT decreases mitochondrial oxidative stress and lipid oxidation. Mitochondrial dysfunction is also involved in the development of other neurodegenerative diseases. Treatment of Parkinson’s disease (PD) model mice overexpressing human wild-type alpha-synuclein with 2 telomerase activators resulted in increased TERT expression in brain and amelioration of PD symptoms by significantly improving balance, gait and motor function as well as mitochondrial function. Analysing levels of total and phosphorylated alpha-synuclein we found a substantial decrease of both proteins in the hippocampus and neocortex suggesting a better protein degradation after telomerase activator treatment. Interaction of TERT with proteasomal and autophagy pathways has been described recently. Accordingly, we found a decrease in poly-ubiquitinated proteins and the autophagy receptor p62 and analyse the involvement of these degradation pathways currently. We also present data on DNA damage, telomere-associated foci (TAFs), BDNF, MnSOD, mitochondrial proteins and aggregated alpha synuclein in different brain regions. Thus, our results suggest that telomerase activators might form novel treatment options for better degradation of toxic proteins in neurodegenerative diseases such as PD and AD.

Title: Pre and postoperative fatigue in patients undergoing neurovascular surgery
Time : 14:40-15:10
Biography:
Kiti Muller is a Neurologist with a PhD in Neuroimmunology. She is the Senior Neuroscientist at Nokia Bell Labs; Adjunct Professor in Neurology at Helsinki University and; in Cognitive Neuro-ergonomics at Aalto University, School of Science. Her research in Cognitive Neurophysiology focuses on sleep, fatigue and vigilance in different medical conditions and their effects on working ability of patients.
Abstract:
Patients recovering from surgery frequently experience symptoms of fatigue. Objective measures of fatigue could be used to follow recovery progress, optimize daily activities to patient’s resources and evaluate working ability. Increased eye closure time per minute (ECT/min) has been used as an indicator of decreased alertness. We used ECT/min to study fatigue of patients undergoing elective neurosurgical treatment for unruptured intracranial aneurysm. We recorded electro-oculography (EOG) from eight patients (40 yrs., SD 12, 3 male) before (9 am) and after (10:30 am) performing demanding computer tasks simulating knowledge work. During the 6.5 min EOG measurements patients watched a muted video film. The ECT/min values were individually baseline corrected to the mean of the first measurement. Measurements were done 1-22 days before and 1530 days after surgery. All patients were full-time employed with no history of stroke, mental disturbances, and intracranial procedures. In both, pre- and postoperative measurements the ECT/min values were higher after the cognitively demanding tasks (preop: W=774, p=0.008; postop: W=684, p=0.0008), suggesting decreased alertness and/or increased fatigue after tasks. Interestingly no difference was found between pre and postoperative measurements (W=1136, ns.), indicating that fatigue was not significantly greater after surgery. The ECT/min is a promising objective measure to evaluate and follow changes in fatigue and alertness of patients. Longer postoperative follow-up with larger patient groups are needed to study further development of task-related ECT/min values after neurosurgery and can the effect of task on ECT/min predict working ability.
