摘要： Background and purpose: The COVID-19 (SARS-CoV-2) outbreak has disrupted residency programmes due to university and hospitals' priorities to face this emergency at all cost. Most research projects and clinical trials were temporarily stopped or postponed. The Resident and Research Fellow Section (RRFS) of the European Academy of Neurology (EAN) has decided to assess the impact of the COVID-19 pandemic on neurology training. Methods: All EAN RRFS members were invited to fill out an online questionnaire of 40 items concerning their clinical involvement during the COVID-19 emergency, and the impact of the pandemic on their training (Appendix S1). Results: Of the 227 RRFS members who completed the questionnaire, 222 were from Europe, and of those 111 were from Portugal, Italy or France. Responders highlighted that severe restrictions have been imposed to face this pandemic, including reduction of inpatient beds, prohibition of in-person visits and limitation to hospital access for patients' relatives. This was accompanied by an increase in email correspondence and phone calls with 50% of countries allowing telemedicine to reach outpatients. Seventy-nine per cent of the respondents felt that the pandemic will probably have a serious impact on their training and career. Conclusion: The pandemic led to a disruption of neurology activities, including medical training and research. The long-run impact of these changes remains unknown, but it will probably change the way neurology practice and training will be organized for future generations.

摘要： Adequate food intake and relative abundance of dietary nutrients have undisputed effects on the brain function. There is now substantial evidence that dietary nutrition aids in the prevention and remediation of neurologic symptoms in diverse pathological conditions. The newly described influences of dietary factors on the alterations of mitochondrial dysfunction, epigenetic modification and neuroinflammation are important mechanisms that are responsible for the action of nutrients on the brain health. In this review, we discuss the state of evidence supporting that distinct dietary interventions including dietary supplement and dietary restriction have the ability to tackle neurological disorders using Alzheimer's disease, Parkinson's disease, stroke, epilepsy, traumatic brain injury, amyotrophic lateral sclerosis, Huntington's disease and multiple sclerosis as examples. Additionally, it is also highlighting that diverse potential mechanisms such as metabolic control, epigenetic modification, neuroinflammation and gut-brain axis are of utmost importance for nutrient supply to the risk of neurologic condition and therapeutic response. Finally, we also highlight the novel concept that dietary nutrient intervention reshapes metabolism-epigenetics-immunity cycle to remediate brain dysfunction. Targeting metabolismepigenetics-immunity network will delineate a new blueprint for combating neurological weaknesses. (c) 2021 Elsevier Inc. All rights reserved.
