Based on density functional theory results, an experimental screening of 10 distinct DESs for chitin deacetylation followed. The most promising DESs were identified as K2CO3glycerol (K2CO3G), choline chlorideacetic acid ([Ch]ClAA), and choline chloridemalic acid ([Ch]ClMA) and were subjected to further optimization with respect to the water content, process duration, and temperature. Ultimately, [Ch]ClMA showed the best results, yielding a degree of deacetylation (DDA) of 40% after 24 h of reaction at 120 °C, which falls slightly behind the threshold value (50%) for chitin to be considered chitosan. Further quantum chemical calculations were performed to elucidate the mechanism. Upon the removal of 40% N-acetyl groups from the chitin structure, its reactivity was considerably improved.The COVID-19 pandemic is the largest global public health outbreak in the 21st century so far. Based on World Health Organization reports, the main source of SARS-CoV-2 infection is transmission of droplets released when an infected person coughs, sneezes, or exhales. Viral particles can remain in the air and on the surfaces for a long time. These droplets are too heavy to float in air and rapidly fall down onto the surfaces. To minimize the risk of the infection, entire surrounding environment should be disinfected or neutralized regularly. Development of the antiviral coating for the surface of objects that are frequently used by the public could be a practical route to prevent the spread of the viral particles and inactivation of the transmission of the viruses. In this short review, the design of the antiviral coating to combat the spread of different viruses has been discussed and the technological attempts for minimizing the coronavirus outbreak have been highlighted.Neurologists around the country and the world are rapidly transitioning from traditional in-person visits to remote neurologic care because of the coronavirus disease 2019 pandemic. Given calls and mandates for social distancing, most clinics have shuttered or are only conducting urgent and emergent visits. As a result, many neurologists are turning to teleneurology with real-time remote video-based visits with patients to provide ongoing care. Although telemedicine utilization and comfort has grown for many acute and ambulatory neurologic conditions in the past decade, remote visits and workflows remain foreign to many patients and neurologists. Here, we provide a practical framework for clinicians to orient themselves to the remote neurologic assessment, offering suggestions for clinician and patient preparation before the visit; recommendations to manage common challenges with remote neurologic care; modifications to the neurologic examination for remote performance, including subspecialty-specific considerations for a variety of neurologic conditions; and a discussion of the key limitations of remote visits. These recommendations are intended to serve as a guide for immediate implementation as neurologists transition to remote care. These will be relevant not only for practice today but also for the likely sustained expansion of teleneurology following the pandemic.Individuals with intellectual and developmental disabilities (IDDs) are among our most medically vulnerable neurologic patient population. As such, they are at particular risk of psychosocial and medical harm during the coronavirus disease 2019 (COVID-19) pandemic. Here, we highlight strategies to decrease potential infectious exposures and ensure continued optimal neurologic care for individuals with IDD during the COVID-19 pandemic. Finally, in a climate of potential medical resource restriction, we offer some suggestions for advocacy on behalf of individuals with IDD.New-onset refractory status epilepticus (NORSE) is rare condition, and sharing knowledge is vital in its management, based on strict collaboration between multiple specialists, continuous EEG (c-EEG) monitoring, and prompt therapy modification. The coronavirus disease 2019 (COVID-19) pandemic challenged many of these established practices because of “social distancing” measures, making it necessary to work around physical restrictions. We report a case of a 10-year-old with NORSE admitted in a pediatric intensive-care unit and monitored with c-EEG and amplitude-integrated EEG. The monitoring interface was livestreamed using videoconference web-based platforms allowing remote viewing. Multiple daily web meetings took place between team members, where real-time therapy response was evaluated and confronted with medium-term trends in the epileptic activity, dictating further treatment and diagnostic steps. In addition to the known use of telemedicine in chronic conditions, we report how its use can be exploited to treat urgent conditions such as NORSE. By taking advantage of new tools and virtual environments, we were able to share treatment and diagnostic decisions and guarantee real-time therapy adjustments and a coherent course in treatment despite restrictions necessary for the COVID-19 pandemic. read more The constant specialist monitoring and the coherent and on-time communication of the patient’s condition relieved the family stress, usually complained in these situations.We describe the University of Toronto Adult Neurology Residency Program’s early experiences with and response to the coronavirus disease 2019 pandemic, including modifications to the provision of neurologic care while upholding neurology education and safety. All academic and many patient-related activities were virtualized. This maintained physical distancing while creating a city-wide videoconference-based teaching curriculum, expanding the learning opportunities to trainees at all academic sites. Furthermore, we propose a novel split-team model to promote resident safety through physical distancing of teams and to establish a capacity to rapidly adapt to redeployment, service needs, and trainee illness. Finally, we developed a unique protected code stroke framework to safeguard staff and trainees during hyperacute stroke assessments in this pandemic. Our shared experiences highlight considerations for contingency planning, maintenance of education, sustainability of team members, and promotion of safe neurologic care.
