It’s mid-January and the end of another week of the new year, 2021. Hopefully, you have had a relaxing holiday and a smooth start to the year. Grab a coffee/tea/beer/wine and end the mid-January week with a quick recap of Sleep Science News!
The new year brings us positive news and optimistic expectations that the global pandemic will end and life will slowly come back to normalcy.
Despite the bad news coming in during the first days of 2021, including one about new variants of the coronavirus that has put some countries (like the UK) into a strict lockdown and long night curfews, vaccine distribution gives hope that the isolation should end in the coming year. Mass vaccinations have recently started, with the UK being the first country worldwide to administer the vaccine to people on 8 December 2020. So the first individuals to receive the vaccine have already gotten 2 shots which is essential for developing immunity. The numbers are continuously increasing (https://ourworldindata.org/covid-vaccinations). In early 2021, Israel announced the highest vaccination rate (22 per 100 people) getting to the top of the list beating the UK (4.5 per 100) and USA (2.8 per 100) followed by Italy and Germany (≈1 per 100) and other countries.
In addition, treatments evolved in 2020 (the use of steroids, approval of the antiviral drug Remdesivir [Beigel JH et al., 2020 https://www.nejm.org/doi/full/10.1056/NEJMoa2007764 ], at least in a selected group of patients at high risk of inflammatory response [Young B et al., 2020, https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(20)30911-7/fulltext], and the emergency use authorization of monoclonal antibodies https://www.fda.gov/news-events/press-announcements/coronavirus-covid-19-update-fda-authorizes-monoclonal-antibody-treatment-covid-19 ) also provide promising results. However, the continued search for other effective therapeutic approaches is essential.
With regard to the sleep field, we are encountering new issues. An increase in rates of sleep disorders (insomnia symptoms, nightmares, decreased sleep quality, changes in sleep-wake patterns, REM sleep behaviour disorder and others) during pandemic has been previously reported [Partinen M. Sleep research in 2020: COVID-19-related sleep disorders. Lancet Neurol. 2021 Jan;20(1):15-17. doi: 10.1016/S1474-4422(20)30456-7]. In the beginning, it was mainly associated with stress, anxiety and changed schedules during lockdown. However, as the data are accumulating it seems that patients affected by SARS-CoV-2 are at higher rate of developing sleep disorders which might be related to viral or drug effects. The sleep-related medical community are now facing many questions: Do we need to re-evaluate the epidemiology of sleep disorders and re-assess the prevalence of insomnia? Should COVID-19 be listed among the potential causes for certain sleep disorders? How does sleep change vaccination efficiency and immunization against SARS-CoV-2? What impact do vaccines have on sleep and sleep-related symptoms etc.?
Our guest today, Professor Florin Dumitru Mihaltan, Professor, Head of Pneumology Department at the University of Medicine and Pharmacy “Carol Davila” in Bucharest (Romania) and the President of the Romanian Somnology Section of the Pneumology Society, shares with us recent news from Romania and the challenges and difficulties that sleep clinics are experiencing during the pandemic.
The Romanian Somnology Section has kept traditional meetings and events in online format in 2020, including the “Sommer school of Somnology”, joint webinar with the “Groupe du Sommeil”, and the 6th Romanian Pediatric Sleep Conference proving that the pandemic cannot stop medical meetings and knowledge exchange. He also gives us an overview of the development and promotion of somnology in Romania which due to the efforts of Professor Mihaltan and his team was recognized as a competency area over 10 years ago.
We thank Professor Mihaltan for sharing your experience with us.
Happy New Year and a good start for new education, scientific, clinical and other experiences in 2021!
Have a great weekend everyone!
