Children with Coronavirus disease 2019 (COVID-19) are being reported to have manifestations of hyperinflammatory states and/or Kawasaki-like disease. In this study, we investigated children with typical and atypical Kawasaki disease (KD) likely to be associated with COVID-19. We have reported four children with Kawasaki-like disease probably associated with COVID-19. The clinical features were consistent with incomplete KD in three patients. SARS-CoV-2 RT-PCR was positive in one and the serology was positive in one patient with negative RT-PCR. Corticosteroids, anakinra, intravenous immunoglobulin (IVIG), and acetylsalicylic acid were used in the treatment. Three patients recovered after the treatment while one patient died. The literature review revealed 36 articles describing 320 children with Kawasaki-like disease associated with COVID-19. SARS-CoV-2 RT-PCR was negative in 120 (65.5%) of 183 patients while the serology was positive in 130 (83.8%) of 155 patients. The therapeutic options have included IVIG, acetylsalicylic acid, tocilizumab, anakinra, enoxaparin, and methylprednisolone. Pediatric COVID-19 cases may present with atypical/incomplete Kawasaki-like disease. Thus, pediatricians need to be aware of such atypical presentations resembling KD for early diagnosis of COVID-19.

In the medical literature, some case reports on the association of the COVID-19 infection and occurrence of spontaneous subarachnoid hemorrhage (SAH)have been reported Aim of the present paper is to search the causes of this association The diagnosis of COVID-19 was based on the real-time reverse-transcription polymerase chain reaction (PCR) test and computed tomography (CT) of the chest. There were four patients, whose median ages were 46,758, ranged 36–54 years). In conclusion, Spontaneous SAH can occur in the early and late course of COVID-19 infection. Its early recognition of the patient with spontaneous SAH is imperative. Highlights • Subarachnoid hemorrhage (SAH) has been reported in patients with Covid-19 infection, but it has not been well studied. • There is limited knowledge on the SAH following COVID-19 at present. • There is likely a direct association between the occurrence of SAH and COVID-19 through various potential mechanisms. • SAH may occur in the early and late course of COVID-19 infection.

COVID-19 virüsü kamu sağlığını tehdit etmektedir; dolayısıyla tüm toplumun bilinçli bir şekilde hareket etmesi de önem kazanmaktadır. Bu bilinç ise ancak doğru bilgilendirme ile gerçekleşebilmektedir. İçinde olduğumuz gibi dönemlerde toplumda her türlü platforma erişebilen bireylere bile doğru ve hızlı bilgi iletilmesi zorludur. Bilginin doğru ve hızlı yayılımı için atılması gereken adımların önünde ise bazı engellerin olduğu yadsınamaz. Sağır topluluk, çalışmada irdeleneceği üzere, toplumun diğer üyelerinden bazılarından farklı olarak pandemi sürecinde güvenilir kaynaklarda yayımlanan bilgilere erişimde ek zorluklar yaşamıştır. Çalışmada Sağır topluluğun Türkiye’de en temel pandemi önlemi olarak görülen 14 Kurala erişimindeki farklı çevirileri, çevirilerin amaçları doğrultusunda incelenmektedir. Çalışmanın ilk bölümünde engelsiz erişim bağlamında Sağır topluluğun gerçekleri paylaşılmaktadır. İkinci bölümde ise ilk bölümdeki bilgiler ışığında 14 Kural ve Türk İşaret Diline (TİD) iki çevirisi irdelenmektedir. Çalışmanın sonuç bölümünde ise engelli bireyler için bilgilendirmenin önemi vurgulanmakta ve incelemeden elde edilen veriler çerçevesinde özellikle de pandemi gibi kriz süreçlerinde farklı platformlardan ve farklı yaklaşımlarla doğru çevirilerin sunulmasının önemi üzerinde durulmaktadır.

A total of 1097 respondents took part in the survey. Well-being was measured by the World Health Organization (WHO) Well-being Index, stress was evaluated using a psychological stress measure (PSM-9) instrument, burnout was evaluated using the Copenhagen Burnout inventory, and digital competence was measured by the Digital Competency Profiler (DCP).Results: The results revealed that social and informational dimensions of digital competencies had a positive influence on dealing with stress or burnout and improved well-being of students studying online during the COVID-19 lockdown. Moreover, the analysis on a country level highlighted that with regard to dealing with stress and burnout, the epistemological dimension of digital competence was the most important for Lithuanians and Indians, the informational dimension for Polish students and the social dimension for Turkish students.Conclusion: The findings support the importance of digital competence on perceived stress, burnout and well-being among students studying online during the COVID-19 lockdown and propose deeper research directions on this phenomenon.Keywords: digital competence, online learning, stress, burnout, well-being, COVID-19

The novel Coronavirus infection disease is becoming more complex for the humans society by giving death and infected cases throughout the world. Due to this infection, many countries of the world suffers from great economic loss. The researchers around the world are very active to make a plan and policy for its early eradication. The government officials have taken full action for the eradication of this virus using different possible control strategies. It is the first priority of the researchers to develop safe vaccine against this deadly disease to minimize the infection. Different approaches have been made in this regards for its elimination. In this study, we formulate a mathematical epidemic model to analyze the dynamical behavior and transmission patterns of this new pandemic. We consider the environmental viral concentration in the model to better study the disease incidence in a community. Initially, the model is constructed with the derivative of integer-order. The classical epidemic model is then reconstructed with the fractional order operator in the form of Atangana–Baleanu derivative with the nonsingular and nonlocal kernel in order to analyze the dynamics of Coronavirus infection in a better way. A well-known estimation approach is used to estimate model parameters from the COVID-19 cases reported in Saudi Arabia from March 1 till August 20, 2020. After the procedure of parameters estimation, we explore some basic mathematical analysis of the fractional model. The stability results are provided for the disease free case using fractional stability concepts. Further, the uniqueness and existence results will be shown using the Picard–Lendelof approach. Moreover, an efficient numerical scheme has been proposed to obtain the solution of the model numerically. Finally, using the real fitted parameters, we depict many simulation results in order to demonstrate the importance of various model parameters and the memory index on disease dynamics and possible eradication.

Abstract COVID‐19 is a febrile, infectious illness that has previously been associated with telogen effluvium (TE). However, to date, no study has been conducted to determine the incidence of TE in those who have had COVID‐19. To assess the frequency of TE in post‐COVID‐19 patients and the correlation between the development of TE and the severity of COVID‐19, to understand whether emotional stress or medications are responsible for the development of TE. Totally 204 patients with a history of SARS‐CoV‐2 infection in the last 3 months were included in the study. The diagnosis of TE was made by history of excessive hair shedding, hair pull test, diffuse or bitemporal thinning, and absence of anisotrichosis in trichoscopy. Patients who did not have any TE cause other than COVID‐19 and whose hair loss started after COVID‐19 were considered as “COVID‐19 associated TE (CATE).” We found TE in 75 (36.7%) cases and androgenetic alopecia (AGA) in 85 (41.7%) cases. CATE was present in 27.9% of cases and developed on average 53.76 (± 23.772) days after COVID‐19 real‐time reverse transcription polymerase chain reaction (RT‐PCR) positivity. The proportion of patients with CATE was numerically higher in hospitalized patients compared to outpatients (31.7% vs. 24.3%; p = 0.238); and significantly higher in women compared to men (42.3% vs. 6.2%; p < 0.001), in patients with hypertension compared to those without hypertension (40.4% vs. 23.1%; p = 0.014), and in patients who had respiratory symptoms compared to those who had not (31.7% vs. 14.0%; p = 0.021). The patients with and without CATE were similar in terms of stress level and usage of COVID‐19 medications. Patients with AGA had a higher rate of hospitalization (69.4% vs. 35.3%; p < 0.001) and a higher incidence of fever (69.4% vs. 54.6%; p = 0.033) during COVID‐19, compared to those without. TE developed in approximately one‐quarter of people who have had COVID‐19, and our study is the first to detect it. The time to onset of CATE, which was 7–8 weeks after the SARS‐CoV‐2 RT‐PCR positivity, was not much different from post‐infectious TE. Patients with severe COVID‐19 seem to be more prone to develop TE. The presence of AGA is associated with a more severe COVID‐19. During the pandemic, clinicians should consider a previous SARS‐CoV‐2 infection in patients presenting with hair loss.

Bu çalışma, Covid-19 pandemisi sonrası meydana gelebilecek olası şoklar karşısında bankacılık sektörünün sermaye yeterlilik ve likidite rasyolarının ne düzeyde etkileneceğini araştırmaktadır. Bankaların 2019 mali verileri ve rasyoları BDDK’dan alınarak veri seti oluşturulmuştur. İki aşamadan oluşan analizde, olası şoklar karşısında bankaların sermaye yeterlilik ve likidite rasyolarının dayanıklılığı araştırılmıştır. Stres testinin ilk aşamasında, bankaların verilen kredilerde belirli oranlarda takip oluşması durumunda sermaye yeterlilik oranındaki değişimler analiz edilmiş ve şoklar doğrultusunda banka türleri arasında dayanıklılık mukayesesi yapılmıştır. Stres testinin ikinci aşamasında yine banka türlerine göre toplanan fonlarda belirlenen oranlarda kayıp oluşması durumunda likidite rasyolarındaki değişimler analiz edilmiştir. Analizlerde elde edilen bulgulara göre sektörde yer alan bankaların ekonomide yaşanabilecek olumsuz senaryolara karşı dayanıklı oldukları gözlemlenmiştir. Analizin her iki aşamasında Covid-19 pandemi sonrası olası şoklara karşı Yerli-Yabancı sermayeli Mevduat Bankalarının sermaye ve likidite yeterliliğinde en güçlü pozisyonda olduğu, bununla beraber en zayıf banka türünün ise Kamu sermayeli mevduat bankalarının olduğu tespit edilmiştir. This paper investigates the banking sector’s capital adequacy and liquidity ratios that potential shocks might influence following the COVID-19 pandemic. The data set was built using 2019 BRSA financial data and bank rates. The study is a two-stage investigation examining the resilience of banks’ capital adequacy and liquidity ratios against various shocks. The first stage is a stress test that evaluates the changes in the capital adequacy ratio for banks with specific nonperforming loan rates on issued loans; a comparison among bank types has also been made in terms of their resilience in response to shocks. The second stage examines changes in liquidity ratios concerning bank types in the event of a loss at the set rates in the funds collected. Based on the findings, the banking sector is resistant to bad scenarios in the economy. Both stages of the study have determined domestic-foreign deposit banks to have the strongest position in terms of capital and liquidity adequacy against probable shocks following the COVID-19 pandemic, whereas state-owned deposit banks have the weakest.

Study question: how did coronavirus disease 2019 (COVID-19) impact on medically assisted reproduction (MAR) services in Europe during the COVID-19 pandemic (March to May 2020)? Summary answer: MAR services, and hence treatments for infertile couples, were stopped in most European countries for a mean of 7 weeks. What is known already: with the outbreak of COVID-19 in Europe, non-urgent medical care was reduced by local authorities to preserve health resources and maintain social distancing. Furthermore, ESHRE and other societies recommended to postpone ART pregnancies as of 14 March 2020. Study design size duration: a structured questionnaire was distributed in April among the ESHRE Committee of National Representatives, followed by further information collection through email. Participants/materials setting methods: the information was collected through the questionnaire and afterwards summarised and aligned with data from the European Centre for Disease Control on the number of COVID-19 cases per country. Main results and the role of chance: by aligning the data for each country with respective epidemiological data, we show a large variation in the time and the phase in the epidemic in the curve when MAR/ART treatments were suspended and restarted. Similarly, the duration of interruption varied. Fertility preservation treatments and patient supportive care for patients remained available during the pandemic. Large scale data: N/A. Limitations reasons for caution: data collection was prone to misinterpretation of the questions and replies, and required further follow-up to check the accuracy. Some representatives reported that they, themselves, were not always aware of the situation throughout the country or reported difficulties with providing single generalised replies, for instance when there were regional differences within their country. Wider implications of the findings: the current article provides a basis for further research of the different strategies developed in response to the COVID-19 crisis. Such conclusions will be invaluable for health authorities and healthcare professionals with respect to future similar situations. Study funding/competing interests: there was no funding for the study, apart from technical support from ESHRE. The authors had no COI to disclose. NA
