In response to the COVID-19 pandemic, many countries have adopted community containment to manage COVID-19. These measures to reduce human contact, such as social distancing, are deemed necessary to contain the spread of the virus and protect those at increased risk of developing complications following infection with COVID-19. People with rheumatoid arthritis (RA) are advised to adhere to even more stringent restrictions compared to the general population, and avoid any social contact with people outside their household. This social isolation combined with the anxiety and stress associated with the pandemic, is likely to particularly have an impact on mental health and psychological wellbeing in people with RA. Increasing physical activity and reducing sedentary behaviour can improve mental health and psychological wellbeing in RA. However, COVID-19 restrictions make it more difficult for people with RA to be physically active and facilitate a more sedentary lifestyle. Therefore, guidance is necessary for people with RA to adopt a healthy lifestyle within the constraints of COVID-19 restrictions to support their mental health and psychological wellbeing during and after the COVID-19 pandemic.The magnitude of the SARS-CoV-2 pandemic found health systems unprepared, not allowing for prompt evaluation, collaboration among specialities and treatment of severely ill patients admitted to intensive care units, with many of them having an unfortunate outcome. Current data demonstrate an acute immune dysregulation in severe forms of the disease. The above is concluded by clinical evolution and laboratory findings, indicating a severe inflammatory response of the innate immune system, initiating predominately with the involvement of the respiratory tract epithelial cells, occasionally progressing to thrombotic diathesis and related complications. Besides the clinical manifestations, the immune response expresses an extremely high acute phase reactants repertoire including hyperferritinemia, hyper-fibrinogenaemia, and a storm of cytokines that require an alternative view and collaboration with rheumatologists. Thrombotic diathesis in some cases may not attribute only to a possible disseminated intravascular coagulation, but also to an additional activation of adaptive immunity and the development of the antiphospholipid syndrome. Unifying speciality evaluation and treatment may improve patient outcomes by recognizing early the evolving syndromes, treating properly, in a stratifying manner, with medications that alleviate the inflammatory reaction. Corticosteroids, colchicine, hydroxychloroquine/chloroquine, and possibly potent immunosuppressants are in the armamentarium. Additionally, biologics that interrupt the innate immune dysfunction, such as IL-1, IL-6 and selective JAK inhibitors, are also used. Convalescent plasma therapy and human immunoglobulin may be restricted for those whom the proposed treatments are found inadequate. The above combined with antiretroviral medications may improve the outcome until the development of safe and effective vaccination.The recent passing away of Dr. Tomisaku Kawasaki, who first described what is now known as Kawasaki Disease (KD), and recent reports of a multisystem inflammatory disease in children associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (MIS-C), makes a review on KD and MIS-C timely. Kawasaki Disease is a systemic vasculitis with predilection for coronary arteries occurring mostly in early childhood. The main features are high fever, extensive skin rash, cheilitis with red, cracking, bleeding lips and strawberry tongue, conjunctivitis, erythema and induration of hands and feet, subsiding with periungual peeling, cervical lymphadenopathy, and coronary artery dilation/aneurysms. Treatment consists of intravenous (IV) immunoglobulin (Ig) plus acetylsalicylic acid. MIS-C is considered a cytokine storm with high fever, inflammation, multi-organ dysfunction, that shares features with KD, toxic shock, and macrophage activation syndrome. Many children require admission to paediatric intensive care units for circulatory support. Bacterial sepsis, staphylococcal toxic shock syndrome, and enterovirus-causing myocarditis should be excluded. Treatment is not standardized and includes IVIg, IV methylprednisolone and IL-6 and IL-1 inhibitors.SARS-CoV-2 is a positive-sense single-stranded RNA virus that causes the COVID-19 infection. Spike proteins are the most important proteins found on its capsule using the host's ACE2 receptors to invade respiratory cells. The natural course of the COVID-19 infection is variable, from asymptomatic to severe and potentially fatal. A small percentage of the severely infected patients will end up in an intensive care unit for ventilatory support. Elderly male patients with pre-existing medical conditions and smokers are at a disproportionate high risk to develop severe complications. Studies have shown that deaths occur due to a dysregulated immune system that overreacts, producing a plethora of cytokines, leading to the so-called "cytokine storm" phenomenon. In this direction, many drugs that are used in the everyday practice of Rheumatologists have been used. Indeed, pro-inflammatory cytokines such as the IL-1 and IL-6 have been shown to be the pivotal cytokines expressed, and anti-cytokine treatment has been tried so far with various results. In addition, hydroxychloroquine, an antimalarial drug, has been shown to reduce COVID-19 symptoms. Other drugs have also been used, such as intravenous pulses of immunoglobulins, and colchicine. Robust clinical trials are needed in order to find the suitable treatment. Napabucasin purchase Current data indicate that hydroxychloroquine and cytokine targeting therapies may prove helpful in the fight of SARS-CoV-2 in appropriately selected patients.The global coronavirus disease 2019 (COVID-19) situation threatens not only the health of populations, but also the coherence and function of health care systems. Patients with systemic inflammatory disorders feel the overwhelming strain of COVID-19, since their disease, administered treatments, and associated comorbidities may all contribute to increased vulnerability to infection. At the same time, monitoring the activity status of rheumatic diseases and adjusting the treatments where appropriate, are important for preventing flares and other complications, which could pose additional health risks. Considering the urgent need to maintain physical distancing and self-quarantine as much as possible, we herein discuss the challenges and possible solutions pertaining to the assessment and monitoring of patients with systemic inflammatory diseases. We also discuss issues related to the prescription and supply of anti-rheumatic drugs, as well as opportunities provided by the use of technological and wireless tools. From an optimistic viewpoint, the end of this pandemic may leave us with an important legacy in utilising and implementing e-health solutions that may both improve the clinical care standards for patients with systemic inflammatory diseases and also reduce the burden placed on healthcare systems.As the worldwide burden of COVID-19 increases exponentially, healthcare systems are plagued by unprecedented pressure. In this setting, many rheumatologists across the globe have been recruited to support the front line, facing several unexpected challenges, but also providing valuable skills in combating COVID-19. At the same time, the rheumatic disease patient population may be especially vulnerable to such a rapidly contagious infectious disease and thus needs care and support that has to be provided quickly and efficiently. Clear advice on viral spread mitigation, precise guidelines on immunosuppressive treatment use and alternative methods of providing care, such as telemedicine, are a few of the rheumatologists' new challenges in caring for their patients in the COVID-19 era. Finally, among other specialties, rheumatologists hold a unique place in the fight against the hyper-inflammatory state caused by severe SARS-CoV-2 infection, leading to increased morbidity and mortality. Given their vast experience in the use of biologic and targeted therapies, rheumatologists should lead the way in developing reliable scientific evidence for the optimal treatment of severe COVID-19.The flow of information on Coronavirus Disease 2019 (COVID-19) is intensifying, requiring concerted efforts of all scholars. Peer-reviewed journals as established channels of scientific communications are struggling to keep up with unprecedented high submission rates. Preprint servers are becoming increasingly popular among researchers and authors who set priority over their ideas and research data by pre-publication archiving of their manuscripts on these professional platforms. Most published articles on COVID-19 are now archived by the PubMed Central repository and available for searches on LitCovid, which is a newly designed hub for specialist searches on the subject. Social media platforms are also gaining momentum as channels for rapid dissemination of COVID-19 information. Monitoring, evaluating and filtering information flow through the established and emerging scholarly platforms may improve the situation with the pandemic and save lives.The Chicago Board Options Exchange Volatility Index (VIX) is considered by many market participants as a common measure of market risk and investors' sentiment, representing the market's expectation of the 30-day-ahead looking implied volatility obtained from real-time prices of options on the S&P 500 index. While smaller deviations between implied and realized volatility are a well-known stylized fact of financial markets, large, time-varying differences are also frequently observed throughout the day. Furthermore, substantial deviations between the VIX and its futures might lead to arbitrage opportunities on the VIX market. Arbitrage is hard to exploit as the potential strategy to exploit it requires buying several hundred, mostly illiquid, out-of-the-money (put and call) options on the S&P 500 index. This paper discusses a novel approach to predicting the VIX on an intraday scale by using just a subset of the most liquid options. To the best of the authors' knowledge, this the first paper, that describes a new methodology on how to predict the VIX (to potentially exploit arbitrage opportunities using VIX futures) using most recently developed machine learning models to intraday data of S&P 500 options and the VIX. The presented results are supposed to shed more light on the underlying dynamics in the options markets, help other investors to better understand the market and support regulators to investigate market inefficiencies.New data specific to COVID-19 are emerging quickly on key issues of immunity and prevention, but past research in coronavirology and for other human pathogens (e.g., Mycoplasma pneumoniae) has been available and of great relevance. Considerable study of endemic human coronaviruses has shown that neutralizing antibody correlates with protection, but effective clinical protection is variable for subsequent virus exposure. Animal coronavirus research has emphasized the importance of local mucosal protection (especially IgA) and systemic responses. Animal model and human post-infection studies for SARS-CoV and MERS-CoV are largely corroborative. Whether for passive therapeutic strategies or vaccination, these findings provide a template for COVID-19. Many approaches to vaccination have emerged, and there may be more than one vaccine that will be applied, but individualized obstacles and concerns for administration, efficacy, and safety are inevitable. Regardless of safeguards or promises that may be understood from laboratory or vertebrate experiments, observations from large-scale human trials will ultimately prove to shape the medical future.
