In the Wuhan province of China, almost two years ago, in December 2019, the novel Coronavirus 2019 has caused a severe involvement of the lower respiratory tract leading to an acute life-threatening respiratory syndrome, coronavirus disease-19 (COVID-19). Subsequently, coronavirus 2 (SARS-CoV-2) rapidly spread to the entire world causing a pandemic and affected every single person on earth either directly or indirectly with destroying all facets of social life and economy. Since the announcement of COVID-19 as a global pandemic, we have witnessed tremendous scientific work on all aspects of COVID-19 across the globe, which has never been witnessed before. ⋯ Immune deficiency, being on corticosteroids for inflammatory diseases, delayed interferon response and advanced age adversely influence prognosis with impairing viral clearance. On the other hand, exuberant immune response with features of cytokine storm is the leading cause of death, which can be alleviated by use of either general immunosuppression with corticosteroids or selective neutralization of potent pro-inflammatory cytokines such as interleukin (IL)-1 and IL-6. Herein, we summarized the potential effective immunomodulatory treatments emphasizing in which patient population it is the most suitable, which dose should be administered, and which is the most appropriate timepoint to administer the drug during the course of the disease.

SARS-CoV-2 B.1.1.529 (Omicron) Variant - United States, December 1-8, 2021.
A new variant of SARS-CoV-2 (the virus that causes COVID-19), B.1.1.529 (Omicron) (1), was first reported to the World Health Organization (WHO) by South Africa on November 24, 2021. Omicron has numerous mutations with potential to increase transmissibility, confer resistance to therapeutics, or partially escape infection- or vaccine-induced immunity (2). On November 26, WHO designated B.1.1.529 as a variant of concern (3), as did the U. ⋯ This report summarizes U. S. surveillance for SARS-CoV-2 variants, characteristics of the initial persons investigated with COVID-19 attributed to the Omicron variant and public health measures implemented to slow the spread of Omicron in the United States. Implementation of concurrent prevention strategies, including vaccination, masking, increasing ventilation, testing, quarantine, and isolation, are recommended to slow transmission of SARS-CoV-2, including variants such as Omicron, and to protect against severe illness and death from COVID-19.

Although we have enough and cumulative information about acute effects of COVID-19, our knowledge is extremely limited about long-term consequences of COVID-19, in terms of its impacts and burdens on patients, families, and the health system. Considering the underlying pathophysiological mechanisms affecting all of the organ systems in critically ill COVID-19 patients who are admitted to intensive care units, the development of post-intensive care syndrome is inevitable. ⋯ These patients should be followed regarding cognitive, physical, and psychiatric aspects and necessary specialist referrals should be carried out. In this article, we are presenting the experience and recommendations of our center, as a guide for the establishment process of post-intensive care outpatient clinics for the critically ill patients who required intensive care admission due to COVID-19 and could be discharged.

As the COVID-19 pandemic continues, children can be infected with the virus that causes COVID-19. Clinical symptoms of children with COVID from China, where the disease was first reported, generally were less severe than adults. However, at the end of April 2020 in Europe, it was observed that some children with SARS-CoV-2 infection developed fever, abdominal pain, shock, myocardial insufficiency and they needed to be taken care of in intensive care unit. ⋯ Although the pathogenesis of MIS-C is unclear, it progresses with signs of multiorgan involvement as a result of uncontrolled inflammation of the immune system and even causes death. Therefore, the diagnosis and treatment of patients with MIS-C should be managed quickly. In this review, the pathophysiology, clinical and laboratory findings, diagnostic methods, and treatment regimens of MIS-C were discussed.

Mobilizing the research ecosystem for accelerating vaccine and drug development has been an important reality of the pandemic. This article reviews the scientific advances that are attained by the COVID-19 Turkey Platform for vaccine and drug development against the SARS-CoV-2 virus. The platform that is coordinated by the Scientific and Technological Research Council of Turkey is established with a "co-creation and succeeding together" approach, which involves 436 researchers across 49 different institutions working on 17 vaccine and drug development projects in total. ⋯ Moreover, an adjuvanted inactivated vaccine candidate and two drug candidates that have been identified through the virtual scanning of more than 20,000 molecules are currently in clinical studies. Other vaccines and drug candidates involve additional innovative aspects, and a locally synthesized drug is found to have an impact on COVID-19. This review article discusses the advances that are achieved by the COVID-19 Turkey Platform from the ecosystem perspective, emphasizing the important scientific advances that have been achieved in the field of medical sciences.
