Infection with the new corona virus (SARS-CoV-2) was first registered in December 2019 in China, and then later spread rapidly to the rest of the world. On December 31, 2019, the World Health Organization (WHO) informed the public for the first time about causes of pneumonnia of unknown origin, in the city of Wuhan (Hubei Province, China), in people who were epidemiologically linked to a seafood and wet animal whole sale local market in Wuhan. Coronavrus disease, called COVID-19 (Corona virus disease 2019), after China quickly spread to most countries in the wold, and the WHO on March 11, 2020 declared a pandmic with this virus. ⋯ From the current point of view, it seems that in COVID-19 survivors, in the coming years and decades, the inflammatory systemic process and/or the inflammatory process of the brain could trigger long-term mechanisms that generally lead to an increase of neurological and neurodegenerative disorders. Psychosocial consequences as well as consequences for mental health are also significant, both for the general population and especially for health workers of all profiles. COVID-19 pandemia is associtaed with negative psychosocial consequences, including depressive symptoms, anxiety, anger and stress, sleep disorders, simpotms of posttrauamtic stres disorder, social isolation, loneliness and stigmatization.

The recent outbreak of the novel coronavirus disease, COVID-19, has highlighted the threat that highly pathogenic coronaviruses have on global health security and the imminent need to design an effective vaccine for prevention purposes. Although several attempts have been made to develop vaccines against human coronavirus infections since the emergence of Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) in 2003, there is no available licensed vaccine yet. ⋯ In general, coronavirus spike protein is the major antigen for the vaccine design as it can induce neutralizing antibodies and protective immunity. By considering the high genetic similarity between SARS-CoV and SARS-CoV-2, here, protective immunity against SARS-CoV spike subunit vaccine candidates in animal models has been reviewed to gain advances that can facilitate coronavirus vaccine development in the near future.

Recent new zoonotic respiratory viruses have infected humans and led to severe acute respiratory syndrome: severe acute respiratory syndrome coronavirus (SARS-CoV), influenza A H5N1, influenza A H1N1 and Middle East respiratory syndrome coronavirus (MERS-CoV). The first SARS-CoV outbreak took place in 2003, in Guangdong, China. A decade later, another pathogenic coronavirus, MERS-CoV caused an endemic in Middle Eastern countries. ⋯ Several guidelines for dental practice environments have been published by dental associations and regulatory boards. It is already evident that biological, psychological and social effects of the COVID-19 pandemic have present and future impacts on dental practice. Dental schools, regulatory boards, scientific associations, government authorities, and public and private health care services must join efforts to design enduring answers for severe and long-standing viral challenges.

Whether the patients with coronavirus disease 19 (COVID-19) infected by severe acute respiratory syndrome (SARS)-CoV-2 would commonly develop acute kidney injury (AKI) is an important issue worthy of clinical attention. This study aimed to explore the effects of SARS-CoV-2 infection on renal function through analyzing the clinical data of 116 hospitalized COVID-19-confirmed patients. ⋯ AKI was uncommon in COVID-19. SARS-CoV-2 infection does not result in AKI, or aggravate CKD in the COVID-19 patients.

Meta AnalysisCOVID-19 infection in pregnant women, preterm delivery, birth weight, and vertical transmission: a systematic review and meta-analysis.
In less than four months, the total of confirmed cases of COVID-19 was 1,684,833 worldwide. Outcomes among the public of pregnant women with COVID-19 are still unclear. We performed a systematic review and meta-analysis to analyze whether COVID-19 in pregnant women is related to premature birth and birth weight, and to summarize the diagnostic results of neonates born to mothers with COVID-19 for investigating the possibility of vertical transmission. ⋯ Due to the characteristics of the studies, the level of evidence of this meta-analysis was considered very low. COVID-19 in pregnant women may not be associated with the occurrence of preterm deliveries or the birth weight of the newborn children, however the evidence to date is very uncertain. A few reports suggest vertical transmission of SARS-CoV-2 to newborn is possible, but evidence is still uncertain.
