Merkel cell carcinoma in the child along with AIDS-related Kaposi sarcoma.
In a previous study, we identified a 117 base severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequence in the human genome with 94.6% identity. The sequence was in chromosome 1p within an intronic region of the netrin G1 (NTNG1) gene. The sequence matched a sequence in the SARS-CoV-2 Orf1b gene in non-structural protein 14 (NSP14), which is an exonuclease and NSP15, an endoribonuclease. In the current study we compared the human genome with other viral genomes to determine some of the characteristics of human sequences found in the latter. Most of the viruses had human sequences, but they were short. Hepatitis A and St Louis encephalitis had human sequences that were longer than the 117 base SARS-Cov-2 sequence, but they were in non-coding regions of the human genome. The SARS-Cov-2 sequence was the only long sequence found in a human gene (NTNG1). The related coronaviruses SARS-Cov had a 41 BP human sequence on chromosome 3 that was not part of a human gene, and MERS had no human sequence. The 117 base SARS-CoV-2 human sequence is relatively close to the viral spike sequence, separated only by NSP16, a 904 base sequence. The mechanism for SARS-CoV-2 infection is the binding of the virus spike protein to the membrane-bound form of angiotensin-converting enzyme 2 (ACE2) and internalization of the complex by the host cell. We have no explanation for the NSP14 and NSP15 SARS-Cov-2 sequences we observed here or how they might relate to infectiousness. Further studies are warranted.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a positive-sense single-stranded RNA virus. It is contagious in humans and is the cause of the coronavirus disease 2019 (COVID-19) pandemic. In the current analysis, we searched for SARS-CoV-2 sequences within the human genome. To compare the SARS-CoV-2 genome to the human genome, we used the blast-like alignment tool (BLAT) of the University of California, Santa Cruz Genome Browser. BLAT can align a user sequence of 25 bases or more to the genome. BLAT search results revealed a 117-base pair SARS-CoV-2 sequence in the human genome with 94.6% identity. The sequence was in chromosome 1p within an intronic region of the netrin G1 (NTNG1) gene. The sequence matched a sequence in the SARS-CoV-2 orf1b (open reading frames) gene. The SARS-CoV-2 human sequence lies within non-structural proteins 14 and 15 (NSP14 and NSP15), and is quite close to the viral spike sequence, separated only by NSP16, a 904-base pair sequence. The mechanism for SARS-CoV-2 infection is the binding of the virus spike protein to the membrane-bound form of angiotensin-converting enzyme 2 and internalization of the complex by the host cell. INCB084550 It is probably no accident that a sequence from the SARS-CoV-2 orf1b gene is found in the human NTNG1 gene, implicated in schizophrenia, and that haloperidol, used to treat schizophrenia, may also be a treatment for COVID-19. We suggest, therefore, that it is important to investigate other haloperidol analogs. Among them are benperidol, bromperidol, bromperidol decanoate, droperidol, seperidol hydrochloride, and trifluperidol. These analogs might be valuable in the treatment of COVID-19 and other coronavirus infections.The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in China in the city of Wuhan in December of 2019 and since then more than 5,000,000 people have been infected, with approximately 338,000 deaths worldwide. The virus causes the coronavirus disease 2019 (COVID-19), which is characterized by fever, myalgia and cough, with severe acute respiratory syndrome being the most fearsome complication. Nevertheless, the vast majority of cases present mild symptoms or none. Central nervous system and cardiovascular manifestations have been reported. The range of ocular manifestations, either as a result of the infection or as a result of the treatment, has not yet been discussed. In this study, a systematic review of current literature relevant to COVID-19 was performed with focus on modes of transmission, ocular manifestations related to infection and medications, as well as the control of infection in ophthalmic practice.Background/aim To evaluate the research trends in coronavirus disease (COVID-19). Materials and methods A bibliometric analysis was performed using a machine learning bibliometric methodology. Information regarding publication outputs, countries, institutions, journals, keywords, funding and citation counts was retrieved from Scopus database. Results A total of 1883 eligible papers were returned. An exponential increase in the COVID-19 publications occurred in the last months. As expected, China produced the majority of articles, followed by the United States of America, the United Kingdom and Italy. There is greater collaboration between highly contributing authors and institutions. The "BMJ" published the highest number of papers (n=129) and "The Lancet" had the most citations (n=1439). The most ubiquitous topic was COVID-19 clinical features. Conclusion This bibliometric analysis presents the most influential references related to COVID-19 during this time and could be useful to improve understanding and management of COVID-19.The aim of this systematic review was to identify the challenges imposed on medical and surgical education by the COVID-19 pandemic, and the proposed innovations enabling the continuation of medical student and resident training. A systematic review on the MEDLINE and EMBASE databases was performed on April 18th, 2020, and yielded 1288 articles. Sixty-one of the included manuscripts were synthesized in a qualitative description focused on two major axes, "challenges" and "innovative solutions", and two minor axes, "mental health" and "medical students in the frontlines". Shortage of personal protective equipment, suspension of clinical clerkships and observerships and reduction in elective surgical cases unavoidably affect medical and surgical education. Interesting solutions involving the use of virtual learning, videoconferencing, social media and telemedicine could effectively tackle the sudden cease in medical education. Furthermore, trainee's mental health should be safeguarded, and medical students can be involved in the COVID-19 clinical treatment if needed.
