The virus sub-typing is done based on the two important viral surface glycoproteins such as Hemagglutinin (HA) and Neuraminidase (NA). The HA is involved in virus entry into the cell and NA in its release from the cell, thus playing an important role in influenza virus replication cycle. Till date, 16 HA and 9NA subtypes have been detected in birds, thus AIV can reemerge into 144 possible combinations [1].

At the end of 2019, a few cases of high contagious flu were reported in the Wuhan, China. The death ratio is very high. Some common high-risk patients are cardiovascular disease patients, cancer patients, pregnant women, and foetuses. Ultra-Care is necessary for those pregnant women who are admitted for caesarean section surgery. Society of Obstetric Anesthesia and Perinatology revealed that in elective caesarean surgery the pregnant women should be a screen for the symptoms of COVID-19 before the procedure. During surgery along with other management, anaesthetic drugs are a key priority element. Among pregnant women, the safest anesthesia for caesarean with COVID-19 is Combine Spinal Epidural Anesthesia (CSEA). In emergency, caesarean surgery of COVID-19 patient general anesthesia with rapid sequence induction and the endotracheal tube is administered. It is recommended that pregnant women should be properly examined for symptoms of COVID-19 before surgery. The healthcare staff should wear proper PPE to avoid the spread of the virus. It is concluded that patient with other disease has increased the morbidity rate up to three-fold. The spinal and epidural anesthesia are safe for elective surgery of pregnant women.","PeriodicalId":15020,"journal":{"name":"Journal of Antivirals & Antiretrovirals","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90100987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Combo Compound Therapy Effectively Reduces SARS-CoV-1 Viral Load in Mouse Lung","authors":"J. Tunac","doi":"10.37421/1948-5964.21.13.221","DOIUrl":"https://doi.org/10.37421/1948-5964.21.13.221","url":null,"abstract":"Objective: SARS-CoV disease caused by SARS-CoV-1 is of multifactorial etiology consisting of upstream and downstream phases. The upstream phase is the physical breach of the cells protective shield by extraneous stressors including the virus and environmental elements (xeno), while the downstream is a sequela of damages (plexic) manifested in various symptoms, herein called xenoplexic diseases. Symptom targeting drugs are ineffective and palliative at best. SARS-CoV is a xenoplexic disease best treated with a combo therapeutic strategy This study evaluates EmbotricinTM (EMB), a multicomponent compound, to treat SARS-CoV. Materials and methods: Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-1), strain Urbani (200300592), obtained from the Centers for Disease Control and Prevention (CDC, Atlanta, GA) was used as the test virus. Female BALB/C mice obtained from Charles River Laboratories (Wilmington, MA) were the animal host. New Chemical Entities (NCE) including FTX-214, FTX-218, and FTX-219 were formulated as a 3-component combo, herein called Embotricin (EMB). Also, a 4-component compound consisting of EMB plus sodium thiosulfate was evaluated. The 3- and 4-combo compounds were administered 2 days prior to infection, given by per os (PO) daily (q.d.) for 5 days. Poly I:C, a known antiviral compound acting as an immunomodulator was used as a comparative control, administered intraperitoneally (IP). Results: EMB at 3.1 mg/kg fixed dose (1:1:1 ratio) combo reduced viral load by 14.4% compared to 11.8% for poly I:C at 10 mg/kg dose. Addition of sodium thiosulfate (4-combo formulation) further boosted the activity to 16.6%. Increasing the 4-combo dosages to 4.65 mg/kg and 6.2 mg/kg further increased activity to 18.2% and 20.9%, respectively. Conclusion: The individual components synergistically targeted the upstream disease etiology and restore in toto the health of the cell to ward off SARS-CoV-1. Thus, combo therapy may well be a universal platform to treat xenoplexic diseases where monotherapies fail. The combo therapy effectively reduced the viral load of SARS-CoV-1, not by directly inhibiting the virus, but most likely due to enhancing the health of the cell.","PeriodicalId":15020,"journal":{"name":"Journal of Antivirals & Antiretrovirals","volume":"367 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84917293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
