ABSTRACT
Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has infected many people around the world. Children are considered an important target group for SARS-CoV-2, as well as other viral infections such as respiratory syncytial virus infection. Both SARS-CoV-2 and respiratory syncytial virus can affect the respiratory tract. Coinfection of SARS-CoV-2 and respiratory syncytial virus can pose significant challenges in terms of diagnosis and treatment in children. This review compares the symptoms, diagnostic methods, and treatment of COVID-19 and respiratory syncytial virus infection in children.
ABSTRACT
Background and Aims: Hepatitis E virus [HEV] is considered as one of the common causes of acute viral hepatitis in the world, particularly in the developing countries. It also causes fulminant hepatitis in pregnant women. Although HEV infection in Iran is endemic, there are numerous reports of epidemics caused by this infection in this part of the world. This study aimed to determine seroprevalence of HEV among patients with acute hepatitis symptoms in Ahvaz, Iran
Materials and Methods: In this cross-sectional study patients were selected based on laboratory findings related to acute hepatitis including elevated serum bilirubin levels, markedly elevated levels of liver enzymes such as alanine aminotransferase, aspartate aminotransferase and mild increases in alkaline phosphatase activity.The plasma samples were tested for IgM/IgG Hepatitis E antibody [anti-HEV] using enzyme-linked immunosorbent assay
Results: Out of 241 study patients, 125 [51.9%] were male and 116 [48.1%] female. The mean age+/-SD was 31.53+/-17.17 years. The results indicated 27.4% prevalence of anti-HEV antibodies among patients with acute hepatitis in Ahvaz
Conclusions: In regard with the findings, HEV can play an important role in incidence of hepatitis. The study needs to be conducted in high-risk groups and in general populatios
ABSTRACT
Sea cucumber is a traditional food and medical item and has been reported to exhibit Antioxidant, antifungal, anti tumoral and antibacterial bioactivity. The objective of this study is to describe the antibacterial activity of 4 extracts of Holoturia. Sp [sea cucumber], collected from Hengam Island of Persian Gulf. Methanol, hexane, aqueous and chloroform extracts from body wall tissue of the sea cucumber were screened for antibacterial activity against three strains of Escherichia coli Top 10 F', TG1 and K12 using disc diffusion and broth microdilution tests methods. The growth of all these strains were inhibited using concentration from 0.78 to 100 mg/ml of methanol, hexan and chloroform extracts. Among the extracts just methanol and chloroform with 100 mg/ml had bactericidal effect on TG1 and K12 strains. On the other hand, Aqueous extract had induced growth in of the all strains. The results suggest the possibility of applying sea cucumber as source of potential anti bacterial agents, whose compounds can be good candidates to make antibiotic products
