Sexually Transmitted Infections

731
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Diseases of the Liver and Gallbladder

1.7K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Teratogenicity01:07

Teratogenicity

3.8K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

576
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Area of Science:

  • Hepatology
  • Virology
  • Maternal-Fetal Medicine

Background:

  • Hepatitis E virus (HEV) typically causes self-limiting hepatitis but presents severe risks in pregnant women.
  • Infection during the third trimester is linked to up to 30% mortality, preterm labor, and vertical transmission.
  • HEV is a global health issue with diverse transmission routes (fecal-oral, zoonotic, transfusion).

Purpose of the Study:

  • To review current knowledge on HEV infection during pregnancy.
  • To focus on epidemiology, clinical features, mechanisms of liver injury, and management strategies.
  • To highlight the need for early screening, monitoring, and further research into pathogenesis.

Main Methods:

  • Literature review of HEV infection in pregnancy.
  • Synthesis of data on epidemiology and clinical manifestations.
  • Analysis of factors contributing to disease severity and potential treatments.

Main Results:

  • HEV infection in pregnancy can lead to severe outcomes, including high mortality rates.
  • Altered immune status, hormonal changes, and viral factors may influence disease severity.
  • No established treatment exists, and vaccine efficacy in pregnant populations requires further study.

Conclusions:

  • HEV infection during pregnancy necessitates early screening and monitoring.
  • Understanding HEV pathogenesis is key to developing targeted treatments.
  • Further research is needed to establish effective management and prevention strategies for pregnant women.
