Background: Covered stent correction for a sinus venosus atrial septal defect (SVASD) was first performed in 2009. This innovative approach was initially viewed as experimental and was reserved for highly selected patients with unusual anatomic variants. In 2016, increasing numbers of procedures began to be performed, and in several centers, it is now offered as a standard of care option alongside surgical repair.

Methods: Two hundred forty-three children underwent initial intervention between 1997 and 2022, by surgical valvuloplasty in 92 (32% neonates, 36% infants) and balloon valvuloplasty in 151 (27% neonates, 30% infants). Twenty-eight patients (11.
Article Synopsis
- Hepatitis A virus (HAV) is primarily transmitted through the faecal-oral route and can exist as both naked and enveloped particles, with enveloped HAV (eHAV) being the focus of most studies.
- A new method has been developed that involves chemically removing the lipid bilayer from eHAV to produce naked HAV particles without losing their ability to infect.
- These naked HAV particles can be cultivated in vitro and are valuable for further research, particularly in food safety studies aimed at understanding how to inactivate the virus.
Article Synopsis
- Tick-borne encephalitis (TBE) outbreaks in Europe have been linked to the consumption of raw milk products, highlighting a need for better detection methods of the virus in these foods.
- Researchers developed a sensitive cell culture-based method for detecting infectious TBEV in artificially contaminated raw goat milk and cheese, achieving varying levels of viral detection.
- The study showed that this method successfully identified infectious TBEV in both milk and cheese samples, supporting its potential use in future foodborne outbreak investigations.
