Low-inflammatory lipid nanoparticle-based mRNA vaccine elicits protective immunity against H5N1 high-pathogenicity avian influenza virus with reduced adverse reactions.

Messenger RNA vaccines based on lipid nanoparticles (mRNA-LNPs) are promising vaccine modalities. However, mRNA-LNP vaccines frequently cause adverse reactions such as swelling and fever in humans, partly due to the inflammatory nature of LNP. Modification of the ionizable lipids used in LNP is one approach to avoid these adverse reactions.

Three-year follow-up outcomes of postoperative quality of life from a randomized controlled trial comparing multi-port versus single-port laparoscopic distal gastrectomy.

Background: Laparoscopic surgery for gastric cancer has become widely used; minimally invasive surgery has become the mainstream of treatment. This randomized controlled trial (RCT) aimed to compare long-term quality of life (QoL) and weight loss rates in patients who underwent single-port laparoscopic gastrectomy (SLG) or multi-port laparoscopic gastrectomy (MLG) for gastric cancer.

Methods: This single-center RCT compared MLG and SLG in patients with clinical stage I gastric cancer, all of which underwent distal gastrectomy between April 2016 and September 2018.
