The Impact on Patient Prognosis of Changes to the Method of Notifying Staff About Accepting Patients With Out-of-Hospital Cardiac Arrest.

Background: Our hospital is a designated emergency hospital and accepts many patients with out-of-hospital cardiac arrest (OHCA). Previously, after receiving a direct call from emergency services to request acceptance of an OHCA patient, the emergency room (ER) chief nurse notified medical staff. However, this method delayed ER preparations, so a Code Blue system (CB) was introduced in which the pending arrival of an OHCA patient was broadcast throughout the hospital.

Comparison of self-reported symptoms in COVID-19 patients who had or had not previously received COVID-19 mRNA vaccination.

Although mRNA coronavirus disease 2019 (COVID-19) vaccines have been reported for high effectiveness against symptoms, it remains unclear whether post-vaccination infections are less symptomatic than infections in vaccine-naive individuals. We included patients with COVID-19 diagnosed by polymerase chain reaction tests during Japan's alpha and delta variant epidemics. COVID-19 symptoms at approximately 4 weeks were compared based on COVID-19 vaccination status.

Real-World Effectiveness of the mRNA COVID-19 Vaccines in Japan: A Case-Control Study.

The real-world effectiveness of the coronavirus disease 2019 (COVID-19) vaccines in Japan remains unclear. This case-control study evaluated the vaccine effectiveness (VE) of two doses of mRNA vaccine, BNT162b2 or mRNA-1273, against the delta (B.1.

Novel plasmids for the fluorescence-based evaluation of DNA mismatch repair in human cells.

Mismatch repair (MMR) is a highly conserved DNA repair pathway that corrects mismatched bases during DNA replication. The biological significance of MMR in human cells is underscored by the fact that dysfunction of the MMR pathway results in Lynch syndrome, which is associated with a genetic predisposition to different cancer types. We have previously established a reporter mismatch plasmid to evaluate MMR using fluorescent proteins in living cells.
