Background: A recent conditional recommendation suggests considering live-attenuated vaccines for solid organ transplant recipients, yet the conditions of their safe and effective administration remain unclear.

Methods: This prospective study was conducted at Keio University Hospital from 2002 to August 2023. We gave a live-attenuated vaccine to liver transplant (LT) recipients fulfilling criteria for live-attenuated vaccines, including criteria for humoral and cell-mediated immunity.

Persistent colonization and outgrowth of potentially pathogenic organisms in the intestine can result from long-term antibiotic use or inflammatory conditions, and may perpetuate dysregulated immunity and tissue damage. Gram-negative Enterobacteriaceae gut pathobionts are particularly recalcitrant to conventional antibiotic treatment, although an emerging body of evidence suggests that manipulation of the commensal microbiota may be a practical alternative therapeutic strategy. Here we isolated and down-selected commensal bacterial consortia from stool samples from healthy humans that could strongly and specifically suppress intestinal Enterobacteriaceae.

Background: The annual administration of the influenza vaccine is the most effective method for preventing influenza. We have evaluated the effectiveness of the inactivated influenza vaccine in children aged 6 months to 15 years across the seasons from 2013/2014 to 2022/2023. This study aims to investigate the effectiveness of the inactivated influenza vaccine in the 2023/2024 season, the first year following the easing of strict COVID-19 measures, and possibly the last season when only the inactivated vaccine is available on the market.

Recently, live-attenuated measles, rubella, varicella, and mumps vaccines have been administered to carefully selected post-liver transplant patients. Although attention has been focused on post-vaccination antibody titers and adverse events, the real-life clinical benefits remain unclear. A comprehensive analysis of breakthrough infections and natural boosters (asymptomatic cases with significant elevation in virus antibody titers) following immunization post-liver transplantation was conducted from 2002-2023, exploring the timing, frequency, correlation with domestic outbreaks, and degree of antibody elevation.

Article Synopsis
  • Pseudohypoparathyroidism (PHP) is a rare disorder causing symptoms like convulsions and involuntary movements due to resistance to parathyroid hormone, resulting in low calcium levels.
  • A case study of a 7-year-old girl showed her involuntary movements were initially misdiagnosed and treated with carbamazepine but led to convulsions and revealed significant underlying electrolyte imbalances and brain calcifications.
  • Diagnosis was confirmed via genetic testing, and treatment with calcium and vitamin D resolved her symptoms, highlighting the importance of early blood tests for proper PHP diagnosis in patients with similar movement disorders.
