Dental caries and periodontitis are the most common oral diseases in humans and the main causes of tooth loss. Streptococcus mutans is primarily responsible for dental caries and dental plaque, which are triggered by biofilm formation on the tooth surface. In this study, biofilm inhibition by 4-isopropyl-3-methylphenol (IPMP)-based agents, consisting of IPMP and polyoxyethylene-hydrogenated castor oil (POEHCO), was investigated in vitro.

- Nonocclusive mesenteric ischemia (NOMI) is rare in children but can occur after cardiac arrest, as highlighted in a case involving a 16-month-old boy in Japan who suffered from it post-resuscitation.* -
- The boy experienced cardiac arrest due to foreign body asphyxiation and required extensive resuscitation efforts, including 10 doses of adrenaline over a maximum arrest time of 95 minutes.* -
- After developing NOMI 40 hours later, he faced severe complications but was successfully treated with two surgical procedures and ultimately discharged, emphasizing the importance of timely intervention.*
Background: The use of continuous renal replacement therapy (CRRT) in critically ill children is rapidly increasing, but the standard of care has not yet been established and prognosis remains poor. To develop optimal CRRT strategies, we launched a research project generating the Japanese Pediatric CRRT registry, a multicenter registry of CRRT in Japanese pediatric intensive care units (PICUs), to investigate the actual status of CRRT in recent years in PICUs, where data are lacking.
Methods: This manuscript presents a protocol for planning a multicenter prospective registry.
Background: Home hot-tub bathing substantially increases drowning mortality rates among older adults in Japan. Previous laboratory studies on hemodynamic responses during hot-tub bathing have been inconsistent depending on the thermal conditions. Furthermore, real-world hemodynamic changes that occur during bathing remain poorly understood.

The purpose of this study was to compare daily light exposure between patients with Parkinson's disease (PD) and non-PD older adults and evaluate the association of daily light exposure with objective sleep measures in patients with PD.
Methods: In this cross-sectional study of 189 outpatients with PD and 1101 community-dwelling older adults (controls), daily light exposure was measured using wrist light meters during the daytime and light meters set in the bedrooms during the nighttime, and objective sleep quality was measured by wrist actigraphy.
