Abstract Background In Japan, as several important vaccines are still categorized voluntary that require out‐of‐pocket payment, the vaccination coverage of is lower than routine vaccines. Thus, higher rates desired. Herein, we used nationwide birth cohort data to create a vaccine risk score identify high‐risk individuals who were not vaccinated with Methods The from 74,733; 73,571; and 74,360 infants analyzed for rotavirus, mumps virus, influenza virus vaccinations, respectively....

Summary This observational cohort study aimed to evaluate the association between duration of neonatal phototherapy and sleep‐and‐wakefulness states at 1 month, 1.5 years, 3 years age. We analysed data from 77,876 infants using Japan Environment Children's Study, a nationwide birth study. The participants were divided into three groups: no phototherapy, short (1–24 h), long (>24 h). Multiple regression analysis was performed assess effect on infant sleep each age after adjusting for...

Polyunsaturated fatty acids (PUFAs) represent a fundamental and essential lipid class, exhibiting versatile biofunctions. Lipidomic analysis has identified growing number of species, including PUFAs with diverse structural variations biofunctions, yet the structure–function relationships are still largely unknown. In this context, there is long-sought demand to synthesize various efficiently. However, no practical methodology exists, unlike case peptides nucleic acids, where molecules...

Objective The postnatal growth of preterm infants is influenced by various factors; however, the association between and long-term outcomes in extremely remains unclear. Therefore, we aimed to determine 6-year development body weight (BW) at 36 weeks corrected age (CA) infants. Study Design We conducted a retrospective observational study including born < 26 gestation. defined key standard deviation score (SDS) using BW birth evaluated BW-related values CA developmental quotient (DQ)....
