Short-term outcomes in early term infants (born at 37 or 38 weeks): a retrospective investigation.

Introduction: Recently, researchers have introduced the concept of 'early term' infants, defined as infants born at 37 or 38 weeks of gestation, and their outcome has been discussed. Although the complications experienced by early term are less severe than those in preterm infants, this group accounts for a much larger proportion of newborns, making the assessment of outcomes important in clinical practice.

Methods: This observational study of term infants born at Tokyo Metropolitan Toshima Hospital aimed to understand the short-term outcomes in early term infants.

Maternal Protein Restriction Inhibits Insulin Signaling and Insulin Resistance in the Skeletal Muscle of Young Adult Rats.

Objectives: Infants with fetal growth restriction (FGR) are at a risk of developing metabolic syndromes in adulthood. We hypothesized that skeletal muscle degeneration by nutrition-restricted FGR results in abnormal insulin signaling and epigenetic changes.

Material And Methods: To develop a protein-restricted FGR model, rats were fed a low-protein diet (7% protein) during the gestational period; rats fed a normal diet (20% protein) were used as controls.

Clinical Features of RS Virus Infection before, during, and after COVID-19 Pandemic.

The COVID-19 pandemic has impacted the epidemiology of other infectious diseases. In particular, the respiratory syncytial (RS) virus infects almost all children during their first or second year of life. However, during the COVID-19 pandemic, many restrictions were enforced that isolated children from other children.

Body Mass Index Changes at 1.5 and 3 Years of Age Affect Adult Body Composition.

Early childhood lays the foundation for many outcomes in later life. Recent studies suggest that early childhood development may contribute to lifestyle-related diseases such as obesity, type 2 diabetes, and cardiovascular disease in adulthood; however, there have been few investigations on this association among adults in Japan. Therefore, we examined the relationship between recent physical measurements in adults who underwent health checkups at our university and their physical measurements at birth and during infancy recorded in the Maternal and Child Health Handbook.

Holiday effect on childbirth: A population-based analysis of 21,869,652 birth records, 1979-2018.

Maternity and neonatal services always have to operate 24 hours a day and 7 days a week, and require well preparedness to guarantee safe deliveries for both mothers and babies. However, the evidence of holiday effect from large-scale data is still insufficient from the obstetrics perspective. We analyzed data of over 21 million births in Japan from January 1, 1979, to December 31, 2018.
