Article Synopsis
  • The study aimed to compare perinatal outcomes and postpartum glucose tolerance between women diagnosed with gestational diabetes before 20 weeks (EGDM) and those diagnosed at or after 24 weeks (LGDM) in Japan.
  • Data from a prospective GDM registry were analyzed, focusing on factors like preterm birth and postpartum glucose intolerance through multivariate analysis.
  • Results showed no major differences in perinatal outcomes between the two groups, but women with EGDM had a higher risk of postpartum glucose intolerance, particularly if they were overweight or obese.

Article Synopsis
  • The study aims to determine if hemoglobin A1c (HbA1c) levels measured early in pregnancy can predict the occurrence of gestational diabetes mellitus (GDM) later in pregnancy.
  • Conducted with 2008 pregnant women, the research used various oral glucose tolerance tests (OGTT) to diagnose GDM and compared the results to the HbA1c levels taken before the 20-week mark.
  • Findings indicated that while HbA1c levels showed some ability to distinguish GDM risk (with an optimal cutoff of 5.4%), it is not considered clinically useful for predicting GDM in mid-pregnancy due to low predictive value.

Article Synopsis
  • The study aimed to examine how obstetric practices in Japan screen and manage early gestational diabetes mellitus (GDM) diagnosed before 20 weeks of pregnancy.
  • A web-based survey was sent to 991 teaching hospitals, yielding a 61% response rate, with most hospitals conducting screening in the first trimester using individual protocols mainly based on random plasma glucose measurements.
  • Findings indicated a strong prevalence of universal screening and treatment for early-GDM, with 94% of hospitals using a 75 g oral glucose tolerance test for diagnosis and 67% providing comprehensive management strategies, including dietary control and insulin if necessary.

To investigate the effects of intentionally minimizing spinal motion and abdominal muscle contractions on intervertebral angles during quadruped upper and lower extremity lift (QULEL). Fifteen healthy men performed the QULEL under four conditions: without any special instructions (basic), with the intention to minimize spinal motion (intentional), with abdominal bracing (bracing), and with abdominal hollowing (hollowing). Each intervertebral angle was calculated from the local coordinate system using the marker data obtained from a motion capture system.

Article Synopsis
  • The study aimed to assess the treatment and outcomes for infants born at 22-23 weeks' gestational age (wkGA) in Japan, using data collected from a national survey in September 2021.
  • Out of 295 Neonatal Intensive Care Units (NICUs), 255 responded, with 145 specifically caring for these premature infants, revealing that a majority actively resuscitated 22 wkGA infants and had high survival rates post-resuscitation.
  • The survey also identified distinct clinical practices in Japan for managing these infants, such as unique delivery methods, immediate medical interventions, and preventive care strategies aimed at improving their outcomes.
