Background: Both fish-oil lipid injectable emulsion (FO-ILE) and mixed-oil lipid injectable emulsion (MO-ILE) are key components of parenteral nutrition and require importation into Japan, and they are easily oxidized after opening. Given the small daily volumes of these lipids dispensed in infants and children with intestinal failure (IF), the purpose of the study was to identify the optimal storage method.

Methods: Lipids were prepared in polypropylene syringes in the following manner: air-sealing and photoprotection, air-sealing only, photoprotection only, and uncovered.

Article Synopsis
  • - The study compares anemia cases in infants with gastroschisis and omphalocele, analyzing data from 60 patients across five pediatric surgery departments in southern Japan from 2011 to 2020.
  • - Results indicated that infants with gastroschisis received more iron treatment during hospitalization but had lower hemoglobin levels at their first outpatient visit compared to those with omphalocele, highlighting significant risk factors for anemia related to gastroschisis and gestational age at birth.
  • - The findings suggest that infants with gastroschisis are at a higher risk of anemia, potentially due to their unique exposure to amniotic fluid and the impact it has on their intestinal health in utero.

Introduction: We aimed to evaluate the risk factors for mortality and neurodevelopmental impairment (NDI) among infants of 22-23 weeks' gestational age, which currently remain unclear.

Methods: This retrospective case-control study included 104 infants delivered at 22-23 weeks' gestation at Kagoshima City Hospital from 2006 to 2015. We compared 65 and 34 cases of survival to discharge and postnatal in-hospital death (5 excluded), respectively, and 26 and 35 cases with and without NDI, respectively, using maternal, prenatal, and postnatal records.

Article Synopsis
  • The study evaluates the use of loop-mediated isothermal amplification (LAMP) for rapid detection of Ureaplasma spp. in respiratory samples from preterm infants, comparing it to traditional methods like culture and quantitative real-time PCR.
  • Conducted at Kagoshima City Hospital from June 2018 to March 2020, the research included 167 nasopharyngeal swabs and 101 tracheal aspirates from infants born before 32 weeks of gestation.
  • LAMP demonstrated comparable sensitivity and specificity to quantitative real-time PCR, making it a viable alternative for early diagnosis and timely antibiotic treatment to prevent bronchopulmonary dysplasia (BPD).

Coronavirus disease 2019 (COVID-19) has spread worldwide within a short period, and there is still no sign of an end to the pandemic. Management of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected pregnant women at the time of delivery presents a unique challenge. To fulfill the goal of providing adequate management of such women and their infants, and to decrease the risk of exposure of the healthcare providers, tentative guidelines are needed until more evidence is collected.

The Japan Resuscitation Council joined the International Liaison Committee on Resuscitation (ILCOR) as a member of the Resuscitation Council of Asia in 2006. In 2007, the Japan Society of Perinatal and Neonatal Medicine (JSPNM), which is a member of an affiliated body, launched the Neonatal Cardiopulmonary Resuscitation (NCPR) program as an authorized project to ensure that all staff involved in perinatal and neonatal medicine can learn and practice neonatal cardiopulmonary resuscitation based on the Consensus on Science with Treatment Recommendations developed by ILCOR. The content of courses in the NCPR program is based on the NCPR guidelines.

In July 2007, the Neonatal Cardiopulmonary Resuscitation (NCPR) program in Japan was launched to ensure that all staff involved in perinatal and neonatal medicine can learn and practice NCPR based on the Consensus on Science with Treatment Recommendations developed by the International Liaison Committee on Resuscitation. In 1978 in North America, a working group on pediatric resuscitation was formed by the American Heart Association Emergency Cardiac Care Committee and concluded that the resuscitation of newborns required a different strategy than the resuscitation of adults. The original first edition of the Neonatal Resuscitation Program textbook was published in 1987.
