Our intermittent KMC was a safe and feasible method for preterm infants. Notably, at the same PMA, preterm infants in the lower at-birth GA group showed an advanced maturation of thermoregulation compared with those in the higher GA group.
BackgroundAlthough bone marrow (BM) or mobilized peripheral blood (PB) is frequently used as the source of hematopoietic stem cells, hematopoietic stem cell transplantation (HSCT) using cord blood (CB) is gradually gaining popularity in many countries. However, BM or PB is still preferred over CB in Korea. Therefore, we tried to assess the awareness of CB transplantation (CBT) among domestic HSCT physicians and develop strategies for boosting its utilization by administering questionnaires to some of these physicians.MethodsA direct questionnaire survey was conducted using the "Audience Response System" among 301 members who attended the annual meeting of the Korean Society of Blood and Marrow Transplantation. The data were analyzed for only 67 board certified physicians who were directly involved in HSCT activities.ResultsThe poor outcomes resulting from insufficient experience in CBT was designated by the physicians as the main reason for the low domestic implementation of HSCT using CB. Other reasons identified in the survey were distrust in the quality and management of domestic CB and the high cost of obtaining CB.ConclusionIncreasing the use of donated CB would foremost require increasing the inventory of donated CB containing a sufficient cell number for CBT and securing structured quality control of the CB banks. In addition, it would be necessary to minimize CB supply costs and continue to provide academic data, including CBT guidelines, so that clinicians could perform CBT with more confidence.
Purpose: In the present study, we aimed to determine the risk factors for the development of cystic periventricular leukomalacia (CPVL) in very low birth weight (VLBW) infants. Methods: We reviewed the medical records of 309 infants weighing less than 1,500 g who were admitted to the neonatal intensive care unit at Hanyang University Medical Center, Seoul from April 2007 to December 2012. Thirty-nine infants died within 28 days of birth. Of the remaining 270 infants, 21 with CPVL established by cranial ultrasonography, and 63 without CPVL, who were matched for gestational age, were enrolled in this study. Univariate and multivariate analyses of maternal, perinatal, and neonatal risk factors for CPVL were performed through retrospective assessment of data collected from the medical records. Results: Necrotizing enterocolitis (NEC ≥stage II: 42.9% vs. 9.5%, P=0.002), cultureproven sepsis (66.7% vs. 34.9%, P=0.021), hypotension with sepsis (33.3% vs. 6.3%, P=0.004), and severe intraventricular hemorrhage (≥grade III: 61.9% vs. 22.2%, P= 0.002) were associated with the development of CPVL on univariate analysis. Using multivariate logistic regression analysis, two variables were found to be statistically significant independent risk factors: NEC (≥stage II: adjusted OR, 5.12; 95% CI, 1.219-21.514; P=0.026) and hypotension with sepsis (adjusted OR, 8.23; 95% CI, P=0.032). Conclusion: NEC (≥stage II) and hypotension with sepsis were associated with an increased risk of developing CPVL in VLBW infants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
