This study revealed that an injection of adipose-derived MSCs loaded in fibrin glue during rotator cuff repair could significantly improve structural outcomes in terms of the retear rate. There were, however, no clinical differences in the 28-month period of follow-up. Although still in the early stages of application, MSC augmentation of surgical rotator cuff repair appears useful for providing an adequate biological environment around the repair site.
Human milk banks are a solution for mothers who cannot supply their own breast milk to their sick or hospitalized infants; premature infants, in particular, are unable to receive a full volume of breast milk for numerous reasons. As of December 2015, there was only one milk bank in a university hospital in Korea. We reviewed the basic characteristics of donors and recipients, and the amounts and contamination of breast milk donated at the Human Milk Bank in Kyung Hee University Hospital at Gangdong in Korea from 2008 to 2015. The donor pool consisted of 463 first-time donors and 452 repeat donors who made 1,724 donations. A total of 10,820 L of breast milk was collected, and 9,541.6 L were processed. Detectable bacteria grew in 12.6% after pasteurization and 52.5% had cytomegalovirus DNA before pasteurization in donated milk. There were 836 infant and 25 adult recipients; among new infant recipients, 48.5% were preterm; the groups received 8,009 and 165.7 L of donor milk, respectively. There was an increase in the percentage of preterm infants among new infant recipients in 2015 (93.1%) compared to 2008 (8.5%). Based on the number of premature infants in Korea, the number of potential recipients is not likely to diminish anytime soon, despite efforts to improve the breastfeeding rate. Sustainability and quality improvement of the milk bank need long-term financial support by health authorities and a nationwide network similar to blood banking will further contribute to the progress of milk banking.
Breastfeeding has numerous benefits both for infants and mothers. WHO, UNICEF, and OECD report the breastfeeding rate (BR) and exclusive breastfeeding rate (EBR) at 3, 4, and 6 months of age for the international comparison. This article investigates the nationwide changes in BR and EBR in Korea from 1994 to 2012. EBR declined from 1994 to 2000, however progressively increased untill 2012. The latest data in 2012 revealed EBRs at 3, 4, and 6 months were 50.0%, 40.5%, and 11.4% respectively. The exclusive formula feeding rate (EFR) was highest in 2000 and gradually declined thereafter. In 2012, the EFRs at 3, 4 and 6 months were 21.7%, 26.5%, and 10.1%. In 2009, the EBRs at 3 and 6 months in the United States were 36.0% and 16.3% compared to 50.0% and 11.4% in Korea. In England, the EBRs were 17% and 12% in 2010. Amongst OECD countries, Hungary ranked highest EBRwith 95%, and Iceland, Norway, Slovak Republic, Australia, New Zealand followed. In conclusion, BRs were lowest in 2000, and there have been remarkable increases in BRs over the past 10 yr in Korea. Although BRs have been increasing, further efforts to increase BRs should be made continuously.
Neonatal mortality rate (NMR) and infant mortality rate (IMR) are two of the most important indices reflecting the level of public health of a country. In this review, we investigated changes in NMR and IMR in Korea and compared the results with those of Japan, USA, and OECD nations. During the past 20 yr, NMR and IMR have lowered remarkably from 6.6 and 9.9 in 1993 to 1.7 and 3.2 in 2009, respectively, in Korea. It is an impressive finding that Korean IMR (3.2 in 2009) is lower than the average of OECD nations (4.7 in 2008), and USA (6.3 in 2009), although higher than Japanese IMR (2.8 in 2009). The proportion of NMR among the IMR calculation decreased from 66.7% in 1993 to 53.1% in 2009. The reason the value of Korea was higher than Japan but lower than USA was speculated to be an aspect of the health care service system. Several suggestions in perinatal, neonatal and infantile health care such as establishment of perinatal care center, research network system, regionalization, and new policies for care of pre-term and high risk pregnancy, are elucidated to achieve further improvement on NMR and IMR in Korea.
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.
