OBJECTIVETo investigate the parents' compliance in non-hospital settings during the operation of expressed breast milk bank.

METHODSIn September 2014, a questionnaire survey was carried out to investigate the parents' willingness about feeding the inpatient neonates with maternal expressed breast milk, to evaluate the effectiveness of the breast milk feeding supporting system, and to monitor the compliance in non-hospital settings during the delivery of maternal expressed breast milk. Improvements in education were made according to the results. A second survey was done in September 2015.

RESULTSA total of 340 questionnaires were sent out, and 338 usable questionnaires were returned. According to the time when the questionnaires were sent out, they were divided into two groups: 2014 group (n=229) and 2015 group (n=109). The age of most mothers was 20-30 years in the 2014 group and 30-40 years in the 2015 group. Most mothers delivered at the West China Second Hospital of Sichuan University in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (74.3% vs 61.6%; P<0.05). Guidance was given to mothers in the presence of insufficient breast milk production in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (91.7% vs 79.9%; P<0.05). Both groups had good family compliance in the collection, storage, and transport of breast milk. There were no significant differences in their compliance with washing hands, sterilizing instruments, and using a clean special refrigerator between the two groups. The expressed breast milk was transported strictly according to the procedure in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (100% vs 87.1%; P<0.05).

CONCLUSIONSBefore and after improvements in the health education, most parents have good compliance in the collection, storage, and transport of breast milk.

In big data era, researchers pay more attention to the correlation between biological information of patient samples and related clinical information of diseases. The large volume correlation analysis will help predict the initiation, development and outcome for specific diseases. Disease-related biobank is the core facility bridging the gap between the clinical information and biological information of the disease. The volume, diversity, and especially the quality, and standardization of sample and sample-related information will influence the outcome of big data prediction. Therefore, the establishment of quality management system, and implement of standard inspection and test method are very urgent for continuous improvement of biobanks.

Traditionally, pathologists have used human biological material primarily for diagnostic purposes. More recently, advances in biomedical technology and changes in the research environment have placed new demands on pathologists and their handling of human materials. Moreover, these technological advances have required pathologists to be not only experts in diagnosis, but also managers of biobanks storing human biological material. Consequently, pathologists might now be confronted with unanticipated legal and ethical questions. We investigated seven examples of South Korean legislation concerning human biological material, including "The Bioethics and Safety Act" (2005), and we considered possible conflicts of interest between donors and researchers. We also reviewed international bioethical guidelines and legal precedents from several countries with special regard to pathologic glass slides, paraffin blocks, remaining specimens and other guidelines. We conclude that a better understanding of the legal and ethical questions concerning human biological material leads pathologists to safer and more conscientious management of these samples.

UK Biobank (UKB) is a forward-looking epidemiological project with over 500, 000 people aged 40 to 69, whose image extension project plans to re-invite 100, 000 participants from UKB to perform multimodal brain magnetic resonance imaging. Large-scale multimodal neuroimaging combined with large amounts of phenotypic and genetic data provides great resources to conduct brain health-related research. This article provides an in-depth overview of UKB in the field of neuroimaging. Firstly, neuroimage collection and imaging-derived phenotypes are summarized. Secondly, typical studies of UKB in neuroimaging areas are introduced, which include cardiovascular risk factors, regulatory factors, brain age prediction, normality, successful and morbid brain aging, environmental and genetic factors, cognitive ability and gender. Lastly, the open challenges and future directions of UKB are discussed. This article has the potential to open up a new research field for the prevention and treatment of neurological diseases.

BACKGROUND: Testing for possible microorganism contamination in umbilical cord blood (UCB) is essential for validating the product safety of allogeneic cellular therapeutics. We analyzed the level of contamination and related factors at the largest public cord blood bank in Korea. In addition, we also studied the influence of cryopreservation on contaminating microorganisms. METHODS: UCB was collected, transported, processed, and stored according to standard operating procedures. Microbial detection and identification was performed using a conventional automated blood culture system (BacT/ALERT; bioMerieux, France) with an inoculum of 5-10 mL plasma for pre-freezing UCB. Forty randomly selected non-conforming units were thawed and studied for microbiologic recovery with an inoculum of 2.5 mL. RESULTS: Among a total of 21,236 UCB, 677 (3.19%) were positive for culture. The most frequently identified organism was Lactobacillus spp. (17.2%), followed Bacteroides spp. (10.1%), coagulase negative staphylococcus (6.4%), except the unidentified gram-positive bacillus (21.4%). The contamination rate was higher in vaginal delivery specimens than in cesarean section specimens (4.1% vs. 0.7%, P<0.001), and differed by collection center (0.7-25.4%, P<0.001). Only 55% after-thaw cultures of non-conforming units were positive. CONCLUSION: We determined the contamination rate of UCB in Korea in a large sample size. The results of this study could be used as baseline data at collection centers for quality control purposes. The low recovery rate of microorganisms after cryopreservation presents a possible way to rescue some non-conforming cord blood units, although further study is needed to confirm the reduction of microbiological burden.

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.
