Background: Although the benefits of breastfeeding are broadly acknowledged with the efforts of the government and several medical societies, the rate of exclusive breastfeeding through 6 months is lower in Korea than in developed countries.Purpose: This study aimed to investigate pediatricians’ perceptions of breastfeeding barriers and the current breastfeeding counseling environment and propose government policies to encourage breastfeeding in Korea.Methods: Fourteen survey questions were developed during meetings of Korean Society of Breastfeeding Medicine experts. The Korean Pediatric Society emailed a structured questionnaire to domestic pediatricians registered as official members of the Korean Pediatric Society on May 4, 2021, and June 3, 2021. This study examined the survey responses received from 168 pediatricians.Results: The 168 respondents included 62 professors, 53 paid doctors, and 53 private physicians. Breastfeeding was recommended by 146 Korean pediatricians (86.9%). However, only 99 responders (59%) currently provide breastfeeding counseling in hospitals. Most respondents stated providing less than 15 minutes of breastfeeding counseling time in the clinic. Moreover, 89.88% of the respondents responded that they would participate in breastfeeding counseling education if an appropriate breastfeeding counseling program was newly established.Conclusion: This study showed that, although Korean pediatricians had a positive attitude toward breastfeeding, limited counseling was provided for parents. Along with policy support to improve the medical environment through the establishment of an appropriate breastfeeding counseling program, high-quality counseling and an increased breastfeeding rate are expected.

목적: COVID-19 유행은 다양한 사회 문화적 변화를 야기하였지만, 소화기내과 전임의 교육에 대한 영향에 대한 연구는 거의 없었다. 이번 연구에서는 소화기내과 전임의 수련에 대한 COVID-19의 영향에 대해 조사하였다. 대상 및 방법: 2021년 2월 15일부터 3월 15일까지 국내 소화기내과 전임의들에게 온라인 기반 설문조사를 발송하였다. 설문은 소화기내과 전임의의 특성, COVID-19의 유행에 대한 인식도, COVID-19과 비대면 진료의 소화기내과 전임의 교육에 대한 영향에 대한 내용으로 구성되었다. 결과: 111건의 설문 결과들 중 94건의 설문 응답을 분석하였다. 소화기내과 전임의들은 COVID-19 유행에 대해 충분한 정보를 제공받고 있었으며(74.7%), 개인보호장구 착용에 대해 잘 교육받고 있었고, 충분히 제공받고 있었다(각각 74.7% 및 83.9%). 하지만, 외래 진료 스케줄과 환자 수는 각각 25.5%와 37.8%의 응답자들이 감소하였다고 응답하였고, 소화기 내시경 검사 세션과 환자 수도 각각 51.1%와 65.6%의 응답자들이 감소하였다고 응답하였다. 그 결과, 응답자들의 78.9%는 COVID-19의 유행으로 교육에 부정적인 영향을 받았다고 답변하였다. COVID-19 유행 동안에 도입된 비대면 진료가 각각 환자와 의사 측면에서 긍정적인 면이 있다고 답변한 응답자들은 불과 20.0%와 10.6%에 불과하였다. 게다가, 응답자들의 25.9%만이 수가가 적절하게 보상되더라도 비대면 진료를 이용하겠다고 응답하였으며, 68.2%의 응답자들은 비대면 진료가 교육에 부정적인 영향이 있다고 응답하였다. 결론: COVID-19 유행은 외래 진료 감소, 소화기 내시경 검사 감소, 온라인 컨퍼런스, 비대면 진료 도입을 통해 국내 소화기내과 전임의들의 교육에 부정적인 영향이 있었다. COVID-19와 같은 감염병 유행 시에 소화기내과 전임의 교육에 대한 대책 마련이 필요하다. Background/Aims: The coronavirus disease 2019 (COVID-19) outbreak caused numerous social and cultural changes, but few studies focused on their effects on gastroenterology (GI) fellowship training. This study evaluated the impact of COVID-19 on GI fellowship training. Methods: A web-based questionnaire was sent out to GI fellows in Korea between 15 February and 15 March 2021. The questionnaire included questions regarding the characteristics of GI fellows, perception of COVID-19 outbreak, impact of COVID-19 outbreak, and telemedicine on the education of a GI fellowship. Results: Among 111 answers, 94 respondents were analyzed. The GI fellows were provided with sufficient information about the COVID-19 outbreak (74.7%), well educated, and provided with personal protective equipment use (74.7% and 83.9%, respectively). On the other hand, outpatient schedule and volume decreased in 25.5% and 37.8% of respondents, respectively. Moreover, endoscopy sessions and volume decreased in 51.1% and 65.6% of respondents, respectively. As a result, 78.9% of respondents were concerned that the COVID-19 outbreak adversely affected their education. Telemedicine utilization was introduced during the COVID-19 outbreak, but only 20.0% and 10.6% of respondents agreed that telemedicine has benefits from the patient’s and doctor’s perspectives, respectively. In addition, only 25.9% of respondents were willing to continue telemedicine if adequately reimbursed, and 68.2% of respondents were concerned that it adversely affected their education. Conclusions: The COVID-19 outbreak has adversely affected GI fellowship training in Korea for outpatient clinics, gastrointestinal endoscopy, educational conferences, and telemedicine. This study highlights that GI fellowship training needs more attention in the COVID-19 outbreak. (Korean J Gastroenterol 2021;77:205-213)

Won-Ho Hahn,Seong Phil Bae,Hookeun Lee,Jong-Moon Park,Suyeon Park,이주현,강남미 한국분석과학회 2020 분석과학 Vol.33 No.4

Human milk (HM) glycoproteins play important roles protecting infants against various pathogens. Recently, freezing HM is reported to affect some glycoproteins and freeze-drying is suggested as an alternative method. However, the effects of freeze-drying on HM glycoproteins were not evaluated yet. Six fresh HM samples were collected from three healthy mothers at 15 and 60th days of lactation from each mother. Each sample was divided into frozen and freeze-dried subgroups yielding totally 12 samples, and the glycoproteomic analysis was performed by liquid chromatography mass spectrometry. The results were compared between samples of 15 and 60th days of lactation, and before and after the freeze-drying. Totally, 203 glycoproteins were detected. The glycoprotein levels were not different between two groups of 15/60th day of lactation and before/after freeze-drying groups (P > 0.050). In addition, significant correlation of glycoprotein levels was found between the different lactation stages (r = 0.897, P < 0.001) and the status of freeze-drying (r = 0.887, P < 0.001) in a partial correlation analysis. As no significant change of HM glycoproteins was not found after the freezedrying, we hope that introducing freeze-drying to HM banks is supported by the present study. This work was supported by the National Research Foundation (NRF) of Korea grant funded by the Korea government (MSIP) (No.2017R1D1A1B03034270; No.2020R1A2C1005082).

Low Basophil Count and Red Cell Distribution Width at Birth May Predict the Development of Neonatal Necrotizing Enterocolitis: A Matched Control Study

Do-Hyun Kim,Seong-Phil Bae,Won-Ho Hahn,Joon-Hwan Song,Myung-Ho Oh 순천향대학교 순천향의학연구소 2013 Journal of Soonchunhyang Medical Science Vol.19 No.2

Objective: The pathophysiology of necrotizing enterocolitis (NEC) is incompletely understood. There were some reports that the pathogenesis of NEC involves intrauterine process and infants with fulminant NEC had low lymphocyte count. Thus, we investigated complete blood count (CBC) parameters of infants at birth and their mothers near delivery. Methods: We retrospectively reviewed the medical records of NEC patients and controls. The CBC parameters were compared between infants with NEC (modified Bell’s criteria stage ≥Ia, n=82) and controls matched for gestational age, birth weight, gender, and race (n=169). The blood test findings were obtained from infants within the first 2 hours of life and from mothers as the latest one before delivery. Results: Statistically different findings at birth were found in NEC infants; red cell distribution width (RDW) and basophil count. In the multiple logistic regression analysis after adjustment for gestational age, birth weight, and gender, several infantile independent risk factors were identified; basophil count <40/μL (odds ratio [OR], 4.60; 95% confidence interval [CI], 2.18 to 9.73; P<0.001) and low RDW (OR, 7.15; 95% CI, 2.93 to 17.41; P<0.001). Conclusion: We found that NEC was associated with low infantile RDW and basophil count at birth. These findings might support roles of red blood cell and basophil in the pathogenesis of NEC, which might predict development of NEC with neonatal findings at birth.

Kang, Tae Hyuk,Bae, Kwang-Hee,Yu, Min-jung,Kim, Won-Kon,Hwang, Hyang-Ran,Jung, Hyeyun,Lee, Phil Young,Kang, Sunghyun,Yoon, Tae-Sung,Park, Sung Goo,Ryu, Seong Eon,Lee, Sang Chul WILEY-VCH Verlag 2007 Proteomics Vol.7 No.15

<P>Oxidative stress is one of the major causes of neuronal cell death in disorders such as perinatal hypoxia and ischemia. Protein phosphorylation is the most significant PTM of proteins and plays an important role in stress-induced signal transduction. Thus, the analysis of alternative protein phosphorylation states which occur during oxidative stress-induced cell death could provide valuable information regarding cell death. In this study, a reference phosphoproteome map of the mouse hippocampal cell line HT22 was constructed based on 125 spots that were identified by MALDI-TOF or LC-ESI-Q-TOF-MS analysis. In addition, proteins of HT22 cells at various stages of oxidative stress-induced cell death were separated by 2-DE and alterations in phosphoproteins were detected by Pro-Q Diamond staining. A total of 17 spots showing significant quantitative changes and seven newly appearing spots were identified after glutamate treatment. Splicing factor 2, peroxiredoxin 2, S100 calcium binding protein A11, and purine nucleoside phosphorylase were identified as up- or down-regulated proteins. CDC25A, caspase-8, and cyp51 protein appeared during oxidative stress-induced cell death. The data in this study from phosphoproteomic analysis provide a valuable resource for the understanding of HT22 cell death mechanisms mediated by oxidative stress.</P>

<B>Objective</B><P>To investigate whether the presence of autonomic dysfunction is associated with white matter and functional connectivities and the level of cognitive performance in patients with de novo Parkinson disease (PD).</P><B>Methods</B><P>Seventy-five patients with de novo PD underwent a comprehensive autonomic function test and were classified into 2 groups according to the Composite Autonomic Severity Score (CASS; 30 with moderate to severe autonomic dysfunction [CASS 4-10, PD-AUT+] and 45 without significant autonomic dysfunction [CASS 0-3, PD-AUT−]). Network-based statistics and a graph theoretical analysis were performed to assess the interregional white matter connectivity using diffusion tensor imaging. We also performed analyses of resting-state functional connectivity and compared cognitive performance between the 2 groups.</P><B>Results</B><P>There were no significant differences in demographic characteristics and vascular risk factors between the PD-AUT+ and PD-AUT− groups. The PD-AUT+ group showed poorer cognitive performance on frontal/executive function than the PD-AUT− group. The PD-AUT+ group exhibited severely disrupted white matter connectivity in both fronto-subcortical and posterior cortical regions, which was well correlated with the severity of autonomic dysfunction assessed by the CASS. In addition, functional connectivity within the executive control network and dorsal attention network negatively correlated with the CASS.</P><B>Conclusions</B><P>Our results suggest that autonomic dysfunction is associated with disrupted white matter and functional brain connectivity as well as cognitive impairment in de novo patients with PD.</P>

New modified version of the Risk Adjustment for Congenital Heart Surgery category and mortality in premature infants with critical congenital heart disease

Yoon Young Mi,Bae Seong Phil,Kim Yoon-Joo,Kwak Jae Gun,Kim Woong-Han,Song Mi Kyoung,신승한,Kim Ee-Kyung,Kim Han-Suk 대한소아청소년과학회 2020 Clinical and Experimental Pediatrics (CEP) Vol.63 No.10

Background: Despite advances in neonatal intensive care and surgical procedures, perinatal mortality rates for premature infants with congenital heart disease (CHD) remain relatively high.Purpose: We aimed to describe the outcomes of premature infants with critical CHD and identify the risk factors including the new modified version of the Risk Adjustment for Congenital Heart Surgery (M-RACHS) category associated with in-hospital mortality in a Korean tertiary center.Methods: This was a retrospective cohort study of premature infants with critical CHD admitted to the neonatal intensive care unit from January 2005 to December 2016.Results: A total of 78 premature infants were enrolled. The median gestational age (GA) at birth was 34.9 weeks (range, 26.7–36.9 weeks), and the median birth weight was 1.91 kg (range, 0.53–4.38 kg). Surgical or percutaneous intervention was performed in 68 patients with a median GA at birth of 34.7 weeks (range, 26.7–36.8 weeks) and a median birth weight of 1.92 kg (range, 0.53–4.38 kg). The in-hospital survival rate was 76.9% among all enrolled preterm infants and 86.8% among patients who received an intervention. Very low birth weight (VLBW), persistent pulmonary hypertension of the newborn (PPHN), bronchopulmonary dysplasia (BPD), and M-RACHS category 5 or higher (more complex CHD) were independently associated with in-hospital mortality. For the 68 premature infants undergoing cardiac interventions, independent risk factors for mortality were VLBW, BPD, and CHD complexity. Late preterm infant and age at intervention were not associated with patient survival.Conclusion: For premature infants with critical CHD, VLBW, PPHN, BPD, and M-RACHS category ≥5 were risk factors for mortality. A careful approach to surgical intervention and prenatal care should be taken according to CHD type and neonatal condition.

Effect of Pair-Mineralizer on the Reaction of Alite and Calcium Langbeinite Formation

Kwon, Woo Teck,Kim, Young Phil,Kim, Y.,Kim, Soo Ryong,Bae, Seong Youl Trans Tech Publications, Ltd. 2006 Materials science forum Vol.510 No.-

<P>This paper investigates the effect of the pair-minerializer (CaSO4,-CaF2) on the reaction of alite, belite and calcium langbeinite formation with different alkali and sulfate contents. A set of clinker samples was prepared by adding laboratory grade reagents of (NH4)2SO4, CaF2 and K2CO3 to the cement raw mixes. The mineralogical composition of clinker was analyzed by X-ray powder diffraction, and the quantity of minerals was evaluated by using TOPAS software. As the experimental results, the total amount of calcium silicate minerals was rapidly increased with the addition of F and SO3 components simultaneously as pair-mineralizer with K2O more than the value which mineralizer was added separately. Also, in the case of adding K2O only to the raw mixes, the amount of alite is decreased after clinkering. However, if alkali (K2O) and pair-minerializer (CaSO4,-CaF2) were added simultaneously, the quantity of alite and calcium langbeinite mineral increased because of the formation of stable clinker minerals by the reaction of alkali (K2O) and sulfate.</P>
