This study was done to determine the trans fatty acid (tFA) composition of human milk from postpartum to sixth months after delivery, to investigate the tFA intake of lactating women, and to estimate the intakes of tFA by infants exclusively fed breast milk. A total of 27 lactating Korean women participated to this study voluntarily, gave their breast milk, and responded to an investigation of their diets. The lactating women consumed 2.3-2.8 g/d of tFAs over the period of the first, second, third, and sixth months postpartum, which was 3.4-4.9% of the total fat intake and 0.8%-1.2% of the total energy intake. The proportions of tFAs in the breast milk were 1.89% in colostrum, 1.78% in transitional milk, and 1.78-2.25 in mature milk of the first, second, third, and sixth months postpartum. The tFAs of the breast milk identified in this study were C16:1n9t, C18:1n9t, C18:2n6t12t, C18:2 n6t12c, C18:2n6c12t and C18:2n6t11t. Among them, C18:1n9t was predominant, which made up 59.26% of all tFAs in colostrum, 62.36% in transitional milk, and 64.42% in mature milk. The proportion of total tFA was unchanged with time, although some significant differences were noted for individual tFAs. The percentages of C18:2n6t12c and C18:2n6c12t decreased over the study period. Estimated tFA intake of the exclusively breast-fed infants was 0.18 g/d when fed colostrum, 0.29 g/d when fed transitional milk, and 0.53 g/d when fed mature milk until the sixth month of postpartum. Those were 0.5%, 0.8%, and 1.1% of the total energy intake. The results in this study indicate that lactating Korean women consume not a large quantity of tFAs, secrete breast milk not containing much tFA, and the estimated intake of tFAs by infants fed exclusively breast milk is not great.

Objectives: This study aimed to analyze menu patterns and food group diversity in daycare centers managed by the Center for Children's Foodservice Management in South Korea. Methods: Data from 18 Center for Children's Foodservice Management centers across various provinces (excluding Jeju Island) were analyzed. We examined 8,796 meals served in February, May, August, and December 2021, focusing on seasonal lunch and snack menus for children aged 3-5. Foods were categorized into 19 groups for lunch and 21 for snacks. The frequency of food groups and dietary patterns were assessed using the Dietary Diversity Score. Analyses were conducted using Excel 2016 and IBM SPSS Statistics version 28. Results: Most lunch menus (89%) included five menu items, with a ratio of grain, meat, and vegetables at 88%. Snack menus typically had one item (57%), with significantly more items in the afternoon compared to the morning (P < 0.001). Regarding snack patterns, 75.2% of morning snacks and 61.1% of afternoon snacks contained only one solid food and drink (P < 0.001). Fruit and milk (22.4%) was the most prevalent pattern in morning snacks, while grain and milk (31%) dominated afternoon snacks (P < 0.001). Only 48% of daycare center menus (all snacks and lunch) included all five food groups (grain, meat, vegetables, fruit, and milk). Notably, only 83% included milk and 57% included fruit. Conclusions These findings highlight the need to improve food variety and diversity in the Center for Children’s Foodservice Management-managed daycare center menus.Developing more detailed guidelines for menu structure and food composition is crucial to ensure children receive balanced and diverse nutrition.

PURPOSE: This study was to examine the change of stress and nursing needs in preterm labor women after hospitalization. METHOD: Forty seven women with preterm labor who were admitted in two university hospitals participated in the survey and they were completed the questionnaires on admission day and 5thday after admission. Questionnaires included in modified Antepartum Hospital Stressor Inventory (AHSI) and Nursing Needs for Preterm Labor. The collected data were analyzed by paired t-test and Pearson correlation test. RESULT: The stress level was not decreased significantly after hospitalization. Among them, the stresses about fetus and medical staff were decreased significantly after hospitalization, but those about pregnant women, husband and environment were increased significantly after hospitalization. The difference in the level of nursing needs between the two different days was not significant except the physical needs. The total level of stress and nursing needs were correlated significantly on the 5th day after hospitalization. CONCLUSION: These results indicate that stress and nursing needs of preterm labor women undergo changes after hospitalization. Therefore, development of the program being followed by stressors which change from day to day and further studies are required in order to examine the decreasing of the stress.

OBJECTIVES: This study was conducted to assess the development of posttraumatic stress disorder (PTSD) after occupational physical injuries and the risk factors in occupational accident patients for PTSD. METHODS: Forty-seven occupational accident patients with physical injuries were administered BDI, STAI I and II, SCL-90-R, IES and questionnaires for risk factors and Clinician-Administered PTSD Scale(CAPS). RESULTS: 1) 12 patients(25%) were diagnosed as PTSD. 2) The BDI, STAI I and II and IES scores are significantly high(<0.05) in PTSD group than non-PTSD group. 3) The subscales of SCL-90-R, with an exception of PAR subscale, showed higher scores(<0.05) in PTSD group. 4) The loss of consciousness(LOC) was only significant risk factor in the occupational accident-related factors(<0.05). CONCLUSION: The results of this study show the development of PTSD among occupational accident patients. The loss of consciousness(LOC) was the only signiticant risk factor for PTSD in occupational accident patients.

Purpose: This study aimed to describe the desperate situation where the clinician should make decisions to further manage patients having experienced adverse drug reaction (ADR) to lamotrigine that is indicated to not easily controlled neuropsychiatric diseases. Methods: A descriptive analysis was done by thoroughly reviewing medical records of patients who were reported to have ADR to lamotrigine in a regional drug-safety center between 2010 and 2018. Results: Eighty-four cases of lamotrigine-related ADRs occurred in 80 patients. Skin lesions were most commonly observed in 70 cases (83.3%) and 14 cases (16.7%) had severe ADRs. Sixty-three subjects (78.8%) discontinued lamotrigine, while 17 (21.3%) continued it.At the time of discontinuation, 30.0% were prescribed aromatic antiepileptic drugs. Among 4 subjects who were eventually prescribed lamotrigine again after a period of discontinuation, 3 (75.0%) experienced its recurrence. Among patients who had taken alternative medications, the incidence of ADRs was higher in those being prescribed aromatic antiepileptic drugs than in the others being prescribed other than aromatic antiepileptic drugs (P = 0.013). Regarding the control of underlying diseases, as many as 65 (86.7%) and 68 (90.7%) failed to reach maintaining the resolved state from 6 months and 12 months after the substitution, respectively. Conclusion Patients can be easily trapped between the recurrence of ADRs and the treatment failure to a certain drug like lamotrigine, in which we can hardly find a reasonable alternative to manage them.

Background: The platelet aggregation test is widely used to measure antiplatelet therapy response and to detect platelet function disorders. CS-5100 (Sysmex Co., Japan) is a recently introduced coagulation analyzer that can also measure platelet aggregation. We evaluated the performance of CS-5100 in the platelet aggregation test for use in clinical laboratories. Methods: We investigated the precision, stability, dilution test, and correlation of CS-5100 with a traditional aggregometer. Precision was tested using normal and patient samples. Stability was assessed over 5 different time points for 8 hours. The dilution test was performed with normal samples using ADP agonists. We tested correlations between the results of Chrono-log aggregometer (Chrono-Log Co., USA) and CS-5100 using 10 samples with 5 agonists each. We also calculated the reference range of 5 agonists using 22-30 normal samples. Results: The coefficients of variation using normal samples were 7.45% and 3.27% for ADP and arachidonic acid, respectively. Stability was maintained for up to 2 hours in most samples. Dilution tests showed similar results until reaching a dilution factor of 2. Strong correlations of the results between Chrono-log and CS-5100 were found, except for ristocetin. The reference ranges of 5 reagents in CS-5100 were similar to those obtained with the Chrono-log aggregometer. Conclusions The performance of CS-5100 in platelet aggregation tests showed reliable results compared to a traditional aggregometer. CS-5100 can perform coagulation test and platelet aggregation test, simultaneously. Thus, CS-5100 can enable cost saving and reduce turn-around-time by reducing the inspection time.

PURPOSE: To analyze the isolating pattern of slow cycling cells as putative limbal epithelial stem cells (PLESCs) using Hoechst exclusive cell sorting. METHODS: Rabbits were injected with 5-bromo-2-deoxyuridine (Brd U) 1 month prior to be sacrificed. After obtaining limbal tissues, fluorescence-activated cells were sorted on a Coulter EPICS 753 after they had been incubated with Hoechst 33342 and propidium iodide. Two different methods were applied to sort PLESCs. Side-population(Sp) cells were obtained using gates with dichroic mirror to detect low Hoechst blue and red after verapamil was treated. Hoechst negative cells were obtained using gates exhibiting low Hoechst blue with a 424/44 BP filter. Brd U-retaining cells were counted and their sizes were evaluated in each gated sample to compare isolating pattern of PLESCs in each method. RESULTS: The percentages of Sp cells and of the Hoechst negative fraction were 0.96 +/- 0.79% and 16.01 +/- 13.60%, respectively(p=0.021). Homogeneity and density of the small cells were higher in Hoechst negative fraction than in Sp cells. The percentage of Brd U-retaining cells was 47.36 +/- 10.34% and 47.14 +/- 14.94% in Sp cells and Hoechst negative fraction, respectively(p>0.05), and they were 10 times higher than in non-Sp and Hoechst positive fraction(p=0.000). CONCLUSIONS: Hoechst negative exclusion without verapamil more efficiently isolated PLESCs than Sp did.

PURPOSE: To investigate methods of isolating putative corneal epithelial stem cells from cultured limbal tissue. METHODS: Three extraction techniques were compared to identify an efficient method of obtaining a large number of viable corneal epithelial stem cells from the limbus. Limbal tissues were extracted by incubation at 37 degrees C or 4 degrees C for 1 or 16 hours, respectively, with 1.2U/ml dispase/trypsin or by treatment with 0.05% trypsin and 0.01% ethyldiaminetetraacetic acid (EDTA) at 37 degrees C in single procedure. Collected cells were cultured on NIH/3T3-seeded plates, and colony forming efficiency (CFE) was evaluated. Fluorescence activated cell sorting (FACS) was performed with a Coulter EPICS 753 after incubation with Hoechst 33342 and propidium iodide (PI). Hoechst negative cells were obtained using gates exhibiting low Hoechst blue with a 424/44 nm BP filter. Gated cells of each fraction were re-cultured to assess the capability of colony formation. RESULTS: The mean numbers of viable cells obtained from treatment with dispase and trypsin was 3x10(4) cell/ml and 8.06x10(5) cell/ml at 37 degrees C and 4 degrees C incubations; the number increased to 1.21x10(6) cell/ml with a trypsin/EDTA treatment (p<0.05). CFE was 9.67+/-2.13% and 6.63+/-2.35% in rabbit and human cells, respectively. Likewise, the Hoechst negative fraction was 3.61+/-0.42% and 5.21+/-4.91% in rabbit and human cells, respectively. The sorted Hoechst negative cells were cultured through four passages, forming small round colonies. In rabbit cells, the CFEs of Hoechst negative and positive fractions after FACS, were 12.67+/-2.24% and 1.17+/-6.13%, respectively (p<0.05). CONCLUSIONS: Putative corneal epithelial stem cells were efficiently isolated from limbal tissue using a trypsin/EDTA extraction and FACS. This technique may be very useful in tissue engineered stem cell therapy.

To compare the stem niche in different culture conditions of limbal epithelial cells, the suspended human limbal epithelial cells (HLECs) were seeded on the 3T3-pretreated plates and the other suspended cells were plated on amniotic membranes (AMs) which were either cryo-preserved or freeze-dried. All were cultured for 10 to 12 days. Reverse transcription-polymerase chain reaction (RT-PCR) for ATP-binding casette, subfamily G, member 2 (ABCG2), p63, cytokeratin 12, and connexin 43 were performed in cultivated HLECs and their expression levels were compared. The mRNA expression of all markers examined showed no statistically significant differences between the cells on cryo-preserved and on freeze-dried AM. The expression of p63 and cytokeratin 12 in cultivated cells on AMs were significantly lower than those in 3T3-cocultured cells on RT-PCR and immunofluorescent staining. Cultivated HLECs on AMs showed reduced proliferation and differentiation while maintaining stem-property regardless of the preservative method of AM.

Among hematologic diseases, structural abnormalities of autosomal chromosomes are well-known, but cases involving the sex chromosomes are uncommon. Duplications of the long arm of chromosome 1 have been reported in several hematologic diseases including myelodysplastic syndrome, myeloproliferative neoplasms, acute myeloid leukemia, acute lymphoblastic leukemia, and Burkitt lymphoma. However, dup(1q) as a der(Y)t(Y;1)(q12;q12) is very rare. Here, we report a case of essential thrombocythemia harboring der(Y)t(Y;1)(q12;q12) with literature review.
