Association of Maternal Diet With Zinc, Copper, and Iron Concentrations in Transitional Human Milk Produced by Korean Mothers

The aims of this study were to evaluate zinc, copper, and iron concentrations in the transitory milk of Korean lactating mothers and to investigate the relationship between these concentrations and maternal diet. Human milk samples were collected between 5 and 15 days postpartum from 96 healthy, lactating mothers in postpartum care centers in Seoul, Korea. Dietary intake during lactation was determined based on a 3-day dietary record. The mean zinc, copper, and iron concentrations in the human milk samples collected were 3.88 +/- 1.74 mg/L, 0.69 +/- 0.25 mg/L, and 5.85 +/- 8.53 mg/L, respectively. The mothers who consumed alcoholic beverages during pregnancy had tended to have lower concentrations of zinc and copper, as well as significantly lower concentrations of iron, in their milk (p < 0.047). In contrast, the mothers who took daily supplements had much higher iron concentrations in their milk (p = 0.002). Dietary intakes of zinc, copper, and iron during lactation did not affect the concentrations of zinc, copper, and iron in the milk samples analyzed. Intakes of vitamin C, selenium, and iodine were associated with the concentration of copper in the milk samples analyzed, and consumption of food categorized as 'meat and meat products' was positively associated with the concentration of zinc. Consumption of rice was the top contributor to the concentrations of all three minerals. In conclusion, associations between maternal diet and nutrient concentrations in transitory human milk can provide useful information, particularly in regard to infant growth.

Studies of nutrient composition of transitional human milk and estimated intake of nutrients by breast-fed infants in Korean mothers / 한국영양학회지

PURPOSE: This study was conducted to examine the concentration of nutrients in transitional breast milk from Korean lactating mothers and to evaluate daily intakes of their infants based on the Dietary Reference Intakes for Koreans 2010 (KDRIs 2010). METHODS: Breast milk samples were collected at 5~15 days postpartum from 100 healthy lactating Korean mothers. Macro- and micro-nutrients, and immunoglobulin (Igs) concentrations in breast milk were analyzed. RESULTS: The mean energy, protein, fat, and carbohydrate concentrations in breast milk were 59.99 +/- 8.01 kcal/dL, 1.47 +/- 0.27 g/dL, 2.88 +/- 0.89 g/dL, and 6.72 +/- 0.22 g/dL. The mean linoleic acid (LA), a-linolenic acid (ALA), arachidonic acid (AA), and docosahexaenoic acid (DHA) concentrations were 181.44 +/- 96.41 mg/dL, 28.15 +/- 8.89 mg/dL, 5.67 +/- 1.86 mg/dL, and 5.74 +/- 2.57 mg/dL. The mean vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B2, vitamin B12, and folate concentrations were 2.75 +/- 1.75 microg/dL, 2.31 +/- 1.12 ng/dL, 0.74 +/- 1.54 mg/dL, 3.02 +/- 1.84 mg/dL, 7.51 +/- 20.96 microg/dL, 61.78 +/- 26.78 microg/dL, 63.71 +/- 27.19 ng/dL, and 0.52 +/- 0.26 microg/dL. The mean concentrations of calcium, iron, potassium, sodium, zinc, and copper were 20.71 +/- 3.34 mg/dL, 0.59 +/- 0.86 mg/dL, 66.71 +/- 10.35 mg/dL, 27.72 +/- 10.16 mg/dL, 0.44 +/- 0.41 mg/ dL, and 70.48 +/- 30.41 microg/dL. The mean IgA and total IgE concentrations were 61.85 +/- 31.97 mg/dL and 235.00 +/- 93.00 IU/dL. The estimated daily intakes of infants for protein, vitamin D, vitamin E, vitamin B2, vitamin B12, iron, potassium, sodium, zinc, and copper were sufficient compared to KDRIs 2010 adjusted by transitory milk intakes. The estimated infants' intakes of energy, fat, carbohydrate, vitamin A, vitamin C, vitamin B1, folate, and calcium did not meet KDRIs 2010 adjusted by transitory milk intakes. CONCLUSION: In general most estimated nutrient intakes of Korean breast-fed infants in transitory breast milk were sufficient, however some nutrient intakes were not sufficient based on KDRIs 2010. These results warrant conduct of future studies for investigation of important dietary factors associated with nutrients in breast milk to improve the quality of breast milk, which may contribute to understanding nutrition in early life and promoting growth and development of breast-fed infants.

Treatment of Complete Persistent Sciatic Artery with Distal Thromboembolism by Thromboembolectomy Only

A persistent sciatic artery (PSA) is very rare congenital vascular anomaly which is present in 0.025% to 0.04% of the population by an angiographic study. A PSA is usually combined with aneurismal disease or thromboembolic events because of its arteriosclerosis and vessel wall degeneration. The treatments of symptomatic PSA are comprised of exclusion of PSA from circulation and bypass surgery for the lower limb. However, surgical treatment should be tailored to its anatomy and presentation. We report a successful treatment of PSA with distal thromboembolism by thromboembolectomy without bypass surgery.

An Adult Right-sided Bochdalek Hernia Accompanied with Hepatic Hypoplasia and Inguinal Hernia

We herein report a very rare case of adult right-sided Bochdalek hernia accompanied with hepatic hypoplasia and inguinal hernia. A 29-year-old man was admitted with right-sided pneumothorax. A computed tomography was performed and revealed large right sided Bochdalek hernia with hepatic hypoplasia. Under thoracolaparotomy, the defect was closed with Gore-Tex soft tissue patch. After the operation, left-sided inguinal hernia was found. However, it turned out that it had been present during infancy and spontaneously resolved during adolescence. This is the first report of right-sided Bochdalek hernia with hepatic hypoplasia and inguinal hernia in an adult.

Effect of Diamine Bridges Using L-lysine in Glutaraldehyde Treated Porcine Pericardium / 대한흉부외과학회지

BACKGROUND: Various studies and experimental trials have been done to develop bioprosthetic devices to treat complex congenital heart disease due to the limited usage of homograft tissue. The purpose of the present study was to evaluate the effect of diamine bridges with using L-lysine, as compared with using ethanol. MATERIAL AND METHOD: Porcine pericardium was fixed at 0.625% GA (commercial fixation). An interim step of ethanol (80%; 1 day at room temperature) or L-lysine (0.1 M; 2 days at 37degrees C) was followed by completion of the GA fixation (2 days at 4degrees C and 7 days at room temperature). The tensile strength and thickness of the porcine percardium were measured, respectively. The treated pericardiums were implanted subcutaneously into three-week old Long-Evans rats for 8 weeks. The calcium content of the implants was assessed by atomic absorption spectroscopy and the histology. RESULT: Ethanol pretreatment (13.6+/-10.0 ug/mg, p=0.008), L-lysine pretreatment (15.3+/-1.0 ug/mg, p=0.002), and both treatment (16.1+/-11.1 ug/mg, p=0.012) significantly inhibited calcification, as compared with the controls (51.2+/-8.5 ug/mg). L-lysine pretreatment (0.18+/-0.02 mm, 1.20+/-0.30 kg f/5 mm) significantly increased the thickness and tensile strength, as compared with ethanol pretreatment (0.13+/-0.03 mm, 0.85+/-0.36 1.0 kg f/5 mm) (p<0.01, p=0.035). CONCLUSION: The diamine bridges using L-lysine seemed to decrease the calcification of porcine pericardium fixed with glutaraldehyde, and this was comparable with Ethanol. Additionally, it seemed to enhance the thickness and tensile strength.
