The purpose of this study was to analyze the intake of antioxidant vitamins and plasma TRAP concentrations of 60 maternal-infant pairs (30 in normal term delivery group, NT; 30 in preform group, PT) We also investigated the relationship between plasma TRAP levels of maternal-umbilical cord blood and pregnancy outcomes. Mean energy intakes of NT and PT pregnant women were 93.2% and 85.4% and their protein intakes were 113.3% and 110.9% of the recommended dietary allowance (RDA), respectively. The vitamin A intakes of NT and W pregnant women were 559.7 RE and 497.8 RE, which were less than RDA. While the vitamin E and C intakes of both NT and PT pregnant women were more than RDA. The maternal plasma TRAP level of PT was 1.41 mmol/l and that of was 1.50 mmol/l, which was significantly higher than TRAP level of PT (p < 0.05) . The umblical cord plasma TRAP levels of NT and PT were 1.44 mmol/l and 1.23 mmol/l, which indicates the significant difference between those two groups (p < 0.001) . In case of comparing the TRAP level of maternal and umbilical cord blood, there was no significant difference in NT pregnant women, however, in PT group maternal the TRAP level significant higher than that of umbilical cord (p < 0.001). The length of gestation and plasma TRAP level of maternal and umbilical cord showed a positive correlation. However, other parameters of pregnancy outcomes such as birth weight, weight gain, and Apgar score were not affected by the plasma TRAP levels. Based on these results, preform infants could have a risk of oxidative stress because of low plasma TRAP level.

Anemia diagnosed early in pregnancy is associated with increased risks of low birth weight and preform delivery. The purposes of this study were to assess the maternal iron status during pregnancy and to evaluate the relationships between the iron indices of maternal-umbilical cord serum iron and ferritin levels and pregnancy outcomes. Dietary intakes of the pregnant women were estimated by 24 hour-recall (3 times). Serum iron and ferritin levels in maternal blood and umbilical cord were measured at 1st-, 2nd-, 3rd- trimester and delivery, respectively. The mean of maternal se겨m iron levels of the trimester and delivery were $124.27\;{\mu}g/dl,\;97.03\;{\mu}g/dl,\;94.32\;{\mu}g/dl,\;and\;145.53\;{\mu}g/dl$. Those maternal levels were significantly lower than that of umbilical cord blood ($222.59\;{\mu}g/dl$). Serum ferritin levels of maternal trimester and delivery were 22.68 $22.68\;{\mu}g/l,\;11.09\;{\mu}g/l,\;14.18\;{\mu}g/l,\;and\;\;24.54\;{\mu}g/l$, which were significantly lower than those of umbilical cord blood ($184.35\;{\mu}g/l$) (p < 0.0001). This prevalence of anemia of total subjects was $30.3\%$ by WHO criteria (Hb < 11.0 g/dl, Hct < $33\%$). Iron levels of 2nd-trimester was significantly higher in the normal group than in the anemia group. And ferritin levels of 3rd-trimester and delivery was significantly higher in the normal group than in the anemia group. Therefore, we suggest for successful pregnancy outcome and delivery differential iron supplementation programs will be carried out with individual Pregnant women on the basis of pre-Pregnancy nutrition.

Patients treated with peritoneal dialysis have increased intra-abdominal pressure and a high prevalence of abdominal wall complications. Hernias can lead to significant morbidity in patients on peritoneal dialysis. Hernias are clinically important because of the risk of incarceration, strangulation and subsequent bowel obstruction, rupture, and peritonitis. In this paper, a case of incarcerated umbilical hernia with small bowel obstruction in a continuous ambulatory peritoneal dialysis (CAPD) patient is reported. The small bowel obstruction improved after herniorrhaphy, and the peritoneal dialysis was resumed 2 weeks after the herniorrhaphy. The patient had been undergoing CAPD without technical failure until the 2 months follow-up after the herniorrhaphy. This case shows that early detection of incarcerated umbilical hernia and herniorrhaphy can prevent resection of a strangulated small bowel so that it can remain on CAPD without post-operative technical failure. Umbilical hernias should be carefully observed and intestinal obstruction should be considered when a CAPD patient with an umbilical hernia has abdominal pain.

The purpose of this study was to assess the maternal zinc status during pregnancy and to evaluate the relationship between the zinc concentration of maternal, umblical cord blood and placental tissue and pregnancy outcomes. Venous blood samples were drawn from 53 pregnant women just before delivery and the cord blood of their newborn babies was collected immediately after birth. In addition, placental tissues were extracted. We investigated the difference in the concentration of zinc in maternal, umbilical cord blood and placental tissue in two gestational age groups (preform delivery group [PT] and normal term delivery group [NT]) at 34.7 wk and 39.0 wk of mean gestational age, respectively). We also assessed correlations of the zinc concentration of maternal, umbilical cord blood and placental tissue. Lastly, we studied the correlations between the birth weights and the zinc concentration in the maternal, umbilical cord blood and placental tissue. The concentrations of maternal serum zinc and of umbilical cord serum zinc were significantly higher in the PT group (76.9$\pm$37.4 $\mu/dl$, 101.3$\pm$41.4 $\mu/dl$) than in those of the NT group (57.8$\pm$22.4 $\mu/dl$, 80.7$\pm$27.5 $\mu/dl$), respectively (p<0.05). The zinc concentration of the umbilical cord blood was significantly higher than that of the maternal blood in both groups (p<0.05). There was no significant correlation between the gestational age and the serum zinc concentration in the cord or the maternal serum. Our results showed that there was a negative relationship between the birth weight (r=-0.286) and the maternal serum zinc concentration. Despite there not being a significant difference, there was tendency for the highest concentrations of maternal serum zinc to be associated with the lowest birth weights. These findings support a possible relationship between the maternal zinc status and the pregnancy outcome, and suggest that zinc may play a role in the many biological processes involved in the successful outcome of a pregnancy.

Background Creating a natural-looking umbilicus during closure of the donor-site in abdominally based free flap breast reconstruction is a factor of satisfaction for both the patient and surgeon. We present a simple method of umbilical transposition that results in an aesthetic, natural-looking umbilicus. Methods From March 2011 to November 2014, fifty three consecutive female patients received abdominal flap breast reconstruction. Twenty patients (from March 2011 to February 2013) underwent umbilical transposition through a cross like incision in the abdominal flap, with fascial fixation sutures but no dermal flaps. Thirty three patients (March 2013 to November 2014) received umbilical transposition in the following method. An oval-shaped incision is made at the location of the new umbilicus on the abdominal flap. This oval is deepithelialized, and full-thickness incisions are made at the 2, 6, and 10 o'clock directions to create three triangular dermal flaps. These are pulled down to the abdominal fascia using sutures that pass through the umbilical stalk and the abdominal fascia at the 3, 9, and 12 o'clock directions. This results in an umbilical stalk lined with dermal flaps, creates a natural periumbilical concavity, and anchors the abdominal flap inward to minimize tension. The cranial flap enhances superior hooding. Results Patient and surgeon satisfaction, surveyed 2 months after surgery with a satisfaction scoring system, were higher in the dermal flap group. Conclusions The technique using three dermal flaps in an oval skin incision is simple, relatively easy to learn, and results in an aesthetic, natural-looking umbilicus.

Folate and Vitamin $B_{12}$ are essential nutrients important during pregnancy. This study was conducted to evaluate the folate and vitamin $B_{12}$ nutritional status of Korean pregnant women and to investigate the relationship between maternal­umbilical cord serum folate and vitamin B12 levels and pregnancy outcomes. Dietary intakes of the pregnant women were estimated by 24 hour-recall (3 times). Serum folate and vitamin B12 levels in maternal blood and umbilical cord of 27 pregnant women at 1'st-, 2'nd-, 3'rd-trimester and delivery were measured by RIA (radioimmuno assay), respectively. Means of folate and vitamin $B_{12}$ intake were $283.53\pm58.01{\mu}g/day\;and\; 2.99\pm1.32mg/day$, respectively. Maternal mean serum folate levels of the trimester and delivery were $9.75\pm3.60ng/ml,\;10.46\pm4.63ng/ml,\;10.71\pm4.14ng/ml\;and\;15.05\pm7.04ng/ml$. Those maternal levels were significantly lower than that of umbilical cord blood $(23.99\pm9.42ng/ml)$. Serum vitamin $B_{12}$ levels of maternal trimester and delivery were $479.07\pm137.56 pg/ml,\;310.96\pm137.56pg/ml,\;308.22\pm74.65pg/ml,\;and\;295.67\pm93.36pg/ml$, which were significantly lower than those of umbilical cord blood $(500.13\pm185.60ng/ml)$. This finding indicates that the uptake of folate and vitamin $B_{12}$ in the fetus may be due to an active placental transport mechanism. Maternal serum level correlated positively with those of umbilical cord blood, showing that folate and vitamin $B_{12}$ concentration of umbilical cord blood might be affected by maternal status. There was no significant correlation between the serum folate levels in maternal-umbilical cord blood and the pregnancy outcomes. However, maternal vitamin $B_{12}$ level at l'st trimester was significant positive correlation between the gestational age except for birth weight and weight gain.

The purpose of this study was to evaluate the intake of antioxidant vitamins and plasma concentrations of those in 60 maternal-infant pairs (30 in normal term delivery group, NT; 30 in preform delivery group, PT). We also investigated the relationship between vitamin levels of maternal-umbilical cord plasma and pregnancy outcome. Mean energy intakes of NT and PT pregnant women were 93.2% and 85.4%, and their protein intakes were 113.3% and 110.9% of the recommended dietary allowance (RDA), respectively. While vitamin A intakes were only 51.2% and 39.6% of the RDA in NT and PT pregnant women. The vitamin E intake was about 50% of the RDA (NT 6.27 mg, PT 7.78 mg). The levels of retinol in maternal plasma of NT and PT were $1.51\mumol/\ell\;and\;1.43\mumol/\ell$, respectively. The retinol levels in umbilical cord plasma in NT and PT were $0.72\mumol/\ell\;and\;0.61\mumol/\ell$, respectively. The level of $\beta-carotene$in maternal plasma of NT was 0.49 $\mu$mol/$\ell$, significantly (p ＜ 0.01) higher than that of PT ($0.31\mumol/\ell$).The $\beta-carotene$ of umbilical cord plasma of NT and PT were $0.702\mumol/\ell\;and\;0.01\mumol/\ell$, respectively. The plasma $\alpha$-tocopherol of maternal of NT and PT were $0.72\mumol/\ell\;and\;0.01\mumol/\ell\;29.51 /mumol/\ell\; and 27.17\mumol/\ell,\;respectively.\; The $\alpha$-tocopherol of umbilical cord plasma of NT and PT were $4.16\mumol/\ell\;and\;3.80\mumol/\ell$, respectively. The antioxidant vitamin levels (retinol, $\beta-carotene,\;and\;\alpha$-tocopherol) in maternal plasma were significantly higher (p＜0.0001) than those in umbilical cord plasma. However, there was no correlation between the vitamin levels in maternal plasma and those in umbilical cord plasma. The maternal plasma $\beta$-carotene level showed a positive correlation to gestational age. Also Apgar score at 1 min produced a positive correlation to maternal plasma $\beta$-carotene level.
