Abstract We report a case of a monochorionic diamniotic twin with an uncomplicated pregnancy, but with an unexpected large intertwin hemoglobin (Hb) difference at birth. Twin 1 was delivered vaginally and had an uneventful neonatal course. The umbilical cord of Twin 1 was clamped approximately 5 min after birth. After the birth of Twin 1, Twin 2 developed severe bradycardia and showed limited cardiac output on ultrasound, for which an emergency cesarean section was performed. A full blood count revealed an Hb of 20.1 g/dL for Twin 1 and 10.2 g/dL for Twin 2 (intertwin difference 9.9 g/dL). Reticulocyte counts were similar, 40‰ and 38‰, respectively. Placental examination revealed 10 vascular anastomoses, including one arterio-arterial anastomosis with a diameter of 1.4 mm. Additionally, a large chorangioma was present on the placental surface of Twin 2. There was no color difference on the maternal side of the placenta. Based on the reticulocyte count ratio and the placental characteristics, twin anemia polycythemia sequence was ruled out as the cause of the large intertwin Hb difference. In this report, we discuss the various potential causes that could explain the large intertwin Hb difference including the role of delayed cord clamping in Twin 1, and the role of a large chorangioma, which may have attracted blood from the fetal circulation of Twin 2.

Objective As newborns are exposed to oxidative stress during delivery, cord clamping techniques play significant role on antioxidant status. In this study, we aimed to show the relationship between early cord clamping (ECC), delayed cord clamping (DCC) and cut umblical cord milking (C-UCM) techniques with total oxidant capacity (TOC), total antioxidant capacity (TAC) and peroxynitrite levels. Study Design Sixty-nine term infants were selected with APGAR score of 7 and above in the first and fifth minutes. The mothers of all infants had uncomplicated pregnancy, had no congenital anomaly, and delivered by cesarean section. Newborns were randomised to one of three groups: ECC (n: 23), DCC (n: 23) or C-UCM (n: 23). After all newborn babies were taken under radiant heater, blood samples were collected from the umbilical cord. The plasma samples were then frozen and stored at -80 °C until analysis and TOC, TAC and peroxynitrite levels were studied. Results The ages of the mothers participating in the study were between 17 and 42, with an average of 29.14 ± 6.28. 30 (43.5%) of the babies were girls and 39 (56.5%) were boys. The 5th minute APGAR score of the babies in early cord clamping group was significantly lower than the babies in delayed cord clamping and cut cord milking group (p = 0.034; p = 0.034; p <0.05). The TOC, OSI and Peroxynitrite measurements of three groups did not differ statistically. The TAC value of the C-UCM group was significantly higher than the patients with the ECC and DCC group (p = 0.002; p = 0.019; p <0.05). Conclusion C-UCM and DCC would be feasible methods by increasing antioxidant status and providing protective effect on the future health of the term newborns,

Purpose: To assess the association of specific newborn and maternal factors with indicators of increased blood-forming capacity in umbilical cord blood to inform strategic collection strategies that could augment the quality of units in public cord blood banks. Methods: Data regarding 268 consecutive cord blood units (CBUs) banked by Canadian Blood Services were analyzed. Multivariate analysis was performed to identify factors associated with markers of hematopoietic potency and likelihood of utilization. Results: Delayed clamping of the cord beyond 60 s was associated with reduced volume collected. Any delay in clamping of the cord was associated with reduced total nucleated cell counts. Newborn weight >4,000 g was also associated with greater blood volume in the collection but not with other measures of hematopoietic potency. Cord blood acidosis at birth (pH
