Research paper thumbnail of 597: Maternal obesity drives perinatal outcome differences more than racial disparities

Adjusted risk factors for a uterine rupture were an interval between the previous cesarean and delivery <21 months, birthweight >4000g, oxytocin use during labor, induction of labor, a Bishop score <6 at admission in the delivery room and failure to progress !2h. A one layer suture to repair the previous cesarean hysterotomy was not a risk factor of uterine rupture but 50% of data were missing. CONCLUSION: The rate of uterine rupture during TOLAC was low in France, on the same order as in North American studies despite different obstetrical practices. The main risk factors for uterine rupture were a short interdelivery interval, as well as labor induction and augmentation. Risks factor of uterine rupture in cases of TOLAC Data were missing for less than 5% for all factors except for closure of previous hysterotomy (51%). *Model 1: aOR adjusted for age, geographic origin, previous vaginal birth, previous preterm cesarean, interval between previous cesarean and delivery; **Model 2: model 1 + birthweight.

The objective of this study is to examine the effect of melatonin on clinical, biochemical, neurophysiological and radiological outcomes of neonates with hypoxic-ischemic encephalopathy (HIE). We conducted a prospective trial on 45 newborns, 30 with HIE and 15 healthy controls. HIE infants were randomized into: hypothermia group (N=15; received 72-h whole-body cooling) and melatonin/hypothermia group (N=15; received hypothermia and five daily enteral doses of melatonin 10 mg kg(-1)). Serum melatonin, plasma superoxide dismutase (SOD) and serum nitric oxide (NO) were measured at enrollment for all infants (N=45) and at 5 days for the HIE groups (N=30). In addition to electroencephalography (EEG) at enrollment, all surviving HIE infants were studied with brain magnetic resonance imaging (MRI) and repeated EEG at 2 weeks of life. Neurologic evaluations and Denver Developmental Screening Test II were performed at 6 months. Compared with healthy neonates, the two HIE groups had increased melatonin, SOD and NO. At enrollment, the two HIE groups did not differ in clinical, laboratory or EEG findings. At 5 days, the melatonin/hypothermia group had greater increase in melatonin (P&amp;amp;amp;amp;amp;amp;lt;0.001) and decline in NO (P&amp;amp;amp;amp;amp;amp;lt;0.001), but less decline in SOD (P=0.004). The melatonin/hypothermia group had fewer seizures on follow-up EEG and less white matter abnormalities on MRI. At 6 months, the melatonin/hypothermia group had improved survival without neurological or developmental abnormalities (P&amp;amp;amp;amp;amp;amp;lt;0.001). Early administration of melatonin to asphyxiated term neonates is feasible and may ameliorate brain injury.

This study explored metacognitve listening strategies awareness and its relationship with listening comprehension on a convient sample of 386 tenth-grade EFL learners using two instruments: (a) Metacognition Awareness Listening Questionnaire (MALQ) and (b) a Listening Comprehension Test (LCT) developed by the researchers for the purpose of this study. The results indicate that students' possess a moderate level of metacognitive listening strategies awareness. Additionally, whereas directed attention and personal knowledge fail to explain the variance in students' listening comprehension performance, problem solving, planning and evaluation, and directed attention are capable of explaining 56% of the variance in students' performance on the LCT. It is recommended that metacognitive strategies awreness be emphasized in listening comprehension instruction.

However, learning obstacles have not been widely researched in the field of language learning strategies. This study explores the difficulties or barriers confronted by the EFL (English as a Foreign Language) learners while acquiring listening comprehension strategies during a training program. The findings indicate that the obstacles confronted by the learners are multifaceted. Each facet carries a probable risk of comprehension failure. Learning barriers are associated with the internal factors of learners such as their affective statuses, listening habits, information processing capacities, English proficiencies, and their belief about listening activities. Other barriers concerned the nature of listening strategies and the listening material used. Based on the findings, a series of pedagogical implications are provided.
