RESUMEN
INTRODUCTION: Cardiotocography (CTG) has its limits in detecting fetal acidosis and intrapartum asphyxia. Our aim was to evaluate a CTG training programme based on fetal physiology in the Mediterranean perinatal network. METHODS: Professionals from 41 maternity units of the Mediterranean network were invited to participate in a CTG masterclass based on fetal physiology in March 2019 and October 2019. They were asked to react to three practical cases by a physiological approach before the training course (T0), one month after (T1) and six to seven months after (T2). The mean scores were compared by using a mixed model including lapse of time to evaluation, profession of participants and level of the maternity unit as fixed effects. RESULTS: A total of 248 professionals from 32 maternity units finally participated in the organizational audit. By using a mixed model, we found a significant improvement of the mean score at T1=6.44/10 compared to T0=4.97/10 (p<0.0001), and a significant improvement of the mean score obtained at T2=6.17/10 compared to T0 (p<0.0001). T2 scores were not significantly different from T1 scores (p=0.143). DISCUSSION: A CTG training programme based on fetal physiology showed a significant improvement in the professionals' interpretation of CTG at short term and stable results at long term. Continuing medical education could help maintain and improve knowledge to ensure neonatal safety.

OBJECTIVE: This study was aimed at assessing the role of leptin on human myometrium, by studying its receptor expression in pregnant myometrium and the interaction of leptin with inflammation-induced apoptosis. STUDY DESIGN: Myometrial samples were obtained from women with uncomplicated pregnancies who underwent cesarean delivery at term before labor onset. The effect of leptin on apoptosis was assessed by the incubation of myometrial strips with leptin (10(-10) to 10(-8) mol/L; 48 hours) before lipopolysaccharide treatment (10 µg/mL; 48 hours). RESULTS: Long and short leptin receptor isoforms were expressed in myometrial cells of pregnant women. Leptin prevented lipopolysaccharide-induced apoptosis, in a concentration-dependent manner, by down-regulating cleaved caspase-3 and BCL2-associated X protein and up-regulating BCL2 expression. This effect was mediated specifically through leptin receptor stimulation, followed by ERK1/2 signaling pathway activation. CONCLUSION: These results suggest a new potential pathway that is involved in delivery disorders of obese women and propose a role for the leptin-induced inhibition of myometrial apoptosis in the development of such disorders.

The obstetrician is more and more frequently faced with the decision to perform a cesarean section in obese women. We describe a technique of supra or subumbilical transverse cesarean section (depending on the height of the projection of the upper edge of the pubic symphysis) specifically designed for morbidly obese women with a voluminous panniculus. We evaluated feasibility and associated morbidity in a retrospective descriptive series of 18 patients operated between 2003 and 2008. We assessed the quality of access to the lower uterine segment and facility to extract the fetus. The mean body mass index was 47.7 kg/m(2) (range 40.1-60.8). The incision was subumbilical in 13 women (72.2%) and supraumbilical in 27.7%. With this technique, the exposition, the section of the lower uterine segment, and extraction of the baby are simple. It can be easily generalized and quickly learnt.
