ABSTRACT
A species of predatory nematode, Mylonchulus sigmaturus Cobb, 1917, was recovered around the soil and roots of banana plants (Musa paradisiaca) from four different localities of Pakistan. The male of this species represents a new record from Pakistan. Morphological and morphometric data of the species have been contributed along with the molecular study. The phylogenetic analysis using 18S rDNA placed the Pakistani populations of M. sigmaturus with the same species in a clade with 100 posterior probabilities. The first input of 28S rDNA data placed Pakistani M. sigmaturus in a separate clade with 100 posterior probability support, however close with Prionchulus punctatus (Cobb, 1917) Andrássy, 1958 and Clarkus papillatus (Bastian, 1865) Jairajpuri, 1970.
ABSTRACT
OBJECTIVE: Foetal macrosomia is associated with high maternal and neonatal morbidity; however, obstetric management of suspected macrosomia has not been well defined. This study aimed to analyse obstetric management in a population of women who delivered macrosomic new-borns and assess maternal and neonatal outcomes and risk factors for complications in such cases. STUDY DESIGN: This two-centre retrospective study conducted in France over a 10-year period comprised 1724 women who had delivered macrosomic new-borns (defined as those whose weight was > 90th percentile according to the Association of Users of Computerised Records in Perinatology, Obstetrics, and Gynaecology curve) from 37SA. RESULTS: In this study, the caesarean section and instrumental extraction rates were 24.1% and 15.7%, respectively, and the postpartum haemorrhage rate was 7%. The rate of shoulder dystocia was 23.1% (including brachial plexus injuries, 0.4%; and clavicular fractures, 2.0%). Significant risk factors for caesarean section were maternal height < 160 cm, nulliparity, history of caesarean section, excessive uterine height, induction of labour and duration of labour > 10 h. The risk factors for shoulder dystocia were maternal height < 160 cm and instrumental extraction. CONCLUSION: The study findings may help determine predictive factors for an unfavourable outcome at the time of delivery of a macrosomic foetus, thus allowing clinical teams to better anticipate and manage potential complications.

PURPOSE: To define the effects of attempted external cephalic version (ECV) in a low-risk population for breech delivery in a maternity hospital where breech vaginal delivery is widely practiced. MATERIALS AND METHODS: Retrospective exposed-unexposed study including 204 patients presented with a live singleton fetus breech presentation on third-trimester ultrasound and who delivered at Reims University Hospital between January 1st, 2013 and July 1st, 2018. RESULTS: 121 patients received ECV. Cesarean section rate was lower (OR with no adjustment 0.42 [0.24-0.76] p = 0.004) but without significant difference in the exposed patients after adjustment. This difference was significant between exposed and unexposed patients in the subgroup of 51 primiparous (OR = 0.14 [0.04-0.52] p = 0.002) and 51 multiparous (OR = 0.26 [0.08-0.89] p = 0.028) but not in the subgroup of 102 nulliparous. There was no difference in fetal impact other than neonatal management in the delivery room, which is less needed in exposed primiparous women. Attempted ECV significantly decreased the breech rate (72.5 vs 100%, p < 0.001). There were 7 (5.79%) complications. Three factors favored success: high uterine height (p = 0.011), a non-elevated BMI (p = 0.006) and an earlier term at ECV (p = 0.003). CONCLUSION: The attempt of ECV in the Reims University Hospital does not significantly reduce the Cesarean section rate and has no effect on neonatal status.
