AbstractPreterm birth (PTB), defined as the birth of a child before 37 completed weeks gestation, affects approximately 11% of live births and is the leading cause of death in children under 5 years. PTB is a complex disease with multiple risk factors including genetic variation. Much research has aimed to establish the biological mechanisms underlying PTB often through identification of genetic markers for PTB risk. The objective of this review is to present a comprehensive and updated summary of the published data relating to the field of PTB genetics. A literature search in PubMed was conducted and English studies related to PTB genetics were included. Genetic studies have identified genes within inflammatory, immunological, tissue remodeling, endocrine, metabolic, and vascular pathways that may be involved in PTB. However, a substantial proportion of published data have been largely inconclusive and multiple studies had limited power to detect associations. On the contrary, a few large hypothesis-free approaches have identified and replicated multiple novel variants associated with PTB in different cohorts. Overall, attempts to predict PTB using single "-omics" datasets including genomic, transcriptomic, and epigenomic biomarkers have been mostly unsuccessful and have failed to translate to the clinical setting. Integration of data from multiple "-omics" datasets has yielded the most promising results.
The increase of caesarean sections (CS) represents a global concern. Interventions tested to reduce unnecessary caesareans have shown limited success to date, partly because they have focused on medical perspectives or on single faceted interventions targeting only one group of stakeholders. Limited attention has been given to examining multidisciplinary and advocacy activities that could reduce unnecessary CS by raising awareness and engaging the media, advocacy groups, healthcare professionals and politicians. In 2009 in Italy, the national CS rate was the highest in Europe and momentum was building for action. This case study includes a description of the activities conducted in Italy during 2009–2012 by a partnership that included the non-governmental organisation Osservatorio Nazionale sulla Salute della Donna, a bipartisan group of Italian women parliamentarians and the WHO. The objectives were to generate awareness about the increase and overuse of CS in Italy, to foster political actions to reverse this trend, to engage with the media and journalists and to better understand women's birth preferences and needs. A reduction of the CS rate has been observed in Italy following the activities of the initiative from 38.4% in 2009 to 34.2% in 2015 according to the Ministry of Health. Although we cannot infer a casual association between the Partnership and the CS decrease, it did contribute to political momentum and specific actions that should, in theory, have contributed to this reduction. These include the engagement of women parliamentarians for policy change, improved understanding of the local drivers of increases of CS including women's needs and preferences, raising awareness and working with the media to convey appropriate information and an inclusive strategy giving the opportunity to local stakeholders to make their voices heard. This partnership initiative illustrates a model for generating dialogue, reflection and action in countries showing signs of readiness to address escalating CS.

Background: In 2006 WHO presented the infant and child growth charts suggested for universal application. However, major determinants for perinatal outcomes and postnatal growth are laid down during antenatal development. Accordingly, monitoring fetal growth in utero by ultrasonography is important both for clinical and scientific reasons. The currently used fetal growth references are derived mainly from North American and European population and may be inappropriate for international use, given possible variances in the growth rates of fetuses from different ethnic population groups. WHO has, therefore, made it a high priority to establish charts of optimal fetal growth that can be recommended worldwide. Methods: This is a multi-national study for the development of fetal growth standards for international application by assessing fetal growth in populations of different ethnic and geographic backgrounds. The study will select pregnant women of high-middle socioeconomic status with no obvious environmental constraints on growth (adequate nutritional status, non-smoking), and normal pregnancy history with no complications likely to affect fetal growth. The study will be conducted in centres from ten developing and industrialized countries: Argentina, Brazil, Democratic Republic of Congo, Denmark, Egypt, France, Germany, India, Norway, and Thailand. At each centre, 140 pregnant women will be recruited between 8 + 0 and 12 + 6 weeks of gestation. Subsequently, visits for fetal biometry will be scheduled at 14, 18, 24, 28, 32, 36, and 40 weeks (+/− 1 week) to be performed by trained ultrasonographers. The main outcome of the proposed study will be the development of fetal growth standards (either global or population specific) for international applications. Discussion: The data from this study will be incorporated into obstetric practice and national health policies at country level in coordination with the activities presently conducted by WHO to implement the use of the Child Growth Standards. ; publishedVersion

BACKGROUND : A prolonged and complicated second stage of labour is associated with serious perinatal complications. The Odon device is an innovation intended to perform instrumental vaginal delivery presently under development. We present an evaluation of the feasibility and safety of delivery with early prototypes of this device from an early terminated clinical study. METHODS : Hospital-based, multi-phased, open-label, pilot clinical study with no control group in tertiary hospitals in Argentina and South Africa. Multiparous and nulliparous women, with uncomplicated singleton pregnancies, were enrolled during the third trimester of pregnancy. Delivery with Odon device was attempted under non-emergency conditions during the second stage of labour. The feasibility outcome was delivery with the Odon device defined as successful expulsion of the fetal head after one-time application of the device. RESULTS : Of the 49 women enrolled, the Odon device was inserted successfully in 46 (93%), and successful Odon device delivery as defined above was achieved in 35 (71%) women. Vaginal, first and second degree perineal tears occurred in 29 (59%) women. Four women had cervical tears. No third or fourth degree perineal tears were observed. All neonates were born alive and vigorous. No adverse maternal or infant outcomes were observed at 6-weeks follow-up for all dyads, and at 1 year for the first 30 dyads. CONCLUSIONS : Delivery using the Odon device is feasible. Observed genital tears could be due to the device or the process of delivery and assessment bias. Evaluating the effectiveness and safety of the further developed prototype of the BD Odon Device™ will require a randomized-controlled trial.
