STUDY QUESTION: Does proviral integration site for Moloney murine leukemic virus (PIM)1 kinase play a role in regulating the inflammatory processes of human labour and delivery? SUMMARY ANSWER: PIM1 kinase plays a critical role in fetal membranes in regulating pro-inflammatory and pro-labour mediators. WHAT IS KNOWN ALREADY: Infection and inflammation have strong causal links to preterm delivery by stimulating pro-inflammatory cytokines and collagen degrading enzymes, which can lead to rupture of membranes...

BACKGROUND: Respiratory morbidity including respiratory distress syndrome (RDS) is a serious complication of preterm birth and the primary cause of early neonatal mortality and disability. While researching the effects of the steroid dexamethasone on premature parturition in fetal sheep in 1969, Liggins found that there was some inflation of the lungs of lambs born at gestations at which the lungs would be expected to be airless. Liggins and Howie published the first randomised controlled trial in humans in 1972 and many others followed...

Preterm birth (PTB) is the leading cause of perinatal mortality and long-term morbidity, which results in significant health and economic problems. The early detection of PTB has great significance for its prevention. The electrohysterogram (EHG) related to uterine contraction is a noninvasive, real-time, and automatic novel technology which can be used to detect, diagnose, or predict PTB. This paper presents a method for feature extraction and classification of EHG between pregnancy and labour group, based on Hilbert-Huang transform (HHT) and extreme learning machine (ELM)...

OBJECTIVE: in 1997, The Albany Midwifery Practice was established within King's College Hospital NHS Trust in a South East London area of high social disadvantage. The Albany midwives provided continuity of care to around 216 women per year, including those with obstetric, medical or social risk factors. In 2009, the Albany Midwifery Practice was closed in response to concerns about safety, amidst much publicity and controversy. The aim of this evaluation was to examine trends and outcomes for all mothers and babies who received care from the practice from 1997-2009...

BACKGROUND: Strict or partial bed rest in hospital or at home is commonly recommended for women with multiple pregnancy to improve pregnancy outcomes. In order to advise women to rest in bed for any length of time, a policy for clinical practice needs to be supported by reliable evidence and weighed against possible adverse effects resulting from prolonged activity restriction. OBJECTIVES: The objective of this review is to assess the effectiveness of bed rest in hospital or at home to improve perinatal outcomes in women with a multiple pregnancy...

BACKGROUND: Current management of preterm prelabour rupture of the membranes (PPROM) involves either initiating birth soon after PPROM or, alternatively, adopting a 'wait and see' approach (expectant management). It is unclear which strategy is most beneficial for mothers and their babies. This is an update of a Cochrane review published in 2010 (Buchanan 2010). OBJECTIVES: To assess the effect of planned early birth versus expectant management for women with preterm prelabour rupture of the membranes between 24 and 37 weeks' gestation for fetal, infant and maternal well being...

Birth weight is used as a proxy for the general health condition of newborns. Low birth weight leads to adverse events and its effects on child growth are both short- and long-term. Low birth weight babies are more common in twin gestations. The aim of this study was to assess the effects of maternal and socio-demographic risk factors at various quantiles of the birth weight distribution for twin gestations using quantile regression, a robust semi-parametric technique. Birth records of multiple pregnancies from between 1991 and 2005 were identified retrospectively from the birth registry of the Christian Medical College and hospitals in Vellore, India...

BACKGROUND: To reduce the morbidity and mortality associated with preterm birth, home uterine activity monitoring aims for early detection of increased contraction frequency, and early intervention with tocolytic drugs to inhibit labour and prolong pregnancy. However, the effectiveness of such monitoring is disputed. OBJECTIVES: To determine whether home uterine activity monitoring is effective in improving the outcomes for women and their infants considered to be at high risk of preterm birth, when compared with care that does not include home uterine activity monitoring...

Parents and medical staff usually agree on the management of preterm labour at borderline viability, when there is a relatively high risk of long-term neurodevelopmental problems in survivors. If delivery is imminent and parents and staff cannot agree on the best management, however, who should decide what will happen when the baby is delivered? Should the baby be resuscitated? Should intensive care be initiated? Three ethicists, one of whom is also a neonatologist, discuss this complex issue.

BACKGROUND: Cardiotocography (CTG) records changes in the fetal heart rate and their temporal relationship to uterine contractions. The aim is to identify babies who may be short of oxygen (hypoxic) to guide additional assessments of fetal wellbeing, or determine if the baby needs to be delivered by caesarean section or instrumental vaginal birth. This is an update of a review previously published in 2013, 2006 and 2001. OBJECTIVES: To evaluate the effectiveness and safety of continuous cardiotocography when used as a method to monitor fetal wellbeing during labour...

Oxytocin (OT) is a neurohypophysial hormone which has been found to play a central role in the regulation of human parturition. The most established role of oxytocin/oxytocin receptor (OT/OTR) system in human parturition is the initiation of uterine contractions, however, recent evidence have demonstrated that it may have a more complex role including initiation of inflammation, regulation of miRNA expression, as well as mediation of other non-classical oxytocin actions via receptor crosstalk with other G protein-coupled receptors (GPCRs)...
