Labour preterm

Brenda F Narice, Nicola H Green, Sheila MacNeil, Dilly Anumba
BACKGROUND: During labour, the cervix undergoes a series of changes to allow the passage of the fetoplacental unit. While this visible transformation is well-described, the underlying and causative microscopic changes, in which collagen plays a major role, are poorly understood and difficult to visualise. Recent studies in mice and humans have shown that Second Harmonic Generation (SHG) microscopy, a non-destructive imaging technique, can detect changes in the cervical collagen. However, the question of whether SHG can identify changes in the arrangement of cervical collagen at different physiological stages still needs addressing...

Monozygotic twins were previously regarded as "identical". By now an increasing number of case reports of monozygotic but discordant twins have been reported, and therefore discordance between monozygotic twins is being investigated intensively. We report a case of female preterm monozygotic twins who were discordant for fetal megacystis due to cloacal dysgenesis. Pregnancy was achieved after intracytoplasmatic sperm injection and transfer of 2 embryos. By the first trimester fetal megacystis with consecutive oligohydramnios and hypoplasia of the lungs was diagnosed...

BACKGROUND & OBJECTIVES: Preterm birth (PTB) is an important cause of prenatal death, neonatal morbidity and mortality and adult illness. Increased inflammation occurs in normal parturition, and inflammatory cytokines and oxidative stress are found to be higher in PTB cases. The present study was planned to investigate the association of organochlorine pesticides (OCPs) with mRNA expression of inflammatory pathway genes such as tumour necrosis factor-alpha (TNF-α) and cyclooxygenase-2 (COX-2) in preterm delivery (PTD) cases...

BACKGROUND: In order to examine the optimal weight gain during pregnancy in Japanese women, we analyzed the perinatal outcomes in Japanese women with the optimal range of weight gain during pregnancy according to the Japanese (the Japanese Ministry of Health, Labour and Welfare: JMHLW and the Japan Society for the Study of Obesity: JASSO) guidelines compared with those according to the USA (the Institute of Medicine: IOM) guideline. METHODS: We compared the obstetric outcomes in two groups of gestational weight gain within the optimal range based on the IOM and Japanese guidelines in women of pre-pregnancy body mass index (BMI) categories of underweight, normal, overweight and obese...

OBJECTIVE: To investigate whether stress, anxiety and depression predict preterm birth in twin pregnancies. METHODS: A prospective cohort study with a convenience sample of women pregnant with dichorionic, diamniotic twins. They were interviewed at 24-28 weeks using the Life Events and Difficulties Schedule and the Hospital Anxiety and Depression Scale. Corticotrophin-releasing hormone, ACTH and cortisol levels were assessed at 28 weeks. The main outcome was premature delivery; there were 42 preterm and 73 term births...

BACKGROUND: To evaluate the neonatal and obstetric outcomes of pregnancies complicated by gestational diabetes mellitus (GDM). Screening and treatment - diet-only versus additional insulin therapy - were based on the 2010 national Dutch guidelines. METHODS: Retrospective study of the electronic medical files of 820 singleton GDM pregnancies treated between January 2011 and September 2014 in a university and non-university hospital. Pregnancy outcomes were compared between regular care treatment regimens -diet-only versus additional insulin therapy- and pregnancy outcomes of the Northern region of the Netherlands served as a reference population...

Female genital mutilation (FGM) is a traditional practice that has no medical benefit and severe health consequences for girls and women. This article discusses the risks to patients who are pregnant and have had FGM. It will describe urinary tract infections caused by FGM, and how this condition increases the risk of preterm labour and delivery. It will also address the difficulty in vaginal examinations that can be caused by FGM and instances when this can delay diagnosis and treatment. In addition, it will explore a number of intrapartum risks caused by FGM and the role of deinfibulation in pregnancy...

This study aims to determine whether the prescription of a detailed lifestyle programme in overweight/obese pregnant women influences the occurrence of gestational diabetes (GDM), and if this kind of prescription increases the adherence to a healthier lifestyle in comparison to standard care. The study was designed as a randomized controlled trial, with open allocation, enrolling women at 9-12 weeks of pregnancy with a BMI ≥ 25 kg/m(2) . The women assigned to the Intervention group (I = 96) received a hypocaloric, low-glycaemic, low-saturated fat diet and physical activity recommendations...

BACKGROUND: Although rare, trauma in pregnancy can cause uterine rupture. In a periviable pregnancy, uterine rupture can lead to premature delivery and significant morbidity. CASE: A 29-year-old woman with four prior CSs presented with uterine rupture and a protruding morbidly adherent placenta at 23+4 weeks of gestation. Since the pregnancy was highly desired, the defect was repaired and the decision made to continue with the pregnancy. The patient presented at 29+3 weeks of gestation with preterm labour and subsequently delivered a healthy male infant of 1130 grams...

Oxidative stress is implicated in the pathophysiology of many reproductive complications including infertility, miscarriage, pre-eclampsia, fetal growth restriction and preterm labour. The presence of excess reactive oxygen species can lead to cellular damage of deoxyribonucleic acids, lipids and proteins. Antioxidants protect cells from peroxidation reactions, limiting cellular damage and helping to maintain cellular membrane integrity. There is overwhelming evidence for oxidative stress causing harm in reproduction...

: Policy statements regarding antenatal consultations for preterm labour are guided by physicians' concerns for upholding the legal doctrine of informed consent, through the provision of standardised homogeneous medical information. This approach, led by classical in-control conceptions of patient autonomy, conceives moral agents as rational, independent, self-sufficient decision-makers. Recent studies on these antenatal consultations have explored patients' perspectives, and these differ from guidelines' suggestions...

OBJECTIVES: In 2006, the Alberta Ministry of Health issued a policy to implement fetal fibronectin (fFN) testing as a publicly funded service for pregnant women. The goals were to reduce maternity health care utilization and unnecessary treatment, which would result in cost-savings for the health system by more accurately diagnosing false preterm labour. We conducted a post-policy implementation review to determine whether the policy implementation achieved its goals. METHODS: We assessed the impacts of fFN testing on clinical decision-making for ambulance transfer, hospital admission, and length of hospital stay by comparing these variables between the tested and untested patients...

Women with diabetes in pregnancy, either pre-gestational Diabetes Mellitus (Type 1 & Type 2) or Gestational Diabetes, are at increased risk for adverse pregnancy outcomes, including preterm labour and increased foetal mortality rate. Adequate glycaemic control before and during pregnancy is crucial for improving foetal and perinatal outcomes in these babies. Perinatal and neonatal morbidities and mortality rates have declined since the development of specialized maternal, foetal, and neonatal care for women with diabetes and their offspring...
