Labour preterm

BACKGROUND: Despite recent advances in medicine, the incidence of pre-term birth is increasing globally. Approximately 70% of neonatal deaths, 36% of infant deaths, and 25-50% of cases of neurological impairment in children can be attributed to pre-term births. Identification of risk factors in women, supervised obstetric care during pregnancy, female empowerment, and patient education are strategies to minimize the burden of preterm deliveries. MATERIALS AND METHODS: A prospective cross-sectional study was conducted over a 1-year period among 658 women in the Department of Obstetrics and Gynecology, Pramukhswami Medical College, Anand, Gujarat...

BACKGROUND: Midwives are primary providers of care for childbearing women globally and there is a need to establish whether there are differences in effectiveness between midwife continuity of care models and other models of care. This is an update of a review published in 2016. OBJECTIVES: To compare the effects of midwife continuity of care models with other models of care for childbearing women and their infants. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Trials Register, ClinicalTrials...

OBJECTIVE: To determine the various causes and factors leading to preterm birth in women presenting at tertiary care hospitals. METHODS: The cross-sectional, prospective study was conducted from June 19, 2021, to January 19, 2022, at the Central Park Teaching Hospital, Lahore, Pakistan, in collaboration with other tertiary care teaching hospitals in Lahore, and comprised pregnant women aged 15-45 years with preterm birth. Demographic and obstetric data was collected...

OBJECTIVE: If a small for gestational age (SGA) foetus needs to be delivered because of severity (< 3rd centile) attempting induction of labor theoretically increases the risk of caesarean section and neonatal acidosis, but these risks are poorly understood. This article aims to assess the risk of caesarean section and neonatal acidosis in attempted vaginal birth of a moderately preterm foetus in the setting of severe SGA. METHOD: A single-centre hospital-based observational study conducted over a period of 17 consecutive years in mothers with a single foetus in cephalic presentation with severe SGA (< 3rd centile) needing foetal extraction...

BACKGROUND AND OBJECTIVES: No previous study has been conducted in Nigeria on the role of neutrophil elastase in predicting preterm birth. The present study aimed to determine the role of the neutrophil elastase test in predicting birth in women with preterm labor. METHODS: The present prospective cohort study recruited 83 pregnant women with preterm labor between 28 and 36+6 weeks of gestation, and followed up these subjects for 14 days. The controls comprised 85 pregnant women without preterm labor...

Background : The objective was to assess the association between early HbA1c levels and pregnancy complications and whether this relationship is affected when HbA1c thresholds are greater than or less than 39 mmol/mol (5.7%). Methods : Electronic searches of the MEDLINE and EMBASE databases up to October 2022 were conducted. We included retrospective and prospective observational studies. The inclusion criteria were as follows: HbA1c measurements taken at <20 weeks' gestation, singleton pregnancy, and no pre-existing diabetes mellitus...

Deferred cord clamping (DCC) has been associated with reduced mortality in preterm infants, and a period of at least 30 s has been recommended before clamping. However, preterm infants assessed as being in need of resuscitation have often had earlier cord clamping. In this study, we aimed to compare neonatal outcomes for preterm infants undergoing DCC who established early breathing movements compared to those who were not breathing. After a 5 yr recruitment period, we recently completed the ABC study, in which preterm infants <31 weeks undergoing 50 s of DCC who were not breathing by 15 s of age were randomised into two groups: one received intermittent positive pressure ventilation (IPPV) and the other was a standard group, which received no breathing support...

BACKGROUND: The aim of this study is to identify risk factors associated with histological chorioamnionitis (HCA) and develop a predictive model for antepartum assessment of the risk of PPROM with HCA. METHODS: This study retrospectively analyzed pregnant women who experienced PPROM between 25 + 0 and 35 + 0 weeks of gestational age. The women were divided into two groups based on the presence or absence of HCA. Univariate and multivariate logistic regression analyses were conducted to identify maternal risk factors and develop a clinical prediction model for HCA...

OBJECTIVE: To compare the effectiveness of cervical pessary and vaginal progesterone in the prevention of adverse perinatal outcomes and preterm birth in pregnant women of singletons with no prior spontaneous preterm birth at less than 34 weeks' gestation and who have a short cervix of 35 mm or less. DESIGN: Open label, multicentre, randomised, controlled trial. SETTING: 20 hospitals and five obstetric ultrasound practices in the Netherlands...

Vitamin D deficiency increases the risk of adverse pregnancy outcomes. The high prevalence of vitamin D deficiency worldwide requires the analysis of scientific publications to make recommendations for the prevention, management and treatment of vitamin D deficiency in pregnant women. The purpose of the research was to explore the relationship between pathology and pregnancy outcomes with serum 25-hydroxycholecalciferol levels and vitamin D supplementation. A literature search was performed for systematic literature reviews with meta-analyses published between January 2018 and February 2023...

BACKGROUND: A substantial number of women who subsequently become pregnant and give birth have a history of physical, sexual, and/or child abuse. This study investigated the associations of these types of traumas and their cumulative effect with childbirth experiences, namely, mode of birth, maternal and child complications during pregnancy/childbirth, preterm birth, medical procedures, and obstetric violence during labour. METHODS: A group of Russian women (n = 2,575) who gave birth within the previous 12 months, completed a web-based survey, where they provided demographic information, details about their childbirth experiences, and a history of trauma...

INTRODUCTION: Pre-eclampsia affects ~5%-7% of pregnancies. Although improved obstetric care has significantly diminished its associated maternal mortality, it remains a leading cause of maternal morbidity and mortality in the world. Term pre-eclampsia accounts for 70% of all cases and a large proportion of maternal-fetal morbidity related to this condition. Unlike in preterm pre-eclampsia, the prediction and prevention of term pre-eclampsia remain unsolved. Previously proposed approaches are based on combined third-trimester screening and/or prophylactic drugs, but these policies are unlikely to be widely implementable in many world settings...

BACKGROUND: An increased risk of preterm birth has been observed among individuals with a previous second stage cesarean delivery compared with a previous vaginal delivery. One mechanism that may contribute to the increased risk of preterm birth following second stage cesarean delivery is the increased risk of cervical injury due to extension of the uterine incision (hysterotomy) into the cervix. Investigating the contribution of hysterotomy extension to the rate of preterm birth has not been well-studied and may shed light on the mechanisms underlying the observed relationship between mode of delivery and subsequent preterm birth...

OBJECTIVE: We conducted a systematic review and meta-analysis to examine the relationship between stillbirth and various perinatal outcomes in subsequent pregnancy. DATA SOURCES: PubMed, the Cochrane Library, Embase, Web of Science, and CNKI databases were searched up to July 2023. STUDY ELIGIBILITY CRITERIA: Cohort studies that reported the association between stillbirth and perinatal outcomes in subsequent pregnancies were included...

OBJECTIVE: We aimed to determine the association between polycystic ovarian syndrome (PCOS) and cervical incompetence (CI). We hypothesise that insulin resistance induces a glucose metabolism disorder that could potentially cause cervical incompetence, resulting in an adverse outcome. DESIGN: We conducted a systematic review and meta-analysis of observational studies to summarise the evidence regarding the strength of the association of occurrence of CI in a PCOS pregnant woman compared to a non-PCOS pregnant woman...

PURPOSE: To evaluate the effect of intrahepatic cholestasis of pregnancy (ICP) with gestational diabetes mellitus (GDM) on perinatal outcomes and establish a prediction model of adverse perinatal outcomes in women with ICP. METHODS: This multicenter retrospective cohort study included the clinical data of 2,178 pregnant women with ICP, including 1,788 women with ICP and 390 co-occurrence ICP and GDM. The data of all subjects were collected from hospital electronic medical records...

The main causes of maternal mortality are comorbidities, hypertensive pregnancy syndrome, obstetric haemorrhage, and maternal sepsis. For this reason, uterotonics, magnesium sulphate, and antibiotics are essential tools in the management of obstetric patients during labour and in the peripartum period. These drugs are widely used by anaesthesiologists in all departments, and play a crucial role in treatment and patient safety. For the purpose of this narrative review, we performed a detailed search of medical databases and selected studies describing the use of these drugs in patients during pregnancy, delivery and the pospartum period...

INTRODUCTION: Prematurity is an urgent public health problem worldwide. Recent studies associate maternal hypovitaminosis D during pregnancy with an increased risk of prematurity. However, the evidence on this association remains inconclusive, and there is lack of consensus in the literature. The exact mechanism by which low vitamin D levels may increase the risk of preterm birth is not yet fully understood. Nevertheless, it is known that vitamin D may play a role in maintaining a healthy pregnancy by regulating inflammation and immunomodulation by acting on the maternal and fetal immune systems...

INTRODUCTION: Women with polycystic ovary syndrome (PCOS) have more pregnancy complications like gestational diabetes, hypertension, and preterm labor than other women. Metformin has been used in an attempt to improve pregnancy outcomes. Our study aims to explore childbirth experiences in women with PCOS compared with a reference population. It also explores the potential influence of metformin, obesity, pregnancy complications, and the duration and mode of birth on childbirth experiences...

Pre-term birth is associated with significant neonatal morbidity and mortality. Pre-term births are associated with significant health and neuro-developmental risks in childhood and adulthood. Women with multiple pregnancies are at much higher risks. Low levels of omega-3 long-chain polyunsaturated fatty acids (PUFAs), such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are associated with higher risk of pre-term labour and increased consumption of foods rich in omega-3 PUFA or supplements are associated with a 11 % and 42 % risk reduction of early and late preterm births, respectively...
