Since antepartum and intrapartum risk factors are poor at identifying women whose labor is complicated by shoulder dystocia, sonographic examination of the fetus holds promise. Though there are several measurements of biometric parameters to identify the parturient who will have shoulder dystocia, none are currently clinically useful. Three national guidelines confirm that sonographic measurements do not serve as appropriate diagnostic tests to identify women who will have shoulder dystocia with or without concurrent injury...

Gestational diabetes is the most common endocrine disorder affecting pregnant women and its prevalence is on the rise. Prevalence in Cuba is about 5.8%, and global prevalence ranges from 2% to 18% depending on the criteria applied. Gestational diabetes can lead to adverse gestational outcomes, such as fetal death, preterm delivery, dystocia, perinatal asphyxia and neonatal complications. Prompt, accurate diagnosis allowing early treatment can benefit both mother and child. The disease is asymptomatic, so clinical laboratory testing plays a key role in its screening and diagnosis...

OBJECTIVE: Use of Carpenter-Coustan compared with National Diabetes Data Group criteria increases the number of women diagnosed with gestational diabetes mellitus (GDM) by 30-50%, but whether treatment of this milder GDM reduces adverse outcomes is unknown. We explored the effects of the diagnostic criteria used on the benefits of GDM treatment. METHODS: This was a secondary analysis of a randomized trial for treatment of mild GDM diagnosed using Carpenter-Coustan criteria...

PURPOSE: Dystocia is the leading indication for primary caesarean sections. Our aim is to compare two approaches in the management of dystocia in labor in nulliparous women with a singleton fetus in cephalic presentation at term in spontaneous or induced labor. METHODS: Prospective cohort study. Four hundred and nineteen consecutive patients were divided into two groups: the standard management group (SM), in acceleration of labor was commenced at the "action line" in the case of arrested or protracted labor, and the comprehensive management group (CM) in which arrested or protracted labor was considered as a warning sign promoting further diagnostic assessment prior to considering intervention...

Establishing a definitive cause of bovine abortion is a challenging problem faced by veterinary practitioners and diagnosticians. Detection of an infectious or noninfectious source for abortion may facilitate interventions that mitigate future fetal loss in the herd. The purposes of this study were to identify the most common causes of bovine abortion in cases submitted to the California Animal Health and Food Safety Laboratory System, Davis (CAHFS) from 2007 to 2013 and to determine if detection of infectious pathogens differed with the fetal tissue evaluated...

INTRODUCTION: Labor dystocia (slow or difficult labor or birth) is the most commonly diagnosed aberration of labor and the most frequently documented indication for primary cesarean birth. Yet, dystocia remains a poorly specified diagnostic category, with determinations often varying widely among clinicians. The primary aims of this review are to 1) summarize definitions of active labor and dystocia, as put forth by leading professional obstetric and midwifery organizations in world regions wherein English is the majority language and 2) describe the use of dystocia and related terms in contemporary research studies...

AIMS/HYPOTHESIS: Gestational diabetes mellitus (GDM) is associated with increased risks to mother and child, but globally agreed diagnostic criteria remain elusive. Identification of women with GDM is important, as treatment reduces adverse outcomes such as perinatal death, shoulder dystocia and neonatal hypoglycaemia. Recently, the UK's National Institute for Health and Care Excellence (NICE) recommended new diagnostic thresholds for GDM which are different from the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria endorsed by the WHO...

Abstract Previous approaches to diagnosing gestational diabetes mellitus (GDM) have included 50 g, 75 g and 100 g glucose challenges, lasting 1-3 hours, with 1 or 2 elevations required. Thresholds were validated by their predictive value for subsequent diabetes, or were the same thresholds used in non-pregnant individuals. None were based on their prediction of adverse pregnancy outcomes. Diagnostic paradigms vary throughout the world, making comparisons impossible and severely limiting communication among investigators...

PURPOSE OF REVIEW: Vitamin D status (which is involved in glucose homeostasis) is related to gestational diabetes mellitus (GDM). GDM is characterized by increased resistance to and impaired secretion of insulin and results in higher risk of adverse pregnancy outcomes including operative delivery, macrosomia, shoulder dystocia and neonatal hypoglycemia. Women with GDM and their babies are at increased risk for developing type II diabetes. RECENT FINDINGS: International definitions of vitamin D deficiency and normality are inconsistent...

PURPOSE: This study aimed to correlate pelvic dimensions and fetal size to the risk for cesarean section caused by protracted labor. METHODS: This is an observational, retrospective cohort study on pregnant women with an increased risk of labor dystocia. After pelvimetry, pelvic adequacy was clinically tested in a trial of labor. A multivariable regression analysis was made to identify the risk factors for cesarean section. Two subgroups were established according to the size of the estimated fetal head circumference (HC) (arbitrary cutoffs of ≤340 and >340 mm), and the pelvic measurements were compared by the mode of delivery...

BACKGROUND: Adverse perinatal outcomes are common with pregnancy-related mild glucose intolerance. The perinatal impact of improving this population's health, instead of individual health, has not been quantified. METHODS: We estimated this impact among women with mild glucose intolerance, delivered at The University of North Carolina Women's Hospital from April 1996 to May 2010. We compared observed with predicted risks of perinatal outcomes after simulating a cohort with a one standard deviation decrease in each glucose value...

BACKGROUND: Dystocia is one of the important causes of maternal morbidity and mortality in low-income countries. This study was aimed to determine the diagnostic accuracy of maternal anthropometric measurements as predictors for dystocia in nulliparous women. MATERIALS AND METHODS: This prospective cohort study was conducted on 447 nulliparous women who referred to Omolbanin hospital. Several maternal anthropometric measurements such as height, transverse and vertical diameters of Michaelis sacral rhomboid area, foot length, head circumference, vertebral and lower limb length, symphysio-fundal height, and abdominal girth were taken in cervical dilatation ≤ 5 cm...

CONTEXT: The performance of standard selective screening strategies for gestational diabetes mellitus (GDM) may vary according to ethnicity. OBJECTIVE: We aimed to evaluate the diagnostic and prognostic performance of a selective screening tool to determine whether it accurately predicts GDM and events in women of different ethnicities. The tool selectively screens based on patients having one or more of the following risk factors (RFs): body mass index ≥25 kg/m(2), age ≥35 years, family history of diabetes, and personal history of GDM or macrosomia...
