Mid trimester

Annah Lane, Ling Lee, Donna Traves, Andreas Lee
INTRODUCTION: The antenatal diagnosis of open spina bifida (OSB), a neural tube defect, is predominantly made at the second trimester morphology scan by ultrasound detection of structural abnormalities resulting from the associated Chiari II malformation. Evidence has emerged suggesting that these structural abnormalities can be detected earlier, by examination of the posterior fossa as part of the first trimester nuchal translucency scan. In particular, absence of the intra-cranial translucency (IT) of the fourth ventricle has shown promise as a diagnostic marker of OSB, although the sensitivity and specificity of this finding varies widely in the literature...

OBJECTIVES: In 2009, due to increasing congenital syphilis rates, prenatal syphilis tests (PST) at both mid-gestation and delivery were added to first trimester prenatal screening in the province of Alberta. We sought to determine the proportion of mothers who had all three recommended PSTs during this period and to identify factors associated with incomplete PST. METHODS: A cohort of all pregnancies resulting in a live or stillborn infant in Alberta for 2010 and 2011 was developed from Vital Statistics and linked with prenatal screening data to determine the number and timing of PSTs for pregnant women...

OBJECTIVE: Superimposed pre-eclampsia (SPE) is resolved only with the termination of the pregnancy. Therefore, the risk prediction and prevention is very important. We aimed to evaluate the characteristics of patients who develop SPE and their controllable risk factors during mid-trimester. DESIGN AND METHOD: A total of 283 pregnant women with chronic hypertension were included for the study. Blood pressure (BP) and body weight were recorded at 10, 20, 24, 28, and 32 weeks of gestation and pregnancy outcomes were evaluated...

OBJECTIVES: C-reactive protein (CRP) is a well-established general marker of inflammation from both infectious and noninfectious exposures. Previous studies have shown that maternal CRP is associated with an increased risk of autism and schizophrenia. The aim of this study was to examine the association between early to mid-gestational serum CRP levels, prospectively assayed in maternal sera, and the risk of bipolar disorder (BPD). METHODS: This study is derived from the Finnish Prenatal Study of Bipolar Disorder (FIPS-B), based on a nested case-control study design...

BACKGROUND: Hypertensive disorders in pregnancy may affect the cardiovascular risk of offspring. We examined the associations of maternal blood pressure throughout pregnancy and hypertensive disorders in pregnancy with childhood blood pressure of offspring. Specific focus was on the comparison with paternal blood pressure effects, the identification of critical periods, and the role of birth outcomes and childhood body mass index in the observed associations. METHODS AND RESULTS: This study was embedded in a population-based prospective cohort study among 5310 mothers and fathers and their children...

BACKGROUND: Early infancy is a high-risk period for severe acute respiratory infection (ARI), particularly in low-income countries with resource-limited health systems. Lower respiratory tract infection (LRTI) is commonly preceded by upper respiratory infection (URTI), and often caused by respiratory syncytial virus (RSV), influenza and other common community-acquired viral pathogens. Vitamin D status is a candidate modifiable early-life determinant of the host antiviral immune response and thus may influence the risk of ARI-associated morbidity in high-risk populations...

Bilirubin concentrations have been recently reported to be negatively associated with type 2 diabetes mellitus. We examined the association between bilirubin concentrations and gestational diabetes mellitus. In a prospective cohort study, 2969 pregnant women were recruited prior to 16 weeks of gestation and were followed up until delivery. The value of bilirubin was tested and oral glucose tolerance test was conducted to screen gestational diabetes mellitus. The relationship between serum bilirubin concentration and gestational weeks was studied by two-piecewise linear regression...

AIM: We compared the effectiveness of a combined treatment involving cervical pessary plus vaginal progesterone to vaginal progesterone alone in decreasing the rate of preterm birth in women with short cervix in the second gestational trimester. METHODS: This prospective, open-label, randomized clinical trial was conducted on 144 pregnant women with singleton pregnancy who had a cervical length ≤ 25 mm, at 18-22 gestational weeks (GW). Seventy-three patients were assigned to receive 400 mg of daily vaginal progesterone (group A), and 73 to receive cervical pessary plus 400 mg of daily vaginal progesterone (group B), until the 37th GW...

Antenatal diagnosis of congenital heart disease (CHD) is still low even though screening was first introduced over 25 years ago. The purpose of our study was to determine the efficacy of a second-trimester prenatal ultrasonographic method of screening for CHD.From September 2012 to September 2013, the length and width of the fetal ductus venosus were measured sonographically in 1006 singleton fetuses, and the ratio of length to width was calculated. The accuracy of each fetal measurement and Doppler ultrasonography were determined...

Hepatic fat and abdominal adiposity individually reflect insulin resistance, but their combined effect on glucose homeostasis in mid-pregnancy is unknown. A cohort of 476 pregnant women prospectively underwent sonographic assessment of hepatic fat and visceral (VAT) and total (TAT) adipose tissue at 11-14 weeks' gestation. Logistic regression was used to assess the relation between the presence of maternal hepatic fat and/or the upper quartile (Q) of either VAT or TAT and the odds of developing the composite outcome of impaired fasting glucose (IFG), impaired glucose tolerance (IGT) or gestational diabetes mellitus at 24-28 weeks' gestation, based on a 75 g OGTT...
