BACKGROUND: Toxoplasma gondii, a widely prevalent protozoan parasite, causes serious toxoplasmosis infections in humans and other animals. Among livestock, pigs are susceptible to T. gondii infection. Despite Henan being one of the biggest pig-raising provinces in China, little information exists on the epidemiology of toxoplasmosis in this location. Therefore, we molecularly characterized DNA samples from pigs in Henan. A total of 1647 samples, including 952 from dead piglets, 478 from seriously sick fattening pigs and 217 from abortion sows, were collected from different animal hospitals or pig farms from 10 different cities in Henan (2006-2008)...

OBJECTIVES: The purpose of this study was to evaluate the global sphericity index (GSI) of the 4-chamber view and correlate the results with abnormal ultrasound findings. METHODS: The epicardial end-diastolic basal-apical length (BAL) and transverse length (TL) of the 4-chamber view were measured to compute the GSI (BAL/TL) in 200 control fetuses between 20 and 40 weeks' gestation. Three hundred study fetuses were prospectively examined between 17 and 39 weeks' gestation...

BACKGROUND: Monochorionic twin pregnancies are at increased risk of complications due to sharing a single placenta and potentially developing unbalanced vascular anastomoses. Complications include twin-twin transfusion syndrome (TTTS) which affects 10-15% monochorionic twins, and if untreated has a 70-90% perinatal loss rate. We are currently unable to predict which twins will develop complications or to what severity. We have previously shown differences in angiogenic and placental growth factors in maternal blood in pregnancies complicated by TTTS compared to twin pregnancies not complicated by TTTS but matched for gestation...

BACKGROUND: Myocardial dysfunction occurs in a variety of fetal disorders. Findings from adult cardiology, where n-terminal pro-B-type natriuretic peptide (nt-proBNP) is an established biomarker of left ventricular dysfunction have been extended to fetal life. Since fetal blood sampling is technically challenging we investigated amniotic fluid nt-proBNP for its suitability to diagnose fetal myocardial dysfunction. METHODS: Ultrasound, Doppler examination and echocardiography was applied to classify cases and controls...

INTRODUCTION: To evaluate the largest vertical pocket (LVP) of amniotic fluid as a time-dependent factor to predict perinatal mortality in women with early preterm premature rupture of membranes (EPPROM). MATERIAL AND METHODS: Observational cohort study of singleton pregnancies with EPPROM <24 weeks. Termination of pregnancy (TOP) was considered if the LVP was <2 cm at 7 days. The maternal and neonatal characteristics of ongoing pregnancies were recorded. Prediction of perinatal mortality was estimated based on the influence of the LVP as a time-dependent factor after adjustment for maternal age, prior invasive procedure, and gestational age at EPPROM...

BACKGROUND: Chronic hypertension in adults causes arterial lengthening in major arteries, but the effects of early fetal hypertension on the twin-twin transfusion syndrome recipient's vascular architecture remains unknown. OBJECTIVE: We hypothesize that arterial cord redundancy is related to recipient hypertension and subsequent heart failure. Our objectives were to: (1) establish a 3-dimensional color Doppler ultrasound method of measuring umbilical arterial length relative to its corresponding venous segment in the umbilical cord using artery vein angle; (2) compare recipient artery vein angle to gestational age-matched controls; and (3) test the association of artery vein angle with recipient heart failure...

OBJECTIVE: Cervical length measurement has been uggested as a useful tool for predicting intra-amniotic infection/inflammation in preterm labor, but little information is available in the setting of preterm premature rupture of membranes (pPROM). We aimed to determine whether a short cervical length is independently associated with an increased risk of intra-amniotic infection or inflammation and impending preterm delivery in women with pPROM. METHODS: This was a retrospective cohort study involving 171 consecutive singleton pregnant women with pPROM (21+0-33+6 weeks' gestation), who underwent amniocentesis...

PURPOSE: Meconium-stained amniotic fluid (MSAF) is rarely observed in preterm pregnancies, and its clinical significance is undetermined. We evaluated the correlation between MSAF and obstetrical and perinatal complications prior to 34 weeks' gestation. MATERIALS AND METHODS: Pregnancies complicated with MSAF between 24 and 34 weeks of gestation were compared with same gestational age-matched controls. The variables measured were: obstetrical complications: clinical chorioamnionitis, Intrahepatic Cohlestasis of Pregnancy - ICP, Intra Uterine Growth Restriction - IUGR, preeclampsia, gestational diabetes; nonobstetrical complications; and perinatal complications: cord around neck/body, Apgar <7 at 5 min, cord pH, Neonatal Intensive Care Unit - NICU admission, complications during NICU hospitalization, and composite outcome...
