BACKGROUND Obesity is a major clinical problem. The number of obese pregnant women is rising rapidly. The consequences of obesity are significant and affect every aspect of perinatal care for both the mother and the developing fetus. Adipose tissue may be responsible for chronic subclinical inflammation in obesity, being a source of inflammatory mediators. The study was designed to evaluate the analysis of the serum concentration of inflammatory mediators, including interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α), and adiponectin, in obese pregnant women at full-term pregnancies...

BACKGROUND: Maternal sartan intake during pregnancy has been associated with several fetal/neonatal complications related to disturbed renal development. Description of cases: We present two cases of neonatal acute kidney injury (AKI) following valsartan administration during pregnancy and provide evidence for the use of novel AKI biomarkers in these neonates. The first case was a female neonate, delivered at 32+4 weeks of gestation after maternal valsartan intake from 24 to 32 gestational weeks...

BACKGROUND: Gastroschisis is the most common major congenital anomaly managed by paediatric surgeons. The significance of certain associated antenatal ultrasound features in determining fetal outcome is under discussion. AIM: The study aims to define if associated antenatal ultrasound features of gastroschisis are useful prognostic markers for fetal outcome. By establishing the significance of features, including extra- and intra-abdominal bowel dilatation, stomach herniation, stomach dilatation, bowel matting, growth restriction, abnormal umbilical artery (UA) Doppler ultrasounds, and abnormal amniotic fluid volume, it is hoped clinicians will have enhanced ability to counsel parents about the likely outcomes for their infant...

OBJECTIVE: To evaluate the association between ultrasonographic renal parameters and urine biochemistry in fetuses with lower urinary tract obstruction (LUTO). METHODS: Data were collected prospectively from 31 consecutive fetuses with LUTO that underwent vesicocentesis for fetal urinary biochemistry between April 2013 and September 2015. The following renal ultrasound markers were assessed immediately before the vesicocentesis: renal echogenicity, presence of cortical cysts, presence of findings suggestive of 'renal dysplasia' (hyperechogenic cystic kidneys with no cortical-medullary differentiation) and severe oligohydramnios (amniotic fluid < 5th percentile)...

Furcate insertion (FI) is an extremely rare abnormality of umbilical cord insertion. One of the complications associated with FI is hemorrhage from the umbilical vein at the site of FI of the umbilical cord, which can cause sudden intrauterine fetal death. Because of its rarity, no prenatal diagnosis of FI has been reported. A 31-year-old woman at 34 weeks' gestation was referred to us for suspected abnormal cord insertion. Ultrasonography showed normal fetal growth and amniotic fluid volume, with no fetal anomalies...

OBJECTIVE: To demonstrate the feasibility and efficacy of high-intensity focused ultrasound (HIFU) to non-invasively treat placental tissues in a monkey model of pregnancy. MATERIALS AND METHODS: A toroidal HIFU transducer working at 2.5 MHz with an integrated ultrasound-imaging probe was used. Eight pregnant monkeys were exposed to HIFU treatment after anesthesia. Lesions on placental tissues were performed non-invasively by placing the HIFU probe on the skin. Fetal and maternal parameters, such as maternal heart rate, fetal heart rate, and subcutaneous and intra-amniotic fluid temperature, were recorded during HIFU exposure...

BACKGROUND: To date, several studies concerning the effects of induced abortion (IA) on women's later psychosocial well-being and future delivery complications have been published. However, the lack of reports on woman's physical well-being during their first full-term pregnancy occurring after IA is what inspired the current study. Here, we evaluate the physical well-being and use of maternity services of first-time mothers with a history of IA. METHODS: Finnish National Birth Registry data from 2008 to 2010 were linked with the Induced Abortion Registry data from 1983 to 2007...

REVIEW
Dawn S Hughes, Everett F Magann
The evaluation of amniotic fluid volume (AFV) is an established part of the antenatal surveillance of pregnancies at risk for an adverse pregnancy outcome. The two most commonly used ultrasound techniques to estimate AFV are the amniotic fluid index (AFI) and the single deepest pocket (SDP). Four studies have defined normal AFVs, and although their normal volumes have similarities, there are also differences primarily due to the statistical methodology used in each study. Dye-determined AFV correlates with ultrasound estimates for normal fluid volumes but correlates poorly for oligohydramnios and polyhydramnios...

INTRODUCTION: Brain natriuretic peptide (BNP) is synthesized by human fetal membranes, both the amnion and chorion. This locally produced BNP inhibits the contraction of the human myometrium, contributing to the maintenance of myometrial quiescence during pregnancy. Reference values for NT-proBNP concentrations in amniotic fluid at different gestational ages have not been completely defined. We aimed to investigate the range of fetal NT-proBNP values in amniotic fluid in normal pregnancy between 17 and 41weeks of gestation...

Prenatal ultrasound detection of fetal ureterocele with bilateral hydro-ureteronephrosis, obstruction of the bladder outlet and progressive amniotic fluid reduction can be associated with a significant risk of end-stage chronic renal disease after birth. Fetal cystoscopic laser incision of the ureterocele, with the aim of relieving the bladder outflow obstruction to preserve renal function, has been previously reported in one case, with a favourable outcome. This report employed standard 3.5-mm fetoscopic access to the amniotic cavity and the fetal bladder...

To define diagnostic and prognostic markers of parvovirus B19 (B19V) fetal infection, two groups were investigated: 1) pregnant women with specific symptoms or contacts with symptomatic households (n=37); 2) mothers with pathological ultrasound findings and the relevant fetus at the time of prenatal diagnosis (n=16). In the first group, diagnosis of B19V infection was achieved using IgM detection in 29/37 (78.3%) of patients, while B19V DNA was detected in 36/37 (97.3%) of infected women. In the second group, intrauterine infection was investigated by amniocentesis (n=5), cordocentesis (n=3) or both (n=5)...

Zika virus (ZIKAV) infections could potentially occur in Poland due to international travel made by its nationals to regions where the Aedes mosquito is active. A causal relationship between prenatal ZIKAV infection and microcephaly and other serious brain anomalies has been found due to the time association between the infection in pregnancy and a presence of congenital nervous system malformations, together with the detectable pathogen in amniotic fluid and fetus's tissues. Two ZIKAV infection cases of pregnant women who were diagnosed with fetal microcephaly in the state of Paraiba, Brazil, later described in Ultrasound Obstetrics and Gynecology by Oliveira Mello et al...
