A targeted lifestyle intervention programme based on the principles of motivational interviewing reduces GWG and levels of anxiety in obese pregnant women.

Our insight into the complications associated with monochorionic twins has increased in recent years. It is hoped that this will lead to better surveillance and ultimately an improved outcome for these high-risk pregnancies.

The aim of this study was to evaluate the role of MR imaging of the fetus to improve sonographic prenatal diagnosis of congenital anomalies. In 40 fetuses (not consecutive cases) with an abnormality diagnosed with ultrasound, additional MR imaging was performed. The basic sequence was a T2-weighted single-shot half Fourier (HASTE) technique. Head, neck, spinal, thoracic, urogenital, and abdominal fetal pathologies were found. This retrospective, observational study compared MR imaging findings with ultrasonographic findings regarding detection, topography, and etiology of the pathology. The MR findings were evaluated as superior, equal to, or inferior compared with US, in consent with the referring gynecologists. The role of these findings in relation to pregnancy management was studied and compared with postnatal follow-up in 30 of 40 babies. Fetal MRI technique was successful in 36 of 39 examinations and provided additional information in 21 of 40 fetuses (one twin pregnancy with two members to evaluate). More precise anatomy and location of fetal pathology (20 of 40 cases) and additional etiologic information (8 of 40 cases) were substantial advantages in cerebrospinal abnormalities [ventriculomegaly, encephalocele, vein of Galen malformation, callosal malformations, meningo(myelo)cele], in retroperitoneal abnormalities (lymphangioma, renal agenesis, multicystic renal dysplasia), and in neck/thoracic pathology [cervical cystic teratoma, congenital hernia diaphragmatica, congenital cystic adenomatoid lung malformation (CCAM)]. This improved parental counseling and pregnancy management in 15 pregnancies. In 3 cases, prenatal MRI findings did not correlate with prenatal ultrasonographic findings or neonatal diagnosis. The MRI provided a more detailed description and insight into fetal anatomy, pathology, and etiology in the vast majority of these selected cases. This improved prenatal parental counseling and postnatal therapeutic planning.

We present a retrospective study of the frequency and type of associated malformations and chromosomal anomalies in 42 consecutive cases of congenital diaphragmatic hernia (CDH) diagnosed in utero during the period from 1985 to 1999. In 26% (11/42) of the cases, associated malformations were detected. Chromosomal anomalies were present in 9.5% (4/42). In this group of 15 cases (15/42 = 36%) with associated malformations or chromosomal anomalies, all cases, except one, had prenatal sonographic evidence of additional problems. The survival rate of fetuses with CDH and associated malformations or chromosomal anomalies was poor (1/15). Therefore, the overall survival rate of in utero-diagnosed CDH was only 31% (13/42), while isolated left CDH had a survival rate of 52% (12/23). The in utero diagnosis of CDH implies a detailed echographic examination to exclude additional anomalies. The risk for a syndromal or chromosomal malformation becomes small when no additional anomalies are seen on ultrasound.

The etiology of the fetal akinesia deformation sequence (FADS) is heterogeneous and can be the result of neurogenic and myopathic disorders, restrictive dermopathy, teratogen exposure, and intrauterine constraint. We present the prenatal and fetopathological findings in a consecutive series of 30 affected fetuses with normal chromosomal results. According to the in utero time of onset of the fetal akinesia, the severity of the phenotype varied from a severe, generalized FADS in the early-onset group to milder defects, as isolated distal arthrogryposis in the late-onset group. No more than 10% (3/30) were diagnosed in the first trimester of pregnancy and all presented a severe phenotype. Twenty-seven of the thirty (90%) were diagnosed after the first trimester, with a severe FADS in 15/27 and a milder phenotype of distal arthrogryposis in 12/27. In all 30 patients, extensive neuropathological studies (brain, spinal cord, and muscles) were performed. In 16 patients (53%) a specific diagnosis could be made (central nervous system abnormalities 9/16; spinal cord 1/16; primary myopathy 3/16; syndromic 3/16). In 10 others (33%), pathological neuromuscular findings were present but no definitive diagnosis was established. In 4 patients (13%), neuromuscular findings were normal, and the etiology of the FADS remained unexplained.

Background: The psychological health in obese women during pregnancy has been poorly studied. Objective: To compare levels of anxiety and depressed mood during pregnancy in obese versus normal-weight women. Methods: 63 obese pregnant women and 156 normal-weight controls were included prospectively before 15 weeks of gestation. Levels of state and trait anxiety and depressed mood were measured during the first, second and third trimester of pregnancy. A linear mixed-effect model with repeated measures was used to evaluate group differences. Results: The levels of state anxiety significantly increased from trimester 1 to trimester 3 in obese pregnant women (beta = 3.70; p = 0.007), while this parameter remained constant throughout pregnancy in normal-weight women. Levels of trait anxiety and depressed mood significantly decreased from trimester 1 to trimester 2 in controls, but not in obese pregnant women. Variables such as maternal education, ethnicity, marital state, psychological history and miscarriages, parity and smoking behaviour had significant effects on anxiety and/or depressed moods during pregnancy. Obese pregnant women show higher levels of anxiety and depressive symptomatology compared to normal-weight pregnant women. Conclusion: Interventional programmes aiming at preventing the deleterious influence of maternal obesity on perinatal outcomes should include a psycho-educational program specifically tailored to this high-risk group.
