Anxiety During Pregnancy and Postpartum: Course, Predictors and Comorbidity with Postpartum Depression.

Previous findings on peripartum anxiety are inconsistent in respect to the prevalence and course of peripartum anxiety with comorbidity of depression. Our aim was threefold: (1) to examine the course of elevated anxiety during pregnancy, immediately after childbirth, and six weeks postpartum; (2) to establish comorbidity of postpartum anxiety and postpartum depression (PPD); and (3) to examine predictors of anxiety 6 weeks postpartum. A sample of women (N=272) who were below the cut-off score for clinical depression during pregnancy were assessed in the third trimester of pregnancy, then 2 days and 6 weeks postpartum. Questionnaires on anxiety, pregnancy specific distress, stress, coping styles, social support, and depression were administered at each assessment. Obstetric data were collected from the participants' medical records. The estimated rate of high anxiety was 35% during pregnancy, 17% immediately after childbirth, and 20% six weeks postpartum, showing a decrease in anxiety levels after childbirth. Comorbidity of anxiety and PPD was 75%. Trait anxiety and early postpartum state anxiety are significant predictors of postpartum anxiety. Anxiety is a common peripartum psychological disturbance. Anxiety symptoms overlap with PPD, but not com-pletely, indicating that screening for postpartum mental difficulties should include both depression and anxiety.

Is the Predictability of New-Onset Postpartum Depression Better During Pregnancy or in the Early Postpartum Period? A Prospective Study in Croatian Women.

The researchers' aim was to examine whether it was better to predict new-onset postpartum depression (PPD) during pregnancy or immediately after childbirth. A prospective study conducted in Croatia followed women (N = 272) from the third trimester of pregnancy through the early postpartum period (within the first 3 postpartum days), to 6 weeks postpartum. Questionnaires on depression, anxiety, stress, coping, self-esteem, and social support were administered. Through regression analyses we showed that PPD symptoms could be equally predicted by variables from pregnancy (30.3%) and the early postpartum period (34.0%), with a small advantage of PPD prediction in the early postpartum period.

Biochemical screening of fetal aneuploidies and neural tube defects by "double-test" in Croatia: a 10 years' experience.

The aim of the study is to investigate the efficiency of the second-trimester biochemical screening, with maternal serum alpha-fetoprotein (MS-AFP) and free beta-subunit of human chorionic gonadotropin (free beta-hCG), during the ten-year period. The study included 11,292 of pregnant women between the 15th and 18th gestational week, who underwent screening from November 1996 to December 2006. The risk for trisomy 21 and trisomy 18 were calculated by computer software, based on a model which generated the final risk for fetal aneuploidies from the pregnant woman's a priori age risk and the likelihood ratio of the distribution of the biochemical markers, according to the second-trimester gestation. With the cut-off value of the final risk > or = 1:250, the detection rate for trisomy 21 was 75% (21/28). In women less than or equal to 35, the detection was 57.1% (8/14) and 92.9% (13/14) in those over 35 years, respectively. The detection rate of trisomy 18 was 50% (2/4). The results confirmed that the implementation of double-test, as non-invasive screening for fetal aneuploidies, should be accepted as a complementary method of antenatal care.

Chloasma--the mask of pregnancy.

Chloasma is a required hypermelanosis of sun-exposed areas occurred during pregnancy and it can affect 50-70% of pregnant women. It presents as symmetric hyperpigmented macules, which can confluent or punctuate. The most common locations are the cheeks, the upper lip, the chin and the forehead. The exact mechanism by which pregnancy affects the process of melanogenesis is unknown. Estrogen, progesterone, and melanocyte-stimulating hormone (MSH) levels are normally increased during the third trimester of pregnancy. However, nulliparous patients with chloasma have no increased levels of estrogen or MSH. In addition, the occurrence of melasma with estrogen- and progesterone-containing oral contraceptive pills has been reported. The observation that postmenopausal woman who are given progesterone develop melasma, while those who are given only estrogen do not, implicates progesterone as playing a critical role in the development of melasma. UV-B, UV-A, and visible light are all capable of stimulating melanogenesis. The condition is self-limited; however spontaneous resolution is time-consuming and may take months to resolve normal pigmentation. Therefore, it is worthwhile to prevent the onset of chloasma, by strict photoprotection. Prudent measures to avoid sun exposure include hats and other forms of shade combined with the application of a broad-spectrum sunscreen at least daily. Sunscreens containing physical blockers, such as titanium dioxide and zinc oxide, are preferred over chemical blockers because of their broader protection. Chloasma can be difficult to treat. Quick fixes with destructive modalities (eg, cryotherapy, medium-depth chemical peels, lasers) yield unpredictable results and are associated with a number of potential adverse effects. The mainstay of treatment remains topical depigmenting agents. Hydroquinone (HQ) is most commonly used.

Doppler cerebro-umbilical ratio and fetal biophysical profile in the assessment of peripartal cardiotocography in growth-retarded fetuses.

OBJECTIVE: The aim of the study was to examine the value of the fetal biophysical profile (FBP) and the Doppler cerebro-umbilical ratio (C/U) in the assessment of peripartal cardiotocography (CTG) in growth-retarded fetuses. METHODS: The prospective study included 58 pregnant women with singleton pregnancy from 28 to 42 weeks of gestation with clinically and ultrasonically verified late intrauterine growth retardation (IUGR). After assessment of the FBP, flow velocity waveforms from the umbilical and middle cerebral arteries were recorded and the C/U ratio was calculated. The C/U ratio and the FBP were assessed twice a week. The last peripartal CTG was used as an outcome parameter. RESULTS: The FBP score was statistically significant when associated with peripartal CTG (p < 0.001). The mean value of the FBP was 7.77 +/- 0.28 for infants with a normal peripartal CTG, 6.13 +/- 0.41 for infants with a prepathological CTG and 4.40 +/- 0.60 for infants with a pathological peripartal CTG. There was also a statistically significant association between the C/U ratio > or =1 and normal CTG (p < 0.005), but there was no statistically significant difference between prepathological and pathological CTG in relation to C/U ratio values (p > 0.05). Normal and pathological peripartal CTG was correlated with the perinatal outcome, but prepathological CTG was not correlated with results of the perinatal outcome (p > 0.05). CONCLUSIONS: Our results showed that both methods of fetal monitoring need to be used in perinatal monitoring of growth-retarded fetuses. The two methods can be used as important parameters in deciding to end pregnancies with IUGR when pathological values occur.

[Cross-sectional study of drug use in pregnancy]. / Presjecno istrazivanje (cross-sectional study) uporabe lijekova u trudnoci.

The aim of the paper is to investigate the impact of drugs utilization during pregnancy in the City of Zagreb. This one-month cross-sectional study was conducted in all four Zagreb maternity hospitals using a questionnaire administered to 893 pregnant women. The women used a mean of 2.6 drugs. The vitamin-mineral complex was the leading medicament used by the women during the study period (62.9%) and during pregnancy period. The leading drugs taken between hospital admission and delivery were metoclopramide (10.1%) and diazepam (6.0%). Utilization of diazepam is high during the entire pregnancy. According to FDA risk classification during pregnancy, most drugs are in B class (88%), and in A class (77%). Percent of FDA C class is 16%. In the FDA classes with fetal risk, D class has 47.5%, and X class, with only one woman using drug from this class has a 0.1% of total utilization. In spite of some limitations of the study, the results pointed to the uneconomical, potentially harmful drug use during pregnancy and puerperium, obviously calling for therapy quality upgrading in this vulnerable period of life.

Ultrasonographic estimation of fetal weight--residents accuracy.

The aim of this retrospective study was to evaluate the accuracy of gynecology and obstetrics residents when performing ultrasonographic estimation of fetal weight. The total of 400 ultrasonographic estimations of fetal weight and corresponding neonatal weight were collected and divided into 3 groups according to physicians' experience (junior and senior residents, staff physicians). The accuracy of fetal weight estimation correlated positively with the level of physicians'experience. The proportional difference between ultrasound estimation and actual birth weight varied from 8.45% to 6.88% (junior residents 8.45%, senior residents 6.95%, staff physicians 6.88%). The proportion of ultrasonograhic estimates that fell within 10% of birth weight varied from 59.09% to 79.21% (junior residents 59.09%, senior residents 78.44%, staff physicians 79.21%). Senior residents reach a highly acceptable accuracy in ultrasonographic estimation of fetal weight which is comparable to staff physicians.

Fetal biophysical profile and cerebro-umbilical ratio in assessment of brain damage in growth restricted fetuses.

OBJECTIVE: To examine the relationship between fetal biophysical profile (FBP), Doppler cerebro-umbilical (C/U) ratio and neonatal neurosonography in growth restricted newborns. STUDY DESIGN: This prospective study included 87 growth restricted fetuses from 28 to 42 weeks of gestation. The FBP and C/U ratio were assessed twice a week. Within 48h and on the seventh day after birth, neonatal neurosonography was performed as the outcome parameter. RESULTS: Brain damage was detected, by neurosonography, in 34 newborns with intrauterine growth restriction (IUGR). Severe periventricular echodensities (PVE) were ultrasonographically verified in eleven infants. Intraventricular or intraparenchymal hemorrhage (severe intracranial hemorrhage ICH) was detected in seven infants, and subependymal hemorrhage (SEH) in nine infants with IUGR. Porencephalic cysts, as a result of chronic intrauterine hypoxia, were found in four infants, and brain atrophy was detected in one case. Nonspecific ultrasonographic changes were observed in two newborns. The FBP and C/U ratio were statistically significantly associated with neurosonographicaly verified neonatal brain lesions (P < 0.001). CONCLUSIONS: The FBP and the C/U ratio represent the useful indicators for early detection and assessment of fetal hypoxia. They may also be parameters for the prediction of neonatal neurosonography findings in newborns with IUGR.

Fetal biophysical profile and cerebro-umbilical ratio in assessment of perinatal outcome in growth-restricted fetuses.

AIM: To examine the value of the fetal biophysical profile (FBP) and the Doppler cerebro-umbilical ratio (C/U) in the assessment of perinatal outcome in growth-restricted and hypoxic fetuses. STUDY DESIGN: The prospective clinical study included 87 pregnant women with singleton pregnancies at 28-42 weeks of gestation with clinically verified intrauterine growth restriction (IUGR). After assessment of FBP, flow velocity waveforms from the umbilical and middle cerebral arteries were recorded and the C/U ratio was calculated. The C/U ratio and FBP were assessed twice a week. At delivery, umbilical arterial pH, the occurrence of meconium-stained amniotic fluid (MAF), Apgar score at 5 min and the incidence of cesarean sections were used as outcome parameters. RESULTS: The mean FBP value was 5.5 +/- 0.96 in cases with MAF, and 6.88 +/- 0.26 in cases without MAF. Also, there was no statistical significance in the relation between the C/U ratio and the appearance of MAF. At pH >7.2, the mean FBP value was 7.11 +/- 0.23, while it was 2.83 +/- 0.79 in newborns with acidosis. Both FBP and C/U values were statistically correlated with pH (p < 0.01). The mean umbilical arterial pH was 7.31 +/- 0.0 at a C/U ratio of >/=1 and 7.21 +/- 0.03 at a C/U ratio of <1. In cases with Apgar scores of 8-10, the mean FBP value was 7.28 +/- 0.23, at Apgar scores of 5-7 it was 3.9 +/- 0.52, while at Apgar scores of 0-4 the mean FBP value was 1.5 +/- 0.5. The mean Apgar score at 5 min was 9.54 +/- 0.09 at a C/U ratio of >/=1, and 8.12 +/- 0.49 at a C/U ratio of <1. The mean FBP value in cases of vaginal delivery was 7.55 +/- 0.31. In cesarean section deliveries, the mean FBP value was 5.97 +/- 0.37. Also, there was a high frequency of cesarean sections in growth-restricted fetuses with a C/U ratio of <1 (p < 0.05), i.e. slightly less than FBP. CONCLUSIONS: FBP and C/U ratio were associated with low arterial pH, low Apgar score and the rate of cesarean sections (p < 0.05), but there was no association between FBP or C/U ratio and the appearance of MAF (p > 0.5). Due to their good predictive value the FBP and C/U ratio could be used in the prenatal monitoring of growth-retarded and hypoxic fetuses. These two methods can be used as important parameters in the decision to end pregnancies with IUGR, when pathological values occur. Thus a reduction in perinatal morbidity, mortality and the incidence of infants with poor neurologic outcome can be expected.
