RESUMEN
OBJECTIVE: To determine the timing of screening for postpartum depression that optimizes access to psychiatric care. METHODS: Cross-sectional evaluation of women receiving obstetric care in a community-based medical center clinic from March to July 2006, who were screened for depression at 36 weeks gestation, delivery, and 6 weeks postpartum using the Edinburgh Postnatal Depression Scale. Positive screens generated referrals for psychiatric evaluation. The rate of positive screens for depression and psychiatric follow-up at each time point was evaluated. RESULTS: Of the 293 patients evaluated, the distribution of the first screen which occurred during the study period was 21% at 36 weeks, 31% at delivery, and 48% at 6 weeks postpartum. The incidence of a positive screen was 5% at 36 weeks, 16% at delivery and 14% at 6 weeks postpartum. Access to psychiatric care occurred in 33% at 36 weeks, 15% at 6 weeks postpartum and 100% at delivery (p = 0.001). CONCLUSION: Screening for depression in the hospital after delivery improves access to psychiatric care.

BACKGROUND: The Edinburgh Postnatal Depression Scale (EPDS) is a well-validated screening tool for the detection of patients at risk for postpartum depression. It was postulated that screening utilizing the EPDS in a directed interview would increase the detection rate compared with a self-completed EPDS in an indigent population. OBJECTIVE: To compare the results of a self-completed EPDS with those of a directed interview utilizing the EPDS in the identification of patients at increased risk for postpartum depression. METHODS: All patients undergoing a 6-week postpartum evaluation in the obstetric clinic at a community teaching hospital between November 1, 2003 and March 31, 2004 were screened for postpartum depression using the self-completed EPDS. This was followed by a directed interview, which consisted of a verbally administered EPDS by a social worker blinded to the results of the self-completed EPDS. A positive screen was defined as an EPDS score of > or =12 by either method. The number of patients with a positive screen to either the self-completed EPDS, the directed interview EPDS, or both were recorded. The two techniques were compared by the McNemar Chi-square test. The self-completed and directed interview EPDS scores were compared by Pearson's correlation coefficient to examine differences in screening techniques. Demographic data and characteristics in each group were examined. RESULTS: Among the 134 patients evaluated, 24 (17.9%) screened positively for being at an increased risk of having postpartum depression. The self-completed EPDS and the directed interview EPDS screening detection rates were not different, identifying 23 (17.2%) and 22 (16.4%) patients, respectively (p = 1.0). The use of the self-completed EPDS and the directed interview EPDS in parallel detected one additional subject (0.7%; p = 0.99). The self-completed EPDS and directed interview EPDS scores correlated significantly (r = 0.94; p = 0.01). The demographics and characteristics of patients with a positive screen were not different from those with a negative screen. CONCLUSIONS: The self-completed EPDS and directed interview EPDS are equivalent screening techniques for postpartum depression. There is no evidence to suggest that parallel screening improves detection. Either technique should be incorporated into the postpartum visit to screen for postpartum depression.

OBJECTIVE: The objective of the study was to examine whether the risk and indications for primary cesarean in the second pregnancy are influenced by changes in prepregnancy body mass index (BMI) between pregnancies. STUDY DESIGN: We performed a cohort analysis using the Missouri maternally linked birth and infant death surveillance datasets (1989-1997), comprised of women with their first 2 consecutive live births (n = 113,789). BMI (kilograms per square meter) was categorized as underweight (less than 18.5 kg/m2), normal (18.5 to 24.9 kg/m2), overweight (25 to 29.9 kg/m2), and obese (30 kg/m2 or greater). Indications for primary cesarean were categorized as breech, dystocia, fetal distress, and others. Timing of primary cesarean was categorized as elective (prior to labor) and emergent (after initiation of labor). Adjusted odds ratio (OR) was used to quantify the associations between changes in prepregnancy BMI and indications for primary cesarean. RESULTS: The rate of primary cesarean in the second pregnancy was 9.2%. Compared with women with normal BMI in their first 2 pregnancies, women who increased their BMI between pregnancies had increased risk of primary cesarean for all indications. Women who remained obese or overweight in both pregnancies were at increased risk of primary cesarean following breech (OR 1.28 and 1.13, respectively); dystocia (OR 1.94 and 1.41, respectively); fetal distress (OR 1.43 and 1.26, respectively); others (OR 3.17 and 1.63, respectively); and elective (OR 2.31 and 1.43, respectively) and emergent (OR 1.66 and 1.30, respectively) cesarean section. Women who lowered their BMI from obese to overweight or overweight to normal between pregnancies had risks of primary cesarean comparable with those with normal BMI in both pregnancies. Any increase in BMI from underweight to overweight or obese between the first 2 pregnancies was associated with increased risk of primary cesarean (OR 1.20 to 3.04) in the second pregnancy. CONCLUSION: Increases in prepregnancy BMI between first 2 pregnancies from normal to obese is associated with increased risk of indications for primary cesarean. The association between being overweight or obese or increases in prepregnancy BMI between pregnancies and primary cesarean in the second pregnancy suggests that counseling women with regard to their high BMI may be beneficial.

OBJECTIVE: The objective of the study was to determine whether placental abruption is associated with an increased incidence of histologic chorioamnionitis among singleton gestations and whether this association is dependent on its severity. STUDY DESIGN: Data were derived from the New Jersey-Placental Abruption Study, an ongoing, multicenter, case-control study conducted in New Jersey since August 2002. Subjects were women with a clinical diagnosis of abruption, and controls were matched to cases based on parity and maternal race/ethnicity. Two perinatal pathologists, blinded to the case-control status, performed all histologic examination based on standardized protocol. The association between chorioamnionitis and abruption was quantified based on odds ratio (OR) with 95% confidence interval (CI), after adjustment for potential confounders, and all analyses were stratified based on preterm birth (less than 37 weeks) status. RESULTS: At preterm gestations (n = 141), chorioamnionitis was present in 30.8% and 12.5% of abruption cases and controls, respectively (OR 3.6, 95% CI 1.7 to 10.5). At term gestations (n = 205), the corresponding rates were 34.6% and 20.4%, respectively (OR 2.8, 95% CI 1.3 to 6.1). Severe chorioamnionitis was 7.2 (95% CI 1.6 to 20.1) and 18.3 (95% CI 2.2 to 150.4) times more common in abruption patients at preterm and term gestations, respectively. CONCLUSION: Histologic chorioamnionitis is associated with placental abruption. The association was strongest in the presence of severe chorioamnionitis at term and, to a lesser extent, at preterm gestations. These observations suggest that the histologic findings in abruption are accompanied by severe inflammation, in both preterm and term gestations.

Fetal growth restriction can result from a variety of intrinsic or extrinsic insults, resulting from maternal, fetal, and placental factors. Determining the underlying cause of poor fetal growth can be difficult but is essential for assessing potential risks for future pregnancies. Importantly, recurrence risks greatly depend on these underlying conditions. Understanding these risks can allow more appropriate patient counseling and may influence management strategies to optimize future pregnancies.

OBJECTIVE: To estimate whether the acid-base status of neonates born to women with meconium-stained amniotic fluid varies across gestation. METHODS: We carried out a retrospective cohort study of all pregnancies that were complicated by meconium-stained amniotic fluid in 2004. Cases were identified from a perinatal pathology database that contained data on all pregnancies complicated by meconium-stained amniotic fluid. Data abstracted from the charts included gestational age at delivery, umbilical arterial pH, birth weight, and the presence or absence of labor. Cases were stratified according to gestational age at delivery. The distribution of meconium-stained amniotic fluid across gestation was computed. The mean umbilical arterial pH values (with 95% confidence intervals) across gestation were assessed by analysis of variance. RESULTS: The mean umbilical arterial pH in women with meconium-stained amniotic fluid did not differ across gestation. The overall incidence of meconium-stained amniotic fluid was 12.0% (766 of 6,403 deliveries). The rates of meconium-stained amniotic fluid increased from 1.2% at 32 weeks to 100% at 42 weeks. CONCLUSION: The rising incidence of meconium-stained amniotic fluid with gestational age is consistent with the hypothesis that fetal maturation is a major etiologic factor in meconium passage. Also, the lack of variation of mean umbilical arterial pH across gestation suggests that fetal acidemia is not increased when meconium passage occurs earlier in pregnancy rather than at later gestational ages.

OBJECTIVE: This study was undertaken to determine the accuracy of our previously published and prospectively validated institution-specific singleton transcerebellar diameter (TCD) nomogram in the prediction of gestational age (GA) in twin pregnancies. We further evaluated whether the prediction of GA in twin gestations using the singleton TCD nomogram differs between monochorionic and dichorionic twins. STUDY DESIGN: In our previously published studies, we retrospectively constructed a cross-sectional nomogram using TCD measurements in 24,026 well-dated, singleton fetuses, and prospectively validated the nomogram using 2,597 singleton fetuses. The current study comprised of 1,278 well-dated twins (19.6% monochorionic) seen in our ultrasound unit between August 1994 and May 2003, and the singleton TCD nomogram was validated in these twin gestations. The actual GA was subtracted from the GA predicted by the TCD nomogram and the concordance between actual and predicted GAs was assessed on the basis of the Pearson's correlation coefficient (r). This was performed separately for monochorionic and dichorionic twins. RESULTS: Concordance between the actual and predicted twin TCD measurements based on our previously published singleton TCD nomogram was high (Pearson's correlation, r = 0.95, P < .0001). Between 16 and 23 weeks' gestation, the predicted mean GA was within 6 days of actual GA. Between 24 and 30 weeks, the predicted mean GA was within 3 days, and at 32 weeks or more, the predicted mean GA was within 5 days of the actual GA. Prediction of GA based on the singleton TCD nomogram was equally accurate in both monochorionic and dichorionic twin gestations (P = .686). CONCLUSION: This study demonstrates that our previously validated singleton TCD nomogram is reliable and accurate in twins irrespective of placental chorionicity.

OBJECTIVE: To evaluate the efficacy of a Down syndrome screening protocol that combines second-trimester maternal serum analytes and the continuous ultrasound measures of nuchal fold thickness and proximal long bone length. METHODS: Ultrasound measurements of nuchal fold, femur length, and humerus length were reviewed for 72 second-trimester Down syndrome and 7063 unaffected fetuses. Derived statistical variables for these parameters were entered into a multivariable Gaussian model together with the statistical variables used in the "quad" test (maternal serum alpha-fetoprotein, unconjugated estriol, human chorionic gonadotropin, and inhibin A). Maternal age-specific sensitivities, false-positive rates, and positive predictive values were generated together with receiver operating characteristic curves. Overall efficacy of ultrasound screening alone, the quad test, and the combination of the ultrasound and quad test were compared using a 1:270 second-trimester risk cutoff applied to 1999 US births. RESULTS: Using ultrasound, a sensitivity of 79.9% and false-positive rate of 6.7% may be achieved (positive predictive value: 1 in 42). The quad test has a sensitivity of 81.5% and false-positive rate of 6.9% (positive predictive value: 1 in 42). The combination of the quad test with nuchal fold and long bone measurements may achieve 90% sensitivity and a 3.1% false-positive rate (positive predictive value: 1 in 18). CONCLUSION: Combining second-trimester serum testing and fetal biometry is a feasible approach to Down syndrome screening, compatible with current obstetric practice. This modality is substantially more effective than either serum screening or ultrasound alone. Efficacy may be comparable to that reported for combined first- and second-trimester (integrated) screening.

OBJECTIVE: Our objectives were to determine patterns of antenatal Down syndrome screening and risk adjustment by maternal-fetal medicine specialists in the United States in 2001. STUDY DESIGN: A survey to investigate Down syndrome screening practice patterns was mailed to the 1,638 members of the Society of Maternal-Fetal Medicine in the United States. Practice demographics, screening patterns, and the numeric risks quoted in counseling were analyzed. RESULTS: Five hundred forty-three specialists (33.2%) responded; 530 of these specialists (97.6%) performed antenatal Down syndrome screening; all of them offered second-trimester screening, and 247 of them (45.5%) offered first-trimester screening. With the use of second-trimester ultrasonography, risk was increased by 69.4% of respondents and decreased by 33.1%. Amniocentesis was the most frequently used diagnostic test (83.2%), with loss rates quoted at 1:100 to 1:1,000. CONCLUSION: Maternal-fetal medicine specialists show a wide in variation practices used for Down syndrome screening, modification of risk, and quoted procedure-related loss rates. This information calls for a consensus regarding risks that are quoted in Down syndrome counseling.
