<b><i>Objective:</i></b> This study aimed to assess reduced fetal growth between 35 weeks of gestation and birth in non-small for gestational age fetuses associated with adverse perinatal outcomes (APOs). <b><i>Material and Method:</i></b> It is a retrospective cohort study of 9,164 non-small for gestational age fetuses estimated by ultrasound at 35 weeks. The difference between the birth weight percentile and the estimated percentile weight (EPW) at 35 weeks of gestation was calculated, and we studied the relationship of this difference with the appearance of APO. APOs were defined as cesarean or instrumental delivery rates for nonreassuring fetal status, 5-min Apgar score &#x3c;7, arterial cord blood pH &#x3c;7.10, and stillbirth. Fetuses that exhibited a percentile decrease between both moments were classified into 6 categories according to the amount of percentile decrease (0.01–10.0, 10.01–20.0, 20.01–30.0, 30.01–40.0, 40.01–50.0, and &#x3e;50.0 percentiles). It was evaluated whether the appearance of APO was related to the amount of this percentile decrease. Relative risk (RR) was calculated in these subgroups to predict APOs in general and for each APO in particular. Receiver operating characteristic and area under curves (AUC) for the difference in the percentile was calculated, used as a continuous parameter in the entire study population. <b><i>Results:</i></b> The median gestational age at delivery in uncomplicated pregnancies was 40.0 (39.1–40.7) and in pregnancies with APOs 40.3 (49.4–41.0), <i>p</i> &#x3c; 0.001. The prevalence of APOs was greater in the group of fetuses with a decrease in percentile (7.6%) compared to those with increased percentile (4.8%) (<i>p</i> &#x3c; 0.001). The RR was 1.63 (95% CI: 1.365–1.944, <i>p</i> &#x3c; 0.001). Although the differences were significant in all decreased percentile groups, RRs were significantly higher when decreased growth values were &#x3e;40 points (RR: 2.036, 95% CI: 1.581–2.623, <i>p</i> &#x3c; 0.001). The estimated value of the AUC for percentile decrease was 0.58 (0.56–0.61, <i>p</i> &#x3c; 0.001). <b><i>Conclusion:</i></b> Fetuses with a decrease in the EPW between the ultrasound at 35 weeks of gestation and birth have a higher risk of APOs, being double in fetuses with a decrease of &#x3e;40 percentile points.

     The aim of the present study was to specify the relationship of gestational period with measurement of Crown-Rump length and Bi-parietal diameter via trans-abdominal ultrasonography in goats. This study was conducted in the Faculty of Veterinary Medicine in Diyala University. The study was carried out on twelve multiparous does, their ages were between 2-5 years. Does were synchronized for estrus with PGF2α (Estrumate) at 11 days apart and naturally served to obtain pregnancy (estrus day=day 0), and subsequently Ultrasonic scanned. Weekly ultrasonographic examinations were performed using 3.5-5MHz sector transducer, from week (5-10) and (6-14) of pregnancy for measuring the Crown-Rump length and Bi-parietal diameter, respectively. The results clearly demonstrated that the relationship between gestational age and Crown-Rump length or Bi-parietal diameter were highly significant (P<0.01). The Crown-Rump length was strongly positively correlated with gestational age (R2=0.99) followed by the Bi-parietal diameter (R2=0.95). In conclusion, the gestational age of goats can be accurately estimated by trans-abdominal ultrasonography measuring of fetal Crown-Rump length and Bi-parietal diameter during first and second trimester of pregnancy.

BackgroundThere is no consensus on the effects that low birth weight, premature birth and intrauterine growth have on later depression.AimsTo review systematically the evidence on the relationship of low birth weight, smallness for gestational age (SGA) and premature birth with adult depression.MethodWe searched the literature for original studies assessing the effect of low birth weight, premature birth and SGA on adult depression. Separate meta-analyses were carried out for each exposure using random and fixed effects models. We evaluated the contribution of methodological covariates to heterogeneity using meta-regression.ResultsWe identified 14 studies evaluating low birth weight, 9 premature birth and 4 SGA. Low birth weight increased the odds of depression (OR = 1.39, 95% CI 1.21–1.60). Premature birth and SGA were not associated with depression, but publication bias might have underestimated the effect of the former and only four studies evaluated SGA.ConclusionsLow birth weight was associated with depression. Future studies evaluating premature birth and SGA are needed.

Placental Thickness

Background: Knowledge of gestational age (GA) is important because it affects clinical management in many ways. Ultrasonography has provided a safe and noninvasive means of dating a pregnancy. The purpose of the present study is to assess the relationship of placental thickness with gestational age and to compare it with other sonographic parameters used to estimate gestational age. Subjects and Methods: The study included 242 normal pregnant women who knew their last menstrual period (LMP). After taking consent, all the women underwent an ultrasound examination. During the scan, besides measuring routine biometric parameters, Placental thickness at the cord insertion was also measured. A retrospective study was designated to test the hypothesis that placental thickness in an age dependant variable and hence can predict gestational age. In the end, the predicted gestational age by placental thickness was compared with gestational age as determined by other sonographic parameters. Results: Placental thickness showed a linear progression in relation to the menstrual age. The correlation coefficient was found to be 0.86(p<0.001). The regression equation was formulated by regressing gestational age on the measured placental thickness. The correlation coefficient between GA-LMP and GA-USG was 0.92 as compared to 0.86 between GA-LMP and GA-PT. The standard error for other USG parameters was +2.32 compared to +2.96 for placental thickness. Conclusion: Placental thickness being a fusion of menstrual age, can be used to predict the gestational age by using the regression formula. Gestational age calculated by other USG parameters is closer to menstrual age as compared to that by placental thickness. The prediction interval was slightly more when the placental thickness was used instead of other USG parameters. Placental thickness is a good alternative parameter for predicting gestational age in the second and third trimester.

Colloid osmotic pressure (COP) of blood was measured directly at birth with the Wescor membrane colloid osmometer (model 4100) in 91 appropriately grown, 11 large, and nine small for gestational age "well" newborn infants. COP correlated directly with birth weight (r = .726, P &lt; .00001) and gestational age (r = .753, P &lt; .00001). COP values for small for gestational age (SGA) and large for gestational age (LGA) infants were found to fall within the 95% prediction interval with regard to birth weight and gestational age for appropriate for gestational age (AGA) infants. Simultaneous measurements of COP, total serum solids, and central arterial mean blood pressure were made. The results showed that COP correlated directly with total serum solids (r = .89, P &lt; .0001) and mean arterial blood pressure (r = .660, P &lt; .001). Among the factors evaluated, total serum solids was the best predictor of COP.

Background: The recently identified hormone kisspeptin has been suggested to play an important regulatory role in placentation. The aim and objective of the study is the measurement of serum kisspeptin level in asymptomatic pregnant women and to find out the association of serum kisspeptin with gestational age in women with early pregnancy.Methods: This was a longitudinal study to the evaluation of 178 asymptomatic pregnant women with a gestation of 6 to 16 weeks attending routine antenatal booking visit recruited as study participants from the Antenatal Clinical of Obstetrics and Gynaecology Department, S.M.S. Medical College and Attached Hospitals, Jaipur, Rajasthan, India.Results: After initial clinical examination of every participant, a single blood sample was taken for the measurement of serum kisspeptin. Serum kisspeptin measurement test was performed by ELISA method and results were expressed as ng/ml. Pregnancy outcome was recorded prospectively. Mean serum kisspeptin level of study participants was 2.80±1.87ng/ml and median were 2.41 (Range 0.244-14.06ng/ml). Our result showed the relationship of serum kisspeptin with gestational age (GA) (p<0.000).Conclusions: serum kisspeptin level increases in pregnancy and showed positive relationship with gestational age significantly (p<0.000).
