Prepregnancy Bmi

The aim of our study was to investigate whether prepregnancy underweight body mass index (BMI) is associated with preterm birth (PTB) and small-for-gestational age (SGA). This retrospective case-control study included 814 women with live singleton fetuses in vertex presentation that gave birth between January 2016 and November 2016 in two tertiary care hospitals. The study group (n = 407) comprised all women whose prepregnancy BMI was underweight (<18.5 kg/m2) and who delivered during the study period. A control group (n = 407) was established with women whose prepregnancy BMI was normal (18.5–24.9 kg/m2) by matching age and parity. Univariate and multivariate analyses were performed to compare PTB and SGA associated with prepregnancy underweight BMI. Compared with the control group, the study group had higher rates of overall PTB (10.1% vs. 5.7%, p = 0.02), iatrogenic PTB (4.2% vs. 1.5%, p = 0.02), and SGA (22.1% vs. 11.1%, p < 0.001). In a multivariable analysis, prepregnancy underweight BMI was associated with PTB (aOR 2.32, 95% CI 1.12–4.81) and with SGA (aOR 2.38, 95% CI 1.58–3.58). In singleton pregnancies, women’s prepregnancy underweight compared with normal BMI was associated with an increase in PTB and in SGA neonates. Identifying this specific high-risk group is pragmatic and practical for all physicians, and they should be aware about perinatal outcome among underweight women.

Meconium Stained Amniotic Fluid

Background: Infants born with meconium stained fluid are at increased risk of fetal hypoxia, evidenced by increased rates of abnormalities indicated by fetal monitoring in labor, low neonatal Apgar scores, and fetal deaths. The study is conducted to determine association of gestational age, Apgar score and neonatal outcomes in newborn born with meconium stained amniotic fluid in tertiary care centre of central India.Methods: The study was conducted over a period of 2 years from January 2012 to January 2014 in Department of Pediatrics, Sri Aurobindo Medical College and Hospital, Indore, Madhya Pradesh, India. One hundred newborns with meconium stained amniotic fluid (study group) and one hundred newborns with clear amniotic fluids (control group) were studied in this period. Gestational age, Apgar score and neonatal outcomes were compared among two groups.Results: The mean gestational age in study group was 38.89±1.14 weeks and in control group was 38.59±0.99 weeks. The mean Apgar score at 1 min was 5.80±1.59 in study group and in the control group was 7.86±0.35. 32 babies in meconium stained liquor had hypoxia of which 11 had respiratory distress, 11 required mechanical ventilation (MAS 08, sepsis 03), 2 newborns had HIE stage 2 and 5 patients died. The above findings suggest higher gestational age, lower Apgar score and poor neonatal outcomes are associated with meconium stained liquor.Conclusions: The study depicts significant co-relation with higher gestational age, lower Apgar at 1 and 5 minutes and poor neonatal outcome in babies with meconium stained amniotic fluid.

Introduction: Prematurity and low birth weight have been associated with increased neonatal morbidity and mortality. This study aimed to evaluate possible risk factors for prematurity associated with fetal growth restriction and being small for gestational age and to determine the incidence of morbidity in these two groups of infants.Material and Methods: Retrospective case-control study of newborns with gestational age of less than 32 weeks, with obstetric diagnosis of fetal growth restriction and with the clinical diagnosis of small for gestational age, admitted to the Neonatal Intensive Care Unit of a tertiary hospital for a period of six years.Results: A total of 356 newborns were studied, with an incidence of 11% of fetal growth restriction and 18% of small for gestational age. Pre-eclampsia was the risk factor for gestation with higher statistical significance (47% vs 16%, p < 0.001) in small for gestational age newborns. There was also a higher incidence of mild bronchopulmonary dysplasia (66% vs 38%, p = 0.005), late sepsis (59% vs 37%, p = 0.003), retinopathy of prematurity (58% vs 26%, p = 0.003) and necrotizing enterocolitis (20% vs 9%, p = 0.005). Mortality was similar in all three groups.Discussion: There were fewer newborn males diagnosed with fetal growth restriction during pregnancy compared to women. Significant differences were observed in the group of these infants regarding the occurrence of chorioamnionitis and pre-eclampsia in comparison to the control group. Newborns with fetal growth restriction and small for age had higher scores on clinical risk indices compared to the control group. In general, small for gestational age newborns had a higher incidence of morbidity than infants with fetal growth restriction and the control group.Conclusion: Advances in neonatal intensive care decreased mortality in preterm infants. However, there are still significant differences in the incidence of morbidity in newborns with growth compromise. The collaboration between obstetricians and neonatologists provides the basis for a correct clinical evaluation, early signaling and global intervention on these newborns, with a significant impact on short and long-term prognosis.

PURPOSE: To describe the Brainstem Auditory Evoked Potential (BAEP) results of full-term small-for-gestational-age newborns, comparing them to the results of full-term appropriate-for-gestational-age newborns, in order to verify whether the small-for-gestational-age condition is a risk indicator for retrocochlear hearing impairment. METHODS: This multicentric prospective cross-sectional study assessed 86 full-term newborns - 47 small- (Study Group) and 39 appropriate-for-gestational-age (Control Group - of both genders, with ages between 2 and 12 days. Newborns with presence of transient evoked otoacoustic emissions and type A tympanometry were included in the study. Quantitative analysis was based on the mean and standard deviation of the absolute latencies of waves I, III and V and interpeak intervals I-III, III-V and I-V, for each group. For qualitative analysis, the BAEP results were classified as normal or altered by analyzing these data considering the age range of the newborn at the time of testing. RESULTS: In the Study Group, nine of the 18 (38%) subjects with altered BAEP results had the condition of small-for-gestational-age as the only risk factor for hearing impairments. In the Control Group, seven (18%) had altered results. Female subjects from the Study Group tended to present more central alterations. In the Control Group, the male group tended to have more alterations. CONCLUSION: Full-term children born small or appropriate for gestational age might present transitory or permanent central hearing impairments, regardless of the presence of risk indicators.

Background: Working with particular substances or under certain working situations may cause some workers to experience abnormalities in their sexual or reproductive health. Occupational exposures can lead to infertility, but the workers may not be aware of such problems. The purpose of the study was to determine the association between male infertility and occupation of industrial workers in organized sector.Methods: Prospective case-controlled study that included 136 industrial workers working in organized sector and attending infertility clinic for treatment. This study included male partners aged between 21-46 years with primary or secondary infertility and undertaking same occupation for at least last three months. Complete infertility workup of all male partners attending infertility clinic was done that included detailed history and information related to occupation. Routine semen parameters were evaluated according to the 2010 World Health Organization (WHO) criteria.Results: In the present study, significant semen abnormalities were observed in male partners with age more than 31 years and undertaking arduous jobs for more than 5 years (p <0.05) in study group (n=136) as compared to control group (n=62). The abnormal semen count were observed in 114 (83.2%) workers in the study group that included 43 (31.6%) with total sperm concentration (TSC) less than 10 million/ml and azoospermia in 44 (32.3%). Reduced motility (asthenozoo-spermia) was observed in majority 125 (91.9%) of male partners. The findings were significant (p <0.05) as compared to control group.Conclusions: Preventive measures in the workplace need to be established to reduce the effect of occupational hazards and its influence in the semen parameters ultimately leading to infertility.

AbstractHuman health effects of airborne lower-chlorinated polychlorinated biphenyls (LC-PCBs) are largely unexplored. Since PCBs may cross the placenta, maternal exposure could potentially have negative consequences for fetal development. We aimed to determine if exposure to airborne PCB during pregnancy was associated with adverse birth outcomes. In this cohort study, exposed women had lived in PCB contaminated apartments at least one year during the 3.6 years before conception or the entire first trimester of pregnancy. The women and their children were followed for birth outcomes in Danish health registers. Logistic regression was performed to estimate odds ratios (OR) for changes in secondary sex ratio, preterm birth, major congenital malformations, cryptorchidism, and being born small for gestational age. We performed linear regression to estimate difference in birth weight among children of exposed and unexposed mothers. All models were adjusted for maternal age, educational level, ethnicity, and calendar time. We identified 885 exposed pregnancies and 3327 unexposed pregnancies. Relative to unexposed women, exposed women had OR 0.97 (95% CI 0.82, 1.15) for secondary sex ratio, OR 1.13 (95% CI 0.76, 1.67) for preterm birth, OR 1.28 (95% CI 0.81, 2.01) for having a child with major malformations, OR 1.73 (95% CI 1.01, 2.95) for cryptorchidism and OR 1.23 (95% CI 0.88, 1.72) for giving birth to a child born small for gestational age. The difference in birth weight for children of exposed compared to unexposed women was − 32 g (95% CI—79, 14). We observed an increased risk of cryptorchidism among boys after maternal airborne LC-PCB exposure, but due to the proxy measure of exposure, inability to perform dose–response analyses, and the lack of comparable literature, larger cohort studies with direct measures of exposure are needed to investigate the safety of airborne LC-PCB exposure during pregnancy

The objective of this study was to evaluate the impact of one abnormal fetus in a twin pregnancy, to compare impact of chorionicity and clinical outcome of intervention and expectant management. Thirty-seven dichorionic (DC) twins and 18 monochorionic (MC) twins complicated with one malformed fetus were evaluated for gestational age, birthweight and perinatal outcome. Six hundred and forty-two twin pregnancies were evaluated in the database. The control groups consisted of 429 DC and 86 MC twins without anomalous fetus. Mean birthweight and gestational age at birth for DC control group were (n= 429; 2137g and 34.71 weeks), DC study group,n= 37; 2117g (p= .338) and 33.97 weeks (p= .311), and DC study group with major malformations,n= 30; 2019g (p= .289) and 33.3 weeks (p= .01), and showed only significance for gestational age. There was no statistical significance between MC control group,n= 86; 2097g and 34.93 weeks, and MC study group,n= 18; 2237g (p= .338), and 34.42 weeks (p= .502). Because of limited data, the preliminary evaluation for expectant management and intervention, and survival of at least one normal fetus showed no impact. We conclude that, although, all DC twin pregnancies have a risk for preterm delivery, DC twins complicated with major malformation of one twin, have a lower mean gestational age at birth. Preliminary results for intervention does not improve fetal outcome for DC and MC twins and needs further evaluation with greater studies of impact or review.

Twin Pregnancies

Twin pregnancies are commonly assessed using singleton growth and birth weight reference charts. This practice has led to a significant number of twins labelled as small for gestational age (SGA), causing unnecessary interventions and increased risk of iatrogenic preterm birth. However, the use of twin-specific charts remains controversial. This study aims to assess whether twin-specific estimated fetal weight (EFW) and birth weight (BW) charts are more predictive of adverse outcomes compared to singleton charts. Centiles of EFW and BW were calculated using previously published singleton and twin charts. Categorical data were compared using Chi-square or McNemar tests. The study included 1740 twin pregnancies, with the following perinatal adverse outcomes recorded: perinatal death, preterm birth <34 weeks, hypertensive disorders of pregnancy (HDP) and admissions to the neonatal unit (NNU). Twin-specific charts identified prenatally and postnatally a smaller proportion of infants as SGA compared to singleton charts. However, twin charts showed a higher percentage of adverse neonatal outcomes in SGA infants than singleton charts. For example, perinatal death (SGA 7.2% vs. appropriate for gestational age (AGA) 2%, p < 0.0001), preterm birth <34 weeks (SGA 42.1% vs. AGA 16.4%, p < 0.0001), HDP (SGA 21.2% vs. AGA 13.5%, p = 0.015) and NNU admissions (SGA 69% vs. AGA 24%, p < 0.0001), when compared to singleton charts (perinatal death: SGA 2% vs. AGA 1%, p = 0.029), preterm birth <34 weeks: (SGA 20.6% vs. AGA 17.4%, p = 0.020), NNU admission: (SGA 34.5% vs. AGA 23.9%, p < 0.000). There was no significant association between HDP and SGA using the singleton charts (p = 0.696). In SGA infants, according to the twin charts, the incidence of abnormal umbilical artery Doppler was significantly more common than in SGA using the singleton chart (27.0% vs. 8.1%, p < 0.001). In conclusion, singleton charts misclassify a large number of twins as at risk of fetal growth restriction. The evidence suggests that the following twin-specific charts could reduce unnecessary medical interventions prenatally and postnatally.
