Perinatal outcomes in women with class IV obesity compared to women in the normal or overweight body mass index categories: A population-based cohort study in Qatar.

Background: The prevalence of childhood and adult obesity is rising exponentially worldwide. Class IV obesity (body mass index, BMI ≥50 kg/m2) is associated with a higher risk of adverse perinatal outcomes. This study compared these outcomes between women with class IV obesity and women in the normal or overweight categories during pregnancy. Methods: A retrospective cohort study was performed in Qatar, including women having singleton live births beyond 24 weeks of gestation, classified into two class IV obesity and normal/overweight (BMI between 18.5 and 30.0 kg/m2). The outcome measures included the mode of delivery, development of gestational diabetes and hypertension, fetal macrosomia, small for date baby, preterm birth and neonatal morbidity. Adjusted odds ratios (aOR) with 95% confidence intervals (95% CI) were determined using multivariable logistic regression models. Results: A total of 247 women with class IV obesity were compared with 6797 normal/overweight women. Adjusted analysis showed that women with class IV obesity had 3.2 times higher odds of cesarean delivery (aOR: 3.19, CI: 2.26-4.50), 3.4 times higher odds of gestational diabetes (aOR: 3.39, CI: 2.55-4.50), 4.2 times higher odds of gestational hypertension (aOR: 4.18, CI: 2.45-7.13) and neonatal morbidity (aOR: 4.27, CI: 3.01-6.05), and 6.5 times higher odds of macrosomia (aOR 6.48, CI 4.22-9.99). Conclusions: Class IV obesity is associated with more adverse perinatal outcomes compared with the normal or overweight BMI categories. The study results emphasized the need for specialized antenatal obesity clinics to address the associated risks and reduce complications.

Impact of bariatric surgery on maternal gestational weight gain and pregnancy outcomes in women with obesity: A population-based cohort study from Qatar.

BACKGROUND: Bariatric surgery is performed in obese women of reproductive age to help achieve a healthy prepregnancy weight to reduce the complications associated with obesity in pregnancy. However, these procedures can impact maternal nutrition and gestational weight gain (GWG). This study evaluates the maternal and neonatal outcomes in women with prepregnancy bariatric surgery and determines the impact on GWG. METHODS: This study included 24 weeks gestation or more pregnancies, with a maternal BMI at delivery of 30 kg/m2 or more. It was categorized into two groups based on whether they had prepregnancy bariatric surgery (exposed) or not (unexposed). The outcomes included gestational diabetes (GDM), gestational hypertension (GHT), mode of delivery, preterm birth (PTB), GWG, birthweight (BW) and customized BW centiles, low birthweight (LBW), congenital anomalies, and admission to the neonatal intensive unit (NICU). Categorization was also done based on the adequacy of GWG (low, adequate, and excess). RESULTS: A total of 8,323 women were included in the study, 194 of whom had prepregnancy bariatric surgery. After adjusting for confounders, the exposed group had a mean GWG 1.33 kg higher than the unexposed group (95% CI 0.55-2.13, p = 0.001). The exposed group had higher odds of PTB (aOR 1.78, 95% CI 1.16-2.74, p = 0.008), CD (aOR 6.52, 95% CI 4.28-9.93, p < 0.001), LBW in term babies (aOR 2.60, 95% CI 1.34-5.03, p = 0.005), congenital anomalies (aOR 2.64, 95% CI 1.21-5.77, p = 0.015), low APGAR score (aOR 3.75, 95% CI 1.12-12.5, p = 0.032) and 80.4g lesser birthweight (95% CI -153.0, -5.8; p = 0.034). More women in the low GWG category had LBW babies (28.6% versus 6.7% in the high GWG group, p = 0.033), lowest mean BW and median BW centiles (2775 grams versus 3289 grams in the high GWG group, p = 0.004 and 57.5% versus 74.5% in the high GWG group, p = 0.040, respectively). CONCLUSION: The findings of this study highlight differences in perinatal outcomes such as preterm birth, low birth weight, congenital anomalies, cesarean deliveries, and gestational weight gain between post-bariatric women and controls. These insights can help inform the planning and provision of appropriate maternity care to enhance patient safety and outcomes. The results of this study can also guide the counseling of reproductive age-group women who are planning to undergo bariatric surgery.

Maternal and neonatal outcomes associated with multiple repeat cesarean deliveries: A registry-based study from Qatar.

BACKGROUND: Cesarean delivery (CD) is associated with increased maternal and neonatal morbidity compared to vaginal delivery, particularly in cases classified as emergency procedures or when there are multiple CDs. This retrospective cohort study aims to examine the incidence of maternal and neonatal complications in women with multiple CDs. METHODS: This study used data from a national perinatal database obtained from a single tertiary maternity care hospital. Women who delivered a singleton live birth after 24 weeks of gestation by CD were stratified into five groups based on the number of CDs, with the last group having five or more CDs. The women were divided into those with five or more CDs (Group 5) versus those with fewer than five (Groups 1 to 4). The maternal outcomes included intra-operative surgical complications, blood loss, and intensive care unit (ICU) admission. The neonatal outcomes included preterm birth, neonatal ICU (NICU) admission, respiratory distress syndrome (RDS), and perinatal death. RESULTS: Of the 6,316 women in the study, 2,608 (41.3%) had a primary CD. 30.3%, 17.5%, and 7.3% of the cohort had their second, third, and fourth CDs, respectively. Women undergoing the 5th CD and above formed the remaining 3.5% (227). Women in Group 5 had the highest risk of suffering a surgical complication (3.1%, p = 0.015) and postpartum hemorrhage (7.5%, p = 0.010). 24% of babies in Group 5 were born preterm (p < 0.001). They also had a 3.5 times higher risk of having a surgical complication (RR = 3.5, 95% CI 1.6-7.6, p = 0.002), a 1.8 times higher risk of developing postpartum hemorrhage (RR = 1.8, 95% CI 1.1-2.9, p = 0.014), a 1.7 times higher risk of delivering between 32-37 weeks of gestation (RR = 1.7, 95% CI 1.3-2.2, p < 0.001), a higher risk of the baby getting admitted to NICU (RR = 1.3, 95% CI 1.0-1.6, p = 0.038), and developing RDS (RR = 1.5, 95% CI 1.2-2.0, p = 0.002) compared to Groups 1-4. The risks of neonatal outcomes such as NICU admission (RR 2.9, 95% CI 2.1-4.0) and RDS (RR 3.5, 95% CI 2.3-5.5) were much higher in elective CDs performed at term compared to preterm births (p < 0.001 for both). CONCLUSION: Maternal morbidity significantly increases with the increasing number of CD. The increased risk of RDS and NICU admissions in the neonate with multiple CDs reflects lower gestational age and birthweight in these groups-consideration of preoperative steroids for lung maturation in these women to reduce neonatal morbidity warrants further discussion.

Maternal Body Mass Index and Recommended Gestational Weight Gain in a Middle Eastern Setting.

OBJECTIVE: Maternal body mass index (BMI) and gestational weight gain (GWG) are modifiable risk factors that influence pregnancy outcomes. We examined the association between the two factors in pregnant women in Qatar with regard to the GWG recommendations by the Institute of Medicine (IOM) in 2009. METHODS: We performed a population-based retrospective cohort analysis of 3547 singleton births, using routinely collected data from a Middle Eastern hospital database. RESULTS: The mean maternal age was 29.7 ± 5.5 years, prepregnancy BMI was 27.5 ± 5.8 kg/m2, GWG was 9.58 kg ± 6.87 kg and gestational age at birth was 38.5 ± 1.9 weeks. In line with IOM recommendations, we found that higher BMI was correlated with decreased GWG and BMI was significantly associated with GWG even after adjusting for maternal age, parity, and infants' gestational age at birth. Nonetheless, GWG in more than one-third of women who were overweight or obese exceeded the IOM recommendation.

Review of socioeconomic risk factors for cesarean births: a population-based study.

OBJECTIVES: The reasons for increased cesarean section (CS) rates are complex and multifactorial. The goal of this study was to look at different social and economic factors that might be causing more cases of CS in the population. STUDY DESIGN: A retrospective population-based cohort study. Data was taken from the Perinatal Neonatal Outcomes Research study in the Arabian Gulf (PEARL study) registry. Data from 60,728 live births ≥ 24 weeks of gestation were analyzed. In this study, various socioeconomic factors, such as maternal nationality, religion, educational level, employment status, parental income, consanguinity, housing, preterm birth, and tall stature, were examined for women undergoing cesarean section (CS) and their economic outcomes. Women who underwent vaginal delivery (VD) were compared. There are risks associated with pregnancy, smoking, assisted conception, and prenatal care. RESULTS: 60,728 births ≥ 24 weeks gestation were included in the analysis. 17,535 women delivered by CS (28.9%). Women with university-level -education and above were more likely to deliver by CS (61%), as compared to illiterate women or women with basic education at elementary or secondary levels (OR 0.73, CI 95%: P: <0.0001). Working women were more likely to deliver by CS (OR 1.40, CI 95%, P value <0.0001). Women living in rented houses were less likely to achieve a normal delivery (71.8%) (OR 1.40, CI 95%; P: <0.0001) as compared to women living in owned houses (74.7%). Women over 20 years old tended to achieve more VD compared to women less than 20 years old. P value <0.0001. Smoking was associated with lower chances of VD, with 42.4% of smokers delivered by CS compared to 28.3% of non-smokers (OR 1.87, CI 95%; P: <0.0001). Assisted conception was associated with higher CS rates as compared to spontaneous conceptions (OR 0.39; P: <0.0001). We found no statistically significant differences in how babies were born based on the mother's nationality, the father's job, or the mother's income. CONCLUSIONS: Higher education, employed mothers, smoking, and living in rented houses were socioeconomic factors associated with a higher rate of CS in our population. Furthermore, women who had regular antenatal care were more at risk for delivery by cesarean section, which could be related to other comorbidities increasing the likelihood of cesarean birth rather than antenatal care itself. In our population, assisted reproduction was associated with a higher probability of cesarean delivery.

Prevalence, predictors, and outcomes of major congenital anomalies: A population-based register study.

Congenital anomalies (CAs) are a leading cause of morbidity and mortality in early life. We aimed to assess the incidence, risk factors, and outcomes of major CAs in the State of Qatar. A population-based retrospective data analysis of registry data retrieved from the Perinatal Neonatal Outcomes Research Study in the Arabian Gulf (PEARL-Peristat Study) between April 2017 and March 2018. The sample included 25,204 newborn records, which were audited between April 2017 and March 2018, of which 25,073 live births were identified and included in the study. Maternal risk factors and neonatal outcomes were assessed for association with specific CAs, including chromosomal/genetic, central nervous system (CNS), cardiovascular system (CVS), facial, renal, multiple congenital anomalies (MCAs) using univariate and multivariate analyses. The incidence of any CA among live births was 1.3% (n = 332). The most common CAs were CVS (n = 117; 35%), MCAs (n = 69, 21%), chromosomal/genetic (51; 15%), renal (n = 39; 12%), CNS (n = 20; 6%), facial (14, 4%), and other (GIT, Resp, Urogenital, Skeletal) (n = 22, 7%) anomalies. Multivariable regression analysis showed that multiple pregnancies, parity ≥ 1, maternal BMI, and demographic factors (mother's age and ethnicity, and infant's gender) were associated with various specific CAs. In-hospital mortality rate due to CAs was estimated to be 15.4%. CAs were significantly associated with high rates of caesarean deliveries (aOR 1.51; 95% CI 1.04-2.19), Apgar < 7 at 1 min (aOR 5.44; 95% CI 3.10-9.55), Apgar < 7 at 5 min (aOR 17.26; 95% CI 6.31-47.18), in-hospital mortality (aOR 76.16; 37.96-152.8), admission to neonatal intensive care unit (NICU) or perinatal death of neonate in labor room (LR)/operation theatre (OT) (aOR 34.03; 95% CI 20.51-56.46), prematurity (aOR 4.17; 95% CI 2.75-6.32), and low birth weight (aOR 5.88; 95% CI 3.92-8.82) before and after adjustment for the significant risk factors. This is the first study to assess the incidence, maternal risk factors, and neonatal outcomes associated with CAs in the state of Qatar. Therefore, a specialized congenital anomaly data registry is needed to identify risk factors and outcomes. In addition, counselling of mothers and their families may help to identify specific needs for pregnant women and their babies.

Perinatal outcomes of intrahepatic cholestasis of pregnancy from two birth cohorts: A population-based study.

Background: Intrahepatic cholestasis of pregnancy (ICP) is a complex liver disease with varying incidence worldwide. We compared ICP incidence and pregnancy outcomes with outcomes for normal pregnant controls. Methods: We conducted a retrospective data analysis of perinatal registry data for the years 2011 and 2017 to compare the following outcome measures: stillbirths, labour induction, gestational diabetes, pre-eclampsia, antepartum haemorrhage, postpartum haemorrhage, preterm births, low Apgar score, acute neonatal respiratory morbidity, meconium aspiration and in-hospital neonatal death. Results: The incidence of ICP was 8 per 1000 births from a total 31,493 singleton births with more cases in 2017 than in 2011. Women with ICP were almost six times more likely to have labour induced including significantly more moderate preterm births (defined as between 32 weeks and 36 weeks and 6 days of gestation)) seen more in 2011 than in 2017. Conclusion: Women with ICP showed higher incidence of moderate preterm birth and induced labour but favourable maternal and neonatal outcomes.

Clinical characteristics, diagnosis, and management outcome of surfactant deficiency respiratory distress syndrome in term and near-term neonates. A retrospective observational study.

AIM: This study aims to describe the clinical characteristics of SRDS in term and late preterm neonates. METHODS: This is an observation retrospective chart review of full-term and late preterm neonates born older than 35 to 41 weeks gestation age diagnosed with SRDS. The diagnosis was based on clinical & radiological manifestations of SRDS. RESULTS: 1547 neonates were admitted during this period to NICU with a diagnosis of increased work of breathing for further management. 117 cases of term and near-term neonates (mean GA = 36.8 wks) had a confirmed diagnosis of Surfactant deficiency SRDS. Who compared 60 preterm neonates with SRDS less than 35 weeks gestation (mean GA 27.5 wks) as a control. The mean birth weight was 2.8 kg vs 1.1 kg in the preterm group. SRDS occurs more among the male gender (58%), with CS in 78.6 % of all diagnosed cases. No apparent cause was found in 28.2 %, while 37.6% of all cases were born to mothers with diabetes mellitus, and 27% were born to mothers with either GBs infection, maternal chorioamnionitis, or prolonged rupture of the membrane. CONCLUSION: SRDS is not uncommon among full-term and near-term neonates (10/1000 live birth). By far, the most common associated risk factors are maternal diabetes mellitus and cesarean section. It affects males more than females. Most cases will run a mild-to-moderate course that responds to non-invasive ventilation.

Pre-eclampsia: incidence, determinants, and pregnancy outcomes from maternity hospitals in Qatar: a population-based case-control study.

BACKGROUND: We aimed to study the maternal characteristics and obstetric and neonatal outcomes in pregnant mothers with pre-eclampsia (PE) compared to normotensive. METHODS: This was a population-based retrospective data analysis. Data were obtained from the PEARL-Peristat Study perinatal registry (Perinatal Neonatal Outcomes Research Study in the Arabian Gulf) Qatar. The birth periods ranged from January to December 2017 in the main Women's Hospital (now named Women's Wellness Research Center) and March to December 2017 in other hospitals. This study examined 19762 singleton births at 24 weeks of gestation and above. This analysis included only 19,194 births with complete data in the registry database at the time of this analysis, divided into normotensive women (n = 18,735) and women with PE (n = 459) excluding women with gestational hypertension and chronic hypertension without superimposed PE(n = 568). We compared the maternal characteristics of mothers with PE with normotensive mothers and studied the obstetric and neonatal outcomes including cesarean section, stillbirths, prematurity, fetal growth restriction and postpartum hemorrhage (PPH). RESULTS: The prevalence of hypertensive disorders among the 19,762 singleton pregnancies was 1027/19,762 (5.1%). The incidence of pre-eclampsia was 459/19,762 (2.3%) while gestational (341/19,762 (1.7%) and chronic hypertension 219/19,762 (1.1%)). A history of PE or eclampsia in past pregnancies was reported in 12.9% vs 0.9% p < .001 of PE vs normotensive women, respectively. After adjusting for significant maternal risk factors using multivariate logistic regression anlaysis, it was noted that PE was significantly associated with a higher odds for cesarean section (odds ratio (OR), 2.67 (95% CI, 2.19-3.25); p < .001), acute maternal morbidity (OR, 16.42 (95% CI, 5.58-48.30); p < .001), still births (OR, 3.27 (95% CI, 1.56-6.83); p < .001), preterm births (OR, 8.67 (95% CI, 7.05-10.65); p < .001), NICU admissions (OR, 4.41 (95% CI, 3.61-5.38); p < .001) and low birth weight (OR, 7.93 (95% CI, 6.43-9.29); p < .001). CONCLUSION: Women with pre-eclampsia when compared to the normotensive women, they are older, nulliparous, diabetic and obese with an increased risk of preterm birth and cesarean deliveries. It was noted that PE was significantly associated with acute maternal morbidity, still births, cesarean section and preterm births. By taking preventive measures, prompt delivery and appropriate care we can reduce the risks associated with it or prolong the pregnancy to a gestational period which is considered safe for the neonatal survival. Therefore it's imperative to be aware of the population-based risk factors and its mode of presentation in order to give a timely appropriate care and to prevent severe maternal and fetal morbidities and mortalities.

Incidence, risk factors, and feto-maternal outcomes of inappropriate birth weight for gestational age among singleton live births in Qatar: A population-based study.

BACKGROUND: Abnormal fetal growth can be associated with factors during pregnancy and at postpartum. OBJECTIVE: In this study, we aimed to assess the incidence, risk factors, and feto-maternal outcomes associated with small-for-gestational age (SGA) and large-for-gestational age (LGA) infants. METHODS: We performed a population-based retrospective study on 14,641 singleton live births registered in the PEARL-Peristat Study between April 2017 and March 2018 in Qatar. We estimated the incidence and examined the risk factors and outcomes using univariate and multivariate analysis. RESULTS: SGA and LGA incidence rates were 6.0% and 15.6%, respectively. In-hospital mortality among SGA and LGA infants was 2.5% and 0.3%, respectively, while for NICU admission or death in labor room and operation theatre was 28.9% and 14.9% respectively. Preterm babies were more likely to be born SGA (aRR, 2.31; 95% CI, 1.45-3.57) but male infants (aRR, 0.57; 95% CI, 0.4-0.81), those born to parous (aRR 0.66; 95% CI, 0.45-0.93), or overweight (aRR, 0.64; 95% CI, 0.42-0.97) mothers were less likely to be born SGA. On the other hand, males (aRR, 1.82; 95% CI, 1.49-2.19), infants born to parous mothers (aRR 2.16; 95% CI, 1.63-2.82), or to mothers with gestational diabetes mellitus (aRR 1.36; 95% CI, 1.11-1.66), or pre-gestational diabetes mellitus (aRR 2.58; 95% CI, 1.8-3.47) were significantly more likely to be LGA. SGA infants were at high risk of in-hospital mortality (aRR, 226.56; 95% CI, 3.47-318.22), neonatal intensive care unit admission or death in labor room or operation theatre (aRR, 2.14 (1.36-3.22). CONCLUSION: Monitoring should be coordinated to alleviate the risks of inappropriate fetal growth and the associated adverse consequences.

Socioeconomic Risk Factors for Preterm Birth in the state of Qatar: A Population-based Study.

OBJECTIVES: To review the demographics and socioeconomic determinants of preterm birth (PTB) compared to term births among the Qatari population. METHODS: This was a retrospective data analysis of 59,308 births. Data were retrieved from a Population-based Cohort Study. Data were gathered from the PEARL-Peristat maternal newborn registry for 2011, 2012, 2017, and 2018. We compared the preterm births group (delivery < 37 weeks) with the term group (delivery ≥ 37 weeks) regarding socioeconomic factors, including maternal nationality, religion, level of education, mother's occupation, family income, housing, consanguinity, early childbearing, high-risk pregnancy, smoking, assisted conception, antenatal care, and place of delivery. RESULTS: The prevalence of preterm birth was 9%. There were more Saudi nations in the preterm group compared to term (33% vs. 28%, p-value < 0.001). There were more preterm births than term births among working mothers (40% vs. 35%), high-risk pregnancies (24% vs. 18%), those that has used assisted conception (18% vs. 3%), those without antenatal care (11% vs. 5.6%), and those delivered in a tertiary women hospital (88.5% vs. 84.5%) (all p-values < 0.001). There were more women living in villas (41% vs. 38%, p = 0.01) and more smokers (0.8% vs. 0.5%, p = 0.030) in the preterm group than in the term group. There were no differences between the two groups regarding religion, level of maternal education, family income, and early childbearing. CONCLUSION: In our population, we identified several factors associated with preterm births, the most important is Lack of antenatal care , assisted conception and working mothers.

Incidence, Risk Factors, and Outcomes of Preterm and Early Term Births: A Population-Based Register Study.

Preterm birth (PTB) and early term birth (ETB) are associated with high risks of perinatal mortality and morbidity. While extreme to very PTBs have been extensively studied, studies on infants born at later stages of pregnancy, particularly late PTBs and ETBs, are lacking. In this study, we aimed to assess the incidence, risk factors, and feto-maternal outcomes of PTB and ETB births in Qatar. We examined 15,865 singleton live births using 12-month retrospective registry data from the PEARL-Peristat Study. PTB and ETB incidence rates were 8.8% and 33.7%, respectively. PTB and ETB in-hospital mortality rates were 16.9% and 0.2%, respectively. Advanced maternal age, pre-gestational diabetes mellitus (PGDM), assisted pregnancies, and preterm history independently predicted both PTB and ETB, whereas chromosomal and congenital abnormalities were found to be independent predictors of PTB but not ETB. All groups of PTB and ETB were significantly associated with low birth weight (LBW), large for gestational age (LGA) births, caesarean delivery, and neonatal intensive care unit (NICU)/or death of neonate in labor room (LR)/operation theatre (OT). On the other hand, all or some groups of PTB were significantly associated with small for gestational age (SGA) births, Apgar < 7 at 1 and 5 min and in-hospital mortality. The findings of this study may serve as a basis for taking better clinical decisions with accurate assessment of risk factors, complications, and predictions of PTB and ETB.

The neonatal respiratory morbidity associated with early term caesarean section - an emerging pandemic.

OBJECTIVES: To examine the impact of early term caesarean section (CS) on respiratory morbidity and early neonatal outcomes when elective caesarean section was carried out before 39 completed weeks gestation in our population. METHODS: A one-year population-based retrospective cohort analysis using routinely collected hospital data. Livebirths from women who had elective lower segment cesarean section (ELSCS) for uncomplicated singleton pregnancies at early term (ET) 37+0 to 38+6 weeks were compared to full term (FT)≥39+0 weeks gestation. Exclusion criteria included diabetes, antenatal corticosteroid use, stillbirths, immediate neonatal deaths, normal vaginal deliveries and emergency caesareans sections. The outcomes were combined respiratory morbidity (tachypnea [TTN] and respiratory distress syndrome [RDS]), Apgar <7 at 5 min of age, respiratory support, duration of respiratory support and NICU admission. RESULTS: Out of a total of 1,466 elective CS with term livebirths, the timing of CS was early term (ET) n=758 (52%) and full term (FT) n=708 (48%). There was a higher incidence of respiratory morbidities and neonatal outcomes in the ET in comparison to FT newborns. In the univariable analysis, significant risks for outcomes were: the need for oxygen support OR 2.42 (95% C.I. 1.38-4.22), respiratory distress syndrome and/or transient tachypnea of newborn (RDSF/TTN) OR 2.44 (95% C.I. 1.33-4.47) and neonatal intensive care unit (NICU) admission OR 1.91 (95% C.I. 1.22-2.98). Only the need for oxygen support remained (OR 1.81, 95% C.I. 1.0-3.26) in the multivariable analysis. These results were observed within the context of a significantly higher proportion of older, multiparous, and higher number of previous caesarean sections in the early term CS group. CONCLUSIONS: There is a significant risk of respiratory morbidities in infants born by elective cesarean section prior to full term gestation. Obstetricians should aim towards reducing the high rate of women with previous multiple cesarean sections including balancing the obstetric indication of early delivery among such women with the evident risk of neonatal respiratory morbidity.

Antenatal corticosteroids and short-term neonatal outcomes in term and near-term infants of diabetic mothers. Analysis of the Qatar PEARL-peristat registry.

OBJECTIVES: A recent discussion surrounding the extension of antenatal corticosteroid (ACS) use beyond 34 weeks of gestation did not include the subgroup of infants of diabetic mothers (IDM). We aimed to examine the association between ACS exposure and outcomes in neonates born at term and at near-term gestation in a large cohort of IDMs. METHODS: We selected 13976 eligible near-term and term infants who were included in the PEARL-Peristat Perinatal Registry Study (PPS). We assessed the association of ACS exposure with neonatal outcomes in a multivariate regression model that controlled for diabetes mellitus (DM) and other perinatal variables. RESULTS: The incidence of DM was 28% (3,895 of 13,976) in the cohort. Caesarean section was performed in one-third of the study population. The incidence of ACS exposure was low (1.8%) and typically occurred>2 weeks before delivery. The incidence rates of respiratory distress syndrome (RDS)/ transient tachypnoea of newborns (TTN), all-cause neonatal intensive care unit (NICU) admissions, NICU admissions for hypoglycaemia, and low 5-min Apgar scores were 3.5, 8.8, 1.3, and 0.1%, respectively. In a multivariate regression model, ACS was associated with a slight increase in NICU admissions (OR: 1.44; 95% CI: 1.04-2.03; p=0.028), but not with RDS/TTN. CONCLUSIONS: Although the low exposure rate was a limitation, ACS administration did not reduce respiratory morbidity in near-term or term IDMs. It was independently associated with an increase in NICU admissions. Randomized controlled trials are required to assess the efficacy and safety of ACS administration in diabetic mothers at late gestation.

Maternal characteristics and pregnancy outcomes of women with chronic hypertension: a population-based study.

Background We aimed to study the maternal characteristics and obstetric and neonatal outcomes in pregnant mothers with chronic hypertension (CHTN) compared to non-CHTN. Methods The study was a population-based cohort study, and a PEARL-Peristat Study (PPS) for the year of 2017. There were 20,210 total births including 19,762 singleton and 448 multiple births. We excluded multiple gestations from the analysis as they differ in fetal growth, duration of gestation and have a higher rate of obstetric and neonatal complications. We compared the maternal characteristics of mothers with pre-existing HTN with non-hypertensive mothers and studied the obstetric and neonatal outcomes including cesarean section, stillbirths, prematurity, macrosomia and postpartum hemorrhage (PPH). Results We identified 223 births of mothers with essential HTN. The overall prevalence of CHTN in our population was 1.1% (223/20,210). In regard to maternal characteristics, women with CHTN were at or above 35 years of age at the time of delivery 58.9% compared to non-CHTN women 18.7%, P-value <0.001. Pre-existing diabetes was found more in women with CHTN 15.1% compared to non-CHTN women 1.9%, P-value <0.001; while obesity was found in 64% of women with CHTN compared to 32.5% in non-CHTN women, P-value <0.001. Preterm birth was noted in 26% compared to 8% in CHTN compared to non-CHTN women, respectively, P-value <0.001. The rate of stillbirth was similar between the two groups, 0.9% compared to 0.6% in CHTN compared to non-CHTN women, respectively, P-value 0.369. Conclusion Hypertensive mothers have multiple other comorbidities. When compared to the general population, they are older, parous, diabetic and obese with an increased risk of preterm birth and cesarean deliveries. Lifestyle modification, extensive pre-conceptional counseling and multidisciplinary antenatal care are required for such a high-risk group.

The effect of different forms of dysglycemia during pregnancy on maternal and fetal outcomes in treated women and comparison with large cohort studies.

AIMS OF THE STUDY: We describe the impact of different forms of dysglycemia on maternal and neonatal health. This research is a part of the PEARL-Peristat Maternal and newborn registry, funded by Qatar National Research Fund (QNRF) Doha, Qatar. METHODS: A population-based retrospective data analysis of 12,255 women with singleton pregnancies screened during the year 2016-2017, of which 3,027 women were identified with gestation diabetes mellitus (GDM) during pregnancy and 233 were diabetic before pregnancy. Data on maternal outcome was collected from the PEARL-Peristat Maternal and newborn registry. RESULTS: The prevalence of GDM and diabetes mellitus (DM) was 24.7 % and 1.9%, respectively. 55% of DM, 38% of GDM and 25.6% of controls were obese (p<0.001). 71% of pregnant women with DM and 57.8% of those with GDM were older than 30 years versus 44.2% of controls. Pregnant women with DM or GDM had higher prevalence of hypertension versus normal controls (9.9%, 5.5% and 3.5%, respectively; p<0.001). Among women with vaginal deliveries, the proportion of women with induction of labor was significantly higher in the DM and GDM compared to control subjects (33.9%, 26.5% and 12.4%, respectively; p<0.001). The number of women who underwent Cesarean section was significantly higher in the DM and GDM groups versus normal controls (51.9%, 36.8%, and 28.5%, respectively; p<0.001).  Preterm delivery was significantly higher in women with DM and GDM (13.7% and 9%, respectively versus normal women (6.4%); p<0.001). Babies of DM and GDM had significantly higher occurrence of respiratory distress (RDS) or transient tachypnea (TTS): 9% and 5.8 % versus normal controls (4.8%). Macrosomia was more prevalent in babies of DM (6.4%) and GDM (6.8%) compared to controls (5%) (p: <0.001). Significant hypoglycemic episodes occurred more frequently in babies of DM and GDM women (11.2% and 3%, respectively) versus controls (0.6%) (p: <0.001. Infants of DM and GDM mothers required more treatments of phototherapy (9.4% and 8.9%, respectively) versus those born to normal women (7.2%) (p: 0.006). The prevalence of congenital anomalies and neonatal death did not differ between the groups. CONCLUSIONS: Despite the improvement in the prenatal diagnosis and management of dysglycemia, there is still a higher prevalence of prematurity, macrosomia, and hypoglycemia in infants of mothers with DM and GDM. Measurements to reduce obesity and control dysglycemia in women during the childbearing period are highly required to prevent the still higher morbidity during pregnancy.

Scimitar syndrome with absent right pulmonary artery and severe pulmonary hypertension treated with coil occlusion of aortopulmonary collaterals in a term neonate.

Scimitar syndrome (SS) is a rare congenital malformation with an estimated incidence of approximately 2 in 100 000 births. A wide clinical spectrum is observed in children with this syndrome. The common clinical presentation in infancy is respiratory distress and tachypnoea due to associated pulmonary hypoplasia, pulmonary overcirculation and/or pulmonary hypertension. Babies with SS presenting with cardiac failure are prone to develop exaggerated pulmonary vascular disease. Hence early intervention, using either coil embolisation or surgical intervention, is indicated. We are reporting a case of a term baby boy who presented with respiratory failure during the first 24 h of life. Echocardiogram and CT angiogram revealed SS. The baby needed intubation due to respiratory failure. Aortopulmonary collaterals, identified on aortic angiogram, were successfully occluded with detachable coils.

Clinical, biochemical, and radiological manifestations of vitamin D deficiency in newborns presented with hypocalcemia.

INTRODUCTION: The Clinical and radiological manifestations of newborns with severe VDD have not been studied well. MATERIALS AND METHODS: We studied the clinical, biochemical, and radiological manifestations of 10 full-term (FT) newborns (6: M, 4: F) infant presented to with symptomatic hypocalcemia (seizure) secondary to vitamin D deficiency (VDD) during the first 10 days of life are described. All were exclusively breastfed since birth. All their mothers have low 25 hydroxy vitamin D (25OHD) level <10 ng/mL and were not taking vitamin supplements during pregnancy. RESULTS: FT newborns with hypocalcemia secondary to VDD presented with generalized convulsions (10/10) and craniotabes (8/10), but none had rachitic chest rosaries or joint broadening. Cranial ultrasonographic evaluation was normal. Serum 25OHD concentrations were low in these newborns (13.2 ± 3.8 ng/mL) and their mothers (8.1 ± 1.5 ng/mL). A total of 60% of them had increased parathormone (PTH) concentrations (>60 ng/mL) and 60% had decreased magnesium (Mg) concentrations (<0.7 mmol/L). Their alkaline phosphatase (ALP) concentrations were significantly higher than normal newborns. All other laboratory results (liver function tests, urea and electrolytes, C reactive protein, lumbar puncture, blood culture, and lactate) were normal. In all patients, seizures ceased within 2 days of starting treatment with alphacalcidol and calcium. Radiological manifestations included metaphyseal band of relative lucency (osteopenia), just under the line of provisional calcification, within distal radius (7/10), femur (4/10), and tibia (3/10), mild cupping and haziness of distal radius (2/10). DISCUSSION: Newborns with VDD had significantly lower serum calcium, ALP and PTH and higher phosphate concentrations, compared to older infants with VDD rickets. In newborns with VDD, serum calcium levels were correlated significantly with 25OHD (r = 0.597, P < 0.001), Mg concentrations (r = 0.436, P < 0.001) and negatively with ALP concentrations (r = -0.451, P < 0.001). Serum PTH concentrations were correlated significantly with serum Mg (r = 0.78, P < 0.0001) but not with serum calcium (r = -0.103, P = 0.3) or 25OHD (r = -0.03, P = 0.7) concentrations. CONCLUSION: The clinical, biochemical, and radiological manifestations of VDD in newborns indicate that they are less adapted to VDD compared to older infants. VD supplementation for mothers and newborns should be considered to avoid short-term complications of VDD in the neonatal period and on the growing infants especially in countries with high prevalence of VDD.

Gestational age specific neonatal survival in the State of Qatar (2003-2008) - a comparative study with international benchmarks.

OBJECTIVE: To analyze and compare the current gestational age specific neonatal survival rates between Qatar and international benchmarks. STUDY DESIGN: An analytical comparative study. PLACE AND DURATION OF STUDY: Women's Hospital, Hamad Medical Corporation, Doha, Qatar, from 2003-2008. METHODOLOGY: Six year's (2003-2008) gestational age specific neonatal mortality data was stratified for each completed week of gestation at birth from 24 weeks till term. The data from World Health Statistics by WHO (2010), Vermont Oxford Network (VON, 2007) and National Statistics United Kingdom (2006) were used as international benchmarks for comparative analysis. RESULTS: A total of 82,002 babies were born during the study period. Qatar's neonatal mortality rate (NMR) dropped from 6/1000 in 2003 to 4.3/1000 in 2008 (p < 0.05). The overall and gestational age specific neonatal mortality rates of Qatar were comparable with international benchmarks. The survival of < 27 weeks and term babies was better in Qatar (p=0.01 and p < 0.001 respectively) as compared to VON. The survival of > 32 weeks babies was better in UK (p=0.01) as compared to Qatar. The relative risk (RR) of death decreased with increasing gestational age (p < 0.0001). Preterm babies (45%) followed by lethal chromosomal and congenital anomalies (26.5%) were the two leading causes of neonatal deaths in Qatar. CONCLUSION: The current total and gestational age specific neonatal survival rates in the State of Qatar are comparable with international benchmarks. In Qatar, persistently high rates of low birth weight and lethal chromosomal and congenital anomalies significantly contribute towards neonatal mortality.
