Anthropometric Measurements to Predict NICU Admission for Infants of Diabetic Mothers

Aim: Can NICU admission of IDM be predicted by anthropometric measurements like birth weight, lenght, head circumference (HC), mid upper arm circumference (MUAC) or triceps skin fold thickness (TSFT). Method: Eighty-six-term IDMs were analyzed prospectively. MUAC, HC and TSFT were measured within 48 hours of life. Prenatal-natal-postnatal problems; NICU admission; maternal characteristics, HbA1c were recorded. Results: Mean birth weight, gestational age were 3453.3±582.4g and 38.0±0.97weeks. 63.9% of IDMs was admitted to NICU. 56.3% hospitalized due respiratory problems; 32,7 % required endotracheal intubation. Mean MUAC, TSFT, HC and MUAC/HC ratio were 11.2±1.1 cm, 7.1±2.2 mm, 35.0±1.8 cm and 0.32±0.03 cm respectively for all. Although there was no significant relation between NICU admission and MUAC (p=0.071), TSFT and MUAC/HC were significantly higher in babies admitted to NICU (p=0.006 for TSFT, p<0.001 for MUAC/HC). HC was significantly low in babies followed in NICU (P<0.001). With increment of TSFT, MUAC/HC and HbA1c, NICU admission increases positively, but HC affects NICU admission negatively (OR for TSFT:1.6, OR for MUAC/HC: 2.1, OR for HbA1c: OR for HC:0,3). Mechanic ventilation requirement is affected positively by TSFT (p=0.008, OR:1.5) and affected negatively by HC (p=0.004, OR:0.6). Conclusion: This preliminary study showed; TSFT, HC and MUAC/HC ratio are helpful criterias to predict NICU admission risk for IDMs and might be helpful for risk assesment in limited settings.

Maternal and foetal outcome in preterm births in a rural tertiary care centre: a retrospective study

Background: Preterm birth (PTB) is one of the main causes of perinatal mortality and morbidity. It can also result in long term health consequences for both mother and the newborn. The objective was to assess maternal and fetal morbidity and mortality in PTBs.Methods: A retrospective study was done in the department of obstetrics and gynecology in a tertiary care hospital during January 2020 and June 2020. Ninety-three women with records of preterm births were analyzed for maternal and fetal outcomes. coGuide statistical software was used for data analysis.Results: 48.39% of the women were between 20 to 24 years of age. The majority (50.54%) were primigravida. The main causes for PTB among the study participants were medical disorders (39.78%), PPROM (29.03%), spontaneous labor without any underlying cause (18.28%). 51.61% had a vaginal delivery, 88.17% had a live birth. The majority of 52 (55.91%) neonates had birth weights between 1.51 to 2.5 kg. Fifty-nine neonates (63.44%) needed NICU admission. The reason for NICU admission in majority 25 (26.88%) was respiratory distress.Conclusions: Timely, early diagnosis and treatment of medical disorders among antenatal women can aid in reducing the occurrence of preterm births and their associated morbidity and mortality. Medical disorders and premature preterm rupture of membrane remain the main causes of preterm birth.

A study of effects of hypothyroidism on antenatal patients

Background: After diabetes mellitus, thyroid disorders are the most common endocrine disorders in pregnancy. The most common thyroid gland dysfunction in pregnancy is hypothyroidism with estimated prevalence of 1.5-4.4% of pregnant women. Effects of hypothyroidism in pregnancy include anemia, pre-eclampsia, prematurity, IUGR, low birth weight, mental retardation in neonate. The objective of this study is to find the association of hypothyroidism and its adverse outcomes on mother and the fetus that is listed above.Methods: A study was conducted over a period of 6 months over 50 antenatal patients with hypothyroidism from Jan 2021 to August 2021 in the department of obstetrics and gynecology, Cama and Albless hospital, Mumbai with inclusion, exclusion criteria. History of infertility, family history of thyroid disease, menstrual pattern, recurrent abortion and fetal outcomes were the main study variables.Results: In this study, majority of hypothyroidism belonged to the age group of 26-30 years (54%). A high prevalence was found in G2 (26%) and antenatal hypothyroidism with past h/0 abortions were found in 26% patients. Low birth weight is found in 32% cases of hypothyroidism, NICU admissions seen in 32% cases of hypothyroidism, 22% cases were found to have anemia.Conclusions: Hypothyroidism is a common health problem in antenatal patients. We concluded that hypothyroidism is more commonly seen to be associated with low birth weight, anemia, pre-eclampsia, NICU admission in neonate. Early ANC registration and regular ANC checkups help in early recognition and initiating early treatment, thus improving fetomaternal outcome.

The implications for advanced maternal age on pregnancy complications and adverse neonatal outcomes

Objective This study aimed to determine the effect of advanced maternal age (AMA) on maternal and neonatal outcomes in pregnant women aged ≥35 years compared with patients aged 30–34 years. Also, we aimed to analyze the risk estimates of potential confounders to identify whether these variables contributed to the development of adverse pregnancy outcomes or not. Methods This retrospective cohort study included 2284 pregnant women aged ≥35 years at the time of delivery who was delivered in a tertiary referral hospital from January 1, 2016, to December 31, 2020. We further classified these women into two subgroups: 35–39 years as early AMA (EAMA), and ≥40 years as very AMA (VAMA). Pregnancy complications and adverse neonatal outcomes were recorded. Results Compared to younger women, pregnant AMA women had significantly higher risks of complicated pregnancies, including a higher risk of gestational diabetes mellitus (GDM, p<0.001), polyhydramnios (p<0.001), cesarean section (p<0.001), stillbirths (p<0.001), major fetal abnormality (p<0.001), preterm delivery (p<0.001), lower birth weight (p<0.001), lower 5-minute Apgar scores (p<0.001), lower umbilical artery blood pH values (p<0.001), neonatal intensive care unit (NICU) admission (p<0.001), and length of NICU stay (p<0.001). Conclusion We found a strong and significant association between VAMA and adverse pregnancy outcomes, including an increased risk of GDM, polyhydramnios, cesarean section, and adverse neonatal outcomes, including a higher risk of stillbirths, preterm delivery, lower birth weight, lower 5-minute Apgar scores, and NICU admission.

Impact of Co-Existing Placental Pathologies in Pregnancies Complicated by Placental Abruption and Acute Neonatal Outcomes

Placental abruption (PA) is a concern for maternal and neonatal morbidity. Adverse neonatal outcomes in the setting of PA include higher risk of prematurity. Placental pathologies include maternal vascular malperfusion (MVM), fetal vascular malperfusion (FVM), acute chorioamnionitis, and villitis of unknown etiology (VUE). We aimed to investigate how placental pathology contributes to acute neonatal outcome in PA. A retrospective cohort study of all placentas with PA were identified. Exposures were MVM, FVM, acute chorioamnionitis and VUE. The primary outcome was NICU admission and the secondary outcomes included adverse base deficit and Apgar scores, need for resuscitation, and small-for-gestational age. A total of 287 placentas were identified. There were 160 (59.9%) of placentas with PA alone vs 107 (40.1%) with PA and additional placental pathologies. Odds of NICU admission were more than two times higher in pregnancies with placental pathologies (OR = 2.37, 95% CI 1.28–4.52). These estimates were in large part mediated by prematurity and birthweight, indirect effect acting through prematurity was OR 1.79 (95% CI 1.12–2.75) and through birthweight OR 2.12 (95% CI 1.40–3.18). Odds of Apgar score ≤ 5 was more than four times higher among pregnancies with placental pathologies (OR = 4.56, 95% CI 1.28–21.26). Coexisting placental pathology may impact Apgar scores in pregnancies complicated by PA. This knowledge could be used by neonatal teams to mobilize resources in anticipation of the need for neonatal resuscitation.

Fetal monitoring from 39 weeks’ gestation to identify South Asian-born women at risk of perinatal compromise: a retrospective cohort study

To investigate whether earlier “post-term” monitoring of South Asian (SA) pregnancies from 39 weeks’ gestation with amniotic fluid index (AFI) and cardiotocography (CTG) detected suspected fetal compromise. Retrospective cohort study of all SA-born women at an Australian health service with uncomplicated, singleton pregnancies following the introduction of twice-weekly AFI and CTG monitoring from 39 weeks. Monitoring results, and their association with a perinatal compromise composite (including assisted delivery for fetal compromise, stillbirth, and NICU admission) were determined. 771 SA-born women had earlier monitoring, triggering delivery in 82 (10.6%). 31 (4%) had a non-reassuring antepartum CTG (abnormal fetal heart rate or variability, or decelerations) and 21 (2.7%) had an abnormal AFI (≤ 5 cm). Women with abnormal monitoring were 53% (95% CI 1.2–1.9) more likely to experience perinatal compromise and 83% (95% CI 1.2–2.9) more likely to experience intrapartum compromise than women with normal monitoring. Monitoring from 39 weeks identified possible fetal compromise earlier than it otherwise would have been, and triggered intervention in 10% of women. Without robust evidence to guide timing of birth in SA-born women to reduce rates of stillbirth, earlier monitoring provides an alternative to routine induction of labour.

Trends in neonatal intensive care unit admissions by race/ethnicity in the United States, 2008–2018

To examine temporal trends of NICU admissions in the U.S. by race/ethnicity, we conducted a retrospective cohort analysis using natality files provided by the National Center for Health Statistics at the U.S. Centers for Disease Control and Prevention. A total of 38,011,843 births in 2008–2018 were included. Crude and risk-adjusted NICU admission rates, overall and stratified by birth weight group, were compared between white, black, and Hispanic infants. Crude NICU admission rates increased from 6.62% (95% CI 6.59–6.65) to 9.07% (95% CI 9.04–9.10) between 2008 and 2018. The largest percentage increase was observed among Hispanic infants (51.4%) compared to white (29.1%) and black (32.4%) infants. Overall risk-adjusted rates differed little by race/ethnicity, but birth weight-stratified analysis revealed that racial/ethnic differences diminished in the very low birth weight (< 1500 g) and moderately low birth weight (1500–2499 g) groups. Overall NICU admission rates increased by 37% from 2008 to 2018, and the increasing trends were observed among all racial and ethnic groups. Diminished racial/ethnic differences in NICU admission rates in very low birth weight infants may reflect improved access to timely appropriate NICU care among high-risk infants through increasing health care coverage coupled with growing NICU supply.

Cerebroplacental ratio for prediction of adverse intrapartum and neonatal outcomes in a term uncomplicated pregnancy

Background Fetal hypoxia is one of the major causes of high perinatal morbidity and mortality rates. Doppler ultrasound tests such as cerebroplacental ratio (CPR) evaluation are commonly used to assess blood flow disturbances in placento-umbilical and feto-cerebral circulations. A low cerebroplacental ratio has been shown to be associated with an increased risk of stillbirth regardless of the gestation or fetal weight. We conducted this study to assess the fetal cerebroplacental ratio in prediction of adverse intrapartum and neonatal outcomes in a term, uncomplicated pregnancy to reduce fetal and neonatal morbidity and mortality. Results It was found that neonates with CPR ≤1.1 had significantly higher frequencies of cesarean delivery (CS) for intrapartum fetal compromise compared to those with CPR >1.1 (p=0.043). Neonates with CPR ≤1.1 had significantly lower Apgar score at 1 min and 5 min than those with CPR >1.1 (p=0.004) and (p=0.003), respectively. Neonates with CPR ≤1.1 had significantly higher rates of NICU admission than those with CPR <1.1 (p=0.004). Conclusion The cerebroplacental ratio shows the highest sensitivity in the prediction of fetal heart rate abnormalities and adverse neonatal outcome in uncomplicated pregnancies at term. The cerebroplacental ratio index is useful in clinical practice in antenatal monitoring of these women in order to select those at high risk of intra- and postpartum complications.
