Maternal education and antenatal attendance in Georgia: A cohort study

Abstract Background Antenatal care (ANC) and maternal education are important determinants for maternal and newborn health outcomes. Understanding the impact of maternal education on ANC is crucial. Purpose To examine the association between maternal education and ANC attendance. Methods A retrospective cohort study utilized nationwide electronic medical birth registry data (2020-2022) in Georgia. the study includes pregnant women and their newborns. A randomized sample was selected, and extracted variables included maternal age, parity, body mass index, education, year of delivery, gestational age, infant sex, Apgar score, birth weight, delivery type, and newborn status. Statistical analysis via IBM SPSS v23 involved chi-square, t-tests, and logistic regression. Results The sample size contains 4976 mothers after excluding cases with missing data (n = 25). The mean maternal age was 30.5 years (SD = 5.4), with a mean BMI of 28.0(SD = 4.8), and the mean gestational week was 38.4(SD = 2.0), with a mean birth weight of 3263.0 (SD = 568.0) grams. Highly educated women had more than 3 times higher odds (OR = 3.636,95%CI:2.575-5.134) of having at least one ANC visit compared to those with Unknown education. primiparous women had significantly higher odds of having at least one ANC visit compared to Multiparous women, OR = 1.519, (95%CI:1.081-2.135). The chi-square test showed significant difference between ANC visits and the number of liveborn/stillborn (χ² = 53.026, p < .001). Moreover, there was a significant association between birth weight categories and ANC visits (χ² = 167.095, p < .001). Conclusions Our study emphasizes the role of education in improving access to ANC among women with low education levels. We can increase ANC visits and improve maternal and newborn health outcomes by focusing educational efforts on pregnant women. Additionally, focusing on high-risk populations, and using tailored interventions can further improve ANC attendance along with maternal and neonatal health. Key messages • Boosting ANC access and improving maternal and neonatal health by tailored community programs. • Conservative communities and underrepresented communities require additional resources to promote tailored healthcare. and extra effort in education about ANC.

The Impact of Antiretroviral Therapy on Birth Outcomes: A Retrospective Cohort Study

Objective: This study aimed to evaluate the impact of highly active antiretroviral therapy (HAART) on pregnancy outcomes at a major tertiary hospital in Abuja, Nigeria. Design: A cohort study was conducted. Methods: HIV-infected pregnant women who initiated HAART during pregnancy for the prevention of mother-to-child transmission (pMTCT) were recruited, alongside a randomly selected group of HIV-uninfected pregnant women. Results: A total of 489 pregnant women participated, including 237 HIV-infected and 252 HIV-uninfected women. HAART initiation during pregnancy was significantly associated with higher mean birth weights (p = 0.0007). While there were 30 cases of low birth weight in the HIV-infected group compared to 21 in the HIV-uninfected group, HAART was not significantly associated with low birth weight (OR 1.59, p = 0.1182). There were 6 stillbirths in the HIV-infected group and 5 in the uninfected group, with no significant association between HIV status and stillbirth (OR 1.28, p = 0.6836). However, 29 preterm deliveries occurred in the HIV-infected group compared to 8 in the uninfected group, showing a strong association between HIV infection and preterm deliveries despite HAART initiation (OR 4.25, p = 0.0002). Conclusion: HIV-infected women receiving HAART during pregnancy have a significantly reduced risk of low birth weight but face an increased risk of preterm delivery.

66 Survival and school-age outcomes of extremely premature neonates with intraventricular hemorrhage

Abstract Background Extremely low gestational age (ELGA) neonates are at risk for intraventricular hemorrhage (IVH) and periventricular hemorrhagic infarction (PVHI). There is no clear consensus on the prognosis of these conditions. Objectives The aim of this study was to compare the survival, and the neurodevelopmental outcomes (NDO) at school-age for neonates with IVH and/or PVHI, to those without. Design/Methods This retrospective single-center study (2012-2017) included neonates less than 26 weeks gestational age (GA) who received resuscitation and early intensive care. Imaging data were collected from cranial US for the presence of IVH described by Papile grading. Survival was defined as survival to discharge. NDO were classified as no neurodevelopmental impairment (NDI), no NDI with multidisciplinary referrals, and the adverse outcome was defined as NDI at school-age. NDI included any diagnosis of cerebral palsy, global developmental delay, intellectual disability, visual or hearing impairment. Autism spectrum disorder (ASD) was included as an outcome of interest. Results 164 infants met inclusion criteria, of whom 156 survived resuscitation. Mean GA was 24 weeks and 6 days (SD 6 days) and mean birth weight 701g (SD 125g), grade I-II IVH was present in 43 (28%) infants, and grade III-IV IVH was present in 48 (31%) infants. Survival was 45% for those with bilateral grade III-IV IVH, 53% for unilateral grade III-IV IVH, 78% for bilateral grade I-II IVH, 80% for unilateral grade I-II IVH, and 81% for no IVH groups. 108 infants survived to discharge and 90 had complete follow up at school age. 30% of children had NDI and ASD was diagnosed in 12%. Logistic regression for adverse outcome demonstrated an adjusted odds-ratio (OR) 0.30 (95% CI 0.14, 0.56) for gestational age (p <0.001). The logistic regression resulted in adjusted OR 0.72 (95% CI 0.21, 2.37) for grade I-II IVH and OR 1.43 (95% CI 0.4, 5.03) for Grade III-IV IVH (p=0.63). Conclusion In neonates born ELGA, survival decreased with increasing severity of IVH. Decreasing GA, but not severity of IVH, was predictive of neurodevelopmental impairment. Extremely preterm infants born < 26 weeks are at high risk of NDI and of ASD.

Perinatal outcomes of selective termination in dichorionic twin pregnancies: a retrospective study from a single center.

Selective termination (ST) is an appropriate procedure for managing discordant fetal anomalies in dichorionic diamniotic (DCDA) twin pregnancies. The aim of this study was to investigate the perinatal outcomes of ST at different gestational ages in DCDA twin pregnancies. This retrospective study was conducted on DCDA twin pregnancies with STs at West China Second University Hospital between January 2012 and December 2022. According to the gestational age at which ST was performed, the patients were assigned to four groups: Group 1 (13 to 17 + 6weeks), Group 2 (18 to 23 + 6weeks), Group 3 (24 to 27 + 6weeks), and Group 4 (≥ 28weeks). We identified 230 patients for this study. The overall rates of miscarriage, preterm delivery at < 32weeks, and term delivery were 1.3%, 10.5%, and 50%, respectively, while the rates of live birth and neonatal survival were 98.7% and 98.2%, respectively. The rate of term birth was highest (70.6%) and the birth weight was heaviest (2931 ± 535g) in Group 1 (p = 0.000). In the presence of a fetus subjected to feticide, the mean delivery age was earlier than that in the non-presenting group (p = 0.017); accordingly, the mean birth weight in the feticide group was lower (2366 ± 628g) than that in the non-presenting group (2590 ± 634g) (p = 0.011). When we examined the relative relationship between reduction weeks and delivery weeks of twins by correlation analysis, we observed that with regard to maternal prognosis, two pregnancies involved preterm premature rupture of membranes (PPROM) at 7days and 3days after the procedure. Intrauterine infection occurred in two patients in Group 4, but there were no maternal deaths or maternal coagulatory abnormalities. Optimal perinatal outcomes were obtained by ST of DCDA pregnancies before 18weeks, regardless of whether or not the reduced fetus was the presenting twin. However, if legally possible, late (i.e., after 28weeks) procedures can be a safe alternative for patients diagnosed after the 18th week of gestation. Overall, we herein noted a negative correlation between the procedure week and the delivery week in this study. Moreover, ST of the non-presenting twin was associated with a heavier birth weight and later gestational age at delivery.

The effects of nutrition on mesenteric oxygenation among neonates with neonatal encephalopathy: a randomized clinical trial.

We aimed to evaluate the effects of minimal enteral nutrition (MEN) on mesenteric blood flow and oxygenation with Doppler USG and Near Infrared Spectroscopy (NIRS) during therapeutic hypothermia (TH) in babies with HIE. This prospective, randomized-controlled study was composed of infants receiving MEN (study group, n = 30) and infants who were not fed (control group, n = 30) during hypothermia. Infants were monitored continuously with NIRS and mesenteric blood flow velocities were measured with Doppler USG before and after feeding. The mean gestational age and birth weight for the study and control group were 38.73 ± 1.5-39.09 ± 1.02 weeks and 3076 ± 280.4-3295 ± 391 grams, respectively. Time to reach full enteral nutrition and hospital stay were significantly shorter in the study group (p = 0.049, p = 0.016). Infants in the study group experienced less feeding intolerance (p = 0.006). No infant developed necrotizing enterocolitis (NEC) in both groups. No difference was determined in pre- and post-feeding cerebral rSO2 measurements during TH and normothermia. Mesenteric rSO2, CSOR, and mesenteric blood flow measurements in the study group during normothermia were significantly increased, respectively (p = 0.03, p < 0.01, p < 0.01). In our study, we observed that MEN during TH does not lead to a significant change in cerebral and mesenteric oxygenation. Although we did not observe an increase in blood flow and oxygenation, the absence of NEC and a lower incidence of feeding intolerance in the study group may suggest that feeding during TH is safe and feasible. MEN during TH treatment does not lead to a significant change in cerebral and mesenteric oxygenation. This is the first study evaluating the effects of MEN on mesenteric oxygenation and blood flow velocities in infants with hypoxic-ischemic encephalopathy during TH with Doppler USG and NIRS, concomitantly. MEN during TH may be safe and feasible.

Maternal and neonatal outcomes of congenital syphilis at a tertiary care center in Turkey; a retrospective observational study

Background Maternal syphilis (MS) can lead to significant maternal morbidity and neonatal morbidity and mortality if inadequately treated. This study is aimed to retrospectively analyse the maternal and neonatal outcomes of pregnant women diagnosed with MS at our clinic. Materials and Methods We accessed the medical records of 64 cases diagnosed with MS between 2020 and 2022 from our hospital database and the perinatology clinic archives in this retrospective observational study. Case distributions by years, sociodemographic characteristics, and maternal and neonatal outcomes were recorded. Results The distribution of MS cases was 16 (25.0%) in 2020, 20 (31.25%) in 2021, and 28 (43.75%) in 2022. The mean age of the patients was 26.4 ± 6.3 years, mean BMI was 23.36 ± 3.14, the smoking rate was 31.25%, and the majority of patients were educated to primary level (37.5%). Most were housewives (43.75%), lived in urban areas (43.75%), and had lower-level incomes (68.75%). In addition, 43.75% received adequate maternal treatment, the caesarean delivery rate was 43.25%, 31.25% had preterm births, and the mean birth weight was 2956.36 + 514.46 g. CS was largely diagnosed during delivery or the postpartum period (43.75%). Fifty percent of patients were in the latent stage, gestational hypertension and preeclampsia were present in four case each (6.25%), and gestational diabetes mellitus in eight (12.5%). Twenty babies (31.25%) were admitted to the neonatal intensive care unit, eight (12.5%) had congenital anomalies, 12 had foetal growth restriction (18.25%), stillbirth was present in four (6.25%) case, and early neonatal death in four (6.25%). Conclusions Delayed diagnosis and inadequate treatment of MS can lead to significant maternal and neonatal morbidity and mortality. Well-planned antenatal care services should be provided for all expectant mothers in order to reduce these adverse outcomes.

Dysbiosis of the initial stool microbiota increases the risk of developing necrotizing enterocolitis or feeding intolerance in newborns

Several perinatal factors influence the intestinal microbiome of newborns during the first days of life, whether during delivery or even in utero. These factors may increase the risk of developing necrotizing enterocolitis (NEC) by causing dysbiosis linked to a NEC-associated microbiota, which may also be associated with other gastrointestinal problems. The objective of our study was to evaluate the potential risks associated with microbial shifts in newborns with gastrointestinal symptoms and identify the intestinal microbiota of neonates at risk for NEC.During the study period, 310 preterm and term newborns’ first passed meconium occurring within 72 h of birth were collected, and the microbiome was analyzed. We identified the risk factors in the NEC/FI group. Regarding microbiota, we compared the bacterial abundance between the NEC/FI group at the phylum and genus levels and explored the differences in the microbial composition of the 1st stool samples. A total of 14.8% (n = 46) of the infants were diagnosed with NEC or FI. In univariate analysis, the mean gestational age and birth weight were significantly lower in the NEC/FI group (p < 0.001). Prolonged rupture of membranes (PROM) > 18 h, chorioamnionitis, and histology were significantly higher in the NEC/FI group (p < 0.001). Multivariate analysis showed that gestational age (GA), prolonged membrane rupture (> 18 h), and early onset sepsis were consistently associated with an increased risk of NEC/FI. Infants diagnosed with NEC/FI exhibited a significantly lower abundance of Actinobacteria at the phylum level than the control group (p < 0.001). At the genus level, a significantly lower abundance of Streptococcus and Bifidobacterium which belong to the Actinobacteria phylum, was observed in the NEC/FI group (p < 0.001). Furthermore, the NEC/FI had significantly lower alpha diversities (Shannon Index,3.39 vs. 3.12; P = 0.044, respectively). Our study revealed that newborns with lower diversity and dysbiosis in their initial gut microbiota had an increased risk of developing NEC, with microbiota differences appearing to be associated with NEC/FI. Dysbiosis could potentially serve as a predictive marker for NEC- or GI-related symptoms.

Association between Birth Weight of the Babies and Mode of Delivery: A Cross-Sectional Study

Background: Birth weight has significant short and long-term effects on health and survival and is a useful predictor of prenatal and postnatal development. Birth weight is likely to play a key role for the infant’s survival because it is one of the strongest predictors of infant mortality risk. The aim of the study was to find out the association between birth weight and mode of delivery. Methods: This was a cross-sectional study conducted at Combined Military Hospital, Ghatail from 15 March 2019 to 30 June 2019. Secondary data were used, which were collected from hospital register during the period of 01 January 2018 to 31 December 2018. The study population was all the newborn babies delivered in CMH, Ghatail during that period and mothers of the newborn babies were respondents of the study. Results: Out of 526 respondents majority (64.83%) were in the age group of 23-32 years with mean age 25.14(range: 18-40) years. Of the newborn babies around half (48.3%) were male. The mean birth weight was 2.92 kg with minimum weight 1.2 kg and maximum 4.2 kg. The data showed that the prevalence of Low Birth Weight (LBW) 13.1%. Majority (84.6%) of the mothers didn’t have any comorbidity, few (15.4%) suffered from comorbidity. 53.8% babies were born by caesarean section (CS) and 46.2% were delivered by normal vaginal delivery. Among the low birth weight babies 65.2% were born by CS. Statistically significant association was found between birth weight of the babies and mode of delivery (p&lt;0.05). Conclusion: Caesarean section cannot be routinely recommended, unless there are other obstetric indications. Bangladesh Armed Forces Med J Vol 57 No (1) June 2024, pp 8-13

Effects of the COVID-19 pandemic on maternal-fetal outcomes in a nonepidemic designated hospital: a retrospective study and clinical experience summary

ObjectiveTo assess the changes in maternal-fetal outcomes in a nonepidemic designated hospital during the COVID-19 pandemic.MethodsThis retrospective cohort study was conducted between January 1, 2019, and December 31, 2021 on pregnant patients. The fixed-effects regression model was used to determine changes in birth outcomes and pregnancy-related complications between three periods with the pre-epidemic cohort as the control group. Logistic regression was applied to determine the odds ratio (OR) for binary outcomes.ResultsThere were 15,261 births during the pre-epidemic period, and this number decreased by 15% and 23% to 12,980 and 11,736 in the first and second epidemic cohorts, respectively. The mean birth weight during the pre-epidemic period was 3319 which decreased to 3309 and 3272 g in the following periods. Excluding stillbirth and preterm, all other outcomes differed significantly between the three periods. Gestational diabetes mellitus (GDM) (17–19%) and maternal hypertension (9.2–11%) appeared to increase. Compared to the pre-epidemic period, the odds of macrosomia and LGA significantly decreased in the second epidemic cohort (adjusted ORs: 0.76 and 0.8), while the odds of low birth weight (LBW) and small gestation age (SGA) increased (ORs: 1.25 and 1.16). The odds of neonatal asphyxia (OR: 1.4), and hypertension (OR: 1.29) appeared to increase in the second epidemic cohort, while GDM decreased in the first cohort (OR: 0.88) and increased in the second cohort (OR: 1.15). Vaginal delivery underwent a marginal decrease in both the first and second epidemic cohorts (ORs: 0.89 and 0.92).ConclusionThe COVID-19 pandemic may have had a substantial and long-term impact on non-infected pregnant women and newborns. Our research results provided precious research information and clinical experience summary for population health research in the future.

Neonatal Survival and Outcomes following Periviable Rupture of Membranes.

To clarify survival for infants affected by periviable prolonged preterm premature rupture of membranes (PPROM) in the military health system (MHS). To add to current literature on outcomes following expectant management, including long-term neurodevelopment outcomes. Retrospective matched cohort review of six level 3 military neonatal intensive care units (NICUs; 2010-2020). Cases were matched 1:1 with control infants, matched by location, gender, gestational age (within 1 week), birth weight (within 300 g), and rupture of membranes (ROM) within 24 hours of delivery. Follow-up data were obtained for each infant through 48 months' corrected age or age of last documented health visit in a military treatment facility. Forty-nine infants met inclusion criteria. Mean ROM for cohort infants was 20.7 weeks, with mean latency period of 34.6 days and mean gestational age at delivery of 25.7 weeks. Cohort infants had a mean birth weight of 919 g. Cohort survival to NICU discharge was 75.5 versus 77.6% of controls (p = 0.81). Statistically significant short-term outcomes: oligohydramnios or anhydramnios at delivery (p < 0.0001), pulmonary hypertension (p = 0.0003), and high-frequency ventilation (p = 0.004) were higher in cohort infants. No differences were found regarding rates of early sepsis, intraventricular hemorrhage, surgical necrotizing enterocolitis, oxygen at 36 weeks or at discharge. No statistical difference in long-term outcomes at 18 to 48 months of age or incidence of autism, cerebral palsy, attention deficit hyperactivity disorder, or asthma. Cohort survival to discharge in the MHS was 75.5%, higher than previously reported and not different from matched controls. Infants born after periviable PPROM should deliver at centers with access to high-frequency ventilation and ability to manage pulmonary hypertension. There was no difference in long-term neurodevelopment between the groups. · Survival to NICU discharge is similar between infants exposed to periviable PPROM and controls.. · Cohort survival to discharge was 75.5%, higher than previously reported in recent literature.. · Infant with periviable PPROM should delivery at centers capable of managing pulmonary complications..

Fetomaternal Outcome in Pregnancy with Gestational Thrombocytopenia

Introduction: Gestational thrombocytopenia, a common hematological disorder in pregnancy, poses risks to both maternal and neonatal health. This study aims to evaluate the fetomaternal outcomes in pregnancies complicated by gestational thrombocytopenia compared to those with normal platelet counts. Methods: This prospective cohort study was conducted over 12 months at Jalalabad Ragib-Rabeya Medical college hospital sylhet Bangladesh. It included 100 pregnant women diagnosed with gestational thrombocytopenia (platelet count &lt;150,000/µL after 20 weeks of gestation) and 100 matched controls with normal platelet counts. Maternal data included demographic information, obstetric and medical history, mode of delivery, incidence of pre-eclampsia, postpartum hemorrhage, and need for platelet transfusions. Fetal outcomes assessed were birth weight, Apgar scores, preterm birth rates, NICU admissions, and neonatal thrombocytopenia. Data were analyzed using t-tests for continuous variables and chi-square tests for categorical variables, with multivariate logistic regression to identify predictors of adverse outcomes. Result: The gestational thrombocytopenia group showed higher, though not statistically significant, rates of cesarean delivery (30% vs. 25%, p=0.453), pre-eclampsia (15% vs. 12%, p=0.540), and postpartum hemorrhage (18% vs. 10%, p=0.110). Platelet transfusions were required more frequently in the gestational thrombocytopenia group (8% vs. 2%, p=0.052). Fetal outcomes revealed lower mean birth weight (2950g vs. 3050g, p=0.145), higher preterm birth rates (14% vs. 10%, p=0.371), and more NICU admissions (20% vs. 12%, p=0.132) in the gestational thrombocytopenia group. Notably, neonatal thrombocytopenia was significantly more prevalent in the gestational thrombocytopenia group (10% vs. 2%, p=0.017). Conclusion: Gestational thrombocytopenia is associated with increased risks of certain maternal and neonatal complications. Vigilant monitoring and management are essential to improve outcomes in affected pregnancies. Further research is needed to develop targeted interventions and improve antenatal care practices.

Utility of the oxygenation index in management of congenital diaphragmatic hernia: a report from a Thai University Surgical Centre

BackgroundOxygenation index (OI) is associated with severity of newborn pulmonary hypertension (PH) in congenital diaphragmatic hernia (CDH). Higher OI may indicate worst degree(s) of PH.ObjectivesThis study reports OI dynamic(s) over the first 72 h of life and its correlation with (1) perioperative morbidity and (2) CDH mortality.MethodsMedical records of inborn CDH babies during 2002–2022 were examined. OI on Days (s) 1–3 and perioperative OI trends were recorded. Operation (primary vs patch repair) and survival rates (%) were studied.ResultsFifty-five CDH newborns (54.5% male: 45.5% female)—mean birth GA 37.5 ± 2.7 wks. had a mean birth weight 2813 ± 684 g with prenatal diagnosis in 32.7% cases. 52/55 (94.5%) were intubated at birth and HFOV deployed in 29 (55.8%). Those requiring HFOV had higher OI on DOL1 (24.8 ± 17 vs 10.3 ± 11.5; p < 0.05), DOL 2 (26.3 ± 22.9 vs 6.7 ± 12.1; p < 0.05) and DOL 3 (21.9 ± 33.8 vs 5.5 ± 9.3; p = 0.04). Operation was undertaken in 36/55 (65.5%). Preoperative mortality group had significant higher OI on DOL 2 (42.1 ± 21.0 vs 14.9 ± 9.3; p = 0.04). CDH defects were—Type A N = 27 (75%), Type B N = 7 (19.4%) and Type C N = 2 (5.6%). Overall mortality was 40% (22/55). Statistically significant OI trends were recorded in non-survival vs. survival groups on DOL 1 (31.6 ± 16.8. vs 10.5 ± 9.0; p < 0.05, DOL 2 (38.1 ± 21.9 vs 6.3 ± 7.1; p < 0.05), and DOL 3 (38.8 ± 39.4; p = 0.012).ConclusionsOI dynamics are highly predictive for accurate monitoring of CDH cardiorespiratory physiology and crucially may guide ventilatory management as well as timing of surgery.

Effects of intubation and hypoxemia on intraventricular hemorrhage in preterm infants during the first week: An observational study

BackgroundPreterm infants with intraventricular hemorrhage (IVH) are at a risk of developing neurodevelopmental disabilities. Few studies have examined the effects of oxygen saturation (SpO2) changes and intubation procedures on the risk of IVH. ObjectivesWe examined the effects of intubation and the rates of three thresholds of hypoxemia on the occurrence of IVH in preterm infants during their first week in the neonatal intensive care unit (NICU). MethodsIn this prospective observational cohort study, preterm infants with a gestational age (GA) of <37 weeks were included from two Level III NICUs in Taiwan. Continuous electrocardiography was used to monitor SpO2 changes, and cranial ultrasonography was used to monitor IVH. Thresholds of hypoxemia (SpO2 levels of <80 %, <85 %, and <90 %) were screened by digitally sampling data at 10-s intervals. Generalized estimating equations were used with logistic regression to analyze the effects of intubation and the rates of the three thresholds of hypoxemia on the risk of IVH during the first week after birth. ResultsIn all preterm infants (N = 73), the mean GA was 31.55 weeks, and the mean birth weight was 1508.86 g. Intubation within 3 days of birth, duration of mechanical ventilation and oxygen use, hypoxemia rate, and maternal use of magnesium sulfate before and during delivery were significantly associated with IVH. A multivariate analysis revealed that intubation was a key factor associated with the occurrence of IVH across different thresholds of hypoxemia (p = 0.004). ConclusionsAlthough the rate of hypoxemia, duration of mechanical ventilation and oxygen use, and maternal use of magnesium sulfate were significantly associated with IVH, intubation within 3 days of birth was the key factor responsible for increased IVH risk.

Trends in Retinopathy of Prematurity Among Preterm Infants in California, 2012 to 2021

The incidence of retinopathy of prematurity (ROP) has been increasing in the US since 2003. Understanding the progression of and racial disparities in ROP incidence in California can provide a contrasting perspective that may guide future research and practice in the management and prevention of ROP. To describe how the screening and incidence of ROP among very preterm infants in California changed from January 1, 2012, to December 31, 2021. This study used a cohort of very preterm infants (defined as infants born prior to 32 weeks' gestational age or weighing less than 1500 g) admitted to 60 neonatal intensive care units across California from January 1, 2012, to December 31, 2021. Among this cohort, several factors were examined, including (1) the clinical and sociodemographic covariates of the population with and without ROP, (2) trends in screening for ROP, and (3) the incidence of ROP in total and by race and ethnicity. Data analysis was performed in April 2024. Race and ethnicity and other birthing parental and infant descriptive characteristics. Incidence rates of ROP and severe ROP. The primary measures were rates of ROP screening and incidence rates of ROP and severe ROP. Time trends in the risk of ROP and severe ROP were estimated using robust Poisson regression models. In this cohort of 39 269 very preterm infants (<32 weeks' gestational age) eligible for ROP screening, the mean (SD) infant gestational age was 28.6 (2.6) weeks. The mean (SD) birth weight was 1075 (274) g, and 48.6% of infants were female. The birthing parents of the population were 12.6% Asian, 13.3% Black, 44.9% Hispanic White or Hispanic other race, 0.7% Native American/Alaskan, 24.7% non-Hispanic White, and 1.0% Pacific Islander. From January 1, 2012, to December 31, 2021, in California, ROP screening rates remained steady at 95% or greater for eligible infants less than 30 weeks of gestational age for all race and ethnic subgroups. In this study cohort among all very preterm infants (<32 weeks' gestational age), the incidence of ROP decreased from 31% in 2012 to 29% in 2021. Incidence rates of ROP among Asian and Hispanic individuals decreased the most quickly compared to other racial and ethnic groups, narrowing disparities. In this cohort study, in contrast to increasing national trends, the total incidence of and racial and ethnic disparities in ROP incidence remained steady or decreased from 2012 to 2021 in California.

A pilot randomized controlled trial comparing noradrenaline and adrenaline as a first-line vasopressor for fluid-refractory septic shock in neonates.

Limited data exists on noradrenaline therapy in neonatal septic shock. We compared the efficacy of noradrenaline with adrenaline in neonatal septic shock. This single center, open label, pilot randomized controlled trial included neonates with clinical evidence of sepsis and shock. Primary outcomes were: 1) resolution of shock one hour after treatment, and 2) mortality during hospital stay. Secondary outcomes included: need for additional vasopressors; hemodynamic stability without further administration of vasopressors for ≥2 h; changes in blood pressure and heart rate after 1 h of vasopressor treatment; and morbidities during the hospital stay. Of 65 eligible neonates, 42 were randomized (21 each in adrenaline and noradrenaline treatment arms) between August 2020 and January 2022, at level III neonatal intensive care unit (NICU) of Bharati Vidyapeeth Deemed University Medical College and Hospital (BVDUMCH). The mean (SD) gestational age and mean (SD) birth weight were 36.1(4.2) weeks and 1.8 (0.2) kilograms birth weight for noradrenaline and 36.9 (4.1) weeks and 1.7 (0.7) kilograms for adrenaline. Shock resolved within 1 h of vasopressor therapy in 76.2% neonates in the noradrenaline arm and 61.9% in adrenaline arm (p value-0.53). Mortality during hospital stay was 28.6% (6/21) in noradrenaline group and 33.3% (7/21) in adrenaline group (p value- 0.58). Additional vasopressors were required in 23.8% neonates of the noradrenaline group compared to 38.1% neonates in adrenaline arm (p value-0.53). Median (SD) duration of intensive care stay was 6 (SD) days in the noradrenaline group and 10 (SD) days in the adrenaline group (p value-0.045). Among neonates with septic shock, the efficacy of noradrenaline was comparable to adrenaline in resolving septic shock after one hour of infusion and on the mortality during hospital stay. https://ctri.nic.in/Clinicaltrials/pmaindet2.php?EncHid=NDI2NTc=&Enc=&userName=noradrenaline, Clinical Trials Registry - India with identifier CTRI/2020/08/027185 (17/08/2020).

Incidence And Risk Factors Of Retinopathy Of Prematurity: An Observational Study

Background: Retinopathy of prematurity is a condition where development of abnormal retinal vessels is secondary to an incomplete vascularization of retinal tissue due to hyperoxia, causing feedback inhibition of VEGF and destruction of endothelial cells. The risk factors of ROP should be identified to prevent disease development, and the knowledge of its etiology may help neonatologists and ophthalmologists perform careful screening and executive accurate diagnosis. In view of less literature on ROP in India, the current study was undertaken. Methods: This is a hospital-based observational study done on Neonates born at our tertiary care center- ASRAM Medical College, Eluru, Andhra Pradesh. The study was done for 6 months. Preterm infants having birth weight ≤ 1500g or gestational age ≤ 32 weeks or BW &gt; 1500g or GA between 32 to 37 weeks with either respiratory distress syndrome, or sepsis, blood transfusions, and intraventricular hemorrhage were included. Results: ROP found in 21% infants. There is no significant difference in gender, mean gestational age between two grroups. Among 21 infants with ROP, 11 had stage 1 ROP, 8 had stage 2 and 2 had stage 3 ROP. There is significant difference in mean birth weight in between two groups. Conclusion: Impaired lung function (indicating the need for usage of surfactant) which may be, caused by pneumonia, bronchopulmonary dysplasia, or hyaline membrane disease, is an important risk factor for the development of ROP. ROP needs prompt therapeutic interventions to maintain high interest at this stage

We Reduced the Incidence of Postoperative Complications in Neonatal Ostomy Patients by Using Simple Devices.

Background: Complications frequently occur after neonatal enterostomy. Enterostomy formation is a common outcome following an emergency neonatal laparotomy. This study investigated whether the incidence of complications after enterostomy could be decreased with a drainage device (composed of foreskin cerclage staple, a condom, and a 0-Mersilk braided nonabsorbable suture) fixed in the proximal ostomy bowel tube to improve proximal enterostomy in newborns. Methods: This study was a retrospective case note review of the incidence of emergency neonatal enterostomy incidence over a 3-year period (2/2016-2/2019) at the authors' center. A single surgeon conducted all surgeries. The incidence of intraoperative and postoperative complications was compared between modified and traditional surgery groups. Results: All 47 surgeries were successfully completed (32 boys and 15 girls; sex ratio: 2.13:1). The mean (±SD) birth weight, gestational period, and daily age were 2.64 ± 0.81 kg 35.62 ± 3.76 weeks and 3.49 ± 5.61 days, respectively. The patients were divided into modified surgery groups (20 cases) and traditional surgery groups (27 cases). The modified surgery group had significantly lower rates of total complications, unplanned reoperations, wound-related complications, and stoma-related complications than the traditional group (p <0.05). Conclusions: The preliminary observations suggested that the simple drainage device was a safe and effective operation device that reduced the risk of stoma-related complications.

Neonatal outcomes after in utero exposure to antipsychotics: a systematic review and meta-analysis.

Adverse neonatal outcomes following in utero antipsychotic exposure remain unclear. This systematic review and meta-analysis aimed to investigate associations between in utero first- and second-generation antipsychotic exposure and various neonatal outcomes. The primary outcome was small for gestational age. Secondary outcomes included other birth weight-related measures, prematurity and neonatal outcomes. MEDLINE, EMBASE, CENTRAL, ICTRP, and ClinicalTrials.gov were searched for on 8th July 2023. Two reviewers independently selected studies reporting associations between exposure and neonatal outcomes (all designs were eligible, no language or time restriction) and extracted data. ROBINS-I was used for risk of bias assessment. Meta-analyses were performed. Measures of association were odds ratios and mean differences. Thirty-one observational studies were included. Regarding small for gestational age < 10th percentile, meta-analysis was only performed for second-generation antipsychotics and showed no evidence for an association (OR 1.31 [95%CI 0.83; 2.07]; I²=46%; phet=0.13, n = 4 studies). First-generation antipsychotics were associated with an increased risk of small for gestational age < 3rd percentile (OR 1.37 [95%CI 1.02; 1.83]; I²=60%; phet=0.04, n = 5) and a lower mean birthweight (MD -135g [95%CI -203; -66]; I²=53%; phet=0.07, n = 5). Second-generation antipsychotics were associated with large for gestational age > 97th percentile (OR 1.56 [95%CI 1.31; 1.87]; I²=4%; phet=0.37, n = 4) and Apgar score < 7 (OR 1.64 [95%CI 1.09; 2.47]; I²=47%; phet=0.13, n = 4). Both types of antipsychotics were associated with increased risks of preterm birth and neonatal hospitalization. Despite potential confounding in the studies, this systematic review and meta-analysis showed that newborns of mothers using antipsychotics during pregnancy are potentially at risk of adverse neonatal outcomes.

Sustained decline in birth weight and increased rate of preterm infants born small for gestational age in Japan.

Birth weights have continued to decline in Japan in recent years. However, secular trend changes such as the birth weight relative to the week of gestation remain to be explored. This study aimed to determine the trends over time in mean birth weight and small for gestational age (SGA) rate for each gestational week. We used a large dataset of 27,015,792 births obtained from birth certificates between 1997 and 2021. Births from 22 to 41 weeks of gestation were evaluated in six groups (22-24, 25-27, 28-31, 32-33, 34-36, and 37-41 weeks of gestational age). For each group, secular trend changes in the z-scores calculated from standard birth weight values were assessed. Time trends in the proportion of SGA and mean birth weight z-scores were evaluated using the Cochran-Armitage trend test and linear regression analysis. Binomial logistic regression was performed to ascertain the effects of gestational age, sex, primiparity, number of births, and maternal age on the likelihood of SGA. The mean birth weight of preterm infants continued to decrease, and the z-score for mean birth weight decreased linearly, falling to -0.7 at 25-27 weeks of gestation from 1997-2001 (first period) to 2017-2021 (final period). Maternal age continued to increase from the first period to the last period for all weeks of gestation. There was a linear increase in the SGA rate in preterm infants born at <34 weeks. Odds ratios for the likelihood of SGA were 1.3 times higher for maternal age ≥40 years than that for 25-29 years (95% CI: 1.29-1.33, p < 0.001). In Japan, there has been a continuous decline in birth weight and an increase in the rate of preterm SGA infants.

Disease Burden and Outcome of Neonatal Admissions at the Tamale Teaching Hospital, Ghana: A Prospective Study

Objective: To determine the pattern of diseases and factors affecting the outcome of neonates admitted at the Tamale Teaching Hospital Neonatal Intensive Care Unit (TTH NICU) over three months. Methodology: A hospital-based prospective cohort design was used to collect data from participants. A sample size of 399 neonates (participants) admitted into the NICU from 1st March 2021 to 10th June 2021. Data was obtained using KoboCollect, exported into Excel for cleaning, coding and analysed using SPSS version 20. Results: This study screened a total of 450 neonates under 28 days admitted in the NICU of Tamale Teaching Hospital, Ghana, over three months. Fifty-one of them were rejected, and 399 were included in the final analysis. The mean birth weight was 2600 g (±810g), with 33.1% of the neonates having low birth weight. Three hundred and forty-one (341) (85.5%) neonates survived, while 58 (14.5%) died during hospitalisation. The pattern of diseases showed that neonatal sepsis (37.3%, n=149/399), small for gestational age or low birth weight (SGA/LBW) (33.1%, n=132/399), neonatal jaundice (28.1%, n=112/399), prematurity (23.6%, n=94/399), birth asphyxia (13.5%, n=54/399) and congenital anomalies (7.8%, n=31/399) were the most common causes of admissions. All variables which had an association with neonatal mortality (p &lt;0.05) were entered into a binomial logistic model, prematurity (AOR=6.974, 95% CI: 1.766-27.537; p=0.006) was the main predictor of mortality. Conclusion: The common causes of admission and deaths in the TTH NICU during the study were neonatal sepsis, prematurity, birth asphyxia, LBW/SGA and neonatal jaundice. This highlights the need for interventions to address these conditions as we strive to reduce institutional neonatal mortality.
