Abstract
OBJECTIVES To investigate the risk factors for bronchopulmonary dysplasia (BPD) in twin preterm infants with a gestational age of <34 weeks, and to provide a basis for early identification of BPD in twin preterm infants in clinical practice. METHODS A retrospective analysis was performed for the twin preterm infants with a gestational age of <34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020. According to their conditions, they were divided into group A (both twins had BPD), group B (only one twin had BPD), and group C (neither twin had BPD). The risk factors for BPD in twin preterm infants were analyzed. Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins. RESULTS A total of 904 pairs of twins with a gestational age of <34 weeks were included in this study. The multivariate logistic regression analysis showed that compared with group C, birth weight discordance of >25% between the twins was an independent risk factor for BPD in one of the twins (OR=3.370, 95%CI: 1.500-7.568, P<0.05), and high gestational age at birth was a protective factor against BPD (P<0.05). The conditional logistic regression analysis of group B showed that small-for-gestational-age (SGA) birth was an independent risk factor for BPD in individual twins (OR=5.017, 95%CI: 1.040-24.190, P<0.05). CONCLUSIONS The development of BPD in twin preterm infants is associated with gestational age, birth weight discordance between the twins, and SGA birth.

Prevalence and adverse outcomes of twin pregnancy in Eastern Africa: a systematic review and meta-analysis. BMC Pregnancy Childbirth 2024; 24:169. [PMID: 38424482 PMCID: PMC10905881 DOI: 10.1186/s12884-024-06326-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 02/06/2024] [Indexed: 03/02/2024] Open
Abstract
INTRODUCTION Multiple pregnancies are much more common today than they were in the past. Twin pregnancies occur in about 4% of pregnancies in Africa. Adverse pregnancy outcome was more common in twin pregnancy than in singleton pregnancy. There is no pooled evidence on the burden and adverse pregnancy outcome of twin pregnancy in eastern Africa. Thus, this systematic review and meta-analysis were conducted to assess the prevalence and adverse pregnancy outcomes of twin pregnancies. METHODS This systematic review and meta-analysis covers published and unpublished studies searched from different databases (PubMed, CINAHL (EBSCO), EMBASE, DOAJ, Web of Sciences, MEDLINE, Cochrane Library, SCOPUS, Google Scholar, and Google search). Finally, 34 studies were included in this systematic review and meta-analysis. JBI checklist was used to assess the quality of included papers. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Data synthesis and statistical analysis were conducted using STATA Version 14 software. Heterogeneity and publication bias were assessed. A forest plot was used to present the pooled prevalence using the random effect model. RESULTS The prevalence of twin pregnancy in eastern Africa was 3% [95% CI: 2, 3]. The adverse pregnancy outcomes like neonatal intensive care unit admission (78%), low birth weight (44%), low APGAR score (33%), prematurity (32%), stillbirth (30%), neonatal mortality (12%) and maternal complications like hypertensive disorder of pregnancy (25%), postpartum hemorrhage (7%), Cesarean section (37%), premature rupture of membrane (12%) and maternal mortality are more common among twin pregnancy than singleton pregnancy. CONCLUSION One in every 33 children born a twin in east Africa; admission to neonatal intensive care unit, low birth weight, low APGAR score, prematurity, stillbirth, neonatal mortality and maternal complications are its associated adverse birth outcomes. Since twin pregnancy is a high-risk pregnancy, special care is needed during pregnancy, labor and delivery to reduce adverse pregnancy outcomes.

Abstract
BACKGROUND Sub-Saharan African (SSA) countries have high stillbirth rates compared with high-income countries, yet research on risk factors for stillbirth in SSA remain scant. OBJECTIVES To identify the modifiable risk factors of stillbirths in SSA and investigate their strength of association using a systematic review. SEARCH STRATEGY CINAHL Plus, EMBASE, Global Health and MEDLINE databases were searched for literature. SELECTION CRITERIA Observational population- and facility-level studies exploring stillbirth risk factors, published in 2013-2019 were included. DATA COLLECTION AND ANALYSIS A narrative synthesis of data was undertaken and the potential risk factors were classified into subgroups. MAIN RESULTS Thirty-seven studies were included, encompassing 20 264 stillbirths. The risk factors were categorised as: maternal antepartum factors (0-4 antenatal care visits, multiple gestations, hypertension, birth interval of >3 years, history of perinatal death); socio-economic factors (maternal lower wealth index and basic education, advanced maternal age, grand multiparity of ≥5); intrapartum factors (direct obstetric complication); fetal factors (low birthweight and gestational age of <37 weeks) and health systems factors (poor quality of antenatal care, emergency referrals, ill-equipped facility). The proportion of unexplained stillbirths remained very high. No association was found between stillbirths and body mass index, diabetes, distance from the facility or HIV. CONCLUSIONS The overall quality of evidence was low, as many studies were facility based and did not adjust for confounding factors. This review identified preventable risk factors for stillbirth. Focused programmatic strategies to improve antenatal care, emergency obstetric care, maternal perinatal education, referral and outreach systems, and birth attendant training should be developed. More population-based, high-quality research is needed.

The impact of free antiretroviral therapy for pregnant non-citizens and their infants in Botswana. J Int AIDS Soc 2023; 26:e26161. [PMID: 37885157 PMCID: PMC10603275 DOI: 10.1002/jia2.26161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Accepted: 08/21/2023] [Indexed: 10/28/2023] Open
Abstract
INTRODUCTION In December 2019, the Botswana government expanded free antiretroviral therapy (ART) to include non-citizens. We evaluated the impact of this policy change on antenatal care (ANC), antiretroviral therapy coverage and adverse birth outcomes. METHODS The Tsepamo Surveillance study collects data at up to 18 delivery sites in Botswana. We compared outcomes in citizens and non-citizens living with HIV before and after antiretroviral therapy expansion to non-citizens. Adverse birth outcomes included preterm delivery (PTD) <37 weeks, very preterm delivery (VPTD) <32 weeks, small for gestational age (SGA) <10th percentile, very small for gestational age (VSGA) <3rd percentile, stillbirth and neonatal death. Log-binomial regression models were constructed to generate risk ratios. RESULTS From August 2014 to September 2021, 45,576 (96.5%) citizens and 1513 (3.2%) non-citizens living with HIV delivered; 954 (62.9%) non-citizen deliveries were before the antiretroviral therapy expansion, and 562 (37.1%) were after. Non-citizen ANC attendance among pregnant people living with HIV increased from 79.2% pre-expansion to 87.2% post-expansion (p<0.001), and became more similar to citizens (96.0% post-expansion). Non-citizens receiving any antenatal antiretroviral therapy increased from 65.5% pre-expansion to 89.9% post-expansion (p < 0.001), also more similar to citizens (97.2% post-expansion). Infants born to non-citizens with singleton gestations in the pre-expansion period had significantly greater risk of PTD (aRR = 1.28, 95% CI, 1.11, 1.46), VPTD (aRR = 1.89, 95% CI, 1.43, 2.44) and neonatal death (aRR = 1.69, 95% CI, 1.03, 2.60), but reduced SGA risk (aRR = 0.75; 95% CI, 0.62, 0.89) compared with citizens. Post-expansion, greater declines in most adverse outcomes were observed in non-citizens, with largely similar outcomes between non-citizens and citizens. Non-significant differences were observed for non-citizenship in PTD (aRR = 0.84, 95% CI, 0.66, 1.06), VPTD (aRR = 0.57, 95% CI, 0.28, 1.01), SGA (aRR = 0.91, 95% CI, 0.72, 1.13), VSGA (aRR = 0.87, 95% CI, 0.58, 1.25), stillbirth (aRR = 0.71, 95% CI, 0.35, 1.27) and neonatal death (aRR = 1.35, 95% CI, 0.60, 2.62). CONCLUSIONS Following the expansion of free antiretroviral therapy to non-citizens, gaps narrowed in ANC and antiretroviral therapy use in pregnancy between citizens and non-citizens living with HIV. Disparities in adverse birth outcomes were no longer observed.

Perinatal characteristics and neonatal outcomes of singletons and twins in Chinese very preterm infants: a cohort study. BMC Pregnancy Childbirth 2023; 23:89. [PMID: 36726075 PMCID: PMC9890855 DOI: 10.1186/s12884-023-05409-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Accepted: 01/25/2023] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND The prevalence of preterm birth has been rising, and there is a paucity of nationwide data on the perinatal characteristics and neonatal outcomes of twin deliveries of very preterm infants (VPIs) in China. This study compared the perinatal characteristics and outcomes of singletons and twins admitted to neonatal intensive care units (NICUs) in China. METHODS The study population comprised all infants born before 32 weeks in the Chinese Neonatal Network (CHNN) between January 2019 and December 2019. Three-level and population-average generalized estimating equation (GEE)/alternating logistic regression (ALR) models were used to determine the association of twins with neonatal morbidities and the use of NICU resources. RESULTS During the study period, there were 6634 (71.2%) singletons and 2680 (28.8%) twins, with mean birth weights of 1333.70 g and 1294.63 g, respectively. Twins were significantly more likely to be delivered by caesarean section (p < 0.01), have antenatal steroid usage (p = 0.048), have been conceived by assisted reproductive technology (ART) (p < 0.01), have a higher prevalence of maternal diabetes (p < 0.01) and be inborn (p < 0.01) than singletons. In addition, twins had a lower prevalence of small for gestational age, maternal hypertension, and primigravida mothers than singletons (all p < 0.01). After adjusting for potential confounders, twins had higher mortality rates (adjusted odds ratio [AOR] 1.28, 95% confidence interval [CI] 1.10-1.49), higher incidences of short-term composite outcomes (AOR 1.28, 95% CI 1.09-1.50), respiratory distress syndrome (RDS) (AOR 1.30, 95% CI 1.12-1.50), and bronchopulmonary dysplasia (BPD) (AOR 1.10, 95% CI 1.01-1.21), more surfactant usage (AOR 1.22, 95% CI 1.05-1.41) and prolonged hospital stays (adjusted mean ratio 1.03, 95% CI 1.00-1.06), compared to singletons. CONCLUSION Our work suggests that twins have a greater risk of mortality, a higher incidence of RDS and BPD, more surfactant usage, and longer NICU stays than singletons among VPIs in China.

Abstract
To investigate the relationship between abnormal umbilical cord insertion and birthweight discordance in monochorionic diamnionic (MCDA) twins. A total of 137 pairs of MCDAs were retrospectively analyzed who delivered and survived in Hangzhou Women's Hospital from January 2016 to December 2021. According to different insertion methods, they were divided into normal cord insertion group (n = 57), marginal cord insertion (MCI) group (n = 34) and velamentous cord insertion (VCI) group (n = 46). The correlation was analyzed between different insertion methods of umbilical cord and the discordant birth weight of MCDAs. The gestational age of delivery with velamentous cord insertion was significantly earlier than those with normal and marginal insertion (P < .05). There were significant differences in birthweight between large fetus (F1) and small fetus (F2) with different umbilical insertion methods (P < .05). The birthweight of F1 and F2 in normal insertion group was significantly higher than those in MCI and VCI group (P < .05). Logistic regression analysis showed that VCI was significantly associated with birth weight in F1/F2, birthweight discordance ≥ 20%, and birthweight discordance ≥ 25%, however MCI and VCI were not an independent factor for discordance in birthweight of MCDAs (P > .05). Umbilical cord insertion method can lead to inconsistency in birthweight of MCDA twins, however they were not an independent factor for discordance in birthweight.
