(Springer Nature, 2015) Bucher, Sherri; Marete, Irene; Tenge, Constance; Liechty, Edward A.; Esamai, Fabian; Patel, Archana; Goudar, Shivaprasad S.; Kodkany, Bhalchandra; Garces, Ana; Chomba, Elwyn; Althabe, Fernando; Barreuta, Mabel; Pasha, Omrana; Hibberd, Patricia; Derman, Richard J.; Otieno, Kevin; Hambidge, K. Michael; Krebs, Nancy F.; Carlo, Waldemar A.; Chemweno, Carolyne; Goldenberg, Robert L.; McClure, Elizabeth M.; Moore, Janet L.; Wallace, Dennis D.; Saleem, Sarah; Koso-Thomas, Marion; Pediatrics, School of Medicine
Background: The Global Network for Women’s and Children’s Health Research is one of the largest international networks for testing and generating evidence-based recommendations for improvement of maternal-child health in resource-limited settings. Since 2009, Global Network sites in six low and middle-income countries have collected information on antenatal care practices, which are important as indicators of care and have implications for programs to improve maternal and child health. We sought to: (1) describe the quantity of antenatal care attendance over a four-year period; and (2) explore the quality of coverage for selected preventative, screening, and birth preparedness components. Methods: The Maternal Newborn Health Registry (MNHR) is a prospective, population-based birth and pregnancy outcomes registry in Global Network sites, including: Argentina, Guatemala, India (Belgaum and Nagpur), Kenya, Pakistan, and Zambia. MNHR data from these sites were prospectively collected from January 1, 2010 – December 31, 2013 and analyzed for indicators related to quantity and patterns of ANC and coverage of key elements of recommended focused antenatal care. Descriptive statistics were generated overall by global region (Africa, Asia, and Latin America), and for each individual site. Results: Overall, 96% of women reported at least one antenatal care visit. Indian sites demonstrated the highest percentage of women who initiated antenatal care during the first trimester. Women from the Latin American and Indian sites reported the highest number of at least 4 visits. Overall, 88% of women received tetanus toxoid. Only about half of all women reported having been screened for syphilis (49%) or anemia (50%). Rates of HIV testing were above 95% in the Argentina, African, and Indian sites. The Pakistan site demonstrated relatively high rates for birth preparation, but for most other preventative and screening interventions, posted lower coverage rates as compared to other Global Network sites. Conclusions: Results from our large, prospective, population-based observational study contribute important insight into regional and site-specific patterns for antenatal care access and coverage. Our findings indicate a quality and coverage gap in antenatal care services, particularly in regards to syphilis and hemoglobin screening. We have identified site-specific gaps in access to, and delivery of, antenatal care services that can be targeted for improvement in future research and implementation efforts.
Association of hemoglobin levels in the first trimester and at 26 to 30 weeks with fetal and neonatal outcomes: A secondary analyses of the Global Network for Women’s and Children’s Health’s ASPIRIN Trial
(Wiley, 2021) Jessani, Saleem; Saleem, Sarah; Hoffman, Matthew K.; Goudar, Shivaprasad S.; Derman, Richard J.; Moore, Janet L.; Garces, Ana; Figueroa, Lester; Krebs, Nancy F.; Okitawutshu, Jean; Tshefu, Antoinette; Bose, Carl L.; Mwenechanya, Musaku; Chomba, Elwyn; Carlo, Waldemar A.; Das, Prabir Kumar; Patel, Archana; Hibberd, Patricia L.; Esamai, Fabian; Liechty, Edward A.; Bucher, Sherri; Nolen, Tracy L.; Koso-Thomas, Marion; Miodovnik, Menachem; McClure, Elizabeth M.; Goldenberg, Robert L.; Social and Behavioral Sciences, School of Public Health
Objective: Limited data are available from low- and middle-income countries (LMICs) on the relationship of haemoglobin levels to adverse outcomes at different times during pregnancy. We evaluated the association of haemoglobin levels in nulliparous women at two times in pregnancy with pregnancy outcomes. Design: ASPIRIN Trial data were used to study the association between haemoglobin levels measured at 6+0 -13+6 weeks and 26+0 -30+0 weeks of gestation with fetal and neonatal outcomes. Setting: Obstetric care facilities in Pakistan, India, Kenya, Zambia, The Democratic Republic of the Congo and Guatemala. Population: A total of 11 976 pregnant women. Methods: Generalised linear models were used to obtain adjusted relative risks and 95% CI for adverse outcomes. Main outcome measures: Preterm birth, stillbirth, neonatal death, small for gestational age (SGA) and birthweight <2500 g. Results: The mean haemoglobin levels at 6+0 -13+6 weeks and at 26-30 weeks of gestation were 116 g/l (SD 17) and 107 g/l (SD 15), respectively. In general, pregnancy outcomes were better with increasing haemoglobin. At 6+0 -13+6 weeks of gestation, stillbirth, SGA and birthweight <2500 g, were significantly associated with haemoglobin of 70-89 g/l compared with haemoglobin of 110-129 g/l The relationships of adverse pregnancy outcomes with various haemoglobin levels were more marked at 26-30 weeks of gestation. Conclusions: Both lower and some higher haemoglobin concentrations are associated with adverse fetal and neonatal outcomes at 6+0 -13+6 weeks and at 26-30 weeks of gestation, although the relationship with low haemoglobin levels appears more consistent and generally stronger.
Azithromycin to Prevent Sepsis or Death in Women Planning a Vaginal Birth
(Massachusetts Medical Society, 2023) Tita, Alan T. N.; Carlo, Waldemar A.; McClure, Elizabeth M.; Mwenechanya, Musaku; Chomba, Elwyn; Hemingway-Foday, Jennifer J.; Kavi, Avinash; Metgud, Mrityunjay C.; Goudar, Shivaprasad S.; Derman, Richard; Lokangaka, Adrien; Tshefu, Antoinette; Bauserman, Melissa; Bose, Carl; Shivkumar, Poonam; Waikar, Manju; Patel, Archana; Hibberd, Patricia L.; Nyongesa, Paul; Esamai, Fabian; Ekhaguere, Osayame A.; Bucher, Sherri; Jessani, Saleem; Tikmani, Shiyam S.; Saleem, Sarah; Goldenberg, Robert L.; Billah, Sk M.; Lennox, Ruth; Haque, Rashidul; Petri, William; Figueroa, Lester; Mazariegos, Manolo; Krebs, Nancy F.; Moore, Janet L.; Nolen, Tracy L.; Koso-Thomas, Marion; A-PLUS Trial Group; Pediatrics, School of Medicine
Background: The use of azithromycin reduces maternal infection in women during unplanned cesarean delivery, but its effect on those with planned vaginal delivery is unknown. Data are needed on whether an intrapartum oral dose of azithromycin would reduce maternal and offspring sepsis or death. Methods: In this multicountry, placebo-controlled, randomized trial, we assigned women who were in labor at 28 weeks' gestation or more and who were planning a vaginal delivery to receive a single 2-g oral dose of azithromycin or placebo. The two primary outcomes were a composite of maternal sepsis or death and a composite of stillbirth or neonatal death or sepsis. During an interim analysis, the data and safety monitoring committee recommended stopping the trial for maternal benefit. Results: A total of 29,278 women underwent randomization. The incidence of maternal sepsis or death was lower in the azithromycin group than in the placebo group (1.6% vs. 2.4%), with a relative risk of 0.67 (95% confidence interval [CI], 0.56 to 0.79; P<0.001), but the incidence of stillbirth or neonatal death or sepsis was similar (10.5% vs. 10.3%), with a relative risk of 1.02 (95% CI, 0.95 to 1.09; P = 0.56). The difference in the maternal primary outcome appeared to be driven mainly by the incidence of sepsis (1.5% in the azithromycin group and 2.3% in the placebo group), with a relative risk of 0.65 (95% CI, 0.55 to 0.77); the incidence of death from any cause was 0.1% in the two groups (relative risk, 1.23; 95% CI, 0.51 to 2.97). Neonatal sepsis occurred in 9.8% and 9.6% of the infants, respectively (relative risk, 1.03; 95% CI, 0.96 to 1.10). The incidence of stillbirth was 0.4% in the two groups (relative risk, 1.06; 95% CI, 0.74 to 1.53); neonatal death within 4 weeks after birth occurred in 1.5% in both groups (relative risk, 1.03; 95% CI, 0.86 to 1.24). Azithromycin was not associated with a higher incidence in adverse events. Conclusions: Among women planning a vaginal delivery, a single oral dose of azithromycin resulted in a significantly lower risk of maternal sepsis or death than placebo but had little effect on newborn sepsis or death.
Birth weight and gestational age distributions in a rural Kenyan population
(Springer Nature, 2023-03-08) Bucher, Sherri; Nowak, Kayla; Otieno, Kevin; Tenge, Constance; Rutto, Faith; Kemboi, Millsort; Achieng, Emmah; Ekhaguere, Osayame A.; Nyongesa, Paul; Esamai, Fabian O.; Liechty, Edward A.; Pediatrics, School of Medicine
Background: With the increased availability of access to prenatal ultrasound in low/middle-income countries, there is opportunity to better characterize the association between fetal growth and birth weight across global settings. This is important, as fetal growth curves and birthweight charts are often used as proxy health indicators. As part of a randomized control trial, in which ultrasonography was utilized to establish accurate gestational age of pregnancies, we explored the association between gestational age and birthweight among a cohort in Western Kenya, then compared our results to data reported by the INTERGROWTH-21st study. Methods: This study was conducted in 8 geographical clusters across 3 counties in Western Kenya. Eligible subjects were nulliparous women carrying singleton pregnancies. An early ultrasound was performed between 6 + 0/7 and 13 + 6/7 weeks gestational age. At birth, infants were weighed on platform scales provided either by the study team (community births), or the Government of Kenya (public health facilities). The 10th, 25th, median, 75th, and 90th BW percentiles for 36 to 42 weeks gestation were determined; resulting percentile points were plotted, and curves determined using a cubic spline technique. A signed rank test was used to quantify the comparison of the percentiles generated in the rural Kenyan sample with those of the INTERGROWTH-21st study. Results: A total of 1291 infants (of 1408 pregnant women randomized) were included. Ninety-three infants did not have a measured birth weight. The majority of these were due to miscarriage (n = 49) or stillbirth (n = 27). No significant differences were found between subjects who were lost to follow-up. Signed rank comparisons of the observed median of the Western Kenya data at 10th, 50th, and 90th birthweight percentiles, as compared to medians reported in the INTERGROWTH-21st distributions, revealed close alignment between the two datasets, with significant differences at 36 and 37 weeks. Limitations of the current study include small sample size, and detection of potential digit preference bias. Conclusions: A comparison of birthweight percentiles by gestational age estimation, among a sample of infants from rural Kenya, revealed slight differences as compared to those from the global population.
Caesarean birth by maternal request: a poorly understood phenomenon in low- and middle-income countries
(Oxford University Press, 2021-01-14) Harrison, Margo S.; Garces, Ana; Figueroa, Lester; Esamai, Fabian; Bucher, Sherri; Bose, Carl; Goudar, Shivaprasad; Derman, Richard; Patel, Archana; Hibberd, Patricia L.; Chomba, Elwyn; Mwenechanya, Miusaku; Hambidge, Michael; Krebs, Nancy F.; Medicine, School of Medicine
Background: While trends in caesarean birth by maternal request in low- and middle-income countries are unclear, age, education, multiple gestation and hypertensive disease appear associated with the indication when compared with caesarean birth performed for medical indications. Methods: We performed a secondary analysis of a prospectively collected population-based study of home and facility births using descriptive statistics, bivariate comparisons and multilevel mixed-effects logistic regression. Results: Of 28 751 patients who underwent caesarean birth and had a documented primary indication for the surgery, 655 (2%) were attributed to caesarean birth by maternal request. The remaining 98% were attributed to maternal and foetal indications and prior caesarean birth. In a multilevel mixed effects logistic regression adjusted for site and cluster of birth, when compared with caesareans performed for medical indications, caesarean birth performed for maternal request had a higher odds of being performed among women ≥35 y of age, with a university or higher level of education, with multiple gestations and with pregnancies complicated by hypertension (P < 0.01). Caesarean birth by maternal request was associated with a two-times increased odds of breastfeeding within 1 h of delivery, but no adverse outcomes (when compared with women who underwent caesarean birth for medical indications; P < 0.01). Conclusion: Caesarean performed by maternal request is more common in older and more educated women and those with multifoetal gestation or hypertensive disease. It is also associated with higher rates of breastfeeding within 1 h of delivery.
Can the date of last menstrual period be trusted in the first trimester? Comparisons of gestational age measures from a prospective cohort study in six low-income to middle-income countries
(BMJ, 2023-09-20) Patel, Archana; Bann, Carla M.; Thorsten, Vanessa R.; Rao, Sowmya R.; Lokangaka, Adrien; Tshefu Kitoto, Antoinette; Bauserman, Melissa; Figueroa, Lester; Krebs, Nancy F.; Esamai, Fabian; Bucher, Sherri; Saleem, Sarah; Goldenberg, Robert L.; Chomba, Elwyn; Carlo, Waldemar A.; Goudar, Shivaprasad; Derman, Richard; Koso-Thomas, Marion; McClure, Elizabeth; Hibberd, Patricia L.; Pediatrics, School of Medicine
Objectives: We examined gestational age (GA) estimates for live and still births, and prematurity rates based on last menstrual period (LMP) compared with ultrasonography (USG) among pregnant women at seven sites in six low-resource countries. Design: Prospective cohort study SETTING AND PARTICIPANTS: This study included data from the Global Network's population-based Maternal and Newborn Health Registry which follows pregnant women in six low-income and middle-income countries (Democratic Republic of the Congo, Guatemala, India, Kenya, Pakistan and Zambia). Participants in this analysis were 42 803 women, including their 43 230 babies, who registered for the study in their first trimester based on GA estimated either by LMP or USG and had a live or stillbirth with an estimated GA of 20-42 weeks. Outcome measures: GA was estimated in weeks and days based on LMP and/or USG. Prematurity was defined as GA of 20 weeks+0 days through 36 weeks+6 days, calculated by both USG and LMP. Results: Overall, average GA varied ≤1 week between LMP and USG. Mean GA for live births by LMP was lower than by USG (adjusted mean difference (95% CI) = -0.23 (-0.29 to -0.17) weeks). Among stillbirths, a higher GA was estimated by LMP than USG (adjusted mean difference (95% CI)= 0.42 (0.11 to 0.72) weeks). Preterm birth rates for live births were significantly higher when dated by LMP (adjusted rate difference (95% CI)= 4.20 (3.56 to 4.85)). There was no significant difference in preterm birth rates for stillbirths. Conclusion: The small differences in GA for LMP versus USG in the Guatemalan and Indian sites suggest that LMP may be a useful alternative to USG for GA dating during the first trimester until availability of USG improves in those areas. Further research is needed to assess LMP for first-trimester GA dating in other regions with limited access to USG.
Community based weighing of newborns and use of mobile phones by village elders in rural settings in Kenya: a decentralised approach to health care provision
(Springer Nature, 2012-03-19) Gisore, Peter; Shipala, Evelyn; Otieno, Kevin; Rono, Betsy; Marete, Irene; Tenge, Constance; Mabeya, Hillary; Bucher, Sherri; Moore, Janet; Liechty, Edward; Esamai, Fabian; Pediatrics, School of Medicine
Background: Identifying every pregnancy, regardless of home or health facility delivery, is crucial to accurately estimating maternal and neonatal mortality. Furthermore, obtaining birth weights and other anthropometric measurements in rural settings in resource limited countries is a difficult challenge. Unfortunately for the majority of infants born outside of a health care facility, pregnancies are often not recorded and birth weights are not accurately known. Data from the initial 6 months of the Maternal and Neonatal Health (MNH) Registry Study of the Global Network for Women and Children's Health study area in Kenya revealed that up to 70% of newborns did not have exact weights measured and recorded by the end of the first week of life; nearly all of these infants were born outside health facilities. Methods: To more completely obtain accurate birth weights for all infants, regardless of delivery site, village elders were engaged to assist in case finding for pregnancies and births. All elders were provided with weighing scales and mobile phones as tools to assist in subject enrollment and data recording. Subjects were instructed to bring the newborn infant to the home of the elder as soon as possible after birth for weight measurement.The proportion of pregnancies identified before delivery and the proportion of births with weights measured were compared before and after provision of weighing scales and mobile phones to village elders. Primary outcomes were the percent of infants with a measured birth weight (recorded within 7 days of birth) and the percent of women enrolled before delivery. Results: The recorded birth weight increased from 43 ± 5.7% to 97 ± 1.1. The birth weight distributions between infants born and weighed in a health facility and those born at home and weighed by village elders were similar. In addition, a significant increase in the percent of subjects enrolled before delivery was found. Conclusions: Pregnancy case finding and acquisition of birth weight information can be successfully shifted to the community level.

Cost-effectiveness of low-dose aspirin for the prevention of preterm birth: a prospective study of the Global Network for Women's and Children's Health Research
(Elsevier, 2023) Patterson, Jackie K.; Neuwahl, Simon; Goco, Norman; Moore, Janet; Goudar, Shivaprasad S.; Derman, Richard J.; Hoffman, Matthew; Metgud, Mrityunjay; Somannavar, Manjunath; Kavi, Avinash; Okitawutshu, Jean; Lokangaka, Adrien; Tshefu, Antoinette; Bose, Carl L.; Mwapule, Abigail; Mwenechanya, Musaku; Chomba, Elwyn; Carlo, Waldemar A.; Chicuy, Javier; Figueroa, Lester; Krebs, Nancy F.; Jessani, Saleem; Saleem, Sarah; Goldenberg, Robert L.; Kurhe, Kunal; Das, Prabir; Patel, Archana; Hibberd, Patricia L.; Achieng, Emmah; Nyongesa, Paul; Esamai, Fabian; Bucher, Sherri; Liechty, Edward A.; Bresnahan, Brian W.; Koso-Thomas, Marion; McClure, Elizabeth M.; Pediatrics, School of Medicine
Background: Premature birth is associated with an increased risk of mortality and morbidity, and strategies to prevent preterm birth are few in number and resource intensive. In 2020, the ASPIRIN trial showed the efficacy of low-dose aspirin (LDA) in nulliparous, singleton pregnancies for the prevention of preterm birth. We sought to investigate the cost-effectiveness of this therapy in low-income and middle-income countries. Methods: In this post-hoc, prospective, cost-effectiveness study, we constructed a probabilistic decision tree model to compare the benefits and costs of LDA treatment compared with standard care using primary data and published results from the ASPIRIN trial. In this analysis from a health-care sector perspective, we considered the costs and effects of LDA treatment, pregnancy outcomes, and neonatal health-care use. We did sensitivity analyses to understand the effect of the price of the LDA regimen, and the effectiveness of LDA in reducing both preterm birth and perinatal death. Findings: In model simulations, LDA was associated with 141 averted preterm births, 74 averted perinatal deaths, and 31 averted hospitalisations per 10 000 pregnancies. The reduction in hospitalisation resulted in a cost of US$248 per averted preterm birth, $471 per averted perinatal death, and $15·95 per disability-adjusted life year. Interpretation: LDA treatment in nulliparous, singleton pregnancies is a low-cost, effective treatment to reduce preterm birth and perinatal death. The low cost per disability-adjusted life year averted strengthens the evidence in support of prioritising the implementation of LDA in publicly funded health care in low-income and middle-income countries.
Critical Interpretive Synthesis of Qualitative Data on the Health Care Ecosystem for Vulnerable Newborns in Low- to Middle-Income Countries
(Elsevier, 2021-09) Ray, Hannah; Sobiech, Kathleen L.; Alexandrova, Maria; Songok, Julia Jerono; Rukunga, Janet; Bucher, Sherri; Pediatrics, School of Medicine
OBJECTIVE: To critically assess and synthesize qualitative findings regarding the health care ecosystem for vulnerable (low-birth-weight or sick) neonates in low- to middle-income countries (LMICs). DATA SOURCES: Between May 4 and June 2, 2020, we searched four databases (Medline [PubMed], SCOPUS, PsycINFO, and Web of Science) for articles published from 2010 to 2020. Inclusion criteria were peer-reviewed reports of original studies focused on the health care ecosystem for vulnerable neonates in LMICs. We also searched the websites of several international development agencies and included findings from primary data collected between May and July 2019 at a tertiary hospital in Kenya. We excluded studies and reports if the focus was on healthy neonates or high-income countries and if they contained only quantitative data, were written in a language other than English, or were published before 2010. STUDY SELECTION: One of the primary authors conducted an initial review of titles and abstracts (n = 102) and excluded studies that were not consistent with the purpose of the review (n = 60). The two primary authors used a qualitative appraisal checklist to assess the validity of the remaining studies (n = 42) and reached agreement on the final 13 articles. DATA EXTRACTION: The two primary authors independently conducted open and axial coding of the data. We incorporated data from studies with different units of analysis, types of methodology, research topics, participant types, and analytical frameworks in an emergent conceptual development process according to the critical interpretive synthesis methodology. DATA SYNTHESIS: We synthesized our findings into one overarching theme, Pervasive Turbulence Is a Defining Characteristic of the Health Care Ecosystem in LMICs, and two subthemes: Pervasive Turbulence May Cause Tension Between the Setting and the Caregiver and Pervasive Turbulence May Result in a Loss of Synergy in the Caregiver-Parent Relationship. CONCLUSION: Because pervasive turbulence characterizes the health care ecosystems in LMICs, interventions are needed to support the caregiver-parent interaction to mitigate the effects of tension in the setting.
