Item 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 MedicineBackground: 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.Item Corrigendum to The impact of risk factors on aspirin's efficacy for the prevention of preterm birth. American Journal of Obstetrics & Gynecology MFM. Volume 5, Issue 10, October 2023, 101095(Elsevier, 2024) Nuss, Emily E.; Hoffman, Matthew K.; Goudar, Shivaprasad S.; Kavi, Avinash; Metgud, Mrityunjay; Somannavar, Manjunath; Okitawutshu, Jean; Lokangaka, Adrien; Tshefu, Antoinette; Bauserman, Melissa; Tembo, Abigail Mwapule; Chomba, Elwyn; Carlo, Waldemar A.; Figueroa, Lester; Krebs, Nancy F.; Jessani, Saleem; Saleem, Sarah; Goldenberg, Robert L.; Kurhe, Kunal; Das, Prabir; Hibberd, Patricia L.; Achieng, Emmah; Nyongesa, Paul; Esamai, Fabian; Liechty, Edward A.; Bucher, Sherri; Goco, Norman; Hemingway-Foday, Jennifer; Moore, Janet; McClure, Elizabeth M.; Silver, Robert M.; Derman, Richard J.; Patel, Archana; Aspirin Supplementation for Pregnancy Indicated Risk Reduction In Nulliparas Study Group; Pediatrics, School of MedicineThe authors regret that the originally published manuscript erroneously excluded a contributing author Archana Patel MD, PhD.

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.Item Knowledge, attitudes, and practices of pregnant women regarding COVID-19 vaccination in pregnancy in 7 low- and middle-income countries: An observational trial from the Global Network for Women and Children's Health Research(Wiley, 2022-11) Naqvi, Seemab; Saleem, Sarah; Naqvi, Farnaz; Billah, Sk Masum; Nielsen, Eleanor; Fogleman, Elizabeth; Peres-da-Silva, Nalini; Figueroa, Lester; Mazariegos, Manolo; Garces, Ana L.; Patel, Archana; Das, Prabir; Kavi, Avinash; Goudar, Shivaprasad S.; Esamai, Fabian; Chomba, Elwyn; Lokangaka, Adrien; Tshefu, Antoinette; Haque, Rashidul; Siraj, Shahjahan; Yousaf, Sana; Bauserman, Melissa; Liechty, Edward A.; Krebs, Nancy F.; Derman, Richard J.; Carlo, Waldemar A.; Petri, William A., Jr.; Hibberd, Patricia L.; Koso-Thomas, Marion; Thorsten, Vanessa; McClure, Elizabeth M.; Goldenberg, Robert L.; Pediatrics, School of MedicineObjectives: We sought to determine the knowledge, attitudes and practices of pregnant women regarding COVID-19 vaccination in pregnancy in seven low- and middle-income countries (LMIC). Design: Prospective, observational, population-based study. Settings: Study areas in seven LMICs: Bangladesh, India, Pakistan, Guatemala, Democratic Republic of the Congo (DRC), Kenya and Zambia. Population: Pregnant women in an ongoing registry. Methods: COVID-19 vaccine questionnaires were administered to pregnant women in the Global Network's Maternal Newborn Health Registry from February 2021 through November 2021 in face-to-face interviews. Main outcome measures: Knowledge, attitude and practice regarding vaccination during pregnancy; vaccination status. Results: No women were vaccinated except for small proportions in India (12.9%) and Guatemala (5.5%). Overall, nearly half the women believed the COVID-19 vaccine is very/somewhat effective and a similar proportion believed that the COVID-19 vaccine is safe for pregnant women. With availability of vaccines, about 56.7% said they would get the vaccine and a 34.8% would refuse. Of those who would not get vaccinated, safety, fear of adverse effects, and lack of trust predicted vaccine refusal. Those with lower educational status were less willing to be vaccinated. Family members and health professionals were the most trusted source of information for vaccination. Conclusions: This COVID-19 vaccine survey in seven LMICs found that knowledge about the effectiveness and safety of the vaccine was generally low but varied. Concerns about vaccine safety and effectiveness among pregnant women is an important target for educational efforts to increase vaccination rates.Item Safety of daily low-dose aspirin use during pregnancy in low-income and middle-income countries(Elsevier, 2021) Short, Vanessa L.; Hoffman, Matthew; Metgud, Mrityunjay; Kavi, Avinash; Goudar, Shivaprasad S.; Okitawutshu, Jean; Tshefu, Antoinette; Bose, Carl L.; Mwenechanya, Musaku; Chomba, Elwyn; Carlo, Waldemar A.; Figueroa, Lester; Garces, Ana; Krebs, Nancy F.; Jessani, Saleem; Saleem, Sarah; Goldenberg, Robert L.; Das, Prabir Kumar; Patel, Archana; Hibberd, Patricia L.; Achieng, Emmah; Nyongesa, Paul; Esamai, Fabian; Bucher, Sherri; Nowak, Kayla J.; Goco, Norman; Nolen, Tracy L.; McClure, Elizabeth M.; Koso-Thomas, Marion; Miodovnik, Menachem; Derman, Richard J.; Medicine, School of MedicineBACKGROUND The daily use of low-dose aspirin may be a safe, widely available, and inexpensive intervention for reducing the risk of preterm birth. Data on the potential side effects of low-dose aspirin use during pregnancy in low- and middle-income countries are needed. OBJECTIVE This study aimed to assess differences in unexpected emergency medical visits and potential maternal side effects from a randomized, double-blind, multicountry, placebo-controlled trial of low-dose aspirin use (81 mg daily, from 6 to 36 weeks’ gestation). STUDY DESIGN This study was a secondary analysis of data from the Aspirin Supplementation for Pregnancy Indicated Risk Reduction In Nulliparas trial, a trial of the Global Network for Women's and Children's Health conducted in India (2 sites), Pakistan, Guatemala, Democratic Republic of the Congo, Kenya, and Zambia. The outcomes for this analysis were unexpected emergency medical visits and the occurrence of the following potential side effects—overall and separately—nausea, vomiting, rash or hives, diarrhea, gastritis, vaginal bleeding, allergic reaction, and any other potential side effects. Analyses were performed overall and by geographic region. RESULTS Between the aspirin (n=5943) and placebo (n=5936) study groups, there was no statistically significant difference in the risk of unexpected emergency medical visits or the risk of any potential side effect (overall). Of the 8 potential side effects assessed, only 1 (rash or hives) presented a different risk by treatment group (4.2% in the aspirin group vs 3.5% in the placebo group; relative risk, 1.20; 95% confidence interval, 1.01–1.43; P=.042). CONCLUSION The daily use of low-dose aspirin seems to be a safe intervention for reducing the risk of preterm birth and well tolerated by nulliparous pregnant women between 6 and 36 weeks’ gestation in low- and middle-income countries.Item The impact of risk factors on aspirin's efficacy for the prevention of preterm birth(Elsevier, 2023) Nuss, Emily E.; Hoffman, Matthew K.; Goudar, Shivaprasad S.; Kavi, Avinash; Metgud, Mrityunjay; Somannavar, Manjunath; Okitawutshu, Jean; Lokangaka, Adrien; Tshefu, Antoinette; Bauserman, Melissa; Mwapule Tembo, Abigail; Chomba, Elwyn; Carlo, Waldemar A.; Figueroa, Lester; Krebs, Nancy F.; Jessani, Saleem; Saleem, Sarah; Goldenberg, Robert L.; Kurhe, Kunal; Das, Prabir; Hibberd, Patricia L.; Achieng, Emmah; Nyongesa, Paul; Esamai, Fabian; Liechty, Edward A.; Bucher, Sherri; Goco, Norman; Hemingway-Foday, Jennifer; Moore, Janet; McClure, Elizabeth M.; Silver, Robert M.; Derman, Richard J.; Aspirin Supplementation for Pregnancy Indicated Risk Reduction In Nulliparas Study Group; Pediatrics, School of MedicineBackground: The Aspirin Supplementation for Pregnancy Indicated Risk Reduction In Nulliparas trial was a landmark study that demonstrated a reduction in preterm birth and hypertensive disorders of pregnancy in nulliparous women who received low-dose aspirin. All women in the study had at least 1 moderate-risk factor for preeclampsia (nulliparity). Unlike current US Preventative Service Task Force guidelines, which recommend low-dose aspirin for ≥2 moderate-risk factors, women in this study were randomized to receive low-dose aspirin regardless of the presence or absence of an additional risk factor. Objective: This study aimed to compare how low-dose aspirin differentially benefits nulliparous women with and without additional preeclampsia risk factors for the prevention of preterm birth and hypertensive disorders of pregnancy. Study design: This was a non-prespecified secondary analysis of the Aspirin Supplementation for Pregnancy Indicated Risk Reduction In Nulliparas trial that randomized nulliparous women with singleton pregnancies from 6 low-middle-income countries to receive low-dose aspirin or placebo. Our primary exposure was having an additional preeclampsia risk factor beyond nulliparity. Our primary outcome was preterm birth before 37 weeks of gestation, and our secondary outcomes included preterm birth before 34 weeks of gestation, preterm birth before 28 weeks of gestation, hypertensive disorders of pregnancy, and perinatal mortality. Results: Among 11,558 nulliparous women who met the inclusion criteria, 66.8% had no additional risk factors. Low-dose aspirin similarly reduced the risk of preterm birth at <37 weeks of gestation in women with and without additional risk factors (relative risk: 0.75 vs 0.85; P=.35). Additionally for our secondary outcomes, low-dose aspirin similarly reduced the risk of preterm birth at <28 weeks of gestation, hypertensive disorders of pregnancy, and perinatal mortality in women with and without additional risk factors. The reduction of preterm birth at <34 weeks of gestation with low-dose aspirin was significantly greater in women without additional risk factors than those with an additional risk factor (relative risk: 0.69 vs 1.04; P=.04). Conclusion: Low-dose aspirin's ability to prevent preterm birth, hypertensive disorders of pregnancy, and perinatal mortality was similar in nulliparous women with and without additional risk factors. Professional societies should consider recommending low-dose aspirin to all nulliparous women.Item Trends over time in the knowledge, attitude and practices of pregnant women related to COVID-19: A cross-sectional survey from seven low- and middle-income countries(Wiley, 2023) Jessani, Saleem; Saleem, Sarah; Fogleman, Elizabeth; Billah, Sk Masum; Haque, Rashidul; Figueroa, Lester; Lokangaka, Adrien; Tshefu, Antoinette; Goudar, Shivaprasad S.; Kavi, Avinash; Esamai, Fabian; Mwenchanya, Musaku; Chomba, Elwyn; Patel, Archana; Das, Prabir; Mazariegos, Manolo; Bauserman, Melissa; Petri, William A., Jr.; Krebs, Nancy F.; Derman, Richard J.; Carlo, Waldemar A.; Bucher, Sherri; Hibberd, Patricia L.; Koso-Thomas, Marion; Bann, Carla M.; McClure, Elizabeth M.; Goldenberg, Robert L.; Pediatrics, School of MedicineObjective: To understand trends in the knowledge, attitudes and practices (KAP) of pregnant women related to COVID-19 in seven low- and middle-income countries. Design: Multi-country population-based prospective observational study. Setting: Study sites in Bangladesh, the Demographic Republic of Congo (DRC), Guatemala, India (two sites), Kenya, Pakistan and Zambia. Population: Pregnant women in the Global Network's Maternal and Neonatal Health Registry (MNHR). Methods: Pregnant women enrolled in the MNHR were interviewed to assess their KAP related to COVID-19 from September 2020 through July 2022 across all study sites. Main outcome measures: Trends of COVID-19 KAP were assessed using the Cochran-Armitage test for trend. Results: A total of 52 297 women participated in this study. There were wide inter-country differences in COVID-19-related knowledge. The level of knowledge of women in the DRC was much lower than that of women in the other sites. The ability to name COVID-19 symptoms increased over time in the African sites, whereas no such change was observed in Bangladesh, Belagavi and Guatemala. All sites observed decreasing trends over time in women avoiding antenatal care visits. Conclusions: The knowledge and attitudes of pregnant women related to COVID-19 varied substantially among the Global Network sites over a period of 2 years; however, there was very little change in knowledge related to COVID-19 over time across these sites. The major change observed was that fewer women reported avoiding medical care because of COVID-19 across all sites over time.
