Objective: To describe the intrapartum and postpartum use of non-study antibiotics in low- and middle-income countries (LMICs) during the double-blinded NICHD Global Network Azithromycin in Labor (A-PLUS) trial.

Design: The antibiotic use sub-study was a planned prospective, observational sub-study of the A-PLUS trial.

Settings: The study was carried out in hospitals or health centres affiliated with eight sites of the Global Network for Women's and Children's Health Research (Global Network) in seven countries: Bangladesh, Pakistan, India (two sites), Kenya, Zambia, The Democratic Republic of the Congo (DRC) and Guatemala.

Associations between neighborhood characteristics and child well-being before and during the COVID-19 pandemic: A repeated cross-sectional study in the Environmental influences on Child Health Outcomes (ECHO) program.

The corona virus disease (COVID-19) pandemic disrupted daily life worldwide, and its impact on child well-being remains a major concern. Neighborhood characteristics affect child well-being, but how these associations were affected by the pandemic is not well understood. We analyzed data from 1039 children enrolled in the Environmental influences on Child Health Outcomes Program whose well-being was assessed using the Patient-Reported Outcomes Measurement Information System Global Health questionnaire and linked these data to American Community Survey (ACS) data to evaluate the impacts of neighborhood characteristics on child well-being before and during the pandemic.

Neurodevelopment of Children Whose Mothers Were Randomized to Low-Dose Aspirin During Pregnancy.

Objective: Because low-dose aspirin is now commonly prescribed in pregnancy, we sought to assess the association between early antenatal exposure and child neurodevelopment.

Methods: We performed a noninferiority, masked, neurodevelopmental follow-up study of children between age 33 and 39 months whose mothers had been randomized to daily low-dose aspirin (81 mg) or placebo between 6 0/7 and 13 6/7 weeks of gestation through 37 weeks. Neurodevelopment was assessed with the Bayley-III (Bayley Scales of Infant and Toddler Development, 3rd Edition) and the ASQ-3 (Ages and Stages Questionnaire, 3rd Edition).

The PURPOSe cause of death study in stillbirths and neonatal deaths in India and Pakistan: A review.

The PURPOSe study was a prospective, observational study conducted in India and Pakistan to determine the cause of death for stillbirths and preterm neonatal deaths, using clinical data together with minimally invasive tissue sampling (MITS) and the histologic and polymerase chain reaction (PCR) evaluation of fetal/neonatal tissues and the placenta. After evaluating all available data, an independent panel chose a maternal, a placental and a fetal/neonatal cause of death. Here, we summarise the major results.

The impact of risk factors on aspirin's efficacy for the prevention of preterm birth.

Background: 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.

The Global Network COVID-19 studies: a review.

With the paucity of data available regarding COVID-19 in pregnancy in low- and middle-income countries (LMICs), near the start of the pandemic, the Global Network for Women's and Children's Health Research, funded by the National Institute of Child Health and Human Development (NICHD), initiated four separate studies to better understand the impact of the COVID-19 pandemic in eight LMIC sites. These sites included: four in Asia, in Bangladesh, India (two sites) and Pakistan; three in Africa, in the Democratic Republic of the Congo (DRC), Kenya and Zambia; and one in Central America, in Guatemala. The first study evaluated changes in health service utilisation; the second study evaluated knowledge, attitudes and practices of pregnant women in relationship to COVID-19 in pregnancy; the third study evaluated knowledge, attitude and practices related to COVID-19 vaccination in pregnancy; and the fourth study, using antibody status at delivery, evaluated changes in antibody status over time in each of the sites and the relationship of antibody positivity with various pregnancy outcomes.

Design: Prospective, observational study.

Settings: Study hospitals in India and Pakistan.

Positionality, intersectionality, power dynamics in community participatory research to define public safety in Black communities.

Community-based participatory research (CBPR) is necessary for shifting knowledge and empowering community members to establish ownership over research. It was used in this current project to study safety in predominately Black communities. Findings illustrate how the embodiment of power was a present theme and impacted the partnerships among the academics and community, as well as defining "who" could speak on the issues the project was attempting to address.

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.

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.

Azithromycin to Prevent Sepsis or Death in Women Planning a Vaginal Birth.

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.

COVID-19 antibody positivity over time and pregnancy outcomes in seven low-and-middle-income countries: A prospective, observational study of the Global Network for Women's and Children's Health Research.

Objectives: To determine COVID-19 antibody positivity rates over time and relationships to pregnancy outcomes in low- and middle-income countries (LMICs).

Design: With COVID-19 antibody positivity at delivery as the exposure, we performed a prospective, observational cohort study in seven LMICs during the early COVID-19 pandemic.

Setting: The study was conducted among women in the Global Network for Women's and Children's Health's Maternal and Newborn Health Registry (MNHR), a prospective, population-based study in Kenya, Zambia, the Democratic Republic of the Congo (DRC), Bangladesh, Pakistan, India (two sites), and Guatemala.

Accuracy of point-of-care HIV and CD4 field testing by lay healthcare workers in the Botswana Combination Prevention Project.

Accurate HIV and CD4 testing are critical in program implementation, with HIV misdiagnosis having serious consequences at both the client and/or community level. We implemented a comprehensive training and Quality Assurance (QA) program to ensure accuracy of point-of-care HIV and CD4 count testing by lay counsellors during the Botswana Combination Prevention Project (BCPP). We compared the performance of field testing by lay counsellors to results from an accredited laboratory to ascertain accuracy of testing.

-associated peripartum metritis in goats.

is involved in enteric and histotoxic infections in several animal species. In humans, has been linked to gynecological disease, an association not previously investigated in animals. To unveil a potential association of with veterinary reproductive disease, a retrospective search of the database of the California Animal Health and Food Safety Laboratory System (1990-2020) was conducted and identified 9 cases of goats with -associated metritis or endometritis that were confirmed by immunofluorescence antibody test and/or bacterial isolation, and often co-colonized by .

The causes of preterm neonatal deaths in India and Pakistan (PURPOSe): a prospective cohort study.

Background: Preterm birth remains the major cause of neonatal death worldwide. South Asia contributes disproportionately to deaths among preterm births worldwide, yet few population-based studies have assessed the underlying causes of deaths. Novel evaluations, including histological and bacteriological assessments of placental and fetal tissues, facilitate more precise determination of the underlying causes of preterm deaths.

Colonic mucinous adenocarcinoma in a tufted deer: differential diagnosis and literature review.

An 18-y-old female tufted deer () had a short history of chronic diarrhea, progressive weight loss, and hindlimb instability. Given the poor prognosis, the deer was euthanized and submitted for postmortem examination. The most significant gross finding was segmental and multinodular mural thickening of the proximal colon.
