RESUMO

BACKGROUND: Data regarding effects of small-quantity-lipid-based nutrient supplements (SQ-LNS) on maternal serum zinc concentrations (SZC) in pregnancy and lactation are limited. OBJECTIVES: The objectives of this study were to evaluate the effect of preconception compared with prenatal zinc supplementation (compared with control) on maternal SZC and hypozincemia during pregnancy and early lactation in women in low-resource settings, and assess associations with birth anthropometry. METHODS: From ∼100 women/arm at each of 3 sites (Guatemala, India, and Pakistan) of the Women First Preconception Maternal Nutrition trial, we compared SZC at 12- and 34-wk gestation (n = 651 and 838, respectively) and 3-mo postpartum (n = 742) in women randomly assigned to daily SQ-LNS containing 15 mg zinc from ≥3 mo before conception (preconception, arm 1), from ∼12 wk gestation through delivery (early pregnancy, arm 2) or not at all (control, arm 3). Birth anthropometry was examined for newborns with ultrasound-determined gestational age. Statistical analyses were performed separately for each time point. RESULTS: At 12-wk gestation and 3-mo postpartum, no statistical differences in mean SZC were observed among arms. At 34-wk, mean SZC for arms 1 and 2 were significantly higher than for arm 3 (50.3, 50.8, 47.8 µg/dL, respectively; P = 0.005). Results were not impacted by correction for inflammation or albumin concentrations. Prevalence of hypozincemia at 12-wk (<56 µg/dL) was 23% in Guatemala, 26% in India, and 65% in Pakistan; at 34 wk (<50 µg/dL), 36% in Guatemala, 48% in India, and 74% in Pakistan; and at 3-mo postpartum (<66 µg/dL) 79% in Guatemala, 91% in India, and 92% in Pakistan. Maternal hypozincemia at 34-wk was associated with lower birth length-for-age Z-scores (all sites P = 0.013, Pakistan P = 0.008) and weight-for-age Z-scores (all sites P = 0.017, Pakistan P = 0.022). CONCLUSIONS: Despite daily zinc supplementation for ≥7 mo, high rates of maternal hypozincemia were observed. The association of hypozincemia with impaired fetal growth suggests widespread zinc deficiency in these settings. This trial is registered at clinicaltrials.gov as #NCT01883193.

RESUMO

INTRODUCTION: Pregnant women and their offspring are often at increased direct and indirect risks of adverse outcomes during epidemics and pandemics. A coordinated research response is paramount to ensure that this group is offered at least the same level of disease prevention, diagnosis, and care as the general population. We conducted a landscape analysis and held expert consultations to identify research efforts relevant to pregnant women affected by disease outbreaks, highlight gaps and challenges, and propose solutions to addressing them in a coordinated manner. METHODS: Literature searches were conducted from 1 January 2015 to 22 March 2022 using Web of Science, Google Scholar and PubMed augmented by key informant interviews. Findings were reviewed and Quid analysis was performed to identify clusters and connectors across research networks followed by two expert consultations. These formed the basis for the development of an operational framework for maternal and perinatal research during epidemics. RESULTS: Ninety-four relevant research efforts were identified. Although well suited to generating epidemiological data, the entire infrastructure to support a robust research response remains insufficient, particularly for use of medical products in pregnancy. Limitations in global governance, coordination, funding and data-gathering systems have slowed down research responses. CONCLUSION: Leveraging current research efforts while engaging multinational and regional networks may be the most effective way to scale up maternal and perinatal research preparedness and response. The findings of this landscape analysis and proposed operational framework will pave the way for developing a roadmap to guide coordination efforts, facilitate collaboration and ultimately promote rapid access to countermeasures and clinical care for pregnant women and their offspring in future epidemics.

RESUMO

Objective. To create a prediction model for preterm neonatal mortality. Methods. A secondary analysis was conducted using data from a prospective cohort study, the Project to Understand and Research Preterm Pregnancy Outcome South Asia. The Cox proportional hazard model was used and adjusted hazard ratios (AHR) with 95% confidence intervals (95% CI) were reported. Results. Overall, 3446 preterm neonates were included. The mean age of preterm neonates was 0.65 (1.25) hours and 52% were female. The preterm neonatal mortality rate was 23.3%. The maternal factors predicting preterm neonatal death was any antepartum hemorrhage, AHR 1.99 (1.60-2.47), while neonatal predictors were preterm who received positive pressure ventilation AHR 1.30 (1.08-1.57), temperature <35.5°C AHR 1.18 (1.00-1.39), and congenital malformations AHR 3.31 (2.64-4.16). Conclusion. This study identified key maternal and neonatal predictors of preterm neonatal mortality, emphasizing the need for targeted interventions and collaborative public health efforts to address disparities and regional variations.

RESUMO

BACKGROUND: Postpartum hemorrhage is a leading cause of maternal morbidity and mortality. Tranexamic acid has proven to be useful in treating hemorrhage from acute blood loss. However, its role in preventing blood loss in women at high risk of postpartum hemorrhage undergoing cesarean delivery is not well studied. OBJECTIVE: This study aimed to assess the role of tranexamic acid in reducing blood loss during elective and unscheduled cesarean deliveries in women at high risk of postpartum hemorrhage. STUDY DESIGN: This was a prospective, placebo-controlled, randomized controlled trial from March 2021 to February 2022 at the Karnatak Lingayat Education Society Dr. Prabhakar Kore Hospital and Medical Research Centre, Belagavi, India. Women at a high risk of postpartum hemorrhage undergoing cesarean delivery were recruited and randomized to receive either tranexamic acid or placebo (1:1) at least 10 minutes before skin incision. High-risk factors for postpartum hemorrhage included obesity, hypertension, multiparity, previous cesarean delivery, multiple pregnancy, abnormally implanted placenta, placenta previa, abruption, uterine leiomyomas, polyhydramnios, and fetal macrosomia. The primary outcome was blood loss, calculated by a formula using pre- and postoperative hematocrit levels. In addition, gravimetrically measured blood loss was measured and compared between the 2 groups. RESULTS: A total of 212 women met the inclusion criteria and were randomized (tranexamic acid [n=106] and placebo [n=106]). The mean blood loss estimates were 400.9 mL in the tranexamic acid group and 597.9 mL in the placebo group (P<.001). The mean gravimetrically measured blood loss estimates were 379.2 mL in the tranexamic acid group and 431.1 mL in the placebo group (P<.001). In addition, there was a significant difference in the fall in hemoglobin levels (1.04 vs 1.61 g/dL) and change in hematocrit levels (3.20% vs 4.95%) from the pre- to postoperative period between the 2 groups (P<.001). No difference in the need for additional uterotonics (P=.26) or the need for postoperative parental iron (P=.18) was noted. No woman was transfused in either group. CONCLUSION: High-risk women receiving tranexamic acid had significantly less blood loss than women receiving placebo during cesarean delivery.

RESUMO

BACKGROUND: Newborns with hypoxemia often require life-saving respiratory support. In low-resource settings, it is unknown if respiratory support is delivered more frequently to term infants or preterm infants. We hypothesized that in a registry-based birth cohort in 105 geographic areas in seven low- and middle-income countries, more term newborns received respiratory support than preterm newborns. METHODS: This is a hypothesis-driven observational study based on prospectively collected data from the Maternal and Newborn Health Registry of the NICHD Global Network for Women's and Children's Health Research. Eligible infants enrolled in the registry were live-born between 22 and 44 weeks gestation with a birth weight ≥400 g and born from January 1, 2015, to December 31, 2018. Frequency data were obtained to report the number of term and preterm infants who received treatment with oxygen only, CPAP, or mechanical ventilation. Test for trends over time were conducted using robust Poisson regression. RESULTS: 177,728 (86.3%) infants included in this study were term, and 28,249 (13.7%) were preterm. A larger number of term infants (n = 5,108) received respiratory support compared to preterm infants (n = 3,287). Receipt of each mode of respiratory support was more frequent in term infants. The proportion of preterm infants who received respiratory support (11.6%) was higher than the proportion of term infants receiving respiratory support (2.9%, p < 0.001). The rate of provision of respiratory support varied between sites. CONCLUSIONS: Respiratory support was more frequently used in term infants expected to be at low risk for respiratory disorders compared to preterm infants.

RESUMO

This research describes the proportion of children in four low- and middle-income countries with adequate dietary practices at 6, 12, 18 and 24 months of age and how these practices changed over time using the World Health Organisation and UNICEF's infant young child feeding (IYCF) indicators. The associations between the IYCF indicators and anthropometric z-scores from 6 to 24 months, and between the IYCF indicators and the family care indicators (FCIs) at 24 months are described. This was a longitudinal study of offspring from participants in the Women First Preconception Maternal Nutrition Trial conducted in Sud-Ubangi, Democratic Republic of Congo; Chimaltenango, Guatemala; Belagavi, North Karnataka, India; and Thatta, Sindh Province, Pakistan. The frequency of the minimum dietary diversity (MDD), minimum meal frequency (MMF), and minimum adequate diet (MAD) increased between 6 and 24 months, but even at 24 months MAD remained below 50% at all sites. MDD (ß = 0.12; 95% CI = 0.04-0.22) and MMF (ß = 0.10; 95% CI = 0.03-0.17) were positively associated with length-for-age z-score at 24 months. All IYCF indicators were positively associated with mean total FCI score: MDD (proportion ratio [PR] = 1.04; 95% CI = 1.02-1.07), MMF (PR = 1.02; 95% CI = 1.01-1.04), MAD (PR = 1.05; 95% CI = 1.02-1.08). Although there are multiple barriers to young children having an adequate diet, our results support a positive association between familial interactions and improved IYCF feeding practices.

RESUMO

Introduction: Adolescent (<20 years) and advanced maternal age (>35 years) pregnancies carry adverse risks and warrant a critical review in low- and middle-income countries where the burden of adverse pregnancy outcomes is highest. Objective: To describe the prevalence and adverse pregnancy (maternal, perinatal, and neonatal) outcomes associated with extremes of maternal age across six countries. Patients and methods: We performed a historical cohort analysis on prospectively collected data from a population-based cohort study conducted in the Democratic Republic of Congo, Guatemala, India, Kenya, Pakistan, and Zambia between 2010 and 2020. We included pregnant women and their neonates. We describe the prevalence and adverse pregnancy outcomes associated with pregnancies in these maternal age groups (<20, 20-24, 25-29, 30-35, and >35 years). Relative risks and 95% confidence intervals of each adverse pregnancy outcome comparing each maternal age group to the reference group of 20-24 years were obtained by fitting a Poisson model adjusting for site, maternal age, parity, multiple gestations, maternal education, antenatal care, and delivery location. Analysis by region was also performed. Results: We analyzed 602,884 deliveries; 13% (78,584) were adolescents, and 5% (28,677) were advanced maternal age (AMA). The overall maternal mortality ratio (MMR) was 147 deaths per 100,000 live births and increased with advancing maternal age: 83 in the adolescent and 298 in the AMA group. The AMA groups had the highest MMR in all regions. Adolescent pregnancy was associated with an adjusted relative risk (aRR) of 1.07 (1.02-1.11) for perinatal mortality and 1.13 (1.06-1.19) for neonatal mortality. In contrast, AMA was associated with an aRR of 2.55 (1.81 to 3.59) for maternal mortality, 1.58 (1.49-1.67) for perinatal mortality, and 1.30 (1.20-1.41) for neonatal mortality, compared to pregnancy in women 20-24 years. This pattern was overall similar in all regions, even in the <18 and 18-19 age groups. Conclusion: The maternal mortality ratio in the LMICs assessed is high and increased with advancing maternal age groups. While less prevalent, AMA was associated with a higher risk of adverse maternal mortality and, like adolescence, was associated with adverse perinatal mortality with little regional variation.

RESUMO

BACKGROUND: Anemia is a worldwide problem with iron deficiency being the most common cause. When anemia occurs in pregnancy, it increases the risk of adverse maternal, fetal, and postnatal outcomes. It induces preterm births and low birth weight (LBW) deliveries, long-term neurodevelopmental sequelae, and an increased risk of earlier onset of postnatal iron deficiency. Anemia rates are among the highest in South Asia, and India's National Family Health Survey (NFHS-5) for 2019-2021 indicated that over half of pregnant women, and more than 65% of children, in the country are classified as anemic (Sciences IIfP, National Family Health Survey-5, 2019-21, India Fact Sheet). In 2021, the parent RAPIDIRON Trial (Derman et al., Trials 22:649, 2021) was initiated in two states in India, with the goal of assessing whether a dose of intravenous (IV) iron given to anemic women during early pregnancy results in a greater proportion of participants with normal hemoglobin concentrations in the third trimester and a lower proportion of participants with LBW deliveries compared to oral iron. As a follow-up to the RAPIDIRON Trial, the RAPIDIRON-KIDS Study will follow the offspring of previously randomized mothers to assess, neurobehavioral, hematological, and health outcomes. METHODS: This prospective observational cohort study will follow a subset of participants previously randomized as part of the RAPIDIRON Trial and their newborns. Study visits occur at birth, 6 weeks, 4 months, 12 months, 24 months, and 36 months and include blood sample collection with both maternal and infant participants and specific neurobehavioral assessments conducted with the infants (depending on the study visit). The primary outcomes of interest are (1) infant iron status as indicated by both hemoglobin and ferritin (a) at birth and (b) at 4 months of age and (2) the developmental quotient (DQ) for the cognitive domain of the Bayley Scales of Infant Development Version IV (BSID-IV) at 24 months of age. DISCUSSION: This RAPIDIRON-KIDS Study builds upon its parent RAPIDIRON Trial by following a subset of the previously randomized participants and their offspring through the first 3 years of life to assess neurodevelopmental and neurobehavioral (infants, children), hematological, and health outcomes.

RESUMO

BACKGROUND: Low birthweight (LBW) infants are at increased risk of morbidity and mortality. Exclusive breastfeeding up to six months is recommended to help them thrive through infection prevention, growth improvements, and enhancements in neurodevelopment. However, limited data exist on the feeding experiences of LBW infants, their caregivers and key community influencers. The qualitative component of the Low Birthweight Infant Feeding Exploration (LIFE) study aimed to understand practices, facilitators, and barriers to optimal feeding options in the first six months for LBW infants in low-resource settings. METHODS: This study was conducted in four sites in India, Malawi, and Tanzania from July 2019 to August 2020. We conducted 37 focus group discussions with mothers and family members of LBW infants and community leaders and 142 in-depth interviews with healthcare providers, government officials, and supply chain and donor human milk (DHM) experts. Data were analyzed using a framework approach. RESULTS: All participants believed that mother's own milk was best for LBW infants. Direct breastfeeding was predominant and feeding expressed breast milk and infant formula were rare. DHM was a new concept for most. Adequate maternal nutrition, lactation support, and privacy in the facility aided breastfeeding and expression, but perceived insufficient milk, limited feeding counseling, and infant immaturity were common barriers. Most believed that DHM uptake could be enabled through community awareness by overcoming misconceptions, safety concerns, and perceived family resistance. CONCLUSION: This study fills an evidence gap in LBW infant feeding practices and their facilitators and barriers in resource-limited settings. LBW infants face unique feeding challenges such as poor latching and tiring at the breast. Similarly, their mothers are faced with numerous difficulties, including attainment of adequate milk supply, breast pain and emotional stress. Lactation support and feeding counseling could address obstacles faced by mothers and infants by providing psychosocial, verbal and physical support to empower mothers with skills, knowledge and confidence and facilitate earlier, more and better breast milk feeding. Findings on DHM are critical to the future development of human milk banks and highlight the need to solicit partnership from stakeholders in the community and health system.

RESUMO

OBJECTIVE: To describe our experience of screening with visual inspection with acetic acid (VIA) and colposcopy to identify women with high-grade precancerous cervical lesions who were candidates for cryotherapy. Women were screened to determine eligibility for a clinical trial testing the safety and efficacy of a new, simple and inexpensive cryotherapy device (CryoPop®) targeted for use in low and middle-income countries (LMICs). DESIGN: Prospective cohort study. SETTING: Primary and urban health centres in Belagavi, Hubballi and Vijayapur, India. POPULATION: Women in the age-group 30-49 years, premenopausal, with no prior hysterectomy and no known HIV infection were eligible for screening. METHODS: Visual inspection with acetic acid was performed on eligible women following informed consent. VIA-positive women were referred for colposcopy and biopsy. Biopsies were read by two pathologists independently, with a third pathologist acting as tie-breaker if needed. MAIN OUTCOME MEASURES: The primary outcome measures were the number/proportion of women screening positive by VIA and the number/proportion of those women screening VIA-positive found to have high-grade cervical lesions on biopsy (cervical intraepithelial neoplasia 2/3 [CIN 2/3]). Demographic variables were compared between women who screened VIA-positive and those who screened VIA-negative; a separate comparison of demographic and limited reproductive variables was performed between women who had CIN 2/3 on biopsy and those without CIN 2/3 on biopsy. Chi-square or Fisher's exact tests for categorical data and t-tests or analysis of variance for numeric data were used with all tests two-sided and performed at an alpha 0.05 level of statistical significance. RESULTS: A total of 9130 women were screened with VIA between 4 July 2020 and 31 March 2021. The mean age of all women screened was 37 years (standard deviation = 5.6 years) with 6073 of the women (66.5%) in the 30-39 year range. Only 1% of women reported prior cervical cancer screening. A total of 501 women (5.5%) were VIA-positive; of these, 401 women underwent colposcopy. Of those who had colposcopy, 17 (4.2%) had high-grade lesions on biopsy, an additional 164 (40.9%) had low-grade cervical lesions on biopsy or endocervical curettage and one woman (0.2%) was found to have invasive cancer. VIA-positive women were younger and had higher levels of education and income; however, women who were VIA-positive and found to have CIN 2/3 were older, were more likely to be housewives and had higher household income than those without CIN 2/3. CONCLUSION: Despite the COVID-19 pandemic, over 9100 women were screened with VIA for precancerous lesions. However, only 17 (4.2%) were found to have biopsy-proven high-grade cervical lesions, underscoring the subjective performance of VIA as a screening method. Given that this is significantly lower than rates reported in the literature, it is possible that the prevalence of high-grade lesions in this population was impacted by screening a younger and more rural population. This study demonstrates that screening is feasible in an organised fashion and can be scaled up rapidly. However, while inexpensive and allowing for same-day treatment, VIA may be too subjective and have insufficient accuracy clearly to identify lesions requiring treatment, particularly in low-prevalence and low-risk populations, calling into question its overall cost-effectiveness.

RESUMO

Stillbirth, one of the most common adverse pregnancy outcomes, is especially prevalent in low and middle-income countries (LMICs). Understanding the causes of stillbirth is crucial to developing effective interventions. In this commentary, investigators working across several LMICs discuss the most useful investigations to determine causes of stillbirths in LMICs. Useful data were defined as 1) feasible to obtain accurately and 2) informative to determine or help eliminate a cause of death. Recently, new tools for LMIC settings to determine cause of death in stillbirths, including minimally invasive tissue sampling (MITS) - a method using needle biopsies to obtain internal organ tissue from deceased fetuses for histology and pathogen identification in those tissues have become available. While placental histology has been available for some time, the development of the Amsterdam Criteria in 2016 has provided a useful framework to categorize placental lesions. The authors recommend focusing on the clinical history, the placental evaluation, the external examination of the fetus, and, when available, fetal tissue obtained by MITS, especially of the lung (focused on histology and microbiology) and brain/cerebral spinal fluid (CSF) and fetal blood (focused on microbiological analysis). The authors recognize that this approach may not identify some causes of stillbirth, including some genetic abnormalities and internal organ anomalies, but believe it will identify the most common causes of stillbirth, and most of the preventable causes.

RESUMO

OBJECTIVE: To examine inflammatory lesions in placentas of stillbirths, preterm neonatal deaths and term controls in India and Pakistan. DESIGN: Prospective, observational study. SETTING: Three hospitals in India and a large maternity hospital in Pakistan. POPULATION: The enrolled participants with placentas available for histology evaluation included stillbirths (n = 814), preterm live births who died within 28 days of birth (n = 618) and term live birth controls (n = 201). From this same population, polymerase chain reaction (PCR) analysis for pathogens was performed on 809 stillbirth placentas, 614 neonatal death placentas and the placentas of 201 term controls. Placentas from preterm infants who lived beyond day 28 (n = 1432) were only available from India. METHODS: A prospective observational study of placental inflammatory lesions defined by the Amsterdam criteria and on the same placentas, multiplex PCR evaluation for 75 pathogens using TaqMan Array Cards. MAIN OUTCOME MEASURES: Any placental inflammatory lesions, including chorioamnionitis, funisitis, villitis and intervillitis and their association with various pathogens. RESULTS: In the Indian liveborn preterm infants, placental inflammation of any kind was present in 26.2% of those who died versus 16.6% of those who lived (p = 0.0002). Chorioamnionitis was present in 25.8% of those who died versus 16.3% of those who lived (p = 0.0002) and funisitis was present in 4.1% of those who died versus 1.5% of those who lived, (p = 0.005). Across all three sites, in the placentas of the 201 term controls, 18.9% had any inflammation, 16.9% had chorioamnionitis, 5.5% had funisitis, 0.5% had intervillitis and none had villitis. Overall, for stillbirths, any inflammation was observed in 30.2%, chorioamnionitis in 26.9%, funisitis in 5.7%, intervillitis in 6.0% and villitis in 2.2%. For the neonatal deaths, any inflammation was present in 24.9%, chorioamnionitis in 23.3%, funisitis in 8.1%, intervillitis in 1.9% and villitis in 0.5%. Compared with the placentas of term controls, in neonatal deaths, only chorioamnionitis was significantly increased (23.3% versus 16.9%, p = 0.05). Among stillbirths, the rates of any inflammation, chorioamnionitis, intervillitis and villitis were similar across the birthweight groups. However, funisitis was more common in the placentas of stillborn fetuses weighing 2500 g or more (13.8%) compared with 1.0% for those weighing less than 1000 g and 4.8% for stillborn fetuses weighing 1000-2499 g. In the PCR studies, Ureaplasma spp. were by far the most common pathogens found and generally were more commonly found in association with inflammatory lesions. CONCLUSIONS: Chorioamnionitis was the most common type of placental inflammatory lesion regardless of whether the placentas evaluated were from term controls, stillbirths or neonatal deaths. For stillbirths, inflammation in each inflammation category was more common than in the term controls and significantly more so for any inflammation, chorioamnionitis, intervillitis and villitis. For neonatal deaths, compared with the placentas of term controls, all inflammation categories were more common, but only significantly so for chorioamnionitis. Ureaplasma spp. were the most common organisms found in the placentas and were significantly associated with inflammation.

RESUMO

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. Across the Global Network, in the first year of the study there was little reduction in health care utilisation and no apparent change in pregnancy outcomes. Knowledge related to COVID-19 was highly variable across the sites but was generally poor. Vaccination rates among pregnant women in the Global Network were very low, and were considerably lower than the vaccination rates reported for the countries as a whole. Knowledge regarding vaccines was generally poor and varied widely. Most women did not believe the vaccines were safe or effective, but slightly more than half would accept the vaccine if offered. Based on antibody positivity, the rates of COVID-19 infection increased substantially in each of the sites over the course of the pandemic. Most pregnancy outcomes were not worse in women who were infected with COVID-19 during their pregnancies. We interpret the absence of an increase in adverse outcomes in women infected with COVID-19 to the fact that in the populations studied, most COVID-19 infections were either asymptomatic or were relatively mild.

RESUMO

OBJECTIVE: Group B streptococcus (GBS) has been associated with adverse pregnancy outcomes, but few prospective studies have assessed its prevalence in low- and middle-income country settings. We sought to evaluate the prevalence of GBS by polymerase chain reaction (PCR) in internal organ tissues and placentas of deceased neonates and stillbirths. DESIGN: This was a prospective, observational study. SETTING: The study was conducted in hospitals in India and Pakistan. POPULATION: Pregnant women with stillbirths or preterm births were recruited at delivery, as was a group of women with term, live births, to serve as a control group. METHODS: A rectovaginal culture was collected from the women in Pakistan to assess GBS carriage. Using PCR, we evaluated GBS in various tissues of stillbirths and deceased neonates and their placentas, as well as the placentas of live-born preterm and term control infants. MAIN OUTCOME MEASURES: GBS identified by PCR in various tissues and the placentas; rate of stillbirths and 28-day neonatal deaths. RESULTS: The most obvious finding from this series of analyses from India and Pakistan was that no matter the country, the condition of the subject, the tissue studied or the methodology used, the prevalence of GBS was low, generally ranging between 3% and 6%. Among the risk factors evaluated, only GBS positivity in primigravidae was increased. CONCLUSIONS: GBS diagnosed by PCR was identified in <6% of internal organs of stillbirths and neonatal deaths, and their placentas, and control groups in South Asian sites. This is consistent with other reports from South Asia and is lower than the reported GBS rates from the USA, Europe and Africa.

RESUMO

OBJECTIVE: Peer counsellors are effective in addressing a variety of health challenges, including exclusive breastfeeding (EBF). Providing education and support from a person of similar background and experience has been an important adjunct to the practice of health workers for the past 50 years. DESIGN: It is an exploratory qualitative study. POPULATION OR SAMPLE: Twenty-two peer counsellors. SETTING: In-depth Interview in the community. METHODS: To better understand the experiences of these important health workers, we conducted qualitative interviews with 22 peer counsellors who participated in a research study in Belagavi District, Karnataka, India. Transcripts of the interviews were organised and assigned codes by the research team. MAIN OUTCOME MEASURES: Experience of Peer counsellor's role in the community to improve breastfeeding practices. RESULTS: Peer counsellors had a good understanding of the larger study and of their role. Analysis of the transcripts identified three themes: personal satisfaction; the effect on the larger circle of family and community; and ideas for future programming. The positive experiences and the ability of peers to be trained in counselling women around EBF support their use in breastfeeding support and other areas of health education. CONCLUSIONS: The women from the community who served as peer counsellors were enthusiastic and satisfied about their work, which provided them with opportunities to do meaningful community work outside of their household routines. Use of the peer counsellor model to deliver a specific objective like improvement in EBF rates, immunisation or mental health in integration with healthcare providers can help in achieving desired goals.

RESUMO

OBJECTIVE: To compare placental findings in women with and without pre-eclampsia. DESIGN: The PURPOSe study included women with stillbirths, women with preterm births and women at term as controls. The placenta of each case was evaluated using the Amsterdam criteria. SETTING: Two sites and five tertiary care hospitals of south Asia (Three in India and two in Pakistan). POPULATION: Pregnancies in India and Pakistan with placental histology including women with documented hypertension and documented proteinuria and women with neither hypertension nor proteinuria. METHODS: We compared the placental findings of the two groups using the Amsterdam criteria and further evaluated the placental findings in women with and without pre-eclampsia who had a stillbirth, preterm live birth, or term live birth (control). MAIN OUTCOME MEASURES: The main outcome measures were the frequency of maternal and fetal vascular malperfusion and the frequency of placental inflammation and its components, chorioamnionitis, funisitis, villitis and intervillitis in women with and without pre-eclampsia. RESULTS: A total of 733 women had pre-eclampsia and 2334 women had neither hypertension nor proteinuria. In the placentas of women with pre-eclampsia, 57.3% had maternal vascular malperfusion compared with 37.1% in women without pre-eclampsia (p < 0.0001). There was not a significant difference in the prevalence of fetal vascular hypertension between mothers with (17.1%) and without (14.8%, p = 0.6118) pre-eclampsia. When placentas were classified as 'histologically normal' or not, 61.3% of those from pre-eclamptic pregnancies were classified as abnormal, whereas if there was no pre-eclampsia, only 45.0% were classified as histologically abnormal (p < 0.0001). We also considered rates of placental maternal vascular malperfusion in women with and without pre-eclampsia with stillbirth, preterm neonatal death, and term live birth. In women at term with no pre-eclampsia, 16.7% of the placentas had features of maternal vascular malperfusion. This occurred in 79.9% of women with stillbirths with pre-eclampsia compared with 51.8% of those without pre-eclampsia. Maternal vascular malperfusion was present in 49.7% of preterm live births with pre-eclampsia compared with 33.8% without pre-eclampsia. We also evaluated the inflammatory lesions by whether the mother had or did not have pre-eclampsia. When all inflammatory lesions were considered, women with pre-eclampsia had significantly fewer inflammatory lesions than those women without pre-eclampsia (17.1% versus 23.6% p = 0.001). Each of the specific inflammatory lesions was less common in placentas of women with pre-eclampsia than those with chorioamnionitis (16.1% versus 21.9%, p = 0.004) and funisitis (1.5% versus. 5.1%, p = 0.0004). CONCLUSIONS: Of placental lesions in women with pre-eclampsia, maternal vascular malperfusion was the most common. Inflammatory lesions were less common in women with pre-eclampsia.

RESUMO

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. Among the most important findings were that most stillbirths were caused by fetal asphyxia, often preceded by placental malperfusion, and clinically associated with pre-eclampsia, placental abruption and a small-for-gestational-age fetus. The preterm neonatal deaths were primarily caused by birth asphyxia, followed by various infections. An important finding was that many of the preterm neonatal deaths were caused by a nosocomial infection acquired after neonatal intensive care (NICU) admission; the most common organisms were Acinetobacter baumannii, followed by Klebsiella pneumoniae, Escherichia coli/Shigella and Haemophilus influenzae. Group B streptococcus was less commonly present in the placentas or internal organs of the neonatal deaths.
