Anemia and iron deficiency in pregnant Ghanaian women from urban areas
ObjectivesTo determine the prevalence and identify risk factors for iron deficiency and anemia in pregnant Ghanaian women from urban areas.MethodsA crossâ sectional study of 452 healthy pregnant women receiving prenatal care in Accra, Ghana, was conducted. A sociodemographic health questionnaire was performed and hematologic parameters were measured. Logistic regression methods were used to identify risk factors for anemia and iron status.ResultsComplete data were available for 428 women. Anemia (hemoglobin < 11 g/dL) was present in 144 (34%), iron deficiency (ferritin â ¤ 16 μg/L) in 69 (16%), and iron deficiency anemia in 32 (7.5%) women. The adjusted odds ratio (OR) for anemia was 3.4 and 9.8 if iron deficiency and malaria parasitemia were present, respectively; the OR was 0.6 if women were at â ¥ 36 weeks of pregnancy. The adjusted OR for iron deficiency was 2.7 if women were at â ¥ 36 weeks of pregnancy and 0.12 if they had sickle trait.ConclusionAlthough anemia and iron deficiency remain substantial problems in pregnant Ghanaian women from urban areas, their prevalence is less than previously reported.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135515/1/ijgo62.pd
Helping Babies Survive Training Programs: Evaluating a Teaching Cascade in Ethiopia
Background: 2.6 million neonates die annually; the vast majority of deaths occur in low- and middle-income countries (LMICs). The Helping Babies Survive (HBS) programs are commonly used in LMICs to reduce neonatal mortality through education. They are typically disseminated using a train-the-trainer cascade. However, there is little published literature on the extent and cost of dissemination. In 2015, the Ethiopian Ministry of Health and partner organizations implemented a countrywide HBS training cascade for midwives in 169 hospitals.Methods: We quantified the extent of HBS dissemination, and characterized barriers that impeded successful hospital-based training by surveying a representative from each of the 169 participant hospitals. This occurred from September 2017 to April 2018. We also assessed the cost of the training cascade. To assess acquisition of knowledge and skill in the training cascade, multiple-choice question examinations (MCQE) and objective structured clinical evaluations (OSCE) were conducted.Results: Hospital-based training occurred in 132 participant hospitals (78%). 1,146 midwives, 69% of those employed by participant hospitals, received hospital-based training. Barriers included lack of preparation of hospital-based educators and limited logistical support. The cascade cost an average of 2,105 USD per facility or 197 USD per trainee. Knowledge improved and skills were adequate for regional workshop attendees based on MCQE and OSCE performance.Conclusion: The train-the-trainer strategy is an effective and affordable strategy for widespread dissemination of the HBS programs in LMICs. Future studies should assess knowledge and skill acquisition following the variety of pragmatic training approaches that may be employed at the facility-level
An overview of malaria in pregnancy
One hundred twenty-five million pregnant women are at risk for contracting malaria, a preventable cause of maternal and infant morbidity and death. Malaria parasites contribute to adverse pregnancy and birth outcomes due to their preferential accumulation in placental intervillous spaces. Pregnant women are particularly vulnerable to malaria infections, and malaria infections during pregnancy put their fetuses at risk. Malaria in pregnancy is associated with anemia, stillbirth, low birth weight and maternal and fetal death. We review the challenges to diagnosing malaria in pregnancy, as well as strategies to prevent and treat malaria in pregnancy. Finally, we discuss the current gaps in knowledge and potential areas for continued research
Prevention of chronic lung disease
Considerable effort has been devoted to the development of strategies to reduce the incidence of chronic lung disease, including use of medications, nutritional therapies, and respiratory care practices. Unfortunately, most of these strategies have not been successful. To date, the only two treatments developed specifically to prevent CLD whose efficacy is supported by evidence from randomized, controlled trials are the parenteral administration of vitamin A and corticosteroids. Two other therapies, the use of caffeine for the treatment of apnea of prematurity and aggressive phototherapy for the treatment of hyperbilirubinemia were evaluated for the improvement of other outcomes and found to reduce CLD. Cohort studies suggest that the use of CPAP as a strategy for avoiding mechanical ventilation might also be beneficial. Other therapies reduce lung injury in animal models but do not appear to reduce CLD in humans. The benefits of the efficacious therapies have been modest, with an absolute risk reduction in the 7–11% range. Further preventive strategies are needed to reduce the burden of this disease. However, each will need to be tested in randomized, controlled trials, and the expectations of new therapies should be modest reductions of the incidence of the disease
Systemic inflammation associated with mechanical ventilation among extremely preterm infants
Little evidence is available to document that mechanical ventilation is an antecedent of systemic inflammation in preterm humans. We obtained blood on postnatal day 14 from 726 infants born before the 28th week of gestation and measured the concentrations of 25 inflammation-related proteins. We created multivariable models to assess the relationship between duration of ventilation and protein concentrations in the top quartile. Compared to newborns ventilated for fewer than 7 days (N=247), those ventilated for 14 days (N=330) were more likely to have elevated blood concentrations of pro-inflammatory cytokines (IL-1β, TNF-α), chemokines (IL-8, MCP-1), an adhesion molecule (ICAM-1), and a matrix metalloprotease (MMP-9), and less likely to have elevated blood concentrations of two chemokines (RANTES, MIP-1β), a matrix metalloproteinase (MMP-1), and a growth factor (VEGF). Newborns ventilated for 7-13 days (N=149) had systemic inflammation that approximated the pattern of newborns ventilated for 14 days. These relationships were not confounded by chorioamnionitis or antenatal corticosteroid exposure, and were not altered appreciably among infants with and without bacteremia. These findings suggest that two weeks of ventilation are more likely than shorter durations of ventilation to be accompanied by high blood concentrations of pro-inflammatory proteins indicative of systemic inflammation, and by low concentrations of proteins that might protect from inflammation-mediated organ injury
Predictive modeling for perinatal mortality in resource-limited settings
Importance: The overwhelming majority of fetal and neonatal deaths occur in low- and middle-income countries. Fetal and neonatal risk assessment tools may be useful to predict the risk of death.Objective: To develop risk prediction models for intrapartum stillbirth and neonatal death.Design, setting, and participants: This cohort study used data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Global Network for Women\u27s and Children\u27s Health Research population-based vital registry, including clinical sites in South Asia (India and Pakistan), Africa (Democratic Republic of Congo, Zambia, and Kenya), and Latin America (Guatemala). A total of 502 648 pregnancies were prospectively enrolled in the registry.Exposures: Risk factors were added sequentially into the data set in 4 scenarios: (1) prenatal, (2) predelivery, (3) delivery and day 1, and (4) postdelivery through day 2.Main outcomes and measures: Data sets were randomly divided into 10 groups of 3 analysis data sets including training (60%), test (20%), and validation (20%). Conventional and advanced machine learning modeling techniques were applied to assess predictive abilities using area under the curve (AUC) for intrapartum stillbirth and neonatal mortality.Results: All prenatal and predelivery models had predictive accuracy for both intrapartum stillbirth and neonatal mortality with AUC values 0.71 or less. Five of 6 models for neonatal mortality based on delivery/day 1 and postdelivery/day 2 had increased predictive accuracy with AUC values greater than 0.80. Birth weight was the most important predictor for neonatal death in both postdelivery scenarios with independent predictive ability with AUC values of 0.78 and 0.76, respectively. The addition of 4 other top predictors increased AUC to 0.83 and 0.87 for the postdelivery scenarios, respectively.Conclusions and relevance: Models based on prenatal or predelivery data had predictive accuracy for intrapartum stillbirths and neonatal mortality of AUC values 0.71 or less. Models that incorporated delivery data had good predictive accuracy for risk of neonatal mortality. Birth weight was the most important predictor for neonatal mortality
Safety of daily low-dose aspirin use during pregnancy in low-income and middle-income countries
Background: 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\u27 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\u27s and Children\u27s 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\u27 gestation in low- and middle-income countries
A multicountry randomized controlled trial of comprehensive maternal nutrition supplementation initiated before conception: the Women First trial.
Background: Reported benefits of maternal nutrition supplements commenced during pregnancy in low-resource populations have typically been quite limited.
Objectives: This study tested the effects on newborn size, especially length, of commencing nutrition supplements for women in low-resource populations ≥3 mo before conception (Arm 1), compared with the same supplement commenced late in the first trimester of pregnancy (Arm 2) or not at all (control Arm 3).
Methods: Women First was a 3-arm individualized randomized controlled trial (RCT). The intervention was a lipid-based micronutrient supplement; a protein-energy supplement was also provided if maternal body mass index (kg/m2) was(DRC), Guatemala, India, and Pakistan. The primary outcome was length-for-age z score (LAZ), with all anthropometry obtainedDRC, outcomes were determined for all 4 sites from WHO newborn standards (non-gestational-age-adjusted, NGAA) as well as INTERGROWTH-21st fetal standards (3 sites, gestational age-adjusted, GAA).
Results: A total of 7387 nonpregnant women were randomly assigned, yielding 2451 births with NGAA primary outcomes and 1465 with GAA outcomes. Mean LAZ and other outcomes did not differ between Arm 1 and Arm 2 using either NGAA or GAA. Mean LAZ (NGAA) for Arm 1 was greater than for Arm 3 (effect size: +0.19; 95% CI: 0.08, 0.30, P = 0.0008). For GAA outcomes, rates of stunting and small-for-gestational-age were lower in Arm 1 than in Arm 3 (RR: 0.69; 95% CI: 0.49, 0.98, P = 0.0361 and RR: 0.78; 95% CI: 0.70, 0.88, P \u3c 0.001, respectively). Rates of preterm birth did not differ among arms.
Conclusions: In low-resource populations, benefits on fetal growth-related birth outcomes were derived from nutrition supplements commenced before conception or late in the first trimester. This trial was registered at clinicaltrials.gov as NCT01883193
Reduced perinatal mortality following enhanced training of birth attendants in the Democratic Republic of Congo: a time-dependent effect
<p>Abstract</p> <p>Background</p> <p>In many developing countries, the majority of births are attended by traditional birth attendants, who lack formal training in neonatal resuscitation and other essential care required by the newly born infant. In these countries, the major causes of neonatal mortality are birth asphyxia, infection, and low-birth-weight/prematurity. Death from these causes is potentially modifiable using low-cost interventions, including neonatal resuscitation training. The purpose of this study was to evaluate the effect on perinatal mortality of training birth attendants in a rural area of the Democratic Republic of Congo (DRC) using two established programs.</p> <p>Methods</p> <p>This study, a secondary analysis of DRC-specific data collected during a multi-country study, was conducted in two phases. The effect of training using the WHO Essential Newborn Care (ENC) program was evaluated using an active baseline design, followed by a cluster randomized trial of training using an adaptation of a neonatal resuscitation program (NRP). The perinatal mortality rates before ENC, after ENC training, and after randomization to additional NRP training or continued care were compared. In addition, the influence of time following resuscitation training was investigated by examining change in perinatal mortality during sequential three-month increments following ENC training.</p> <p>Results</p> <p>More than two-thirds of deliveries were attended by traditional birth attendants and occurred in homes; these proportions decreased after ENC training. There was no apparent decline in perinatal mortality when the outcome of all deliveries prior to ENC training was compared to those after ENC but before NRP training. However, there was a gradual but significant decline in perinatal mortality during the year following ENC training (RR 0.73; 95% CI: 0.56-0.96), which was independently associated with time following training. The decline was attributable to a decline in early neonatal mortality. NRP training had no demonstrable effect on early neonatal mortality.</p> <p>Conclusion</p> <p>Training DRC birth attendants using the ENC program reduces perinatal mortality. However, a period of utilization and re-enforcement of training may be necessary before a decline in mortality occurs. ENC training has the potential to be a low cost, high impact intervention in developing countries.</p> <p>Trial registration</p> <p>This trial has been registered at <url>http://www.clinicaltrials.gov</url> (identifier <a href="http://www.clinicaltrials.gov/ct2/show/NCT00136708">NCT00136708</a>).</p
Simplified antibiotic regimens for treating neonates and young infants with severe infections in the Democratic Republic of Congo: a comparative efficacy trial
Abstract Background One-quarter of neonatal and infant deaths are due to infection, and the majority of these deaths occur in developing countries. Standard treatment for infection, which includes parenteral treatment only, is often not available in low-resource settings. Infant mortality will not be reduced in developing countries without a reduction in deaths due to infection. We participated in a multi-site trial that demonstrated the effectiveness of three simplified antibiotic regimens compared to standard treatment (The AFRINEST Trial: parent study). For this report, we examined the site-specific data for the Democratic Republic Congo (DRC), the most impoverished of the countries that participated in the study, to determine if outcomes in the DRC were similar to outcomes across all sites. Methods The parent study was an individually randomized, open-label, equivalence trial. Infants with clinical signs of severe infection were randomized to receive one of four regimens: 1) injectable penicillin-gentamicin for 7 days (standard therapy; regimen A), 2) injectable gentamicin and oral amoxicillin for 7 days (regimen B), 3) injectable penicillin-gentamicin for 2 days then oral amoxicillin for 5 days (regimen C), or 4) injectable gentamicin for 2 days and oral amoxicillin for 5 days (regimen D). In the DRC, we enrolled 574 infants, of whom 560 met the per-protocol criteria for analysis of treatment effect. The main outcome was treatment failure within the first week of enrollment. Results Treatment failure occurred in 52 (9.3%) infants: 17 (11.6%) with the referent treatment regimen, 13 (9.6%) with regimen B (risk difference [RD] -2.0%; CI -9.2% to 5.2%), 13 (9.0%) with regimen C (RD -2.6%; CI -9.6% to 4.4%), and 9 (6.7%) with regimen D (RD -5.0%; CI -11.7% to 1.7%). Conclusion As in the parent study, the risk difference between each of the experimental treatments and the reference treatment suggests equivalence. These findings suggest that the conclusion from the parent study, that a simplified antibiotic regimen can be used for the community-based management of possible severe infection in young infants where referral to a hospital for standard care is often not possible, is true in the DRC. We speculate that the widespread use of a simplified, community-based treatment could result in increased coverage with treatment and improved survival in poor areas.
