Abstract
BACKGROUND The appropriate use of obstetric blood transfusion is crucial for patients with placenta previa and prenatal anemia. This retrospective study aims to explore the correlation between prenatal anemia and blood transfusion-related parameters in this population. METHODS We retrieved the medical records of consecutive participants who were diagnosed with placenta previa and underwent cesarean section in our hospital. We compared the baseline demographics and clinical characteristics of patients with and without anemia. The correlation between prenatal anemia and obstetric blood transfusion-related parameters was evaluated using multivariate regression analysis. RESULTS A total of 749 patients were enrolled, with a mean prenatal hemoglobin level of 10.87 ± 1.37 g/dL. Among them, 54.87% (391/749) were diagnosed with anemia. The rate of obstetric blood transfusion was significantly higher in the anemia group (79.54%) compared to the normal group (44.41%). The median allogeneic red blood cell transfusion volume in the anemia group was 4.00 U (IQR 2.00-6.00), while in the normal group, it was 0.00 U (IQR 0.00-4.00). The prenatal hemoglobin levels had a non-linear relationship with intraoperative allogeneic blood transfusion rate, massive blood transfusion rate, red blood cell transfusion units, and fresh plasma transfusion volume in patients with placenta previa, with a threshold of 12 g/dL. CONCLUSIONS Our findings suggest that prenatal anemia is associated with a higher rate of blood transfusion-related parameters in women with placenta previa when the hemoglobin level is < 12 g/dL. These results highlight the importance of promoting prenatal care in placenta previa patients with a high requirement for blood transfusion.

Blood Adv 2023; 7:5954-5967. [PMID: 37307172 PMCID: PMC10562765 DOI: 10.1182/bloodadvances.2023010143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 05/09/2023] [Accepted: 05/30/2023] [Indexed: 06/14/2023] Open
Abstract
Postpartum hemorrhage (PPH) is a leading cause of maternal morbi-mortality. Although obstetric risk factors are well described, the impact of predelivery hematologic and hemostatic biomarkers remains incompletely understood. In this systematic review, we aimed to summarize the available literature on the association between predelivery hemostatic biomarkers and PPH/severe PPH. Searching MEDLINE, EMBASE, and CENTRAL databases from inception to October 2022, we included observational studies on unselected pregnant women without bleeding disorder reporting on PPH and on predelivery hemostatic biomarkers. Two review authors independently performed title, abstract and full-text screening, upon which quantitative syntheses of studies reporting on the same hemostatic biomarker were conducted, calculating the mean difference (MD) between women with PPH/severe PPH and controls. A search on 18 October 2022 yielded 81 articles fitting our inclusion criteria. The heterogeneity between studies was considerable. With regard to PPH, the estimated average MD in the investigated biomarkers (platelets, fibrinogen, hemoglobin, Ddimer, activated partial thromboplastin time, and prothrombin time) were not statistically significant. Women who developed severe PPH had lower predelivery platelets than controls (MD = -26.0 109/L; 95% confidence interval, -35.8 to -16.1), whereas differences in predelivery fibrinogen concentration (MD = -0.31 g/L; 95% confidence interval, -0.75 to 0.13) and levels of factor XIII or hemoglobin were not statistically significant in women with and without severe PPH. Predelivery platelet counts were, on average, lower in women with severe PPH compared with controls, suggesting the potential usefulness of this biomarker for predicting severe PPH. This trial was registered at the International Prospective Register of Systematic Reviews as CRD42022368075.

Maternal low and high hemoglobin concentrations and associations with adverse maternal and infant health outcomes: an updated global systematic review and meta-analysis. BMC Pregnancy Childbirth 2023; 23:264. [PMID: 37076797 PMCID: PMC10114461 DOI: 10.1186/s12884-023-05489-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Accepted: 03/02/2023] [Indexed: 04/21/2023] Open
Abstract
BACKGROUND Growing evidence suggests low and high maternal hemoglobin (Hb) concentrations may have adverse consequences for maternal and child health. There remain questions on specific Hb thresholds to define anemia and high Hb as well as how cutoffs may vary by anemia etiology and timing of assessment. METHODS We conducted an updated systematic review (using PubMed and Cochrane Review) on low (< 110 g/L) and high (≥ 130 g/L) maternal Hb concentrations and associations with a range of maternal and infant health outcomes. We examined associations by timing of Hb assessment (preconception; first, second, and third trimesters, as well as at any time point in pregnancy), varying cutoffs used for defining low and high hemoglobin concentrations and performed stratified analyses by iron-deficiency anemia. We conducted meta-analyses to obtain odds ratios (OR) and 95% confidence intervals. RESULTS The updated systematic review included 148 studies. Low maternal Hb at any time point in pregnancy was associated with: low birthweight, LBW (OR (95% CI) 1.28 (1.22-1.35)), very low birthweight, VLBW (2.15 (1.47-3.13)), preterm birth, PTB (1.35 (1.29-1.42)), small-for-gestational age, SGA (1.11 (1.02-1.19)), stillbirth 1.43 (1.24-1.65)), perinatal mortality (1.75 (1.28-2.39)), neonatal mortality (1.25 (1.16-1.34), postpartum hemorrhage (1.69 (1.45-1.97)), transfusion (3.68 (2.58-5.26)), pre-eclampsia (1.57 (1.23-2.01)), and prenatal depression (1.44 (1.24-1.68)). For maternal mortality, the OR was higher for Hb < 90 (4.83 (2.17-10.74)) than for Hb < 100 (2.87 (1.08-7.67)). High maternal Hb was associated with: VLBW (1.35 (1.16-1.57)), PTB (1.12 (1.00-1.25)), SGA (1.17 (1.09-1.25)), stillbirth (1.32 (1.09-1.60)), maternal mortality (2.01 (1.12-3.61)), gestational diabetes (1.71 (1.19-2.46)), and pre-eclampsia (1.34 (1.16-1.56)). Stronger associations were noted earlier in pregnancy for low Hb and adverse birth outcomes while the role of timing of high Hb was inconsistent. Lower Hb cutoffs were associated with greater odds of poor outcomes; for high Hb, data were too limited to identify patterns. Information on anemia etiology was limited; relationships did not vary by iron-deficiency anemia. CONCLUSION Both low and high maternal Hb concentrations during pregnancy are strong predictors of adverse maternal and infant health outcomes. Additional research is needed to establish healthy reference ranges and design effective interventions to optimize maternal Hb during pregnancy.

Abstract
Background In developing countries, fewer women have access to multidisciplinary congenital heart disease and reproductive programs staffed by experts. We report pregnancy outcomes of a multidisciplinary healthcare strategy utilizing an in-hospital teamwork approach in Vietnam. Methods This retrospective cohort study included pregnant women with unrepaired congenital heart disease managed at a referral cardiovascular center. Results Undiagnosed congenital heart disease before pregnancy, a lack of pre-pregnancy cardiology counseling, and modified World Health Organization class III/IV were common. Under the multispecialty healthcare strategy, although the rate of maternal death was 8.2% in the modified World Health Organization class IV group, no deaths occurred in any other group. Fetal/neonatal complications occurred in 54% of pregnancies, and 49.4% of neonates survived. Poor pregnancy outcomes were associated with admission during the first/seconde trimester for fetus/neonates, third trimester for mother, modified World Health Organization class III/IV, cyanosis, and heart failure. Conclusion The outcomes of pregnant women with unrepaired congenital heart disease were poor but seemed to improve with a multidisciplinary in-hospital healthcare teamwork strategy.

Abstract
Postpartum hemorrhage (PPH) is responsible for 30% to 50% of maternal deaths. There is conflicting evidence if prepartum anemia facilitates PPH. A comprehensive analysis of studies describing their relation is missing. An extensive database search was conducted applying the terms "anemia" OR "hemoglobin" AND "postpartum hemorrhage." We used a random-effects meta-analysis model to estimate an overall odds ratio (OR) for PPH and prepartum anemia, separating studies that were conformant and non-conformant with the World Health Organization (WHO) definitions for anemia. The search yielded 2519 studies, and 46 were appropriate for analysis. The meta-analyses of WHO-conformant (n = 22) and non-conformant (n = 24) studies showed that the risk of PPH was increased when anemia was present. The ORs were 1.45 (CL: 1.23-1.71) for WHO-conformant studies, 2.88 (CL: 1.38-6.02) for studies applying lower thresholds for anemia, and 3.28 (CL: 2.08-5.19) for undefined anemia thresholds. PPH risk appeared to increase with lower anemia thresholds. Prepartum anemia is associated with an increased risk of PPH, an observation that is important regarding improved anemia correction strategies such as iron supplementation.

Ecological analysis of demographic-, nutritional- and housing-related factors associated with anaemia among women of reproductive age group in Nigeria. JOURNAL OF HEALTH, POPULATION, AND NUTRITION 2022; 41:56. [PMID: 36494691 PMCID: PMC9733233 DOI: 10.1186/s41043-022-00334-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 11/04/2022] [Indexed: 06/17/2023]
Abstract
INTRODUCTION Anaemia remains a major public health concern, particularly, in sub-Saharan Africa (SSA), where it is one of the causes of maternal death. The most common cause of maternal anaemia is iron deficiency or malnutrition. This study examined the prevalence of and risk factors for anaemia among women that participated in the Nigerian Demographic Health Survey. METHOD We used data of 14,454 women that participated in the 2018 Nigeria Demographic and Health Survey (NDHS). We extracted information such as demographic, social and housing, dietary characteristics and haemoglobin concentration. The descriptive statistic results, prevalence and 95% confidence interval (CIs) of anaemia with the selected respondents background characteristics were presented. The Poisson regression model with robust variance was used to assess the risk of anaemia among women of reproductive age. All analyses were weighted and adjusted for the complex survey design. Statistical significance was interpreted at p value < 0.05. RESULTS Maternal status, body mass index, education, residence, religion, ethnicity, region and type of cooking fuel were all important determinants of anaemia. The prevalence of anaemia was high among pregnant women (61.8%; 95% CI: 58.5-65.0), adolescents (60.4%; 95% CI: 58.1-62.6), underweight women (62.6%; 95% CI: 59.5-65.5), women who had no formal education (64.1%; 95% CI: 62.2-66.0) and those who belonged to the poorest wealth quintile (65.8%; 95% CI: 63.1-68.4). Similarly, anaemia was high among women residing in rural areas (61.5%; 95% CI: 60.0-63.0), Muslims (59.9%; 95% CI: 58.1-61.6) and women with six or more children (62.1%; 95% CI: 60.0-64.1). The risk of anaemia were 2% less likely among women who took minimum adequate diet compared to those who do not. CONCLUSION To date, this is the largest data on maternal anaemia in Nigeria. The study highlighted the high burden of maternal anaemia in the country and different risk factors (medical and social) that are associated with this medical condition among women of reproductive age. We recommend future longitudinal studies to test hypothesis in order to assess whether there is any causal relationship between identified risk factors and anaemia in this group of women.

Abstract
BACKGROUND Anemia during pregnancy is associated with premature births, low birth weight and increased susceptibility to infection. Nearly a quarter (24.34%) of Ethiopian pregnant women suffer from anemia. Nutritional counseling during antenatal care (ANC) visits may encourage pregnant women to take a more iron-rich diet and prevent anemia. This study examines the association between nutritional counseling during ANC and anemia among Ethiopian women. METHODS This cross-sectional study uses the 2016 Ethiopia Demographic and Health Survey (EDHS) data (n=4, 384). The outcome of interest was anemia, measured objectively by blood hemoglobin level. The main independent variable was the receipt of nutritional counseling during ANC visits. Univariate, bivariate, and multivariable analyses were performed using SAS 9.4. RESULTS Overall, 25.8% of the participants were anemic and 65.7% received nutritional counseling during ANC visits. Compared to women who received nutritional counseling during ANC visits, a significantly higher proportion of women who did not receive nutritional counseling were anemic (23.1% vs. 30.8%; p<0.001). In the multivariable model, compared to women who received nutritional counseling during their ANC visits, the odds of being anemic were higher among women who did not receive nutritional counseling during their ANC visits AOR 1.34 (95% CI) = (1.07-1.67; p=0.010). CONCLUSION In a representative sample of Ethiopian women, exposure to nutritional counseling during ANC visits is associated with a lower likelihood of anemia, independent of potential confounders. Focused ANC counseling that includes nutritional counseling programs during ANC visits can be an effective strategy to prevent and control anemia. This article is protected by copyright.

Abstract
OBJECTIVE To test equivalence of two doses of intravenous iron (ferric carboxymaltose) in pregnancy. DESIGN Parallel, two-arm equivalence randomised controlled trial with an equivalence margin of 5%. SETTING Single centre in Australia. POPULATION 278 pregnant women with iron deficiency. METHODS Participants received either 500 mg (n=152) or 1000mg (n=126) of intravenous ferric carboxymaltose in the second or third trimester. MAIN OUTCOME MEASURES The proportion of participants requiring additional intravenous iron (500mg) to achieve and maintain ferritin >30ug/L (diagnostic threshold for iron deficiency) at 4 weeks post-infusion, and at 6 weeks, and 3-, 6- and 12-months postpartum. Secondary endpoints included repeat infusion rate, iron status, birth, and safety outcomes. RESULTS The two doses were not equivalent within a 5% margin at any timepoint. At 4 weeks post infusion, 26/73 (36%) participants required a repeat infusion in the 500 mg group compared with 5/67 (8%) in the 1000 mg group (difference in proportions, 0.283 95% confidence interval (0.177, 0.389)). Overall, participants in the 500 mg arm received twice the repeat infusion rate (0.81 (SD= 0.824 vs 0.40 (SD= 0.69), rate ratio 2.05, 95% CI (1.45, 2.91)). CONCLUSIONS Administration of 1000 mg ferric carboxymaltose in pregnancy maintains iron stores and reduces the need for repeat infusions. A 500 mg dose requires ongoing monitoring to ensure adequate iron stores are reached and sustained.

Abstract
Background Caesarean section is a common surgery, with almost 23 million procedures performed globally each year. Postpartum haemorrhage, in association with caesarean section surgery, is a leading global cause of maternal morbidity and mortality. Perioperative iron deficiency anaemia is a risk factor for intraoperative bleeding. Therefore, anaemia is an important and modifiable risk factor for bleeding during caesarean section surgery. Recent recommendations advise that all preoperative patients with anaemia (defined as haemoglobin concentration (Hb) < 130 g/L), regardless of sex, be assessed and treated to normalise haemoglobin levels. It is unclear how this recommendation translates to pregnant women where the World Health Organization (WHO) defines anaemia at a much lower threshold (Hb < 110 g/L). We aimed to determine the prevalence, and characterization, of Hb levels < 130 g/L perioperatively in women undergoing caesarean section. Method We conducted a retrospective cohort study of 489 consecutive women who underwent caesarean section over a 12-week period, in a single-centre tertiary referral maternity unit in Australia. We calculated the proportion of women who were anaemic (Hb < 130 g/L) at four time points—first hospital appointment, third trimester, preoperatively and on discharge from hospital. The proportion of women who were iron deficient (ferritin level < 30 μg/L) at their first hospital appointment was determined. Results Haemoglobin was measured in 479 women. Ferritin was measured in 437 of these women. The mean (SD) Hb at the first hospital appointment, third trimester, preoperatively, and postoperatively on discharge was 126.7 (11.4) g/L, 114.6 (10.6) g/L, 124.1 (12.4) g/L, and 108.0 (13.6) g/L respectively. Iron deficiency was present in 148 (33.9%) women at their first hospital appointment; 107 of 248 (43.1%) women with anaemia and 41 of 189 (21.7%) with no anaemia. 29 women were found to have moderate anaemia (Hb 80−109 g/L) with 18 of these 29 (62.1%) women having iron deficiency. Only 68 (45.9%) women with iron deficiency at their first hospital appointment received treatment. The prevalence of anaemia classified as Hb < 130 g/L versus the WHO classification of Hb < 110 g/L from all causes was 57.4% versus 6.1% at first hospital appointment, 94% versus 26.1% in third trimester, and 66.0% versus 12.2% preoperatively. Postoperatively at least 40% of women had Hb < 130 g/L on hospital discharge versus at least 23% of women using WHO definition of Hb < 110 g/L. Of the 112 women with hospital discharge Hb < 110 g/L, 35 (31.3%) women were iron deficient at their first hospital appointment. Conclusion Over one in three women were iron deficient at their first hospital appointment. 62% of women with moderate anaemia (Hb 80–109 g/L) also had iron deficiency. At least four in 10 women were anaemic (Hb < 130 g/L) on hospital discharge. Less than half of the women with anaemia were treated. Our data suggests that 30% of postoperative anaemia may be prevented with intensive treatment of iron deficiency in early pregnancy. Large prospective studies, are needed to determine outcomes after caesarean section in women, stratified by preoperative Hb and ferritin levels. The prevalence of anaemia in our data suggests it is a moderate public health problem.

Abstract
Introduction Anemia is a global health problem that affects all ages, particularly children under five years. If not treated early, childhood anemia results in impaired growth, delayed cognitive development, and organ dysfunction. There is a scarcity of studies on the prevalence of anemia among hospitalized sick neonates, especially in developing countries. Objective This study aimed to determine the magnitude of anemia and associated factors among hospitalized sick newborns at the University of Gondar Comprehensive Specialized Hospital (UOGCSH). Methods An institutional-based cross-sectional study was conducted among admitted newborns from June 1 to September 30, 2020. All newborns whose gestational age (GA) ≥28 weeks and postnatal age ≤28 days, admitted to UOGCSH during the study period were included in the study. Data were collected by pediatric residents and a systematic random sampling technique was used to select the study participants. Statistical analysis was performed using SPSS version 20. Binary logistic regression was used to identify associated factors with neonatal anemia. P-value <0.05 was considered statistically significant. Results During the study period, 272 newborns were enrolled. The mean hemoglobin value was 15.74 ± 4.27 gm/dL. The prevalence of neonatal anemia in the study population was 30.1% (95% CI: 24.6–35.7). Neonatal age >7 days (AOR = 4.41, 95% CI: 1.86–10.5), maternal anemia (AOR = 9.93, 95% CI: 4.36–21.6), antepartum hemorrhage (AOR = 4.05, 95% CI: 1.54–10. 7), being multiple births (AOR = 4.70, 95% CI: 1.73–12.8), subgaleal hemorrhage (AOR = 7.56, 95%: 1.87–30.6), and hyperbilirubinemia (AOR = 3.84, 95% CI: 1.58–9.31) were associated with neonatal anemia. Conclusion and Recommendation The prevalence of anemia among hospitalized newborns was high. The current study recommends that healthcare providers should screen anemia among sick newborns who had risk factors. Prevention of maternal anemia and early treatment of obstetric complications will reduce the burden of anemia in sick neonates.

Abstract
Background Iron-deficiency anemia is a known risk factor for several adverse perinatal outcomes, but data on its impact on specific maternal morbidities is less robust. Further, information on associations between anemia in early pregnancy and subsequent outcomes are understudied. Methods The study population was derived from the Community Level Interventions for Pre-eclampsia (CLIP) trial in Karnataka State, India (NCT01911494). Included were women who were enrolled in either trial arm, delivered by trial end date, and had a baseline measure of hemoglobin (Hb). Anemia was classified by WHO standards into four groups: none (Hb ≥ 11 g/dL), mild (10.0 g/dL ≤ Hb < 11.0 g/dL), moderate (7.0 g/dL ≤ Hb < 10.0 g/dL) and severe (Hb < 7.0 g/dL). Targeted maximum likelihood estimation was used to estimate confounder-adjusted associations between anemia and a composite (and its components) of adverse maternal outcomes, including pregnancy hypertension. E-values were calculated to assess robustness to unmeasured confounding. Results Of 11,370 women included, 10,066 (88.5%) had anemia, that was mild (3690, 32.5%), moderate (6023, 53.0%), or severe (68, 0.6%). Almost all women (> 99%) reported taking iron supplements during pregnancy. Blood transfusions was more often administered to those with anemia that was mild (risk ratio [RR] 2.16, 95% confidence interval [CI] 1.31–3.56), moderate (RR 2.37, 95% CI 1.56–3.59), and severe (RR 5.70, 95% CI 3.00–10.85). No significant association was evident between anemia severity and haemorrhage (antepartum or postpartum) or sepsis, but there was a U-shaped association between anemia severity and pregnancy hypertension and pre-eclampsia specifically, with the lowest risk seen among those with mild or moderate anemia. Conclusion In Karnataka State, India, current management strategies for mild-moderate anemia in early pregnancy are associated with similar rates of adverse maternal or perinatal outcomes, and a lower risk of pregnancy hypertension and preeclampsia, compared with no anemia in early pregnancy. Future research should focus on risk mitigation for women with severe anemia, and the potential effect of iron supplementation for women with normal Hb in early pregnancy.

Abstract
Background Adequate nutritional knowledge, positive attitudes, and good practices of nurses regarding maternal nutrition of women during pregnancy are fundamental for maternal and foetal well-being. Aim This study aimed to determine the knowledge, attitudes, and practices of nurses regarding maternal nutrition in pregnant women. Setting A large hospital and its filter clinics in Lesotho. Methods A descriptive cross-sectional research design was used for this study. The data were collected from 120 nurses working in the reproductive health department of a large hospital and filter clinics, using a self-administered questionnaire. The research was conducted in accordance with the Declaration of Helsinki. Results The nurses showed good knowledge and practices, and positive attitudes regarding maternal nutrition, 88.3%, 99.2% and 62.5%, respectively. There was a significant relationship between attitude and practice, with a correlation coefficient of r = 296, n = 120, and p = 0.001. Conclusion The results of this study show that nurses’ practices were associated with their attitudes regarding maternal nutrition, meaning their attitudes regarding maternal knowledge transcends their related knowledge. Contribution The study contributes to the body of literature about the knowledge, attitudes and practices of nurses related to maternal nutrition. It has the potential to lead to the betterment of nursing care, which in turn results in improved pregnancy outcomes in women.

Abstract
OBJECTIVES This study aims to use the high-quality national monitoring data from the China's National Maternal Near Miss Surveillance System (NMNMSS) to ascertain the incidence, trends and risk factors of obstetric massive blood transfusion (MBT) from 2012 to 2019 in China and determine its clinical outcomes. SETTINGS Observational study of hospitalised pregnancies who had given birth or ended their pregnancy among member hospitals of NMNMSS. PARTICIPANTS 11 667 406 women were included in this study. PRIMARY AND SECONDARY OUTCOME MEASURES We screened for the incidence, trends, risk factors and main reasons for obstetric MBT, and the outcomes after obstetric MBT. MBT was defined as the transfusion of ≥5 units of red blood cells or ≥1000 mL of whole blood. The incidence of MBT was defined as the MBT cases per 10 000 pregnancies. RESULTS Obstetric MBT occurred in 27 626 cases, corresponding to an incidence of 23.68 per 10 000 maternities, which exhibited an increasing trend in China during 2012-2019 (14.03-29.59 per 10 000 maternities, p for trend <0.001). Obstetric MBT was mainly associated with amniotic fluid embolism, uterine atony, abnormal placenta, severe anaemia, ectopic pregnancy, abortion, caesarean section, advanced maternal age and multiparous from biological effect. While from sociological effects, uterine atony, severe anaemia and placenta previa are the top three complications which more likely to undergo obstetric MBT in the Chinese population. Overall, the secular trends of hysterectomy incidence (25.07%-9.92%) and MMR during hospitalisation (21.41‰-7.48‰) among women who underwent MBT showed decreasing trends (p for trend <0.001). CONCLUSION To minimise the incidence of obstetric MBT, more attention should be paid to education on the importance of the antenatal visit, evidence-based transfusion practice and females who are multiparous and have an advanced age, amniotic fluid embolism, uterine atony, severe anaemia and placenta previa.

Abstract
BACKGROUND Maternal anemia is a common pregnancy complication and often leads to a requirement for additional treatments and interventions. Identifying the frequency at which women with antenatally diagnosed anemia experience severe morbidity at the time of admission to the labor and delivery unit will guide future recommendations regarding screening and interventions for anemia during pregnancy. OBJECTIVE The objective of this study was to evaluate the association between antenatally diagnosed anemia and severe maternal morbidity as defined by the Centers for Disease Control and Prevention in a large, contemporary, US cohort. Neonatal outcomes were also examined. STUDY DESIGN This was a secondary analysis of the Consortium on Safe Labor database from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, which collected data on 228,438 deliveries in 19 United States hospitals from 2002 to 2008. This analysis included women with viable, singleton gestations and excluded stillbirths and gestations with severe congenital anomalies. Women with a diagnosis of antenatal anemia were compared with those without. Identification of diagnoses of antenatal anemia was obtained via electronic medical record abstraction and International Classification of Diseases coding according to each hospital protocol within the Consortium on Safe Labor. The primary maternal outcome consisted of a composite of severe maternal morbidity as defined by the Centers for Disease Control and Prevention and included maternal death, eclampsia, thrombosis, transfusion, hysterectomy, and maternal intensive care unit admission. The primary neonatal outcome was a composite that included a 5-minute Apgar score of <7, hypoxic ischemic encephalopathy, respiratory distress syndrome, necrotizing enterocolitis, seizures, intracranial hemorrhage, periventricular or intraventricular hemorrhage, neonatal sepsis, neonatal intensive care unit admission, and neonatal death. Each outcome within the composites was assessed individually along with other additional secondary outcomes, including a composite of severe maternal morbidity not including transfusion morbidity. All statistical analyses were performed with Stata version 14.2 (StataCorp LLC, College Station, TX) using Student's t test, chi-square test, Fisher's exact test, and Wilcoxon rank-sum (Mann-Whitney U) test, as appropriate. A multivariable logistic regression was performed with potential confounding variables entered into the regression equation if they differed between groups at a significance level of P<.05. RESULTS A total of 166,566 women met the inclusion criteria. From the original cohort, 56,734 women could not be included because of an unknown diagnosis of anemia. Of those included, 10,217 (6.1%) were diagnosed with anemia during the pregnancy. Women with anemia were more likely to be younger, non-Hispanic Black, single, multiparous, and have a higher prepregnancy body mass index than those without anemia. The frequency of the primary maternal composite outcome, the neonatal composite outcome, and other secondary outcomes including the severe maternal morbidity composite not including transfusion, maternal death, transfusion during labor and the postpartum period, hysterectomy, postpartum hemorrhage, infectious morbidity, cesarean delivery, and preterm delivery were more common in women with anemia (P<.05). After multivariable logistic regression analysis adjusting for confounders, higher rates of severe maternal morbidity remained persistently associated with anemia (adjusted odds ratio, 2.04; 95% confidence interval, 1.86-2.23) in addition to the association of anemia with the severe maternal morbidity composite not including transfusion, maternal death, thrombosis, transfusion, hysterectomy, intensive care unit admission, postpartum hemorrhage, hypertensive disorders of pregnancy, cesarean delivery, and infectious morbidity. The composite neonatal outcome also remained associated with anemia after adjusting for confounders (adjusted odds ratio, 1.14; 95% confidence interval, 1.06-1.23). CONCLUSION Women with antepartum anemia experienced increased rates of severe maternal morbidity and other serious adverse outcomes. Diagnosis and treatment of anemia during the antepartum period may lead to the identification and treatment of women at higher risk for maternal morbidity and mortality.

Abstract
INTRODUCTION Postpartum hemorrhage (PPH) has remained the leading cause of maternal mortality. While anemia is a leading contributor to maternal morbidity, molecular, cellular and anemia-induced hypoxia, clinical studies of the relationship between prenatal-anemia and PPH have reported conflicting results. Therefore, our objective was to investigate the outcomes of studies on the relationships between prenatal anemia and PPH-related mortality. MATERIALS AND METHODS Electronic databases (MEDLINE, Scopus, ClinicalTrials.gov, PROSPERO, EMBASE, and the Cochrane Central Register of Controlled Trials) were searched for studies published before August 2019. Keywords included "anemia," "hemoglobin," "postpartum hemorrhage," and "postpartum bleeding." Only studies involving the association between anemia and PPH were included in the meta-analysis. Our primary analysis used random effects models to synthesize odds-ratios (ORs) extracted from the studies. Heterogeneity was formally assessed with the Higgins' I2 statistics, and explored using meta-regression and subgroup analysis. RESULTS We found 13 eligible studies investigating the relationship between prenatal anemia and PPH. Our findings suggest that severe prenatal anemia increases PPH risk (OR = 3.54; 95% CI: 1.20, 10.4, p-value = 0.020). There was no statistical association with mild (OR = 0.60; 95% CI: 0.31, 1.17, p-value = 0.130), or moderate anemia (OR = 2.09; 95% CI: 0.40, 11.1, p-value = 0.390) and the risk of PPH. CONCLUSION Severe prenatal anemia is an important predictive factor of adverse outcomes, warranting intensive management during pregnancy.

Abstract
Low-grade inflammation is often present in people living with obesity. Inflammation can impact iron uptake and metabolism through elevation of hepcidin levels. Obesity is a major public health issue globally, with pregnant women often affected by the condition. Maternal obesity is associated with increased pregnancy risks including iron deficiency (ID) and iron-deficiency anaemia (IDA)-conditions already highly prevalent in pregnant women and their newborns. This comprehensive review assesses whether the inflammatory state induced by obesity could contribute to an increased incidence of ID/IDA in pregnant women and their children. We discuss the challenges in accurate measurement of iron status in the presence of inflammation, and available iron repletion strategies and their effectiveness in pregnant women living with obesity. We suggest that pre-pregnancy obesity and overweight/obese pregnancies carry a greater risk of ID/IDA for the mother during pregnancy and postpartum period, as well as for the baby. We propose iron status and weight gain during pregnancy should be monitored more closely in women who are living with overweight or obesity.

[PMID: 33893005 DOI: 10.1016/j.ijoa.2021.102985] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 03/11/2021] [Accepted: 03/17/2021] [Indexed: 11/21/2022]
Abstract
Antepartum anemia impacts over a third of pregnant women globally and is associated with major maternal and perinatal morbidity, including peripartum transfusion, maternal death, maternal infection, preterm birth, and neurodevelopmental disorders among offspring. Postpartum anemia impacts up to 80% of women in low-income and rural populations and up to 50% of women in Europe and the United States, and is associated with postpartum depression, fatigue, impaired cognition, and altered maternal-infant bonding. Iron deficiency is the most common cause of maternal anemia because of insufficient maternal iron stores at the start of pregnancy, increased pregnancy-related iron requirements, and iron losses due to blood loss during parturition. Anemic women should undergo testing for iron deficiency; a serum ferritin cutoff level of 30 μg/L is commonly used to diagnose iron deficiency during pregnancy. The first-line treatment of iron deficiency is oral iron. Intravenous iron is a consideration in the following scenarios: a poor or absent response to oral iron, severe anemia (a hemoglobin concentration <80 g/L), rapid treatment for anemia in the third trimester, women at high risk for major bleeding (such as those with placenta accreta), and women for whom red blood cell transfusion is not an option. Given the high prevalence of antepartum and postpartum anemia, anesthesiologists are advised to partner with other maternal health professionals to develop anemia screening and treatment pathways.

Factors associated with anaemia among women of reproductive age in Ethiopia: Multilevel ordinal logistic regression analysis. MATERNAL & CHILD NUTRITION 2021; 17:e13063. [PMID: 32761751 PMCID: PMC7729796 DOI: 10.1111/mcn.13063] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 06/08/2020] [Accepted: 06/17/2020] [Indexed: 12/27/2022]
Abstract
Anaemia has prevailed as a mild to severe public health problem in Ethiopian women of reproductive age. Many studies carried out on anaemia have been limited to subnational assessments and subgroups of women. The effects of potential factors thought to affect anaemia and severity levels of anaemia have not been well considered. Therefore, this study identifies individual, household and community level factors associated with anaemia among women of reproductive age in Ethiopia applying multilevel ordinal logistic regression models. Proportional odds assumption was tested by likelihood ratio test. About 35.6% of the variation on anaemia was due to between household and community level differences. Pregnancy (adjusted odds ratio [AOR] = 2.30, 95% confidence interval [CI]: 1.82, 2.91), HIV (AOR = 2.40, 95% CI: 1.76, 3.25), giving birth once (AOR = 1.2, 95% CI: 1.05, 1.40), giving birth more than once (AOR = 1.4, 95% CI: 1.19, 1.71), living with five or more family members (AOR = 1.24, 95% CI: 1.05, 1.47), living in poorest households (AOR = 1.34, 95% CI: 1.2, 1.61) and rural area (AOR = 1.57, 95% CI: 1.28, 1.92) were associated with greater odds of more severe anaemia compared with their respective counter parts. Secondary and above education (AOR = 0.83, 95% CI: 0.70, 0.97) and use of pills, implants or injectable (AOR = 0.67, 95% CI: 0.59, 0.77) were associated with lower odds of more severe anaemia. Anaemia prevention and control programmes need to be strengthened for women living with HIV/AIDS and during pregnancy. Household poverty reduction and social protection services need to be strengthened and integrated in anaemia prevention and management activities in women.

Manfredini M. The effects of nutrition on maternal mortality: Evidence from 19th-20th century Italy. SSM Popul Health 2020; 12:100678.

Abstract
The role of nutrition on maternal mortality has been long debated in the historical and scientific literature. Some scholars refute any role of nutrition and diet in the decline of maternal mortality, privileging other causes such as the diffusion of professional midwifery and medical and scientific progress, while others are more open-minded about some possible nutritional effects. The present paper investigates the relationship between maternal mortality and nutrition in Italy between 1887 and 1955 with the purpose to provide new elements and new data to the knowledge of such an association. Using time-series techniques on the official data provided by the National Institute of Statistics, the analysis demonstrates that the trend of maternal mortality was affected by both long- and short-term dynamics of the average daily caloric intake of the Italian population once controlled for the economic situation, here proxied by the annual time series of the GDP per capita. The same analysis clarifies that the impact of nutrition is just one element of a complex picture in which the major role is played by medical advances and scientific progress. The introduction of sulphonamides, in the second half of the thirties of the twentieth century, emerges, in fact, as the turning point in the fight against maternal death.

Abstract
Background Even though anemia was highly targeted in different global strategies, many pregnant and/or lactating women and children were suffering from it and its complications. Besides this, prior trend analysis has not been conducted among pregnant and/or lactating women in Ethiopia. Therefore, this study aimed to assess the trend and determinants of anemia change among pregnant and/or lactating women in Ethiopia. Methods The study utilized two consecutive Ethiopia Demographic and Health Survey (EDHS) datasets. A total of 6,106 and 5,641 pregnant and/or lactating women in 2011 and 2016 survey respectively were included in the analysis. The data were analyzed by using Stata version 14.0. Logit based decomposition analysis was done to identify contributing factors for anemia change and statistical significance was determined by using P-value. Results The trend of anemia was increased from 19% in 2011 to 29% in 2016 EDHS. The analysis revealed that, 8% of the overall change in anemia was because of the change in women’s composition. Changes in the composition of pregnant and/or lactating women according to region, economic status and tobacco and/or cigarette use were the major sources of the change. Greater than 90% of the increase in anemia was due to differences in the coefficient. Mostly, the change in behaviors of the Amhara population, those who had a history of terminated pregnancy and use tobacco and/or cigarette were the sources of the change. Conclusions Anemia among pregnant and/or lactating women was increased against government interventions over the last half-decade in Ethiopia. Programmatic interventions targeting Somali and Dire Dawa regions are still needed to decrease anemia.

Abstract
Anaemia is frequently diagnosed during pregnancy. However, there are few data regarding its incidence, and the association with severe maternal morbidity remains uncertain and potentially biased in high-resource countries. The purpose of this study was to explore the association between gestational anaemia and severe acute maternal morbidity during and after delivery. We performed a cohort-nested case-control analysis from the epidemiology of severe maternal mortality (EPIMOMS) prospective study conducted in six French regions (2012-2013, n = 182,309 deliveries). There were 1669 women with severe acute maternal morbidity during or after delivery, according to a standardised definition obtained by expert consensus. The control group were randomly selected among women without severe morbidity who delivered in the same health centres (n = 3234). We studied the association between gestational anaemia and severe acute maternal morbidity during or after delivery overall, by cause, and by mode of delivery, using multivariable logistic regression and multiple imputation. Gestational anaemia was significantly more frequent in women with severe acute maternal morbidity (25.3%) than in controls (16.3%), p < 0.001, and mostly mild in both groups. After adjustment for confounders, women with gestational anaemia were at increased risk of overall severe acute maternal morbidity during and after delivery (adjusted OR (95%CI) 1.8 (1.5-2.1)). This association was also found for severe postpartum haemorrhage (adjusted OR (95%CI) 1.7 (1.5-2.0)), even after omitting the transfusion criterion (adjusted OR (95%CI) 1.9 (1.6-2.3)), and for severe acute maternal morbidity secondary to causes other than haemorrhage or pregnancy-related hypertensive disorders (adjusted OR (95%CI) 2.7 (1.9-4.0)). These results highlight the importance of optimising the diagnosis and management of anaemia during pregnancy.

Abstract
STUDY QUESTION What is the chance of a treatment-independent live birth following IVF (including ICSI) treatment? SUMMARY ANSWER Over 5 years of follow-up, the treatment-independent live birth rate was 17% in unsuccessfully treated women and 15% in those who had a live birth after IVF. WHAT IS KNOWN ALREADY A limited number of studies have investigated the chance of treatment-independent conception following completion of IVF, but most of them have been based on surveys with poor response rates and limited sample sizes. STUDY DESIGN, SIZE, DURATION This is a population-based, retrospective cohort study of 2133 women who received IVF treatment between 1998 and 2011 at a single regional IVF Unit and were followed for a minimum of 1 year and maximum of 15 years after their last IVF or ICSI treatment cycle. PARTICIPANTS/MATERIALS, SETTING, METHODS This study included all women, residing in the north-east of the UK, who attended the Aberdeen Fertility Clinic and received IVF treatment between 1998 and 2011. Clinical and diagnostic information of all women was linked with treatment and pregnancy outcome data. A total of 2133 women were divided into two groups: (i) those who achieved a live birth following successful IVF or ICSI treatment (n = 1060) and (ii) those in whom treatment was unsuccessful i.e. resulted in either no pregnancy or pregnancy loss (n = 1073). The two groups were followed from the date of the last embryo transfer until the first treatment-independent live birth or 31 December 2012, whichever came first. The primary outcome was the treatment-independent live birth rate at 1, 2.5, 5 and 10 years of follow-up. Cox regression was used to determine factors associated with treatment-independent live birth in each group. MAIN RESULTS AND THE ROLE OF CHANCE Within 5 years of follow-up, the treatment-independent live birth rate was 17% (95% CI, 15-19%) among women whose IVF or ICSI treatment was unsuccessful and 15% (95% CI, 12-17%) among women whose treatment resulted in live birth. In both groups, shorter duration of infertility, younger female age and IVF as compared to ICSI were associated with a higher chance of achieving treatment-independent live birth. Among unsuccessfully treated women, the chance of post-IVF live birth was reduced in those with tubal factor infertility. Three or more previous IVF or ICSI embryo transfers were associated with a lower chance of treatment-independent live birth among successfully treated women. LIMITATIONS, REASONS FOR CAUTION The study was conducted in a single fertility centre, which could compromise the generalizability of the findings. Moreover, data were unavailable on the women's use of contraception or active attempts to get pregnant, both of which could influence treatment-independent live birth rates. WIDER IMPLICATIONS OF THE FINDINGS This study provides a better understanding of the long-term prognosis for treatment-independent live birth after completion of IVF or ICSI treatment. The results will inform women of their chances of a treatment-independent live birth following failed or successful treatment and the factors that are associated with it.

Abstract
BACKGROUND Malaria and HIV are common infections in Africa and cause substantial morbidity and mortality in pregnant women. We aimed to assess the association of malaria with anemia in pregnant women and to explore the joint effects of malaria and HIV infection on anemia in pregnant women. METHODS We used nationally representative, cross-sectional demographic and health surveys (DHS) that were conducted between 2012 and 2017 across 7 countries of sub-Saharan Africa (Burundi, the Democratic Republic of the Congo, Gambia, Ghana, Mali, Senegal and Togo). The outcome variables were anemia (defined as a hemoglobin concentration < 110 g/L), and hemoglobin concentration on a continuous scale, in pregnant women at the time of the interview. We used generalized linear mixed-effects models to account for the nested structure of the data. We adjusted models for individual covariates, with random effects of the primary sampling unit nested within a country. RESULTS A total of 947 pregnant women, ages, 15-49 y, were analyzed. Prevalence of malaria only, HIV only, and malaria- HIV coinfection in pregnant women was 31% (95% CI: 28.5 to 34.5%, n = 293), 1.3% (95% CI: 0.77 to 2.4%, n = 13) and 0.52% (95% CI: 0.02 to 1.3%, n = 5) respectively. Overall prevalence of anemia was 48.3% (95% CI: 45.1 to 51.5%). The anemia prevalence in pregnant women with malaria infection only was 56.0% (95% CI: 50.1 to 61.7%); HIV infection only, 62.5% (95% CI: 25.9 to 89.8%); malaria- HIV coinfection, 60.0 (95% CI: 17.0-92.7%) and without either infection, 44.6% (95% CI: 40.7 to 48.6%). In the fully adjusted models, malaria infection was associated with 27% higher prevalence of anemia (95% CI of prevalence ratio: 1.12 to 1.45; p = 0.004), and 3.4 g/L lower hemoglobin concentration (95% CI: - 5.01 to - 1.79; p = 0.03) compared to uninfected pregnant women. The prevalence of HIV infection and malaria-HIV coinfection was too low to allow meaningful analysis of their association with anemia or hemoglobin concentration. CONCLUSION Malaria was associated with an increased prevalence of anemia during pregnancy.

Abstract
OBJECTIVES To provide an overview of the qualifications of nurses working in antenatal clinics, and to identify current nutrition services and information provided to pregnant women. To explore barriers and enablers to the provision of nutrition services by nurses to pregnant women attending antenatal clinics mapped against the Theoretical Domains Framework. DESIGN AND SETTING Cross-sectional qualitative study, conducted in three municipal hospitals (Temeke, Mwananyamala and Ilala) in Dar es Salaam, Tanzania. PARTICIPANTS Fourteen nurses currently providing health services to pregnant women, with at least two months' work experience within in the selected facility were purposively selected. METHOD In-depth interviews were carried out with the participants by three trained research assistants using guides prepared in Swahili. Transcripts were translated into English and imported to NVivo 12 software. Data was analysed using qualitative content analysis principles. RESULTS Five nutrition services commonly provided to pregnant women at antenatal clinics were nutrition education, iron and folic acid supplementation, weight measurements, dietary assessment and haemoglobin level monitoring. Domains included knowledge, skills, beliefs about capabilities, in addition to memory, attention and decision processes, and the environmental context and resources domains had both barriers and enablers identified by participants. The three remaining domains of the social/professional role and identity, optimism, and beliefs about consequences had only enablers reported. CONCLUSION AND IMPLICATIONS FOR PRACTICE Nurses deliver nutrition care to pregnant women during routine antenatal clinic visits. However, the information delivered to pregnant women varied among nurses, and a number of barriers and enablers to provision of nutrition care to pregnant women were identified. This data can inform future improvement to strategies for implementing nutrition services to pregnant women attending antenatal clinics. In-service training to nurses working with pregnant women and availability of tailored nutrition education materials, such as a food guide in these health facilities could improve nutrition care during this important period.

Abstract
Background Anemia is one of the most common conditions that affect pregnancies, with dietary iron deficiency being its most common cause. Maternal anemia has been associated with increased risks of both maternal and neonatal adverse outcomes. This study aimed to analyze the maternal and neonatal outcomes in women with third-trimester anemia. Methods This was a retrospective report from a Pakistani public hospital. It included data records of the childbirths in the hospital, with at least one record that documented the hemoglobin (Hb) level in women in the first or second trimester and one in the third trimester. The duration of the study was from January 1, 2019 to June 30, 2019. Women with Hb level of <10mg/dL in the third trimester were categorized as anemic, and those with Hb level of >10mg/dL were categorized as non-anemic. Pregnancy outcomes were assessed for both mothers and babies. All data were processed through SPSS version 21.0 for Windows (IBM Corp., Armonk, NY). Results The study evaluated 235 (37.8%) anemic and 387 (62.2%) non-anemic women. Adverse maternal outcomes were compared between the two groups. In anemic women, gestational hypertension (56% vs. 27%; p: <0.0001), preeclampsia (65% vs. 25%; p: <0.0001), antepartum hemorrhage (32% vs. 19%; p: =0.0001), postpartum hemorrhage (79% vs. 28%; p: <0.0001), transfusions (94% vs. 5%; p: <0.0001), prolonged/obstructed labor (49% vs. 20%; p: <0.000), urgent induction of labor (24% vs. 2%; p: <0.0001), and urgent caesarean section (CS) (45% vs. 29%; p: 0.0001) were significantly more common as compared to non-anemic women. Adverse neonatal outcomes such as low birth weight (LBW) (59% vs. 29%; p: <0.0001), small-for-gestational-age (SGA) (73% vs. 23%; p: <0.0001), preterm delivery (39% vs. 15%; p: <0.0001), stillbirth (8% vs. 3%; p: 0.01), and early neonatal death (9% vs. 2%; p: 0.000) were associated more with anemia. There was no report of maternal mortality in either group. Conclusion: Anemia in the third trimester of pregnancy is associated with adverse maternal and neonatal outcomes including neonatal death. Efforts are required to ensure adequate maternal nutritional status in order to prevent poor outcomes.

Abstract
Maternal anemia is a well‐recognized global health problem; however, there remain questions on specific hemoglobin (Hb) thresholds that predict health risk or protection for mother and child. We conducted a systematic review and meta‐analysis to examine the associations of maternal Hb concentrations with a range of maternal and infant health outcomes, accounting for the timing of measurement (preconception, and first, second, and third trimesters), etiology of anemia, and cutoff category. The systematic review included 272 studies and the meta‐analysis included 95 studies. Low maternal Hb (<110 g/L) was associated with poor birth outcomes (low birth weight, preterm birth, small‐for‐gestational‐age (SGA), stillbirth, and perinatal and neonatal mortality) and adverse maternal outcomes (postpartum hemorrhage, preeclampsia, and blood transfusion). High maternal Hb (>130 g/L) was associated with increased odds of SGA, stillbirth, preeclampsia, and gestational diabetes. Relationships varied by the timing of measurement and cutoff category (stronger associations with lower cutoffs); limited data were available on anemia etiology. There were insufficient data for other maternal outcomes and long‐term child health outcomes. Current data are insufficient for determining if revisions to current Hb cutoffs are required. Pooled high‐quality individual‐level data analyses, as well as prospective cohort studies, would be valuable to inform the reevaluation of Hb cutoffs.

Abstract
OBJECTIVE To investigate the association between maternal anemia and low/insufficient birth weight. DESIGN A prospective cohort study of pregnant women who underwent prenatal care at the healthcare units in a municipality of northeast Brazil together with their newborn infants was carried out. The pregnant women were classified as having anemia when the hemoglobin level was below 11 g/dl. Infants who were born full term weighing less than 2500 grams were classified as low birth weight, and those weighing between 2500 and 2999 grams were classified as insufficient weight. The occurrence of maternal anemia and its association with birth weight was verified using crude and adjusted Relative Risk (RR) estimates with their corresponding 95% confidence intervals (95%CIs). RESULTS The final sample was comprised of 622 women. Maternal anemia was considered a risk factor for low/insufficient birth weight, after adjusting the effect measurement for maternal age, family income, urinary infection, parity, alcoholic beverage consumption during pregnancy and gestational body mass index: RRadjusted = 1.38 [95% CI: 1.07 to 1.77]. CONCLUSIONS Maternal anemia was associated with low/insufficient birth weight, representing a risk factor for the gestational outcomes studied.

Abstract
OBJECTIVE To describe the association of maternal anaemia with maternal, fetal, and neonatal outcomes. DESIGN Prospective cohort study. SETTING Rural India and Pakistan. POPULATION Pregnant women residing in the study catchment area. METHODS We performed an analysis of a prospective pregnancy registry in which haemoglobin is commonly obtained as well as maternal, fetal, and neonatal outcomes for 42 days post-delivery. Women 40 years or older who delivered before 20 weeks or had a haemoglobin level of <3.0 g/dl were excluded. Our primary exposure was maternal anaemia, which was categorised in keeping with World Health Organization criteria based on a normal (≥11 g/dl), mild (>10-10.9 g/dl), moderate (7-9.9 g/dl) or severe (<7 g/dl). haemoglobin level. The primary maternal outcome was maternal death, the primary fetal outcome was stillbirth, and the primary neonatal outcome was neonatal mortality <28 days. RESULTS A total of 92 247 deliveries and 93 107 infants were included, of which 87.8% were born to mothers who were anaemic (mild 37.9%, moderate 49.1%, and severe 0.7%). Maternal mortality (number per 100 000) was not associated with anaemia: normal 124, mild 106, moderate 135, and severe 325 (P = 0.64). Fetal and neonatal mortality was associated with severe anaemia: stillbirth rate (n/1000)-normal 27.7, mild 25.8, moderate 30.1, and severe 90.9; P < 0.0001; 28-day neonatal mortality (n/1000)-normal 24.7, mild 22.9, moderate 28.1, and severe 72.6 (P < 0.0001). Severe maternal anaemia was also associated with low birthweight (<2500 and <1500 g), preterm birth, and postpartum haemorrhage. CONCLUSION Severe maternal anaemia is associated with higher risks of poor maternal, fetal, and neonatal outcomes but other degrees of anaemia are not. Interventions directed at preventing severe anaemia in pregnant women should be considered. TWEETABLE ABSTRACT Severe maternal anaemia is associated with adverse fetal and neonatal outcomes in low/middle-income countries.

Abstract
Objective: To systematically analyze the relationship between maternal anemia and low birth weight. Methods: A search of studies was conducted in the main databases (Medline, Embase, Scopus, Web of Science, SciELO, and Lilacs), the gray literature, and the reference lists of selected articles. Cohort and case-control studies that met the eligibility criteria were included in the review. There was no limitation on the language or date of publication. Article selection and data extraction were performed by two independent reviewers. Meta-analyses with random effects, subgroup analyses and meta-regressions were performed. Publication bias was measured using Egger regression and visual funnel plot inspection. Results: A total of 7243 articles were found, of which 71 comprised the systematic review and 68 were included in the meta-analyses. Maternal anemia was associated with low birth weight with an adjusted OR: 1.23 (95% CI: 1.06–1.43) and I2: 58%. The meta-regressions confirmed that the sample size and the methodological quality may partially explain the statistical heterogeneity. Conclusions: Maternal anemia was considered a risk factor for low birth weight.

Abstract
OBJECTIVE To investigate the mechanisms that link maternal haemoglobin concentration with stillbirth. DESIGN A retrospective cohort analysis using anonymised maternity data from two hospitals in England. SETTING The Royal Wolverhampton NHS Trust and Guy's and St Thomas' NHS Foundation Trust. STUDY POPULATION 12 636 women with singleton pregnancies ≥24 weeks of gestation giving birth in the two hospitals during 2013-2015. METHOD A conceptual framework of hypothesised pathways through birth weight-for-gestational age and maternal infection including potential confounders and other risk factors was developed and examined using path-analysis. Path-analysis was performed by fitting a set of regression equations using weighted least squares adjusted for mean and variance. Goodness-of-fit indices were estimated. MAIN OUTCOME MEASURES Coefficient of association (β) for relationship between each parameter, and direct, indirect and total effects via the postulated pathways. RESULTS The path-model showed a significant adjusted indirect negative effect of maternal haemoglobin on stillbirth mediated via birth weight-for-gestational age (standardised estimate (SE)=-0.01; 95% CI=-0.01 to -0.001; P=0.028). The effect through maternal infection was not significant at P<0.05 (SE=0.001; 95% CI=-0.004 to 0.01; P=0.610). There was a residual direct negative effect of maternal haemoglobin on stillbirth (SE=-0.12; 95% CI -0.23 to -0.02; P=0.020) after accounting for the two pathways. Total indirect SE=-0.004; 95% CI -0.01 to 0.003; P=0.267; total direct and indirect SE=-0.13; 95% CI -0.23 to -0.02; P=0.016. The goodness-of-fit indices showed a good fit between the model and the data. CONCLUSION While some of the influence on risk of stillbirth acts through low birth weight-for-gestational age, the majority does not. Several new mechanisms have been suggested for how haemoglobin may be exerting its influence on the risk of stillbirth possibly involving genetic, epigenetic and/or alternative obstetric and nutritional pathologies, but much more research is needed.

Abstract
BACKGROUND Anaemia affects as many as half of all pregnant women in low-income and middle-income countries, but the burden of disease and associated maternal mortality are not robustly quantified. We aimed to assess the association between severe anaemia and maternal death with data from the WHO Multicountry Survey on maternal and newborn health. METHODS We used multilevel and propensity score regression analyses to establish the relation between severe anaemia and maternal death in 359 health facilities in 29 countries across Latin America, Africa, the Western Pacific, eastern Mediterranean, and southeast Asia. Severe anaemia was defined as antenatal or postnatal haemoglobin concentrations of less than 70 g/L in a blood sample obtained before death. Maternal death was defined as death any time after admission until the seventh day post partum or discharge. In regression analyses, we adjusted for post-partum haemorrhage, general anaesthesia, admission to intensive care, sepsis, pre-eclampsia or eclampsia, thrombocytopenia, shock, massive transfusion, severe oliguria, failure to form clots, and severe acidosis as confounding variables. These variables were used to develop the propensity score. FINDINGS 312 281 women admitted in labour or with ectopic pregnancies were included in the adjusted multilevel logistic analysis, and 12 470 were included in the propensity score regression analysis. The adjusted odds ratio for maternal death in women with severe anaemia compared with those without severe anaemia was 2·36 (95% CI 1·60-3·48). In the propensity score analysis, severe anaemia was also associated with maternal death (adjusted odds ratio 1·86 [95% CI 1·39-2·49]). INTERPRETATION Prevention and treatment of anaemia during pregnancy and post partum should remain a global public health and research priority. FUNDING Barts and the London Charity.

The following CBC parameters were analyzed: red blood cell count (RBC), hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red blood cell distribution width (RDW), platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), white blood cell count (WBC), and leukocyte differential count. Reference intervals were established using the 2.5th and 97.5th percentile of the distribution. RESULTS Complete blood count parameters showed dynamic changes during trimesters. RBC, Hb, Hct declined at trimester 1, reaching their lowest point at trimester 2, and began to rise again at trimester 3. WBC, neutrophil count (Neut), monocyte count (MONO), RDW, and PDW went up from trimester 1 to trimester 3. On the contrary, MCHC, lymphocyte count (LYMPH), PLT, and MPV gradually descended during pregnancy. There were statistical significances in all CBC parameters between pregnant women and normal women, regardless of the trimesters (P<.001). The median obtained were (normal vs pregnancy) as follows: RBC 4.50 vs 3.94×1012 /L, Hb 137 vs 120 g/L, WBC 5.71 vs 9.06×109 /L, LYMPH% 32.2 vs 18.0, Neut% 58.7 vs 75.0, and PLT 251 vs 202×109 /L. CONCLUSION The changes of CBC parameters during pregnancy are described, and reference intervals for Beijing pregnant women are demonstrated in this study.

von Dadelszen P, Magee LA. Strategies to reduce the global burden of direct maternal deaths. Obstet Med 2017; 10:5-9. [PMID: 28491124 DOI: 10.1177/1753495x16686287] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Accepted: 11/28/2016] [Indexed: 12/14/2022] Open
Abstract
The leading direct causes of the estimated 196 maternal deaths per 100,000 live births globally are postpartum haemorrhage, the hypertensive disorders of pregnancy, obstructed labour, unsafe abortion and obstetric sepsis. Of the Sustainable Development Goals, one (Sustainable Development Goal 3.1) specifically addresses maternal mortality; by 2030, the goal is to reduce the global maternal mortality ratio to less than 70 per 100,000 live births. Eleven other Sustainable Development Goals provide opportunities to intervene. Unapologetically, this review focusses the reader's attention on health advocacy and its central role in altering the risks that many of the world's women face from direct obstetric causes of mortality. Hard work to alter social determinants of health and health outcomes remains. That work needs to start today to improve the health and social equality of today's girls who will be the women delivering their babies in 2030.
