Iron Deficiency Anemia in Pregnancy: Novel Approaches for an Old Problem

Connecting the dots: the role of fatigue in female infertility

Fatigue, an increasingly acknowledged symptom in various chronic diseases, has garnered heightened attention, during the medical era of bio-psycho-social model. Its persistence not only significantly compromises an individual's quality of life but also correlates with chronic organ damage. Surprisingly, the intricate relationship between fatigue and female reproductive health, specifically infertility, remains largely unexplored. Our exploration into the existing body of evidence establishes a compelling link between fatigue with uterine and ovarian diseases, as well as conditions associated with infertility, such as rheumatism. This observation suggests a potentially pivotal role of fatigue in influencing overall female fertility. Furthermore, we propose a hypothetical mechanism elucidating the impact of fatigue on infertility from multiple perspectives, postulating that neuroendocrine, neurotransmitter, inflammatory immune, and mitochondrial dysfunction resulting from fatigue and its co-factors may further contribute to endocrine disorders, menstrual irregularities, and sexual dysfunction, ultimately leading to infertility. In addition to providing this comprehensive theoretical framework, we summarize anti-fatigue strategies and accentuate current knowledge gaps. By doing so, our aim is to offer novel insights, stimulate further research, and advance our understanding of the crucial interplay between fatigue and female reproductive health.

Multiple Infections, Nutrient Deficiencies, and Inflammation as Determinants of Anemia and Iron Status during Pregnancy: The MINDI Cohort

In pregnant women with multiple infections, nutrient deficiencies, and inflammation (MINDI), the study of anemia and iron status is limited. For this cross-sectional study (n = 213 Panamanian indigenous women), we investigated if hemoglobin, anemia (Hb < 110 g/L), ferritin, serum iron, serum transferrin receptor, and hepcidin were associated with (1) maternal nutritional status and supplementation practices, (2) biomarkers of inflammation, and (3) presence/absence of infections. Hierarchical generalized linear and logistic regression models and dominance analyses identified the relative importance of these predictors. Anemia (38%), which was likely underestimated due to low plasma volume (95%), was associated with lower ferritin, vitamin A, and weight-for-height, suggesting anemia of undernutrition. Inflammation was not associated with Hb or anemia; nevertheless, higher CRP was associated with increased odds of low serum iron and higher ferritin and hepcidin, indicating iron restriction due to inflammation. The length of iron supplementation did not enter models for anemia or iron indicators, but a multiple nutrient supplement was associated with higher ferritin and hepcidin. Moreover, iron supplementation was associated with higher odds of vaginal trichomoniasis but lower odds of caries and bacterial vaginosis. The complex pathogenesis of anemia and iron deficiency in MINDI settings may require other interventions beyond iron supplementation.

Current concepts in postpartum anemia management

PURPOSE OF REVIEW

Postpartum anemia (PPA) is common in women after childbirth and affects about 50-80% of all women worldwide. Iron deficiency (ID) is the main cause for anemia and constitutes a potentially preventable condition with great impact on the mother's physical and mental condition after delivery. In most cases, PPA is associated with antenatal ID and peripartum blood losses. Numerous published studies confirmed the positive effect of PPA diagnosis and treatment.

RECENT FINDINGS

Iron deficiency as well as iron deficiency anemia (IDA) are common in the postpartum period and represent significant health problems in women of reproductive age.

SUMMARY

Important movements towards early detection and therapy of postpartum anemia have been observed. However, postpartum anemia management is not implemented on a large scale as many healthcare professionals are not aware of the most recent findings in the field. Diagnosis and therapy of PPA, particularly iron supplementation in ID and IDA, has proven to be highly effective with a tremendous effect on women's wellbeing and outcome.

Exploring progress in iron supplement formulation approaches for treating iron deficiency anemia through bibliometric and thematic analysis

Anemia is a severe health issue that affects around one-third of the global population. Therefore, the present study aims to conduct a bibliometric analysis to investigate the research trends regarding advancements on iron formulations in treating iron deficiency anemia via oral or parenteral route. This study adopts thematic and bibliometric methods on existing research on novel iron formulations. It also provides perspective into the existing understanding on treatment strategies for iron deficiency anemia. This study is conducted on 543 papers on various ferrous and ferric formulations used in the treatment of iron deficiency anemia. The study period is from 1977 to 2022, and the papers are identified from the Scopus database. The bibliometric analysis was carried out using the R tool's Bibliometrix package. The study discusses performance analysis, including annual publications, geographic analysis, relevant affiliations, journal analysis, and citation analysis. In addition, the conceptual structure, including the co-occurrence network, thematic map, thematic evolution, intellectual structure highlighting co-citation analysis, and social structure depicting the collaboration network and collaboration world map, are presented. The results showed increased research on formulation strategies for the treatment of iron deficiency anemia from 2010 onwards. The top 5 contributing countries are the USA, Italy, India, Germany, and the UK, and peer-reviewed journals from the area of nutrition. The most trending areas of study are iron deficiency anemia in pregnancy, chronic kidney diseases, inflammatory bowel diseases, and various intravenous formulations used in its treatment. The authors from Europe collaborate the most with authors from other countries. The study concludes that a safer and more effective iron formulation is needed to reduce the prevalence of anemia. The findings of the study are helpful in advancing research on innovative formulations for treating iron deficiency anemia. The insights from the study are helpful to policymakers in designing specific health policies and investing more in research and development of novel formulations for the treatment of iron deficiency anemia.

Prevalence and Risk Factors for Newborn Anemia in Southwestern Uganda: A Cross-Sectional Study

Introduction

The global prevalence of maternal anemia is about 42%, and in sub-Saharan Africa, the prevalence of newborn anemia ranges from 25% to 30%. Anemia in newborn babies may cause complications such as delayed brain maturation and arrested growth. However, there is limited data on the prevalence of newborn anemia and its risk factors in people living in resource-limited settings.

Objectives

We determined the prevalence and risk factors for newborn anemia and its correlation with maternal anemia in southwestern Uganda.

Methods

This was a cross sectional study of 352 pregnant women presenting to the Mbarara Regional Referral Hospital for delivery. We collected maternal blood in labor and umbilical cord blood from the placental vein. We measured hemoglobin using a point-of-care Hemocue machine. We used summary statistics to characterize the study participants and compared demographic characteristics and outcomes using chi-square, t-test, and Wilcoxon rank sum analyses. We defined newborn anemia as umbilical cord hemoglobin <13 g/dl and measured the relationship between maternal and umbilical cord hemoglobin using linear regression analysis.

Results

The prevalence of newborn anemia was 17%. Maternal parity was significantly higher for anemic than nonanemic newborns (3 versus 2, P=0.01). The mean age in years (SD) was significantly lower for participants with umbilical cord hemoglobin <13 g/dl than those ≥13 g/dl (26 years [5.6] versus 28 [6.3], P=0.01). In multivariable linear regression analysis, a 1-point decrease in maternal hemoglobin was associated with a 0.14-point decrease in umbilical cord hemoglobin (P=0.02). Each one-unit increase in parity was associated with a 0.25-point decrease in umbilical cord hemoglobin (P=0.01). Cesarean delivery was associated with a 0.46-point lower umbilical cord hemoglobin level compared with vaginal delivery (P=0.03).

Conclusions

We found a significant association between maternal and newborn hemoglobin, underscoring the importance of preventing and correcting maternal anemia in pregnancy. Furthermore, maternal anemia should be considered a risk factor for neonatal anemia.

A meta-analysis of ferric carboxymaltose versus other intravenous iron preparations for the management of iron deficiency anemia during pregnancy

Objective

We conducted a meta-analysis of randomized clinical trials evaluating the clinical effects of ferric carboxymaltose therapy compared to other intravenous iron in improving hemoglobin and serum ferritin in pregnant women. We also assessed the safety of ferric carboxymaltose vs. other intravenous iron.

Data source

EMBASE, PubMed, and Web of Science were searched for trials related to ferric carboxymaltose in pregnant women, published between 2005 and 2021. We also reviewed articles from google scholar. The keywords "ferric carboxymaltose," "FCM," "intravenous," "randomized," "pregnancy," "quality of life," and "neonatal outcomes" were used to search the literature. The search was limited to pregnant women.

Selection of studies

Studies related to ferric carboxymaltose in pregnancy were scanned. Observational studies, review articles, and case reports were excluded. Randomized studies in pregnant women involving ferric carboxymaltose and other intravenous iron formulations were shortlisted. Of 256 studies, nine randomized control trials were selected.

Data collection

Two reviewers independently extracted data from nine selected trials.

Data synthesis

The final effect size for increase in hemoglobin after treatment was significant for ferric carboxymaltose vs. iron sucrose/iron polymaltose (standard mean difference 0.89g/dl [95% confidence interval 0.27,1.51]). The final effect size for the increase in ferritin after treatment was more for ferric carboxymaltose vs. iron sucrose/iron polymaltose (standard mean difference 22.53µg/L [-7.26, 52.33]). No serious adverse events were reported with ferric carboxymaltose or other intravenous iron.

Conclusion

Ferric carboxymaltose demonstrated better efficacy than other intravenous iron in increasing hemoglobin and ferritin levels in treating iron deficiency anemia in pregnant women.

Efficacy and Safety of Microsomal Ferric Pyrophosphate Supplement for Iron Deficiency Anemia in Pregnancy

Introduction Anemia during pregnancy is characterized by decreased hemoglobin levels. Iron deficiency poses a significant global health concern, especially in pregnant women, where increased iron demands are crucial for both maternal and fetal well-being. Method In the current study, we investigated the effectiveness and safety of 30 mg SunActiveTM Fe (Taiyo GmbH, Yokkaichi, Japan), emulsified microsomalTM ferric pyrophosphate (EMFP) tablets in treating iron deficiency anemia in 27 second-trimester singleton pregnant women. Results Our study results demonstrated that hemoglobin levels increased significantly within 30 days of treatment and continued to remain higher than baseline throughout the study. Serum ferritin levels exhibited a 6.61-fold increase, maintaining elevated levels consistently. Serum iron also increased significantly by 46.9%. Additionally, symptoms such as nausea, breathlessness, dizziness, irritability, and heartburn were notably reduced, leading to improved quality of life. Subjects reported decreased overall fatigue, indicating an enhanced quality of life. Babies born during the study showed healthy birth weights, with uncomplicated deliveries. High treatment compliance of 99.5% underscored patient commitment to the study. Furthermore, the investigational product demonstrated a favorable safety profile, with only two mild adverse events observed, unrelated to the treatment. Conclusion These findings suggest that EMFP could be a valuable therapeutic option for managing iron deficiency anemia in pregnant women, promoting better maternal and fetal outcomes. Further research with an increased sample size is warranted to delve into the underlying mechanisms behind these positive outcomes, nonetheless, our study provides a promising foundation for addressing this critical health issue.

Acceptability of IV iron treatment for iron deficiency anaemia in pregnancy in Nigeria: a qualitative study with pregnant women, domestic decision-makers, and health care providers

BACKGROUND

Anaemia in pregnancy causes a significant burden of maternal morbidity and mortality in sub-Saharan Africa, with prevalence ranging from 25 to 45% in Nigeria. The main treatment, daily oral iron, is associated with suboptimal adherence and effectiveness. Among pregnant women with iron deficiency, which is a leading cause of anaemia (IDA), intravenous (IV) iron is an alternative treatment in moderate or severe cases. This qualitative study explored the acceptability of IV iron in the states of Kano and Lagos in Nigeria.

METHODS

We purposively sampled various stakeholders, including pregnant women, domestic decision-makers, and healthcare providers (HCPs) during the pre-intervention phase of a hybrid clinical trial (IVON trial) in 10 healthcare facilities across three levels of the health system. Semi-structured topic guides guided 12 focus group discussions (140 participants) and 29 key informant interviews. We used the theoretical framework of acceptability to conduct qualitative content analysis.

RESULTS

We identified three main themes and eight sub-themes that reflected the prospective acceptability of IV iron therapy. Generally, all stakeholders had a positive affective attitude towards IV iron based on its comparative advantages to oral iron. The HCPs noted the effectiveness of IV iron in its ability to evoke an immediate response and capacity to reduce anaemia-related complications. It was perceived as a suitable alternative to blood transfusion for specific individuals based on ethicality. However, to pregnant women and the HCPs, IV iron could present a higher opportunity cost than oral iron for the users and providers as it necessitates additional time to receive and administer it. To all stakeholder groups, leveraging the existing infrastructure to facilitate IV iron treatment will stimulate coherence and self-efficacy while strengthening the existing trust between pregnant women and HCPs can avert misconceptions. Finally, even though high out-of-pocket costs might make IV iron out of reach for poor women, the HCPs felt it can potentially prevent higher treatment fees from complications of IDA.

CONCLUSIONS

IV iron has a potential to become the preferred treatment for iron-deficiency anaemia in pregnancy in Nigeria if proven effective. HCP training, optimisation of information and clinical care delivery during antenatal visits, uninterrupted supply of IV iron, and subsidies to offset higher costs need to be considered to improve its acceptability.

Effect of Prenatal Iron Supplementation Adapted to Hemoglobin Levels in Early Pregnancy on Fetal and Neonatal Growth-ECLIPSES Study

In this randomized clinical trial, we evaluated the effects of prenatal iron supplementation adapted to pregnant women's initial hemoglobin (Hb) levels on fetal growth parameters until birth in women from the Mediterranean coast of northern Spain. All (n = 791) women were iron-supplemented during pregnancy according to Hb levels at the 12th gestational week: stratum 1 (Hb: 110-130 g/L) received 40 or 80 mg iron daily; stratum 2 (Hb > 130 g/L) received 40 or 20 mg iron daily. Fetal biometric and anthropometric measurements were evaluated in the three trimesters and at birth, respectively. In stratum 1, using 80 mg/d instead of 40 mg/d increased the risk of fetal head circumference > 90th percentile (OR = 2.49, p = 0.015) at the second trimester and fetal weight (OR = 2.36, p = 0.011) and femur length (OR = 2.50, p = 0.018) < 10th percentile at the third trimester. For stratum 2, using 40 mg/d instead of 20 mg/d increased the risk of fetal head circumference > 90th percentile (OR = 3.19, p = 0.039) at the third trimester. A higher risk of delivering an LGA baby (OR = 2.35, p = 0.015) for birthweight was also observed in stratum 1 women receiving 80 mg/d. It is crucial to adjust the prenatal iron supplementation to each pregnant woman's needs, i.e., adapted to their initial Hb levels, to achieve optimal fetal development, since excessive iron doses appear to adversely influence fetal growth.

Expert consensus on the role of supplementation in obstetrics and gynecology using modified delphi method

PURPOSE

To reach a consensus among obstetrics and gynecology experts on the effects of micronutrient supplementation on fertility and pregnancy to aid clinicians in decision-making and create a unified approach to managing micronutrient deficiencies in women, by performing a modified Delphi study.

METHODS

A three-round modified Delphi process was conducted among a Delphi panel of 38 Egyptian experts to define recommendations regarding the role of supplementation on fertility and pregnancy in women of reproductive age. A literature review was performed and supporting evidence was graded to help guide the recommendations based on available evidence.

RESULTS

A total of 62 statements were developed for discussion and voting. Out of the 62 statements, 60 statements reached expert consensus. Statements were divided into two domains. The first domain discussed the role of supplementation in fertility: optimizing natural fertility, polycystic ovary syndrome (PCOS), in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI), unexplained infertility, and endometriosis, whereas the second domain was concerned with the role of supplementation in pregnancy during the prenatal, antenatal, and postnatal periods.

CONCLUSION

In this work, a modified Delphi methodology was implemented to reach a consensus on the use of micronutrient supplementation in women of reproductive age. These recommendations can help clinicians in their practice, guide future research, and identify gaps in the market for the pharmaceutical industry. This clinical guidance can be extrapolated to similar communities.

Clinical outcome post treatment of anemia in pregnancy with intravenous versus oral iron therapy: a systematic review and meta-analysis

Oral iron therapy is often the most common way of treating anaemia; however intravenous iron is considered effective due to rapid iron replenishment. We have dearth of evidence on clinical outcomes post treatment of anaemia. We have searched studies published in English in PubMed, Cochrane, Scopus, ProQuest, and Google Scholar. Our study analysed the clinical outcomes amongst neonates and mother and the adverse events post treatment and assessed the mean change in maternal haemoglobin concentration in both the groups. Forest plots for the clinical outcomes are presented. From a total of 370 studies, 34 Randomized and quasi experimental studies comparing clinical outcomes post-treatment of anaemia in pregnancy were included for quantitative evidence synthesis. Pooled results of maternal clinical outcomes using random effect model [OR: 0.79 (95% CI 0.66; 0.95); 10 outcomes; 17 studies] showed statistically significant difference among both the groups [Moderate quality evidence]; however no significant difference [OR: 0.99 (95% CI 0.86; 1.14); 7 outcomes; 8 studies] have been observed for neonatal complications [Low quality evidence]. The study found that pregnant women receiving IV iron were significantly less likely to experience adverse events as compared with those receiving oral iron [OR 0.39;  (95% CI 0.26-0.60)]; 34 studies; 13,909 women; [Low quality evidence]. Findings from meta-regression analysis showed that IV iron is more likely to reduce maternal complications by 21% compared to oral iron. Increase in odds of adverse maternal outcomes was observed due to increase in gestational age and publication year but no effect for the type of drug used. IV iron increases Hb more and at a higher pace than oral iron. Intravenous iron is more likely to avert adverse maternal outcomes and adverse reactions. However, there is no conclusive evidence on its effectiveness on individual maternal outcome or neonatal outcome/s. Protocol registered with PROSPERO CRD42022368346).

Pathophysiology and management of iron deficiency anaemia in pregnancy: a review

According to World Health Organization (WHO), iron deficiency anaemia (IDA) is considered the most prevalent nutritional deficiency worldwide, affecting approximately 30% of the global population. While gastrointestinal bleeding and menstruation in women are the primary causes of IDA, insufficient dietary iron intake and reduced iron absorption contribute to the condition. The aim of IDA treatment is to restore iron stores and normalise haemoglobin levels in affected patients. Iron plays a critical role in various cellular mechanisms, including oxygen delivery, electron transport, and enzymatic activity. During pregnancy, the mother's blood volume increases, and the growing foetus requires a significant increase in iron. Iron deficiency during pregnancy is associated with adverse outcomes such as maternal illness, low birth weight, preterm birth, and intrauterine growth restriction. Iron supplementation is commonly used to treat IDA; however, not all patients benefit from this therapy due to factors such as low compliance and ineffectiveness. In the past, IV iron therapy was underutilised due to its unfavourable and occasionally unsafe side effects. Nevertheless, the development of new type II and III iron complexes has improved compliance, tolerability, efficacy, and safety profiles. This article aims to provide an updated overview of the diagnosis and management of IDA during pregnancy. It will discuss the advantages and limitations of oral versus intravenous iron and the pathophysiology, diagnosis, treatment, and overall management of IDA in pregnancy.

Comprehensive management of Jehovah's Witness in pregnancy

Jehovah's Witness (JW) is a denomination of Christianity which has many-fold higher morbidity and mortality compared to the general population as they refuse blood transfusion. Information is scanty regarding guidelines on the optimal approach to pregnant ladies of JW faith. In this review we have attempted to analyse the ways and techniques available which can be used to reduce the morbidity and mortality of these women. In antenatal care, haematological status can be optimised to reduce modifiable risk factors, namely anaemia by parenteral iron therapy from the second trimester onwards especially in patients who do not respond to oral iron therapy. In severe cases, erythropoietin serves as an effective alternative to blood transfusion. During the intrapartum period, using antifibrinolytics, cell salvage, bloodless surgical techniques, and uterine cooling for patients undergoing caesarean delivery have been proven effective. To conclude, complications of pregnant JW patients may be reduced if they comply with the preventives and targeted monitoring during the various phases of pregnancy. Further studies are warranted as this population exists as a minor group but is growing worldwide.

Women's awareness, knowledge, attitudes, and behaviours towards nutrition and health in Pakistan: Evaluation of kitchen gardens nutrition program

INTRODUCTION

Vulnerability to malnutrition is very high with low-income women and their children in rural Balochistan with contributing factors including lack of awareness about proper nutrition, low literacy, scarcity of vegetables and fruit, and low purchasing power of households. The Food and Agriculture Organization's kitchen garden program provides resources to improve nutrition and health knowledge and promote healthy eating practices. The objective of this study was to assess nutrition and health awareness, knowledge, attitudes, behavioural intentions/behaviours (AKAB) of women who attended the kitchen garden program and trainings.

MATERIALS AND METHODS

A community based cross-sectional survey (N = 209) using a two-stage cluster sampling method was used to select households with survey participants being mothers with children under five years of age. A pretested questionnaire was administered via face-to-face surveys by trained enumerators in two districts of Balochistan province of Pakistan. Nutrition and health AKAB were constructed indices. Chi-square tests compared statistical differences in AKAB by women attending against a control group who did not-attend kitchen garden interventions. Binary logistic regression analyses were performed to assess kitchen garden program outcomes against key AKAB indicators, while adjusting for covariates.

RESULTS

Significant differences (p<0.001) were identified between intervention and control groups with women attending kitchen garden being more aware of the components of kitchen garden (65.8% vs 36.8%), and more knowledgeable about causes of illnesses caused by poor nutrition including, iron deficiency anemia, pregnancy, and unborn child health complications, compared to women not attending kitchen gardens program. Logistic regression analysis identified women attending kitchen gardens also had higher odds of being more knowledgeable (OR = 1.59, 95%CI 1.27-1.99, p<0.001), having improved attitudes (OR = 4.86, 95%CI 2.77-8.53, p <0.001), and behavioural intentions/behaviours (OR = 1.98, 95%CI 1.26-3.12, p = 0.003) towards improved nutrition and health.

CONCLUSIONS

Substantial opportunities exist for achieving improved nutrition and health outcomes with vulnerable groups in Balochistan, through greater participation in kitchen gardens behavioural change programs and interventions. As part of scaling-up efforts, academically rigorous project evaluations should be institutionalized for continuous improvement of nutrition programs to address micronutrient deficiencies in rural communities.

Direct Dispensation of Prenatal Supplements With Iron and Anemia Among Pregnant People

Importance

Postpartum transfusion is the most common indicator of severe maternal morbidity in the US. Higher rates of anemia are associated with a higher blood transfusion rate.

Objective

To determine if providing, rather than recommending, supplements with iron at prenatal visits in a medically underserved community is associated with improved hematologic indices and reduced blood transfusion.

Design, Setting, and Participants

In this quality improvement study, patients who delivered between May 13 and December 13, 2020, and thus were provided a prenatal supplement with iron throughout pregnancy were compared with those who delivered between January 1 and August 1, 2019, before supplements were dispensed. The study was conducted at Parkland Health, a safety net hospital in Dallas, Texas, with a 95% Medicaid-funded or self-pay population and included all patients who delivered at our institution during the study period with available hematologic data.

Exposures

In the earlier cohort, all patients were recommended to obtain and take iron supplements. In the later cohort, prenatal supplements with iron were dispensed via clinic pharmacy to all patients during prenatal visits.

Main Outcomes and Measures

Maternal hematocrit levels (28-32 weeks, delivery admission, and discharge), rates of anemia (hematocrit <30%), and postpartum transfusion for acute blood loss anemia were compared using χ2 and analysis of variance methods with P < .05 considered significant. The analysis took place in July of 2022.

Results

Overall, 13 910 patients (98%) met inclusion criteria (mean age [SD], 27.9 [6.5] and 27.6 [6.5] years, mean [SD] body mass index at first visit, 29.2 [6.6] and 29.3 [6.6]). Mosty of the patients in both cohorts were of Hispanic ethnicity (76%). Providing iron-containing prenatal supplements was associated with higher average hematocrit levels at all time points including a mean difference of 1.27% (95% CI, 1.13%-1.42%) on admission for delivery, when compared with those who were not directly dispensed iron. Among patients prior to providing supplements, 18% had anemia on admission compared with 11% with iron-containing supplements dispensed (risk ratio [RR], 0.61; 95% CI, 0.56-0.66). Postpartum transfusion for acute blood loss anemia was reduced by one-third in patients after program implementation from 10 per 1000 to 6.6 per 1000 (RR, 0.62; 95% CI, 0.43-0.91).

Conclusions and Relevance

In this quality improvement study, providing supplements with iron to patients at prenatal visits was associated with improved hematocrit levels, rates of anemia, and reduced transfusions unrelated to obstetric catastrophes among a predominantly Medicaid population.

Maternal Iron Status Is Dynamic Throughout Pregnancy and Might Predict Birth Outcomes in a Sex Dependent Manner: Results from the Alberta Pregnancy Outcomes and Nutrition (APrON) Cohort Study

BACKGROUND

Developmental responses to nutrient deprivation may differ by fetal sex. Despite this, relationships between maternal prenatal iron biomarkers and birth outcomes when stratifying by offspring sex are poorly described, especially in healthy cohorts.

OBJECTIVES

This study aimed to determine associations between maternal iron biomarkers and birth weights (BWs) and birth head circumferences (BHCs) among female and male newborns to assess whether the potential predictive ability of iron biomarkers on birth outcomes differs by offspring sex.

METHODS

The Alberta Pregnancy Outcomes and Nutrition (APrON) cohort study recruited 2189 pregnant individuals from Calgary and Edmonton, Canada. Maternal blood was drawn at each trimester and 3 mo postpartum. Maternal serum ferritin (SF) concentrations were measured using chemiluminescent immunoassays and erythropoietin (EPO), hepcidin, and soluble transferrin receptor (sTfR) using enzyme-linked immunosorbent assays. Ratios of sTfR:SF and hepcidin:EPO were calculated and birth outcomes accessed through delivery records. Directed acyclic graphs informed multivariate regression models.

RESULTS

The risk of maternal iron deficiency increased throughout pregnancy because ∼61% showed depleted iron stores (SF < 15 μg/L) by the third trimester. Maternal hepcidin, SF, sTfR, and sTfR:SF concentrations changed across time (P < 0.01), and participants carrying female fetuses consistently (across 6 biomarkers) showed a lower iron status during the third trimester compared with those with male fetuses (P < 0.05). Higher maternal SF and hepcidin:EPO during the third trimester was associated with lower BWs in males (P = 0.006 for SF; P = 0.03 for hepcidin:EPO) and females (P = 0.02 for SF; P = 0.02 for hepcidin:EPO). There were additional inverse associations between BWs and third trimester maternal hepcidin (P = 0.03) and hemoglobin (P = 0.004) and between BHCs and maternal SF (second trimester; P < 0.05) and Hb (third trimester P = 0.02) but only in males.

CONCLUSIONS

Relationships between maternal iron biomarkers and BWs and BHCs may depend on the timing of pregnancy and offpsring sex. There was a high risk of third trimester iron storage depletion among generally healthy pregnant individuals.

Maternal risk factors for low birthweight and macrosomia: a cross-sectional study in Northern Region, Ghana

BACKGROUND

Abnormal birthweights are critical public health challenges accountable for most non-communicable diseases and perinatal mortalities. Regardless of the myriad of mixed evidence on maternal factors responsible for abnormal birthweight globally, most of these findings are attained from urban and rural settings. This study serves as one of the key pieces of evidence in view of the increasing prevalence of abnormal birthweight particularly in some parts of semi-rural Ghana. The study, therefore, aims to estimate the prevalence of abnormal birthweight and identify some possible maternal risk factors for abnormal birthweight in Northern Ghana.

METHODS

A retrospective cross-sectional study was conducted in Savelugu municipality from February-March 2022. A total of 356 mothers aged 16-46 years, having a neonate and attending postnatal care service, were recruited as study participants. Data were collected from maternal and child health record books and through structured interviews. To identify the maternal risk factors for abnormal birthweight, chi-square/Fischer's exact test and multinomial logistic regression were employed as bivariate and multivariate analyses, respectively, at 95% confidence level.

RESULTS

Prevalence rates of low birthweight and macrosomia were 22.2% and 8.7%, respectively. Maternal anaemia in first trimester (AOR 3.226; 95% CI 1.372-7.784) and third trimester (AOR 23.94; 95% CI 7.442-70.01) of gestation was strong predictors for low birthweight. Mothers belonging to minority ethnic groups (AOR 0.104; 95% CI 0.011-0.995); mothers who had ≥ 8 antenatal care visits (AOR 0.249; 95% CI 0.103-0.602); and mothers having neonates whose birth length > 47.5 cm (AOR 0.271; 95% CI 0.113-0.651) had reduced odds for low birthweight. Alternatively, mothers with gestational weeks ≥ 42 (AOR 23.21; 95% CI 4.603-56.19) and mothers from the richest households (highest socioeconomic homes) (AOR 14.25; 95% CI 1.638-23.91) were more likely to birth to macrosomic infants.

CONCLUSION

The prevalence rates of low birthweight and macrosomia were relatively high. Anaemia in the first and third trimesters was strong determinants of low birthweight. Being minority ethnic group, frequency of antenatal visits, and childbirth length reduced the risk of low-weight births. Advanced gestational age and socioeconomic status of mothers were also predictors of macrosomia. Hence, nutrition counselling, community health education, and promotion of lifestyle improvement coupled with strengthening of health service delivery are recommended interventions.

Perinatal iron restriction is associated with changes in neonatal cardiac function and structure in a sex-dependent manner

Iron deficiency (ID) is common during gestation and in early infancy and can alter developmental trajectories with lasting consequences on cardiovascular health. While the effects of ID and anemia on the mature heart are well documented, comparatively little is known about their effects and mechanisms on offspring cardiac development and function in the neonatal period. Female Sprague-Dawley rats were fed an iron-restricted or iron-replete diet before and during pregnancy. Cardiac function was assessed in a cohort of offspring on postnatal days (PD) 4, 14, and 28 by echocardiography; a separate cohort was euthanized for tissue collection and hearts underwent quantitative shotgun proteomic analysis. ID reduced body weight and increased relative heart weights at all time points assessed, despite recovering from anemia by PD28. Echocardiographic studies revealed unique functional impairments in ID male and female offspring, characterized by greater systolic dysfunction in the former and greater diastolic dysfunction in the latter. Proteomic analysis revealed down-regulation of structural components by ID, as well as enriched cellular responses to stress; in general, these effects were more pronounced in males. ID causes functional changes in the neonatal heart, which may reflect an inadequate or maladaptive compensation to anemia. This identifies systolic and diastolic dysfunction as comorbidities to perinatal ID anemia which may have important implications for both the short- and long-term cardiac health of newborn babies. Furthermore, therapies which improve cardiac output may mitigate the effects of ID on organ development.

Prevalence and determinants of maternal near miss in Ethiopia: a systematic review and meta-analysis, 2015-2023

BACKGROUND

One of the most challenging problems in developing countries including Ethiopia is improving maternal health. About 303,000 mothers die globally, and one in every 180 is at risk from maternal causes. Developing regions account for 99% of maternal deaths. Maternal near miss (MNM) resulted in long-term consequences. A systematic review and meta-analysis was performed to assess the prevalence and predictors of maternal near miss in Ethiopia from January 2015 to March 2023.

METHODS

A systematic review and meta-analysis cover both published and unpublished studies from different databases (PubMed, CINHAL, Scopus, Science Direct, and the Cochrane Library) to search for published studies whilst searches for unpublished studies were conducted using Google Scholar and Google searches. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Duplicated studies were removed using Endnote X8. The paper quality was also assessed based on the JBI checklist. Finally, 21 studies were included in the study. Data synthesis and statistical analysis were conducted using STATA Version 17 software. Forest plots were used to present the pooled prevalence using the random effect model. Heterogeneity and publication bias was evaluated using Cochran's Q test, (Q) and I squared test (I²). Subgroup analysis based on study region and year of publication was performed.

RESULT

From a total of 705 obtained studies, twenty-one studies involving 701,997 pregnant or postpartum mothers were included in the final analysis. The national pooled prevalence of MNM in Ethiopia was 140/1000 [95% CI: 80, 190]. Lack of formal education [AOR = 2.10, 95% CI: 1.09, 3.10], Lack of antenatal care [AOR = 2.18, 95% CI: 1.33, 3.03], history of cesarean section [AOR = 4.07, 95% CI: 2.91, 5.24], anemia [AOR = 4.86, 95% CI: 3.24, 6.47], and having chronic medical disorder [AOR = 2.41, 95% CI: 1.53, 3.29] were among the predictors of maternal near misses from the pooled estimate.

CONCLUSION

The national prevalence of maternal near miss was still substantial. Antenatal care is found to be protective against maternal near miss. Emphasizing antenatal care to prevent anemia and modifying other chronic medical conditions is recommended as prevention strategies. Avoiding primary cesarean section is recommended unless a clear indication is present. Finally, the country should place more emphasis on strategies for reducing MNM and its consequences, with the hope of improving women's health.

Prevalence and risk factors for newborn anemia in southwestern Uganda: a prospective cohort study

Introduction

The global prevalence of anemia in pregnancy is about 42%, and in sub-Saharan Africa, the prevalence of newborn anemia ranges from 25-30%. Anemia in newborn babies may cause complications such as delayed brain maturation and arrested growth. However, there is limited data on prevalence of newborn anemia and its risk factors in people living in resource-limited settings.

Objectives

We determined the prevalence and risk factors for newborn anemia and its correlation with maternal anemia in southwestern Uganda.

Methods

This was a prospective cohort study of 352 pregnant women presenting to Mbarara Regional Referral Hospital for delivery. We collected maternal blood in labor and umbilical cord blood from the placental vein, as a proxy for newborn hemoglobin. We estimated hemoglobin using a point-of-care Hemocue machine. We used summary statistics to characterize the cohort, and compared demographic characteristics and outcomes using Chi-square, t-test, and Wilcoxon Ranksum analyses. We defined newborn anemia as umbilical cord hemoglobin < 13g/dl and estimated the relationship between maternal and umbilical cord hemoglobin using linear regression analysis, adjusting for potential confounders.

Results

The prevalence of newborn anemia was 17%. The average maternal parity was significantly higher for anemic and non-anemic newborns (3.5 versus 2.8, P = 0.01). Mean age [SD] was significantly lower for participants with umbilical cord hemoglobin < 13g/dl than those > = 13 g/dl, (26 [5.6] versus 28 [6.3], P = 0.01). In multivariable linear regression analysis, a 1-point decrease in maternal hemoglobin was associated with a 0.14-point decrease in umbilical cord hemoglobin (P = 0.02). Each one-unit increase in maternal parity was associated with a 0.25-point decrease in umbilical cord hemoglobin (P = 0.01). Cesarean delivery was associated with a 0.46-point lower umbilical cord hemoglobin level compared to vaginal delivery (P = 0.03).

Conclusions

We found a significant correlation between maternal and newborn hemoglobin levels, underscoring the importance of preventing and correcting maternal anemia in pregnancy. Furthermore, maternal anemia should be considered a risk factor neonatal anemia.

Prevalence and Risk Factors of Anemia in the MASHAD Cohort Study

BACKGROUND

Anemia is a serious public health problem which may be associated with cardiovascular diseases (CVDs) and brain damage. This survey aims to determine the prevalence of anemia and its association with demographic and biochemical factors and metabolic syndrome in a human sample derived from the MASHAD cohort study.

METHODS

This survey was conducted on a sub-sample of 9847 individuals aged 35 to 65 as part of the MASHAD cohort study. Demographic characteristics and biochemical and anthropometrics indices were recorded. Data were analyzed using SPSS version 20.

RESULTS

Anemia was seen in 11.5% of the population. Anemia was significantly more prevalent in younger subject (P<0.001), females (P<0.001) and those with elevated body mass index (BMI) (P<0.001). Mean high-density lipoprotein (HDL) was higher in anemic participant (P=0.032). The incidence of anemia was significantly lower in smokers (P<0.001) and also participant with hypertension (HTN) (P<0.001), diabetes mellitus (DM) (P<0.001) and metabolic syndrome (MetS) (P<0.001). Mean FBG (P<0.001), TG (P<0.001), total cholesterol (P<0.001), LDL (P<0.001) and uric acid (P<0.001) were significantly lower in anemic subjects. Cholesterol, MetS, low-density lipoprotein (LDL), BMI, uric acid, diabetes mellitus and also TG remained significantly different after multivariate analysis between anemic and healthy participants.

CONCLUSION

The studied population had a lower prevalence of anemia compared to the previous WHO report for Iranians. Iron deficiency is recognized as the most important cause of anemia in Iran; however, further investigations will be need to confirm this pattern. We demonstrated that anemia is adversely associated with MetS and DM.

Current concepts in preoperative anemia management in obstetrics

PURPOSE OF REVIEW

The purpose of this article is to provide an overview of currently recommended treatment approaches for anemia during pregnancy, with a special focus on iron deficiency and iron deficiency anemia (IDA).

RECENT FINDINGS

As consistent patient blood management (PBM) guidelines in obstetrics are still lacking, recommendations regarding the timing of anemia screening and the treatment recommendations for iron deficiency and IDA during pregnancy are still controversial. Based on increasing evidence, early screening for anemia and iron deficiency should be recommended at the beginning of each pregnancy. To reduce maternal and fetal burden, any iron deficiency, even without anemia, should be treated as early as possible during pregnancy. While oral iron supplements administered every other day are the standard treatment in the first trimester, the use of intravenous iron supplements is increasingly suggested from the second trimester onwards.

SUMMARY

The treatment of anemia, and more specifically iron deficiency anemia during pregnancy, holds many possibilities for improvement. The fact that the period of risk is known well in advance and thus there is a long optimization phase is per se an ideal prerequisite for the best possible therapy of treatable causes of anemia. Standardization of recommendations and guidelines for screening and treatment of IDA in obstetrics is required for the future. In any case, a multidisciplinary consent is the precondition for a successfully implementation of anemia management in obstetrics to establish an approved algorithm easily enabling detection and treatment of IDA during pregnancy.

Preliminary Study of Iron Concentration in the Human Placenta in Twin Pregnancies

BACKGROUND

Pregnancy significantly increases the demand for iron (Fe) in the female body to facilitate maternal blood volume expansion, placental development, and fetal growth. As Fe flux in pregnancy is significantly influenced by the placenta, the aim of this study was to determine the dependencies between the Fe concentration in the placenta, the infant's morphometric parameters and the woman's morphological blood parameters in the last trimester.

METHODS

The study was conducted on 33 women with multiple (dichorionic-diamniotic) pregnancies from whom the placentas were drawn, and their 66 infants, including pairs of monozygotic (n = 23) and mixed-sex twins (n = 10). Fe concentrations were determined based on inductively coupled plasma atomic emission spectroscopy (ICP-OES) using ICAP 7400 Duo, Thermo Scientific.

RESULTS

The results of the analysis showed that lower placental Fe concentrations were associated with deteriorated morphometric parameters of infants, including weight and head circumference. Although we found no statistically significant dependencies between Fe concentration in the placenta and the women's morphological blood parameters, higher Fe concentration in the placenta of mothers supplemented with Fe correlated with better morphometric parameters in infants compared to those whose mothers received no Fe supplementation.

CONCLUSIONS

The research adds additional knowledge for placental iron-related processes during multiple pregnancies. However, many limitations of the study do not allow detailed conclusions to be assessed, and statistical data should be assessed conservatively.

Serum concentration of zinc, copper, iron, and its associated factors among pregnant women of small-scale farming in western Ethiopia

Micro-nutrients are required in small amounts to maintain growth and cell functioning to complete the life cycle through reproductions. However, pregnant women in developing countries like Ethiopia are vulnerable to multiple micro-nutrient deficiencies. Therefore, this study aimed at assessing the serum level of metals and associated factors like dietary diversity, and health-related problems in pregnant women among small-scale farming in Kellem Wellega, western Ethiopia. A cross-sectional laboratory-based study was conducted from June to August 2021 on 417 pregnant women attending antenatal care at rural healthcare facilities. Data was collected by using per-tested structured questionnaires via face-to-face interviews. The data analysis was conducted using SPSS version 24.0, and multivariate logistic regression analysis was performed to determine the association between predictor and outcome variables. A statistically significant was considered at p value < 0.05 for all the analyses. Our study findings showed that 62.1, 80.9, and 71.9% of the participants were deficient in iron, zinc, and copper micro-nutrient levels, respectively. Pregnant women who could not have formal education were 3.24 (AOR = 3.24, 95% CI 1.33-7.91) and 3.98 (AOR = 3.98, 95% CI 1.2-13.15) times more likely to show zinc and copper deficiency than those who attended secondary school and above, respectively. Furthermore, pregnant women involved only in farming activities were 0.57 (AOR = 0.57, 95% CI 0.36-0.91) and 4.33 (AOR = 5.72, 95% CI 2.34-13.97) times more likely to be exposed to iron and zinc deficiency than those who were engaged in other activities. This study revealed that pregnant women with low income were 6.36 times more likely to be exposed to zinc micro-nutrient deficiencies than those with high-income participants (AOR = 6.36, 95% CI 1.47-27.61). Additionally, those participants who ate a varied diet between 1 and 4 items per day were 2.26 (AOR = 2.26, 95% CI 1.43-3.59) and 2.77 (AOR = 2.77, 95% CI 1.6-4.61) times more likely to suffer zinc and copper micro-nutrient insufficiency than those who consumed 5-10 items per day. Finally, pregnant women who developed diarrhea in the past three months were 1.82 (AOR = 2.77, 95% CI 1.14-2.92) and 2.52 (AOR = 2.52, 95% CI 1.3-4.91) times more likely to be exposed to iron and copper deficiency than those who never show the symptoms, respectively. This study identified low concentrations of zinc, iron, and copper in the blood serum of pregnant women of small-scale farmers.

The Effectiveness of a Web-Based Application for a Balanced Diet and Healthy Weight Among Indonesian Pregnant Women: Randomized Controlled Trial

BACKGROUND

Pregnant women have self-declared that they have difficulties in estimating nutrient intakes. The Nutrition Information System for Indonesian Pregnant Women (SISFORNUTRIMIL) application was created as a dietary assessment and calorie-counting tool to guide pregnant women to eat the right portion sizes for each meal.

OBJECTIVE

The study aimed to examine the effectiveness of the SISFORNUTRIMIL application in helping users achieve a balanced diet and healthy maternal weight gain in comparison to nonusers in Indonesia.

METHODS

 First-pregnancy women in the second trimester aged 19-30 years (N=112) participated in the randomized controlled trial. Recruited women who were eligible and consented to participate in the study were allocated into the intervention group, or application user (n=56), and the control group, or application nonuser (n=56). The intervention recommended that pregnant women consume at least 5 food groups and calculate a recommended average portion size for 12 weeks. Both groups were self-monitored and recorded their intake in food records for 3 days every week. The dietary diversity consumed, macro- and micronutrient intake, and maternal weight gain were assessed pre- and postintervention. Data were collected three times during the intervention. Diversity food consumption was measured by the Minimum Dietary Diversity for Women of reproductive age. Furthermore, the Indonesian recommended dietary allowances were used to refer to and validate appropriate energy and nutrient amounts. Independent sample t test was used to compare differences between the intervention and control groups.

RESULTS

The mean dietary diversity score for the application user group (7.79, SD 1.20) was significantly greater than for the application nonuser group (7.02, SD 1.39; adjusted mean difference 0.77, 95% CI 0.28-1.25; d=0.28; P=.005). Macro- and micronutrient intake was significantly more in accordance with the dietary recommendations for the user group compared to the control group, including an energy daily intake of 156.88 kcal (95% CI 114.52-199.23; d=-1.39; P=.002), 102.43 g of carbohydrates (95% CI -125.2 to -79.60; d=-1.68; P=.02), 14.33 g of protein (95% CI 11.40-17.25; d=1.86; P<.001), and 10.96 g of fat (95% CI -13.71 to -8.20; d=-1.49; P<.001). Furthermore, there was a significantly higher intake of daily vitamins and minerals in the intervention group than in the control group. Other results showed that maternal weight gain in the intervention group was in accordance with the parameters of healthy weight gain.

CONCLUSIONS

 Recording food intake using the application was significantly effective in improving the dietary diversity consumed, improving adequate energy and nutrient intake, and producing healthy maternal weight during pregnancy.

Deworming utilization among pregnant mothers with at least one antenatal care follow-up in Ethiopia, 2022:- A multilevel analysis

BACKGROUND

Soil-transmitted helminthes (STHs) are the major public health problems that affect the health of pregnant women and their incoming newborns. In Ethiopia, about 33.35% of pregnant women were affected by these infections. Utilization of deworming medication during pregnancy is the main strategy endorsed by the World Health Organization (WHO) to reduce the burden of STH-induced anemia and its related complications. However, information related to the coverage and its individual as well as community-level factors on the utilization of deworming medication among pregnant mothers with at least one antenatal care (ANC) visit is limited in Ethiopia.

METHODS

A nationwide population-based cross-sectional study was conducted from January 18 to June 27, 2016. The information was obtained from the 2016 Ethiopian Demographic Health Survey (EDHS 2016), which can be accessed at: https://www.dhsprogram.com. A weighted sample of 4690 pregnant women selected using a two-stage stratified cluster sampling technique was included in the final analysis. A Multi-variable multilevel binary logistic regression model was fitted to identify the determinants of the utilization of deworming medication during pregnancy. Log-likelihood ration (LLR), deviance and Akaike's Information Criterion (AIC) were used to select the best fitted model in the multilevel analysis. Statistical significance was declared at p-value <0.05.

RESULT

From a total of 4690 mothers included in the final analysis, only 365 (7.8%) of them utilized deworming medication in pregnancy. After controlling for confounding effects, having four or more Antenatal care (ANC) visits, having functional working status, intake of iron folic acid (IFA) tablets and coming from a community with a low poverty level increases the odds of utilization of deworming medication during pregnancy.

CONCLUSION AND RECOMMENDATION

In this study, less than one in ten pregnant mothers takes deworming medication. Mothers with less than four ANC visits, who did not receive IFA tablets, who came from a community with a high poverty level, and mothers with no good functional status were at the greatest risk of not receiving deworming medication during pregnancy. Sustained efforts need to be undertaken to increase the socioeconomic status of the community and to scale up the health care utilization behaviors of pregnant mothers.

The impact of weight loss diet programs on anemia, nutrient deficiencies, and organ dysfunction markers among university female students: A cross-sectional study

Practicing restricted weight loss diet programs (WLDPs) without proper supervision can result in nutritional deficiency, which can lead to the development of several nutritional disorders. The current cross-sectional study aimed to investigate the impact of WLDPs practiced by university female students on the prevalence of micronutrient deficiencies, anemia, and organs dysfunction, and to assess the association of identified anomalies with dieting practices and dietary habits of university female students. A total of 185 (105 dieting and 80 non-dieting) volunteers’ female students at Al-Hussein Bin Talal University participated in this study. After the participants answered a questionnaire, blood samples were collected for hematological and biochemical analysis, and the body mass index (BMI) was determined. The results show that there were no significant differences between dieting and non-dieting groups in biochemical markers of kidney and liver functions as well as serum levels of copper, zinc, and folate. On the other hand, dieting participants exhibited significantly lower level of hemoglobin, serum ferritin, iron, and vitamin B12 than encounter group (p&lt;0.05). Attempting WLDPs significantly increased the prevalence of anemia (46.7%), iron deficiency (57.1%), and iron deficiency anemia (IDA) (41.9%), comparing to non-dieting students (28.7%, 33.8%, and 15.0%, respectively) (p&lt;0.005). Chi-square test showed that the development of anemia among dieting girls was significantly dependence of several factors including BMI category, source and duration of the diet programs, and skipping breakfast (p&lt;0.05). In conclusion, young girls attempting WLDPs without professional guidance are more prone to the risk of nutrients deficiencies and the development nutritional disorders like IDA. An educational program should be employed to teach young females on when and how to adopt healthy WLDPs.

A Retrospective Study of Various Iron Preparations Oral Administration in Pregnant Women with Iron Deficiency Anemia

During pregnancy anemia is a common medical condition, with iron deficiency and megaloblastic anemia being the most common. The symptoms range from very mild to severe and if left without proper medical treatment, there can be serious consequences for both mother and fetus. The most frequent pregnancy problem is anemia. The term "Iron Deficiency Anemia" refers to erythropoiesis under conditions of absolute iron deficiency. This presupposes the depletion of iron stores in the body. Iron deficiency anemia or Sideropenic anemia is the most common form of anemia worldwide. Special attention must be given to nutrition during pregnancy. In the current retrospective study, it was evaluated the contribution of various iron preparations substitution during the pregnancy and puerperium.

Potentially harmful medication use and the associated factors among pregnant women visiting antenatal care clinics in Mbarara Regional Referral Hospital, Southwestern Uganda

Background

Pregnancy management using medications has been challenging for both healthcare providers and pregnant women, given the fear of teratogenicity effects and the potential for fetal harm. In the developing world, poor health-seeking behavior of patients, delayed initiation of antenatal care (ANC), and low level of educational status of mothers could contribute to the issue of drug safety in pregnancy.

Aim

The aim of the study was to determine the prevalence and factors associated with potentially harmful medication use in pregnancy.

Methods

A cross-sectional study was conducted from April 1 to June 6, 2021, including 209 pregnant women on ANC follow-up at a referral hospital in Southwestern Uganda. The simple random sampling technique was employed to select study participants. Interviewer-administered questionnaires were used to collect the history of medication use since conception and then the participant's ANC card was reviewed to determine prescribed drug regimens and their indications. Statistical Package for the Social Sciences version 23.0 was used for analysis.

Results

Out of the 1,422 medications used by 209 women, 665 (42.2%) were category C, and 182 (11.5%) were category A. A total of 92 (44.0%) pregnant women used at least one potentially harmful medication during the current pregnancy. Having more than average monthly income (adjusted odds ratio [aOR] = 2.32 [1.04, 5.14 at 95% confidence interval (CI)]), having a chronic disease (aOR = 3.24 [1.17, 8.97 at 95% C.I]), using 7 and more medications (aOR = 9.12 [4.11, 20.24 at 95% CI]), and use of herbal medicines (aOR = 4.50 [2.10, 9.87 at 95% CI]) were shown to be risk factors.

Conclusion

The proportion of pregnant women that used at least one potentially harmful medication is higher than in previous studies. Having comorbidities and taking more medications increase the risk of receiving a potentially harmful medication during pregnancy.

Relevance to Patients

This study identified the gaps in the use of medicines during pregnancy which will enable the development and implementation of protocols for optimizing prescribing practices in pregnant women by focusing on the safety of the fetus.

Spontaneous hemothorax in pregnant patient with pulmonary arteriovenous malformation

We present a case of a 34-year-old pregnant patient at 26 weeks' gestation by in vitro fertilization with past medical history of hypertension and infertility who presented to the hospital with abdominal pain. The patient stated her pain was in her left upper quadrant. The morning before arriving to the hospital the patient stated she woke up at 0300 with increasingly severe pain in the same area. A computed tomography angiogram of the chest demonstrated a left-sided pulmonary arteriovenous malformation with adjacent complex left effusion on chest suspicious for a hemothorax. The hemothorax was thought to be brought about by rupture of the arteriovenous malformation with likely intermittent small volume hemorrhages into the pleural space. Thoracic Surgery and Interventional radiology (IR) were each consulted for management of the arteriovenous malformation. Due to the patient's stable hemodynamic status and concern that an invasive procedure might enable a larger rupture and more substantial hemorrhage, the decision was made for embolization of the arteriovenous malformation.

Effectiveness of Dietary Interventions in Prevention and Treatment of Iron-Deficiency Anemia in Pregnant Women: A Systematic Review of Randomized Controlled Trials

Pregnant women are among the population groups most vulnerable to the development of anemia, as the overall iron requirement during pregnancy is significantly higher than in non-pregnant women. The aim of the systematic review was to assess the effectiveness of dietary interventions in the prevention and treatment of iron-deficiency anemia in pregnant women based on randomized-controlled trials. The systematic review was based on the PRISMA guidelines and is registered in the PROSPERO database (CRD42021261235). The search was conducted within PubMed and Web of Science databases for the period until June 2021. The included randomized controlled trials presented effectiveness of dietary interventions in prevention and treatment of iron-deficiency anemia in pregnant women. From the total number of 7825 screened records, the final number of seven studies were included in the systematic review. The procedure of screening, inclusion, reporting, and assessment of the risk of bias while using the revised Cochrane risk of bias tool for randomized trials was conducted by two independent researchers. The studies included in the systematic review were conducted in populations of anemic pregnant women, or mixed populations of anemic and non-anemic pregnant women. The interventions described within the studies were associated with including fortified products, regular products, or dietary counselling. They were based on providing an increased amount of iron, providing an increased amount of multiple nutrients, or general counselling only, while effectiveness was compared with effectiveness of the placebo, supplementation, or control group. The study duration was diversified from a few weeks to half a year or longer. The major biochemical measure assessed within the included studies was hemoglobin. All applied dietary interventions, based on providing increased amount of iron, providing increased amount of multiple nutrients, or general counselling only, were effective. The majority of included studies were assessed as ones of a medium risk of bias. For some studies a high risk of bias was indicated, which resulted from a risk of bias arising from the randomization process, due to deviations from the intended interventions, and in selection of the reported result. Considering this fact, more randomized controlled trials should be planned and conducted in a rigorous manner to confirm the formulated observations of effectiveness of the studied interventions based on providing an increased amount of iron, providing an increased amount of multiple nutrients, or general counselling only.

Screening, Treatment, and Monitoring of Iron Deficiency Anemia in Pregnancy and Postpartum

Iron deficiency anemia is the most prevalent form of anemia worldwide. In the United States, clinicians routinely screen for iron deficiency anemia upon initiation of prenatal care, at the start of the third trimester, and prior to birth. Treatment of iron deficiency anemia generally begins with oral supplementation of elemental iron, which is associated with adverse gastrointestinal effects. These adverse effects can decrease adherence, leading to subtherapeutic treatment. Newer evidence highlights the benefits of early screening for iron deficiency before the onset of anemia, as well as the use of intravenous iron to expedite the treatment of iron deficiency anemia. More research is needed on the potential consequences of over-supplementation and iron deficiency without anemia to guide treatment. This article reviews the evidence for best practices for screening, treatment, and continued monitoring of iron deficiency anemia during pregnancy and postpartum. Maternal, fetal, and neonatal implications are reviewed, as well as the risks and benefits of treatment options. Finally, an evidence-based algorithm is proposed to guide clinicians on continued monitoring after treatment.

Prevalence of iron deficiency anemia in Brazilian women of childbearing age: a systematic review with meta-analysis

BACKGROUND

Iron deficiency anemia (IDA) is among the most common micronutrient deficiencies in women of childbearing age and may affect children's development. Brazil has several national programs to tackle this condition, such as food fortification and supplementation for pregnant women, but IDA prevalence in this population has not been systematically reviewed. We sought to determine the prevalence of IDA in Brazilian women of childbearing age through a systematic review with metanalysis.

METHODOLOGY

A protocol was previously published on the PROSPERO platform under the code CRD42020200960. A panel of the National Council for Scientific and Technological Development (CNPq) approved the protocol of this study under the public call number 26/2019. The main databases searched were MEDLINE, Web of Science, Scopus, Lilacs, and SciELO. In gray literature, the Brazilian Digital Library of Theses and Dissertations and the annals of the Brazilian Congress of Epidemiology and the Brazilian Congress of Public Health were accessed. The search strategy involved terms related to the condition (IDA) and the age group of the population of interest (teenagers and adults). Studies that had assessed the prevalence of IDA in Brazilian women of childbearing age (10-49 years) were included. Three independent reviewers read all titles and abstracts and extracted data from the included studies. Random effects meta-analyses using the Freeman-Tukey arcsine transformation were carried out with prevalence data, and meta-regression was conducted to test for subgroup differences. The quality of the studies was assessed using the Newcastle-Ottawa Scale.

RESULTS

From 21,210 unique records screened, 237 full-texts were retrieved, of which 91 were included in the qualitative synthesis, and 83 were included in the meta-analysis. The overall IDA prevalence was 25% (95% CI [23-28], 83 studies). The subgroup of studies that used random sampling showed a prevalence of 22% (95% CI [17-27], 22 studies), whereas in those with non-random sampling, the prevalence was 27% (95% CI [23-30], 61 studies), without significant differences between subgroups in the metaregression (P = 0.13). High prevalence of IDA were found in the subgroups of studies conducted in the North and Northeast regions (30%; 95% CI [24-37]; seven studies, and 30%; 95% CI [26-34]; 27 studies, respectively), in studies conducted with indigenous population (53%; 95% CI [27-78], four studies), and with studies that had their collections after 2015 (28%; 95% CI [23-34], nine studies).

CONCLUSIONS

IDA in women of childbearing age remains a public health problem in Brazil, especially in the North and Northeast region. The national programs should be strengthened and more thoroughly supervised to decrease this condition nationally.

The Influence of Nutritional Supplementation for Iron Deficiency Anemia on Pregnancies Associated with SARS-CoV-2 Infection

Anemia is a very common occurrence during pregnancy, with important variations during each trimester. Anemia was also considered as a risk factor for severity and negative outcomes in patients with SARS-CoV-2 infection. As the COVID-19 pandemic poses a significant threat for pregnant women in terms of infection risk and access to care, we developed a study to determine the impact of nutritional supplementation for iron deficiency anemia in correlation with the status of SARS-CoV-2 infection. In a case-control design, we identified 446 pregnancies that matched our inclusion criteria from the hospital database. The cases and controls were stratified by SARS-CoV-2 infection history to observe the association between exposure and outcomes in both the mother and the newborn. A total of 95 pregnant women were diagnosed with COVID-19, having a significantly higher proportion of iron deficiency anemia. Low birth weight, prematurity, and lower APGAR scores were statistically more often occurring in the COVID-19 group. Birth weight showed a wide variation by nutritional supplementation during pregnancy. A daily combination of iron and folate was the optimal choice to normalize the weight at birth. The complete blood count and laboratory studies for iron deficiency showed significantly decreased levels in association with SARS-CoV-2 exposure. Puerperal infection, emergency c-section, and small for gestational age were strongly associated with anemia in patients with COVID-19. It is imperative to screen for iron and folate deficiency in pregnancies at risk for complications, and it is recommended to supplement the nutritional intake of these two to promote the normal development and growth of the newborn and avoid multiple complications during pregnancy in the COVID-19 pandemic setting.

Reticulocyte Hemoglobin Equivalent: Diagnostic Performance in Assessment of Iron Deficiency in Patients with Hypothyroidism

Introduction

Iron deficiency affects approximately 30% of the world population and is frequently encountered in hypothyroid patients. Early recognition and prompt treatment of iron deficiency in hypothyroid patients lead to a favorable outcome. The aim of this study is to prove the usefulness of reticulocyte hemoglobin equivalent (Ret-He) as a reliable and effective tool in diagnosis of iron deficiency in hypothyroid patients.

Materials and Methods

154 patients with hypothyroidism were included in the study. They were divided into 4 groups. Group 1 included 66 hypothyroid patients without iron deficiency. They were taken as controls. Group 2 included 66 hypothyroid patients with iron deficiency anemia (IDA). Group 3 included 12 hypothyroid patients with iron deficiency but without anemia (ID). Group 4 included 10 hypothyroid patients which had concomitant iron deficiency with anemia of chronic disorder (ACDC). Ret-He was measured by analyzing blood samples on System XN 350. Thyroid profile, serum ferritin, and biochemical data were measured by an automated analyzer. Statistical analysis was performed by using SPSS 23.

Results

Ret-He was significantly lower with (p < 0.001) in group 2 (hypothyroid patients with IDA), group 3 (hypothyroid patients with ID), and in group 4 (hypothyroid patients with ACDC) as compared to controls in group 1 (hypothyroid patients without iron deficiency). After ROC analysis area under the curve (AUC) of Ret-He for hypothyroid patients with IDA was 0.96 at cutoff 28.5 pg with sensitivity of 93% and specificity of 90%. AUC of Ret-He in the hypothyroid group with ACDC was 0.99 at cutoff 30.8 pg with sensitivity of 90% and specificity of 90%. AUC of Ret-He in hypothyroid patients with ID was 0.97 at cutoff 31.7 pg with sensitivity of 91% and specificity of 70%.

Conclusion

Ret-He is a reliable, rapid, and cost-effective tool for diagnosing iron deficiency in hypothyroid patients.

Role of fermented goat milk as a nutritional product to improve anemia

Goat milk, like cow milk, needs some modifications to be used as the sole source of nutrition during early infancy. For goat milk to be more like human milk and more nutritionally complete, sugar, vitamins and minerals need to be added to it and for reduction of renal solute load, it needs to be diluted. To prevent megaloblastic anemia in infants fed exclusively on goat milk, folic acid should be supplied either by adding it to goat milk or by an oral folic acid supplement. In fortification of milk products, thermal processing, fermentation, and species differences in milk folate bioavailability are three additional factors that should be considered besides absolute difference in folate concentration between goat and human milk. Whether different feeding regimes (e.g., iron and folate content of diets) influence milk folate content needs to be elucidated by more research. Our findings showed that fermented goat milk during anemia recovery can be improve antioxidant status, protection from oxidative damage to biomolecules, protective effects on testis, improve Fe and skeletal muscle homeostasis as well as improve cardiovascular health. PRACTICAL APPLICATIONS: To be used as part of a postweaning nutritionally well-balanced diet, fermented goat milk is most likely an excellent source of nutrition for the human.

Dietary association of iron deficiency anemia and related pregnancy outcomes

Iron deficiency anemia (IDA) is a common public health occurrence of pregnancy which is particularly prevalent in developing countries like Pakistan. During this critical period, the deficiency of iron is very common as the iron requirements are greatly enhanced. IDA during pregnancy is associated with intrauterine growth retardation, premature birth, low birthweight, increased labor time, higher risk of infection, elevated maternal and prenatal mortality, muscle dysfunction, and low physical capacity. The present study was aimed to check the prevalence, effect of diet on IDA and its association with the pregnancy outcome, that is, birthweight. Five different public sector hospitals of Rawalpindi and Islamabad were analyzed. A sample size of 500 pregnant females of third trimester was observed which were then followed after delivery from September 2020 to January 2021. A well-designed questionnaire was developed where different demographic factors, dietary recalls, biomarkers, and other determinants were obtained. The data from the questionnaires were later coded for the purpose of analysis in the statistical package (SPSS) using chi-square test. Our study indicated that IDA is a moderate public health problem among pregnant women in twin cities and more than half of study subjects have depleted iron stores. Approximately 63% of the subjects were having iron deficiency and 24.8% were facing severe iron deficiency anemia. Only 12% of the subjects were considered as normal. The high prevalence of anemia in our subjects was probably due to low iron intake and poor dietary habits. The results of the study may not be generalizable due to time constraints and other factors. Maternal anemia still remains a major public health concern that requires more attention especially in developing and underdeveloping countries.

Liposomal ferric pyrophosphate and ascorbic acid supplementation in pregnant women with iron deficiency anaemia: haematochemical, obstetric, neonatal and psychological outcomes in a prospective observational study

This study aimed to determine the effects of liposomal iron pyrophosphate/ascorbic acid on clinical and psychological outcomes in pregnant women. Women at the 11th-13th weeks of gestation with iron deficiency anaemia assuming Sideremil™ from April 2018 to May 2019 were recruited. Haematochemical, obstetric, neonatal and psychological outcomes were investigated at the enrolment, 21-23 weeks of gestation, 30-32 weeks of gestation and after 6 weeks from childbirth. Results showed significant positive effects on haemoglobin, ferritin, sideremia and transferrin levels, compared to baseline data. A significant improvement of anxiety and depression levels was also observed. Regarding the quality of life, all the domains significantly improved, especially the Physical Role domain. Our results indicate that Sideremil^™ may be a valid treatment for iron deficiency anaemia in pregnant women, since it significantly improves haematological and mental health outcomes. However, further studies are needed to confirm these results.

Incidence, Management and Outcomes in Women Undergoing Peripartum Hysterectomy in a Tertiary Care Centre in India

Background Peripartum hysterectomy (PRH) is the surgical removal of the uterus performed in obstetrical complications such as uncontrolled postpartum haemorrhage (PPH), unrepairable uterine rupture, and sepsis. Its incidence has increased in recent years. The objective of this study was to review all the cases of PRH in a tertiary care teaching hospital over three years (January 2017-December 2019) to determine its incidence and analyse clinico-demographic characteristics in these women. Method All women undergoing PRH from January 2017 to December 2019 were included in the study. Data were collected retrospectively from medical records, of patients who underwent a PRH at the time of delivery, or within 24 hours, or performed any time before discharge from the same hospitalization and obstetric event. The total number of deliveries including caesarean and vaginal deliveries were recorded. Main outcome measures were the incidence of PRH, indication for hysterectomy, management option used, maternal outcomes (PPH, bladder injury and maternal death) and fetal outcomes (stillbirth). Results There were a total of 3904,4 deliveries; 27,337 vaginal and 11,697 caesarean sections in three years. A total of 50 patients underwent a PRH. The incidence of PRH in our study was 1.3 per 1,000 deliveries and 3.5/1,000 caesareans, respectively. PRH was found to be more common following cesarean sections than vaginal deliveries (odds ratio 22.86 [95% CI: 8.16 to 63.98]). Morbid adherent placenta (MAP) (n=30, 62%) was the most common indications of PRH. Seven (15%) women had PRH due to uterine rupture. Twenty-seven women of the 30 women (90%) with the MAP had a previous caesarean delivery. The case fatality rate per hysterectomy was 4%. Stillbirth rate (SBR: n=8,16%) among women having PRH was seven-fold higher than overall SBR in our country. Conclusion There has been a rise in MAP as an indication of PRH in our study for a decade in comparison to uterine atony. Caesarean delivery is a significant risk factor for PRH. Previous caesarean section and major placenta previa were common occurring obstetric risk factors present in the MAP in our cohort. Our maternal mortality in PRH was low and the stillbirth rate was high when compared with national data.
