Determinants of Hemoglobin Among Pregnant Women at Agro-Pastoralist Communities in South Omo Zone, Ethiopia: Community Based Cross-Sectional Study, Nutrition Experience from Movable Community

Background

Low hemoglobin level is the most common public health problem during pregnancy in developing countries including Ethiopia, which is affecting both mother and fetus. However, the determinants of anemia among pregnant women are not well studied.

Objective

To assess the determinates of hemoglobin among pregnant women in rural agro-pastoralist communities in the South Omo zone, Ethiopia.

Method

Community-based cross-sectional study was done in rural agro-pastoralist communities. A multistage stratified sampling technique was used to select 526 pregnant women. Data were collected by using structured questionnaires. Hemoglobin level was measured by using HemoCue ® Hb301. Data were analyzed by using a statistical package for the social science version 26. Descriptive (Mean, standard deviation, frequency, range), bivariate and multivariate analysis was carried out to check the association between lower hemoglobin levels and independent variables. The output is presented in tables and figures.

Result

The mean (±SD) of hemoglobin concentration was 11.8 ± 1.7. The overall prevalence of anemia was 39.9% [95% CI: 35.5, 44.4], 19.4% (95% CI: 16.0, 23.2) was mild, 19.6% (95% CI: 16.27, 2.5) was moderate and 0.9% (95% CI: 0.25, 2.25) was severe anemia. Not taking IFA (AOR = 5.7(3.3, 9.8)), severe under nutrition (AOR = 8.9(2.1, 37.3)), no fish food (AOR = 2.4(1.3, 4.5)), drinking coffee (AOR = 1.6(1.0, 2.6)), moderate food insecurity (AOR = 2.5(1.4, 4.6)), and no malaria infection (AOR = 0.6(0.4, 0.9)) were statistically significant with anemia.

Conclusion

The anaemia is a public health problem in this study area. Therefore, nutrition education and counselling to enhance iron supplementation, dietary diversity and a flesh diets are very essential to enhance haemoglobin levels.

The influence of hematological profiles on the transfusion management and mortality risk of mothers presenting to the obstetric unit of a South African tertiary medical facility

BACKGROUND

Laboratory results are frequently abnormal in pregnant mothers. Abnormalities usually relate to pregnancy or associated complications. Hematological abnormalities and age in pregnancy may increase the likelihood for transfusion and mortality.

STUDY DESIGN AND METHODS

Hematological profiles and transfusion history of pregnant mothers presenting to a tertiary hospital, were evaluated over 2 years. Age, anemia, leukocytosis and thrombocytopenia were assessed for transfusion likelihood. Iron deficiency and coagulation were assessed in transfused patients. Anemia, leukocytosis, thrombocytopenia, human immunodeficiency virus (HIV) and transfusion were assessed for mortality likelihood.

RESULTS

There were 12,889 pregnant mothers included. Mothers <19-years-old had the highest prevalence of anemia (31.5%) and proportion of transfusions (19%). The transfusion likelihood was increased in mothers with anemia (odds ratios [OR] = 6.41; confidence intervals at 95% [95% CI] 5.46-7.71), leukocytosis (OR = 2.35; 95% CI 2.00-2.76) or thrombocytopenia (OR = 2.71; 95% CI 2.21-3.33). Mothers with prolonged prothrombin times received twice as many blood products as their normal counterparts (p = .03) and those with iron deficiency anemia five times more blood products (p < .001). Increased likelihood for mortality was seen in patients with anemia (OR = 4.15, 95% CI 2.03-8.49), leukocytosis (OR = 2.68; 95% CI 1.19-6.04) and those receiving blood transfusion (OR = 3.6, 95% CI 1.75-7.47).

DISCUSSION

Adolescence, anemia, leukocytosis and thrombocytopenia expose mothers to a high risk for transfusion and/or mortality. These risk factors should promptly trigger management and referral of patients. Presenting hematological profiles are strong predictors of maternal outcome and transfusion risk.

Changes in time structure of periodic leg movements during sleep in restless legs syndrome: Effects of sex and age

BACKGROUND

The objective of this study was to check the hypothesis that in women with restless legs syndrome (RLS) different changes occur in periodic leg movements during sleep (PLMS) during the post-menopausal period (using >50 years as a proxy) than in men of the same age.

METHODS

We recruited 36 untreated patients aged 18-50 years (19 men, median age 40 years, and 17 women, median age 37 years) while the remaining 67 were >50 years old (24 men, median age 66.6 years, and 43 women, median age 60.0 years). Leg movement activity during sleep was analyzed by means of an approach utilizing indexes especially suitable to assess leg movement periodicity.

RESULTS

No significant difference was seen between men in the two age groups; conversely, in women, a clear and significant increase in Periodicity Index was observed in the older group, along with a decrease in isolated leg movements. In women, a clear age-related enhancement of PLMS was found in the intermovement interval graphs, especially in the 16-22 s range, which was more evident than that observed in men. The results remained unchanged also when they were replicated by selecting only subjects aged 18-45 years vs. those aged >55 years.

CONCLUSIONS

Our findings indicate that assessing PLMS in women after menopause is clinically relevant because they are probably connected with the hormonal fluctuations of this period of life. Translationally, identifying and addressing PLMS in post-menopausal women is crucial for optimizing their sleep health and addressing potential health risks associated with sleep disturbances.

Anemia and iron deficiency in pregnant women with rheumatic diseases

INTRODUCTION

Anemia and iron deficiency are the most common pathologies in pregnancy and associated with adverse pregnancy outcome. As patients with rheumatic diseases are also at high risk for anemia, we aimed to investigate the frequency of anemia and iron deficiency during pregnancy in this group and whether anemia is a risk factor for adverse maternal or child outcome.

METHODS

We analyzed 368 pregnancies from a German registry for pregnancies in patients with rheumatic diseases (TURIRE) from 2014-2022. Anemia and iron deficiency were defined according to the World Health Organization. Main outcome measures were prevalence of anemia, iron deficiency, and adverse outcomes.

RESULTS

From the 368 patients 61% were diagnosed with a connective tissue disease, 16% with rheumatoid arthritis or juvenile idiopathic arthritis, 14% with spondyloarthritis, 3% with vasculitis and 7% with other. Prevalence of anemia/iron deficiency was 18%/28% in the first, 27%/51% in the second and 33%/62% in the third trimester. Low hemoglobin levels (OR 0.52) or iron deficiency (OR 0.86) had a negative impact on child outcome. However, lower hemoglobin levels were associated with a lower risk for maternal complications (OR 1.47).

CONCLUSION

Prevalence of anemia and iron deficiency is high in pregnant women with rheumatic diseases. Compared to previously published cohorts of the general population from different countries, the prevalence of anemia and iron deficiency is distinctly higher. Furthermore, patients with rheumatic diseases already start with impaired iron storage and/or hemoglobin levels. Thus, iron supplementation should be initiated early on in this vulnerable in this patient group.

The Ferritin, Hepcidin and Cytokines Link in the Diagnoses of Iron Deficiency Anaemia during Pregnancy: A Review

Following a diagnosis of iron deficiency anaemia in pregnancy, iron supplements are prescribed using UK guidelines; however, despite this, the condition remains highly prevalent, affecting up to 30% of pregnant women in the UK. According to the World Health Organisation, it globally accounts for 45% in the most vulnerable groups of pregnant women and infants (<5 years old). Recently, the efficacy of iron replacement therapy and the effectiveness of current standard testing of iron parameters have been reviewed in order to evaluate whether a more accurate diagnosis can be made using alternative and/or supplementary markers. Furthermore, many questions remain about the mechanisms involved in iron metabolism during pregnancy. The most recent studies have shed more light on serum hepcidin and raised questions on the significance of pregnancy related inflammatory markers including cytokines in iron deficiency anaemia. However, research into this is still scarce, and this review aims to contribute to further understanding and elucidating these areas.

Association of a pro-inflammatory diet and gestational diabetes mellitus with maternal anemia and hemoglobin levels during pregnancy: a prospective observational case-control study

Anemia is prevalent in pregnant women, and the causes include inadequate diet, increased demand for iron, and inflammation. We hypothesized that gestational diabetes mellitus (GDM) and hepcidin-related gene polymorphisms may contribute to maternal anemia and that an anti-inflammatory diet can alleviate this negative effect. The aim of this study was to investigate the association of an inflammatory diet, GDM, and single nucleotide polymorphisms (SNPs) in hepcidin-related genes, which are key regulators of iron, with maternal anemia. This was a secondary data analysis of a prospective prenatal diet and pregnancy outcome study in Japan. The Energy-Adjusted Dietary Inflammatory Index was calculated using a brief self-administered diet history questionnaire. We analyzed 121 SNPs in 4 genes: TMPRS6 (43 SNPs), TF (39 SNPs), HFE (15 SNPs), and MTHFR (24 SNPs). Multivariate regression analysis was conducted to determine the association between the first variable and maternal anemia. The prevalence of anemia in first, second, and third trimesters were 5.4%, 34.9%, and 45.8%, respectively. The pregnant women with GDM had a significantly higher incidence of moderate anemia than those without GDM (40.0% vs. 11.4%, P = .029). In multivariate regression analysis, Energy-adjusted Dietary Inflammatory Index (β = -0.057, P = .011) and GDM (β = -0.657, P = .037) were significantly associated with hemoglobin levels during the third trimester. Using Stata's qtlsnp command, TMPRSS6 rs2235321 was found to be associated with hemoglobin levels during the third trimester. These results indicate that inflammatory diets, GDM, and TMPRSS6 rs2235321 polymorphism are associated with maternal anemia. This result suggests that a pro-inflammatory diet and GDM are associated with maternal anemia.

Preoperative anemia and associated factors in women undergoing cesarean section at a comprehensive specialized referral hospital in Ethiopia

Background

Anemia is a common public health burden during pregnancy. Severe maternal and fetal complications have been associated with anemia. Despite many studies on anemia during pregnancy have been conducted in Ethiopia at any time of antenatal care visits, the prevalence of preoperative anemia among women awaiting cesarean delivery and its contributing factors have not been determined. The aim of this study was to determine the prevalence and associated factors of preoperative anemia in women awaiting cesarean section at a comprehensive specialized hospital in Ethiopia.

Methods

An institution-based cross-sectional study was done from April to June 2022 to determine preoperative anemia in women undergoing cesarean delivery. Data were obtained using a standardized questionnaire that included the women’s background characteristics. Bi-variable and multi-variable logistic regression analyses were performed to identify variables related to preoperative anemia. With a 95% confidence level, the estimated crude odds ratio and adjusted odds ratio were calculated. In a multivariate analysis, variables were considered statistically significant if their p-value was less than 0.05.

Results

A total of 424 pregnant women with a 100% response rate were included in this study. The prevalence of preoperative anemia among women awaiting cesarean delivery was 28.3% (95% CI: 23.8–32.5%). Previous history of abortion, lack of iron supplementation, human immunodeficiency virus infection, previous cesarean section, and American Society of Anesthesiology class III were significantly associated with preoperative anemia among women awaiting cesarean section.

Conclusion and recommendation

Preoperative anemia was diagnosed in a significant proportion of women awaiting cesarean-delivery. Anemia was linked to a lack of iron supplementation, American Society of Anesthesiology class III, previous history of abortion, human immunodeficiency virus infection, and previous cesarean section. Therefore, early detection of high-risk pregnancies, iron supplementation, prevention of HIV infection and due attention to people living with HIV/AIDs are paramount.

Prevalence and risk factors of anemia in first, second and third trimesters of pregnancy in Iran: A systematic review and meta-analysis

Anemia is a common health problem during pregnancy worldwide that has many short-term and long-term effects on women. This study examined the Prevalence and Risk factors of anemia in first, second and third trimesters of pregnancy in Iran between 2000 and 2021. PubMed, Medline, Scopus, Google Scholar, and national databases of Magiran and SID were searched for articles, which were then subjected to PRISMA-compliant screening. A systematic review and meta-analysis (using a random-effects model in STATA version 17) were conducted on the 18 eligible cross-sectional studies (published between July 23, 2000 and September 1, 2021) that revealed significant data on the prevalence of anemia in pregnant women. This study included 18 reports with a total of 25,831 individuals in which 15% of study subjects had anemia (95% CI: 12-19%). The pooled prevalence of anemia was 13% in people older than 26 years old (95% CI: 9-17%) compared to 22% in people younger than 26 years old (95% CI: 15-29). It was 18% (95% CI: 11-27%) for pregnant women having their second child in comparison to 20% (95% CI: 11-32%) for women who have had three or more children. Anemia was thought to affect 11% of housewives (95% CI: 2-26%) and 10% of working women (95% CI: 6-16%). Anemia frequency was 22%, 17% and 13% amongst first (22%), second (17%), and third (13%) trimesters, respectively. Nevertheless, it happened much less often after the second trimester. Moreover, poor education, a history of low birth weight in children, and a low socioeconomic level within women were associated with the prevalence of anemia. The pooled prevalence of anemia in pregnant women is marginally lower than in earlier report. However, it seems to be a health problem in developing countries including Iran currently. Therefore, the study suggest that health system should design comprehensive preventive and control measurements such as more effective treatments to minimize anemia in vulnerable segments of society, particularly mothers, and improve their health through increasing access to services for mothers.

Analysis of Renal Pathology Predictors in Tender-Age Infants: Cohort Study

Background. The early onset of nephropathies creates certain risk of early chronic kidney disease development with loss of function (especially in children with unfavorable intrauterine period), renal tissue dysplasia, congenital malformations and/or urodynamic disorders.

Objective. The aim of the study is to evaluate the role of ontogenesis factors in nephropathies development in tender-age infants with specification of the course features and kidneys morphometric parameters.

Methods. Cohort study was conducted. The study group included 69 children aged from 0 to 36 months with changes in the kidneys (compared to age-specific ones) according to ultrasound and/or urinary syndrome (leukocyturia, bacteriuria, proteinuria, etc.). The control group included 35 relatively healthy children of the same age. Comparative analysis of antenatal and postnatal medical history was carried out in both groups, as well as comparison of morphometric indicators of the urinary system organs at neonatal ultrasound screening. Pathological process onset was also considered in the group of children with nephropathies. The study was conducted during 2018–2021.

Results. Possible predictors of pathology process in children with early onset of nephropathies are: 1) maternal diseases: urinary system disorders (OR = 4.99), blood pathology, mainly anemia of the 2nd–3rd grade (OR = 6.94), cardiovascular system diseases (OR = 10.26), inflammatory diseases of genital tract (OR = 10.61); 2) pregnancy failures: gestational diabetes mellitus (OR = 7.24), preeclampsia and eclampsia (OR = 4.40); placental pathology (OR = 17.0), and fetoplacental insufficiency (OR = 7.61); 3) feeding features: early conversion to breast-milk substitutes (OR = 2.81). 50.7% of children of this group has shown persistent urodynamic disorders already at first months of life according to ultrasound data, as well as signs of bloated kidneys. It was shown that the inflammatory process manifestation associated with aggravated perinatal history and congenital defects occurs significantly earlier — 2 months, and without any defects — 4 months (p = 0.004).

Conclusion. Burdened antenatal and neonatal medical history has negative effect on the morphogenesis of the urinary system organs and creates conditions for early nephropathies development during the first months of life.

The relationship between anemia and obesity

INTRODUCTION

Obesity is linked to a variety of unfavourable outcomes, including anaemia, which is a serious global public health problem. The prevalence of obesity along with anaemia suggests a relationship between obesity and anaemia. Recent studies have demonstrated strong associations between anaemia and obesity, chronic diseases, ageing, hepato-renal impairment, chronic infection, autoimmune diseases, and widespread malignancy. Thus, the intersection point of obesity and anaemia is an important area of attention.

AREA COVERED

This paper reviews the pathophysiology of obesity and anaemia. Then, It deliberates the relationship between obesity and different types of anaemia and other clinical forms associated with anaemia.

EXPERT OPINION

Obesity, especially obesity-related to excessive visceral fat distribution, is accompanied by several disturbances at the endothelial, hormonal, and inflammatory levels. These disturbances induce activation of several mechanisms that contribute to the anaemic state. Over-weight patients with chronic anaemias are required to maintain the related vitamins and minerals at optimum levels and appropriate BMI. In addition, a regular clinical follow-up is essential to be scheduled to reduce the risk of complications associated with anaemia in obese patients.

Beneficios del uso del hierro parenteral como alternativa eficaz en el manejo de la anemia gestacional en Colombia

Introducción. La Organización Mundial de la Salud (OMS) estima que más del 40% de las mujeres embarazadas a nivel mundial tienen anemia, y la mitad de estas padecen deficiencia de hierro. La prevalencia en América Latina es del 40% y en Colombia del 44.7%. Fisiológicamente en el embarazo se produce una mal llamada “anemia dilucional”, existen condiciones en la embarazada que la predisponen a tener una anemia patológica. Esta última es causada principalmente por un déficit de hierro, de allí la importancia de diagnosticar a tiempo esta entidad e iniciar el manejo. La administración de hierro es la base del tratamiento de la anemia por deficiencia de hierro. Puede ser administrado por vía oral, la cual es la preferida en la mayoría de las pacientes; sin embargo, cuando este no es posible administrarlo, es esencial recurrir al hierro parenteral. No obstante, el hierro parenteral es poco usado como primera línea en el manejo de la anemia gestacional. El presente artículo tiene como objetivo realizar una revisión que permita identificar la terapia con hierro parenteral como una alternativa eficaz de manejo para la anemia gestacional, teniendo en cuenta las características farmacológicas, la administración y el uso entre las diferentes moléculas disponibles en Colombia. Metodología. Corresponde a un estudio de revisión de literatura en bases de datos y bibliotecas electrónicas, los criterios que se tuvieron en cuenta fueron textos publicados entre 1996 y 2020, en español e inglés.

Maternal hereditary hemolytic anemia and birth defects in the National Birth Defects Prevention Study

OBJECTIVES

Hereditary hemolytic anemia (HHA) results from genetic mutations that cause red blood cell abnormalities. Little research exists on the relationship between HHA and birth defects. Using data from the National Birth Defects Prevention Study (NBDPS), we described characteristics of HHA-exposed women and estimated associations between HHA during pregnancy and specific birth defects.

METHODS

The NBDPS was a population-based, case-control study of major birth defects and included pregnancies with estimated delivery dates from October 1997 through December 2011. Participants were ascertained from hospital discharge lists or birth defect registries at 10 sites. Trained interviewers collected information about pregnancy exposures via telephone questionnaire. We described characteristics among HHA-exposed women and calculated crude odds ratios and exact 95% confidence intervals for defects with ≥3 exposed cases.

RESULTS

Among 31 HHA-exposed women (28 cases/3 controls), 13 (42%) reported sickle cell anemia, 17 (55%) reported thalassemia, and one (3%) reported hereditary spherocytosis. The average age at delivery for HHA-exposed case women was 27.3 years (range: 17-38). The majority (82%) of HHA-exposed case women reported additional conditions during pregnancy, including hypertension, genitourinary infections, and respiratory illnesses. Additionally, 93% of case women reported using medication during pregnancy. Among the 28 cases, 18 (64%) had isolated birth defects. The defects with ≥3 exposed cases were anencephaly, atrial septal defect, gastroschisis, and cleft palate. Except for anencephaly, the 95% confidence intervals for all estimates were close to or included the null.

CONCLUSION

This hypothesis-generating study adds to the sparse literature on the association between HHA and birth defects.

Evaluating test utilization for anemia during pregnancy

OBJECTIVE

To evaluate, using longitudinal laboratory data, potential care gaps, and the prevalence of anemia in pregnant women residing in New Mexico, USA.

METHODS

A total of 985 pregnant women aged 13-60 were included from December 1, 2018 to December 1, 2019. Parameters included frequency of CBC, iron studies, reticulocyte panel, prevalence of anemia, iron deficiency anemia (IDA), iron deficiency (ID), anemia change throughout pregnancy, and ICD-10 codes utilization.

RESULTS

CBC was completed in 896/985 (91%) of the sample population in the first trimester and 528/985 (53.6%) in the third trimester. Two hundred and fifty-two (25.6%) women had anemia at any given point during pregnancy. ID was prevalent in 1.3% of women in the first trimester and 1.0% in the third, while IDA was prevalent in 0.4% in their first trimester and 5.5% in the third. Data also show an overall worsening of anemia from first to third trimester (2.8% and 40.9%, respectively, p < .0001). A positive correlation was found between mean corpuscular volume (MCV) and reticulocyte hemoglobin (RET-He) (r = .8592, 95% CI 0.7475 to 0.9237).

CONCLUSION

Test utilization for anemia screening during pregnancy can be improved to guide patient management to reduce anemia rate and potential anemia-associated complications.

Gestational Anemia and its effects on neonatal outcome, in the population of Hyderabad, Sindh, Pakistan

Background

Anemia in pregnancy is a globally health-related issue, that affects both mothers and their newborn. Anemia during pregnancy across the world involves approximately 38% of the world population. To evaluate the effect of gestational anemia on perinatal outcome in the population. The aim of present study is to evaluate the effect of gestational anemia on perinatal outcome in the population of Hyderabad, Sindh, Pakistan.

Methods

A cross-sectional comparative analysis was conducted among pregnant mothers who were listed to give birth at Liaquat University of medical and health sciences Jamshoro/Hyderabad during the period of September 2018 to September 2019. The study population 400 were selected by convenient random sampling, and grouped into 2 on the basis of their Hb levels, with Hb < 11 gm% they were classified as anemic mothers, Hb ≥ 11 gm% were termed as non-anemic mothers, data was collected on the preformed questionnaire, and was analyzed on SPSS 21.

Results

The prevalence of anemia was 51.5% in in total population out of which, the incidence of normocytic normochromic anemia was highest 52.4 %microcytic hypochromic anemia was found in 19.4%, Overall, extremely low Apgar was found in 53 anemics, and 8 non. anemic mother’s infants, LBW incidence was 47.5 %; in anemic mothers, and 15.4 % in non-anemic group, the term, small for gestational age infants were 14.5% in anemic mothers, and 3.6% in non-anemic mothers, there were 36 preterm births to anemic mothers and 10 in non-anemic mothers. The incidence of caesarian section is 53.3% in anemic mothers compared to 30.9% in non-anemic mothers.

Conclusions

Anemia in pregnancy significantly increases risks of low Apgar, LBW, term SGA, preterm birth, and an increase incidence of caesarian section.

Investigation of the risk factors of anorectal malformations

PURPOSE

To investigate the factors that influence the occurrence of anorectal malformations (ARMs).

METHODS

From December 2018 to December 2019, 136 children treated for ARMs at the Children's Hospital of Chongqing Medical University were included in the case group. The control group consisted of children with intussusception or perianal abscesses. A uniform questionnaire was filled by the parents of the enrolled children.

RESULTS

The birth weight of the cases was significantly lower than that of the controls (p < .01), and children with ARMs were more likely to be complicated with single umbilical artery (SUA) (p < .001). Maternal upper respiratory tract infection (adjusted odds ratio [OR_adj ], 2.44; 95% confidence interval [CI], 1.29-4.63) and urogenital infection (OR_adj , 2.67; 95% CI 1.11-6.38) during the first trimester of pregnancy, anemia during pregnancy (OR_adj , 5.69; 95% CI, 1.01-32.07), and exposure to hazardous substances 6 months before pregnancy and during the first trimester of pregnancy (OR_adj , 13.82; 95% CI, 3.86-49.35) are associated with increased risk of ARMs. Folic acid supplements (OR_adj , 0.31; 95% CI, 0.14-0.65) and multivitamin (OR_adj , 0.34; 95% CI, 0.15-0.79) had a protective effect on ARMs. Paternal drug use (OR_adj , 9.17; 95% CI, 2.19-38.49) 6 months before their wives' conception increased the risk of ARMs.

CONCLUSION

Maternal infection, anemia during pregnancy, and maternal hazardous substances exposure are possible risk factors for ARMs. Folic acid supplements and multivitamin can reduce the occurrence of ARMs. Meanwhile, paternal drug use may also be a risk factor for ARMs.

Breast cancer and pregnancy: Why special considerations prior to treatment are needed in multidisciplinary care

Breast cancer diagnosed during pregnancy poses ethical and professional challenges. Clinical management of that condition should ensure the safety of both the mother and fetus. Clinical trials on breast cancer exclude pregnant women, so sufficient evidence with which to formulate guidelines for the management of these patients is lacking. Failing to undergo a breast examination during pregnancy, breast symptoms explained by physiological changes such as pregnancy, and unnecessary abortions after the diagnosis of breast cancer lead to worse outcomes for these patients. Multidisciplinary teams including breast surgeons, obstetricians, radiologists, pathologists, and anesthesiologists need to make an early diagnosis and comprehensively evaluate patients in different gestational weeks and with different stages of breast cancer in order to optimize outcomes.

Impact of Anemia in Pregnant Women on the Neonatal Conditions

Background. One of the most prevalent illnesses in the world is anemia. Anemia in pregnant women has been a pressing obstetric issue for many years and is one of the most common complications of pregnancy in the world, particularly in developing countries. Aim. To study the condition of neonates born to women with anemia during pregnancy. Methods. A retrospective analysis of 230 patients' medical records in maternity and pregnancy pathology departments. The patients were divided into 2 groups: Group 1 consisted of patients suffering from iron deficiency anemia, Group 2 comprised patients without iron deficiency anemia. Results. The height-to-weight ratio in the group of neonates born to mothers with anemia statistically was significantly lower compared to the control group. The proportion of neonates with hypotrophy in the group born to mothers with anemia statistically was significantly higher. Body length and birth condition indices assessed according to the APGAR scale were virtually identical across the groups. Conclusions. Anemia during pregnancy affects the trophism of a fetus, which is largely reflected in the health of neonates. Treating maternal anemia is important to prevent or decrease the incidence of underweight in infants at birth.

Association of gestational anemia with pregnancy conditions and outcomes: A nested case-control study

BACKGROUND

Gestational anemia is a serious public health problem that affects pregnant women worldwide. Pregnancy conditions and outcomes might be associated with the presence of gestational anemia. This study investigated the association of pregnancy characteristics with anemia, exploring the potential etiology of the disease.

AIM

To assess the association of pregnancy parameters with gestational anemia.

METHODS

A nested case-control study was conducted based on the Chinese Pregnant Women Cohort Study-Peking Union Medical College Project (CPWCS-PUMC). A total of 3172 women were included. Patient characteristics and gestational anemia occurrence were extracted, and univariable and multivariable logistic regression models were used to analyze the association of pregnancy parameters with gestational anemia.

RESULTS

Among the 3172 women, 14.0% were anemic, 46.4% were 25-30 years of age, 21.9% resided in eastern, 15.7% in middle, 12.4% in western 18.0% in southern and 32.0% in northern regions of China. Most women (65.0%) had a normal prepregnancy body mass index. Multivariable analysis found that the occurrence of gestational anemia was lower in the middle and western regions than that in the eastern region [odds ratio (OR) = 0.406, 95% confidence interval (CI): 0.309-0.533, P < 0.001)], higher in the northern than in the southern region (OR = 7.169, 95%CI: 5.139-10.003, P < 0.001), lower in full-term than in premature births (OR = 0.491, 95%CI: 0.316-0.763, P = 0.002), and higher in cases with premature membrane rupture (OR=1.404, 95%CI: 1.051-1.876, P = 0.02).

CONCLUSION

Gestational anemia continues to be a health problem in China, and geographical factors may contribute to the situation. Premature birth and premature membrane rupture may be associated with gestational anemia. Therefore, we should vigorously promote local policy reformation to adapt to the demographic characteristics of at-risk pregnant women, which would potentially reduce the occurrence of gestational anemia.

The interactive effects of non-alcoholic fatty liver disease and hemoglobin concentration in the first trimester on the development of gestational diabetes mellitus

Gestational diabetes mellitus (GDM) is associated with adverse perinatal and maternal outcomes. Epidemiological studies have reported that non-alcoholic fatty liver disease (NAFLD) and a high hemoglobin (Hb) concentration are risk factors for GDM in the middle trimester. However, no consistent conclusions have been reached, especially in Chinese pregnant women. A case-control study was conducted to better understand the associations between NAFLD and Hb concentration in the first trimester and the risk of GDM and their interactive effects. Multivariable logistic regression analysis and a cross-product term of Hb and steatosis were used to evaluate the associations between first trimester Hb concentration, steatosis, and GDM and their interactive effects. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using two-sided statistical tests at an alpha level of 0.05. For the study, 1,017 normal pregnant women, and 343 pregnant women diagnosed with GDM (25.22%) were recruited from the First Hospital of Shanxi Medical University, Shanxi Province, China. NAFLD-associated steatosis was found to be independent risk factors for developing GDM compared with grade 0 steatosis, with ORs of 1.98 (95% CI: 1.35–2.89) and 2.27 (95% CI:1.29–3.96), respectively. Meanwhile, a high Hb concentration was found to be a risk factor for developing GDM compared with the normal Hb concentration (OR = 1.88; 95% CI:1.24–2.83). The risk of developing GDM was more pronounced among pregnant women who had both high-grade steatosis and higher Hb concentrations during their first trimester (OR = 6.24; 95% CI: 1.81–23.66). However, we found no significant interactions between Hb concentration and steatosis grade. In conclusion, our study confirmed that a high Hb concentration and NAFLD-associated steatosis during the first trimester play important roles in predicting the risk of GDM in Chinese women. Future studies are required to verify the interactive effects between NAFLD-associated steatosis and Hb concentration.

Association of higher HbA1c within the normal range with adverse pregnancy outcomes: a cross-sectional study

OBJECTIVE

The aim of this study was to investigate the association between a relatively high HbA1c level within the normal range and the risk of adverse pregnancy outcomes.

METHODS

This retrospective cohort study was conducted between March 2018 and March 2019 at Women's Hospital, School of Medicine, Zhejiang University. Multiple logistic regression models after adjusting for plausible confounders were implemented to assess the relationships between the level of HbA1c and adverse pregnancy outcomes.

RESULTS

A total of 8585 women were included in our study. The rates of preterm birth, macrosomia and preeclampsia were 4.4% (380/8585), 5.3% (457/8585) and 1.7% (149/8585), respectively. After adjusting for potential confounding variables, an HbA1c range of 5.5-5.9% (37-41 mmol/mol) remained significantly associated with an increased risk of preterm delivery (a-OR 2.27; 95% CI, 1.50-3.43), macrosomia (a-OR 1.97; 95% CI, 1.32-2.94) and preeclampsia (a-OR 3.70; 95% CI, 2.07-6.60). GDM-negative pregnant women with an HbA1c level in the range of 5.5-5.9% (37-41 mmol/mol) had an increased risk of preterm delivery (a-OR 2.84; 95% CI, 1.71-4.71) and preeclampsia (a-OR 3.82; 95% CI, 1.81-8.04). However, GDM-positive pregnant women had an increased risk of macrosomia (a-OR 2.12; 95% CI, 1.13-3.97) and preeclampsia (a-OR 2.62; 95% CI, 1.01-6.81).

CONCLUSION

A higher HbA1c level within the normal range is an independent risk factor for preterm delivery and preeclampsia, especially among GDM-negative women. Therefore, relevant medical staff should enhance the awareness of risk and prevention to strengthen pregnancy monitoring.

Predictors of iron consumption for at least 90 days during pregnancy: Findings from National Demographic Health Survey, Pakistan (2017-2018)

BACKGROUND

Iron supplementation is considered an imperative strategy for anemia prevention and control during pregnancy in Pakistan. Although there is some evidence on the predictors of iron deficiency anemia among Pakistani women, there is a very limited understanding of factors associated with iron consumption among Pakistani pregnant women. Thus, this study aimed to investigate the predictors of iron consumption for at least ≥90 days during pregnancy in Pakistan.

METHODS

We analyzed dataset from the nationally representative Pakistan Demographic Health Survey 2017-2018. The primary outcome of the current study was the consumption of iron supplementation for ≥90 days during the pregnancy of the last birth. Women who had last childbirth 5 years before the survey and who responded to the question of iron intake were included in the final analysis (n = 6370). We analyzed the data that accounted for complex sampling design by including clusters, strata, and sampling weights.

RESULTS

Around 30% of the women reported consumed iron tablets for ≥90 days during their last pregnancy. In the multivariable logistic regression analysis, we found that factors such as women's age (≥ 25 years) (adjusted prevalence ratio (aPR) = 1.52; 95% CI: 1.42-1.62)], wealth index (rich/richest) (aPR = 1.25; [95% CI: 1.18-1.33]), primary education (aPR = 1.33; [95% CI: 1.24-1.43), secondary education (aPR = 1.34; [95% CI: 1.26-1.43), higher education (aPR = 2.13; [95% CI: 1.97-2.30), women's say in choosing husband (aPR = 1.68; [95% CI: 1.57-1.80]), ≥ five antenatal care visits (aPR =2.65; [95% CI (2.43-2.89]), history of the last Caesarian-section (aPR = 1.29; [95% CI: 1.23-1.36]) were significantly associated with iron consumption for ≥90 days.

CONCLUSION

These findings demonstrate complex predictors of iron consumption during pregnancy in Pakistan. There is a need to increase the number of ANC visits and the government should take necessary steps to improve access to iron supplements by targeting disadvantaged and vulnerable women who are younger, less educated, poor, and living in rural areas.

A birth population-based survey of preterm morbidity and mortality by gestational age

Background

Despite 15–17 millions of annual births in China, there is a paucity of information on prevalence and outcome of preterm birth. We characterized the outcome of preterm births and hospitalized preterm infants by gestational age (GA) in Huai’an in 2015, an emerging prefectural region of China.

Methods

Of 59,245 regional total births, clinical data on 2651 preterm births and 1941 hospitalized preterm neonates were extracted from Huai’an Women and Children’s Hospital (HWCH) and non-HWCH hospitals in 2018–2020. Preterm prevalence, morbidity and mortality rates were characterized and compared by hospital categories and GA spectra. Death risks of preterm births and hospitalized preterm infants in the whole region were analyzed with multivariable Poisson regression.

Results

The prevalence of extreme, very, moderate, late and total preterm of the regional total births were 0.14, 0.53, 0.72, 3.08 and 4.47%, with GA-specific neonatal mortality rates being 44.4, 15.8, 3.7, 1.5 and 4.3%, respectively. There were 1025 (52.8% of whole region) preterm admissions in HWCH, with significantly lower in-hospital death rate of inborn (33 of 802, 4.1%) than out-born (23 of 223, 10.3%) infants. Compared to non-HWCH, three-fold more neonates in HWCH were under critical care with higher death rate, including most extremely preterm infants. Significantly all-death risks were found for the total preterm births in birth weight <  1000 g, GA < 32 weeks, amniotic fluid contamination, Apgar-5 min < 7, and birth defects. For the hospitalized preterm infants, significantly in-hospital death risks were found in out-born of HWCH, GA < 32 weeks, birth weight <  1000 g, Apgar-5 min < 7, birth defects, respiratory distress syndrome, necrotizing enterocolitis and ventilation, whereas born in HWCH, antenatal glucocorticoids, cesarean delivery and surfactant use decreased the death risks.

Conclusions

The integrated data revealed the prevalence, GA-specific morbidity and mortality rate of total preterm births and their hospitalization, demonstrating the efficiency of leading referral center and whole regional perinatal-neonatal network in China. The concept and protocol should be validated in further studies for prevention of preterm birth.

Anemia in Ugandan pregnant women: a cross-sectional, systematic review and meta-analysis study

Background

Anemia in pregnancy represents a global public health concern due to wide ranging maternal and neonatal adverse outcomes in all peripartum periods. We estimated the prevalence and factors associated with anemia in pregnancy at a national obstetrics and gynecology referral hospital in Uganda and in addition performed a systematic review and meta-analysis of the overall burden of anemia in pregnancy in Uganda.

Methods

We conducted a cross-sectional study among 263 pregnant women attending the antenatal care clinic of Kawempe National Referral Hospital, Kampala, Uganda, in September 2020. Anemia in pregnancy was defined as a hemoglobin level of < 11.0 g/dl and microcytosis as a mean corpuscular volume (MCV) of < 76 fL. We also performed a systematic review (PROSPERO Registration ID: CRD42020213001) and meta-analysis of studies indexed on MEDLINE, Embase, African Journal Online, ClinicalTrials.gov, ICTRP, and the Cochrane Library of systematic review between 1 January 2000 and 31 September 2020 reporting on the prevalence of anemia in pregnancy in Uganda.

Results

The prevalence of anemia was 14.1% (n= 37) (95%CI 10.4–18.8), of whom 21 (56.8%) had microcytic anemia. All cases of anemia occurred in the second or third trimester of pregnancy and none were severe. However, women with anemia had significantly lower MCV (75.1 vs. 80.2 fL, p<0.0001) and anthropometric measurements, such as weight (63.3 vs. 68.9kg; p=0.008), body mass index (25.2 vs. 27.3, p=0.013), hip (98.5 vs. 103.8 cm, p=0.002), and waist (91.1 vs. 95.1 cm, p=0.027) circumferences and mean systolic blood pressure (BP) (118 vs 125 mmHg, p=0.014). Additionally, most had BP within the normal range (59.5% vs. 34.1%, p=0.023). The comparison meta-analysis of pooled data from 17 published studies of anemia in pregnancy in Uganda, which had a total of 14,410 pregnant mothers, revealed a prevalence of 30% (95% CI 23–37).

Conclusions

Despite our study having a lower prevalence compared to other studies in Uganda, these findings further confirm that anemia in pregnancy is still of public health significance and is likely to have nutritional causes, requiring targeted interventions. A larger study would be necessary to demonstrate potential use of basic clinical parameters such as weight or blood pressure as screening predictors for anemia in pregnancy.

Dialysis on Pregnancy: An Overview

Pregnancy rates in women on dialysis have increased in the last decades, thus making it a topic of growing interest. The rarity of this event is predominantly due to fertility problems and to the high rates of pregnancy failure including stillbirth, fetal, and neonatal deaths. We conducted a narrative review of existing literature in order to analyze the major issues about pregnancy on dialysis to give the reader a fully updated perspective about this topic which, even if not common, is becoming more and more frequent. Even if recently acquired knowledge has improved diagnosis and treatment of dialysis pregnancies focusing on several aspects, pregnancy on dialysis remains a great challenge for obstetricians and should be managed by a multidisciplinary expertise team. Dialysis in pregnancy may be necessary for women previously affected by end stage renal disease (ESRD) becoming pregnant, or in case of acute renal injury presenting for the first time during gestation or, again, in case of existent renal pathology worsening during pregnancy and requiring dialysis. Although some evidence suggests that more intensive dialysis regimens are correlated with better obstetric outcomes, the optimal therapeutic protocol still remains to be established.

Vegetarian diets during pregnancy: effects on the mother's health. A systematic review

While interest in vegetarian nutrition has been steadily increasing, some aspects have not yet been consistently investigated. One topic requiring evidence-based confirmation is the adoption of a vegetarian diet during pregnancy and lactation. Maternal diet is not only correlated with the fetus's and infant's health, but appears relevant for that of the mother as well. Not only is an adequate delivery of nutrients to the fetus and infant mandatory, but the increased physiological needs of the maternal body require an adequate supply of nutrients and can represent harmful stress events that may lead to well-defined pathological conditions. In this review, we aim to systematically investigate state-of-the-art of vegetarian diets during pregnancy and lactation, focusing on maternal nutritional status and pregnancy outcomes. Data are scarce, often inconsistent and not homogeneous for many of the topics we considered, mainly because only a few studies have been performed in developed countries, whereas other studies have derived from developing countries, where vegetarianism can be a proxy indicator of malnutrition. For this reason, we did not find sufficient data to provide evidence-based information and recommendations. To date, the available literature does not clearly support a negative impact on the mother's health and pregnancy outcomes, but, analogously with the findings in the vegetarian adult population, an improvement in the quality of studies might facilitate finding more information on the possible positive impact of well-planned vegetarian diets during pregnancy and lactation. More epidemiological and interventional studies are warranted, in order to address the question as to whether vegetarian nutrition represents an advantage for the mother or poses nutritional issues that need further attention.

Benefits and Risks of IgG Transplacental Transfer

Maternal passage of immunoglobulin G (IgG) is an important passive mechanism for protecting the infant while the neonatal immune system is still immature and ineffective. IgG is the only antibody class capable of crossing the histological layers of the placenta by attaching to the neonatal Fc receptor expressed at the level of syncytiotrophoblasts, and it offers protection against neonatal infectious pathogens. In pregnant women with autoimmune or alloimmune disorders, or in those requiring certain types of biological therapy, transplacental passage of abnormal antibodies may cause fetal or neonatal harm. In this review, we will discuss the physiological mechanisms and benefits of transplacental transfer of maternal antibodies as well as pathological maternal situations where this system is hijacked, potentially leading to adverse neonatal outcomes.

Nutrition care for chronic kidney disease during pregnancy: an updated review

Cases of chronic kidney disease (CKD), including CKD in pregnant women, have increased globally in recent years. CKD during pregnancy is associated with a higher risk of adverse outcomes, including gestational hypertension, preeclampsia, intrauterine growth restriction, and preterm birth, among others. Nutrition plays a significant role in many metabolic and physiological changes during pregnancy. Women with CKD are at increased risk of nutrition deficiencies and metabolic issues than women without CKD. Currently, we lack evidence regarding metabolic and nutritional adaptations during pregnancy in women with CKD and how these adaptations relate to perinatal outcomes. In this review, dietary and supplementation recommendations for CKD in adults and pregnant women are summarized from current clinical guidelines. We present the main nutrition care practices that have been studied in CKD pregnancies. This review will be helpful to health professionals as a preliminary reference for nutrition assessment and therapy in pregnant women with CKD.

Iron Sucrose: A Wealth of Experience in Treating Iron Deficiency

Iron deficiency and iron-deficiency anemia are associated with increased morbidity and mortality in a wide range of conditions. In many patient populations, this can be treated effectively with oral iron supplementation; but in patients who are unable to take or who do not respond to oral iron therapy, intravenous iron administration is recommended. Furthermore, in certain conditions, such as end-stage kidney disease, chronic heart failure, and inflammatory bowel disease, intravenous iron administration has become first-line treatment. One of the first available intravenous iron preparations is iron sucrose (Venofer®), a nanomedicine that has been used clinically since 1949. Treatment with iron sucrose is particularly beneficial owing to its ability to rapidly increase hemoglobin, ferritin, and transferrin saturation levels, with an acceptable safety profile. Recently, important new data relating to the use of iron sucrose, including the findings from the landmark PIVOTAL trial in patients with end-stage kidney disease, have been reported. Several years ago, a number of iron sucrose similars became available, although there have been concerns about the clinical appropriateness of substituting the original iron sucrose with an iron sucrose similar because of differences in efficacy and safety. This is a result of the complex and unique physicochemical properties of nanomedicines such as iron sucrose, which make copying the molecule difficult and problematic. In this review, we summarize the evidence accumulated during 70 years of clinical experience with iron sucrose in terms of efficacy, safety, and cost-effectiveness.

Autoimmune hemolytic anemia in pregnancy: a challenge for maternal and fetal follow-up

Background: Autoimmune hemolytic anemia (AIHA) is a rare entity during pregnancy. The fetal risk is determined primarily by the ability of autoantibodies to cross the placental barrier. Currently, the establishment of a standardized antenatal care in cases with AIHA remains as a pending issue.Cases: Firstly, we describe a case of a 17-week pregnant woman that was diagnosed with cold agglutinin mediated (C3 and IgM) AIHA. Treatment was started with prednisone, showing initial improvement, but requiring intravenous gammaglobulins at 27 weeks. During the fetal follow-up, all studies showed normal results. In the third trimester, when there was a clinic and analytic maternal improvement, an unexpected fetal death occurred. Secondly, we present a case of a 30-week pregnant woman, diagnosed with warm antibody (IgG) AIHA. Despite the ability of IgG to cross the placental barrier, the serial measurements of the Middle Cerebral Artery (MCA) peak systolic velocity were always normal and childbirth occurred at term without any adverse perinatal outcome.Conclusion: During pregnancy, identification of the type antibodies in AIHA is crucial to estimate the potential maternal and fetal risks and to establish the follow-up. The interaction of the complement cascade with the coagulation cascade could be an explanation for a perinatal adverse outcome despite the inability of the IgM to cross the placental barrier.

Blood Products in the Management of Abnormal Placentation

A critical tool in the successful management of patients with abnormal placentation is an established massive transfusion protocol designed to rapidly deliver blood products in obstetrical and surgical hemorrhage. Spurred by trauma research and an understanding of consumptive coagulopathy, the past 2 decades have seen a shift in volume resuscitation from an empiric, crystalloid-based method to balanced, targeted transfusion therapy. The present article reviews patient blood management in abnormal placentation, beginning with optimizing the patient's status in the antenatal period to the laboratory assessment and transfusion strategy for blood products at the time of hemorrhage.

Presumed immune-mediated haemolytic anaemia associated with pregnancy in a cat

Case summary

A 7-year-old female entire Birman presented with acute-onset haemorrhagic vulvar discharge. Moderate, normocytic, normochromic, non-/pre-regenerative anaemia, along with a moderate mature neutrophilia, were seen on haematology. Saline test for agglutination was positive. No haemotropic mycoplasmas were identified. Serum biochemistry revealed severe hyperbilirubinaemia. Retroviral testing was negative. Serology for toxoplasmosis revealed a titre of 1:512. Abdominal ultrasound identified a large uterus, containing at least three advanced-stage fetuses, two of which failed to exhibit independent motion or cardiac activity. Ovariohysterectomy was performed. Histology demonstrated mild, multifocal suppurative placentitis, with Gram staining revealing no evidence of bacteria. Complete resolution of the anaemia was seen within 1.5 months of ovariohysterectomy.

Relevance and novel information

Immune-mediated haemolytic anaemia (IMHA) in association with pregnancy has not been previously reported in cats. This case represents a potential novel cause for IMHA in cats, which resolved following ovariohysterectomy.

Hospital-Based Study of Maternal, Perinatal and Neonatal Outcomes in Adolescent Pregnancy Compared to Adult Women Pregnancy

BACKGROUND

Adolescent pregnancy, defined as a pregnancy in girls aged 10 to 19 years. Adolescent mothers are at high risk for maternal and neonatal complications.

AIM

To compare maternal, perinatal and neonatal outcomes in adolescents and adult women aged 20-24 years.

MATERIAL AND METHODS

This retrospective cohort study included all singleton pregnancies during a three-year period (January 2016-December 2018) who gave birth in a Clinical Hospital in Tetovo, Republic of Macedonia. After exclusion criteria, a total of 932 cases were reviewed and divided into two groups: one of the teenage mothers (< 19 years old) (115 women) and the other of adult mothers (20-24 years old) (817 women).

RESULTS

Of the total number of 5643 births, 128 (2.27%) were from adolescent pregnancies. Of them, nulliparous adolescent women were 115 (2.04%). Adolescents compare to adult mothers had a higher rate of urinary tract infections (33% vs. 22%), increased rate of maternal anemia (26% vs. 15%), preterm birth, small for gestational age newborns (25.2% vs. 17.1%), lower high school attendance (0 vs. 21.9%) and inadequate prenatal care. Spontaneous labour was more common in adolescents (73% vs 63.5%), while Caesarean sections were less common than in women aged 20-24 years (25.2% vs 33.5%). The rate of other perinatal outcomes was not significantly different between the 2 groups.

CONCLUSIONS

The results of the study showed that the frequencies of some maternal, perinatal and neonatal complications were considerably higher in adolescent mothers.

Maternal anemia and pediatric neurological morbidity in the offspring - Results from a population based cohort study

OBJECTIVE

Maternal anemia (Hemoglobin, <11 mg/dl) has been shown to affect fetal growth and pregnancy outcome. We aimed to study a possible association between maternal anemia and the risk for neurological morbidity in the offspring, during a follow-up period of up to 18 years.

STUDY DESIGN

A population-based cohort analysis was performed at the Soroka University Medical Center (SUMC), a single regional tertiary center comparing total and specific subtypes of neurological morbidities associated with hospitalizations among children stratified by three maternal post-partum hemoglobin categories: ≥11 mg/dl (no anemia); 11.0 mg/dl > Hb ≥ 7 mg/dl (mild-to-moderate anemia) and <7 mg/dl (severe anemia). Data on pregnancy course and outcome, and later offspring hospitalizations, were compared between the three study groups. All singleton deliveries between the years 1991-2014 were included in the analysis, and congenital malformations were excluded. A Kaplan-Meier survival curve was used to compare cumulative hospitalization incidence based on maternal anemia status, and a Weibull survival multivariable hazard model was constructed to adjust for confounding variables.

RESULTS

The study population included 217,358 deliveries of which 50.6% were in mothers who were not anemic, 49.0% in mothers with moderate anemia and 0.4% in mothers with severe anemia. During the follow up period (0-18 years, median 10.22 years), 2.1% of offspring were hospitalized with a neurological diagnoses. Neurological hospitalization incidence decreased from 2.95/1000 person years, in the severe anemia group, to 2.32/1000 person years and 2.01/1000 person years, among the mild-to-moderate and no anemia groups, respectively (p = 0.007). The association between maternal anemia and offspring long-term pediatric neurological morbidity remained significant in a Weibull hazards model controlled for gestational age, delivery mode, SGA and insufficient prenatal care (adjusted HR 1.55; 1.05-2.31 and adjusted HR 1.13; 1.06-1.20; among the severe and mild-to-moderate anemia, vs. no anemia, respectively).

CONCLUSION

Children born to anemic mothers are at an increased risk for pediatric neurological-related hospitalizations.

Vegan Nutrition for Mothers and Children: Practical Tools for Healthcare Providers

As the number of subjects choosing vegan diets increases, healthcare providers must be prepared to give the best advice to vegan patients during all stages of life. A completely plant-based diet is suitable during pregnancy, lactation, infancy, and childhood, provided that it is well-planned. Balanced vegan diets meet energy requirements on a wide variety of plant foods and pay attention to some nutrients that may be critical, such as protein, fiber, omega-3 fatty acids, iron, zinc, iodine, calcium, vitamin D, and vitamin B12. This paper contains recommendations made by a panel of experts from the Scientific Society for Vegetarian Nutrition (SSNV) after examining the available literature concerning vegan diets during pregnancy, breastfeeding, infancy, and childhood. All healthcare professionals should follow an approach based on the available evidence in regard to the issue of vegan diets, as failing to do so may compromise the nutritional status of vegan patients in these delicate periods of life.

Guidelines for Antenatal and Preoperative care in Cesarean Delivery: Enhanced Recovery After Surgery Society Recommendations (Part 1)

This Enhanced Recovery After Surgery (ERAS) Guideline for perioperative care in cesarean delivery will provide best practice, evidenced-based, recommendations for preoperative, intraoperative, and postoperative phases with, primarily, a maternal focus. The focused pathway process for scheduled and unscheduled cesarean delivery for this ERAS Cesarean Delivery Guideline will consider from the time from decision to operate (starting with the 30-60 minutes before skin incision) to hospital discharge. The literature search (1966-2017) used Embase and PubMed to search medical subject headings that included "Cesarean Section," "Cesarean Section," "Cesarean Section Delivery" and all pre- and intraoperative ERAS items. Study selection allowed titles and abstracts to be screened by individual reviewers to identify potentially relevant articles. Metaanalyses, systematic reviews, randomized controlled studies, nonrandomized controlled studies, reviews, and case series were considered for each individual topic. Quality assessment and data analyses that evaluated the quality of evidence and recommendations were evaluated according to the Grading of Recommendations, Assessment, Development and Evaluation system, as used and described in previous ERAS Guidelines. The ERAS Cesarean Delivery Guideline/Pathway has created a maternal focused pathway (for scheduled and unscheduled surgery starting from 30-60 minutes before skin incision to maternal discharge) with ERAS cesarean delivery consensus recommendations preoperative elements (anesthetic medications, fasting, carbohydrate supplementation, prophylactic antibiotics/skin preparation, ), intraoperative elements (anesthetic management, maternal hypothermia prevention, surgical technique, hysterotomy creation and closure, management of peritoneum, subcutaneous space, and skin closure), perioperative fluid management, and postoperative elements (chewing gum, management of nausea and vomiting, analgesia, timing of food intake, glucose management, antithrombotic prophylaxis, timing of ambulation, urinary management, and timing of maternal and neonate discharge). Limited topics for optimized care and for antenatal education and counselling and the immediate neonatal needs at delivery are discussed. Strong recommendations for element use were given for preoperative (antenatal education and counselling, use of antacids and histamine, H2 receptor antagonists, 2-hour fasting and small meal within 6 hours surgery, antimicrobial prophylaxis and skin preparation/chlorhexidine-alcohol), intraoperative (regional anesthesia, prevention of maternal hypothermia [forced warm air, warmed intravenous fluids, room temperature]), perioperative (fluid management for euvolemia and neonatal immediate care needs that include delayed cord clamping), and postoperative (fluid management to prevent nausea and vomiting, antiemetic use, analgesia with nonsteroidal antiinflammatory drugs/paracetamol, regular diet within 2 hours, tight capillary glucose control, pneumatic compression stocking for venous thromboembolism prophylaxis, immediate removal of urinary catheter). Recommendations against the element use were made for preoperative (maternal sedation, bowel preparation), intraoperative (neonatal oral suctioning or increased inspired oxygen), and postoperative (heparin should not be used routinely venous thromboembolism prophylaxis). Because these ERAS cesarean delivery pathway recommendations (elements/processes) are studied, implemented, audited, evaluated, and optimized by the maternity care teams, this will create an opportunity for the focused and optimized areas of care research with further enhanced care and recommendation.
