Disparities in health and nutrition between semi-urban and rural mothers and birth outcomes of their newborns in Bukavu, DR Congo: a baseline assessment. Prim Health Care Res Dev 2023; 24:e61. [PMID: 37870120 PMCID: PMC10594532 DOI: 10.1017/s1463423623000518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 03/29/2023] [Accepted: 08/28/2023] [Indexed: 10/24/2023] Open
Abstract
AIM This research aimed to evaluate health and nutritional practices of mothers during pregnancy and birth outcomes of their newborns in Bukavu, Democratic Republic of the Congo (DRC), comparing semi-urban and rural areas. BACKGROUND Health and nutrition during pregnancy are crucial for adequate development of the fetus. Health care plays an important role but is often poor in rural areas of developing countries. METHODS A baseline survey of a nutritional follow-up study was conducted in two semi-urban and one rural hospital in the vicinity of Bukavu, DRC. In total, 471 mother-child pairs were recruited after delivery. Data collection included socio-demographic parameters, nutrition and health measures during pregnancy, and anthropometric parameters. Semi-urban and rural study locations were compared and predictors of birth weight evaluated. FINDINGS Semi-urban and rural mothers differed significantly in nutrition and health practices during pregnancy, as well as birth outcomes. In the rural area, there was a higher rate of newborns with low birth weight (10.7%) and lower rates of antimalarial medication (80.8%), deworming (24.6%), consumption of nutritional supplements (81.5%), and being informed about nutrition by medical staff (32.8%) during pregnancy as well as practicing family planning (3.1%) than in the semi-urban areas (2.7%, 88.6%, 88.3%; 89.3%, 46.5%, and 17.1%, respectively). Birth weight was positively predicted by increasing maternal MUAC, age, and gestational age and negatively by rural location, being primipara, being a farmer, and female newborn sex. CONCLUSION The findings highlight the importance of strengthening antenatal care activities especially in rural areas in order to ameliorate both maternal and infantile health and ensure appropriate development.

Abstract
The perioperative period poses a risk for anemia due to the high prevalence of pre-existing anemia secondary to underlying pathologies in patients who are candidates for surgery, and as a result of the increased blood loss caused by surgery. Pre-operative anemia is an independent risk factor associated with higher risk of blood transfusion and negative surgery outcomes. Anemia and iron deficiency (ID), the main causes of pre-operative anemia, can be easily diagnosed with blood testing and are readily treated before elective surgery. However, pre-surgical screening and treatment of anemia and ID are frequently overlooked. These topics were presented and discussed at the symposium entitled "Recovery after Surgery: Don't Forget to Check Iron Status Before", held at the 11th Annual Meeting of the European Urogynaecological Association (EUGA) in October 2018 in Milan. The objectives of the symposium were to stress the high prevalence and the consequences of pre-operative anemia, illustrated with three clinical cases of women undergoing surgery, and to choose the best option for iron supplementation. In conclusion, it is essential to take time to diagnose and treat iron deficiency anemia (IDA) before surgery. The first-line treatment is oral iron when surgery can be delayed and when there is no intolerance to oral treatment or inefficient uptake, as in the case of iron sequestration or absorption disorders. Among iron preparations, ferrous sulfate in a polymeric complex (FSPC) was found to be one of the treatments of choice to improve hemoglobin iron stores and quality of life in IDA patients.

Abstract
We explored the role of lipid accumulation products and visceral adiposity on the association between red meat consumption (RMC) and markers of insulin resistance (IR) and inflammation in USA adults. Data on RMC and health outcome measurements were extracted from the 2005-2010 US National Health and Nutrition Examination Surveys. Overall 16 621 participants were included in the analysis (mean age = 47·1 years, 48·3 % men). ANCOVA and 'conceptus causal mediation' models were applied while accounting for survey design. In adjusted models, a lower RMC was significantly associated with a cardio-protective profile of IR and inflammation. BMI had significant mediation effects on the association between RMC and C-reactive protein (CRP), apo B, fasting blood glucose (FBG), insulin, homoeostatic model assessment of IR and β-cell function, glycated Hb (HbA1c), TAG:HDL ratio and TAG glucose (TyG) index (all Ps < 0·05). Both waist circumference and anthropometrically predicted visceral adipose tissue mediated the association between RMC and CRP, FBG, HbA1c, TAG:HDL ratio and TyG index (all Ps < 0·05). Our findings suggest that adiposity, particularly the accumulation of abdominal fat, accounts for a significant proportion of the associations between red meat consumption, IR and inflammation.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the clinical efficacy of a single-dose intravenous infusion of iron isomaltoside compared with current treatment practice with oral iron measured by physical fatigue in women after postpartum haemorrhage. MATERIALS AND METHODS Single-centre, open-label, randomized controlled trial. Participants received intravenous iron (n = 97) or oral iron (n = 99), and completed the Multidimensional Fatigue Inventory and Edinburgh Postnatal Depression Scale, and haematological and iron parameters were measured. Primary outcome was the aggregated change in physical fatigue score from baseline to 12 weeks postpartum. RESULTS The difference in physical fatigue score was -0·97 (95% CI: -1·65; -0·28, P = 0·006) in favour of intravenous iron, but did not meet the predefined difference of 1·8. Across visits, we found statistically significant differences in fatigue and depression scores, as well as in haematological and iron parameters, all in favour of intravenous iron. There were no serious adverse reactions. CONCLUSION A single dose of intravenous iron was associated with a statistically significant reduction in aggregated physical fatigue within 12 weeks after postpartum haemorrhage compared to standard medical care with oral iron below the prespecified criteria of clinical superiority. As patient-reported outcomes improved significantly and intravenous iron resulted in a fast hematopoietic response without serious adverse reactions, intravenous iron may be a useful alternative after postpartum haemorrhage if oral iron is not absorbed or tolerated.

Abstract
INTRODUCTION Anemia in pregnancy affects 25% of all pregnancies in Europe with iron deficiency affecting even more. Despite supplementation, iron deficiency persists. This review will assess the effect on serum ferritin (iron stores) and hemoglobin (oxygen-carrying capacity) following iron supplementation in pregnant women with anemic and non-anemic iron deficiency. MATERIAL AND METHODS A systemic search of electronic databases and trial registers was conducted from inception to January 2014. Randomized controlled trials of iron supplementation that measured serum ferritin and hemoglobin levels before and after supplementation were selected. Two independent reviewers selected studies, extracted data and assessed quality. Descriptive analyses were carried out. RESULTS The review included 23 randomized controlled trials (3525 women). In iron deficiency anemia, more studies described statistically significant increases in serum ferritin levels than in hemoglobin levels following intravenous iron supplementation. In non-anemic iron deficiency there were more statistically significant increases in serum ferritin levels than in hemoglobin levels following oral supplementation. There were no studies reporting maternal quality of life outcomes. CONCLUSIONS Serum ferritin appears to change more than hemoglobin following iron supplementation. The clinical effects of this need further investigation.

Abstract
Background Low serum ferritin levels signify low iron stores and this could predispose to iron deficiency anemia. Objective To determine the rate and predictors of low serum ferritin levels during the puerperium in Enugu, Southeast Nigeria. Study design A hospital-based prospective longitudinal study involving parturient women who delivered singleton fetuses at term. Venous blood samples were collected to determine the serum ferritin concentration at 48 hours and 6 weeks postpartum. Data analysis involved descriptive and inferential statistics at 95% confidence interval (CI) using Statistical Package for Social Sciences (SPSS) computer software version 20.0. Results Two-hundred and two women who carried singleton pregnancies to term were studied. The mean serum ferritin levels at 48 hours and 6 weeks were 27.82±18.41 µg/L and 36.12±21.53 µg/L, respectively. Forty-eight hours postdelivery, 29.2% had low ferritin levels and this decreased to 12.4% at 6 weeks postpartum. There was a significant positive correlation between the serum ferritin level at 48 hours postdelivery and the serum ferritin level at 6 weeks postpartum (r=0.89, P<0.001). Predictors of the low ferritin level at 6 weeks included age <20 years (odds ratio [OR] =0.70, 95% CI =0.53, 0.93), multiparity (OR =63.7, 95% CI =3.18, 127.5), anemia at 48 hours postpartum (OR =61.7, 95% CI =13.27, 116.6), a low ferritin level at 48 hours (OR =78.1, 95% CI =8.8, 108.3), and intake of antenatal hematinics for <3 months (OR =0.04, 95% CI =0.01, 0.20). Conclusion There was a significant occurrence of low ferritin levels during the puerperium in the study centers, and this was associated mainly with pregnancy and delivery factors. Efforts to improve the iron stores in parturient women could benefit from early booking and compliance with antenatal hematinics and optimizing hemoglobin and iron levels before delivery.

Abstract
Background. The potential benefits of administering a dose of intravenous iron in patients with moderate postpartum anaemia rather than oral iron alone remains unproven. Aims. To determine whether a single injection of intravenous iron followed by a 6-week course of oral iron is as effective over 6 months in restoring normal haemoglobin levels and replenishing iron stores in women with moderate postpartum anaemia as a course of oral iron alone in women with mild postpartum anaemia. Materials and Methods. Retrospective two-arm cohort study in women with mild postpartum anaemia (haemoglobin 9.6–10.5 g/dL) prescribed iron daily for 6 weeks (N = 150) and women with moderate postpartum anaemia (haemoglobin 8.5–9.5 g/dL), given a single 500 mg injection of intravenous iron followed by iron daily for 6 weeks (N = 75). Haemoglobin and ferritin were measured 6 months postpartum. Results. Haemoglobin returned to similar mean levels in both groups. Ferritin levels were statistically significantly higher in the intravenous + oral group (57.7 ± 49.3 μg/L versus 32.9 ± 20.1 μg/L). Conclusions. Despite lower baseline haemoglobin, intravenous iron carboxymaltose was superior to oral iron alone in replenishing iron stores in moderate postpartum anaemia and may prove similarly beneficial in mild postpartum anaemia.

Abstract
OBJECTIVE A systematic review was conducted to analyze the tolerability of several oral iron supplements based on data obtained in available publications and to report the incidence of adverse effects (AEs) for each supplement both overall and gastrointestinal. METHODS Electronic databases - Medline, the Cochrane Library, and Embase were searched for studies published up to January 2009. Clinical or observational studies reporting data on the tolerability of oral iron supplements were included. Results were described statistically and a quasi-binomial logistic regression model was developed to evaluate and compare the tolerability of the supplements studied. RESULTS For this review 111 studies were included, with data on 10,695 patients. Ferrous sulfate with mucoproteose had the lowest incidence of AEs (4.1% for overall AEs, 3.7% for gastrointestinal AEs [GAEs]) and was used as the reference supplement in the regression model. Incidence rates of overall AEs for the other supplements were 7.3% for iron protein succinylate [GAEs: 7%; OR for AE compared to the reference supplement, 1.96], 23.5% for ferrous glycine sulfate [GAEs: 18.5%; OR: 5.90], 30.9% for ferrous gluconate [GAEs: 29.9%; OR: 11.06], 32.3% for ferrous sulfate without mucoproteose [GAEs: 30.2%; OR: 11.21], and 47.0% for ferrous fumarate [GAEs: 43.4%; OR: 19.87]. The differences in incidence of AEs between extended-release ferrous sulfate with mucoproteose and all other supplements except iron protein succinylate were statistically significant at p < 0.001. These findings are subject to some limitations as the designs and methodologies of the studies included show heterogeneity among them that has partially been counteracted by the large sample size provided by the substantial number of trials, which is considered a strength in tolerability studies. CONCLUSION Extended-release ferrous sulfate with mucoproteose appears to be the best tolerated of the different oral iron supplements evaluated.

Abstract
BACKGROUND The true benefit of iron supplementation for nonanemic menstruating women with fatigue is unknown. We studied the effect of oral iron therapy on fatigue and quality of life, as well as on hemoglobin, ferritin and soluble transferrin receptor levels, in nonanemic iron-deficient women with unexplained fatigue. METHODS We performed a multicentre, parallel, randomized controlled, closed-label, observer-blinded trial. We recruited from the practices of 44 primary care physicians in France from March to July 2006. We randomly assigned 198 women aged 18-53 years who complained of fatigue and who had a ferritin level of less than 50 ug/L and hemoglobin greater than 12.0 g/dL to receive either oral ferrous sulfate (80 mg of elemental iron daily; n=102) or placebo (n=96) for 12 weeks. The primary outcome was fatigue as measured on the Current and Past Psychological Scale. Biological markers were measured at 6 and 12 weeks. RESULTS The mean score on the Current and Past Psychological Scale for fatigue decreased by 47.7% in the iron group and by 28.8% in the placebo group (difference -18.9%, 95% CI -34.5 to -3.2; p=0.02), but there were no significant effects on quality of life (p=0.2), depression (p=0.97) or anxiety (p=0.5). Compared with placebo, iron supplementation increased hemoglobin (0.32 g/dL; p=0.002) and ferritin (11.4 μg/L; p<0.001) and decreased soluble transferrin receptor (-0.54 mg/L; p<0.001) at 12 weeks. INTERPRETATION Iron supplementation should be considered for women with unexplained fatigue who have ferritin levels below 50 μg/L. We suggest assessing the efficiency using blood markers after six weeks of treatment. Trial registration no. EudraCT 2006-000478-56.

Abstract
Iron deficiency in the postpartum period is common and associated with impaired quality of life. Interpretation of ordinary laboratory parameters is considered to be simple in postpartum women, as normalization of pregnancy induced physiological changes is assumed to take place in the early postpartum period. We have studied changes in erythrocyte and iron parameters during the first 11 postpartum months. Erythrocyte parameters and iron markers, serum ferritin, and soluble transferrin receptor (sTfR), and an inflammation marker, neopterin, were investigated in healthy mothers 6 weeks (n = 104), 4 months (n = 100), and 11 months (n = 43) after giving birth to a term infant. Healthy nonpregnant and nonlactating women (n = 61) were included as controls. The hemoglobin level increased throughout the first 11 postpartum months and was significantly higher from 4 months on, compared to control women. At all time points, the mothers had significantly lower mean corpuscular volume (MCV) and higher erythrocyte count and percentage of hypochromic erythrocytes. sTfR levels were significantly higher over the whole serum ferritin distribution during the first 4 postpartum months compared to the controls, indicative of an increased cell production. At 6 weeks, postpartum mothers had higher neopterin levels and this was associated with markers of a low iron status, not including sTfR. Substantial changes in erythrocyte and iron parameters were observed in the postpartum period, consistent with an increased, but iron restricted erythropoiesis. The increased erythropoietic activity was reflected in higher sTfR concentrations. Given the vital role for iron in both mothers and infants, further studies are warranted for establishing proper cut off levels for sTfR as an iron marker in postpartum women.

Abstract
BACKGROUND The objective was to evaluate efficacy and safety of rapid, large-dose intravenous (IV) administration of ferric carboxymaltose compared to oral iron in correcting iron deficiency anemia due to heavy uterine bleeding. STUDY DESIGN AND METHODS In a randomized, controlled trial, 477 women with anemia, iron deficiency, and heavy uterine bleeding were assigned to receive either IV ferric carboxymaltose (<or=1000 mg over 15 min, repeated weekly to achieve a total calculated replacement dose) or 325 mg of ferrous sulfate (65 mg elemental iron) prescribed orally thrice daily for 6 weeks. RESULTS Compared to those assigned to ferrous sulfate, more patients assigned to ferric carboxymaltose responded with a hemoglobin (Hb) increase of 2.0 g/dL or more (82% vs. 62%, 95% confidence interval for treatment difference 12.2-28.3, p < 0.001), more achieved a 3.0 g/dL or more increase (53% vs. 36%, p < 0.001), and more achieved correction (Hb >or= 12 g/dL) of anemia (73% vs. 50%, p < 0.001). Patients treated with ferric carboxymaltose compared to those prescribed ferrous sulfate reported greater gains in vitality and physical function and experienced greater improvement in symptoms of fatigue (p < 0.05). There were no serious adverse drug events. CONCLUSIONS In patients with iron deficiency anemia due to heavy uterine bleeding, rapid IV administration of large doses of a new iron agent, ferric carboxymaltose, is more effective than oral iron therapy in correcting anemia, replenishing iron stores, and improving quality of life.

Abstract
Although red meat consumption has been related to the prevalence of diabetes, few data are available showing the relation among red meat intake, inflammation, and metabolic syndrome. We aimed to identify the association between red meat intake, metabolic syndrome, and circulating concentrations of C-reactive protein (CRP) as a surrogate measure of inflammation. In a cross-sectional study of 482 Tehrani female teachers aged 40-60 y, we used a FFQ to assess red meat intake. Anthropometric measures, blood pressure, fasting plasma glucose, lipid profiles, and plasma CRP concentrations were evaluated according to standard methods. Metabolic syndrome was defined as recommended by National Cholesterol Education Program Adult Treatment Panel III guidelines. Red meat intake (mean +/- SEM) was 45.9 +/- 3.0 g/d. After statistically controlling for potential confounders, geometric mean plasma CRP concentrations across increasing quintile categories of red meat intake were 1.46, 1.66, 1.73, 1.89 +/- 1.89, and 2.03 mg/L (P-trend < 0.01). In the crude model, individuals in the top quintile of red meat intake had greater odds of having metabolic syndrome compared with those in the bottom quintile [odds ratio (OR): 2.33; 95% CI: 1.24, 4.38, P-trend < 0.01]. This association remained significant even after adjustment for potential confounders (OR, 2.15; CI, 1.18, 4.01; P-trend <0.01). Adjustment for CRP did not affect this association (OR, 2.06; CI, 1.16, 3.98; P-trend <0.01). In conclusion, increased red meat consumption is cross-sectionally associated with greater risk of metabolic syndrome and inflammation. Further prospective investigations will be needed to confirm this finding.

Abstract
OBJECTIVE To estimate efficacy of rapid, large-dose intravenous (IV) administration of ferric carboxymaltose compared with oral iron therapy in anemic postpartum women. METHODS In a randomized, controlled trial, we assigned anemic women (hemoglobin [Hb] less than or equal to 10 g/dL) within 10 days postpartum to receive either IV ferric carboxymaltose (less than or equal to 1,000 mg over 15 minutes, repeated weekly to achieve a total calculated replacement dose) or ferrous sulfate (FeSO(4)) 325 mg orally thrice daily for 6 weeks. RESULTS One hundred seventy-four patients received 350 IV doses of ferric carboxymaltose (mean total dose 1,403.1 mg) in 3, 2, or 1 injection (10.9%, 79.3%, or 9.8% of patients, respectively); 178 received FeSO(4). Patients assigned to IV ferric carboxymaltose compared with those assigned to oral iron achieved a Hb rise greater than or equal to 2.0 g/dL earlier (7.0 compared with 14.0 days, P<.001), were more likely to achieve a Hb rise greater than or equal to 3.0 g/dL at any time (86.3% compared with 60.4%, P<.001), and were more likely to achieve a Hb greater than 12.0 g/dL (90.5% compared with 68.6%, P<.001). A similar proportion of patients achieved a Hb rise greater than or equal to 2.0 g/dL (96.4% compared with 94.1%, IV compared with oral, P=.443). There were no serious adverse drug reactions. CONCLUSION Large-dose IV ferric carboxymaltose administration is a new iron agent that is effective for the treatment of postpartum anemia. When compared with oral ferrous sulfate, IV ferric carboxymaltose is better tolerated, prompts a more rapid Hb response, and corrects anemia more reliably.

Abstract
Red meat intake has been associated with increased risk of coronary heart disease and type 2 diabetes, but it remains uncertain whether these associations are causally related to unprocessed lean red meat. It has been proposed that iron derived from red meat may increase iron stores and initiate oxidative damage and inflammation. We aimed to determine whether an increase in unprocessed lean red meat intake, partially replacing carbohydrate-rich foods, adversely influences markers of oxidative stress and inflammation. Sixty participants completed an 8-wk parallel-designed study. They were randomized to maintain their usual diet (control) or to partially replace energy from carbohydrate-rich foods with approximately 200 g/d of lean red meat (red meat) in isoenergetic diets. Markers of oxidative stress and inflammation were measured at baseline and at the end of intervention. Results are presented as the mean between-group difference in change and [95% CI]. Red meat, relative to control, resulted in: higher protein [5.3 (3.7, 6.9) % of energy], lower carbohydrate [-5.3 (-7.9, -2.7)% of energy], and higher iron [3.2 (1.1, 5.4) mg/d] intakes; lower urinary F2-isoprostane excretion [-137 (-264, -9) pmol/mmol creatinine], lower leukocyte [-0.51 (-0.99, -0.02)x10(9)/L] counts, and a trend for lower serum C-reactive protein concentrations [-1.6 (-3.3, 0.0) mg/L, P=0.06]; and no differences in concentrations of plasma F2-isoprostanes [-12 (-122, 100) pmol/L], serum gamma-glytamyltransferase [-0.8 (-3.2, 1.5) U/L], serum amyloid A protein [-1.4 (-3.4, 0.5) mg/L], and plasma fibrinogen concentrations [-0.08 (-0.40. 0.24) g/L]. Our results suggest that partial replacement of dietary carbohydrate with protein from lean red meat does not elevate oxidative stress or inflammation.

Abstract
Although iron therapy is essential to optimize use of erythropoiesis-stimulating agents (ESA), randomized, controlled trials have heretofore been unavailable to evaluate reliably the efficacy of intravenous iron as an adjuvant to ESA treatment in peritoneal dialysis (PD) patients. In a multicenter trial, patients who had anemia, PD-dependent chronic kidney disease, stable ESA therapy, and a broad range of iron status (ferritin < or = 500 ng/ml, transferrin saturation < or = 25%) were randomly assigned to receive either 1 g of iron sucrose intravenously in three divided doses (300 mg over 1.5 h on days 1 and 15, 400 mg over 2.5 h on day 29) or no supplemental iron. No serious adverse drug events occurred after intravenous iron administration. The primary end point, peak hemoglobin increase, was higher (1.3 +/- 1.1 versus 0.7 +/- 1.1, mean +/- SD; P = 0.0028), and anemia intervention (transfusion, increase in ESA dose, or intravenous iron therapy not called for in protocol) occurred later (P = 0.0137) and less often in intravenous iron-treated patients compared with untreated control subjects (one of 66 [1.3%] versus five of 30 [16.7%]). Among patients who did not require intervention, iron-treated patients showed a calculated net ESA dose decrease compared with untreated control subjects. Baseline iron status did not predict responsiveness to intravenous iron therapy. Intravenous iron sucrose is an effective adjunct to ESA therapy in anemic patients with PD-dependent chronic kidney disease and is administered safely as 300 mg over 1.5 h or 400 mg over 2.5 h. Evidence of iron deficiency at baseline is not required to demonstrate intravenous iron efficacy.
