RESUMO

INTRODUCTION: Anaemia in the elderly is often difficult to treat with iron supplementation alone as prevalence of anaemia of chronic disease (ACD) alone or mixed with iron-deficiency anaemia (IDA) is high in this age group. Hepcidin remains high in ACD, preventing utilisation of iron for heme synthesis. Vitamin D3 has shown hepcidin suppression activity in both in vitro and in vivo studies. As there is no study assessing the effect of iron-folic acid (IFA) with vitamin D3 on haemoglobin levels in the elderly in India, we want to conduct this study to estimate the impact of supplementation of a therapeutic package of IFA and vitamin D3 on haemoglobin levels in the elderly with mild-to-moderate anaemia in comparison with IFA only. The study will also assess the impact of the proposed intervention on ferritin, hepcidin, 25-hydroxyvitamin D, C reactive protein (CRP) and parathyroid hormone (PTH) levels. METHODS AND ANALYSIS: This study is a community-based, double-blind, placebo-controlled, randomised trial. The study will be done in the Kalyani municipality area. Individuals aged ≥60 years with mild-to-moderate anaemia and normal vitamin D3 levels will be randomised into the intervention (IFA and vitamin D3 supplementation) group or the control group (IFA and olive oil as placebo). All medications will be self-administered. Follow-up will be done on a weekly basis for 12 weeks. The calculated sample size is 150 in each arm. Block randomisation will be done. The primary outcome is change in haemoglobin levels from baseline to 12 weeks. Secondary outcome is change in serum ferritin, 25-hydroxyvitamin D, hepcidin, CRP and PTH levels from baseline to 12 weeks. ETHICS AND DISSEMINATION: Ethical approval from the Institutional Ethics Committee of All India Institute of Medical Sciences Kalyani has been obtained (IEC/AIIMS/Kalyani/Meeting/2022/03). Written informed consent will be obtained from each study participant. The trial results will be reported through publication in a reputable journal and disseminated through health talks within the communities. TRIAL REGISTRATION NUMBER: CTRI/2022/05/042775. PROTOCOL VERSION: Version 1.0.

RESUMO

BACKGROUND: The World Health Organization recommends universal iron supplementation for children aged 6-23 months in countries where anaemia is seen in over 40% of the population. Conventional ferrous salts have low efficacy due to low oral absorption in children with inflammation. Haem iron is more bioavailable, and its absorption may not be decreased by inflammation. This study aims to compare daily supplementation with haem iron versus ferrous sulphate on haemoglobin concentration and serum ferritin concentration after 12 weeks of supplementation. METHODS: This will be a two-arm, randomised controlled trial. Gambian children aged 6-12 months with anaemia will be recruited within a predefined geographical area and recruited by trained field workers. Eligible participants will be individually randomised using a 1:1 ratio within permuted blocks to daily supplementation for 12 weeks with either 10.0 mg of elemental iron as haem or ferrous sulphate. Safety outcomes such as diarrhoea and infection-related adverse events will be assessed daily by the clinical team (see Bah et al. Additional file 4_Adverse event eCRF). Linear regression will be used to analyse continuous outcomes, with log transformation to normalise residuals as needed. Binary outcomes will be analysed by binomial regression or logistic regression, Primary analysis will be by modified intention-to-treat (i.e., those randomised and who ingested at least one supplement dose of iron), with multiple imputations to replace missing data. Effect estimates will be adjusted for baseline covariates (C-reactive protein, alpha-1-acid glycoprotein, haemoglobin, ferritin, soluble transferrin receptor). DISCUSSION: This study will determine if therapeutic supplementation with haem iron is more efficacious than with conventional ferrous sulphate in enhancing haemoglobin and ferritin concentrations in anaemic children aged 6-12 months. TRIAL REGISTRATION: Pan African Clinical Trial Registry PACTR202210523178727.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The traditional Chinese herb Panax notoginseng (PN) tonifies blood, and its main active ingredient is saponin. PN is processed by different methods, resulting in different compositions and effects. AIM OF THE STUDY: To investigate changes in the microstructure and composition of fresh PN processed by different techniques and the anti-anemia effects on tumor-bearing BALB/c mice after chemotherapy with cyclophosphamide (CTX). MATERIALS AND METHODS: Fresh PN was processed by hot-air drying (raw PN, RPN), steamed at 120 °C for 5 h (steamed PN, SPN), or fried at 130 °C, 160 °C, or 200 °C for 8 min (fried PN, FPN1, FPN2, or FPN3, respectively); then, the microstructures were compared with 3D optical microscopy, quasi-targeted metabolites were detected by liquid chromatography tandem mass spectrometry (LC‒MS/MS), and saponins were detected by high-performance liquid chromatography (HPLC). An anemic mouse model was established by subcutaneous H22 cell injection and treatment with CTX. The antianemia effects of PN after processing via three methods were investigated by measuring peripheral blood parameters, performing HE staining and measuring cell proliferation via immunofluorescence. RESULTS: 3D optical profiling revealed that the surface roughness of the SPN and FPN was greater than that of the other materials. Quasi-targeted metabolomics revealed that SPN and FPN had more differentially abundant metabolites whose abundance increased, while SPN had greater amounts of terpenoids and flavones. Analysis of the composition and content of the targeted saponins revealed that the contents of rare saponins (ginsenoside Rh1, 20(S)-Rg3, 20(R)-Rg3, Rh4, Rk3, Rg5) were greater in the SPN. In animal experiments, the RBC, WBC, HGB and HCT levels in peripheral blood were increased by SPN and FPN. HE staining and immunofluorescence showed that H-SPN and M-FPN promoted bone marrow and spleen cell proliferation. CONCLUSION: The microstructure and components of fresh PN differed after processing via different methods. SPN and FPN ameliorated CTX-induced anemia in mice, but the effects of PN processed by these two methods did not differ.

RESUMO

BACKGROUND: Anemia is associated with adverse outcomes and prolonged hospitalizations in critically ill patients. Regarding the recent adoption of restrictive transfusion protocols in intensive care unit (ICU) management, anemia remains highly prevalent even after ICU discharge. This study aimed to investigate the prevalence of anemia following ICU discharge and factors affecting recovery from anemia. METHODS: In this retrospective cohort study involving 3969 adult ICU survivors, we assessed anemia severity using the National Cancer Institute criteria at six time points: ICU admission, ICU discharge, hospital discharge, and at 3-, 6-, and 12-month post-hospital discharge. In addition, baseline characteristics, including age, sex, comorbidities, and recent iron supplementation or erythropoietin administration, were evaluated. RESULTS: Our findings revealed an in-hospital mortality rate of 28.6%. The median hospital and ICU stays were 20 and 5 days, respectively, with common comorbidities including hypertension, and diabetes mellitus (DM). Among the patients, the hemoglobin levels of 3967 patients were confirmed at the time of discharge from the ICU, representing 99.95% of the total. The prevalence of anemia persisted post- ICU discharge; less than 30% of patients recovered, whereas 13.6% of them experienced worsening of anemia post-ICU discharge. Factors contributing to anemia severity were female sex, DM, chronic renal failure, malignant solid tumors, and administration of iron supplements. CONCLUSIONS: This study highlighted the need for targeted interventions to manage anemia post-ICU discharge and suggested potential factors that influence recovery from anemia.

RESUMO

A 2-year-old boy presented to Kapsowar Mission Hospital in Kenya with a history of general tiredness associated with mild, unilateral epistaxis and one episode of hematemesis. On admission, he had a hemoglobin value of 3.5 g/dL, with a white cell count of 20.6 × 109/L. The child was examined by the physician on call, with no source of bleeding found. Later that day, after a local physician noted that the presentation could be due to an unrecognized leech infestation, a deep examination of the oropharynx was performed with a laryngoscope and revealed a leech attached deep in the oropharynx. The anesthetist visualized the leech with a laryngoscope and removed it with Magill forceps. After the procedure and blood transfusion, the child's hemoglobin level improved to 10.4 g/dL, and on the following day, the child was much improved in energy and was playing outside. He was discharged home on iron supplements and made a full recovery.

RESUMO

Maternal anaemia is a major public health problem. Developing maternal anaemia prevention and control policies is an important prerequisite for carrying out evidence-based interventions. This article reviews maternal anaemia prevention and control policies in China, identifies gaps, and provides references for other countries. We examined policies concerning maternal nutrition and other related literature in China, identified through key databases and government websites, and conducted a narrative review of the relevant documentations guided by the Smith Policy-Implementing-Process framework. A total of 65 articles and documents were identified for analysis. We found that Chinese government has committed to reducing maternal anaemia at the policy level, with established objectives and a clear time frame. However, most of policies were not accompanied by operational guidelines, standardized interventions, and vigorous monitoring and evaluation mechanisms, and 85% of the policies don't have quantifiable objectives on anaemia. Maternal anaemia prevention and control services offered in clinical settings were primarily nutrition education and anaemia screening. Population-based interventions such as iron fortification have yet to be scaled up. Furthermore, medical insurance schemes in some regions do not cover anaemia prevention and treatment, and in other regions that offer coverage, the reimbursement rate is low. The number and capacity of health professionals is also limited. Policy changes should focus on the integration of evidence-based interventions into routine antenatal care services and public health service packages, standardization of dosages and provision of iron supplementation, streamline of reimbursement for outpatient expenses, and capacity building of health professionals.

RESUMO

BACKGROUND: The immediate postpartum period is a very crucial phase for both the life of the mother and her newborn baby. Anemia is the most indirect leading cause of maternal mortality. However, anemia in the immediate postpartum period is a neglected public health problem in Ethiopia. Therefore, this systematic review and meta-analysis aimed to estimate the pooled magnitude of immediate postpartum anemia and the pooled effect size of associated factors in Ethiopia. METHODS: Searching of published studies done through PubMed, Medline, Cochrane, African index Medicus, List of Reference Index, Hinari, and Google Scholar. This systematic review and meta-analysis follow the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) godliness. The quality of studies was assessed by using a Newcastle- Ottawa Scale (NOS) assessment tool. Analysis was performed using a random effect model by using STATA 17 version software. Egger's weighted regression and I2 test were used to evaluate publication bias and heterogeneity respectively. RESULTS: In this systematic review and meta-analysis, a total of 6 studies were included. The pooled magnitude of immediate postpartum anemia in Ethiopia was 27% (95%CI: 22, 32). Instrumental mode of delivery (OR = 3.14, 95%CI: 2.03, 4.24), mid-upper arm circumference (MUAC) measurement < 23 cm (OR = 3.19, 95%CI: 1.35, 5.03), Antepartum Hemorrhage (OR = 4.75, 95%CI: 2.46, 7.03), postpartum hemorrhage (OR = 4.67, 95%CI: 2.80, 6.55), and no iron/foliate supplementation (OR = 2.72, 95%CI: 1.85, 3.60) were the identified factors associated with developing anemia in the immediate postpartum period. CONCLUSION: The overall pooled magnitude of anemia in the immediate postpartum period among Ethiopian women was still a moderate public health problem. Instrumental mode of delivery, mid upper arm circumference (MUAC) measurement < 23 cm, antepartum hemorrhage, postpartum hemorrhage, and no iron/foliate supplementation were the identified factors associated with higher odds of developing anemia among immediate postpartum women in Ethiopia. Therefore, midwives, and doctors, shall focus on prevention of maternal hemorrhage, nutritional advice and counseling including iron /foliate supplementation, and avoid unnecessary instrumental delivery to prevent and reduce anemia related maternal mortality and morbidity in Ethiopia.

RESUMO

BACKGROUND: Anemia may be associated with poor clinical outcomes among people living with human immunodeficiency virus (HIV) (PLHIV) despite highly active antiretroviral therapy (HAART). There are concerns that iron supplementation may be unsafe to prevent and treat anemia among PLHIV. OBJECTIVE: The objective of the study was to evaluate the associations of anemia and iron supplementation with mortality and viral load among PLHIV in Tanzania. METHODS: We analyzed data from a cohort of 70,442 nonpregnant adult PLHIV in Tanzania conducted between 2015 and 2019. Regression models evaluated the relationships between anemia severity and iron supplement use with mortality and unsuppressed HIV-1 viral load among all participants and stratified by whether participants were initiating or continuing HAART. RESULTS: Anemia was associated with an increased risk of mortality and unsuppressed viral load for participants who initiated or continued HAART. Iron supplement use was associated with reduced mortality risk but also had a greater risk of an unsuppressed viral load among participants continuing HAART. There was no association of iron supplement use with mortality, and unsuppressed viral load among PLHIV that were initiating HAART. There was a stronger negative association between iron supplement use and the risk of having an unsuppressed viral load among participants with stage III/IV disease compared with stage I/II disease. CONCLUSIONS: Anemia is associated with increased risk of mortality and unsuppressed viral load, but the benefits and safety of iron supplements appear to differ for those initiating compared with continuing ART as well as by HIV disease severity.

RESUMO

BACKGROUND: NCCN Guidelines for Hematopoietic Growth Factors recommend evaluation and treatment of anemia in patients with cancer. However, a paucity of data exists regarding compliance with these recommendations. METHODS: A retrospective cohort study was performed of patients diagnosed with any solid tumor at Vanderbilt University Medical Center from 2008 to 2017. Tumor registry-confirmed cancer cases were identified by ICD-O codes using the Synthetic Derivative database. Anemia was defined as hemoglobin (Hgb) level ≤11 g/dL and graded according to CTCAE version 5.0. Absolute, functional, and possible functional iron deficiency were defined based on NCCN Guidelines. RESULTS: A total of 25,018 patients met inclusion criteria. Median age was 60 years. The most common malignancies were respiratory tract, prostate, and nonprostate urologic (11% each). Among 8,695 patients with Hgb levels available prior to diagnosis, 1,484 (17%) were noted to be anemic proximal to diagnosis. Of the 25,018 patients, 11,019 (44%) were anemic within 6 months of diagnosis. Of these patients, 4,686 (43%) had grade 2 (moderate) anemia and 9,623 (87%) had normocytic anemia. Patients with retroperitoneal/peritoneal cancers had the highest prevalence of anemia (83/110; 75%). A total of 4,125 (37%) underwent any evaluation of their anemia, of whom 1,742 (16%) had iron studies performed and 1,528 (14%) had vitamin B12 or folate studies performed. Fewer than half of patients with anemia received treatment (n=4,318; 39%), including blood transfusion (n=3,528; 32%), oral iron supplementation (n=1,279; 12%), or intravenous iron supplementation (n=97; 1%). Anemia treatment was significantly more frequent as the grade of anemia increased (any treatment among grade 1/mild: 12%; grade 2/moderate: 31%; grade 3/severe: 77%; χ2 [2, n=11,019]=3,020.6; P<.001). Patients with penile and testicular cancers had the highest prevalence of anemia evaluation (n=57; 79%). CONCLUSIONS: Anemia is common in patients with solid tumors; yet, compliance with NCCN Guidelines for evaluation and treatment of anemia remains low. There are opportunities to improve compliance with guidelines across the spectrum of cancer care.

RESUMO

G3P2L1, 28+4 weeks of gestation rhesus (Rh) isoimmunised pregnant women, was referred with trichorionic triamniotic triplet pregnancy with Rh antibody titres of 1:32. Nuchal translucency and anomaly scan were within normal limits with no major malformation for any of the fetuses. Obstetric colour Doppler with middle cerebral artery peak systolic volume revealed foetal anaemia in all three fetuses having velocities corresponding to around 1.5 times the median. Decision of intrauterine transfusion of blood to all three fetuses was taken. Access to fetuses was challenging and expertise in interventional ultrasound was required for transfusion. The patient tolerated the procedure well and eventually went on to deliver uneventfully at 34 weeks of gestation for worsening pre-eclampsia. After birth, all three triplets received triple-surface intensive phototherapy and intravenous immunoglobulin at a dosage of 1 g/kg. Phototherapy was gradually reduced and discontinued within 72 hours, and the infants were discharged from the neonatal intensive care unit at 96 hours of age.

RESUMO

BACKGROUND: Erlotinib is a first-generation, tyrosine kinase inhibitor of the epidermal growth factor receptor (EGFR-TKI) used for the treatment patients with NSCLC. Erlotinib is considered as a safe and effective treatment option, with generally good tolerance. Diarrhea and rash are the most common side effects, and more rare side effects appear in long-term real-world applications. Severe erlotinib related megaloblastic anemia is rare and remains unreported. This is the first case report of severe megaloblastic anemia in a patient with advanced lung adenocarcinoma with an EGFR L858R mutation treated with erlotinib. In this report, the clinical manifestations, diagnosis and treatment of erlotinib related severe megaloblastic anemia are described, and the possible pathogenesis and related treatment options are discussed. CASE DESCRIPTION: Herein, we present a 57- year-old non-smoking female diagnosed with metastatic lung adenocarcinoma harboring an EGFR L858R mutation, who had received erlotinib as the first-line therapy. After 44 weeks of treatment, the patient developed severe anemia. Anemia was manifested as megaloblastic anemia with elevated mean corpuscular volume and mean corpuscular hemoglobin. The total vitamin B12 level was below the detection limit of 50.00 pg /mL. Bone marrow smear suggested megaloblastic anemia. Her hematologic parameters were markedly recovered following the withdrawal of erlotinib and vitamin B12 supplement. As a result, the patient was diagnosed with erlotinib-associated megaloblastic anemia. CONCLUSIONS: This is the first case of severe megaloblastic anemia reported with erlotinib. Few of these hematologic adverse effects have been observed in studies on erlotinib, this case report highlights this possibility for long-term erlotinib administration. Close clinical and blood monitoring is recommended for patients receiving long-term TKI therapy.

RESUMO

BACKGROUND: Women of reproductive age (WRA) in developing countries are often at risk of micronutrient deficiencies due to inadequate intakes and excessive losses. OBJECTIVE: The purpose of this trial is to assess the effectiveness of United Nations International Multiple Micronutrient Antenatal Preparation-Multiple Micronutrient Supplements (UNIMMAP-MMS) versus iron-folic acid (IFA) among WRA in reducing anemia. METHODS: Three parallel groups of WRA will participate in a community-based, individually randomized, double-blinded, placebo-controlled superiority trial. After consent, the sample of 375 mildly or moderately anemic women based on hemoglobin by Hemocue will be randomly assigned across two interventions and one control arm. Trial participants in intervention arms will receive UNIMMAP-MMS or IFA while those in the control arm will receive placebos twice a week for 17 weeks. The primary outcome will be a change in mean hemoglobin (Hb) concentrations. Outcome assessors and study participants will be blinded to the type of supplements and study arm. DISCUSSION: The World Health Organization (WHO) added UNIMMAP-MMS to its essential medicine lists in 2021 but recommended rigorous study. Several factors in addition to inadequate intakes of iron and folic acid contribute to the high prevalence of anemia among WRA in the Somali region. The findings of this study will provide evidence on the effect of UNIMMAP-MMS and IFA on Hb concentrations and anemia prevalence among anemic WRA. TRIAL REGISTRATION: ClinicalTrials.gov NCT05682261.

RESUMO

The impact of the Global Programme to Eliminate Lymphatic Filariasis (GPELF) (initiated in 2000 in Ghana and ran for 12 years) in mitigating soil-transmitted helminth (STH) infections in LF-endemic areas is unknown. During a 1-year hiatus which ensued between 2011 and 2012, a longitudinal study was conducted to determine GPELF effect on hookworm infections in selected communities involved in the programme since its inception, while measuring the effectiveness of biannual ALB treatments on schoolchildren living in such communities. A total of 399 school children aged 3 to 18 years were randomly selected from four communities in the Kpandai district of northern Ghana. Each presented a single stool sample at baseline, 21 days post-treatment, at the 3rd and 6th months, 21 days post-second intervention (i.e. following sample collection and treatment with ALB in the 6th month), and in the ninth month of the study period. Haemoglobin (hb) levels were also measured at all time points using finger prick blood samples and a URIT digital test kit. Each participant submitting a sample, was treated with a single-dose ALB (400mg) at baseline and in the sixth month. Stool samples were processed by preparing duplicate Kato-Katz slides per sample, and examined by microscopy. The Body Mass Index-for-age z-scores (BAZ) of participants were assessed following the determination of BMIs at each time point by measuring their height and weight with a stadiometer and weighing scale. Overall hookworm prevalences were 25.68% (95% CI = 20.51-31.75) at baseline, 11.18% (95% CI = 7.87-15.41) 21 days post-treatment, 11.78% (95% CI = 8.38-16.11) and 6.95% (95% CI = 4.41-10.43) in the 3rd and 6th months, 0.91% (95% CI = 0.19-2.65) 21 days post-second intervention, and 8.46% (95% CI = 5.62-12.23) in the ninth month. Observed overall faecal egg count reduction rates (ERRs) were 94.21% (95% CI = 81.50%- 100.00%) 21 days after baseline treatment, 97.70% (95% CI = 85.08-100.00) and 96.95% (95% CI = 84.18%- 100.00%) in the 3rd and 6th months, 99.98% (95% CI = 86.42%- 100.00%) 21 days post-second intervention, and 17.18% (95% CI = 14.07%- 20.67%) in the 9th month. Respective cure rates (CRs) were 62.35% (95% CI = 46.71-81.56%), 85.88% (95% CI = 67.32-100.00%), 87.06% (95% CI = 68.36%- 100.00%), 98.82% (95% CI = 78.83%- 100.00%), and 36.36% (95% CI = 9.91%- 93.11%). Additionally, increases in the percent frequency of 'normal hb' (p < 0.01) were observed across the study time points, whilst 'normal BAZ' cases remained high (from 94.87% to 98.87%) throughout the study period. These findings primarily indicate satisfactory effectiveness of ALB which may be maintainable in mass drug administration programmes by the modification of treatment strategies from annual to bi-annual regimes. This could minimize the likelihood of emerging poorly-responding hookworm phenotypes in Ghana. Additionally, a positive impact of bi-annual treatment on participant anaemia status is herein indicated with particular regard to the school children in our cohort.

RESUMO

OBJECTIVE: This study aimed to investigate the effects of weight gain and maternal anemia on postpartum depression. METHODS: This is a prospective, single-center, case-control study. We recorded the demographic characteristics, blood ferritin level, and weight gain during the pregnancy. This study was planned between April 2023 and June 2023 in the Obstetrics and Gynecology Clinic of Ankara Etlik City Hospital. A total of 109 patients were enrolled in the study. Patients were assessed with the Edinburgh Postpartum Depression Scale. Weight gain, nutritional education, educational level, mode of delivery, and pregnancy history were asked in person. Ferritin levels at the onset of labor were determined to detect anemia. Twin births, births due to fetal anomalies or intrauterine stillbirths, patients with systemic infections, and patients diagnosed with a psychiatric disorder in the past 6 months whose records were not accessible were excluded from the study. RESULTS: Pregnancy weight gain and percentage of pregnancy weight gain were higher. Serum ferritin levels and nutritional education during pregnancy were lower in the postpartum depression group (p<0.001). These parameters with statistical significance were identified as risk factors in the regression analysis for postpartum depression (p<0.05). In receiver operating characteristics analysis, >15 kg for weight gain, >28.8 for percentage of weight gain in pregnancy, and <19 ng/dL for serum ferritin level were identified as cutoff values (p<0.001). CONCLUSION: Nutritional education and vitamin supplementation should be recommended to pregnant women during routine examinations.

RESUMO

BACKGROUND: The management of chemotherapy induced anemia (CIA) remains challenging. The potential risk and benefits in providing patient-centered care need to be balanced; the disease is multifactorial; and the major treatments including red blood cell (RBC) transfusions, erythropoiesis-stimulating agents (ESAs) and intravenous injection (i.v.)iron supplementation have a unique set of strengths and limitations. Also, most previous survey based on the patient data could not reveal the process of evaluation and decision-making for CIA treatment from a physician's perspective. As the comparison of China Society of Clinical Oncology (CSCO), National Comprehensive Cancer Network (NCCN) and European Society of Medical Oncology (ESMO) guidelines, the standard of CIA treatment in China will vary from United States and Europe, for example, the initial hemoglobin (Hb) for RBC transfusions. In order to understand the diagnosis, treatment, and unmet medical needs of CIA patients, the China Medical Education Association (CMEA), in conjunction with Cancer Hope Medium, initiated the first national survey of Chinese physicians regarding the diagnosis and treatment of CIA. METHODS: The CMEA sent an online, 12-item questionnaire (via wjx.cn) to physicians across China from September 1, 2022 to October 22, 2022. Two hundred and sixty-five samples were calculated usingsurveyplanet.com. The questionnaire evaluated the impact of anemia on chemotherapy interruption, initial treatment, the target Hb level of CIA in, and the current status of ESAs prescription in clinical practice. Respondents were asked to score their reasons for not using ESAs (including safety issues, drug access in practice or adherence) and the risk options of the current treatment including ESAs, RBC transfusion, and i.v.iron. RESULTS: A total of 331 questionnaires among 5,000 web visits were gathered, covering 247 hospitals in 29 provinces across China, of which 130 (53%) were tier IIIA hospitals, 50 (20%) were tier III B hospitals, 59 (24%) were tier IIA hospitals, and 8 (3%) were tier II B hospitals. The frequency of chemotherapy dose delay/reduction due to anemia was 24% [standard deviation (SD) 49%]. Most responding physicians rated an initial Hb level for ESAs treatment to be 80 g/L, with a favorable Hb level for chemotherapy being 100 g/L (60%), which would not limit treatment availability. The majority (67.6%, n=221) of physicians who responded indicated that they had used ESAs for anemia correction, while the others (32.4%, n=106) reported never using them. CONCLUSIONS: This is the first study in conducting a large-scale survey on the diagnosis and treatment of CIA in China from a physicians' perspective. We found that in China, nearly one-quarter of patients undergoing chemotherapy with concurrent anemia may experience interruption of chemotherapy and that the initiation of anemia treatment is not adequately timed. In treating CIA, most physicians prioritize the completion of chemotherapy via Hb level over treating the symptoms of anemia.

RESUMO

BACKGROUND: Immediate postpartum anemia occurs when the amount of red blood cell count is reduced or hemoglobin concentration is below 10 g/dl in the immediate postpartum. It occurs primarily due to inadequate iron intake before and during pregnancy and blood loss during delivery. The aim of this study is to assess the proportion of immediate postpartum anemia and associated factors among mothers who gave birth at Shewarobit health facilities; in Amhara, Ethiopia. METHODS: Institutional-based cross-sectional study was conducted from June to September 2022. A systematic random sampling method was employed to select the study participants. The data were collected through interviewer-assisted questions. Data were entered into Epi Data software version 4.6.0.4 and exported to SPSS 21 for analysis, and descriptive statistics were computed. Logistic regression was applied, and P-values less than 0.05 were considered statistically significant. RESULTS: This study was conducted among 307 study participants and, the proportion of immediate postpartum anemia was 41.4% [95% CI: 36.7-46.6]. Having postpartum hemorrhage [AOR = 4.76, 95% CI: 2.44-9.28], not taking iron and folic acid supplementation [AOR = 6.19, 95% CI: 2.69, 14.22], having a prolonged second stage of labor [AOR = 2.52, 95% CI: 1.16-5.44], and mid-upper arm circumference < 23 cm [AOR = 2.02, 95% CI: 1.11-3.68] were factors significantly associated with immediate postpartum anemia. CONCLUSIONS: The proportion of immediate postpartum anemia was public problem in Shewarobit health facilities. Following the progress of labor using a partograph, closely monitoring and immediate intervention of PPH, and prevent undernutrition during antenatal care is recommended.

RESUMO

Iron is an essential trace element for various cellular proteins and for biological processes in all cells. Severe iron deficiency (ID) impairs haem synthesis, reduces erythropoiesis and causes iron deficiency anaemia (IDA). Iron restriction in anaemia of inflammation is mainly due to retention of iron in macrophages. This condition is known as 'functional iron deficiency'. A review of studies performed in Europe shows that the prevalence of ID and IDA in young children varies by region. It is more common in eastern than western European countries. This overview summarises information on the need for iron supplementation in children, and the current understanding of the regulatory mechanisms of iron homeostasis and ironrestricted erythropoiesis. The causes of anaemia during infection and the usefulness of classical and new indicators to distinguish absolute from functional iron deficiency are discussed.

RESUMO

INTRODUCTION: Risk factors for thromboembolic events in patients with dialysis-dependent chronic kidney disease (CKD) receiving roxadustat are unknown. Iron deficiency has been reported as a risk factor for thrombosis in the general population. METHODS: Thromboembolic events with onset before and after week 12 in patients receiving roxadustat were evaluated in this pooled analysis of four global phase 3 trials, PYRENEES, SIERRAS, HIMALAYAS, and ROCKIES. Baseline risk factors for thromboembolic events were investigated by Cox regression analyses. Nested case-control analyses with matched pairs of case-control data explored the relationship between thromboembolic events and last known laboratory parameters before event onset. RESULTS: Of 2354 patients, 1026 thromboembolic events were observed in 568 patients. Baseline risk factors found included hemodialysis (vs peritoneal dialysis), advanced age (≥ 65 years), Black race, high high-sensitivity C-reactive protein, and history of thromboembolism, cardiovascular disease, or diabetes. Univariate case-control analyses revealed that high hemoglobin rate of rise (≥ 0.5 g/dL/week; odds ratio [OR] 2.09; 95% confidence interval [CI] 0.98-4.46) showed a trend towards increased risk of thromboembolic events before week 12, and high rate of hemoglobin decline was associated with events after week 12 (< - 0.5 g/dL/week; OR 3.73; 95% CI 1.68-8.27) as compared to stable hemoglobin levels (≥ - 0.1 to < 0.1 g/dL/week). Multivariate case-control analyses showed that low last known hemoglobin level (< 10 g/dL: adjusted OR 1.91; 95% CI 1.04-3.50; vs ≥ 12 g/dL) and low last known transferrin saturation (TSAT < 10%: adjusted OR 3.78; 95% CI 1.71-8.39; vs ≥ 30%) before event onset were associated with events after week 12. In patients with last known TSAT < 30%, higher roxadustat dose was associated with thromboembolic events; however, no association was observed in those with TSAT ≥ 30%. CONCLUSIONS: Among various risk factors for thromboembolic events, it is reasonable to avoid a rapid increase and decline in hemoglobin levels as well as ensure TSAT ≥ 30%, rather than increasing the roxadustat dose.

Roxadustat is an oral treatment for patients with anemia, or low hemoglobin levels, due to chronic kidney disease. Thromboembolic events are caused by a blood clot blocking blood vessels, and they have occurred in clinical trials of roxadustat. This analysis evaluated risk factors for thromboembolic events in patients receiving roxadustat to treat anemia of chronic kidney disease who are on dialysis. Two different statistical approaches were used to investigate risk factors for thromboembolic events that occurred before and after 12 weeks of roxadustat treatment. We found that rapid improvement of anemia after starting roxadustat treatment may be associated with an increased risk of thromboembolic events occurring in the first 12 weeks of treatment. In contrast, severe anemia or worsening of anemia was associated with an increased risk of thromboembolic events after week 12. Low iron levels in the blood or greater decline of available iron in the blood from baseline were also detected as risk factors for the events after week 12, suggesting that iron supplementation is important in patients who are iron-deficient. Moreover, thromboembolic events were also associated with older age (≥ 65 years), Black race, high levels of inflammation, and having had a previous thromboembolic event or having a history of cardiovascular disease or diabetes. Some risk factors, such as iron status and hemoglobin levels, can be changed after beginning roxadustat treatment and should be monitored and modified, as needed.

RESUMO

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.

RESUMO

In response to the continuing high prevalence of anaemia recorded in the National Family Health Survey-5, the Indian government launched a policy for mandatory iron fortification of the rice provided through public nutrition programmes in India. This was done even though a rigorous evidence analysis had already concluded that rice fortification was not effective in preventing anaemia or iron deficiency at the population level. Fortification also poses a potential risk of iron toxicity over time, but there is no stated time period for the policy's implementation. The risk is particularly high in segments of the population who already have a high habitual iron intake, and who could be exposed to simultaneous fortification in different staples and food commodities along with the ongoing weekly Iron and Folic Acid tablets supplementation programme. Finally, this fortification policy also requires significant additional funding and resources to implement. It is crucial to examine such mandatory health actions, and to weigh the benefits and risks of harm, using the principles of public health ethics.
