RESUMO

Hemoglobin levels are commonly assessed to prevent causing or worsening of anemia in prospective blood donors. We compared head-to-head the accuracy of different technologies for measuring hemoglobin suitable for use in mobile donation units. We included 144 persons donating platelets at the Central Institute for Blood Transfusion and Immunology in Innsbruck, Austria. Hemoglobin levels were measured in venous blood using the portable hemoglobinometer HemoCue Hb-801 and noninvasively using OrSense NBM-200, and compared to values obtained with the Sysmex XN-430, an automated hematology analyzer employing the sodium lauryl sulphate method, which is broadly used as reference method in everyday clinical practice. Mean age of participants was 34.2 years (SD 13.0); 34.0% were female. Hemoglobin values measured with HemoCue were more strongly correlated with the Sysmex XN-430 (r = 0.90 [95% CI: 0.87-0.93]) than measured with OrSense (r = 0.49 [0.35-0.60]). On average, HemoCue overestimated hemoglobin by 0.40 g/dL (0.31-0.48) and OrSense by 0.75 g/dL (95% CI: 0.54-0.96). When using OrSense, we found evidence for higher overestimation at higher hemoglobin levels (proportional bias) specifically in females but not in males (Pdifference = .003). Sensitivity and specificity for classifying donors according to the hemoglobin donation thresholds were 99.2% (95% CI: 95.3%-100.0%) and 43.8% (23.1%-66.8%) for HemoCue vs 95.3% (89.9%-98.0%) and 12.5% (2.2%-37.3%) for OrSense. Areas under the receiver operating characteristic curves were higher using HemoCue vs OrSense both in females (0.933 vs 0.547; P = .044) and males (0.948 vs 0.628; P < .001). HemoCue Hb-801 measures hemoglobin more accurately than OrSense NBM-200 in the setting of mobile blood donation units. Our findings are particularly relevant for females, having in mind that anemia is more prevalent in females than in males.

RESUMO

BACKGROUND: Although maternal hemoglobin levels during pregnancy are commonly associated with perinatal outcomes, their link to childhood neurodevelopment remains uncertain. OBJECTIVE: This study aimed to examine the associations between maternal hemoglobin in early and late pregnancy and the educational attainment of offspring mid-childhood in a high-resource obstetric setting. STUDY DESIGN: Pregnancy data from a prospective birth cohort (Pregnancy Outcome Prediction Study, Cambridge, United Kingdom, 2008-2012, N=3285) were linked to mid-childhood educational outcomes (Department for Education, United Kingdom). Regression models adjusted for maternal, child, and socioeconomic factors were used to determine associations between maternal hemoglobin, pregnancy complications, and offspring educational outcomes (aged 5-7 years). RESULTS: No association was observed between maternal hemoglobin at 12 weeks and the likelihood of either adverse pregnancy outcomes or children meeting expected educational standards between ages 5-7 years. Higher maternal hemoglobin at 28 weeks was associated with an increased risk of small-for-gestational-age infants (adjusted odds ratio, 1.26 [95% confidence interval, 1.11-1.59]; P=.002) and preterm birth (adjusted odds ratio, 1.38 [95% confidence interval, 1.11-1.81]; P=.005). There were no adverse birth outcomes associated with anemia. However, children of mothers who were anemic at 28 weeks had ∼40% increased risk of not attaining expected educational standards at age 5 (adjusted odds ratio, 1.42 [95% confidence interval, 1.03-1.95]; P=.03). There was no association between maternal anemia at 28 weeks and educational performance at ages 6-7. No associations were found between high maternal hemoglobin concentrations (top decile) or change in hemoglobin concentrations between 12 and 28 weeks and childhood educational attainment. CONCLUSION: Maternal anemia at 28 weeks of pregnancy is associated with reduced educational attainment at 5 years old but not at older ages (6-7 years old). A proactive approach to increasing maternal hemoglobin in high-resource settings is unlikely to impact long-term childhood educational attainment.

RESUMO

The prognostic impact of anemia, especially mild anemia, in atrial fibrillation (AF) remains unclear. We examined clinical burdens of mild anemia on the quality of life (QoL) and clinical outcomes of 1,677 AF patients. Patients were divided into a non-anemia (hemoglobin [Hb] ≥13 g/dl for men and Hb ≥12 g/dl for women) and a mild anemia group (10≤ Hb <13 g/dl for men and 10≤ Hb <12 g/dl for women). At baseline, 22.5% of patients (n = 378) had anemia; patients in the mild anemia group had higher CHA2DS2-VASc scores (3.7 vs 2.7; p <0.01) and brain natriuretic peptide levels (253.5 vs 159.6 pg/ml; p <0.01) and were more likely to develop chronic kidney disease (64.2 vs 42.9%; p <0.01) than those in the non-anemia group. During follow-up (mean 1.7 ± 0.4 years), patients with mild anemia had a higher risk of heart failure hospitalization and major bleeding events than those without (12.2 vs 3.8%; p <0.01 and 5.6 vs 2.5%; p <0.01, respectively). Mild anemia was an independent risk factor for heart failure hospitalization (adjusted hazard ratio: 1.67, 95% confidence interval 1.06 to 2.62, p = 0.03) but not for major bleeding (adjusted hazard ratio: 1.44, 95% confidence interval 0.80 to 2.62, p = 0.23). QoL improvement was less likely in the mild anemia group during follow-up, despite the lack of significant differences at baseline. In conclusion, the presence of even mild anemia was associated with increased risks of heart failure hospitalization and poor QoL improvement.

RESUMO

INTRODUCTION: Anemia during pregnancy is a public health problem that leads to different life-threatening complications and poor pregnancy outcomes. So far, the evidence is scarce on pooled prevalence and determinants of anemia during pregnancy in East Africa for integrated intervention. Therefore, this study aimed to assess the prevalence and determinants of anemia among pregnant women in eastern Africa using recent Demographic and Health Surveys. METHOD: Secondary data analysis was conducted using data from recent Demographic and Health Survey datasets from 10 East African countries. A total of 8583 (weighted sample) pregnant women were included in the analysis. The multi-level mixed-effects generalized linear model (Poisson regression with robust error variance) was fitted to identify determinants of anemia. Finally, the adjusted prevalence ratio (aPR) with 95% CI and random effects for the multilevel generalized linear mixed-effects model was reported. RESULTS: In this study, the overall prevalence of anemia among pregnant women was 41.82% (95% CI: 40.78, 42.87) with a large difference between specific countries which ranged from 23.36% in Rwanda to 57.10% in Tanzania. In the multi-level analysis, teenage pregnant women (aPR = 1.22;95%CI:1.02, 1.40), unmarried women (aPR = 1.14; 95% CI;1.02,1.28), pregnant women who had unimproved toilet facility (aPR = 1.17;95%CI:1.06,1.27), and those women from countries with high illiteracy level (aPR = 1.12;95%CI; 1.07,1.18) had a higher prevalence of anemia during pregnancy. CONCLUSION: Anemia is still a public health problem in East Africa. Therefore, enabling the households to have improved toilet facilities by strengthening the existing health extension program, reducing teenage pregnancy, and improving the community literacy level is vital to reduce the prevalence of anemia during pregnancy in East Africa.

RESUMO

In non-dialysis-dependent chronic kidney disease (NDD-CKD), erythropoiesis-stimulating agents (ESAs) and iron supplementation are essential for anemia management. Ferric carboxymaltose (FCM) is a relatively novel intravenous iron formulation used in different clinical settings, although scarce data exist in NDD-CKD patients. Primary objective of this study was to retrospectively evaluate the efficacy of FCM compared with oral ferrous sulfate for the treatment of iron-deficiency anemia in a cohort of NDD-CKD patients, considering also the treatment costs. This was a monocentric, retrospective observational study reviewing 349 NDD-CKD patients attending an outpatient clinic between June 2013 and December 2016. Patients were treated by either FCM intravenous infusion or oral ferrous sulfate. We collected serum values of hemoglobin, ferritin and transferrin saturation (TSAT) and ESAs doses at 12 and 18 months. The costs related to both treatments were also analysed. 239 patients were treated with FCM intravenous infusion and 110 patients with oral ferrous sulfate. The two groups were not statistically different for age, BMI and eGFR values. At 18 months, hemoglobin, serum ferritin and TSAT values increased significantly from baseline in the FCM group, compared with the ferrous sulfate group. ESAs dose and rate of infusion decreased only in the FCM group. At 18 months, the treatment costs, analysed per week, was higher in the ferrous sulfate group, compared with the FCM group, and this was mostly due to a reduction in ESAs prescription in the FCM group. Routine intravenous FCM treatment in an outpatient clinic of NDD-CKD patients results in better correction of iron-deficiency anemia when compared to ferrous sulfate. In addition to this, treating NDD-CKD patients with FCM leads to a significant reduction of the treatment costs by reducing ESAs use.

RESUMO

The association between anemia and Takotsubo cardiomyopathy (TCM) has not been well studied. To assess the effect of anemia on patients hospitalized with TCM, we identified 4733 patients with a primary diagnosis of TCM from the 2016 to 2018 National Inpatient Sample (NIS) database (the United States) using the International Classification of Diseases, 10th edition, Clinical Modification (ICD-10-CM) code. Of these, 603 (12.7%) patients had a comorbidity of anemia and 4130 did not. After propensity score matching, we compared the in-hospital outcomes between the 2 groups (anemia vs nonanemia, n = 594 vs 1137). Patients with TCM with anemia had significantly higher rates of in-hospital complications, including cardiogenic shock (11.4% vs 4.0%, P < .001), ventricular arrhythmia (6.6% vs 3.6%, P = .008), acute kidney injury (22.7% vs 13.1%, P < .001), acute respiratory failure (22.6% vs 13.1%, P < .001), longer length of hospital stay (5.6 ± 5.8 days vs 3.6 ± 3.6 days, P < .001), and higher total charges (US$79 586 ± 10 2436 vs US$50 711 ± 42 639, P < .001). In conclusion, patients with anemia who were admitted for TCM were associated with a higher incidence of in-hospital complications compared with those without anemia.

RESUMO

BACKGROUND: In 2016, a preoperative clinic was implemented to screen, evaluate, and manage anemia and suboptimal iron stores at a major tertiary care medical center in Western Australia. Few studies compare the costs and reimbursements associated with preoperative anemia and suboptimal iron stores management. The objective of our study was to conduct a net cost analysis associated with the implementation of this clinic. METHODS: We designed a retrospective cohort study involving elective colorectal surgical admissions over a 3-year period. The baseline year selected was the 2015-2016 financial year, with outcomes in the 2016-2017 and 2017-2018 year compared to baseline. The study perspective was the Western Australian Health System. Hospital costs were extracted from the health service clinical costing system, which captures costs at the admission level. The primary outcome was net cost, defined as gross cost minus reimbursement (or funding) received. RESULTS: Our 3-year study included 544 admissions for elective colorectal surgery. After the implementation of the preoperative clinic, 73.4% (n = 257) of admissions were screened for anemia and suboptimal iron stores, and 31.4% (n = 110) received intravenous iron. In our adjusted analysis, when comparing the final year (2017-2018) with baseline (2015-2016), the units of red blood cells transfused per admission decreased 53% (142 vs 303 units per 1000 discharges; P = .006), and mean hospital length of stay decreased 15% (7.7 vs 9.1 days; P = .008). When comparing the final year with baseline, rectal resection admissions were associated with a mean decrease in the net cost of Australian dollar (A$) 7619 (95% confidence interval, 4230-11,008; P < .001) between 2015-2016 and 2017-2018. For small and large bowel procedures, there was a mean decrease of A$6744 (95% confidence interval, 2430-11,057; P = .002). CONCLUSIONS: The implementation of a preoperative anemia and suboptimal iron stores screening and management clinic in elective colorectal surgery was associated with reductions in red cell transfusions, length of stay, and net costs.

RESUMO

According to the World Health Organization, the cutoff hemoglobin (Hb) value for defining anemia is 11 g/dL in preschool-aged children, and Hb measurements should be corrected above an altitude of 1000 meters. This study sought to determine the altitude at which the Hb value increases compared with that at sea level, Hb changes with age and region in Peru, the prevalence of anemia according to three different models used to correct Hb for altitude, and the association of the Hb value with stunting. Two individual-based Peruvian national databases were analyzed. Hb increased from an altitude of 375 meters. Hb concentration was lower at younger ages and higher at older ages. The increase in Hb with increasing altitude was lower in southern Peru. Implementing the different models for Hb measurement correction resulted in a higher and lower prevalence of anemia at altitudes >2500 and <2500 m, respectively, using the CDC adjustment. In children aged 6-23 months, the rate of stunting was lower in those with an Hb level of 10-12 g/dL (including mild anemia). In conclusion, the adjustment of Hb values for altitude should be considered before 1000 m and reference ranges should be adjusted to smaller groups of children instead of the same reference range for children aged 6-59 months.

RESUMO

OBJECTIVE: This study aimed to separately evaluate the prevalence of anemia and iron deficiency in nulliparous and multiparous women. MATERIALS AND METHODS: We retrospectively examined data of women who delivered in our clinic from January 2016 to December 2018. Inclusion criteria were delivery occurring at ≥36 weeks and singleton pregnancy. Pregnant women with severe medical disorders were excluded. We estimated complete blood count (CBC) and serum ferritin (SF) in the first trimester and only CBC in the late second trimester. Data of nulliparas and multiparas were analyzed separately. Statistically significance was set at p < 0.05. RESULTS: Totally, 481 nulliparas and 603 and multiparas were enrolled. Mean hemoglobin values in the first trimester were 12.6 ± 1.0 and 12.4 ± 1.0 g/dl (p < 0.001), while median SF values were 42.7 (12.2, 108.2) and 27.7 (8.0, 72.6) ng/ml (p < 0.001) in nulliparas and multiparas, respectively. Hemoglobin in the late second trimester was 11.2 ± 0.9 and 10.7 ± 1.0 g/dl (p < 0.001) in nulliparas and multiparas, respectively. Low ferritin levels (SF < 12 ng/ml) were more frequently found in multiparas than in nulliparas (111/603 vs. 46/481, p < 0.001, Odds ratio [OR] = 2.13). Anemia in the first trimester (hemoglobin<11.0 g/dl) was found in 3.5% (17/481) and 8.8% (53/603) (p < 0.001; OR, 2.63), while that in late second trimester (hemoglobin<10.5) was observed in 21.0% (101/481) and 36.3% (219/603) (p < 0.001, OR = 2.15) nulliparas and multiparas, respectively. Non-anemic women (hemoglobin level ≥11.0) with low ferritin levels (SF < 12 ng/ml) in the first trimester showed higher rate of anemia development in the second trimester than those with both normal hemoglobin and ferritin levels, irrespective of parity (51.3% [19/37] vs. 16.2% [69/427], p < 0.001 in nulliparas and 76.9% [60/78] vs. 26.5% [125/472], p < 0.001 in multiparas]. CONCLUSION: Anemia and low SF levels occurred more commonly in multiparous than in nulliparas. Further, low SF was a risk factor for anemia development in later pregnancy.

RESUMO

In advanced health systems it is increasingly important to offer effective medical services that have high quality and safety standards. We present an overview of the direct hazards and the indirect hazards associated with blood transfusions. Our aim is to focus on the potential medico-legal impacts of these hazards in the context of clinical risk management, incorporating the accumulating evidence from Patient Blood Management programs. The direct or deterministic hazards of transfusion refer to scenarios where the mechanisms for post transfusion damage are clearly traceable to the blood transfused in a 1:1 cause and effect manner. The indirect hazards can be defined as probabilistic and are associated with transfusion through epidemiological studies. The implementation of Patient Blood Management programs demonstrates that the use of a blood transfusion is not always necessary or unavoidable but can be considered modifiable. Review of the literature confirms that transfusion should not be the default option to manage anemia or blood loss. Instead, accumulating evidence demonstrates that a patient-centred, proactive approach to managing a patient's own blood is the new standard of care. It thus follows, an adverse transfusion event, where the transfusion was avoidable through the application of patient blood management, may constitute a profile for medical professional medical negligence. In an effort to maximise patient safety, transfusion medicine practice culture needs to shift towards a patient blood management approach, with hospitals implementing it as an important tool to minimize the risks of allogeneic blood transfusion.

RESUMO

BACKGROUND: Healthcare spending is expected to grow faster than the economy over the next decade, and the cost of prematurity increases annually. The aim of this study was to investigate the frequency of intervention after routine laboratory testing in preterm infants. METHODS: This was a retrospective study of preterm infants (≤34 weeks) admitted to the NYU Langone Health NICU from June 2013 to December 2014. Data collected included demographics, results of laboratory tests, and resulting interventions. Intervention after a hemogram was defined as a blood transfusion. Intervention after a hepatic panel was defined as initiation or termination of ursodiol or change in dose of vitamin D. Subjects were stratified into 3 groups based on gestation (<28 weeks, 28-31 6/7 weeks, 32-34 weeks). Chi-square analysis was used to compare the frequency of intervention between the groups. RESULTS: A total of 135 subjects were included in the study. The frequency of intervention after a hemogram was 8.4% in infants <28 weeks, 4.6% in infants 28-31 6/7 weeks, and 0% in infants 32-34 weeks; this difference was found to be statistically significant (p = 0.02). The frequency of intervention after a hepatic panel was 4.2% in infants <28 weeks, 5.7% in infants 28-31 6/7 weeks, and 0% in infants 32-34 weeks, which was not found to be a statistically significant different. CONCLUSION: No interventions were undertaken post-routine laboratory testing in any infant 32-34 weeks and routine testing in this population may be unnecessary. Further studies are needed to elucidate if routine testing affects neonatal outcomes.

RESUMO

BACKGROUND: The aim of this study was to assess the general prevalence and the treatment policy of anemic patients referring to the Emergency Department (ED) of a tertiary care Hospital during 2015. STUDY DESIGN AND METHODS: The full blood cell count data from patients admitted to the ED for any reason,excepted for those with massive hemorrhage and multiple trauma, were studied. The prevalence of anemic patients and the degree of anemia were recorded, along with the transfusion policy applied. Transfusion appropriateness was retrospectively evaluated with a specific algorithm, that also considered the administered volume of red blood cells. A particular focus was made on patients with microcytosis about the physicians' awareness of the underlying iron deficiency and the consequent iron prescription. RESULTS: In a group of 22,329 patients the overall prevalence of anemia was 27.5% (6144 patients). Among the anemic patients, 281 / 6144 (4.6%) were transfused. The applied transfusion policy, as evaluated with the algorithm showed an overall good level of appropriateness (74.5% of transfusion episodes) but the appropriateness of the administered red blood cell mass was low (8.8%), due to over-transfusion. In microcytic transfused patients (mean MCV 69.0 ± SD 9.1), the iron balance tests were rarely ordered (22 patients out of 98-22.2%) and intravenous iron was prescribed in only 9 patients out of the 98 eligible (9.2%). CONCLUSION: The Patient Blood Management principles should be applied also in the ED setting, to promote a more appropriate and effective clinical approach to anemic patients.

RESUMO

Little is known about the prevalence of anaemia and associated factors in school children in Vietnam. In this cross-sectional study, we aimed to determine the prevalence of anaemia and its subtypes, and the associations of types of anaemia with demographic, socio-economic and anthropometric factors among 6-9-year-old primary school children in rural areas of Hai Phong City, Vietnam. Haemoglobin (Hb) and mean corpuscular volume (MCV) were measured, and demographic, socio-economic and anthropometric data were collected in 893 children from eight primary schools. The prevalence of anaemia (Hb < 115 g/L) was 12.9% (95% CI: 8.1%, 19.9%), microcytic anaemia (Hb < 115 g/L and MCV < 80 fL) was 7.9% (95% CI: 5.3%, 11.6%) and normocytic anaemia (Hb < 115 g/L and MCV 80-90 fL) was 5.3% (95% CI: 2.9%, 9.5%). No child presented with macrocytic anaemia (Hb < 115 g/L and MCV > 90 fL). Children who were underweight, wasted, or in anthropometric failure (either underweight, stunted or wasted) were more likely to be anaemic (all p ≤ 0.004), and specifically, to have normocytic anaemia (all p ≤ 0.006), than those who were not underweight, wasted or in anthropometric failure. Stunted children were more likely to be anaemic (p = 0.018) than those who were not stunted. Overweight/obese children were less likely to be anaemic (p = 0.026) or have normocytic anaemia (p = 0.038) compared with children who were not overweight/obese. No anthropometric status indicator was associated with the risk of microcytic anaemia. No demographic or socio-economic factor was associated with any type of anaemia. Anaemia remains a public health issue in rural areas in Hai Phong City, Vietnam, and future approaches for its prevention and control should target undernourished primary school children.

RESUMO

BACKGROUND: Anemia rates are over 60% in disadvantaged children yet there is little information about the quality of anemia care for disadvantaged children. METHODS: Our primary objective was to assess the burden and quality of anemia care for disadvantaged children and to determine how this varied by age and geographic location. We implemented a cross-sectional study using clinical audit data from 2287 Indigenous children aged 6-59 months attending 109 primary health care centers between 2012 and 2014. Data were analysed using multivariable regression models. RESULTS: Children aged 6-11 months (164, 41.9%) were less likely to receive anemia care than children aged 12-59 months (963, 56.5%) (adjusted odds ratio [aOR] 0.48, CI 0.35, 0.65). Proportion of children receiving anemia care ranged from 10.2% (92) (advice about 'food security') to 72.8% (728) (nutrition advice). 70.2% of children had a hemoglobin measurement in the last 12 months. Non-remote area families (115, 38.2) were less likely to receive anemia care compared to remote families (1012, 56.4%) (aOR 0.34, CI 0.15, 0.74). 57% (111) aged 6-11 months were diagnosed with anemia compared to 42.8% (163) aged 12-23 months and 22.4% (201) aged 24-59 months. 49% (48.5%, 219) of children with anemia received follow up. CONCLUSIONS: The burden of anemia and quality of care for disadvantaged Indigenous children was concerning across all remote and urban locations assessed in this study. Improved services are needed for children aged 6-11 months, who are particularly at risk.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the role of reticulocyte hemoglobin (Ret He) estimation in subtyping of anemia and to find the correlation of Ret He with the severity of anemia. METHODS: Ninety-four patients with rheumatic diseases with anemia were enrolled. Blood samples were taken to determine various parameters. Patients were divided into three groups: iron deficiency anemia, anemia of chronic disease with iron deficiency and anemia of chronic disease depending on the iron status and inflammatory markers. Analysis of variance and Pearson correlation coefficient were used. Receiver operating characteristic analysis was used to evaluate the accuracy of the parameters in differentiating anemia. RESULTS: Statistically significant differences among groups were seen with regard to parameters such as erythrocyte sedimentation rate, C-reactive protein, serum ferritin, total iron binding capacity, transferrin saturation, transferrin receptor protein, soluble transferrin receptor/log ferritin and Ret He. Ret He correlates with the subtype of anemia in patients with rheumatic disorders but it does not correlate with the severity of anemia. Soluble transferrin receptor/log ferritin, Ret He and serum ferritin values were the best parameters to differentiate between various groups. Ret He (pg) values of <24, 24-26.5 and >26.5, while serum ferritin levels (µg/L) of <35, 35-178 and >178 were highly sensitive and specific for iron deficiency anemia, anemia of chronic disease with iron deficiency and anemia of chronic disease groups, respectively. CONCLUSION: In cost constraints settings, a simple investigation like Ret He alone or with serum ferritin can help us to diagnose and differentiate between the different types of anemia accompanying rheumatological disorders without doing other serum iron studies and expensive tests like transferrin receptor protein which are not readily available.

RESUMO

Background The Taiwan Health Insurance Bureau has conducted a bundled payment system for hemodialysis reimbursement since 1995. The maximum dose of erythropoiesis-stimulating agents allowed by insurance is capped at 20 000 U of epoetin or 100 µg of darbepoetin alfa per month. Nephrologists have avoided the use of high dosages of erythropoiesis-stimulating agents to achieve a hemoglobin level of 10 to 11 g/dL by iron supplementation. The clinical impact of these policies on patients' outcomes is unknown. The authors aimed to assess the AIM-HD (Association of Anemia, Iron parameters, and Mortality among the prevalent Hemodialysis patients) Study in Taiwan. Methods and Results The AIM-HD study was conducted based on the Taiwan Renal Registry Data System. From 2001 to 2008, the authors enrolled 42 230 patients undergoing hemodialysis who were older than 20 years and had received hemodialysis for more than 12 months. Patient follow-ups occurred until death or December 31, 2008. During a study period of 8 years, 12 653 (30.0%) patients died. After multivariate adjustment, the authors found that a hemoglobin level <10 g/dL was significantly associated with higher risk for all-cause and cardiovascular deaths. Moreover, a serum ferritin level between 300 and 800 ng/mL and transferrin saturation value between 30% and 50% were associated with the lowest all-cause mortality. Conclusions The authors recommend avoiding a low hemoglobin level and maintaining serum ferritin between 300 and 800 ng/mL and transferrin saturation between 30% and 50%, which were associated with lower risks of all-cause mortality among patients undergoing hemodialysis receiving the restricted erythropoiesis-stimulating agent doses but prompt intravenous iron supplementation in Taiwan.

RESUMO

In Low and Lower-Middle-Income countries, the prevalence of anaemia in infancy remains high. In early childhood anaemia cause irreversible cognitive deficits and represents a higher risk of child mortality. The consequences of anaemia in infancy are a major barrier to overcome poverty traps. The aim of this study was to analyse, based on a multi-level approach, different factors associated with anaemia in children 6⁻23 months old based on recent available Standard Demographic Health Surveys (S-DHS). We identified 52 S-DHS that had complete information in all covariates of interest in our analysis between 2005 and 2015. We performed traditional logistic regressions and multilevel logistic regression analyses to study the association between haemoglobin concentrations and household, child, maternal, socio-demographic variables. In our sample, 70% of the 6⁻23 months-old children were anaemic. Child anaemia was strongly associated with maternal anaemia, household wealth, maternal education and low birth weight. Children fed with fortified foods, potatoes and other tubers had significantly lower rates of anaemia. Improving overall household living conditions, increasing maternal education, delaying childbearing and introducing iron rich foods at six months of age may reduce the likelihood of anaemia in toddlerhood.

RESUMO

BACKGROUND: Perioperative anemia is challenging during hospital stay because anemia and red blood cell (RBC) transfusions are associated with an increased morbidity and mortality. With the implementation of patient blood management (PBM), a preanesthesia assessment clinic to screen and treat anemia before elective surgery was institutionalized at Muenster University Hospital, Germany. The main objective of this study was to evaluate the association between treating preoperative anemic patients with intravenous iron (IVI) and (primarily) presurgical hemoglobin levels and (secondarily) use of RBCs and mortality. METHODS: Between April 1, 2014, and July 4, 2016, patients scheduled for elective surgery with a risk for RBC transfusions >10% in 2013 were screened for preoperative anemia and, if indicated, treated with IVI. Patients' data, time span between visit in the anesthesia/PBM clinic and surgery, demographic data, type of surgery, the difference of hemoglobin levels between visit and surgery, RBC transfusion, infectious-related International Classification of Disease codes during hospital stay, and 1-year survival were determined retrospectively by screening electronic data files. In addition, patients were interviewed about adverse events, health-related events, and infections via telephone 30, 90, and 365 days after visiting the anesthesia/PBM clinic. RESULTS: A total of 1101 patients were seen in the anesthesia/PBM clinic between days -28 and -1 (median [Q1-Q3], -3 days [-1, -9 days]) before elective surgery. Approximately 29% of patients presented with anemia, 46.8% of these anemic patients were treated with ferric carboxymaltose (500-1000 mg).In the primary analysis, hemoglobin levels at median were associated with a reduction between the visit in the anesthesia/PBM clinic and the surgery in all nonanemic patients on beginning of medical treatment (nonanemic patients at median -2.8 g/dL [-4, -0.9 g/dL], while anemic patients without IVI presented with median differences of -0.8 g/dL [-2, 0 g/dL] and anemic patients with IVI of 0 g/dL [-1.0, 0.5 g/dL]). Hemoglobin levels raised best at substitution 22-28 days before surgery (0.95 g/dL [-0.35, 1.18 g/dL]). Due to the selection criteria, transfusion rates were high in the cohort. Overall, there was no association between IVI treatment and the use of RBC transfusions (odds ratio for use of RBCs in anemic patients, no IVI versus IVI: 1.14; 95% confidence interval, 0.72-1.82). Patients treated with or without IVI presented a comparable range of International Classification of Disease codes related to infections. Telephone interviews indicated similar adverse events, health-related events, and infections. Cox regression analysis showed an association between anemia and reduced survival, regardless of IVI. CONCLUSIONS: An anemia clinic within the preanesthesia assessment clinic is a feasible and effective approach to treat preoperative anemia. The IVI supplementation was safe but was associated with decreased RBC transfusions in gynecology/obstetric patients only. The conclusions from this retrospective analysis have to be tested in prospective, controlled trials.

RESUMO

Anemia is one of the most common health problems in both industrialized and developing countries. It has been recognized by the World Health Organization as an important disorder leading to significant health care burden. Laboratory testing plays a significant role in the diagnosis of most types of anemia since the clinical diagnosis may not always be straightforward, especially with multiple underlying conditions. Once the existence of anemia is established, the cause must be determined to enable selection of a specific and effective therapy. Various hematologic parameters and biochemical tests can be used in combination with patient clinical history to identify the most likely causes of anemia.

RESUMO

Both anemia and sickle cell disease (SCD) are highly prevalent across sub-Saharan Africa, and limited resources exist to diagnose these conditions quickly and accurately. The development of simple, inexpensive, and accurate point-of-care (POC) assays represents an important advance for global hematology, one that could facilitate timely and life-saving medical interventions. In this prospective study, Robust Assays for Point-of-care Identification of Disease (RAPID), we simultaneously evaluated a POC immunoassay (Sickle SCAN™) to diagnose SCD and a first-generation POC color-based assay to detect anemia. Performed at Bugando Medical Center in Mwanza, Tanzania, RAPID tested 752 participants (age 1 day to 20 years) in four busy clinical locations. With minimally trained medical staff, the SCD POC assay diagnosed SCD with 98.1% sensitivity and 91.1% specificity. The hemoglobin POC assay had 83.2% sensitivity and 74.5% specificity for detection of severe anemia (Hb ≤ 7 g/dL). Interobserver agreement was excellent for both POC assays (r = 0.95-0.96). Results for the hemoglobin POC assay have informed the second-generation assay design to be more suitable for low-resource settings. RAPID provides practical feasibility data regarding two novel POC assays for the diagnosis of anemia and SCD in real-world field evaluations and documents the utility and potential impact of these POC assays for sub-Saharan Africa.
