Abstract
BACKGROUND The high prevalence of anemia in resource-constrained settings calls for easy-to-use, inexpensive screening tools. The Sanguina Smartphone App, an innovative tool for non-invasive hemoglobin estimation via color-sensitive, algorithm-based analysis of fingernail bed images, was validated in the United States. This study evaluates the performance of the App in a population with different socio-economic, ethnic, demographic and cultural composition in rural Bihar, India. METHODS For 272 mainly adult patients of a private health centre, hemoglobin measurement with the App is compared with the gold standard laboratory blood analysis. For a second sample of 179 children attending pre-schools, hemoglobin measurement with the App is compared to the results of the HemoCue Hb 301, a point-of-care device using a small blood sample, serving as the reference standard for field-based settings. RESULTS The App reaches ±4.43 g/dl accuracy and 0.38 g/dl bias of comparator values in the clinic-based sample, and ±3.54 g/dl and 1.30 g/dl, respectively in the pre-school sample. After retraining the algorithm with the collected data, the validity of the upgraded version is retested showing an improved performance (accuracy of ±2.25 g/dl, bias of 0.25 g/dl), corresponding to the results of the original validation study from the United States. CONCLUSIONS The initial version of the App does not achieve the accuracy needed for diagnosis or screening. After retraining the algorithm, it achieves an accuracy sufficient for screening. The improved version with the potential for further adaptions is a promising easy-to-use, inexpensive screening tool for anemia in resource-constrained point-of-care settings.

Abstract
BACKGROUND Iron deficiency (ID) is associated with negative health outcomes in older adults. However, data on the impact of ID on the number of hospitalizations and length of hospital stay (LOS) is lacking. OBJECTIVE To explore the associations between baseline ID and the number of hospitalizations and between baseline ID and at least one LOS ≥5 days in community-dwelling older adults. METHODS This is a secondary observational analysis of a randomized controlled trial including 2157 community-dwelling adults aged ≥70 years without major diseases at baseline. The main exposure was defined as ID (soluble transferrin receptor [sTfR] concentrations >28.1 nmol/L) at baseline. The primary outcome was the number of hospitalizations over a 3-year follow-up. The secondary outcome was having at least one LOS ≥5 days over the study period among individuals with one or more hospitalizations. Interaction between ID and anemia (hemoglobin <130 g/L for men and <120 g/L for women) was also investigated. RESULTS Baseline sTfR concentration was determined in 2141 participants (median age 74.0 years). At 3 year, 1497 hospitalizations were reported with an incidence rate of hospitalization of 0.26 per person-year (95% CI: 0.24, 0.28). Overall, baseline ID was associated with a 24% increased incidence rate of hospitalization (incidence rate ratio: 1.24; 95% CI: 1.05, 1.45) over 3 years. This association was independent of anemia status at baseline since the interaction between ID and anemia at baseline was not significant. Moreover, ID was not significantly associated with having a LOS ≥5 days (OR: 1.40; 95% CI: 1.00, 1.97) among participants with at least one hospitalization over 3 years. CONCLUSIONS ID is associated with increased hospitalization rate and not associated with LOS ≥5 days among generally healthy older adults. Efforts to minimize ID in older adults may improve overall health and optimize healthcare costs.

Abstract
BACKGROUND AND AIM Iron deficiency is associated with increased morbidity and mortality in older adults. However, data on its prevalence and incidence among older adults is limited. The aim of this study was to investigate the prevalence and incidence of iron deficiency in European community-dwelling older adults aged ≥ 70 years. METHODS Secondary analysis of the DO-HEALTH trial, a 3-year clinical trial including 2157 community-dwelling adults aged ≥ 70 years from Austria, France, Germany, Portugal and Switzerland. Iron deficiency was defined as soluble transferrin receptor (sTfR) > 28.1 nmol/L. Prevalence and incidence rate (IR) of iron deficiency per 100 person-years were examined overall and stratified by sex, age group, and country. Sensitivity analysis for three commonly used definitions of iron deficiency (ferritin < 45 μg/L, ferritin < 30 μg/L, and sTfR-ferritin index > 1.5) were also performed. RESULTS Out of 2157 participants, 2141 had sTfR measured at baseline (mean age 74.9 years; 61.5% women). The prevalence of iron deficiency at baseline was 26.8%, and did not differ by sex, but by age (35.6% in age group ≥ 80, 29.3% in age group 75-79, 23.2% in age group 70-74); P < 0.0001) and country (P = 0.02), with the highest prevalence in Portugal (34.5%) and the lowest in France (24.4%). As for the other definitions of iron deficiency, the prevalence ranged from 4.2% for ferritin < 30 µg/L to 35.3% for sTfR-ferritin index > 1.5. Occurrences of iron deficiency were observed with IR per 100 person-years of 9.2 (95% CI 8.3-10.1) and did not significantly differ by sex or age group. The highest IR per 100 person-years was observed in Austria (20.8, 95% CI 16.1-26.9), the lowest in Germany (6.1, 95% CI 4.7-8.0). Regarding the other definitions of iron deficiency, the IR per 100 person-years was 4.5 (95% CI 4.0-4.9) for ferritin < 45 µg/L, 2.4 (95% CI 2.2-2.7) for ferritin < 30 µg/L, and 12.2 (95% CI 11.0-13.5) for sTfR-ferritin index > 1.5. CONCLUSIONS Iron deficiency is frequent among relatively healthy European older adults, with people aged ≥ 80 years and residence in Austria and Portugal associated with the highest risk.

Abstract
The implementation of patient blood management (PBM) is increasingly becoming standard in operative medicine. Recently, interest has also been shown for the vulnerable collective of pregnant women and neonates. As the information regarding anesthesiological procedures for pregnant women and the peripartum period including an informed consent process should be carried out long before childbirth, this provides a good possibility in this connection to incorporate PBM. An anesthesiological risk estimation as well as the diagnostic workup and treatment of potential anemia should be carried out during the pregnancy. Furthermore, loss of blood in anticipation of bleeding complications should be reduced by interdisciplinary preventive measures and an individually coordinated postpartum care should be organized. This results in an early diagnosis of anemia or iron deficiency with subsequent treatment also postpartum, analogous to the prepartum period.

Abstract
Background The longitudinal association between iron deficiency and inflammatory biomarkers levels has not been fully explored among relatively healthy older adults. Aims To assess whether iron deficiency at baseline and at any yearly follow-up time point, with or without anemia, was associated with changes from baseline in high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) levels over 3 years. Methods This is a post-hoc observational analysis of DO-HEALTH, a double-blind, randomized controlled trial including 2157 European community-dwelling adults age 70+. The outcomes were changes from baseline in hs-CRP and IL-6 levels, measured at 12, 24, and 36 months of follow-up. Iron deficiency was defined by soluble transferrin receptor levels > 28.1 nmol/L and baseline anemia by hemoglobin levels < 130 g/L for men and < 120 g/L for women. Results In total, 2141 participants were included in the analyses (mean age: 74.9 years, 61.5% of women, 26.8% with iron deficiency). Baseline iron deficiency was associated with greater increase in IL-6 levels (mean difference in change: 0.52 ng/L, 95%CI 0.03–1.00, P = .04) over 3 years. Iron deficiency at any yearly time point was associated with higher increases in hs-CRP (mean difference in change: 1.62 mg/L, 95%CI 0.98–2.26, P < .001) and IL-6 levels (mean difference in change: 1.33 ng/L, 95%CI 0.87–1.79, P < .001) over 3 years. No significant interaction between iron deficiency and anemia was found, suggesting that the results are independent of the anemic status. Conclusions These findings suggest that iron deficiency may play a role in low-grade chronic inflammation among relatively healthy older adults.

Abstract
Patient Blood Management (PBM) aims to diagnose and treat preoperative anaemia, avoid unnecessary blood loss, and enable rational use of blood products. Due to various limitations, treatment of preoperative anaemia has been successful in only a few German hospitals to date. Thus, the peri- and postoperative phase is increasingly becoming important for implementing various preventive and therapeutic measures for the treatment of (postoperative) anaemia. These will be comprehensively presented in the following.

Abstract
OBJECTIVES To assess if baseline iron deficiency, with or without anemia, is associated with incident infections over 3 years among community-dwelling older adults. DESIGN Prospective secondary analysis of DO-HEALTH, a 3-year randomized, double-blind controlled trial. SETTING AND PARTICIPANTS 2157 community-dwelling adults age 70+ from 5 European countries with good cognitive function and mobility and no major health events in the 5 years prior to enrollment Measurements: Incident infections, their severity and type were recorded every 3 months throughout the 3-year follow-up. Iron deficiency was defined as soluble transferrin receptor (sTfR) levels > 28.1 nmol/l and anemia as hemoglobin levels < 120 g/l for women and 130 g/l for men. We applied negative binomial mixed effects regression models with random effects for countries, and controlling for treatment allocation, age, sex, body mass index, polypharmacy, number of comorbidities, smoking status, living situation, alcohol intake, frailty status, and physical activity levels. A pre-defined stratified analysis was performed to explore if the associations between iron deficiency and infections were consistent by baseline anemia status. RESULTS In total, 2141 participants were included in the analyses (mean age 74.9 years, 61.5% of women, 26.8% with iron deficiency). Across all participants, baseline iron deficiency was not associated with incident overall infections, but was associated with a 63% greater rate of incident severe infections requiring hospitalization (incidence rate ratio [IRR] 1.63, 95% Confidence Interval [CI] 1.11-2.41, p=0.01). This association was more pronounced among the 2000 participants who did not have anemia at baseline (IRR=1.80, 95% CI 1.20-2.69, p=0.005). CONCLUSION Based on this prospective study among generally healthy European community-dwelling older adults, iron deficiency was not associated with the incidence rate of overall infections but may increase the incidence of severe infections. Intervention studies are needed to prove the causality of this observation.

Abstract
INTRODUCTION Postoperative anaemia can affect more than 90% of patients undergoing major surgeries. Patients develop an absolute iron deficiency in the face of significant blood loss or preoperative anaemia and major surgery. Studies have shown the negative impact of these factors on transfusion requirements, infections, increased hospitalisation and long-term morbidities. AIM OF THE STUDY The research was performed to determine the correlation between intravenous iron administration in the postoperative period and improved haemoglobin correction trend. MATERIAL AND METHODS A prospective study was conducted to screen and treat iron deficiency in patients undergoing major surgery associated with significant bleeding. For iron deficiency anaemia screening, in the postoperative period, the following bioumoral parameters were assessed: haemoglobin, serum iron, transferrin saturation (TSAT), and ferritin, direct serum total iron-binding capacity (dTIBC), mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH). In addition, serum glucose, fibrinogen, urea, creatinine and lactate values were also collected. RESULTS Twenty-one patients undergoing major surgeries (52,38% were emergency and 47,61% elective interventions) were included in the study. Iron deficiency, as defined by ferritin 100-300 μg/L along with transferrin saturation (TSAT) < 20 %, mean corpuscular volume (MVC) < 92 fL, mean corpuscular haemoglobin (MCH) < 33 g/dL, serum iron < 10 μmol/L and direct serum total iron-binding capacity (dTIBC) > 36 μmol/L, was identified in all cases. To correct the deficit and optimise the haematological status, all patients received intravenous ferric carboxymaltose (500-1000 mg, single dose). Using Quadratic statistical analysis, the trend of haemoglobin correction was found to be a favourable one. CONCLUSION The administration of intravenous ferric carboxymaltose in the postoperative period showed the beneficial effect of this type of intervention on the haemoglobin correction trend in these groups of patients.

Abstract
PURPOSE OF REVIEW In the past years, patient blood management (PBM) has evolved to improve patient's care and safety. Anemia is one of the most common medical diseases in the world and is an independent risk factor for morbidity and mortality. Iron deficiency is the main cause for anemia and constitutes a potentially preventable condition with a great impact on surgical outcome. However, preoperative anemia management is not yet established in most hospitals. Changing workflows and re-thinking is challenging. Numerous published studies confirmed the positive effect of preoperative anemia diagnosis and treatment recently. RECENT FINDINGS Iron supplementation in iron-deficient anemic (IDA) patients reduce the need for allogenic blood transfusion thereby improving perioperative outcome. SUMMARY Since the introduction of PBM programs, important movements towards early detection and therapy of preoperative anemia have been observed. However, preoperative anemia management is not implemented on a large scale as many healthcare professionals are not aware of the most recent findings in the field. Preoperative anemia management, particularly iron supplementation in IDA patients, has proven to be highly effective and has a tremendous effect on patient safety and outcome.

Zinc Protoporphyrin Is a Reliable Marker of Functional Iron Deficiency in Patients with Inflammatory Bowel Disease. Diagnostics (Basel) 2021; 11:diagnostics11020366. [PMID: 33670067 PMCID: PMC7926353 DOI: 10.3390/diagnostics11020366] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Revised: 02/07/2021] [Accepted: 02/18/2021] [Indexed: 12/21/2022] Open
Abstract
Iron deficiency (ID) is a common manifestation of inflammatory bowel disease (IBD), arising primarily due to chronic inflammation and/or blood loss. There is no gold standard for ID diagnosis, which is often complicated by concomitant inflammation. Zinc protoporphyrin (ZnPP) correlates with parameters of iron homeostasis and has been identified as a promising marker for ID, irrespective of inflammation. We investigated the diagnostic performance of ZnPP in ID, iron deficiency anemia, anemia of chronic disease and mixed anemia in a cross-sectional study in 130 patients with IBD. Different parameters were compared by receiver operator characteristic (ROC) analysis as detectors of iron-restricted erythropoiesis (IRE). IRE was detected in 91 patients (70.0%); fifty-nine (64.8%) had absolute ID and 23 (25.4%) functional ID. When inflammation was present, ZnPP was a more reliable sole biomarker of IRE than MCV, transferrin saturation (TSAT) or ferritin (AUC; 0.855 vs. 0.763, 0.834% and 0.772, respectively). The specificity of TSAT was significantly lower than ZnPP when inflammation was present (38% vs. 71%, respectively). We conclude that ZnPP is a reliable biomarker of functional ID in patients with IBD and more dependable than ferritin or TSAT, which are influenced by chronic inflammation. We propose that ZnPP may also have utility in patients with other chronic diseases.
