Abstract
Anemia causes hypo-oxygenation in the brain, which could lead to cognitive disorders. We examined dietary iron intake as well as anemia markers (i.e., hemoglobin, hematocrit, mean corpuscular volume) and diabetes coexistence in relation to neuropsychological function and quality of life. In this study, 6117 community-dwelling adults aged 55-75 years (men) and 60-75 years (women) with overweight/obesity and metabolic syndrome were involved. We performed the Mini-Mental State Examination (MMSE), the Trail Making Test parts A and B (TMT-A/B), Semantic Verbal Fluency of animals (VFT-a), Phonological Verbal Fluency of letter P (VFT-p), Digit Span Test (DST), the Clock Drawing Test (CDT), and the Short Form-36 Health Survey (SF36-HRQL test). Dietary iron intake did not influence neuropsychological function or quality of life. However, anemia and lower levels of anemia markers were associated with worse scores in all neurophysiological and SF36-HRQL tests overall, but were especially clear in the MMSE, TMT-B (cognitive flexibility), and the physical component of the SF36-HRQL test. The relationships between anemia and diminished performance in the TMT-A/B and VFT tasks were notably pronounced and statistically significant solely among participants with diabetes. In brief, anemia and reduced levels of anemia markers were linked to inferior cognitive function, worse scores in different domains of executive function, as well as a poorer physical, but not mental, component of quality of life. It was also suggested that the coexistence of diabetes in anemic patients may exacerbate this negative impact on cognition. Nevertheless, dietary iron intake showed no correlation with any of the outcomes. To make conclusive recommendations for clinical practice, our findings need to be thoroughly tested through methodologically rigorous studies that minimize the risk of reverse causality.

Abstract
Background Inflammation has several effects in the geriatrics with reference to iron deficiency anemia (IDA), anemia of chronic disease (ACD), and unexplained anemia (UA). Whether hyperinflammation is part of their pathogenesis or just incidental is unknown. Data are limited regarding inflammatory patterns in IDA, ACD, and UA in anemic geriatrics and inflammation as a component of UA. There is little known about the overlap of inflammation between ACD and UA. Objective The study was undertaken to find the proportion of anemic geriatric patients, aged ≥60 years with raised serum levels of inflammatory markers and their study within IDA, ACD, and UA. Materials and Methods Seventy-five anemic geriatric patients were evaluated for raised serum levels of inflammatory markers: high sensitive C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) along with serum ferritin (SF). Results Raised markers were seen in 94.7% of anemic geriatric patients.IL-8 was raised most frequently followed by TNF-α, IL-6, hsCRP, and SF. No distinct inflammatory profile could be elicited between ACD and UA. The hyperinflammatory profile irrespective of the underlying etiology of geriatric anemia suggests that aging per se is pro-inflammatory state. Conclusion Geriatric anemia can be thought to develop on background of subclinical low-grade inflammation along with superimposed nutritional deficiencies or chronic diseases.

Causes of Anemia in Polish Older Population-Results from the PolSenior Study. Cells 2021; 10:cells10082167.

Abstract
Vitamin B12, folate, iron deficiency (IDA), chronic kidney disease (CKD), and anemia of inflammation (AI) are among the main causes of anemia in the elderly. WHO criteria of nutritional deficiencies neglect aging-related changes in absorption, metabolism, and utilization of nutrients. Age-specific criteria for the diagnosis of functional nutritional deficiency related to anemia are necessary. We examined the nationally representative sample of Polish seniors. Complete blood count, serum iron, ferritin, vitamin B12, folate, and renal parameters were assessed in 3452 (1632 women, 1820 men) participants aged above 64. Cut-off points for nutritional deficiencies were determined based on the WHO criteria (method-A), lower 2.5 percentile of the studied population (method-B), and receiver operating characteristic (ROC) analysis (method-C). Method-A leads to an overestimation of the prevalence of vitamin B12 and folate deficiency, while method-B to their underestimation with over 50% of unexplained anemia. Based on method-C, anemia was classified as nutritional in 55.9%. In 22.3% of cases, reasons for anemia remained unexplained, the other 21.8% were related to CKD or AI. Mild cases were less common in IDA, and more common in non-deficiency anemia. Serum folate had an insignificant impact on anemia. It is necessary to adopt the age-specific criteria for nutrient deficiency in an old population.

Abstract
Anemia is a very common complicating feature of chronic kidney disease (CKD) in the elderly. Noninvasive assessment of renal function in the elderly may include several equations although they may actually underestimate the true glomerular filtration rate (GFR). In summary, anemia in the setting of CKD in the elderly is generally underrecognized and undertreated, leading to associations of increased morbidity and mortality. The likelihood of benefits of treatment of anemia in this rapidly increasing subset of patients with CKD remains very high.

Abstract
Background Anemia has a myriad of causes and its prevalence is growing. Anemia is associated with increased all-cause hospitalization and mortality in community-dwelling individuals above age 65 years. Our aim was to determine the prevalence and severity of anemia in adult patients in our primary care office and to determine the relationship between anemia and medical comorbidities. Methods Electronic medical records of 499 adult patients in our suburban internal medicine office were reviewed who had had at least one hemoglobin value and did not undergo moderate to high-risk surgery in the preceding 30 days. Results About one-fifth (21.1%) of the patients had anemia. The mean age of patients with anemia was 62.6 years. Among all patients with anemia, 20.3% were males and 79.6% were females. Of these patients, 60.1% had mild anemia (hemoglobin 11 - 12.9 g/dL) and 39.8% had moderate anemia (hemoglobin 8 - 10.9 g/dL). For every year of increase in age, there was 1.8% increased odds of having anemia. African-American race had 5.2 times greater odds of having anemia than the Caucasian race. Hispanic race had 3.2 times greater odds of having anemia compared to the Caucasian race. Patients with anemia had a greater average number of comorbidities compared to patients without anemia (1.74 and 0.96, respectively; P < 0.05). There was a statistically greater percentage of patients with essential hypertension, hypothyroidism, chronic kidney disease, malignancy, rheumatologic disease, congestive heart failure, and coronary artery disease in the anemic population as compared to the non-anemic population. Of the patients, 41% with mild anemia and 62% with moderate anemia underwent additional diagnostic studies. Of the patients, 14.8% had resolution of anemia without therapy in 1 year, 15.7% were on iron replacement therapy, and 6.5% were on cobalamin therapy. No specific etiology of anemia was found in 24% of patients. Conclusion A higher prevalence of anemia was associated with advancing age, African-American and Hispanic ethnicity, and comorbidities, such as essential hypertension, hypothyroidism, chronic kidney disease, malignancy, rheumatologic disease, congestive heart failure, and coronary artery disease. It is important to be aware of the demographic factors and their relationship to anemia in primary care.

Abstract
Anemia in older adults is a risk factor for numerous negative outcomes. There is no standard definition, but in most studies, anemia is defined as a hemoglobin value <12 g/dL for women and <13 g/dL for men. Absolute iron deficiency anemia is defined as the combination of anemia and the absence of total body iron. Serum ferritin is the most frequently used diagnostic parameter, but its concentration increases with age and in the presence of inflammatory diseases. Other laboratory tests, such as transferrin saturation, soluble transferrin receptor and the soluble transferrin receptor/ferritin index might provide useful information, but there is a wide variety in the cut-off values and interpretation of the results. Recent research regarding hepcidin as a central regulator of iron homeostasis is promising, but it has not been used yet for the routine diagnosis of iron deficiency anemia. In older iron deficiency anemia patients, an esophagogastroduodenoscopy and colonoscopy should be initiated in order to identify the underlying bleeding cause. CT colonography can replace a colonoscopy, and in specific cases, a video capsule is recommended. It remains crucial to keep in mind which potential benefits might be expected from these investigations in this vulnerable population, taking into account the comorbidity and life expectancy, and one should discuss in advance the possible therapeutic options and complications with the patient, a family member or a proxy. Oral iron administration is the standard treatment, but parenteral iron is a convenient and safe way to provide the total iron dose in one or a few sessions. Geriatr Gerontol Int 2018; 18: 373-379.

Abstract
A specific cause of anemia cannot be identified in many elderly patients. Erythropoiesis-stimulating agents (ESAs) may play a role in treating these patients with anemia of unknown etiology (AUE). This study examines hemoglobin and cardiovascular outcomes among elderly anemic patients treated with ESAs. We conducted a retrospective cohort study that included all anemic patients older than age 60 years who had erythropoietin (EPO) measured between 2005 and 2013 at a single center. Three independent reviewers used defined criteria to assign each patient's anemia to 1 of 4 groups: chronic kidney disease (CKD), myelodysplastic syndrome, AUE, or other etiology. Logistic regression was used to compare treatment response (defined per the International Working Group response criteria in myelodysplasia). Adjusted Cox regression analysis was used to calculate the cardiovascular event hazard ratios associated with ESA treatment. A total of 570 patients met the inclusion criteria, of whom 101 received ESAs. There was a nonstatistically significant but quantitatively better response in AUE (47%) and CKD (54%) compared with other etiologies (22%). The adjusted odds ratio for response in AUE compared with other etiologies was 3.3 (95% confidence interval, 0.838-13.0). A baseline EPO level <200 IU/L independently predicted treatment response. There was no statistically significant difference in cardiovascular events or cardiovascular event-free survival between the treated and untreated groups after adjusting for confounders. Our results suggest that ESAs may effectively treat AUE, and responses may be similar to those in CKD. We could not detect a statistically significant increase in cardiovascular events in the studied cohort.

Abstract
BACKGROUND & AIMS Only a limited number of studies have compared nursing home and community residing elderly in terms of health-related issues. The present study aimed to compare nutritional status and its associated factors between nursing home residents and community-dwelling seniors. METHODS In this case-control, age- and gender-matched study in Tabriz (East Azarbaijan, Iran), elderly subjects aged 65 years and older were recruited from nursing homes (n = 76) and community (n = 88). Anthropometric, blood pressure and dietary intake measurements, as well as biochemical assays were performed. Nutritional status (Mini Nutritional Assessment: MNA), cognitive function (Mini Mental State Examination: MMSE) and physical performance (Barthel Index) were assessed and compared between the two settings. RESULTS Nursing home residents had significantly lower body mass index (BMI), limbs, waist and hip circumferences, and diastolic blood pressure. Caloric and protein intake of the groups were similar, while nursing home residents received lower amounts of many micronutrients and saturated fats and higher polyunsaturated fats. MNA, MMSE and Barthel index scores were significantly different between the groups, all of them in favor of the free living elderly (p < 0.001, p < 0.001 and p = 0.014, respectively). Laboratory tests revealed significantly lower levels of hemoglobin, folate, fasting blood sugar, insulin, albumin, prealbumin, creatinine and uric acid in the nursing home group; however, mean cell volume (MCV) and HDL-cholesterol were higher in this group. CONCLUSION Elderly people living in nursing homes have lower BMI, suffer from many nutritional deficiencies and are predisposed to malnutrition, impaired cognition and deteriorating physical performance, compared to community dwelling seniors.

Abstract
Background In many elderly patients with anemia, a specific cause cannot be identified. This study investigates whether erythropoietin levels are inappropriately low in these cases of “anemia of unknown etiology” and whether this trend persists after accounting for confounders. Methods This study includes all anemic patients over 60 years old who had erythropoietin measured between 2005 and 2013 at a single center. Three independent reviewers used defined criteria to assign each patient’s anemia to one of ten etiologies: chronic kidney disease, iron deficiency, chronic disease, confirmed myelodysplastic syndrome (MDS), suspected MDS, vitamin B12 deficiency, folate deficiency, anemia of unknown etiology, other etiology, or multifactorial etiology. Iron deficiency anemia served as the comparison group in all analyses. We used linear regression to model the relationship between erythropoietin and the presence of each etiology, sequentially adding terms to the model to account for the hemoglobin concentration, estimated glomerular filtration rate (eGFR) and Charlson Comorbidity Index. Results A total of 570 patients met the inclusion criteria. Linear regression analysis showed that erythropoietin levels in chronic kidney disease, anemia of chronic disease and anemia of unknown etiology were lower by 48%, 46% and 27%, respectively, compared to iron deficiency anemia even after adjusting for hemoglobin, eGFR and comorbidities. Conclusions We have shown that erythropoietin levels are inappropriately low in anemia of unknown etiology, even after adjusting for confounders. This suggests that decreased erythropoietin production may play a key role in the pathogenesis of anemia of unknown etiology.

Abstract
Anemia is a common diagnosis in the geriatric population, especially in institutionalized and hospitalized elderly. Most common etiologies for anemia in elderly people admitted to a geriatric ward are iron-deficiency anemia and anemia associated with chronic disease. Determination of serum ferritin is the most used assay in the differential diagnosis, despite low sensitivity and moderate specificity. New insights into iron homeostasis lead to new diagnostic assays such as serum hepcidin, serum transferrin receptor and reticulocyte hemoglobin equivalent.Importance of proper diagnosis and treatment for this population is large since there is a correlation between anemia and morbidity - mortality. Anemia is usually defined as hemoglobin less than 12 g/dl for women and less than 13 g/dl for men. There is no consensus for which hemoglobinvalue an investigation into underlying pathology is obligatory. This needs to be evaluated depending on functional condition of the patient.

Abstract
BACKGROUND The objective of this study is to examine associations between Hb levels and sarcopenia, low muscle strength, functional measures, and activities of daily living (ADL) and instrumental ADL (IADL) disabilities in older Australian men. METHODS Men aged 70 years and older (2005-2007) from the Concord Health and Ageing in Men Project were assessed at baseline (n = 1,705), 2 years (n = 1,367), and 5 years (n = 958). The main outcome measurements were walking speed, muscle strength, ADL and IADL disabilities, and sarcopenia using the Foundation for the National Institutes of Health criteria (low appendicular lean mass adjusted for body mass index < 0.789 and poor grip strength < 26kg). Analysis was performed using Hb levels as a continuous measure, unadjusted and adjusted by age, income, body mass index, measures of health, estimated glomerular function, inflammatory markers, and medication use. Receiver operating characteristic curve analysis was performed to determine a threshold of Hb for each outcome. RESULTS In cross-sectional and longitudinal analysis, for every 1g/dL increase in Hb, there was a significant reduction in risk of sarcopenia, slow walking speed, poor grip strength, inability to perform chair stands, and ADL and IADL disabilities in unadjusted, age-adjusted, and multivariate-adjusted analysis. The highest value of the Youden Index for Hb was 14.2g/dL for sarcopenia and grip strength, 14.5g/dL for walking speed, and 14.4g/dL for all other outcomes. CONCLUSION Declines in Hb levels over time are associated with poor functional outcomes. The risks and benefits of interventions to increase Hb among older men warrant further investigation to differentiate whether this is an active contributor to age-related debility or a passive biomarker of it.

Abstract
Anemia is a common finding in elderly individuals. Several studies have shown a strong relationship between anemia, morbidity and mortality, suggesting anemia as a significant independent predictor of adverse outcome in elderly hospitalized patients. The pathophisiology of anemia in the elderly is not yet completely understood. Several mechanisms are involved. We investigated the prevalence of anemia in a cohort of 193 elderly patients admitted to the Internal Medicine Ward of Ca'Granda Policlinico Hospital along 6 months, and its relationship to comorbidities and to the length of hospitalization. Anemia was classified according to the WHO criteria. The majority of patients (48 %) had a mildmoderate, normocytic anemia; severe anemia was found in 8 out of 92 anemic patients. In a subgroup of patients erythropoietin was tested and resulted statistically higher if compared to non-anemic controls (p = 0.003). Considering the most common cause of anemia, nutritional deficiency, chronic renal disease and anemia of chronic disease were found respectively in 36, 15 and 25 % of cases. Unexplained anemia was diagnosed in 24 % of patients, according to the literature. Anemia was independently associated with increased length of hospital stay. Our study confirmed a high prevalence of anemia in elderly patients, and its association with a higher number of comorbidities and a longer stay. A correct clinical approach to anemia in elderly hospitalized patients is essential, considering its negative impact on patients' quality of life, and its social burden in term of healthcare needs and costs.

Abstract
Anemia is a global public health problem affecting both developing and developed countries at all ages. According to the World Health Organization (WHO), anemia is defined as hemoglobin (Hb) levels <12.0 g/dL in women and <13.0 g/dL in men. However, normal Hb distribution varies not only with sex but also with ethnicity and physiological status. New lower limits of normal Hb values have been proposed, according to ethnicity, gender, and age. Anemia is often multifactorial and is not an independent phenomenon. For the classification and diagnosis the hematologic parameters, the underlying pathological mechanism and patient history should be taken into account. The aging of population, especially in Western countries, causes an increase of anemia in elderly people. In this population, anemia, recently defined by levels of Hb <12 g/dL in both sexes, is mostly of mild degree (10-12 g/dL). Understanding the pathophysiology of anemia in this population is important because it contributes to morbidity and mortality. In one third of the patients, anemia is due to nutritional deficiency, including iron, folate, or vitamin B12 deficiency; moreover, anemia of chronic disease accounts for about another third of the cases. However, in one third of patients anemia cannot be explained by an underlying disease or by a specific pathological process, and for this reason it is defined "unexplained anemia". Unexplained anemia might be due to the progressive resistance of bone marrow erythroid progenitors to erythropoietin, and a chronic subclinical pro-inflammatory state.

Abstract
Background Circulating myeloid cells are important mediators of the inflammatory response, acting as a major source of resident tissue antigen presenting cells and serum cytokines. They represent a number of distinct subpopulations whose functional capacity and relative concentrations are known to change with age. Little is known of these changes in the very old and physically frail, a rapidly increasing proportion of the North American population. Design In the following study the frequency and receptor expression of blood monocytes and dendritic cells (DCs) were characterized in a sample of advanced-age, frail elderly (81–100 yrs), and compared against that of adults (19–59 yrs), and community-dwelling seniors (61–76 yrs). Cytokine responses following TLR stimulation were also investigated, as well as associations between immunophenotyping parameters and chronic diseases. Results The advanced-age, frail elderly had significantly fewer CD14(++) and CD14(+)CD16(+), but not CD14(++)CD16(+) monocytes, fewer plasmacytoid and myeloid DCs, and a lower frequency of monocytes expressing the chemokine receptors CCR2 and CX3CR1. At baseline and following stimulation with TLR-2 and -4 agonists, monocytes from the advanced-age, frail elderly produced more TNF than adults, although the overall induction was significantly lower. Finally, monocyte subset frequency and CX3CR1 expression was positively associated with dementia, while negatively associated with anemia and diabetes in the advanced-age, frail elderly. Conclusions These data demonstrate that blood monocyte frequency and phenotype are altered in the advanced-age, frail elderly and that these changes correlate with certain chronic diseases. Whether these changes contribute to or are caused by these conditions warrants further investigation.

Abstract
Anemia is now recognized as a risk factor for a number of adverse outcomes in the elderly, including hospitalization, morbidity, and mortality. What constitutes appropriate evaluation and management for an elderly patient with anemia, and when to initiate a referral to a hematologist, are significant issues. Attempts to identify suggested hemoglobin levels for blood transfusion therapy have been confounded for elderly patients with their co-morbidities. Since no specific recommended hemoglobin threshold has stood the test of time, prudent transfusion practices to maintain hemoglobin thresholds of 9-10 g/dL in the elderly are indicated, unless or until evidence emerges to indicate otherwise.

Abstract
BACKGROUND Studies conducted in high income countries have shown that anaemia is a common medical condition among older people, but such data are scarce in Africa. The objectives of this study were to estimate the prevalence, types, risk factors and clinical correlates of anaemia in older people. METHODS Participants were aged (≥ 50) years recruited from a general population cohort from January 2012 to January 2013. Blood samples were collected for assessing hemoglobin, serum ferritin, serum vitamin B12, serum folate, C-reactive protein, malaria infection and stool samples for assessment of hookworm infection. HIV status was assessed using an algorithm for HIV rapid testing. Questionnaires were used to collect data on sociodemographic characteristics and other risk factors for anaemia. RESULTS In total, 1449 people participated (response rate 72.3%). The overall prevalence of anaemia was 20.3 % (95% CI 18.2-22.3%), and this was higher for males (24.1%, 95% CI=20.7-27.7%) than females (17.5%, 95% CI=15.0-20.1%). In males, the prevalence of anaemia increased rapidly with age almost doubling between 50 and 65 years (p-trend<0.001). Unexplained anaemia was responsible for more than half of all cases (59.7%). Anaemia was independently associated with infections including malaria (OR 3.49, 95% CI 1.78-6.82), HIV (OR 2.17, 1.32-3.57) heavy hookworm infection (OR 3.45, 1.73-6.91), low fruit consumption (OR 1.55, 1.05-2.29) and being unmarried (OR 1.37 , 95% CI 1.01-1.89). However, the odds of anaemia were lower among older people with elevated blood pressure (OR 0.47, 95% CI 0.29-0.77). CONCLUSION Anaemia control programmes in Uganda should target older people and should include interventions to treat and control hookworms and educational programs on diets that enhance iron absorption. Clinicians should consider screening older people with HIV or malaria for anaemia. Further studies should be done on unexplained anaemia and serum ferritin levels that predict iron deficiency anaemia in older people.

Abstract
This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living) and IADL (instrumental activities of daily living). Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

Abstract
This review provides the clinician with a summary of the causes, implications and potential treatments for the management of anaemia in the older surgical patient. The prevalence of anaemia increases with age and is frequently identified in older surgical patients. Anaemia is associated with increased postoperative morbidity and mortality. Allogenic blood transfusion is commonly used to treat anaemia but involves inherent risks and may worsen outcomes. Various strategies for the correction of pre- and postoperative anaemia have evolved. These include correction of nutritional deficiencies and the use of intravenous iron and erythropoesis stimulating therapy. Clear differences exist between the elective and emergency surgical populations and the translation of research findings into these individual clinical settings requires more work. This should lead to a standardized approach to the management of this frequently encountered clinical scenario.

Abstract
Considering the scarcity of data on the relationship between hemoglobin, serum retinol and habitual meat consumption in the elderly, a cross-sectional population-based study was performed, which was representative of the population of a state capital in Northeastern Brazil, including 176 elderly aged between 60 and 90 years, who responded to questionnaires about habitual food consumption and socioeconomic aspects. Blood counts and serum retinol analyses were carried out. The prevalence of anemia was 9.58%, and 96% of elderly showing adequate serum retinol levels. The consumption of vitamin A and iron was adequate in 93.75% and 85%, respectively. There was no correlation between serum retinol and hemoglobin values (p=0.56), and as expected, there was a positive association between meat consumption and hemoglobin (p=0.02). Based on results obtained in this study, it was concluded that the maintenance of adequate vitamin A and meat intake in this population should be encouraged, which appears to be an effective intervention strategy to achieve appropriate serum retinol and hemoglobin values, and hence lower iron deficiency anemia rates.

Abstract
This study aimed to investigate the association between vitamin D deficiency and anemia in a hospitalized geriatric population. An observational study, at the acute care geriatric unit of Brest Hospital, France, was conducted among 226 patients aged ≥70 years consecutively hospitalized between January 22, 2010 and August 9, 2010. Vitamin D and hemoglobin levels were measured. Vitamin D deficiency was defined as a 25(OH)D level <50 nmol/L and anemia as defined by the World Health Organization. After adjustment for albuminemia, anemia was not significantly associated with vitamin D deficiency (odds ratio (OR) = 1.37; 95 % confidence interval (CI) = 0.72-2.6). But anemia was significantly associated with hypoalbuminemia (OR = 2.08; 95 % CI = 1.11-3.91). Denutrition reflected by hypoalbuminemia could be a possible confounding factor in the previously described association between anemia and vitamin D deficiency.

Abstract
Purpose Falls are common among nursing home residents and have potentially severe consequences, including fracture and other trauma. Recent evidence suggests anemia may be independently related to these falls. This study explores the relationship between the use of anemia-related pharmacotherapies and falls among nursing home residents. Methods Forty nursing homes in the United States provided data for analysis. All incidents of falls over the 6-month post-index follow-up period were used to identify the outcomes of falls (≥1 fall) and recurrent falls (>1 fall). Logistic regression was used to analyze the relationship between falls and recurrent falls with each of the anemia pharmacotherapies after adjusting for potential confounders. Results A total of 632 residents were eligible for analysis. More than half (57%) of residents were identified as anemic (hemoglobin < 12 g/dL females, or <13 g/dL males). Of anemic residents, 50% had been treated with one or more therapies (14% used vitamin B12, 10% folic acid, 38% iron, 0.3% darbepoetin alfa [DARB], and 1.3% epoetin alfa [EPO]). Rates of falls/ recurrent falls were 33%/18% for those receiving vitamin B12, 40%/16% for folic acid, 27%/14% for iron, 38%/8% for DARB, 18%/2% for EPO, and 22%/11% for those receiving no therapy. In the adjusted models, use of EPO or DARB was associated with significantly lower odds of recurrent falls (odds ratio = 0.06; P = 0.001). Other significant covariates included psychoactive medication use, age 75–84 years, age 85+ years, worsened balance score, and chronic kidney disease (P < 0.05 for all). Conclusion Only half of the anemic residents were found to be using anemia therapy (vitamin B12, folic acid, or iron). There is little evidence to support an association between the use of vitamin B12, folic acid, or iron in reducing the rates of falls and recurrent falls in nursing homes. Reduced odds of recurrent falls were observed for DARB or EPO users.

Abstract
AIM There is little data regarding the prevalence and associated comorbidities of anemia in Chinese nursing home older adults. The objective of this study was to investigate the prevalence and associated comorbidities of anemia in Chinese nursing home older adults. METHODS We carried out a retrospective cross-sectional study in nine nursing homes in Hong Kong. The hemoglobin (Hb) level, mean corpuscular volume (MCV), serum creatinine and comorbidities data of residents were examined. Older adults were regarded as anemic according to the World Health Organization criteria (Hb <13 g/dL for men and <12 g/dL for women). The glomerular filtration rate (eGFR) was estimated by the Modification of Diet in Renal Disease Study (MDRD [Chinese-adjusted]) equation. Patients with chronic renal impairment were defined as having eGFR <60 mL/min/1.73 m(2) . RESULTS A total of 812 residents were included (mean age 86.0 ± 7.6 years). The mean hemoglobin was 12.0 ± 1.8 g/dL in men and 11.4 ± 1.6g/dL in women. The mean eGFR was 75.1 ± 31.7 mL/min/1.73 m(2) . A total of 67.0% of residents had anemia (70.5% in men and 65.2% in women). Anemic older adults were older and had a higher prevalence of renal impairment than non-anemic older adults (P<0.001). There was no significant difference between the two groups regarding the prevalence of other comorbidities. When stratified into different age groups, there were significant correlations between anemia and renal impairment in all subgroups (age ≤ 80 years, P<0.05; age 81-90 years, P<0.01; age >90 years, P<0.05). The same correlation was found between normocytic anemia and renal impairment. Conversely, when stratified according to eGFR (≥ 60 mL/min/1.73 m(2) vs <60 mL/min/1.73 m(2) ), we did not observe a significant correlation between anemia and age group. CONCLUSION In conclusion, anemia is prevalent in Chinese nursing home residents and is strongly associated with renal impairment. Further studies of early identification and management of anemia with renal impairment are recommended in this population.

Abstract
BACKGROUND in older persons, anaemia is associated with a number of unfavourable outcomes. In approximately 30% of older persons with anaemia, the cause of the anaemia is unexplained. We assessed the clinical differences between subjects with explained and unexplained anaemia and investigated whether these subjects have different mortality patterns compared with subjects without anaemia. DESIGN observational prospective follow-up study. SETTING the Leiden 85-plus study. PARTICIPANTS four hundred and ninety-one persons aged 86 years. METHODS the study population was divided in three groups: (i) no anaemia (reference group, n=377), (ii) explained anaemia (iron deficiency, folate deficiency, vitamin B12 deficiency, signs of myelodysplastic syndrome or renal failure, n=74) and (iii) unexplained anaemia, (n=40). Mortality risks were estimated with Cox-proportional hazard models. RESULTS haemoglobin levels were significantly lower in subjects with explained anaemia than in subjects with unexplained anaemia (P<0.01). An increased risk for mortality was observed in subjects with explained anaemia [HR: 1.93 (95% CI: 1.47-2.52), P<0.001], but not in subjects with unexplained anaemia [HR: 1.19 (95% CI: 0.85-1.69), P=0.31]. Adjusted analyses (sex, co-morbidity, MMSE, institutionalised and smoking) did not change the observed associations for both explained and unexplained anaemic subjects. CONCLUSION older subjects with unexplained anaemia had similar survival compared with non-anaemic subjects. Increased mortality risks were observed in subjects with explained anaemia compared with non-anaemic subjects.

Abstract
Epidemiologic studies have documented an increasing frequency of anaemia in individuals 65 yrs and older. Elderly individuals with anaemia have been categorised into the following: those with chronic disease, those with iron, B12 or folate deficiency and those with anaemia of unknown aetiology (AUE). There is considerable interest and debate as to whether AUE has an inflammatory component, is caused by cytokine dysregulation affecting production or response to erythropoietin (EPO) or iron availability or represents a novel pathologic process. Here, we compare a large cohort of AUE cases with a matched, non-anaemic control group and with individuals who have anaemia of defined cause. IL-6, hepcidin, GDF15, EPO and testosterone levels were compared. IL6 and hepcidin levels did not differ significantly between AUE and control groups, indicating that inflammation or iron restriction is not central feature of anaemia in this group. GDF15 levels were significantly elevated when comparing AUE with controls and were markedly elevated in patients with renal disease. Testosterone levels were lower in men from the AUE group compared with non-anaemic controls. EPO levels in the AUE group were increased relative to controls but were inappropriately low for the degree of anaemia. Our data indicate that an impaired EPO response, in the absence of evidence for iron restriction or inflammation, is characteristic of AUE.

Abstract
BACKGROUND Anemia has been associated with increased physical and financial costs and occurs more frequently in older individuals. Therefore, the primary objectives of this study were to examine the prevalence and possible predictors of anemia in the very old. METHODS Hemoglobin was used to identify those with anemia in a group of centenarians and near centenarians (98+, n = 185) and octogenarians (n = 69), who were recruited as part of the population-based multidisciplinary Georgia Centenarian Study. Blood markers, including ferritin, vitamin B12, red blood cell folate, methylmalonic acid, creatinine, and C-reactive protein, demographic variables, and medication and/or supplement usage were used to determine possible predictors of anemia. RESULTS The prevalence of anemia was 26.2% in octogenarians and 52.1% in centenarians. Low serum albumin (<3.6 g/dL) and decreased estimated glomerular filtration rate (<45 mL/min/m(2)) were predictors of anemia in centenarians. CONCLUSIONS Anemia is a major health issue, particularly as people age. Because of the high prevalence of anemia in older individuals, awareness of the predictors associated with anemia becomes increasingly important so as to reduce the negative consequences associated with it and allow for the identification of steps that can be taken to correct anemia, including managing chronic disease.

Abstract
BACKGROUND To accurately determine the causes of anemia and proportion of unexplained anemia in a racially diverse cohort of older adults after a comprehensive and standardized evaluation. METHODS We evaluated results from a single-institutional university anemia clinic. Patients with anemia, defined as a hemoglobin less than 13.0 g/dL for men and less than 12.0 g/dL for women, underwent a prospective standardized history, physical examination, and laboratory measures, with additional studies including bone marrow examination as indicated. Empiric treatment trials were given for identified deficiencies. RESULTS One hundred and seventy-four primarily community-dwelling adults aged 65 years and older were evaluable. African Americans accounted for 69% of patients and whites were 27%. Anemia etiologies included iron deficiency anemia at 25.3%, anemia of chronic inflammation at 9.8%, and hematologic malignancy in 7.5%. Unexplained anemia in the elderly accounted for 43.7% and predominated in both African Americans and whites. The prevalence of iron deficiency anemia and hematologic malignancies did not differ by race. Unexplained anemia in the elderly showed a consistent phenotype composed of a hypoproliferative mild-to-moderate anemia with suppressed serum erythropoietin. Specifically, erythropoietin levels showed no correlation with hemoglobin concentration in unexplained anemia in the elderly (r = -.15, p = .19) as opposed to iron deficiency anemia (r = -.63, p < .0001). CONCLUSIONS In summary, an intensive hematologic evaluation reveals a wide number of anemia etiologies among older adults, including 7.5% with hematologic malignancies; nevertheless, unexplained anemia in the elderly prevails as the most common category in whites and African Americans.

Abstract
Introduction: We aim to investigate the prevalence and risk factors for anaemia among the elderly in a tertiary hospital. Methods: A retrospective study was conducted on 742 consecutive geriatric patients who were admitted to the medical unit of our hospital. The demographic and laboratory values for patients were examined. Anaemia-related data were studied. Patients with no/missing demographical or laboratory data and those who passed away after admission were excluded. Results: There was a high prevalence of anaemia in the study population. Although there were a significant proportion of nutritional causes, non-nutritional causes formed the majority. Significant risk adjusted risk factors associated with anaemia are male gender, Charlson's co-morbidity index and abnormal serum creatinine levels ≤60ml/min. (OR=1.469 [1.177–1.833], p=0.001; OR=1.147 [1.107–1.189], p<0.001; OR=1.335 [1.064–1.675], p=0.013 respectively.) Contributory factors for sub-types of anaemia were further investigated. A non-Chinese ethnicity, NSAID and anti-platelet use were significant risk factors for iron deficiency anaemia. (OR=2.035 [1.207–3.432], p=0.008; OR=8.202 [3.628–18.540], p<0.001; OR=2.080 [1.260–3.435], p=0.004 respectively.) For B12 deficiency, significant risk factors were non-Chinese ethnicity and metformin use. (OR=1.869 [1.036–3.370], p=0.038; OR=3.314 [1.690–6.499], p<0.001 respectively) A high Charleson's co-morbidity score and male gender correlated with anaemia of chronic disease. (OR=1.192 [1.104–1.288], p<0.001; OR=2.030 [1.198–3.440], p=0.009 respectively.) For anaemia of chronic renal disease, no significant predictors were found. Conclusion: Anaemia remains prevalent in the hospitalised geriatric population. Specific risk factors may help in the diagnosis and management of sub-types of anaemia.

Abstract
The hepatic peptide hormone hepcidin is the principal regulator of iron absorption and its tissue distribution. Pathologically increased hepcidin concentrations cause or contribute to iron-restrictive anemias including anemias associated with inflammation, chronic kidney disease and some cancers. Hepcidin deficiency results in iron overload in hereditary hemochromatosis and ineffective erythropoiesis. The hepcidin-ferroportin axis is the principal regulator of extracellular iron homeostasis in health and disease, and is a promising target for the diagnosis and treatment of iron disorders and anemias.

Abstract
BACKGROUND Nutrient-related anemia among postmenopausal women is preventable; recent data on prevalence are limited. OBJECTIVE To investigate the association between nutrient intakes and anemia prevalence, in relation to both incidence and persistence, in a longitudinal sample of postmenopausal women. We hypothesized that anemia prevalence, incidence, and persistence would be greater among women reporting lower intake of vitamin B-12, folate, and iron. DESIGN Prospective cohort analysis. PARTICIPANTS/SETTING The observational cohort of the Women's Health Initiative, including 93,676 postmenopausal women, aged 50 to 79 years, who were recruited across the United States at 40 clinical study sites. Women were enrolled between 1993 and 1998; data collection for these analyses continued through 2000. MAIN OUTCOME MEASURES Anemia was defined as a blood hemoglobin concentration of <12.0 g/dL (120.0 g/L). Persistent anemia was defined as anemia present at each measurement time point. Diet was assessed by food frequency questionnaire for iron, folate, B-12, red meat, and cold breakfast cereal; inadequacies were based on dietary reference intakes for women older than age 50 years. STATISTICAL ANALYSIS Descriptive statistics (mean ± standard deviation) were used to characterize the population demographics, anemia rates, and diet. Unconditional logistic regression was used to investigate associations between diet and incident and persistent anemia. Associations are presented as odds ratio and 95% confidence intervals. RESULTS Anemia was identified in 3,979 (5.5%) of the cohort. Inadequate intakes of multiple anemia-associated nutrients were less frequent in non-Hispanic whites (7.4%) than other race/ethnic groups (inadequacies demonstrated in 14.6% to 16.3% of the sample). Age, body mass index, and smoking were associated with anemia. Women with anemia reported lower intakes of energy, protein, folate, vitamin B-12, iron, vitamin C, and red meat. Multiple (more than a single nutrient) dietary deficiencies were associated with a 21% greater risk of persistent anemia (odds ratio 1.21, 95% confidence interval 1.05 to 1.41) and three deficiencies resulted in a 44% increase in risk for persistent anemia (odds ratio 1.44, 95% confidence interval 1.20 to 1.73). CONCLUSIONS Inadequate nutrient intake, a modifiable condition, is associated with greater risk for anemia in postmenopausal women participating in the Observational Study of the Women's Health Initiative. Efforts to identify and update incidence estimates for anemia-associated nutrient deficiencies in aging women should be undertaken.

Abstract
OBJECTIVES Aims of the study were to investigate iron status in institutionalized elderly subjects and to determine its association with different factors including: age, gender, body mass index, dietary intake, consumption of iron supplements, functional status and disease. DESIGN A cross-sectional study. SETTING Seven public nursing homes. PARTICIPANTS 252 subjects, aged 65-96 years. MEASUREMENTS Food intake was assessed by a 4-day weighed-food record. Iron status indices were measured. Barthel' s Index was used to evaluate functional status. Illnesses were ascertained from medical records. RESULTS Anemia was found in 25.4% of subjects studied. Average dietary intakes fulfilled the amounts of Recommended Dietary Intake for Spanish elderly population, except for folate. A substantial percentage of subjects exhibited folate dietary deficit (89.2%). Mean (SD) BMI was 27.8 (6.4) kg/m2, and functional status 78.1 (26.5). Taking into account hematocrit, red blood cell count and serum iron concentration values, poor iron status was significantly more common in men (59.4, 61.4 and 16.8%, respectively) than in women (36.4, 36.4 and 6.0%, respectively). Hemoglobin concentration was positively associated with the energy and nutrient dietary intake, and negatively with age, BMI and functional status. CONCLUSIONS Based on World Health Organization criteria, anemia was found in 25.4% of elderly subjects studied. Iron deficiency seems to be the main cause of anemia, and chronic disease the second cause of anemia. Dietary intake is not one of the principal causes of anemia in the study population, except for folate intake.

Abstract
Anemia is a significant problem in elderly patients. Although many anemic elderly patients can be diagnosed with nutritional deficiency, anemia of chronic inflammation or comorbid diseases that explain their decreased hematocrit, the etiology of anemia in a significant fraction remains obscure. There is evidence to suggest that the hematopoietic stem cell displays increasing erythropoietin (EPO) resistance with age. EPO levels rise in elderly, nonanemic patients, and it is hypothesized that there is an interplay between this rising demand for EPO and the decreasing ability of the aging kidney to produce adequate hormone to meet that need. There is further considerable evidence that aging is associated with increased proinflammatory cytokine expression and that many of these cytokines can contribute to EPO insensitivity. Consequently, genetic variation in the expression of these proinflammatory cytokines may influence the development of anemia in elderly patients, both through induction of hepcidin expression (anemia of inflammation) and through cytokine suppression of erythroid colony formation. The impact of inflammatory mediators, EPO insensitivity, and other factors that may act on the hematopoietic stem cell to decrease erythropoiesis are under active study and should serve to elucidate the pathophysiology of this important cause of morbidity and mortality in elderly individuals. A better understanding of the pathophysiology of anemia in elderly patients should provide critical entry points for interventions that will improve survival and quality of life in the aging population.

Abstract
Anaemia is highly prevalent in elderly populations, particularly in long term care facilities and geriatric wards. Even mild anaemia is associated with adverse health outcomes. Although senescence is considered to be a contributing factor, underlying pathology always has to be thoroughly explored. The most frequent etiologies of anaemia in the elderly are anaemia of chronic disease/inflammation; iron, folate and cobalamin deficiency; and myelodysplastic syndrome. Multiple concomitant etiologies are frequently present. The diagnostic workup is straightforward, not very invasive and should be done systematically. Nutrient deficiencies require complete workup and cure. Anaemia of chronic disease/inflammation ideally is taken care of by treating the underlying disease. If this is not possible and if glomerular filtration rate is significantly decreased, treatment with erythropoietin should be considered. Most cases of myelodysplastic syndrome will benefit from supportive care, but a specific subgroup responds particularly well to oral thalidomide analogues. Transfusions should be avoided.

Abstract
The aim of this review is to present age-related changes in the bone marrow and thymus and their effects in later life. Age-related hematologic changes are marked by a decline in marrow cellularity, increased risk of myeloproliferative disorders and anemia, and a decline in adaptive immunity. The exact mechanisms that produce these changes remain undefined. For the most part, the changes in function that are a consequence of aging alone rarely have meaningful clinical consequences. However, in the face of the stresses induced by other illnesses, the decreased physiologic reserve can slow or prevent an appropriate response to the stressors.

Abstract
The occurrence of anemia in older adults has been associated with adverse outcomes including functional decline, disability, morbidity, and mortality. It is not clear to what extent these outcomes are the result of the anemia or concurrent illness. We performed a cross-sectional, observational study to determine whether lower hemoglobin concentrations in older adults are associated with reduced health-related quality of life, functional status, depression, disability, and physical strength, independent of chronic disease. Three sites participated in this research: an academic geriatric practice, a hospital-based geriatric outpatient unit, and a community-based multispecialty internal medicine group. Health-related quality of life and functional status were measured using the Short Form-36 Health Survey (SF-36) and the Functional Assessment of Chronic Illness Therapy-Anemia (FACIT-An). Disability and depression were assessed using the Instrumental Activities of Daily Living (IADL) and the Geriatric Depression Scale (GDS) questionnaires, respectively. Handgrip strength was used as a physical performance measure. Anemia was defined as hemoglobin <13 g/dL for men or <12 g/dL for women. The mean SF-36 physical health component summary scores were 38.9 (with anemia) and 44.1 (without anemia) (p<0.001). Anemia was associated with greater fatigue (p < 0.001), lower handgrip strength (p = 0.014), increased number of disabilities (p=0.005), and more depressive symptoms (p = 0.002). Multivariate regression analysis, adjusted for demographic and clinical characteristics, demonstrated strong associations for reduced hemoglobin, even within the "normal" range, and poorer health-related quality of life across multiple domains. Thus, anemia was independently associated with clinically significant impairments in multiple domains of health-related quality of life, especially in measures of functional limitation. Mildly low hemoglobin levels, even when above the World Health Organization (WHO) anemia threshold, were associated with significant declines in quality of life among the elderly.

Abstract
Anemia is a common, multifactorial condition among older adults. The World Health Organization (WHO) definition of anemia (hemoglobin concentration <12 g/dL in women and <13 g/dL in men) is most often used in epidemiologic studies of older adults. More than 10% of community-dwelling adults age 65 years and older has WHO-defined anemia. After age 50 years, prevalence of anemia increases with advancing age and exceeds 20% in those 85 years and older. In nursing homes, anemia is present in 48% to 63% of residents. Incidence of anemia in older adults is not well characterized. Among older adults with anemia, approximately one third have evidence of iron, folate, and/or vitamin B(12) deficiency, another third have renal insufficiency and/or chronic inflammation, and the remaining third have anemia that is unexplained. Several studies demonstrate that anemia is associated with poorer survival in older adults. This review details the distribution and consequences of anemia in older adults and identifies future epidemiologic research needs.

Abstract
Nutritional anemias are important because they are easily reversed and because their underlying causes, most often unrelated to dietary intake, require individualized assessment. Iron-deficiency anemia (IDA) usually results from iron losses accompanying chronic bleeding, including loss to intestinal parasites, or from gastric disorders or malabsorption in the elderly. Cobalamin-deficiency anemia, the only nutritional anemia with predilection for the elderly, nearly always stems from failure of intrinsic factor (IF)-related absorption. Folate-deficiency anemia, the only nutritional anemia usually caused by poor intake, has nearly disappeared in countries that fortify food with folic acid. Copper-deficiency anemia, which usually results from malabsorptive disorders or from medical or nutritional interventions that provide inadequate copper or excess zinc, is uncommon but increasingly recognized. The prevalences of nutritional anemias, which are not always distinguished from non-anemic deficiency, are uncertain. The mean corpuscular volume (MCV) provides an essential diagnostic tool leading to judicious matching of relevant biochemical changes with relevant anemia. Nutritional anemias usually feature abnormal MCV, whereas the predominant anemias in the aged, especially the anemias of chronic disease/chronic inflammation (ACD/ACI), of renal failure, and of unknown causes, are typically normocytic.

Abstract
Among the elderly, anemia occurs with increasing frequency with each advancing decade. Unlike when anemia occurs in younger adults, the cause of anemia in the elderly is oftentimes not readily apparent or attributable to a single cause. However, this commonly observed form of anemia in the elderly (termed unexplained anemia [UA]) can generally be dissected to its root causes, which include renal insufficiency, inflammation, testosterone deficiency, and stem cell proliferative decline. Myelodysplasia (MDS) occurs commonly in this age group but can and should, for both diagnostic and therapeutic considerations, be distinguished from UA.
