Abstract
Abstract
Anemia is a common finding in the elderly. Approximately 10 percent of the elderly suffers from anemia. Anemia per se is an independent factor of mortality in older patients regardless its cause. Frailty is also frequent in geriatric patients. That means that there is a decreased reserve capacity to react to different stress factors including anemia. The frequent presence of heart failure and also impaired cerebrovascular circulation makes more difficult to tolerate anemia in older age.
Anemia is a symptom, finding and treating the underlying cause is also important.
Treatment always depends on clinical findings: the more severe the symptoms, the more important to treat them. Severity of anemia depends not only the underlying cause, degree of anemia, co-morbidities and frailty of the patients, but also the speed of its development. Sudden blood loss due to an accident is less well tolerated than the same degree of anemia due to B12 deficiency.
Main causes of anemia in the elderly include nutritional deficiencies, chronic diseases, tumors, and certain hematological malignancies such as chronic lymphocytic leukemia, multiple myeloma, myelodysplastic syndrome.

Al-Shamsi S, Al-Bluwi GSM, Al Shamsi M, Al Kaabi N, Al Khemeiri S, Baniyas N. Prognostic impact of anemia on the mortality of United Arab Emirates nationals with cardiovascular disease. Qatar Med J 2022; 2022:3. [PMID: 35321122 PMCID: PMC8928605 DOI: 10.5339/qmj.2022.3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 01/10/2022] [Indexed: 11/24/2022] Open
Abstract
Background: Cardiovascular disease is the leading cause of death worldwide. Multiple risk factors, including low hemoglobin levels, have been associated with poor outcomes in patients with cardiovascular disease. However, the long-term impact of anemia on death has not been investigated in high-risk patients in the United Arab Emirates. Therefore, this study evaluated whether anemia is a significant predictor of mortality in United Arab Emirates nationals with cardiovascular disease over 10 years. Methods: A retrospective cohort study was conducted in an adult population of United Arab Emirates nationals with a history of cardiovascular disease, recruited from a tertiary healthcare facility. Electronic medical records between April 2008 and December 2008 were reviewed, and follow-up was conducted until December 2019. The survival functions for all-cause mortality in the presence and absence of anemia were compared using univariate Kaplan–Meier analysis with a log-rank test. The association between anemia and all-cause mortality was evaluated using a multivariable Cox regression model. Results: A total of 224 patients were included in the follow-up for 10.5 years. At baseline, 46% of the patients had anemia, with a mean Hgb level of 105.5 ± 28.0 g/L. Patients with anemia were older (68 vs. 63 years, p = 0.001) and had a higher rate of chronic kidney disease (37.5% vs. 17.5%, p = 0.001) than those without anemia. A total of 77 (34.4%) deaths were recorded by the end of the follow-up period. Risk of all-cause mortality was significantly higher in patients with anemia than in those without (hazard ratio = 2.03, 95% confidence interval = 1.22–3.40, p = 0.006). Age and chronic kidney disease were also statistically significant predictors of death (p < 0.001 and p = 0.001, respectively). Conclusion: Anemia is an independent predictor of all-cause mortality in United Arab Emirates nationals with underlying cardiovascular disease. Early intervention and treatment for anemia may improve clinical outcomes in this population.

Abstract
BACKGROUND Up to 15% of people aged 60 and over are anemic, and the prevalence of anemia increases with age. In older men and women, anemia is associated with increases in the risk of death and all-cause hospitalization, poor functional capacity, quality of life, and depression. METHODS AND RESULTS We reviewed the literature describing anemia in aging populations, focusing on the specific diagnostic criteria of anemia and potential causes in older men and women. Even after extensive etiologic workup that involves careful medical history, physical examination, laboratory measurements, and additional studies such as bone marrow biopsy, anemia of aging is unexplained in up to 40% of older patients with anemia. As a result, treatment options remain limited. CONCLUSIONS The prevalence of unexplained anemia of aging (UAA; also called unexplained anemia of the elderly, UAE), its deleterious impacts on health, physical function, and quality of life, and the lack of effective treatment or therapy guidelines represent a compelling unmet clinical need. In this review and consensus document, we discuss the scope of the problem, possible causes of UAA, diagnostic criteria, and potential treatment options. Because even mild anemia is strongly linked to poor clinical outcomes, it should receive clinical attention rather than simply being considered a normal part of aging.

Abstract
This study aimed to determine the prevalence of anemia and factors associated with anemia among men in Malaysia. The researchers used data from the 2019 National Health and Morbidity Survey (NHMS). The hemoglobin levels of men aged 15 years and above who gave their consent was measured using the HemoCue® Hb 201+ System©. The majority of them (87.2%) were men aged 15-59 years, referred to as the younger age group in this study. The prevalence of anemia among men was 12.6% (95% confidence interval (CI): 10.9, 14.5). The prevalence was higher among older men (30.7%; 95% CI: 26.6, 35.1) than younger men (10.0%; 95% CI: 8.2, 12.2). Anemia among men was associated with older age (adjusted odds ratios (aOR) = 3.1; 95% CI: 2.1, 4.4) and those with diabetes (aOR = 1.5; 95% CI: 1.2, 2.1) via a logistic regression analysis. In conclusion, older men were more affected by anemia than younger men in this study. Anemia among older men in Malaysia is at the level of moderate to severe public health significance. The likelihood of developing anemia is increased among older men with diabetes compared to older men without diabetes. These often-overlooked issues among men need to be detected and treated early in order to prevent complications and improve their quality of life.

Abstract
Medicinal plants can protect different organs against diabetes-induced oxidative stress due to their antioxidant compounds. The present study was designed to investigate the potential of Allium saralicum R.M. Fritsch (A. saralicum) ethanolic extract to alleviate the adverse effects of streptozotocin (STZ)-induced diabetes in male BALB/c mice. Seventy male mice were randomly divided into seven groups (n = 10). Diabetes was experimentally induced by STZ (60 mg/kg bw). A. saralicum ethanolic extract with doses 5, 20, 80, and 320 mg/kg was administrated for 20 consecutive days in diabetic animals. Based on the obtained results, the untreated diabetic mice showed high blood glucose level, cholesterol, low-density lipoprotein (LDL), white blood cells count (WBC), and platelets, as well as liver enzymes, urea, and creatinine. Administration of different doses of A. saralicum extract significantly reduced blood glucose level similar to glibenclamide. Also, the levels of catalase and superoxide dismutase enzymes restored toward normal level. All hepatic and renal function parameters as well as hematological parameters were improved following treatment with A. saralicum extract particularly at high doses. Histopathological studies showed a decrease in hepatic, renal, and pancreatic damage after treatment with A. saralicum extract. The results of the present work indicate that A. saralicum ethanolic extract can attenuate diabetic hepato-renal, pancreatic, and hematological damages.

Abstract
Introduction One of the plants that has long been considered by humans is Equisetum arvense L. Equisetum arvense L is now recommended for external use to heal wounds and for internal use to relieve urinary tract and prostate disorders. In the current study, the antioxidant, cytotoxicity, and anti-human lung cancer properties of Equisetum arvense were investigated in in vitro conditions. Material and methods Total phenolic content, total flavonoid content, radical scavenging activity, and ferrous ion chelating were assessed to evaluate the antioxidant activity. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was chosen to investigate anticancer activity of the plant extract. Results The plant extract scavenged 2,2-diphenyl-1-picrylhydrazyl (DPPH) as a free radical with an IC50 of 12.3 ±0.7 µg/ml better than positive controls. The plant was also rich in phenolic compounds with an amount of 396.2 ±3.2 mg GAE/g for total phenolic content. In the MTT assay, human colorectal carcinoma (HCT-8 [HRT-18], Ramos.2G6.4C10, HT-29, and HCT 116) and normal cell lines (HUVEC) were used to study the cytotoxicity and anticancer potential of Equisetum arvense L against human colorectal cancer. Conclusions The cell viability of Equisetum arvense L was very low against human colorectal carcinoma cell lines without any cytotoxicity towards the normal (HUVEC) cell line. The best anti-human colorectal carcinoma properties of Equisetum arvense L against the above cell lines were observed in the case of the HT 29 cell line.

Abstract
Introduction The present work describes the green synthesis and characterization and cytotoxicity, antioxidant, and anti-human lung cancer activities of silver nanoparticles containing Curcumae kwangsiensis folium leaf aqueous extract. Material and methods Ag nanoparticles were produced by mixing the AgNO3 solution with aqueous C. kwangsiensis folium leaf extract. Characterization of Ag nanoparticles was done by FE-SEM, FT-IR, TEM, and UV-Vis. FE-SEM and TEM images revealed an average diameter of 15-21 nm for the nanoparticles. MTT assay was used on common human lung cancer cell lines, i.e., lung well-differentiated bronchogenic adenocarcinoma (HLC-1), lung moderately differentiated adenocarcinoma (LC-2/ad), and lung poorly differentiated adenocarcinoma (PC-14) cell lines, to survey the cytotoxicity and anti-human lung cancer effects of Ag nanoparticles. Results They had very low cell viability and high anti-human lung cancer activities dose-dependently against HLC-1, LC-2/ad, and PC-14 cell lines without any cytotoxicity towards the normal cell line (HUVEC). The IC50 values of Ag nanoparticles were 249, 187, and 152 μg/ml against HLC-1, LC-2/ad, and PC-14 cell lines, respectively. The best results of cytotoxicity and anti-human lung cancer properties were seen at the concentration of 1000 μg/ml. Ag nanoparticles inhibited half of the DPPH molecules in the concentration of 135 μg/ml. Maybe significant anti-human lung cancer potentials of Ag nanoparticles synthesized by C. kwangsiensis folium leaf aqueous extract against common human lung cancer cell lines are linked to their antioxidant activities. Conclusions After confirming the above results in the clinical trial research, this formulation can be administered to treat human lung cancers in humans.

Abstract
Diabetes mellitus (DM) and also anemia are common in the elderly and have a negative impact on the clinical outcomes of patients. The coexistence of anemia and DM seems to be insufficiently recognized; therefore, the aim of our study is to analyze the incidence and clinical consequences of this coexistence, including mortality, in the population of people aged ≥60. A retrospective study was conducted on 981 primary care clinic patients aged ≥60 during 2013-2014. The prevalence of coexistence of DM and anemia (defined in accordance with WHO) and data on the incidence of comorbidities, hospitalization, medical procedures, and all-cause mortality were analyzed. In the study population, 25% had DM, while 5.4% had both DM and anemia. Peripheral artery disease (PAD) was found in 48 patients (4.89%) of the entire study population, more often in men (p < 0.001). Diabetic patients with anemia compared to nonanemic diabetics had more comorbidities (median 4 (4, 5) vs. 3 (2-4); p < 0.001)-PAD more often (p = 0.004), more hospitalization (median 2 (0-11) vs. 0 (0-11); p < 0.001), and more frequent medical procedures (e.g., percutaneous coronary intervention (p < 0.001), coronary artery bypass surgery (p = 0.027), arteriography (p < 0.001), and bypass surgery or endovascular treatments of lower limb ischemia (p < 0.001)). The cumulative survival of patients with both DM and anemia vs. nonanemic diabetics at 36 months was 86.4% vs. 99.3% (p < 0.001). A multivariate logistic regression model showed anemia to be a significant risk factor for death in diabetic patients (p = 0.013). Patients with both DM and anemia have more comorbidities than nonanemic diabetic patients; they are more often hospitalized, require medical procedures more frequently, and are at a higher risk of death. Effective treatment of anemia in patients with DM is advisable and may well improve the prognosis of patients.

Abstract
The prevalence of dementia is around 5% worldwide in people above 65 years, which increases with aging. Alzheimer's disease is the most common cause of dementia in the elderly. On the other hand, anemia is considered one of the most prevalent comorbidities in the elderly with a prevalence of 11% in those above the age of 65. It is crucial that we find the association between anemia and dementia, as this linkage can prove beneficial. Many currently conducted studies support the idea that anemia is a significant risk factor for dementia. However, some studies still consider anemia and dementia as just an aging process, nothing more. In our study, we found that there are a lot of theories, such as low brain hemoglobin associated with low oxygen levels, which leads to neuron damage. One article mentioned that it is dependent on the level of hemoglobin as an effect with mild to moderate anemia, but apparent with severe forms of it. Researchers are expected to further explore and identify the exact relationship between anemia and dementia. We used the PubMed database as the principal source for data search and extracted articles exploring the relationship and role of anemia in decreasing the cognitive brain functions in the elderly. We reviewed 35 different articles, including clinical trials, review papers, randomized controlled trials (RCTs), and original research published between 2010 and 2020 to find commonly accepted pathophysiology that highlights how anemia causes a decrease in cognitive brain functions.
