BACKGROUND: Effects of aging on hematologic and biochemical variables are well described in people. Anemia of the elderly is attributed to iron deficiency, anemia of chronic disease, chronic kidney disease, myelodysplasia, or idiopathic causes. Limited studies have examined these variables in aging dogs, but they have typically examined single breeds in research settings. OBJECTIVE: The objective of this study was to identify differences in CBC and biochemistry values between adult and aged dogs of many breeds...

INTRODUCTION: Osteoprotegerin (OPG) is a powerful inhibitor of osteoclast activity, and it plays an important role in bone metabolism. In hemodialysis (HD) patients, the relationship between OPG and bone mineral density (BMD) is important, but remains unclear yet. The study objective was to assess the OPG role related to uremic osteoporosis in HD patients. METHODS: This cross-sectional study has been realized on a cohort of 63 chronic HD patients. INCLUSION CRITERIA: elderly prevalent HD patients with an age over 55 years old...

BACKGROUND: Anemia, a highly prevalent disorder in elderly populations, is associated with numerous adverse health outcomes, including increased mortality, impaired functional status and cognitive disorders. Approximately two-thirds of anemia in American elderly is caused by chronic inflammation or is unexplained. A potential contributing factor may include air pollution exposures, which have been shown to increase systemic inflammation and affect erythropoiesis. Few studies, however, have investigated the associations of air pollution on hemoglobin levels and anemia...

Background The efficacy and safety of bevacizumab in elderly patients with non-small cell lung cancer remain controversial. This study focused on both selecting fit elderly patients and overcoming interpatient variability with respect to pharmacodynamics. Methods Elderly (age: ≥70 years) patients with advanced non-squamous non-small cell lung cancer were enrolled. Patients with uncontrolled congestive heart failure and uncontrolled diabetes were excluded. The treatment regimen comprised carboplatin at an area under the curve of 5 mg/ml/min on day 1, paclitaxel at 90 mg/m(2) on days 1 and 8, and bevacizumab at 15 mg/kg on day 1 every 21 days for up to 4 cycles, followed by maintenance bevacizumab...

Purpose Elderly patients with acute myeloid leukemia (AML) have a poor prognosis, and innovative maintenance therapy could improve their outcomes. Androgens, used in the treatment of aplastic anemia, have been reported to block proliferation of and initiate differentiation in AML cells. We report the results of a multicenter, phase III, randomized open-label trial exploring the benefit of adding androgens to maintenance therapy in patients 60 years of age or older. Patients and Methods A total of 330 patients with AML de novo or secondary to chemotherapy or radiotherapy were enrolled in the study...

Anemia in the elderly is a common finding that is associated with a poorer quality of life, worse outcomes, and increased mortality. While this entity is frequently overlooked, there is often an underlying cause that is correctable. Areas covered: In this review, we shed light on the prevalence of anemia in the elderly population, review the most common causes, particularly iron deficiency anemia and anemia of chronic disease, and describe the available treatment modalities. When a clear etiology for the anemia is ruled-out, the term unexplained anemia may be utilized; while still an under-explored field, one of the underlying pathophysiological mechanisms appears to be associated with an age-related inflammatory process...

PURPOSE OF REVIEW: Myelodysplastic syndromes (MDS) are heterogeneous diseases of the hematopoietic stem cell in the elderly. Anemia is the main symptom that mostly correlates with dysplastic erythropoiesis in the bone marrow. We will review the recent advances in understanding the diverse mechanisms of dyserythropoiesis. RECENT FINDINGS: Dyserythropoiesis defined as 10% dysplastic erythroid cells in the bone marrow is found in more than 80% of early MDS. Immature erythroblasts accumulate at the expense of mature erythroblasts due to differentiation arrest and apoptosis...

The management of major orthopedic surgery in the elderly prototypically reflects the perioperative risks of geriatric, often very frail patients reflecting an aging population. To improve outcome, the risks of anesthesia and surgery as well as of patient comorbidities must be thoroughly assessed and balanced using a multidisciplinary approach. Particular risks include cardiopulmonary morbidity, anemia, risk of hemorrhage and the management by anticoagulation, cerebral impairments as well as frailty and limited physiological reserves in general...

Objective: Previous studies have revealed that the red blood cell distribution width (RDW) was associated with long-term prognosis in patients undergoing percutaneous coronary intervention (PCI). However, they did not exclude patients with anemia. This study, thus, investigated the association between RDW and prognosis in non-anemia patients. Methods: A total of 2 732 patients underwent elective PCI from July 2009 to September 2011 were enrolled in the study. These patients were divided into two groups based on their baseline median RDW levels: low RDW group (RDW<12...

Anemia is common in older persons, and often remains unexplained despite a thorough clinical history, physical examination, and focused laboratory testing, including marrow aspiration, biopsy, and karyotyping. The advent of molecular genetic testing panels in hematology clinical practice has complicated the evaluation of older patients with unexplained anemia. While the presence of a somatic mutation provides evidence of clonal hematopoiesis and may support a diagnosis of a hematologic neoplasm such as one of the myelodysplastic syndromes (MDS), with rare exceptions, individual mutations are not strongly associated with one specific diagnosis, nor are they by themselves diagnostic of neoplasia...
