Anemia in the Elderly: Epidemiological, Clinical and Etiological Aspects in Internal Medicine at the Point "G" University Hospital

Abstract

Introduction: Anaemia is a condition that is often underestimated and insufficiently treated in the elderly. It is the most common haematological problem in this age group, with 30% of aetiologies remaining unexplained. In our context, few patients benefit from investigation, hence this study to assess the state of anaemia. Methods: We conducted a retrospective study from January 2011 to December 2012 in the internal medicine department of the Point "G" University Hospital. All hospitalised patients aged 65 and over with anaemia according to the WHO definition were included. Results: Among 199 elderly subjects hospitalised during our study period, 95 (47.73%) presented with anemia. The sex ratio was 1.71. The mean age of the patients was 73.39 ± 6.65 years. Weight loss (82.1%), polypnea (56.5%) and dyspnea (21.1%) were the predominant clinical manifestations. The mean haemoglobin level was 8.93 g/dl, with extremes of 3.1 and 12.5 g/dl. Aregenerative normochromic anemia (37.9%) was the most common. Inflammatory anemia was the main cause of anemia in the elderly (58.6%), followed by multifactorial anemia (20.7%), renal failure (6.9%) and unknown causes (6.9%). Conclusion: Anemia is a frequent condition in elderly patients in internal medicine, dominated by inflammatory causes.

Pinalites: Optical Properties and Quantum Magnetism of Heteroanionic A3MO5X2 Compounds

“…As discussed above, the substitution of A and X ions gives rise to anisotropic deformation of the crystal structure (Figure 1c). Therefore, the magnetic anisotropy J′/J also varies from 0.25 in CROC to 0.45 in Ba 3 ReO 5 Br 2 20 (Table 1). The change in magnetic ground state with magnetic anisotropy is also of interest.…”

CMOS-compatible neuromorphic devices for neuromorphic perception and computing: a review

“…This artificial neuron can sense different pressures and convert them into spike trains, while also perceiving temperature through the metal-insulator transition of the material [100]. In addition, Han et al demonstrated a multimodal sensing device capable of simultaneously receiving visual and thermal stimulation signals [101]. Wang et al reported a multi-mode MXene-ZnO memristive device that simulates the unique environmental adaptation behavior of the human eye by combining light sensing and relative humidity sensing [102].…”

Adaptive Neural Activation and Neuromorphic Processing via Drain‐Injection Threshold‐Switching Float Gate Transistor Memory

“…It is worth noting that considering the raised float gate potential by the enhanced charge tunneling tends to further promote source injection, a positive feedback loop in Figure 3c would form and lead to the rapid charging of float gate and steep threshold switching behavior. Though positive feedback transistors had been previously designed for threshold switching by engineering the dopant profile in transistors, [33,34] the present device has a distinct float gate transistor configuration that stores memory states.…”
