作者： Assane Sall Massamba Bâ Pascal Tienin Babou Rokhaya Djajheté Dalahata Bâ Mamadou Coumé geriatrics department Fann/Dakar University Hospital Dakar Senegal

Background/Objective: Anemias are frequent conditions in geriatric practice. The etiologies are numerous, overlapping chronic and acute pathologies. it is also associated with high morbidity and mortality. In our context, few studies have addressed this issue, and none have been carried out in geriatric units with integrated geriatric dimensions. The aim of this study was to describe the particularities of anemia in old people in a geriatric short-stay service in Senegal. Materials and methods: This was a retrospective, descriptive study from 01 May 2019 to 31 December 2021, involving people aged 60 or over, hospitalized in the geriatrics department of Fann Hospital (Senegal) and presenting with anemia. Epidemiological, clinical and evolutionary characteristics were collected and analyzed using SPSS 24.0 software. Results: The prevalence of anemia was 32.3%. The mean age of our sample was 78.7 ± 8.5 years. Arterial high blood pressure (59.3%), diabetes mellitus (22.8%), prostate disease (12.3%) were the most frequent comorbidities. Clinical manifestations were dominated by physical asthenia (80%) and severe alteration of general condition (72%). The geriatric syndromes were essentially represented by the loss of Activities Daily Living (ADL) autonomy (65%), undernutrition (59%) and frailty (46%). The mean hemoglobin level was 8.4 g/dl ± 2.1. The main etiologies were infections (32.7%), chronic kidney disease (20.9%), iron deficiency (7.4%). The mean hospital stay was 8 days ± 3.7 days and the mortality rate was 19%. Conclusion: Anemia is a frequent occurrence in geriatric medicine, with a high morbidity and mortality rate;its expression is often atypical, with frequent geriatric syndromes;the etiologies are multiple and often interrelated, requiring an exhaustive and multidimensional approach.

The Inhibitory Effects of PSS-Loaded Nanoparticles on the Dysfunction of Cardiac Microvascular Endothelia in Rats with Diabetic Cardiomyopathy

Journal of Ocean University of China 2019年第1期18卷 253-259页

作者： AN Nina YU Luyan HU Yi FENG Wenjing SHI Shujuan CHEN Honghua MAO Yongjun department of geriatrics the Affiliated Hospital of Qingdao University

Propylene glycol alginate sodium sulfate-loaded nanoparticles(PSS-NP) has been shown potential to prevent the microvascular endothelial injuries caused by diabetic cardiomyopathy(DCM). In this study, we aimed to investigate the effects of PSS-NP on the dysfunction of cardiac microvascular endothelia in streptozotocin(STZ)-induced DCM rat model. Echocardiographic measurements showed a significant improvement of cardiac function in the PSS-NP-treated group. Our results revealed that the abnormalities of cardiac systolic and diastolic functions were suppressed by the treatments of prostaglandin E1(PGE1), low molecular weight heparin(LMWH), PSS and PSS-NP. Our comparison analysis indicated that PSS-NP showed the strongest inhibitory effects on microvascular endothelial injuries. Transmission electron microscopy analysis demonstrated that PSS-NP protected the cardiac microvascular endothelium and further improved endothelium dysfunction in DCM rats. ELISA and Western blot assays further showed a high efficiency of improving cardiac microvascular endothelial dysfunction with PSS-NP. Our results demonstrated that PSS-NP increased the protein expression of phosphatidylinositol 3-kinase(PI3K)-p85 and vascular endothelial growth factor(VEGF)-A, and the phosphorylation of protein kinase B(Akt) and endothelial nitric oxide synthase(eNOS), which were involved in the amelioration of cardiac microvascular endothelial dysfunction. These data suggest that PSS-NP may be a novel approach to the treatment the coronary microcirculation disorder diseases such as DCM.
