Usefulness of Clinical Data and Biomarkers for the Identification of Frailty After Acute Coronary Syndromes
2015
Abstract Background Frailty predicts mortality after acute coronary syndrome (ACS). The standard frailty scales, such as the Fried score, consist of a variety of questionnaires and physical tests. Our aim was to investigate easily available clinical data and blood markers to predict frailty at discharge, in elderly patients after ACS. Methods A total of 342 patients older than 65 years, survivors after ACS, were included. A high number of clinical variables were collected. In addition, blood markers potentially linked to frailty and related to the processes of inflammation, coagulation, hormonal dysregulation, nutrition, renal dysfunction, and heart dysfunction were determined. Frailty was …
Oxygenation Status of Gynecologic Tumors: What is the Optimal Hemoglobin Level?
2002
Tumor hypoxia has been linked to the development of treatment resistance, tumor progression, and poor prognosis. Since anemia is a major causative factor for the development of hypoxia, the association between blood hemoglobin concentration (cHb) and tumor oxygenation was examined in this study.Pretreatment O(2) tension (pO(2)) measurements were performed in 59 primary carcinomas of the uterine cervix in which a stringent histopathologic examination of the electrode tracks was mandatory in order to exclude measurements in necrotic, stromal or normal cervical tissue. In addition, pO(2) readings in twelve primary cancers and 17 local recurrences of vulvar cancers were included in this study. …
High-speed rotational angioplasty-induced echo contrast in vivo and in vitro optical analysis
1992
High-speed rotational angioplasty is being evaluated as an alternative interventional device for the endovascular treatment of chronic coronary occlusions. It has been postulated that this type of angioplasty device may produce particulate debris or cavitations that induce myocardial ischemia. To determine the clinical presence of myocardial ischemia during rotational angioplasty, echocardiographic monitoring for wall motion abnormalities was performed in 9 patients undergoing rotational atheroablation using the Auth Rotablator for 10-sec intervals at 150,000 and 170,000 rpm. No wall motion abnormalities were detected in 5 patients evaluated with transesophageal echocardiography or in 4 pat…
Exercise Effects on Erythrocyte Deformability in Exercise-induced Arterial Hypoxemia
2014
Exercise-induced arterial hypoxemia (EIAH) is often found in endurance-trained subjects at high exercise intensity. The role of erythrocyte deformability (ED) in EIAH has been scarcely explored. We aimed to explore the role of erythrocyte properties and lactate accumulation in the response of ED in EIAH. ED was determined in 10 sedentary and in 16 trained subjects, both before and after a maximal incremental test, and after recovery, along with mean corpuscular volume (MCV) and red blood cell lactate concentrations. EIAH was found in 6 trained subjects (∆SaO2=-8.25±4.03%). Sedentary and non-EIAH trained subjects showed reduced ED after exercise, while no effect on ED was found in EIAH train…
