The association between morbid obesity and hyperhomocysteinemia (HH) remains controversial and the nature of this relationship needs to be clarified as several metabolic, lipidic, inflammatory and anthropometric alterations that accompany morbid obesity may be involved. In 66 morbidly obese patients, 47 women and 19 men aged 41 ± 12 years and 66(More)
Although there are several studies dealing with erythrocyte deformability (ED) in obese patients, research on this topic in morbidly obese subjects is scarce. In these studies ED seems to be decreased, although the cause remains unknown. A case-control study in 76 morbid obese subjects (23 women and 53 men, aged 44 ± 13 years) and in 79 normal-weight(More)
OBJECTIVE Red blood cell distribution width (RDW) is a hematological parameter that has been studied in several clinical settings and has been found to be related to both anemia and inflammatory status. As obesity is related to increased inflammatory pattern, we aimed to analyze the RDW in this setting. METHODS We determined hematological and inflammatory(More)
The contribution of hemorheological alterations in the prothrombotic condition in patients with metabolic syndrome (MS) remains a question of debate. We aimed to determine the association between MS and hemorheological parameters by means of a case-control study in 61 MS patients and 89 controls without MS. We determined blood viscosity at 230 s(-1)(More)
OBJECTIVE To analyze the requesting patterns for a range of laboratory tests ordered in 2009 from eight laboratories providing services to eight health areas, using appropriate indicators. DESIGN Indicators measured every test request per 1,000 inhabitants, and indicators that measured the number of tests per related test requested by general(More)
OBJECTIVES The aim of the study is to compare the use of PSA testing among general practitioners (GPs). METHODS The number of PSA tests ordered by general practitioners in the years 2008-2009 was examined in a cross-sectional study of nine health districts of Spain. The percentage of PSA ordered to men younger than 50 (PSA<50/PSAtotal) and 40 years(More)
BACKGROUND The pathogenic role of hyperhomocysteinemia in cryptogenic stroke is not well established. We aimed to determine homocysteine levels in patients with cryptogenic stroke considering the possible variables that may act as confounders and analyze the influence of obesity on this association. PATIENTS AND METHODS We conducted a case-control study(More)
It is not well-established whether the alterations that the hemorheological profile undergoes with aging are an effect of concomitant cardiovascular risk factors or are due to age itself. To clarify this issue, we investigated the effect of age on blood rheology in a population of 927 healthy subjects from eastern Spain aged between 16-85 years, divided(More)
Red blood cell distribution width (RDW) has been shown to be associated with disease activity in several inflammatory disorders. However only one study to show this has been conducted in patients with Behçet's disease (BD). The aim of the present study was to analyse the association of RDW with BD and its main complications; i.e.; thrombosis and posterior(More)
PURPOSE To show the number of preanalytical sample errors in seven laboratories attending seven health departments of Valencian Community (Spain). METHODS Cross-sectional study of the number of preanlytical errors in samples obtained in primary care centers. An error is defined as a rejected specimen: any blood or urine sample, which cannot be(More)
