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)
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)
Several studies have found an association between hyperuricemia and metabolic syndrome (MS), although there are discrepancies as to which MS components play a pivotal role in this association. We aimed to investigate the association between serum uric acid (SUA) levels and MS in a Mediterranean population (eastern Spain). We performed a case-control study(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)
It is not yet known whether Yasmin involves a higher thrombotic risk compared with other contraceptives. We present a serie of eight new cases of women who developed thrombotic events early after starting on Yasmin who were sent to our Thrombosis and Hemostasis Unit for a thrombophilia work-up in the last five years. Only two of them were heterozygous(More)
There are few studies on haemorheological disturbances in morbidly obese patients. The role played by the metabolic syndrome on the rheological profile of morbidly obese subjects has not yet been established, and it is not clear whether morbidly obese, but "metabolically healthy", show rheological alterations. We aimed to determine the whole rheological(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)
Although several studies have been published regarding rheological behaviour of red blood cells in beta and delta-beta thalassaemia traits, little information about erythrocyte deformability in alpha-thalassaemia carriers is available. We aimed to determine erythrocyte deformability in heterozygous (silent, -α/αα) and homozygous (minor alpha-thalassaemia,(More)
In a recent paper by Wiewiora et al. published in this Journal [7], the authors observed that superobese patients (BMI >50 kg/m2) show erythrocyte rheological differences when compared with morbidly obese patients (BMI >40 kg/m2). In this sense, although they did not observe differences in erythrocyte deformability using the LORCA device, they found a(More)
