Seasonal variation and diet quality among Spanish people aged over 55 years.

There is evidence supporting the importance of a healthy diet; however, there are few studies analyzing the seasonal variation of food intake. The present study was aimed to evaluate seasonal variation of food and energy intake in Spanish elderly also to investigate diet quality based on the Healthy Eating Index (HEI) score. From a cross-sectional study, 28 individuals (39% males) aged over 55 years volunteered for a longitudinal follow-up.

CD133+ stem cell mobilization after partial hepatectomy depends on resection extent and underlying disease.

Background: Bone marrow stem cells (BMSC) can participate to liver regeneration. However, conflicting results have been reported on this topic in patients undergoing liver resection.

Aims: To assess the impact of liver resection extent and presence of underlying liver disease in modulating BMSC mobilization.

Hereditary thrombocytosis caused by MPLSer505Asn is associated with a high thrombotic risk, splenomegaly and progression to bone marrow fibrosis.

Unlabelled: Background The MPL(Ser505Asn) mutation has been reported to be a cause of hereditary thrombocythemia. Recently, we detected this mutation in a large proportion of children with familial thrombocythemia, suggesting that in Italy the incidence of MPL(Ser505Asn) mutation could be underestimated.

Design And Methods: We extended the search for this mutation to all patients with essential thrombocythemia who had a positive family history for thrombocytosis or essential thrombocythemia.

Synovial B cells of rheumatoid arthritis express ZAP-70 which increases the survival and correlates with the inflammatory and autoimmune phenotype.

B cells have acquired an important role in the pathogenesis of rheumatoid arthritis (RA) since B cell depletion allowed to rescue patients poorly responders to TNFalpha blockers. This study focused on the involvement of ZAP-70 as a bio-marker of B cells immune activation in RA. ZAP-70 expression in synovial fluid (SF) B cells obtained from RA patients was increased compared to SF B cells of osteoarthritis (OA) patients.
