Expanded CURB-65: a new score system predicts severity of community-acquired pneumonia with superior efficiency.

Aim of this study was to develop a new simpler and more effective severity score for community-acquired pneumonia (CAP) patients. A total of 1640 consecutive hospitalized CAP patients in Second Affiliated Hospital of Zhejiang University were included. The effectiveness of different pneumonia severity scores to predict mortality was compared, and the performance of the new score was validated on an external cohort of 1164 patients with pneumonia admitted to a teaching hospital in Italy.

[The effect of proliferation and differentiation of CD8+ T cells on the progression in patients co-infected with HIV and HCV].

Objective: To investigate the effect of proliferation and differentiation of CD8 T cells on the progression in patients co-infected with HIV and HCV.

Methods: To address this issue, the presences of CD57 and CD28 in the surface of CD8+ T-cell were monitored using flow cytometry in 20 patients co-infected with HIV and HCV and 20 patients infected with HCV alone. The proliferation and differentiations of CD8+ T cell were compared hetween patients co-infected with HIV and HCV and ones with HCV infection alone, to clarify the association hetween the function of CU and the progression of disease.
