In this paper we provide evidence on the survival and growth of small and medium-sized enterprises (SMEs) in Vietnam relying on three partly overlapping enterprise surveys sampled during the period 1990-2002. Our empirical results indicate that classical determinants of performance including firm age, firm size, location, ownership, degree of capital intensive production and the type of activit...

Human T-lymphotropic virus type I (HTLV-I) provirus load was examined in a cohort of a population in Guinea-Bissau among whom human immunodeficiency virus (HIV) type 2 is endemic. Geometric mean of HIV-2 RNA load among HTLV-I-coinfected subjects was significantly lower than that in subjects infected with HIV-2 alone (212 vs. 724 copies/mL; P=.02). Adjusted for age, sex, and HIV status, the risk...
