Inequalities for positive linear maps of positive selfadjoint operators in Hilbert spaces via some recent reverses of Young's inequality are given. Operator and vector inequalities involving the weighted operator geometric mean are also obtained. Reverses of the celebrated Ando's inequality are provided.
