  We present an upgrade of the 3+1 global fit of short-baseline neutrino
oscillation data obtained with the addition of KARMEN and LSND nu_e-Carbon
scattering data. We discuss the implications for the measurements of the
effective neutrino mass in beta-decay and neutrinoless double-beta-decay
experiments. We find respective predicted ranges of about 0.1-0.7 eV and
0.01-0.1 eV.
