  We study the mean-field thermodynamics and the characteristics of the
net-baryon number fluctuations at the phase boundaries for the chiral and
deconfinement transitions in the Hybrid Quark-Meson-Nucleon model. The chiral
dynamics is described in the linear sigma model, whereas the quark confinement
is manipulated by a medium-dependent modification of the particle distribution
functions, where an additional scalar field is introduced. At low temperature
and finite baryon density, the model predicts a first-, second-order chiral
phase transition, or a crossover, depending on the expectation value of the
scalar field, and a first-order deconfinement phase transition. We focus on the
influence of the confinement over higher-order cumulants of the net-baryon
number density. We find that whereas the cumulants show a substantial
enhancement around the chiral phase transition, they are not as sensitive to
the deconfinement transition.
