We have reviewed the renormalization procedure used in the unitarized coupled-channel model of Romanets et al. (Phys Rev D 85:114032, 2012), and its impact in the 
, 
, and 
sector, where five 
states have been recently observed by the LHCb Collaboration. The meson-baryon interactions used in the model are consistent with both chiral and heavy-quark spin symmetries, and lead to a successful description of the observed lowest-lying odd parity resonances 
and 
, and 
and 
resonances. We show that some (probably at least three) of the states observed by LHCb will also have odd parity and 
or 
, belonging two of them to the same 
HQSS multiplets as the latter charmed and beauty 
baryons.
