General results are given for the leading high-temperature contributions to all renormalized Careen's functions. The latter are generated by a high-temperature partition function which describes another φ^4 theory in d spatial dimensions with special mass renormalizations. The triviality/nontriviality of the (φ^4)_1+3 theory is discussed briefiy. %~
