* DaVita Inc., formerly Total Renal Care Holdings Inc., said continued improvement in revenue will probably boost its third-quarter earnings before interest, taxes, depreciation and amortization to the range of $72 million to $78 million. Year-ago comparison figures were not immediately available, but in the second quarter, the company reported a net loss of $15.4 million versus a net loss of $22.1 million in the year-earlier period. Torrance-based DaVita, the nation’s No. 2 provider of kidney dialysis services, attributed the results to higher revenue as well as improved billing and collecting operations.
