The hospital as business. How saving money can help save lives.

As hospitals and clinics merge into integrated delivery networks dependent for patients on health maintenance organizations, it is sometimes hard to remember who's on first. Instead of doctors, nurses, patients and hospitals, the world of health care now contains an alphabet soup of IDNs, HMOs, providers, consumers and payers. The changes extend deeply into the materials management department, where simply bargaining for the best price has been complicated by standardization, capitation, and a host of expense management strategies. Perhaps as a result of this ever-changing identity, most hospitals have yet to fully adopt the style and culture of the businesses they really are. Even purchasing managers, who are closer to the business end of the operation, are caught up in the traditional image. In the following comments, two experts in materials management explore the impact that this ambivalence has on a hospital's relationship with the outside world--including suppliers. Joseph Colonna is corporate vice president of the purchasing program at Shared Services Healthcare, Atlanta. Michael Garvin is an adjunct professor at the University of Iowa, and a researcher in medical supply purchasing practices.

Avian hematozoa from west-central Bolivia.

A total of 641 birds representing 135 species of 25 families from Noel Kempff Mercado National Park in west-central Bolivia was examined for hematozoa; only 33 (5.1%) harbored blood parasites. Microfilariae were the most commonly encountered hematozoans, followed, in numerical sequence, by species of Haemoproteus and Plasmodium; Trypanosoma, Atoxoplasma, and Hepatozoon were seen infrequently. The survey included 13 new host-parasite records, and 58 species of birds were examined for blood parasites for the first time; 43 were parasite-free. The low prevalence of parasitism recorded in this survey is compared to other areas in the Neotropical region and to prevalence of blood parasites in the avifauna of other major land masses.

Binding of a thromboxane A2/prostaglandin H2 receptor antagonist to guinea-pig platelets.

The binding of [125I]9,11-dimethylmethano-11,12-methano-16-(3-iodo-4-hydroxypheny l)-13,14- dihydro-13-aza-15 alpha beta-omega-tetranor-TXA2 [( 125I]PTA-OH), a thromboxane A2/prostaglandin H2 receptor antagonist, to washed guinea-pig platelets was studied. [125I]PTA-OH bound to guinea-pig platelets in a saturable and displaceable manner. The Kd for [125I]PTA-OH was 14.5 +/- 2 nM (n = 4) and the Bmax was 32 +/- 7 fmol/10(7) platelets or 1,927 +/- 422 binding sites/platelet. The IC50 value for a series of 13-azapinane TXA2 analogs to antagonize the TXA2/PGH2 mimetic U46619-induced platelet aggregation and displace [125I]PTA-OH from its binding site was determined. The IC50 values for the series of five antagonists were highly correlated (r = 0.99) in the binding assays and aggregation studies. The ability of a series of five agonists to displace [125I]PTA-OH from its binding site was compared to their ability to induce platelet aggregation. All the agonists completely displaced the ligand from its binding site but their rank order did not correlate well with their ability to induce aggregation (r = 0.37). Collectively, the data are consistent with the notion that [125I]PTA-OH binds to a putative TXA2/PGH2 receptor in guinea-pig platelets.
