Coagulase-negative staphylococci are now the chief cause of bacteremia in neonatal intensive care units. To investigate potential risk factors for this nosocomial infection, we conducted a case--control study among 882 infants treated in two neonatal intensive care units during 1982. ⋯ The risk of coagulase-negative staphylococcal bacteremia in infants in neonatal intensive care units can be attributed primarily to the intravenous administration of lipid emulsions. Since lipids are critical for the nutritional support of premature infants, further studies are needed to examine the pathogenesis and prevention of lipid-associated bacteremia.

The optimal management of immune thrombocytopenic purpura during pregnancy remains controversial because the risk of severe neonatal thrombocytopenia remains uncertain. We studied the outcome of the index pregnancy in 162 women with a presumptive diagnosis of immune thrombocytopenic purpura to determine the frequency of neonatal thrombocytopenia and to determine whether neonatal risk could be predicted antenatally by history or platelet-antibody testing. ⋯ The absence of a history of immune thrombocytopenic purpura or the presence of negative results on circulating-antibody testing in pregnant women indicates a minimal risk of severe neonatal thrombocytopenia in their offspring.

Randomized Controlled Trial Clinical Trial
The effect of warfarin on mortality and reinfarction after myocardial infarction.
The use of oral anticoagulation in the long-term treatment of survivors of acute myocardial infarction has been highly controversial. We therefore randomly assigned 1214 patients who had recovered from acute myocardial infarction (mean interval from the onset of symptoms to randomization, 27 days) to treatment with warfarin (607 patients) or placebo (607 patients) for an average of 37 months (range, 24 to 63). ⋯ Long-term therapy with warfarin has an important beneficial effect after myocardial infarction and can be recommended in the treatment of patients who survive the acute phase.
