This study has shown a novel increase in both fibrinogen concentration and factor VIII activity in pregnant women with preeclampsia compared with values obtained from women with normal or non-preeclampsia complicated pregnancies, with women with preeclampsia twice as likely to have a raised fibrinogen concentration and increased factor VIII activity. These changes may contribute to the hypercoagulability seen in preeclampsia.

Thrombophilia has recently been reported to be increased in patients with cystic fibrosis (CF). We wanted to determine whether this was applicable to our population with CF and how our patients compared to the previously reported groups. Seventy one pediatric CF patients were assessed for a thrombophilic tendency, using a lupus anticoagulant screen, protein C, protein S, antithrombin assay, and activated protein C resistance (APCR) screen. The incidence of activate protein C resistance (4.2%) was within expected limits for the general population as was the incidence of antithrombin deficiency. However there was a marked increase in the incidence of lupus anticoagulants (18%) and 14% and 19.7% of the patients showed a reduced protein C and protein S, respectively, far in excess of the general population. This increased incidence of thrombophilia was not related to any specific CF phenotype and while perturbed liver function cannot be entirely ruled out, it appeared unlikely to be responsible for all the abnormal coagulation findings. Despite the apparent thrombophilic tendency, no clinically evident thrombotic episodes were noted during the study period. Thrombophilia is of concern because of the increasingly frequent placement of indwelling catheters in CF patients. The precise cause for the thrombophilic tendency in CF patients is unknown at this stage.

Examines the ability of online auctions to adversely affect relationships between suppliers and buyers. Buyers have to consider relationships with their own company, existing suppliers and new suppliers, building trust and being aware of competing objectives. This article considers how an auction changes the dynamics of these relationships, outlines the positives for using auctions but highlights some possible abuses of the system.
