Activist Manipulation Dynamics

Two activists with correlated private positions in a firm's stock trade sequentially before simultaneously exerting effort that determines the firm's value. We document the existence of a novel linear equilibrium in which an activist's trades have positive sensitivity to her block size, but such orders are not zero on average: the leader activist manipulates the price to induce the follower to acquire a larger position and thus add more value. We examine the implications of this equilibrium for market outcomes and discuss its connection with the prominent phenomenon of \wolf-pack" activism: multiple hedge funds engaging in parallel with a target firm. We also explore the possibility of other equilibria where the activists trade against their initial positions

The value of admission glycosylated hemoglobin level in patients with acute myocardial infarction

Background: Glycosylated hemoglobin (HbA1c) level on admission is a prognostic factor for mortality in patients with and without diabetes after myocardial infarction. In the present study, the authors examined the relationship between admission HbA1c level and myocardial perfusion abnormalities in patients with acute myocardial infarction. Methods: One hundred consecutive patients with acute myocardial infarction who were treated with thrombolytic therapy were included in the present prospective study. Blood glucose and HbA1c levels of all patients were measured within 3 h of admission. Patients were divided into three groups according to HbA1c level: 4.5% to 6.4% (n=25), 6.5% to 8.5% (n=28) and higher than 8.5% (n=47). All patients then underwent exercise thallium-201 imaging and coronary angiography to determine ischemic scores and the number of diseased coronary arteries four weeks after admission. Results: Seven patients died within the four-week follow-up period. There was a significant relationship between admission HbA1c level and mortality (P=0.009). Furthermore, there was a significant relationship between HbA1c level and total ischemic scores in patients with acute myocardial infarction (r=0.482; P=0.001). Ischemic scores increased as HbA1c levels increased in patients with acute myocardial infarction. Conclusions: The results demonstrated that admission plasma glucose and HbA1c levels are prognostic factors associated with mortality after acute myocardial infarction. ©2008 Pulsus Group Inc.

Abdominal aortic aneurysm surgery: retroperitoneal or transperitoneal approach?

Aim. Mortality and morbidity of abdominal aortic aneurysm surgery have decreased significantly in time and transperitoneal approach (TPA) stiff preserves its popularity although retroperitoneal approach (RPA) is known to cause lower incidence and shortened duration of ileus, shorter intensive care unit (ICU) and hospital stay, earlier oral intake and less patient discomfort or pain

Candida albicans endocarditis and a review of fungal endocarditis: Case report

Endocarditis due to fungal etiology is rare, but it is the most severe form of infective endocarditis. Fungal endocarditis is commonly complicated by systemic embolizations, and the difficulty in isolating the fungi with routine blood cultures complicates the diagnostic process. In these culture-negative cases of endocarditis, etiologic diagnosis is made with histopathologic examination of the cardiac valve, embolic materials, and systemic ulcers. In this case report, the presented patient with fungal endocarditis and its neurologic complications was treated with a surgical and medical approach

Is routine intravascular shunting necessary for carotid endarterectomy in patients with contralateral occlusion? A review of 5-year experience of carotid endarterectomy with local anaesthesia

Objectives. Endarterectomy of a stenotic internal carotid artery in the presence of contralateral carotid occlusion (CCO) is Often assessed as a high-risk procedure. We have assessed the requirementfor shunting in patients with CCO operated under local anaesthetic
