Novel hematologic inflammatory parameters to predict acute mesenteric ischemia.
Acute mesenteric ischaemia (AMI) is an emergency condition that requires urgent diagnosis. Neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) have been studied as inflammatory biomarkers in atherosclerosis, but data regarding AMI are lacking. The study population included patients with AMI (n = 46) versus age and sex-matched healthy controls (n = 46). ⋯ NLR level greater than 4.5, measured on admission, yielded an area under the curve value of 0.790 (95% confidence interval 0.681-0.799, sensitivity 77%, specificity 72%), and PLR level of greater than 157 yielded an area under the curve value of 0.604 (95% confidence interval 0.486-0.722, sensitivity 59%, specificity 65%). Patients with AMI had increased NLR, PLR, and CRP levels compared with controls. Increased NLR and PLR was an independent predictor of AMI.

Assessment of rotation thromboelastometry parameters in patients with essential thrombocythemia at diagnosis and after hydroxyurea therapy.
Patients with essential thrombocythemia suffer from thrombotic complications that are the main source of mortality. Due to its complex pathogenesis, no existing single laboratory method is able to identify the patients at highest risk for developing thrombosis. Twenty patients with essential thrombocythemia at diagnosis, 15 healthy volunteers and 20 patients treated with hydroxyurea were compared with regard to certain rotation thromboelastometry parameters. ⋯ Patients on hydroxyurea therapy had markedly lower MCF values according to EXTEM test than patients at diagnosis. Patients with essential thrombocythemia demonstrate a prothrombotic state at the time of diagnosis, which is reflected in changes by certain rotation thromboelastometry parameters. The hydroxyurea therapy induces downregulation of the prothrombotic features seen in essential thrombocythemia patients at diagnosis.
