Current place of vasopressin analogues in the treatment of septic shock
No full textArginine vasopressin and terlipressin increase mean arterial pressure and reduce catecholamine requirements in septic shock patients. Infusing either agent may reduce incidence of new-onset tachyarrhythmias and improve renal function. The recent Vasopressin and Septic Shock Trial did not demonstrate an overall survival benefit of arginine vasopressin infusion (0.03 U/min) compared with norepinephrine (15 microg/min). However, patients with less severe septic shock (ie, < 15 microg/min of norepinephrine) at arginine vasopressin initiation had a lower 28-day mortality rate compared with norepinephrine-only infusion (26.5% vs 35.7%; P = 0.05). An unpublished study comparing terlipressin (1.3 microg/kg/h), arginine vasopressin (0.03 U/min), and norepinephrine (15 microg/min) as first-line vasopressors showed that terlipressin had higher efficacy than arginine vasopressin in reducing catecholamine requirements. Current literature suggests that early infusion of low-dose continuous arginine vasopressin or terlipressin appears superior to a last-resort treatment. However, because no large clinical trials have proven terlipressin's safety in patients with septic shock, arginine vasopressin is preferred until more data are available

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Landiolol for managing atrial fibrillation in intensive care
No full textLandiolol is an injectable ultrashort acting beta-blocker with high beta1 selectivity indicated for heart rate control of atrial fibrillation in the emergency and critical care setting. Accordingly, landiolol is associated with a significantly reduced risk of arterial hypotension and negative inotropic effects. Based on this particular profile along with the clinical experience in Japan for more than a decade landiolol represents a promising agent for the management of elevated heart rate and atrial fibrillation in intensive care patients even with catecholamine requirements. This article provides a review and perspective of landiolol for heart rate control in intensive care patients based on the current literature
