Standardizing Postoperative Handoffs Using the Evidence-Based IPASS Framework Improves Handoff Communication for Postoperative Neurosurgical Patients in the Neuro-Intensive Care Unit

Aims for Improvement Within one year of initiation of the process improvement plan, we wanted to improve: Direct communication of airway and hemodynamic concerns Direct communication of operative events, complications, and perioperative management goals. Attendance at postoperative handoffs Confirmation of information by receiving teams Staff perceptions of handoff efficacy and teamwork

A communal catalogue reveals Earth's multiscale microbial diversity

Our growing awareness of the microbial world's importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth's microbial diversity.Peer reviewe

The acute effects of cocaine on anterior pituitary hormones in ovariectomized rhesus monkeys

Cocaine stimulates a rapid release of gonadotropins in intact rhesus males and females and human males and enhances synthetic luteinizing hormone-releasing hormone (LHRH), stimulated luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This report describes the effects of acute cocaine administration on basal and synthetic LHRH-stimulated anterior pituitary hormones [LH, FSH and prolactin (PRL)] in five ovariectomized female rhesus monkeys. Integrated blood samples were collected every 10 min for 40 min before i.v. administration of cocaine (0.4 or 0.8 mg/kg) or an equal volume of vehicle control solution and for 110 min after cocaine or placebo administration. Synthetic LHRH (100 micrograms i.v.) was administered 10 min after cocaine or placebo-cocaine injection. In contrast to previous observations in rhesus and human males and in early follicular and midluteal phase rhesus females, cocaine did not change basal levels of gonadotropins or PRL in long-term ovariectomized females. LHRH stimulated a significant and sustained increase in LH (P < .01) within 20 min and FSH (P < .05) within 40 min after placebo-cocaine administration. LHRH also stimulated significant increases in LH and FSH after 0.4 and 0.8 mg/kg cocaine administration. Significant increases in LH (P < .05) and FSH (P < .01) were measured 10 min sooner after 0.8 mg/kg cocaine than after placebo-cocaine, but cocaine did not significantly increase the magnitude or duration of LHRH-stimulated increases in gonadotropins in ovariectomized females as it did in follicular phase females. Basal PRL levels (3.6 +/- 0.2 and 5.5 +/- 0.7 ng/ml) did not change after administration of cocaine alone
