Proactive Psychiatry: Innovating the Delivery of Consultation-Liaison Services in a Pediatric Hospital.

Background: The benefits of a proactive consultation-liaison psychiatry service have been well documented in the adult population, including decreased length of stay (LOS), increased satisfaction among physicians, and enhanced collaborative care. However, there is no available research on the effectiveness of this model in pediatric hospitals.

Objective: This study compared patients aged 5-18 years on a general medical floor receiving a proactive psychiatry consult to concurrent controls receiving no consult and to historical controls receiving traditional reactive consults.

The Gut Microbiome Modulates Body Temperature Both in Sepsis and Health.

Among patients with sepsis, variation in temperature trajectories predicts clinical outcomes. In healthy individuals, normal body temperature is variable and has decreased consistently since the 1860s. The biologic underpinnings of this temperature variation in disease and health are unknown.

Antibiotics cause metabolic changes in mice primarily through microbiome modulation rather than behavioral changes.

Background: The microbiome is an important and increasingly-studied mediator of organismal metabolism, although how the microbiome affects metabolism remains incompletely understood. Many investigators use antibiotics to experimentally perturb the microbiome. However, antibiotics have poorly understood yet profound off-target effects on behavior and diet, including food and water aversion, that can confound experiments and limit their applicability.

Variation in coding (NADH dehydrogenase subunits 2, 3, and 6) and noncoding intergenic spacer regions of the mitochondrial genome in Octocorallia (Cnidaria: Anthozoa).

Low rates of evolution in cnidarian mitochondrial genes such as COI and 16S rDNA have hindered molecular systematic studies in this important invertebrate group. We sequenced fragments of 3 mitochondrial protein-coding genes (NADH dehydrogenase subunits ND2, ND3 and ND6) as well as the COI-COII intergenic spacer, the longest noncoding region found in the octocoral mitochondrial genome, to determine if any of these regions contain levels of variation sufficient for reconstruction of phylogenetic relationships among genera of the anthozoan subclass Octocorallia. Within and between the soft coral families Alcyoniidae and Xeniidae, sequence divergence in the genes ND2 (539 bp), ND3 (102 bp), and ND6 (444 bp) ranged from 0.
