The impact of a web-based prognostic calculator on prognostic confidence in outpatient palliative care.

Purpose: Clinicians are often uncertain about their prognostic estimates, which may impede prognostic communication and clinical decision-making. We assessed the impact of a web-based prognostic calculator on physicians' prognostic confidence.

Methods: In this prospective study, palliative care physicians estimated the prognosis of patients with advanced cancer in an outpatient clinic using the temporal, surprise, and probabilistic approaches for 6 m, 3 m, 2 m, 1 m, 2 w, 1 w, and 3 d.

Predictive Biomarkers of Dyspnea Response to Dexamethasone and Placebo in Cancer Patients.

Context: In the Alleviating Breathlessness in Cancer Patients with Dexamethasone (ABCD) trial, dexamethasone did not improve dyspnea more than placebo in unselected cancer patients. However, it is unclear if patients with greater inflammation would be more likely to derive a treatment response.

Objectives: To examine the predictive utility of cytokines for dyspnea response.

Functional redundancy in local spatial scale microbial communities suggests stochastic processes at an urban wilderness preserve in Austin, TX, USA.

Empirical evidence supports selection of soil microbial communities by edaphic properties across large spatial scales; however, less is known at smaller spatial scales. The goal of this research was to evaluate relationships between ecosystem characteristics and bacterial community structure/function at broad taxonomic resolutions in soils across small spatial scales. We employed 16S rRNA gene sequencing, community-level physiological profiling and soil chemical analysis to address this goal.
