Randomized Controlled Trial
Investigating the Causal Mechanisms of Symptom Recovery in Chronic Whiplash Associated Disorders Using Bayesian Networks.
The present study's objective was to understand the causal mechanisms underpinning the recovery of individuals with whiplash-associated disorders (WAD). We applied Bayesian Networks (BN) to answer 2 study aims: (1) to identify the causal mechanism(s) of recovery underpinning neck-specific exercise (NSE), and (2) quantify if the cyclical pathway of the fear-avoidance model (FAM) is supported by the present data. ⋯ We uncovered 2 mediators that explained the mechanisms of effect behind NSE, and proposed an alternative FAM pathway. The present study is the first to apply BN modelling to understand the causal mechanisms of recovery in WAD. In doing so, it is anticipated that such analytical methods could increase the precision of treatment of individuals with chronic WAD.

Trajectories of Pain Intensity Over One Year in Adults with Disabling Subacute or Chronic Neck Pain.
The objectives of this study were to describe the 1-year trajectories of disabling subacute or persistent neck pain and to investigate whether baseline age, sex, pain characteristics, and depressive symptoms are associated with such trajectories. ⋯ Most individuals with disabling subacute or chronic neck pain show improvement in pain intensity over a year. However, a quarter present unfavorable trajectories. High pain intensity at baseline, depressive symptoms, younger age, female sex, and sudden onset of pain are factors associated with unfavorable trajectories.

Remifentanil for Procedural Sedation and Analgesia in Central Venous Catheter Insertion: A Randomized, Controlled Trial.
Central venous catheter (CVC) insertion is a common practice for anesthetists, but this invasive procedure generates anxiety and pain in patients that are often underestimated. We compared target-controlled infusion of remifentanil and local lidocaine infiltration with placebo and local lidocaine infiltration to decrease pain scores during CVC placement. ⋯ Target-controlled infusion of remifentanil is an effective drug to reduce pain during CVC insertion in association with lidocaine-based local anesthesia, in conscious patients.
