Multicenter Study
The Impact of Body Mass Index on Fluoroscopy Time During Lumbar Epidural Steroid Injection; A Multicenter Cohort Study.
This study aimed to assess the relationship between BMI and fluoroscopy time during lumbar epidural steroid injections (LESIs) performed for lumbosacral radicular pain. ⋯ The findings of this study indicate that fluoroscopy time is increased during interlaminar LESIs and during L5-S1 transforaminal LESIs in patients who are obese. These relationships are not affected by injection number, performance of bilateral injections, or trainee involvement. Further study is needed to determine if this increase in fluoroscopy time is indicative of a clinically significant associated increase in radiation dose.

To investigate whether pain catastrophizing and personality traits bias recalled ratings of acute pain in an experimental tonic pain model. ⋯ This study demonstrated that memory for painful events in healthy subjects was reasonably accurate over a period of 1 week. Pain catastrophizing biased pain recall, whereas among personality traits only neuroticism exhibited a weak positive association with the recalled ratings.

To identify variables correlated with a diagnosis of diabetic peripheral neuropathy (DPN) using random forest modeling applied to electronic health records. ⋯ Random forest modeling can determine likelihood of a DPN diagnosis. Further validation of the random forest model may help facilitate earlier diagnosis and enhance management strategies.

Randomized Controlled Trial
Validation of a New Placebo Interferential Current Method: A New Placebo Method of Electrostimulation.
The present study aimed to investigate if a new placebo device for interferential current (IFC) that delivers current during only the first 40 seconds of stimulation is effective at promoting adequate subject blinding. ⋯ The new method of placebo IFC was effective for blinding of research investigators and most of the active IFC-treated subjects, promoting an appropriate placebo method.
