    A National Survey of Patient Completion of Cognitive Behavioral Therapy for Chronic Pain: The Role of Therapist Characteristics, Attempt Rates, and Modification
    (American Psychological Association, 2021) McGuire, Alan; Matthias, Marianne S.; Kukla, Marina; Henry, Nancy; Carter, Jessica; Flanagan, Mindy; Bair, Matthew J.; Murphy, Jennifer L.; Psychology, School of Science
    The implementation of evidence-based psychotherapies, including patient-level measures such as penetration and rates of successfully completing a course of therapy, has received increasing attention. While much attention has been paid to the effect of patient-level factors on implementation, relatively little attention has been paid to therapist factors (e.g., professional training, experience). Objective: The current study explores therapists' decisions to offer a particular evidence-based psychotherapy (cognitive behavioral therapy for chronic pain; CBT-CP), whether and how they modify CBT-CP, and the relationship between these decisions and patient completion rates. Methods: The study utilized survey responses from 141 Veterans Affairs therapists certified in CBT-CP. Results: Therapists reported attempting CBT-CP with a little less than one half of their patients with chronic pain (mean = 48.8%, s.d.=35.7). Therapist were generally split between reporting modifying CBT-CP for either very few or most of their patients. After controlling for therapist characteristics and modification, therapist-reported percentage of patients with attempted CBT-CP was positively associated with completion rates, t (111) = 4.57, p<.001. Conclusions: Therapists who attempt CBT-CP more frequently may experience better completion rates, perhaps due to practice effects or contextual factors that support both attempts and completion. Future research should examine this relationship using objective measures of attempt rates and completion.

    RNA immunoprecipitation to identify in vivo targets of RNA editing and modifying enzymes
    (Elsevier, 2021) Mukherjee, Priyanka; Kurup, Reshma Raghava; Hundley, Heather A.; Biology, School of Science
    The past decade has seen an exponential increase in the identification of individual nucleobases that undergo base conversion and/or modification in transcriptomes. While the enzymes that catalyze these types of changes have been identified, the global interactome of these modifiers is still largely unknown. Furthermore, in some instances, redundancy among a family of enzymes leads to an inability to pinpoint the protein responsible for modifying a given transcript merely from high-throughput sequencing data. This chapter focuses on a method for global identification of transcripts recognized by an RNA modification/editing enzyme via capture of the RNAs that are bound in vivo, a method referred as RNA immunoprecipitation (RIP). We provide a guide of the major issues to consider when designing a RIP experiment, a detailed experimental protocol as well as troubleshooting advice. The RIP protocol presented here can be readily applied to any organism or cell line of interest as well as both RNA modification enzymes and RNA-binding proteins (RBPs) that regulate RNA modification levels. As mentioned at the end of the protocol, the RIP assay can be coupled to high-throughput sequencing to globally identify bound targets. For more quantitative investigations, such as how binding of an RNA modification enzyme/regulator to a given target changes during development/in specific tissues or assessing how the presence or absence of RNA modification affects transcript recognition by a particular RBP (irrespective of a role for the RBP in modulating modification levels); the RIP assay should be coupled to quantitative real-time PCR (qRT-PCR).
