Initial content validation and roadmap for a new patient-reported outcome measure of pain intensity.
Measures of pain intensity (eg, numeric rating scales [NRS]) are widely used in clinical research and practice. While these measures have evidence for validity and reliability, poor standardization of instructions, and response options limits precision of pain assessment, allows for inconsistency in interpretation, and presents a challenge for comparison and aggregation of study results. Despite these pitfalls, the 0 to 10 NRS remains the most commonly used primary outcome measure in clinical trials of pain treatments and is the core measure recommended by regulatory agencies. ⋯ This article summarizes interview findings, describes how patient input and FDA feedback informed preliminary candidate measures, and provides an overview of the FDA qualification process. PERSPECTIVE: Concept elicitation interviews informed the development of content-valid candidate measures of acute and chronic pain intensity for planned use in clinical trials of pain treatments, and comprise the initial stage in FDA clinical outcome assessment qualification. Measures will subsequently be evaluated through cognitive interviews and a series of psychometric studies.

Review Meta Analysis
Complete intraureteral stent placement reduces stent-related symptoms: Systemic review and meta-analysis.
The distal coil of a double-J ureteral stent is considered the major cause of stent-related symptoms. We noticed that some recent studies investigated whether complete intraureteral stent placement (CIU-SP) reduced these symptoms. The current systemic review and meta-analysis aimed to evaluate the safety and the effectiveness of CIU-SP, as compared to conventional stent placement (C-SP). ⋯ This meta-analysis reveals that CIU-SP significantly decreases stent-related urinary symptoms and pain. Based on the current evidence, CIU-SP is ready to be applied in clinical practice, at least in those requiring short-term stent placement following uncomplicated ureteroscopic lithotripsy.

To conduct a systematic review to identify which tools are being used to assess body perception disturbances in Complex Regional Pain Syndrome (CRPS) and to provide an evidence-based recommendation in the selection of an assessment tool, based on measurement properties. ⋯ This systematic review identified body perception disturbances assessment methods and their the psychometric properties in order to provide help and guidance to researchers and clinicians to investigate those clinical features.

The relationships between the morphometric structure of the patellofemoral joint, patella type and chondromalacia patella are still a matter of debate. ⋯ Detecting the patella type and making lateral inclination measurements in patients with anterior knee pain are of great importance for diagnosing suspected chondromalacia patella, particularly in the early degenerative period.

Review Meta Analysis
A Meta-analysis of the Associations of Elements of the Fear-Avoidance Model of Chronic Pain with Negative Affect, Depression, Anxiety, Pain-related Disability and Pain Intensity.
Biopsychosocial conceptualizations of clinical pain conditions recognize the multi-faceted nature of pain experience and its intersection with mental health. A primary cognitive-behavioural framework is the Fear-Avoidance Model, which posits that pain catastrophizing and fear of pain (including avoidance, cognitions and physiological reactivity) are key antecedents to, and drivers of, pain intensity and disability, in addition to pain-related psychological distress. This study aimed to provide a comprehensive analysis of the magnitude of the cross-sectional association between the primary components of the Fear-Avoidance Model (pain catastrophizing, fear of pain, pain vigilance) with negative affect, anxiety, depression, pain intensity and disabilities in studies of clinical pain. ⋯ This meta-analysis reveals that, among individuals with various pain conditions, pain catastrophizing, fear of pain, and pain vigilance have medium to large associations with pain- related negative affect, anxiety, and depression, pain intensity and disability. Differences in the strength of the associations depend on the type of self-report tool used to assess fear of pain.
