To identify clinical phenotypes of knee osteoarthritis (OA) using measures from the following domains: 1) multimorbidity; 2) psychological distress; 3) pain sensitivity; and 4) knee impairment or pathology. ⋯ Four phenotypes of knee OA were identified using psychological factors, comorbidity status, pain sensitivity, and leg strength. Follow-up analyses supported the replicability of this phenotype structure, but future research is needed to determine its usefulness in knee OA care.

Prospectively evaluate the clinical outcomes of acute cervical radiculopathy with respect to soft disc herniations vs osteophytes. ⋯ The majority of patients, but not all patients, with acute radiculopathies improved with time. This was seen with both soft disc herniations and osteophytes.

This is a prospective, blinded, case-control study of patients with chronic pain using body diagrams and colored markers to show the distribution and quality of pain and sensory symptoms (aching, burning, tingling, numbness, and sensitivity to touch) experienced in affected body parts. ⋯ This study demonstrates good performance characteristics of CPDs in identifying patients with NeuP through the use of a simple and easy-to-apply classification scheme. We suggest use of CPDs as a bedside screening tool and as a method for phenotypic profiling of patients by the quality and distribution of pain and sensory symptoms.

Pain continues to be an important public health concern, especially given the opioid crisis in industrialized countries. It is important to understand the association between emotions such as fear and anxiety and the experience of pain as both a physiological and affective experience. Fear or anxiety about pain is in fact a well-known predictor of and close associate of pain. Nociception and pain history differ depending on age, yet little empirical evidence exists on how fear of pain varies over the life span. The purpose of this study was to provide a cross-sectional examination of the relations between age and fear of pain across the adult life span. ⋯ Unique trajectories for different components of pain-related fear exist across the adult life span and may be affected by increased exposure to medical and dental experiences over time and by the awareness of a greater likelihood of experiencing pain later in the life span.
