ReviewPrimer on machine learning: utilization of large data set analyses to individualize pain management.
Pain researchers and clinicians increasingly encounter machine learning algorithms in both research methods and clinical practice. This review provides a summary of key machine learning principles, as well as applications to both structured and unstructured datasets. ⋯ In the coming years, machine learning is likely to become a key component of evidence-based medicine, yet will require additional skills and perspectives for its successful and ethical use in research and clinical settings.

ReviewPatient-reported outcome measures for acute and chronic pain: current knowledge and future directions.
During the past years, patient-reported outcomes (PROs) and patient-reported outcome measures (PROMs) have become of growing awareness and importance in medical research and practice. This review summarizes recent developments concerning PROs and PROMs related to pain in the acute postoperative as well as chronic settings and indicates gaps and challenges relevant for future research and clinical applications. ⋯ COSs of PRO and PROMs are crucial in the field of research to enhance the comparability of results and reducing outcome reporting bias. In clinical practice PROs and PROMs are important for allocation of treatment. Concerning the development and implementation of PROs and PROMs patients' perspective should be thoroughly considered. Relating to acute as well as chronic pain there are some attempts to create COSs of PROs and PROMs but validity and reliability for both are still missing.

What is normal trauma healing, what is Complex Regional Pain Syndrome I? An analysis of clinical and experimental biomarkers.
Complex regional pain syndrome (CRPS) typically develops after fracture or trauma. Many of the studies so far have analyzed clinical and molecular markers of CRPS in comparison with healthy or pain controls. This approach, however, neglects mechanisms occurring during physiological trauma recovery. ⋯ In summary, normal trauma healing includes some CRPS signs and symptoms. It is the combination of different factors that distinguish CRPS and FC. Fracture control as a control group can assist to discover resolution factors after trauma.

Although the influence of genetics on chronic low back pain (LBP) has been previously examined, few studies have investigated whether the impact of genetic factors on LBP depends on how the condition is assessed. ⋯ Heritability estimates were similar for different low back pain definitions, and therefore not dependent on how chronic low back pain is experienced or assessed, in the same population-based sample.

The McGill Pain Questionnaire (MPQ) pain quality descriptors have been analyzed to characterize the sensory, affective, and evaluative domains of pain, but have not been differentiated by pain location. ⋯ This type of pain characterization is innovative and has the potential to help implement targeted treatments for patients with cancer and other chronic pain conditions.
