Measuring pain-Physiological and self-rated measurements in relation to pain stimulation and anxiety.
The aim of the present study was to investigate how emotions influence pain, measured by one subjective self-rated measure, the numeric rating scale (NRS), and one objective physiological measure, the number of skin conductance responses (NSCR). ⋯ The NRS was strongly influenced by affective state, with higher pain ratings during more anxiety-like states, whereas NSCR correlated to the strength of electrical pain stimulation. That reported pain is moderated by anxiety, puts forward a discussion whether reduction of the anxiety level should be considered during analgesia treatment.

Randomized Controlled Trial
Application of a real-time pain monitoring system in Korean fibromyalgia patients: A pilot study.
Chronic pain is a debilitating condition which should be managed with integrated multidisciplinary approaches. To this end, accurate pain assessment should be the first step, and self-reporting pain assessment systems using smartphones or wearable devices are being introduced. The aim of the study was to evaluate the utility and efficacy of a real-time pain monitoring system using a wearable device, referred to as the Pain Assessment and Analysis System (PAAS), in patients with fibromyalgia, which is characterized by widespread chronic pain. ⋯ The proposed real-time pain monitoring system can be utilized for pain assessment in Korean fibromyalgia patients. Moreover, the system accurately reflects pain status and may help to alleviate pain.

ReviewPros and Cons of Clinically Relevant Methods to Assess Pain in Rodents.
The primary objective of preclinical pain research is to improve the treatment of pain. Decades of research using pain-evoked tests has revealed much about mechanisms but failed to deliver new treatments. Evoked pain-tests are often limited because they ignore spontaneous pain and motor or disruptive side effects confound interpretation of results. ⋯ A brief description of each method is presented along with an analysis of the advantages and limitations. The pros and cons of each test will help researchers identify the assessment tool most appropriate to meet their particular objective to assess pain in rodents. These tests provide another tool to unravel the mechanisms underlying chronic pain and help overcome the translational gap in drug development.

Comparative Study Observational Study
Nausea intensity as a reflector of early physical recovery after surgery.
To compare different levels of self-rated average nausea intensity with early physical recovery and determine if nausea can reflect recovery in patients undergoing general or orthopaedic surgery. ⋯ As postoperative nausea is common, regular assessments by healthcare professionals are needed. Assessment of nausea is of importance since it reflects physical recovery. This also shows the importance of treating nausea without delay. Using the NRS to measure nausea intensity is a simple method that is easy to use in clinic.

Randomized Controlled Trial
Gradual withdrawal of remifentanil delays initial post-operative analgesic demand after thyroid surgery; double-blinded, randomized controlled trial.
Mismanagement of remifentanil leads to severe side effects such as opioid-induced tolerance and hyperalgesia. Recently studies revealed an alternative withdrawal method to limit these side effects. A gradual withdrawal of remifentanil seems to be associated with less pain. The hypothesis of this double-blinded, randomized controlled trial was that a gradual withdrawal of remifentanil would be associated with less immediate post-operative pain compared to after an abrupt discontinuation of remifentanil in patients who underwent thyroid surgery. ⋯ Though overall morphine consumption, numeric rating scale scores, Ramsay Sedation Scale scores, and quality of recovery scores (QoR-40) are not altered, a gradual withdrawal of remifentanil after thyroid surgery is safe and associated with a delayed initial post-operative demand of analgesic drugs. The withdrawal process does, however, require vigilance and training.
