The German Research Network on Neuropathic Pain (DFNS) quantitative sensory testing (QST) method for sensory phenotyping is used to stratify patients by mechanism-associated sensory phenotype, theorised to be predictive of intervention efficacy. We hypothesised that change in pain and sensory dysfunction would relate to change in sensory phenotype. We investigated the responsiveness of sensory phenotype to surgery in patients with an entrapment neuropathy. With ethical approval and consent, this observational study recruited patients with neurophysiologically confirmed carpal tunnel syndrome. Symptom and pain severity parameters and DFNS QST were evaluated before and after carpal tunnel surgery. Surgical outcome was evaluated by patient-rated change. Symptom severity score of the Boston Carpal Tunnel Questionnaire and associated pain and paraesthesia subgroups were comparators for clinically relevant change. Quantitative sensory testing results (n = 76) were compared with healthy controls (n = 54). At 6 monin and symptom severity (P less then 0.001). Change in QST parameters occurred for thermal detection, thermal pain, and mechanical detection thresholds with a moderate to large effect size. Change in mechanical pain measures was not statistically significant. GSK2656157 in vitro Change occurred in sensory phenotype postsurgery (P less then 0.001); sensory phenotype was associated with symptom subgroup (P = 0.03) and patient-rated surgical outcome (P = 0.02). Quantitative sensory testing-derived sensory phenotype is sensitive to clinically important change. In an entrapment neuropathy model, sensory phenotype was associated with patient-reported symptoms and demonstrated statistically significant, clinically relevant change after disease-modifying intervention. Sensory phenotype was independent of disease severity and may reflect underlying neuropathophysiology.
Little is known about the effectiveness of placebo interventions in patients with non-specific low back pain (LBP). This systematic review assessed the magnitude of the effects of placebo interventions as compared to no intervention in randomized controlled trials(RCTs) including patients with LBP. Embase, Medline(Ovid) and Cochrane CENTRAL databases were searched from inception to December 5th, 2019. RCTs comparing placebo intervention versus no intervention in adult patients with non-specific LBP were included. Pain intensity, physical functioning and health-related quality of life (hrQoL) measured at short-, medium- and long-term follow-up were the outcomes of this review. Twenty-one RCTs were included; one concerning acute LBP and one sub-acute LBP, while 19 studies reported on chronic LBP. In chronic LBP, placebo interventions were more effective than no intervention at short-term for pain intensity [standardized mean difference (SMD) = -0.37, 95% CI = -0.55 to -0.18, moderate quality evidence], physica was available at long-term follow-up. These results show placebo interventions are more effective than no intervention at short-term in patients with chronic LBP. However, the magnitude of the effects is probably not clinically relevant (approximately 8 points on a 0-100 pain scale). Future research should identify effect modifiers and causal mechanisms explaining the short-term effects of placebo interventions in patients with chronic LBP.

Lamina I of the dorsal horn, together with its main output pathway, lamina I projection neurons, have long been implicated in the processing of nociceptive stimuli, as well as the development of chronic pain conditions. However, the study of lamina I projection neurons is hampered by technical challenges, including the low throughput and selection biases of traditional electrophysiological techniques. Here we report on a technique which employs anatomical labelling strategies and in vivo imaging to simultaneously study a network of lamina I projection neurons in response to electrical and natural stimuli. While we were able to confirm the nociceptive involvement of this group of cells, we also describe an unexpected preference for innocuous cooling stimuli. We were able to characterize the thermal responsiveness of these cells in detail and found cooling responses decline when exposed to stable cold temperatures maintained for more than a few seconds, as well as to encode the intensity of the end temperaturr more than a few seconds, as well as to encode the intensity of the end temperature, while heating responses showed an unexpected reliance on adaptation temperatures.
Deprescribing opioids has been identified as an intervention to mitigate opioid harm, however, it is often challenging to implement interventions and communicate deprescribing decisions to consumers. The development of opioid deprescribing guidelines may provide guidance and support on when and how to reduce or cease opioids in routine care. This study aimed to explore the perspectives of opioid consumers on opioid deprescribing and determine factors to be considered in the development of opioid deprescribing guidelines. A purposive sample of twenty consumers using opioids for pain were recruited. Semi-structured interviews were conducted, audio recorded and transcribed verbatim. Inductive thematic analysis was undertaken, followed by a framework analysis informed by Bandura's Social Cognitive Theory. Behavioral, cognitive and environmental factors influence consumers' attitudes and actions regarding opioid deprescribing. Significant barriers to opioid deprescribing were identified, including fears of pain s of care, as well as the provision of greater opportunities for consumer engagement in decision making were identified as avenues to improve the success of opioid deprescribing. For opioid deprescribing guidelines to be effective and achieve the intended goal of optimizing opioid use, consumers need to feel empowered to engage in opioid reduction or cessation. The findings of this study may facilitate a patient-centred approach for practitioners and guideline developers in creating recommendations and interventions to enable opioid deprescribing through targeting behavioral change.
