Common interventional procedures for chronic non-cancer #spine #pain: a systematic review and network meta-analysis of randomised trials

aledopress

Objective To address the comparative effectiveness of common interventional procedures for chronic non-cancer (axial or radicular) spine pain.Design Systematic review and network meta-analysis (NMA) of randomised controlled trials (RCTs).Data sources Medline, Embase, CINAHL, CENTRAL, and Web of Science from inception to 24 January 2023.Study selection RCTs that enrolled patients with chronic non-cancer spine pain, randomised… Continue reading Common interventional procedures for chronic non-cancer #spine #pain: a systematic review and network meta-analysis of randomised trials

The endocannabinoid N-arachidonoyl dopamine is critical for #hyperalgesia induced by chronic #sleep disruption

aledopress

Chronic pain is highly prevalent and is linked to a broad range of comorbidities, including sleep disorders. Epidemiological and clinical evidence suggests that chronic sleep disruption (CSD) leads to heightened pain sensitivity, referred to as CSD-induced hyperalgesia. However, the underlying mechanisms are unclear. The thalamic reticular nucleus (TRN) has unique integrative functions in sensory processing,… Continue reading The endocannabinoid N-arachidonoyl dopamine is critical for #hyperalgesia induced by chronic #sleep disruption

Opioid analgesia for acute low back pain and neck pain (the OPAL trial): a randomised placebo-controlled trial

aledopress

Opioid analgesics are commonly used for acute low back pain and neck pain, but supporting efficacy data are scarce. We aimed to investigate the efficacy and safety of a judicious short course of an opioid analgesic for acute low back pain and neck pain.MethodsOPAL was a triple-blinded, placebo-controlled randomised trial that recruited adults (aged ≥18… Continue reading Opioid analgesia for acute low back pain and neck pain (the OPAL trial): a randomised placebo-controlled trial

Effect of statin therapy on muscle symptoms: an individual participant data meta-analysis of large-scale, randomised, double-blind trials

aledopress

BackgroundStatin therapy is effective for the prevention of atherosclerotic cardiovascular disease and is widely prescribed, but there are persisting concerns that statin therapy might frequently cause muscle pain or weakness. We aimed to address these through an individual participant data meta-analysis of all recorded adverse muscle events in large, long-term, randomised, double-blind trials of statin… Continue reading Effect of statin therapy on muscle symptoms: an individual participant data meta-analysis of large-scale, randomised, double-blind trials

Neural Signatures of Pain Modulation in Short-Term and Long-Term Mindfulness Training: A Randomized Active-Control Trial

aledopress

Mindfulness-based interventions are widely used to target pain, yet their neural mechanisms of action are insufficiently understood. The authors studied neural and subjective pain response in a randomized active-control trial of mindfulness-based stress reduction (MBSR) alongside long-term meditation practitioners.Methods:Healthy participants (N=115) underwent functional neuroimaging during a thermal acute pain task before and after random assignment… Continue reading Neural Signatures of Pain Modulation in Short-Term and Long-Term Mindfulness Training: A Randomized Active-Control Trial

Disentangling self from pain: mindfulness meditation-induced pain relief is driven by thalamic-default mode network decoupling

aledopress

For millenniums, mindfulness was thought to diminish pain by reducing the influence of self-appraisals of noxious sensations. Today, mindfulness meditation is a highly popular and effective pain therapy that is thought to engage multiple, non-placebo related mechanisms to attenuate pain. Recent evidence suggests that mindfulness meditation-induced pain relief is associated with the engagement of unique… Continue reading Disentangling self from pain: mindfulness meditation-induced pain relief is driven by thalamic-default mode network decoupling

Early life inflammation is associated with spinal cord excitability and nociceptive sensitivity in human infants

aledopress

Immune function and sensitivity to pain are closely related, but the association between early life inflammation and sensory nervous system development is poorly understood—especially in humans. Here, in term-born infants, we measure brain activity and reflex withdrawal activity (using EEG and EMG) and behavioural and physiological activity (using the PIPP-R score) to assess the impact… Continue reading Early life inflammation is associated with spinal cord excitability and nociceptive sensitivity in human infants

Lidocaine infusions for refractory chronic migraine: a retrospective analysis

aledopress

Introduction Patients with refractory chronic migraine have poor quality of life. Intravenous infusions are indicated to rapidly ‘break the cycle’ of pain. Lidocaine infusions may be effective but evidence is limited. Methods The records of 832 hospital admissions involving continuous multiday lidocaine infusions for migraine were reviewed. All patients met criteria for refractory chronic migraine.… Continue reading Lidocaine infusions for refractory chronic migraine: a retrospective analysis
