Opioids, musculoskeletal disorders, and work-related outcomes

Musculoskeletal disorders (MSDs) such as strains, sprains, fractures, and arthritis are a common cause of work disability and absenteeism. Current guidelines suggest that opioid medications should be prescribed for MSDs only when pain is severe and unresponsive to non-opioid analgesics. However, in some cases best practice guidelines are not being followed and opioids are overprescribed for MSDs, potentially contributing to work disability.

A sweet solution for reducing procedural pain in neonates

Sweet solutions have been repeatedly demonstrated to be analgesic in neonates undergoing medical procedures. Despite the extent of evidence for the efficacy of this intervention, clinical trials continue to be conducted using placebo/no-treatment groups. Thus, Dr. Bonnie Stevens and colleagues conducted a cumulative meta-analyses (CMAs) on the impact of sugar solutions on behavioural pain outcomes.

Diurnal variations in chronic pain are mediated by glucocorticoid regulation of ATP

Diurnal variations in symptoms of chronic pain patients have been widely reported. However, the underlying mechanisms for this phenonemon have yet to be delineated. UTCSP scientist Michael Salter has collaborated with scientists in Japan to help reveal the molecular mechanisms underlying diurnal variations in pain hypersensitivity.

Targeting adenylyl cyclase in bone cancer pain

Scientists in China have collaborated with UTCSP scientist Min Zhuo to investigate the potential mechanisms of bone cancer pain, a greatly understudied form of chronic pain. Patients with bone cancer experience severe pain at the site of the cancerous tumour, manifesting as continuous and/or spontaneous pain, and allodynia. This pain often becomes worse as the cancer progresses, greatly decreasing patient quality of life. Previous studies of other types of chronic pain have shown a role of the anterior cingulate cortex (ACC) and a compound called adenylyl cyclase (AC) in the development of the chronic pain condition. AC is activated when a neuron is very active, which triggers the production of cAMP and PKA, two second messengers involved in increased gene transcription and translation. This process works to increase glutamate receptor expression at the post-synaptic membrane, effectively potentiating synapses and increasing the fidelity of pain signals reaching the brain. In this study, the authors sought to determine whether this AC cascade in the ACC is also occurring in bone cancer pain models.

Variability in fMRI BOLD signal is a novel indicator of pain sensitivity and coping

Dr. Karen Davis and PhD student Anton Rogachov have recently discovered that regional blood oxygen level-dependent (BOLD) signal variability is a novel indicator of pain sensitivity and coping. Published online by PAIN in July, this study is the first to demonstrate a link between neural signal variability and an individual’s acute pain sensitivity and ability to cope with pain.

Connaught Summer Institute in Pain keynote lecture: Inhibition of tetrahydrobiopterin synthesis alleviates neuropathic and inflammatory pain

The Connaught Summer Institute in Pain brought pain research trainees from across the globe to Toronto to learn about the integration of research and clinical practice. The weeklong pain school culminated in a scientific meeting with keynote speaker Dr. Clifford Woolf, a renowned preclinical pain researcher based out of Boston Children's Hospital and Harvard University. Dr. Woolf discussed his recent research published in Neuron which highlighted the potential viability of targeting the tetrahydrobiopterin (BH4) synthesis pathway to treat inflammatory and neuropathic pain in humans.
