S M Walker, H O'Reilly, J Beckmann, N Marlow
BACKGROUND: Conditioned pain modulation is a potential biomarker for risk of persistent pain. As early-life experience can alter subsequent somatosensory processing and pain response, we evaluated conditioned pain modulation after extremely preterm birth. METHODS: This observational study recruited extremely preterm (<26 weeks gestation; n=98) and term-born control (n=48) young adults (19-20 yr) from the longitudinal EPICure cohort. Pressure pain threshold (PPT; variable test stimulus lower leg) was measured before, during, and after a conditioning stimulus (contralateral hand immersion; 5°C water; 30 s)...

BACKGROUND: Surgery or multiple procedural interventions in extremely preterm neonates influence neurodevelopmental outcome and may be associated with long-term changes in somatosensory function or pain response. METHODS: This observational study recruited extremely preterm (EP, <26 weeks' gestation; n=102, 60% female) and term-born controls (TC; n=48) aged 18-20 yr from the UK EPICure cohort. Thirty EP but no TC participants had neonatal surgery. Evaluation included: quantitative sensory testing (thenar eminence, chest wall); clinical pain history; questionnaires (intelligence quotient; pain catastrophising; anxiety); and structural brain imaging...

Sex differences occur in nociceptive pain, and estrogens are involved in the sex differences. Our previous study shows sex differences exist in acidosis-induced nociception in rats, with females being more sensitive than males to acetic acid. However, the mechanisms underlying the sex differences remain unclear. We report here17β-estradiol (E2) up-regulates expression of acid-sensing ion channel 3 (ASIC3), which can mediate the acidosis-induced events. The recombinant plasmid of pCDNA3.1-ASIC3-GFP and pCDNA3...

BACKGROUND: Cervical collars are used after laminoplasty to protect the hinge opening, reduce risks of hinge fractures, and avoid spring-back phenomena. However, their use may lead to reduced range of motion and worse neck pain. OBJECTIVE: To investigate the clinical, radiological, and functional outcomes of patients undergoing single-door laminoplasty with or without collar immobilization. METHODS: This was a prospective, parallel, single-blinded randomized controlled trial...

BACKGROUND: Open reduction and internal fixation (ORIF) using plate osteosynthesis for midshaft clavicle fractures is often complicated by the prominence of the implant due to the subcutaneous position of the clavicle. Reoperation rates for symptomatic clavicle plate removal have been reported to be as high as 53%. We sought to determine to which degree do clinical outcomes (all cause reoperation rate and rate of fracture union) differ between types of clavicle plates. MATERIALS AND METHODS: A retrospective chart review was performed using our hospital database for patients treated with ORIF for mid-shaft clavicle fractures (OTA/AO type 15-B)...

Background: Associative learning has, in several studies, been modulated by the sex of the participant. Consistent with this, a recent review found that conditioned nocebo effects are stronger in females than in males. Purpose: It has been suggested that conditioned placebo responses are stronger in females, and this hypothesis was investigated in the present study. Cortisol and measures of negative emotions were taken to investigate if these processes could mediate any conditioned placebo effects. Methods: Cold pain was applied to the volar forearm...

BACKGROUND: Reports of the overall chronic pain prevalence and its associated demographic characteristics among adolescents vary greatly across existing studies. Using internationally comparable data, the present study investigates age, sex and country-level effects in the prevalence of chronic single-site and multi-site pain among adolescents during the last six months preceding the survey. METHODS: Data (n = 214,283) from the 2013/2014 Health Behaviour in School-aged Children (HBSC) study were used including nationally representative samples of 11-, 13- and 15-year-olds from general schools in 42 participating countries...

BACKGROUND: Hip osteoarthritis (OA) is a significant cause of disability, with hip pain and reduced external hip moments during walking being key features of the condition. The external hip adduction moment is greater in healthy women than men, however these between-sex differences are not evident in those with end-stage hip OA. Whether sex-specific hip kinetics are associated with early-midstage hip OA has not been investigated and may be a potential target for directed treatment. METHODS: Thirty-eight women and twenty-eight men with a diagnosis of symptomatic, unilateral, mild-to-moderate hip OA (Kellegren-Lawrence Grade 2 or 3) underwent three-dimensional gait analysis of normal walking gait using Vicon motion capture...

INTRODUCTION: Connectivity within the primary motor cortex can be measured using the paired-pulse transcranial magnetic stimulation (TMS) paradigm. This evaluates the effect of a first conditioning stimulus on the motor evoked potential (MEP) elicited by a second test stimulus when different interstimulus intervals are used. Aim of the present study was to provide, in patients suffering from migraine without aura (MwoA), additional information on intracortical facilitation (ICF), short intracortical inhibition (SICI), and long intracortical inhibition (LICI), using different intensities of the test stimulus (TS)...

Despite decompression surgery being a widespread intervention for patients with dorsopathies (i.e. back pain) affecting the lumbar spine, the scientific knowledge on patterns and characteristics of work disability before and after the surgery is limited. Sickness absence (SA) and disability pension (DP) were examined three years before and after surgery in 8558 patients aged 25-60 years who underwent lumbar spine decompression surgery in Sweden. They were compared to individuals with diagnosed dorsopathies but no surgery and individuals from the general population as matched comparison groups...

Activation of kappa opioid receptors (KOR) produces analgesia and aversion via distinct intracellular signaling pathways, but whether G protein-biased KOR agonists can be designed to have clinical utility will depend on a better understanding of the signaling mechanisms involved. We found that KOR activation produced conditioned place aversion and potentiated conditioned place preference for cocaine in male and female C57BL/6N mice. Consistent with this, males and females both showed arrestin-mediated increases in phospho-p38 MAPK following KOR activation...
