BACKGROUND: Opioid Use Disorder (OUD) causes significant morbidity and mortality among people experiencing homelessness. We aimed to explore the unique way in which OUD impacts individuals experiencing homelessness as part of a family. METHODS: We conducted semi-structured interviews with adults experiencing OUD staying in Boston-area family shelters along with dependent children. We used Borkan's Immersion-Crystallization method to uncover themes from interview transcripts...

Targeting parents' responses to their child's pain during intensive interdisciplinary pain treatment (IIPT) could influence child functioning. This longitudinal, observational study investigated changes in these responses and concurrent relationships between parent responses and changes in levels of child functioning and pain. Parents of youth age 10-19 years (M=15, SD=1.98) participated in twice weekly, parent-only groups while their teens were enrolled in IIPT (mean length of treatment 3.93 weeks, SD=1.16)...

Fear-avoidance models propose that pain-related fear may spur avoidance behaviour leading to chronic pain disability. Pain-related fear elicits avoidance behaviour, which is typically aimed at reducing fear. We hypothesized that engaging in avoidance may (paradoxically) increase rather than decrease pain-related fear (i.e. bidirectionality hypothesis). In a between-subject design, participants (N=64) were randomly assigned to the avoidance group or the control group. Avoidance group participants were led to believe they could avoid full exposure to a painful heat stimulus by pressing the stop-button, while control group participants believed they were exposed to the full painful heat stimulus at all times...

Nitric oxide has been proven to play an important role in nociception, accordingly, its promoters, phosphodiesterase inhibitors have been investigated as pain response modulators. Aiming to evaluate the central effect of tadalafil, a phosphodiesterase 5 inhibitor, and to determine its EC50, tail flick and hot plate tests were utilized. On the other hand, its nociceptive peripheral analgesic effect was assessed through acetic-acid induced writhing model. Formalin test was used to appraise both non-inflammatory and inflammatory pain responses...

Postsynaptic density-95 (PSD-95) is a synaptic scaffolding protein that plays a crucial role in the development of neuropathic pain. However, the underlying mechanism remains unclear. To address the role of PSD-95 in N-methyl-D-aspartate receptor subtype 2B (NR2B) -mediated chronic pain, we investigated the relationship between PSD-95 activation and NR2B function in the spinal cord, by using a rat model of sciatic nerve chronic constriction injury (CCI). We demonstrate that the expression levels of total PSD-95 and cAMP response element binding protein (CREB), as well as phosphorylated NR2B, PSD-95, and CREB, in the spinal dorsal horn, and the interaction of NR2B with PSD-95 were increased in the CCI animals...

PURPOSE: An increased likelihood of developing obesity-related knee osteoarthritis may be associated with increased peak internal knee abduction moments (KAbM). Increases in step width (SW) may act to reduce this moment. The purpose of this study was to determine the effects of increased SW on knee biomechanics during stair negotiation of healthy-weight and obese participants. METHODS: Participants (24: 10 obese and 14 healthy-weight) used stairs and walked over level ground while walking at their preferred speed in two different SW conditions - preferred and wide (200% preferred)...

Latent sensitization is a model of chronic pain in which an injury triggers a period of hyperalgesia followed by an apparent recovery, but in which pain sensitization persists but is suppressed by opioid and adrenergic receptors. One important characteristic of latent sensitization is that hyperalgesia can be triggered by acute stress. To determine whether the effect of stress is mimicked by the activation of corticotropin-releasing factor (CRF) signaling in the brain, rats with latent sensitization induced by injecting complete Freund's adjuvant (CFA, 50 μl) in one hind paw were given an intracerebroventricular (i...

BACKGROUND: A small, but unstable, saw-gap may hinder bone-bridging and induce development of painful sternal dehiscence. We propose the use of Radiostereometric Analysis (RSA) for evaluation of sternal instability and present a method validation. METHODS: Four bone analogs (phantoms) were sternotomized and tantalum beads were inserted in each half. The models were reunited with wire cerclage and placed in a radiolucent separation device. Stereoradiographs (n = 48) of the phantoms in 3 positions were recorded at 4 imposed separation points...

On the basis of the S2-k guideline "Rehabilitation after traumatic fractures of the thoracic und lumbar spine without neurologic disorder", this article gives an overview of target-oriented rehabilitation of patients with minor fractures or those with column stability and unstable spinal fractures which are stabilised by surgery. To obtain early social and job related reintegration, outpatient or inpatient rehabilitation has to start immediately after treatment in hospital. Rehabilitation must be orientated towards the biopsychosocial model of ICF and has to be adapted for the patient...

BACKGROUND: Torsional deformities of the femur and tibia are associated with gait impairments and joint pain. Several studies have investigated these gait deviations in children with cerebral palsy. However, relatively little is known about gait deviations in children with idiopathic torsion and debate ensues about the management of these patients. RESEARCH QUESTION: What are the effects of idiopathic increased femoral neck anteversion and external tibial torsion on lower-limb kinematics, kinetics and joint loading during gait in children and adolescents...

INTRODUCTION: Shoulder pain is highly prevalent in competitive swimmers, and generalized joint hypermobility (GJH) is considered a risk factor. Sensorimotor control deficiencies and altered neuromuscular activation of the shoulder may represent underlying factors. RESEARCH QUESTION: To investigate whether competitive swimmers with GJH including shoulder hypermobility (GJHS) differ in shoulder sensorimotor control and muscle activity from those without GJH and no shoulder hypermobility (NGJH)...

OBJECTIVE: Effective disease-modifying drugs for osteoarthritis (DMOAD) should preferably have chondroprotective, anti-inflammatory, and analgesic activity combined in a single molecule. We developed a fusion protein of IL4 and IL10 (IL4-10 FP), in which the biological activity of both cytokines is preserved. The present study evaluates the chondroprotective, anti-inflammatory, and analgesic activity of IL4-10 FP in in vitro and in vivo models of osteoarthritis. METHODS: Human osteoarthritic cartilage tissue and synovial tissue were cultured with IL4-10 FP...

Over 1.4 million Americans have been diagnosed with inflammatory bowel disease (IBD), and ulcerative colitis (UC) makes up approximately half of those diagnoses. As a disease, UC cycles between periods of remission and flare, which is characterized by intense abdominal pain, increased weight loss, intestinal inflammation, rectal bleeding, and dehydration. Interestingly, a widespread recommendation to IBD patients for avoidance of a flare period is "Don't Drink Alcohol" as recent work correlated alcohol consumption with increased GI symptoms in patients with IBD...

BACKGROUND: Pain is a major non motor symptom that contributes to impaired quality of life in PD. However, its mechanism is unknown. OBJECTIVES AND METHODS: We sought to identify the pain phenotypes and parallel changes in spinal integration of peripheral stimuli in a rat model of PD induced by lesions of SN dopamine neurons, using behavioral plantar and von Frey tests as well as electrophysiology of the dorsal horn. RESULTS: We show that dopamine depletion by 6-OHDA induced hypersensitivity to mechanical and thermal stimuli...

Neurogenic bladder occur as a consequence of several conditions, most commonly posterior urethral valves syndrome, spina bifida, tethered cord, sacral agenesis, and Arnold-Chiari malformation. It is characterized by diminished bladder capacity and/or reduced compliance, associated with high-pressure voiding that can lead to deterioration of renal function if left untreated. When medical management fails, bladder reconstruction with bowel (aumentation ileocystoplasty) becomes the treatment of choice for these patients...

Abnormalities of neurovascular interactions within the central nervous system of diabetic patients is associated with the onset of many neurological disease states. However, to date, the link between the neurovascular network within the spinal cord and regulation of nociception has not been investigated despite neuropathic pain being common in diabetes. We hypothesised that hyperglycaemia-induced endothelial degeneration in the spinal cord, due to suppression of VEGF-A/VEGFR2 signalling, induces diabetic neuropathic pain...

Background: Evidence is overwhelming for sex differences in pain, with women representing the majority of the chronic pain patient population. There is a need to explore novel avenues to elucidate this sex bias in the development of chronic inflammatory pain conditions. Complex regional pain syndrome (CRPS) is a chronic neuropathic pain disorder, and the incidence of CRPS is greater in women than in men by ~4:1. Since neurogenic inflammation is a key feature of CRPS, dysregulation of inflammatory responses can be a factor in predisposing women to chronic pain...

Appropriate treatment of pain requires analgesics and anti-inflammatory drugs generally associated with undesirable side effects and not fully effective in a significant proportion of patients. Organoselenium compounds elicit a plenty of pharmacological effects in different animal models. Among these compounds, the 2,2`-dipyridyl diselenide (DPD) has a potent antioxidant effect and low toxicity. In this way, the aim of this study was to investigate the possible DPD antinociceptive effect and its mechanism of action, as well as the safety of the compound...

Traditionally, there has been a widely accepted notion that the transition from acute to chronic pain follows a linear trajectory, where an injury leads to acute episodes, subacute stages, and progresses to a chronic pain condition. However, it appears that pain progression is much more complicated and individualized than this original unsupported assumption. It is now becoming apparent that, while this linear progression may occur, it is not the only path that pain, specifically low-back pain, follows. It is clear there is a definite need to evaluate how low-back pain trajectories are classified and, subsequently, how we can more effectively intervene during these progression stages...
