Use of a goal setting intervention to increase adherence to low back pain rehabilitation: A randomized controlled trial

Objective: To examine the effects of a goal setting intervention on self efficacy, treatment efficacy, adherence and treatment outcome in patients undergoing low back pain rehabilitation. Design: A mixed-model 2 (Time) x 3 (Group) randomized controlled trial. Setting: A residential rehabilitation centre for military personnel. Subjects: UK military personnel volunteers (N=48); mean age was 32.9 (SD 7.9) with a diagnosis of non-specific low back pain. Interventions: Subjects were randomly assigned to either a goal setting experimental group (Exp, n=16), therapist-led exercise therapy group (C1, n=16), or non-therapist-led exercise therapy group (C2, n=16). Treatment duration for all groups was 3 weeks. Main measures: Self-efficacy, treatment efficacy and treatment outcome were recorded before and after the treatment period. Adherence was rated during regularly scheduled treatment sessions using the Sports Injury Rehabilitation Adherence Scale (SIRAS). The Biering-Sørensen test was used as the primary measure of treatment outcome. Results: ANCOVA results showed that adherence scores were significantly higher in the experimental group (13.70 ± 1.58) compared with C2 (11.74 ± 1.35), (P<0.025). There was no significant difference for adherence between the experimental group and C1 (P=0.13). Self-efficacy was significantly higher in the experimental group compared to both C1 and C2 (P<0.05), whereas no significant difference was found for treatment efficacy. Treatment outcome did not differ significantly between the experimental and two control groups. Conclusions: The findings provide partial support for the use of goal setting to enhance adherence in clinical rehabilitation

Endomyocardial fibrosis associated with Schistosoma Haematobium infection

Endomyocardial fibrosis (EMF) is a form of restrictive cardiomyopathy common in the tropics and subtropics. The aetiology of EMF is unknown but helminth infestations such as schistosomiasis have been implicated. Two boys aged 8 and 10 years with EMF associated with Schistosoma haematobium, are described. The schistosomes in both cases may have been acquired from contact with contaminated water collected and stored in containers and subsequently used for bathing. Both patients were managed conservatively. Overall prognosis of EMF is poor and this report emphasizes the importance of public health  interventions in the control of schistosomiasis.Keywords: Endomyocardial fibrosis; Schistosoma haematobium; Cardiomyopathy; Ghana; Public health interventio

Psychological, psychophysical, and ergogenic effects of music in swimming

OBJECTIVES: Existing work using dry land exercise-related activities has shown that the careful application of music can lead to a range of benefits that include enhanced affect, lower perceived exertion, greater energy efficiency, and faster time trial performances. The purpose of this study was to assess the psychological, psychophysical, and ergogenic effects of asynchronous music in swimming using a mixed-methods approach. DESIGN: A mixed-model design was employed wherein there was a within-subjects factor (two experimental conditions and a control) and a between-subjects factor (gender). The experimental component of the study was supplemented by qualitative data that were analysed using inductive content analysis. METHODS: Twenty six participants (Mage = 20.0 years, age range: 18–23 years) underwent a period of habituation with Speedo Aquabeat MP3 players prior to the experimental phase. They were then administered two experimental trials (motivational and oudeterous music at 130 bpm) and a no-music control, during which they engaged in a 200-m freestyle swimming time trial. RESULTS: Participants swam significantly faster when exposed to either music condition relative to control (p = .022, ηp2=.18). Moreover, the music conditions were associated with higher state motivation (p = .016, ηp2=.15) and more dissociative thoughts (p = .014, ηp2=.16). CONCLUSIONS: Findings supported the hypothesis that the use of asynchronous music during a high-intensity task can have an ergogenic effect; this was in the order of 2% when averaged out across the two experimental conditions. The use of music, regardless of its motivational qualities, resulted in higher self-reported motivation as well as more dissociative thoughts

Spinal release of tumour necrosis factor activates c-Jun N-terminal kinase and mediates inflammation-induced hypersensitivity.

BackgroundMounting evidence points to individual contributions of tumour necrosis factor-alpha (TNF) and the c-Jun N-terminal kinase (JNK) pathway to the induction and maintenance of various pain states. Here we explore the role of spinal TNF and JNK in carrageenan-induced hypersensitivity. As links between TNF and JNK have been demonstrated in vitro, we investigated if TNF regulates spinal JNK activity in vivo.MethodsTNF levels in lumbar cerebrospinal fluid (CSF) were measured by enzyme-linked immunosorbent assay, spinal TNF gene expression by real-time polymerase chain reaction and TNF protein expression, JNK and c-Jun phosphorylation by western blotting. The role of spinal TNF and JNK in inflammation-induced mechanical and thermal hypersensitivity was assessed by injecting the TNF inhibitor etanercept and the JNK inhibitors SP600125 and JIP-1 intrathecally (i.t.). TNF-mediated regulation of JNK activity was examined by assessing the effect of i.t. etanercept on inflammation-induced spinal JNK activity.ResultsTNF levels were increased in CSF and spinal cord following carrageenan-induced inflammation. While JNK phosphorylation followed the same temporal pattern as TNF, c-jun was only activated at later time points. Intrathecal injection of TNF and JNK inhibitors attenuated carrageenan-induced mechanical and thermal hypersensitivity. TNF stimulation induced JNK phosphorylation in cultured spinal astrocytes and blocking the spinal actions of TNF in vivo by i.t. injection of etanercept reduced inflammation-induced spinal JNK activity.ConclusionsHere we show that spinal JNK activity is dependent on TNF and that both TNF and the JNK signalling pathways modulate pain-like behaviour induced by peripheral inflammation

The Neurospora crassa dfg5 and dcw1 Genes Encode α-1,6-Mannanases That Function in the Incorporation of Glycoproteins into the Cell Wall

The covalent cross-linking of cell wall proteins into the cell wall glucan/chitin matrix is an important step in the biogenesis of the fungal cell wall. We demonstrate that the Neurospora crassa DFG5 (NCU03770) and DCW1 (NCU08127) enzymes function in vivo to cross-link glycoproteins into the cell wall. Mutants lacking DFG5 or DCW1 release slightly elevated levels of cell wall proteins into their growth medium. Mutants lacking both DFG5 and DCW1 have substantially reduced levels of cell wall proteins in their cell walls and release large amounts of known cell wall proteins into the medium. DFG5 and DCW1 are members of the GH76 family of glycosyl hydrolases, which have specificity to recognize and cleave α-1,6-mannans. A model for incorporation of glycoproteins into the cell wall through the α-1,6-mannan core of the N-linked galactomannan is presented. In this model, DFG5 and DCW1 recognize the N-linked galactomannan present on glycoproteins and cross-link it into the cell wall glucan/chitin matrix

Autoimmune Pancreatitis with Associated Ulcerative Colitis in a Teenager

Autoimmune pancreatitis (AIP) is a rare entity that is extremely uncommon in children. Its diagnosis is also a clinical challenge. This form of chronic pancreatitis often presents itself with obstructive jaundice and/or a pancreatic mass and it is sometimes misdiagnosed as pancreatic cancer. We describe the case of a 13-year-old boy with obstructive jaundice and a 4 cm mass in the head of the pancreas that was diagnosed as AIP with associated ulcerative colitis.info:eu-repo/semantics/publishedVersio
