The mechanical and inflammatory low back pain (MIL) index: development and validation

Abstract Background The purpose of this study was the development of a valid and reliable “Mechanical and Inflammatory Low Back Pain Index” (MIL) for assessment of non-specific low back pain (NSLBP). This 7-item tool assists practitioners in determining whether symptoms are predominantly mechanical or inflammatory. Methods Participants (n = 170, 96 females, age = 38 ± 14 years-old) with NSLP were referred to two Spanish physiotherapy clinics and completed the MIL and the following measures: the Roland Morris Questionnaire (RMQ), SF-12 and “Backache Index” (BAI) physical assessment test. For test-retest reliability, 37 consecutive patients were assessed at baseline and three days later during a non-treatment period. Face and content validity, practical characteristics, factor analysis, internal consistency, discriminant validity and convergent validity were assessed from the full sample. Results A total of 27 potential items that had been identified for inclusion were subsequently reduced to 11 by an expert panel. Four items were then removed due to cross-loading under confirmatory factor analysis where a two-factor model yielded a good fit to the data (χ2 = 14.80, df = 13, p = 0.37, CFI = 0.98, and RMSEA = 0.029). The internal consistency was moderate (α = 0.68 for MLBP; 0.72 for ILBP), test-retest reliability high (ICC = 0.91; 95%CI = 0.88-0.93) and discriminant validity good for either MLBP (AUC = 0.74) and ILBP (AUC = 0.92). Convergent validity was demonstrated through similar but weak correlations between the ILBP and both the RMQ and BAI (r = 0.34, p < 0.001) and the MLBP and BAI (r = 0.38, p < 0.001). Conclusions The MIL is a valid and reliable clinical tool for patients with NSLBP that discriminates between mechanical and inflammatory LBP.

Efficacy and safety of adalimumab in patients with non-radiographic axial spondyloarthritis: Results of a randomised placebo-controlled trial (ABILITY-1)

Purpose: To evaluate the efficacy and safety of adalimumab in patients with non-radiographic axial spondyloarthritis (nr-axSpA). Methods: Patients fulfilled Assessment of Spondyloarthritis international Society (ASAS) criteria for axial spondyloarthritis, had a Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score of ≥ 4, total back pain score of ≥ 4 (10 cm visual analogue scale) and inadequate response, intolerance or contraindication to non-steroidal anti-inflammatory drugs (NSAIDs); patients fulfilling modified New York criteria for ankylosing spondylitis were excluded. Patients were randomised to adalimumab (N=91) or placebo (N=94). The primary endpoint was the percentage of patients achieving ASAS40 at week 12. Efficacy assessments included BASDAI and Ankylosing Spondylitis Disease Activity Score (ASDAS). MRI was performed at baseline and week 12 and scored using the Spondyloarthritis Research Consortium of Canada (SPARCC) index. Results: Significantly more patients in the adalimumab group achieved ASAS40 at week 12 compared with patients in the placebo group (36% vs 15%, p<0.001). Significant clinical improvements based on other ASAS responses, ASDAS and BASDAI were also detected at week 12 with adalimumab treatment, as were improvements in quality of life measures. Inflammation in the spine and sacroiliac joints on MRI significantly decreased after 12 weeks of adalimumab treatment. Shorter disease duration, younger age, elevated baseline C-reactive protein or higher SPARCC MRI sacroiliac joint scores were associated with better week 12 responses to adalimumab. The safety profile was consistent with what is known for adalimumab in ankylosing spondylitis and other diseases. Conclusions: In patients with nr-axSpA, adalimumab treatment resulted in effective control of disease activity, decreased inflammation and improved quality of life compared with placebo. Results from ABILITY-1 suggest that adalimumab has a positive benefit-risk profile in active nr-axSpA patients with inadequate response to NSAIDs.

Spinal inflammation in the absence of sacroiliac joint inflammation on magnetic resonance imaging in patients with active nonradiographic axial spondyloarthritis

Objective: To evaluate the presence of spinal inflammation with and without sacroiliac (SI) joint inflammation on magnetic resonance imaging (MRI) in patients with active nonradiographic axial spondyloarthritis (SpA), and to compare the disease characteristics of these subgroups. Methods: ABILITY-1 is a multicenter, randomized, controlled trial of adalimumab versus placebo in patients with nonradiographic axial SpA classified using the Assessment of SpondyloArthritis international Society axial SpA criteria. Baseline MRIs were centrally scored independently by 2 readers using the Spondyloarthritis Research Consortium of Canada (SPARCC) method for the SI joints and the SPARCC 6-discovertebral unit method for the spine. Positive evidence of inflammation on MRI was defined as a SPARCC score of >2 for either the SI joints or the spine. Results: Among patients with baseline SPARCC scores, 40% had an SI joint score of >2 and 52% had a spine score of >2. Forty-nine percent of patients with baseline SI joint scores of <2, and 58% of those with baseline SI joint scores of >2, had a spine score of >2. Comparison of baseline disease characteristics by baseline SI joint and spine scores showed that a greater proportion of patients in the subgroup with a baseline SPARCC score of >2 for both SI joints and spine were male, and patients with spine and SI joint scores of <2 were younger and had shorter symptom duration. SPARCC spine scores correlated with baseline symptom duration, and SI joint scores correlated negatively with the baseline Bath Ankylosing Spondylitis Disease Activity Index, but neither correlated with the baseline Ankylosing Spondylitis Disease Activity Score, total back pain, the patient's global assessment of disease activity, the Bath Ankylosing Spondylitis Functional Index, morning stiffness, nocturnal pain, or C-reactive protein level. Conclusion: Assessment by experienced readers showed that spinal inflammation on MRI might be observed in half of patients with nonradiographic axial SpA without SI joint inflammation.

Validation of a Spanish version of the Spine Functional Index

Background The Spine Functional Index (SFI) is a recently published, robust and clinimetrically valid patient reported outcome measure. Objectives The purpose of this study was the adaptation and validation of a Spanish-version (SFI-Sp) with cultural and linguistic equivalence. Methods A two stage observational study was conducted. The SFI was cross-culturally adapted to Spanish through double forward and backward translation then validated for its psychometric characteristics. Participants (n = 226) with various spine conditions of >12 weeks duration completed the SFI-Sp and a region specific measure: for the back, the Roland Morris Questionnaire (RMQ) and Backache Index (BADIX); for the neck, the Neck Disability Index (NDI); for general health the EQ-5D and SF-12. The full sample was employed to determine internal consistency, concurrent criterion validity by region and health, construct validity and factor structure. A subgroup (n = 51) was used to determine reliability at seven days. Results The SFI-Sp demonstrated high internal consistency (α = 0.85) and reliability (r = 0.96). The factor structure was one-dimensional and supported construct validity. Criterion specific validity for function was high with the RMQ (r = 0.79), moderate with the BADIX (r = 0.59) and low with the NDI (r = 0.46). For general health it was low with the EQ-5D and inversely correlated (r = −0.42) and fair with the Physical and Mental Components of the SF-12 and inversely correlated (r = −0.56 and r = −0.48), respectively. The study limitations included the lack of longitudinal data regarding other psychometric properties, specifically responsiveness. Conclusions The SFI-Sp was demonstrated as a valid and reliable spine-regional outcome measure. The psychometric properties were comparable to and supported those of the English-version, however further longitudinal investigations are required.

Novel ANKH amino terminus mutation (Pro5Ser) associated with early-onset calcium pyrophosphate disease with associated phosphaturia

This report describes a 32-year-old woman presenting since childhood with progressive calcium pyrophosphate disease (CPPD), characterized by severe arthropathy and chondrocalcinosis involving multiple peripheral joints and intervertebral disks. Because ANKH mutations have been previously described in familial CPPD, the proband's DNA was assessed at this locus by direct sequencing of promoter and coding regions and revealed 3 sequence variants in ANKH. Sequences of exon 1 revealed a novel isolated nonsynonymous mutation (c.13 C>T), altering amino acid in codon 5 from proline to serine (CCG>TCG). Sequencing of parental DNA revealed an identical mutation in the proband's father but not the mother. Subsequent clinical evaluation demonstrated extensive chondrocalcinosis and degenerative arthropathy in the proband's father. In summary, we report a novel mutation, not previously described, in ANKH exon 1, wherein serine replaces proline, in a case of early-onset severe CPPD associated with metabolic abnormalities, with similar findings in the proband's father.

Evidence-based recommendations for the diagnosis of ankylosing spondylitis: Results from the Australian 3E initiative in rheumatology

• As part of the 3E program, we conducted a systematic literature review and gathered consensus from 23 practising Australian rheumatologists to develop guidelines for early identification of ankylosing spondylitis and specialist referral. • In three rounds of break-out sessions followed by discussion and voting, the specialist panel addressed three questions related to diagnosis of ankylosing spondylitis: In individuals with back pain, what are the early clinical features that suggest ankylosing spondylitis? How useful is imaging in identifying early ankylosing spondylitis? Based on which clinical features should a general practitioner refer a patient to a rheumatologist for further evaluation? • The panel agreed on six recommendations related to the three questions: 1a. Early clinical features to suggest ankylosing spondylitis include inflammatory back pain and age at symptom onset < 45 years. 1b. The absence of symptomatic response to an appropriate course of non-steroidal anti-inflammatory drugs makes the diagnosis of ankylosing spondylitis less likely. 1c. Raised inflammatory markers are supportive, but their absence does not rule out the diagnosis of ankylosing spondylitis. 2a. Despite low sensitivity to detect changes of early ankylosing spondylitis, plain radiographs of the pelvis and spine are appropriate initial imaging techniques. 2b. Magnetic resonance imaging is a useful imaging modality for detecting early changes of ankylosing spondylitis. 3. Individuals with inflammatory back pain should be referred to a rheumatologist for further evaluation. • Effective dissemination and implementation of these recommendations are important to standardise the approach to early diagnosis of ankylosing spondylitis.

A pesquisa teve como objeto de estudo os fatores de riscos ocupacionais e os problemas de saúde decorrentes do trabalho, identificados pelos profissionais de enfermagem de um Centro Cirúrgico de um Hospital Universitário da cidade do Rio de Janeiro. Os objetivos foram: analisar os fatores de riscos ocupacionais que possibilitam o aparecimento de problemas de saúde nos profissionais de enfermagem do Centro Cirúrgico segundo esses trabalhadores; descrever as características sociodemográficas dos profissionais lotados no Centro Cirúrgico; levantar os fatores de risco do ambiente cirúrgico identificados pelos trabalhadores de enfermagem do Centro Cirúrgico de um Hospital Universitário; e, discutir a relação entre os riscos do ambiente de trabalho e os problemas de saúde autoreferidos por trabalhadores de enfermagem do Centro Cirúrgico. A metodologia usada foi uma pesquisa não-experimental, de natureza descritiva, com abordagem quantitativa, desenvolvida em um centro cirúrgico de um hospital universitário federal da cidade do Rio de Janeiro. A população escolhida foi composta de trabalhadores da equipe de enfermagem, lotados no mínimo há seis meses neste serviço e que aceitassem participar da pesquisa. O questionário de coleta de dados utilizado foi adaptado por Mauro dos Guias e Avaliação de riscos em indústrias de Boix e Vogel. O estudo foi submetido e aprovado pelo Comitê de Ética em Pesquisa (CEP) do Hospital Universitário em estudo, através Parecer Consubstanciado no. 287/10, protocolo no. 217/09. Os dados foram analisados através do Programa Statistical Package for the Social Sciences (SPSS), versão 13.0. Os riscos biológicos foram os mais apontados pelos trabalhadores de enfermagem, seguidos dos riscos químicos, ergonômicos e de acidentes ou mecânicos. As doenças provocadas pelo trabalho mais referidas foram o estresse, a lombalgia, as varizes, a fadiga muscular e os problemas de articulação. As doenças agravadas pelo trabalho mais citadas foram as varizes, a lombalgia, os problemas de articulação, o estresse, as lesões de coluna vertebral, os problemas digestivos e os transtornos do sono. Conclui-se que o Serviço estudado possui riscos inerentes às atividades desenvolvidas que caracterizam os problemas relacionados pelos trabalhadores, e que são passíveis de controle através da intensificação de um Programa de Prevenção de Riscos Ambientais voltado para o Centro Cirúrgico. A partir da NR 17 e a 32, pode-se consultar as diretrizes para prevenção dos riscos encontrados. Uma estratégia de reposição digna de pessoal de enfermagem é imprescindível, assim como estudo e implantação de um Programa de Prevenção de Riscos laborais aos trabalhadores do Centro Cirúrgico, e utilização do questionário aos demais membros da equipe multiprofissional.

Is Internet use unhealthy? A cross-sectional study of adolescent Internet overuse.

OBJECTIVE: To assess whether problematic internet use is associated with somatic complaints and whether this association remains when checking for internet activity among a random sample of adolescents living in the canton of Vaud, Switzerland. METHODS: Cross-sectional survey of 3,067 8th graders (50.3% females) divided into average (n = 2,708) and problematic (n = 359) Internet users and compared for somatic complaints (backache, overweight, headaches, musculoskeletal pain, sleep problems and sight problems) controlling for sociodemographic and internet-related variables. Logistic regressions were performed for each complaint and for all of them simultaneously controlling variables significant at the bivariate level. RESULTS: At the multivariate level, when taken separately, problematic internet users were more likely to have a chronic condition (adjusted odds ratio [aOR] with 95% CI: 1.58 [1.11:2.23]) and to report back pain (aOR: 1.46 [1.04:2.05]), overweight (aOR: 1.74 [1.03:2.93]), musculoskeletal pain (aOR: 1.36 [1.00:1.84]) and sleep problems (aOR: 2.16 [1.62:2.88]). When considered in the full model, only sleep problems remained significant (aOR: 2.03 [1.50:2.74]). CONCLUSIONS: Our results confirm that problematic internet users report health problems more frequently, with lack of sleep being the most strongly associated and seeming to act as mediator regarding the other ones. Clinicians should remember to screen for excessive internet use their patients complaining of sleep-related problems, back or musculoskeletal pain or overweight. Clinicians should advise parents to limit the amount of time their adolescent children can spend online for leisure activities. Furthermore, limiting the number of devices used to connect to the internet could help warrant enough sleeping time.

A phenomenological approach to understanding the psychological response to chronic low back pain

Chronic low back pain (CLBP) is a complex health problem of psychological manifestations not fully understood. Using interpretive phenomenological analysis, 11 semi-structured interviews were conducted to help understand the meaning of the lived experience of CLBP; focusing on the psychological response to pain and the role of depression, catastrophizing, fear-avoidance behavior, anxiety and somatization. Participants characterized CLBP as persistent tolerable low back pain (TLBP) interrupted by periods of intolerable low back pain (ILBP). ILBP contributed to recurring bouts of helplessness, depression, frustration with the medical system and increased fear based on the perceived consequences of anticipated recurrences, all of which were mediated by the uncertainty of such pain. During times of TLBP all participants pursued a permanent pain consciousness as they felt susceptible to experience a recurrence. As CLBP progressed, participants felt they were living with a weakness, became isolated from those without CLBP and integrated pain into their self-concept.

Las actividades laborales informales presentan situaciones adversas frente a la exposición a riesgos de diferente origen, una de estas actividades que se ha convertido en alternativa de transporte en la ciudad de Bogotá es el bicitaxismo, el cual aporta soluciones a la movilidad de los habitantes. Con el fin de determinar las condiciones de trabajo y las posibles enfermedades que puedan adquirir como consecuencia de su actividad laboral, se realizó un estudio de corte transversal, con una población de 150 bicitaxistas pertenecientes al barrio Toberín de la localidad de Usaquén, de la ciudad de Bogotá. Para la recolección de datos se aplicó el Cuestionario Sobre Condiciones De Trabajo Y Salud. Se estimó la proporción de trabajadores con afectación de su estado de salud y se exploraron las posibles asociaciones mediante la prueba Chi cuadrado de Pearson o prueba exacta de Fisher. Se encontró una relación entre la edad y los dolores de espalda (p = 0,007), al igual que entre la edad y los dolores en miembros superiores (p= 0,001), así mismo, se observó una relación entre el estado de las vías (aberturas y huecos) por las que transitan los bicitaxistas, con el dolor de miembros superiores (p= 0,007). El bicitaxismo en una alternativa de trabajo y de transporte para la comunidad, que debido a las condiciones en las que laboran, se están generando dolencias en diferentes segmentos corporales.

Análise das condições de saúde e de vida da população urbana de Botucatu, SP (Brasil): III - Conhecimentos e opiniões dos profissionais de saúde a respeito de sintomas de doenças, 1984

Foram estudados os conhecimentos e opiniões dos profissionais de saúde do Município de Botucatu, SP (Brasil), acerca da freqüência e gravidade de treze sintomas e sinais de doenças, visando à comparação com as opiniões emitidas pela população urbana do Município. Foram entrevistados 435 profissionais de saúde ativos (médicos, enfermeiros, auxiliares e atendentes de enfermagem e outros), a maioria do sexo feminino, com idade de 25 a 44 anos. A categoria de atendentes foi a mais numerosa. de modo geral, os cinco últimos sintomas da relação constante do formulário - sangue no escarro, sangramento vaginal, caroço no seio, acessos e sangue na urina, foram considerados menos freqüentes e mais graves, comparativamente aos oito primeiros: falta de ar, febre, fraqueza, dor nas costas, dor no peito, dor de cabeça, tosse e diarréia. Dentre as categorias, os médicos diferenciaram-se atribuindo, com menor freqüência, escores altos para a freqüência e gravidade. Os clínicos valorizaram mais do que os cirurgiões, esses dois fatores, para quase todos os sintomas. O cotejo com a opinião dos leigos entrevistados revelou semelhanças nas tendências, embora tenha havido, por parte destes, maior valorização da freqüência e gravidade.

Estresse no ambiente de trabalho

Stress relates to the broad and generalized body's responses to various environmental, physical and social situations. It is the force that drives the emotions and motives (desires), but is also the cause of the wear and tear of human existence. This study aims to investigate the stressors in administrative technical servers Univ. Estadual Paulista - UNESP, Bauru, as well as on companies providing service within the perimeter of the campus. Was used as a methodology, literature and field research, a questionnaire was applied in order to reach those goals. The profiles of employees who participated in the survey were: both sexes, adults, young people with different educational levels, varying levels of marital and socioeconomic status. The main stressors mentioned by the employees were: workload, dissatisfaction in the workplace, pressure boss or colleagues, as they bring consequences, fatigue or drowsiness, affecting the work environment and mostly family. Physical symptoms of stress are fatigue, difficulty relaxing and headache, and backache. And the psychological symptoms are verbalized concern, agitation, aggression, dissatisfaction, and forgetfulness and feeling of lack of time. It was concluded that these factors negatively affect the quality of life in the work of these employees, interfering with your work, family and socio-emotional life.
