Influence of smoking and obesity on treatment response in patients with axial spondyloarthritis: a systematic literature review.

To assess whether smoking and obesity are predictors of poor treatment response in patients with axial spondyloarthritis (axSpA). A systematic literature review was performed by searching in MEDLINE and EMBASE up to June 2019 with a strategy based on the PICO approach: Population: patients with axSpA; Intervention or exposure: smoking or obesity; Comparison: non-smokers (for smoking) and normal-weight individuals (for obesity); and Outcome: any response criteria currently validated for axSpA. The 2009 Oxford Centre for Evidence-based Medicine levels were used for assessing the studies quality. Out of 1873 references retrieved, 46 studies were selected for full-text review and 12 for data extraction: six stratified patients by smoking and six by obesity. All were longitudinal observational studies, except one, which was cross-sectional. Overall, these studies included 5291 patients (3917 for smoking and 1333 for obesity), and all these patients were on anti-tumor necrosis factor (anti-TNF) therapy. The quality of evidence was graded as level 2b except that from the cross-sectional study which was graded level 4. For smoking, the evidence found is inconsistent: two studies finding negative effects in response to anti-TNF while the other four found no differences in clinical response to this therapy. Regarding obesity, the evidence is more consistent: five of the six studies describing a negative influence in response to anti-TNF. According to the scientific evidence in patients with axSpA, obesity is associated with a more unsatisfactory response to anti-TNF therapy. A poorer response in smokers has yet to be demonstrated. Key Points • Identifying predictors of treatment response in axSpA, especially those that are modifiable, is relevant. • Obesity increases the risk of poorer response to anti-TNF agents in patients with axSpA. • Scientific evidence for smoking habit as a predictor of treatment response in axSpA is inconclusive.

Medición ecográfica del grosor del cartílago femoral en rodilla de jóvenes universitarios sanos / Ultrasound measurement of femoral cartilage thickness in the knee of healthy young university students

ANTECEDENTES Y OBJETIVO: El cartílago articular (CA) siempre está afectado en cualquier articulación con artrosis (A). La ecografía puede ser una herramienta útil en la monitorización de los cambios en el CA. El propósito del presente estudio es medir ecográficamente el grosor del CA en el fémur distal en jóvenes estudiantes y determinar su relación con el índice de masa corporal (IMC), masa muscular, grasa corporal y la práctica deportiva. MATERIALES Y MÉTODOS: Se realizó un estudio transversal observacional con voluntarios sanos, entre 15 y 25 años. Se recogieron datos antropométricos y se midió el grosor del cartílago femoral de la rodilla en cinco puntos. Además, se midió en un subgrupo el porcentaje de músculo y de grasa corporal. RESULTADOS: En el estudio se incluyeron 100 sujetos. La edad promedio fue de 20 años (± 2,5). El IMC promedio fue 23 kg/m2 (± 3,1). El CA tuvo un mayor grosor en los hombres y en los deportistas vs. las mujeres y los sedentarios, con diferencia estadísticamente significativa. Al comparar el IMC con el grosor del CA no se encontró ninguna relación significativa; sin embargo, sólo dos participantes tenían IMC > 30. CONCLUSIONES: El grosor del cartílago tiene una relación directamente proporcional con el porcentaje de músculo, e inversamente proporcional con el porcentaje de grasa. El IMC no es un buen parámetro al evaluar el comportamiento dinámico del cartílago en jóvenes no obesos

BACKGROUND AND OBJECTIVE: Articular cartilage (AC) is always affected in any joint with osteoarthritis. Ultrasound can be a useful tool in monitoring changes in the AC. The purpose of the present study is to ultrasound measure the thickness of the AC in the distal femur in young students and determine its relationship with body mass index (BMI), muscle mass, body fat and sports practice. MATERIALS AND METHODS: An observational cross-sectional study was conducted with healthy volunteers, between 15 and 25 years old. Anthropometric data were collected and the thickness of the femoral cartilage of the knee was measured at 5 points. In addition, the percentage of muscle and body fat was measured in a subgroup. RESULTS: 100 subjects were included in the study. The average age was 20 years (± 2.5). The average BMI was 23 kg/m2 (± 3.1). AC was thicker in men and sportsmen, versus women and sedentary people, with a statistically significant difference. When comparing BMI with AC thickness no significant relationship was found; however, only 2 participants had BMI > 30. CONCLUSIONS: Cartilage thickness has a direct relationship with the percentage of muscle, and inversely with the percentage of fat. BMI is not a good parameter when evaluating the dynamic behaviour of cartilage in non-obese youths

Documento de consenso sobre el uso de la combinación paracetamol/tramadol en pacientes con dolor moderado-intenso / Consensus statement on the use of acetaminophen/tramadol in patients with moderate-severe pain

OBJETIVOS: Desarrollar recomendaciones sobre el uso de la combinación paracetamol/tramadol (P/T) en pacientes con dolor moderado-intenso, basadas en la mejor evidencia y experiencia. MÉTODOS: Se siguió la metodología de grupos nominales y Delphi apoyados por una revisión sistemática de la literatura (RSL). Se seleccionó un panel multidisciplinar de 12 expertos en el manejo del dolor. En la primera reunión de grupo nominal se definió el objetivo, alcance, usuarios, apartados del documento de consenso, así como recomendaciones generales preliminares. Para la RSL se definieron los criterios de inclusión y exclusión, y las estrategias de búsqueda. Dos revisores seleccionaron y analizaron los artículos. Esta evidencia se discutió en una segunda reunión de grupo nominal y se generaron las recomendaciones definitivas. Para cada recomendación, el nivel de evidencia y el grado de recomendación se clasificaron según el modelo de Oxford, y el grado de acuerdo por técnica Delphi. Se definió acuerdo si al menos el 70% de los participantes contestaron ≥ 7 en cada recomendación (1 = total desacuerdo a 10 = total acuerdo). RESULTADOS: Se generaron 20 recomendaciones que cubren aspectos generales, como la evaluación del dolor, y específicos del manejo de P/T. Estos últimos abarcan la indicación de la combinación P/T (perfil de paciente, dosificación, pauta, formulaciones), gestión del riesgo (contraindicaciones, precauciones, interacciones, uso concomitante con otras medicaciones, seguimiento, situaciones especiales) y la educación del paciente. CONCLUSIONES: Estas recomendaciones pretenden resolver algunos interrogantes clínicos habituales y facilitar la toma de decisiones respecto al uso de la combinación P/T en pacientes con dolor moderado-intenso

OBJECTIVES: To present recommendations on the use of the paracetamol/tramadol (P/T) combination in patients with moderate-intense pain based on best evidence and experience. METHODS: The method of nominal groups and Delphi was followed, and supported by a systematic literature review (SLR). A multidisciplinary panel of 12 experts in pain management was selected. In the first nominal group meeting, the aim, scope, users, and sections of the consensus document, were defined, along with the preliminary general recommendations. For the SLR, the inclusion and exclusion criteria, as well as the search strategies, were defined. Two reviewers selected and analysed the articles. This evidence was discussed in a second nominal group meeting, and definitive recommendations were developed. For each recommendation, the evidence levels and grade of recommendation grades were classified according to the Oxford model, and the grade according to the Delphi technique. It was defined as an agreement if at least 70% of the participants scored ≥ 7 for each recommendation (1 = total disagreement to 10 = total agreement). RESULTS: A total of 20 recommendations were produced, which covered general aspects, such as the assessment of pain, and those specific to P/T management. These latter included the indications of the P/T combination (patient profile, dosing, prescription, formulations), risk management (contraindications, precautions, interactions, concomitant use with other medications, follow-up, special situations), and patient education. CONCLUSIONS: These recommendations attempt to resolve any of the routine clinical questions, and help in the making of decisions on the use of the P/T combination in patients with moderate-intense pain

Prevalencia de la afección musculoesquelética no traumática como motivo de consulta y su impacto asistencial en un servicio de urgencias / Prevalence of non-traumatic musculoskeletal pathology as main complaint and its impact in a emergency department

Introducción. La afección musculoesquelética atraumática (AMA) genera gran carga asistencial en los servicios sanitarios a nivel de atención primaria, sin embargo, son escasos los estudios europeos diseñados para determinar su proporción dentro de los servicios de urgencias. Nuestro objetivo es determinar la prevalencia de AMA y su impacto asistencial y administrativo en el funcionamiento del servicio de urgencias de un hospital universitario de Madrid. Material y método. Se revisaron 2.000 historias clínicas electrónicas aleatorizadas entre 2008-2010. Se recogieron los motivos de consulta, el tiempo consumido hasta el alta desde la primera valoración, la demanda de pruebas de imagen y la necesidad de nuevas valoraciones antes de trascurrido el primer mes de la valoración inicial. Resultados. La prevalencia de AMA fue del 13,8% IC 95% (12,1-15,4%) de todos los pacientes. El motivo más frecuente de consulta fue la lumbalgia. De todos los casos de AMA valorados, en el 79,1% se solicitó una prueba de imagen. Los pacientes con AMA consumieron una media de 79 min y un 17% de los pacientes consultaron por el mismo motivo en menos de 30 días. Conclusiones. Los resultados del presente estudio ubican a la AMA en el primer lugar de los motivos de consulta urgente en nuestro medio, generando el más alto consumo de tiempo y la mayor frecuencia de consultas nuevas por el mismo motivo en menos de un mes. La falta de formación médica en el manejo de este tipo de afecciones puede ser causa de este fenómeno. Durante el diseño de líneas estratégicas para optimizar la atención en los servicios de urgencias se debe tener en cuenta la importancia de este tipo de procesos patológicos (AU)

Background. Non-traumatic musculoskeletal pathology (NTMP) generates a high healthcare demand in primary care, however, European studies designed to assess its real impact in Emergency Departments are scarce. The present study aims to determine the prevalence of NTMP and its impact in Emergency Department of a university hospital in Madrid. Material and method. Two thousand randomized medical registries were reviewed from 2008 to 2011. The epidemiological data collected were, main complaints, time consumed, image test requests, and need of further assessment within a month. Results. Prevalence of NTMP was 13.8% (95% CI; 12.1%-15.4%) of all patients. The most frequent musculoskeletal complaint was lumbar pain. An imaging test was requested in 79.1% of all the NTMP cases assessed. Patients with NTMP consumed an average of 79 minutes, with 17% of them requesting a new urgent assessment within the first month. Conclusions. The results of this study show that NTMP is the leading cause for emergency department visits in our area, producing the highest consumption of time and the highest frequency of new queries for the same reason within a month. The overuse of the emergency services and the lack of medical training in the management of this type of pathology can cause this phenomenon. During the design of strategies to optimize patients care in emergency departments, the importance of this type of pathology should be taken into account (AU)

Comparison of prevalence of synovitis by ultrasound assessment in subjects exposed or not to self-reported physical overexertion: the Monday's synovitis.

OBJECTIVE: To compare the proportion of synovitis detected by ultrasonographic study (USS) of the hands, in subjects with no rheumatologic known disease according to self-reported level of overexertion performed the day before. METHODS: 407 consecutive volunteers were enrolled in a twelve-month period and underwent an ultrasound assessment of the hand. All studies were performed on Monday or Friday. Subjects were grouped according to their self-reported overexertion carried out the day before. Presence or absence of ultrasonographic findings compatible with synovitis was compared between groups. RESULTS: 95.8% of those tested on Friday had made no overexertion the day before the study, while 30.2% of those assessed on Monday declared to have carried out an overexertion. Presence of carpal synovial hypertrophy, synovial fluid/effusion, and power-Doppler signal was statistically higher in subjects who carried out an overexertion the day before the study than the rest of subjects when the dominant hand was assessed. Globally, presence of any synovitis ultrasonographic finding was statistically higher in subjects who were studied on Monday than Friday (34.9% versus 12.1%) and in subjects who self-reported an overexertion the day before compared to the rest of subjects (47.7 versus 11.5%). CONCLUSIONS: In general, we recommend performing the USS as many days as possible after the most recent overexertion.

Fatal outcome in a case of dermatomyositis and Hamman-Rich syndrome.

We present the fatal outcome in a 31-year-old woman of Latin-American origin diagnosed with dermatomyositis. There were three months between death and the onset of symptoms. The initial presentation was normal dermatological symptoms to which were shortly added clinical signs of effects on the lungs, as was shown radiologically and through pulmonary function tests which were subsequently identified histologically as Hamman-Rich syndrome. The patient was treated with high doses of corticosteroids, intravenous (IV) immunoglobulin, cyclophosphamide and cyclosporin. We carried out a review of the literature on pulmonary compromise in dermatomyositis, clinical and anatomopathological forms and treatment alternatives.
