Active methods in electricity and magnetism courses: Influence of degree, academic level and gender on student performance.

The performance of first-year students in electromagnetism (E&M) courses of different engineering degrees at a Spanish public university was measured using the Brief Electricity and Magnetism Assessment (BEMA), a standard research-based instrument to assess students' understanding after attending introductory courses in electricity and magnetism. In all cases, Flipped classroom (FC) built on information and communications technology was used. The objective of this paper is to analyse if the gain in the BEMA pre and post-test results is influenced by several factors such as the degree, the students' academic grade, and gender. Moreover, as some studies have shown that the students' retention of the concepts was significantly stronger in active learning than in traditional approaches, a third BEMA test was performed by the students to analyse the long-term retention gain dependence on the same factors. Students from different engineering degree programs were asked to complete two BEMA tests during the course and a third one after a few months. ANOVA tests were used to analyse the existence of significant differences in gain between student degree programs, student academic level and student gender. Results have shown no differences in the BEMA performance by degree program, but significant differences were found by academic level and gender. Retention did not depend on the degree course but on the academic level. Mean gain value by academic level, and gender was obtained and concluded that the best students presented the best gain results and that gain depends on the students' gender: males outperformed females in the BEMA tests, although there were no significant differences in the course grades. It is thus necessary to understand these differences and to implement measures in daily teaching work to improve women's performance.

Safety and efficacy of intra-arterial bone marrow mononuclear cell transplantation in patients with acute ischaemic stroke in Spain (IBIS trial): a phase 2, randomised, open-label, standard-of-care controlled, multicentre trial.

BACKGROUND: Pilot clinical trials have shown the safety of intra-arterial bone marrow mononuclear cells (BMMNCs) in stroke. However, the efficacy of different doses of intra-arterial BMMNCs in patients with acute stroke has not been tested in a randomised clinical trial. We aimed to show safety and efficacy of two different doses of autologous intra-arterial BMMNC transplantation in patients with acute stroke. METHODS: The IBIS trial was a multicentre phase 2, randomised, controlled, investigator-initiated, assessor-blinded, clinical trial, in four stroke centres in Spain. We included patients (aged 18-80 years) with a non-lacunar, middle cerebral artery ischaemic stroke within 1-7 days from stroke onset and with a National Institutes of Health Stroke Scale score of 6-20. We randomly assigned patients (2:1:1) with a computer-generated randomisation sequence to standard of care (control group) or intra-arterial injection of autologous BMMNCs at one of two different doses (2 × 106 BMMNCs/kg or 5 × 106 BMMNCs/kg). The primary efficacy outcome was the proportion of patients with modified Rankin Scale scores of 0-2 at 180 days in the intention-to-treat population, comparing each BMMNC dose group and the pooled BMMNC group versus the control group. The primary safety endpoint was the proportion of serious adverse events. This trial was registered at ClinicalTrials.gov, NCT02178657 and is completed. FINDINGS: Between April 1, 2015, and May 20, 2021, we assessed 114 patients for eligibility. We randomly assigned 77 (68%) patients: 38 (49%) to the control group, 20 (26%) to the low-dose BMMNC group, and 19 (25%) the high-dose BMMNC group. The mean age of participants was 62·4 years (SD 12·7), 46 (60%) were men, 31 (40%) were women, all were White, and 63 (82%) received thrombectomy. The median NIHSS score before randomisation was 12 (IQR 9-15), with intra-arterial BMMNC injection done a median of 6 days (4-7) after stroke onset. The primary efficacy outcome occurred in 14 (39%) patients in the control group versus ten (50%) in the low-dose group (adjusted odds ratio 2·08 [95% CI 0·55-7·85]; p=0·28), eight (44%) in the high-dose group (1·89 [0·52-6·96]; p=0·33), and 18 (47%) in the pooled BMMNC group (2·22 [0·72-6·85]; p=0·16). We found no differences in the proportion of patients who had adverse events or dose-related events, but two patients had a groin haematoma after cell injection in the low-dose BMMNC group. INTERPRETATION: Intra-arterial BMMNCs were safe in patients with acute ischaemic stroke, but we found no significant improvement at 180 days on the mRS. Further clinical trials are warranted to investigate whether improvements might be possible at different timepoints.

Crafting urban equality through grassroots critical pedagogies: weave, sentipensar, mobilize, reverberate, emancipate.

How do ordinary citizens, activists and urban practitioners learn to become agents of change for a socially just habitat? The paper explores this question through the experiences of eight grassroots schools of popular urbanism working under the umbrella of the Habitat International Coalition (HIC) in Latin America. Building on a process of self-documentation and collective pedagogic reflection driven by the protagonists of these schools, the analysis explores the core pedagogic practices identified across the schools to enact popular urbanism as a collective and intentional praxis: to weave, sentipensar, mobilize, reverberate and emancipate. We argue that, put in motion, these pedagogic practices transgress the rules and boundaries of the formal classroom, taking participants to and through other sites and modes of learning that host significant potential to stimulate collectivizing and alternative ways of seeking change towards urban equality.

The antecedents of entrepreneurial behaviour in the creation of platform economy initiatives: An analysis based on the decomposed theory of planned behaviour.

The platform economy (PE) has experienced its strongest period of growth since the emergence of the sharing economy (SE). Much work has been put into understanding the effects and antecedents of the PE, with particular emphasis on peers and consumer motivation, yet few studies have analysed the motivations of the service providers and even fewer its impact on individual and collective wellbeing. The aim of this paper is provide a better understanding of the decomposed beliefs that inform the attitudinal, social-normative and control factors that make up pro-PE behavioural intention (the intention to develop a PE initiative) in the context of digitisation and wellbeing, while making the platform the focus of analysis. In this study we adapt and extend the Decomposed Theory of Planned Behaviour (DTPB) and use partial least squares regression (PLS), a structural equation modelling technique, to analyse valid data collected from 127 PE organisations operating in Spain. The empirical results obtained demonstrate that the three antecedents for behavioural intention (perceived control, attitude and the subjective norm) have a positive effect on the intention to develop a PE initiative. The study also shows that PE micro-entrepreneurs are motivated by individual and collective wellbeing and not just financial gain. This contributes substantially to reconciling the PE with its origins, rooted in pro-solidarity and social concerns, and to framing wellbeing in a broader paradigm consisting of psychological and social factors, going beyond the economic considerations and interests contained in previous paradigms.

Tratamiento de la hepatitis C en el conurbano de Buenos Aires / Hepatitis C treatment in the surrounding area of Buenos Aires

Resumen La principal infección viral transmisible por sangre es actualmente la debida al virus de hepatitis C (VHC). Uno de los mayores obstáculos para el logro de su control en la Argentina se relaciona con las dificultades de acceso al diagnóstico y tratamiento oportuno de las personas infectadas. Este estudio se realizó con el objetivo de caracterizar a los pacientes infectados con VHC que iniciaron tratamiento con antivirales de acción directa (AAD) y describir la experiencia vinculada al tratamiento. Se seleccionaron las historias clínicas de 82 pacientes, 44 (53.7%) de sexo masculino, 37 (45.1%) de sexo femenino, y uno (1.2%) transgénero. La media de edad fue de 49 años. Se halló una frecuencia de cirrosis de 39%, 32 pacientes, coinfección con HIV en 48 (58.5%) y con VHB en 27 (32.9%). En 52 (63.4%) no se observó ningún factor de riesgo claramente asociado a infección. Todos completaron la terapia, de ellos 72 (87.8%) efectuaron el control para confirmar respuesta viral sostenida (RVS), que fue de 98.6%. Concluimos que el testeo universal debe implementarse por sobre el testeo con enfoque de riesgo, y que debe promoverse un criterio de atención simplificado y descentralizado, reservando la atención especializada para pacientes con cirrosis descompensada y cáncer de hígado.

Abstract Hepatitis C virus (HCV) infection is currently the main blood-borne viral infection. One of the main obstacles to achieving its control in Argentina is related to difficulties in accessing the diagnosis and timely treatment of infected people. We carried out this study with the aim of characterizing the HCV-infected patients who started treatment with direct-acting antivirals (DAAs) and to describe the experience related to treatment. The medical records of 82 patients, 44 (53.7%) male, 37 (45.1%) female, and one (1.2%) transgender, were selected. The mean age was 49 years. We report a frequency of cirrhosis, 39%, in 32 patients, coinfection with HIV in 48 (58.5%) and with HBV in 27 (32.9%). In 52 patients (63.4%), no risk factor clearly associated with infection was observed. All completed the therapy, of them 72 (87.8%) carried out the control to confirm sustained viral response (SVR), that attained 98.6%. We conclude that universal testing should be implemented over testing based on a risk approach, and that a simplified and decentralized care criterion should be promoted, reserving specialized care for patients with decompensated cirrhosis and liver cancer.

Is Thought Management a Resource for Functioning in Women with Fibromyalgia Irrespective of Pain Levels?

OBJECTIVE: This study aimed to examine the relationship between cognitive factors (cognitive fusion and catastrophizing) and functional limitation experienced by patients with fibromyalgia across different levels of pain severity (i.e., moderation). METHODS: The sample comprised 226 women with fibromyalgia. Their mean age was 56.91 years (standard deviation = 8.94; range = 30 to 78 years). RESULTS: Pain severity, cognitive fusion, and all components of catastrophizing (i.e., rumination, magnification, and helplessness) contributed to greater fibromyalgia impact on functioning in the multivariate analyses (all P < 0.001). A moderation effect was also found in the relationship between cognitive fusion and fibromyalgia impact on functioning (B = -0.12, t = -2.42, P = 0.016, 95% confidence interval: -0.22 to -0.02) and between magnification and fibromyalgia impact (B = -0.37, t = -2.21, P = 0.028, 95% confidence interval: -0.69 to -0.04). This moderation was not observed for rumination and helplessness. CONCLUSIONS: The results suggest that in interventions to improve functioning in people with fibromyalgia, some maladaptive forms of thought management (i.e., cognitive fusion and magnification) preferably should be challenged at milder levels of pain severity. According to our findings, cognitive fusion and magnification might have less room to impact functioning at higher levels of pain severity; therefore, rumination and helplessness, which had comparable associations with functioning irrespective of pain levels, would be preferable targets in psychological interventions in patients with fibromyalgia experiencing more severe pain levels.

Palliative Sedation in Patients Hospitalized in Internal Medicine Departments.

CONTEXT: Palliative sedation is used to relieve end-of-life refractory symptoms. OBJECTIVE: The objective of this study was to describe the use of palliative sedation in patients who die in internal medicine departments. METHODS: An observational, cross-sectional, retrospective, and multicenter clinical audit study was conducted in 145 hospitals in Spain and Argentina. Each hospital included the first 10 patients who died in the internal medicine department, starting on December 1, 2015. RESULTS: We included 1447 patients, and palliative sedation was administered to 701 patients (48.4%). Having a terminal illness (odds ratio [OR] 2.469, 95% CI 1.971-3.093, P < 0.001) and the length of hospital stay (OR 1.011, 95% CI 1.002-1.021, P = 0.017) were independently associated with the use of palliative sedation. Consent was granted by the families of 582 (83%) patients. The most common refractory symptom was dyspnea, and the most commonly used drugs for sedation were midazolam (77%) and morphine (89.7%). An induction dose was administered in 25.7% of the patients. Rescue doses were scheduled for 70% of the patients, and hydration was maintained in 49.5%. Pain was more common in patients with cancer, whereas dyspnea was more common in those without cancer. Rescue doses were used more often for the patients with cancer (77.8% vs. 67.7%, P = 0.015). Monitoring the palliative sedation with a scale was more frequent in the patients with cancer (23.7% vs. 14.3%, P = 0.008). CONCLUSIONS: Palliative sedation is used more often for terminal patients. There are differences in the administration of palliative sedation between patients with and without cancer.

Interrelación entre enfisema y disfunción diastólica ventricular izquierda: nuestra experiencia en el Hospital Privado Centro Médico de Córdoba / Interrelation between emphysema and diastolic dysfunction left ventricular: our experience in the Hospital Private Medical Center of Córdoba

Introducción: Las consecuencias hemodinámicas de la hiperinflación y el enfisema se producen por compresión cardíaca debido a elevadas presiones intratorácicas, lo que produciría disfunción diastólica ventricular izquierda subclínica. Nuestro objetivo es correlacionar el porcentaje de enfisema con parámetros de función pulmonar y con el tamaño de las cámaras cardíacas, función sistólica ventricular global y función diastólica ventricular izquierda, en la enfermedad pulmonar obstructiva crónica. Materiales y Métodos: participaron pacientes con enfermedad pulmonar obstructiva crónica moderada y severa asistidos en un Servicio de Neumonología del Hospital Privado Centro Médico de Córdoba, desde el 01 de enero al 31 de octubre de 2014. Se cuantificó el volumen y porcentaje de enfisema por tomografía computada de alta resolución, se realizaron espirometría, prueba de marcha de seis minutos, determinación de volúmenes pulmonares y ecocardiograma Doppler color. Resultados: Se encontró correlación negativa y significativa del porcentaje de enfisema con el porcentaje del valor teórico del VEF1 postbroncodilatador (p = 0.005) y el cociente VEF1/CVF postbroncodilatador (p = 0.004) y; además, entre el cociente VEF1/CVF postbroncodilatador y el volumen del enfisema en cm3 (p = 0.000). De un subgrupo de 20 pacientes. Siete pacientes (35%) presentaron diagnóstico de disfunción diastólica ventricular izquierda de grado I. Se encontraron correlaciones negativas pero no significativas entre el porcentaje de enfisema con función sistólica ventricular global y el tamaño de las cámaras cardíacas. Conclusiones: Se destaca la utilidad del ecocardiograma para reducir el sub diagnóstico de disfunción diastólica ventricular izquierda. Se destaca la importancia que tendrían la hiperinflación y el enfisema en el deterioro del patrón de llenado diastólico ventricular izquierdo y en la reducción del tamaño de las cámaras cardíacas con disminución en la tolerancia al ejercicio.

Interrelationship between Emphysema and Left Ventricular Diastolic Dysfunction: our experience in the Hospital Privado Centro Médico de Córdoba

Introduction: The hemodynamic consequences of hyperinflation and emphysema are produced by cardiac compression due to high intrathoracic pressures, which could produce subclinical left ventricular diastolic dysfunction. Our purpose is to correlate the percentage of emphysema with lung function parameters and cardiac chamber sizes, the global ventricular systolic function and the left ventricular diastolic function, in cases of chronic obstructive pulmonary disease. Materials and Methods: The participants were patients with moderate and severe chronic obstructive pulmonary disease treated in the Pulmonology Service of the Hospital Privado Centro Médico de Córdoba from January 1st to October 13th, 2014. We quantified the volume and percentage of emphysema by high resolution computed tomography and carried out a spirometry, a Six Minute Walk Test, measurement of pulmonary volumes and color Doppler echocardiography. Results: We found a significant negative correlation between the percentage of emphysema and the percentage of the post-bronchodilator FEV1 theoretical value (p = 0.005) and the post-bronchodilator FEV1/FVC (Forced Expiratory Volume in First Second/Forced Vital Capacity) quotient (p = 0.004), and, also, between the post-bronchodilator FEV1/FVC quotient and the emphysema volume in cm3 (p = 0.000). Out of a sub-group of 20 patients, seven patients (35%) were diagnosed with grade I left ventricular diastolic dysfunction. We found negative, but not significant correlations between the percentage of emphysema and global ventricular systolic function and cardiac chamber sizes. Conclusions: We should emphasize the usefulness of the echocardiography in reducing sub-diagnoses of left ventricular diastolic dysfunction. We should also stress on the importance hyperinflation and emphysema would have in the impairment of the left ventricular diastolic filling pattern and in the decrease in cardiac chamber sizes, with a decrease in exercise tolerance.

La imitación y el entonamiento afectivo en el juego social temprano / Imitation and affect attunement in early social play

Con el objetivo de estudiar las pautas adultas de imitación y entonamiento afectivo que ocurren en las situaciones de juego social temprano entre adulto y bebé, se realizó un estudio longitudinal de caso único, con una díada adulto-bebé. La edad del bebé en la primera sesión, según la convención piagetiana [año; mes (día)], fue: 00; 3 (05) y en la última sesión: 00; 6 (28). Se filmaron 8 sesiones de interacción espontánea de la díada, en su hogar, cada 15 días. De cada sesión se seleccionaron los primeros 10 minutos de juego social temprano. Con este material se generó una video-secuencia de juego social temprano a la que se le aplicó un código observacional con categorías para las pautas de actividades de coincidencia maternas (imitación y entonamiento afectivo). Los datos obtenidos en este estudio indican que las actividades de coincidencia maternas de imitación y entonamiento afectivo aparecen en todo el período estudiado, con una frecuencia de dos eventos de coincidencia por minuto de juego social temprano. Se observó que las pautas de entonamiento afectivo materno casi duplican a las de imitación entre los 3 y 6 meses de vida del bebé. Asimismo, se registró que la mayoría de los entonamientos afectivos fueron transmodales y que la madre utilizó su voz como modalidad conductual privilegiada para establecer coincidencias comportamentales con su bebé, ya sea a través de la imitación o del entonamiento. Las imitaciones maternas más frecuentes ocurrieron como respuesta a las vocalizaciones del bebé y los entonamientos afectivos fueron provocados principalmente por los movimientos del bebé.

This paper focuses on two specific matching activities of maternal behavior in early social play: imitation and affect attunement. Imitationis a pattern of frequent interaction between adult and baby, providing a pleasant experience to both participants. In that context, imitation is not only bi-directional, but it is the adult who imitates more frequently. Affect attunement is an intuitive and fleeting interaction pattern, through which the adult attunes to the baby's affective state. It is a matching activity, where the amodal features of the infant's behavior (intensity, temporal organization, spatial pattern and / or quantity) are reflected through a different conduct. Previous research indicates that during the first 6 months of the baby's life, the adult very often uses imitation as well as affect attunement for interacting (which involves performing a different behavior than the baby's in which the adult matches the intensity, temporal pattern, spatial pattern, and / or the amount of the child's original behavior). Maternal affect attunement events have been observed from 2 months of age, and the frequency ratio between affect attunement and maternal imitation has been observed to change in ontogenetic development: between the baby's 2nd and 6th months the adult's imitative activity occurs at higher rates; while in the second half of the first year of life, the relationship is reversed. This paper presents the results of a longitudinal case study on a mother-infant dyad, about maternal imitation and affect attunement behaviors in early social play situations between the 3rd and 6th months of the baby's life. According to Piaget's convention [year; month (day)], the baby's age was 00; 3(05) in the first session, and 00; 6 (28) in the last session. Every 15 days, a total of 8 sessions of the dyad's spontaneous interaction, were filmed in their home. From each session, the first 10 minutes of early social play were selected. With this material a video-sequence of early social play was generated to which an observational code with categories for maternal matching activity patterns (imitation and affect attunement) was applied. The percentage of each category's occurrence in each evolutionary period was calculated. The data obtained in this study indicate that maternal matching activities of imitation and affect attunement appear from the beginning of the studied period. These results confirm those previously obtained in other studies that show the early emergence of adult imitation and affect attunement behavioral patterns. The data also indicate that matching activities of imitation and affect attunement appear throughout the studied period with a frequency of two events perminute of early social play. These results partially confirm those previously obtained in other studies. The new information obtained in our study concerns the frequency of both reciprocity patterns, and the type of behavior of the mother and baby involved in these matching activities. Patterns of maternal affect attunement almost double those of imitation between the baby's 3rd and 6th months. It was also reported that most affect attunements were transmodal and that the mother used her voice as a privileged way to establish a behavioral match with her baby, either through imitation or affect attunement. The most frequent maternal imitations occurred in response to the baby's vocalizations, and affect attunements were caused mainly by the baby's movements. Without detracting from the dyad's intense vocal activity already registered in the field's literature, the high frequency of affect attunements in response to infant movement highlights a trait less noticed in previous research: the adult's mastery in reading the baby's body and movement.

Multimodal Study of Adult-Infant Interaction: A Review of Its Origins and Its Current Status / Estudo Multimodal da Interação Adulto-Criança: Uma Revisão de Suas Origens e Seu Status Atual / Estudio Multimodal de las Interacciones Adulto-Bebé: Una Revisión Sobre Sus Orígenes y Su Estado Actual

Abstract An interpretative review of research on adult-infant interactions involving the analysis of movement behaviors is presented, systematically linking previous studies to current research on the subject. Forty-two articles analyzing the dyad's interactive movement in the period 1970-2015 were found. Twelve papers were excluded, including only those that studied the phenomenon in the baby's first year of life. The results revealed that movement was a central topic in early interaction studies in the 70s. In the 1980's and 1990's, its study was marginal and it is currently resurging under the embodiment perspective. The conceptual framework and research methods used in the pioneering work are presented, and the thematic foci shared with current research are highlighted. Thus, essential keys are provided for the updated study of early interactions from a multimodal perspective.(AU)

Adherence to guidelines and mortality in atrial fibrillation.

OBJECTIVE: Determining the adherence to ACC/AHA/ESC 2006 guidelines and its influence on the survival of patients with atrial fibrillation. METHODS: Prospective observational study of patients discharged during 2007 from an Internal Medicine department with a main or secondary diagnose of atrial fibrillation. The stroke risk was estimated with the CHADS2 score. The follow-up was carried out in outpatient medical office or via telephone. RESULTS: We included 259 patients (mean age 80.9 years); 73% of them had a high risk of stroke. Oral anticoagulants were administered to 134 (51.7%), and antiplatelet drugs to 71 (27%) patients. A rate control strategy was chosen for 155 (59.8%) patients and a rhythm control one for 28 (10.8%). In 100 (38.6%) patients, treatment was adherent to the guidelines. Adherence to the guidelines was associated with age (0.95 95%CI 0.92-0.99; p=0.03), contraindication to the use of oral anticoagulants (0.38 95%CI 0.18-0.81; p=0.01) and mitral valve heart disease/valvular prosthesis (2.10 95%CI 1.04-4.25; p=0.04). The median follow-up was 727 days, and 191 patients died. Patients treated according to the guidelines had a higher rate of survival during the first three years (0.47 vs. 0.36; p=0.049). The use of oral anticoagulants was associated with a higher probability of survival over a 5 year period (0.34 vs 0.21; p=0.001) and the rate control strategy during the first year (0.69 vs 0.57; p=0.04). CONCLUSIONS: In the real world, the treatment of atrial fibrillation according to the guidelines is associated with improved survival for up to three years during follow-up.

Los exámenes de salud son una herramienta útil en la detección de factores predictivos de padecer dolor lumbar / Health tests are a useful tool in the detection of predictive factors of back pain

Objetivo: Determinar si los Exámenes de Salud que se realizan a los trabajadores expuestos a manipulación manual de cargas (MMC) y posturas forzadas (PF) de un hospital general, dentro de las actividades de la Vigilancia de la Salud individual, son una herramienta útil en la detección de factores predictivos de padecer dolor lumbar. Método: Estudio descriptivo sobre una muestra, obtenida aleatoriamente de un listado ordenado alfabéticamente, de 114 trabajadores con una antigüedad en el puesto de trabajo mayor de 1 año. Se les realizó un examen de salud en el que se incluyen como variables independientes del estudio el sexo, la edad, el puesto de trabajo actual, la antigüedad en el mismo, el tipo de jornada, los turnos, IMC, actividad física, antecedentes de depresión, antecedentes de dolor lumbar, el tipo de convivencia, las actividades extra laborales, la historia laboral, el tabaquismo, factores personales y familiares y la exploración física. Y como variable dependiente haber padecido dolor lumbar en el último año. Mediante cuestionario autoadministrado se recogieron los aspectos relacionados con las condiciones de trabajo y ambiente psicosocial según el modelo de demandacontrol/ apoyo social de Karasek y Johnson. Se realizó un análisis descriptivo, bivariante y multivariante de los datos obtenidos. Resultados: La incidencia de dolor lumbar fue de13,3 % (I.C.95 %6,639-30,147). Sólo la edad (>52 años), el sexo femenino y la exploración anormal se relacionan con la aparición de dolor lumbar en el estudio bivariante. La asociación de las variables edad y exploración física anormal justifican el 86% de los casos de dolor lumbar. Conclusiones: A tenor de los resultados podría concluirse que son factores predictivos de padecer dolor lumbar el tener más de 52 años y que la exploración física de la columna vertebral sea anorma (AU)

Objective: To determine whether Health Screenings performed on workers exposed to heavy handling and awkward postures in a general hospital as a part of the activities related to individual Health Surveillance, are useful as a tool in detecting predictors of developing Low Back Pain (LBP). Methods: Descriptive study on a sample of 114 workers with a period of service of work longer than 1 year. All subjects underwent a health examination where the variables gender, age, current job, seniority, type of day-shift, Body Mass Index (BMI), physical activity, history of depression, history of LBP, type of coexistence, non-work related activities, work history, smoking, personal and family factors and physical examination were included as independent variables. The dependent variable was to have had back pain in the past year. Aspects of working conditions and psychosocial environment modeled on social demanda-control/apoyo Karasek and Johnson were collected through self-administered questionnaires. A descriptive, bivariate and multivariate analysis was performed. Results: Incidence of LBP was DE13 , 3% ( 95% CI 6.639 to 20.147 ) Only age , female gender and abnormal exploration was associated with the development of LBP. The association of the variables age and abnormal physical examination justify the 86 % of cases of LBP. Conclusions: On the basis of these results we conclude that having more than 52 years and an abnormal physical examination of the spine are predictive factors for developing LBP (AU)
