Extraintestinal Manifestations of Inflammatory Bowel Disease.

Extraintestinal manifestations (EIM) in inflammatory bowel disease (IBD) are frequent and may occur before or after IBD diagnosis. EIM may impact the quality of life for patients with IBD significantly requiring specific treatment depending on the affected organ(s). They most frequently affect joints, skin, or eyes, but can also less frequently involve other organs such as liver, lungs, or pancreas. Certain EIM, such as peripheral arthritis, oral aphthous ulcers, episcleritis, or erythema nodosum, are frequently associated with active intestinal inflammation and usually improve by treatment of the intestinal activity. Other EIM, such as uveitis or ankylosing spondylitis, usually occur independent of intestinal inflammatory activity. For other not so rare EIM, such as pyoderma gangrenosum and primary sclerosing cholangitis, the association with the activity of the underlying IBD is unclear. Successful therapy of EIM is essential for improving quality of life of patients with IBD. Besides other options, tumor necrosis factor antibody therapy is an important therapy for EIM in patients with IBD.

Do blood components affect the production of reactive oxygen species (ROS) by equine synovial cells in vitro?

Blood-derived products are commonly administered to horses and humans to treat many musculoskeletal diseases, due to their potential antioxidant and anti-inflammatory effects. Nevertheless, antioxidant effects have never been shown upon horse synovial fluid cells in vitro. If proved, this could give a new perspective to justify the clinical application of blood-derived products. The aim of the present study was to investigate the antioxidant effects of two blood-derived products - plasma (unconditioned blood product - UBP) and a commercial blood preparation (conditioned blood product - CBP)¹ - upon stimulated equine synovial fluid cells. Healthy tarsocrural joints (60) were tapped to obtain synovial fluid cells; these cells were pooled, processed, stimulated with lipopolysaccharide (LPS) or phorbol 12-myristate 13-acetate (PMA), and evaluated by flow cytometry for the production of reactive oxygen species (ROS). Upon addition of any blood-derived product here used - UBP and CBP - there was a significant decrease in the oxidative burst of synovial fluid cells (P<0.05). There was no difference between UBP and CBP effects. In conclusion, treatment of stimulated equine synovial cells with either UBP or CBP efficiently restored their redox equilibrium.

Grado de pérdida de capacidad laboral asociada a la comorbilidad de los desórdenes músculo esqueléticos en la junta de calificación de invalidez regional Huila, 2009-2012

Resumen: Los desórdenes músculo esqueléticos son entidades que generan un efecto en la salud relacionados con la calidad de vida, dado al impacto global en la condición física, el bienestar psicológico y funcional. Estas entidades generan un gran número de indemnizaciones y en algunas oportunidades según el grado de pérdida de capacidad laboral la invalidez. Objetivo: Determinar la asociación del grado de perdida de la capacidad laboral con la comorbilidad de los desórdenes músculo esqueléticos y otros factores asociados. Materiales y métodos: Se realizó un estudio de corte transversal, basado en registros e historias clínicas. Los registros iniciales fueron 1427 casos, de los cuales 513 presentaban diagnóstico de DME y de estos 240 solicitaron la pérdida de capacidad laboral a la junta de invalidez regional Huila en el periodo comprendido del 2009 al 2012. Resultados: La distribución del grado de la pérdida de capacidad laboral generada de los DME por incapacidad permanente parcial fue del 73,3% y por invalidez el 26,7%. Se encontró una asociación significativa con respecto a la edad (p=0,002), donde el rango de 50-65 años presento mayor pérdida de capacidad laboral; con el género (p=0,047), siendo el femenino más prevalente la invalidez (34,7%) que en el masculino (23,2%) y la comorbilidad (p=0,019), donde los desórdenes músculo esqueléticos y los trastornos depresivos generaron mayor pérdida de capacidad laboral. No se encontró asociación significativa con la escolaridad (p=0,167), oficio (p=0,442) y actividad económica (p=0,118). En el análisis multivariado se encontró asociación significativa con el origen común (OR=4.028, IC 95%: 2.010, 8.072), el sexo femenino (OR=2.565, IC 95%: 1.140, 5.771), y el nivel de escolaridad técnico (OR=12.208, IC 95%: 1.372, 108.634). Conclusiones: La comorbilidad generó mayor pérdida de capacidad laboral, aunque los factores que en conjunto mostraron asociación fueron la edad avanzada, el género femenino, el origen común y el menor nivel educativo.

Caracterización del ausentismo por incapacidad médica en los trabajadores administrativos de una empresa de salud

Se realizó un estudio descriptivo de corte transversal a partir de la base de datos de ausentismo por incapacidad médica del área administrativa de una empresa de salud con sede en Bogotá durante el primer semestre de 2014 Objetivo: Caracterizar las principales causas de ausentismo laboral en los funcionarios administrativos de una empresa de salud desde la revisión de una base de datos para plantear recomendaciones de prevención. Métodos: Mediante un estudio descriptivo de corte transversal se analizó a un grupo de 284 trabajadores administrativos de una empresa de salud que reportaron ausentismo por incapacidad médica en el primer semestre de 2014. Resultados: Las principales causas de ausentismo laboral en el personal administrativo para el primer periodo de 2014 fueron por enfermedad general la diarrea y gastroenteritis (22,2%) y la rinofaringitis aguda (4,4%), y por enfermedad laboral los trastornos osteomusculares (1,04%). El 72% (207) de las incapacidades se generaron en trabajadores administrativos del género femenino y el 46.3% (133) en el grupo etáreo comprendido entre los 31-40 años; según la antigüedad laboral las personas que tienen entre 1 y 10 años generaron el 59.2% de los eventos. Conclusión: Las incapacidades en la población de estudio están dadas en mayor porcentaje por incapacidad general, por enfermedades infectocontagiosas y osteomusculares. Teniendo en cuenta que el presente estudio es netamente descriptivo, puede servir como punto de partida para futuros estudios en los que pueda medirse relación causal entre tipo de incapacidad, duración, género, cargo y grupo etáreo.

Conclusión: Se encontró una alta exigencia mental, temporal y esfuerzo en los trabajadores y una relación significativa entre la profesión con la percepción de exigencia física, predominando en los técnicos, seguidos de abogados e ingenieros y entre el área de trabajo con la percepción de exigencia mental, siendo mayor en el área de seguimiento y control.

Riscos profissionais e lesões musculosqueléticas : na Indústria dos Moldes da Marinha Grande

As Lesões Musculosqueléticas Relacionadas com o Trabalho (LMERT) são patologias inflamatórias e degenerativas do sistema musculosquelético desenvolvidas pelos trabalhadores quando sujeitos a determinados riscos profissionais. O crescente número de trabalhadores tem vindo a aumentar com lesões musculosqueléticas, embora não tenhamos encontrado estudos que analisem as LMERT na indústria dos moldes. Este estudo teve como finalidade avaliar o grau de incidência das lesões musculosqueléticas bem como as localizações mais relatadas. A amostra constituiu-se por 196 trabalhadores masculinos inquiridos por questionário. Os dados permitiram caracterizar a amostra quanto a hábitos de vida, condições de trabalho, ambiente de trabalho, posturas adotadas nas tarefas laborais bem como retirar informações quanto a queixas relativas às LMERT, as causas, a localização, a frequência da dor. Os resultados revelam que os trabalhadores desempenham tarefas de caráter repetitivo, fundamentalmente de pé e com poucas pausas. Os sintomas musculosqueléticos mais frequentes situam-se na zona lombar, nos joelhos, nos braços e na cabeça, sendo nos trabalhadores com mais idade que se registam mais sintomas, assim como dores mais intensas e permanentes. O trabalho termina com algumas recomendações para trabalhos futuros.

Study of postures in sugarcane cutters in the Pontal of Paranapanema-SP, Brazil

The expansion of sugarcane monoculture in Brazil in the last decades has pointed out to the necessity of considering the question of sugarcane cutters occupational health. In this work we present a cross-sectional study aiming to examine the occupational posture of a group of sugarcane cutters, which work in a cane field located in the region of Pontal do Paranapanema-SP, Brazil. The study was made using the Ergonomic Analysis of Work - EAW methodology and the postural analysis method by Win-OWAS. Through the obtained records of postures, it was observed that during a workday the sugarcane cutters remain standing erect on two legs or in one leg 66% of the time and that their trunk remain tilted and in rotation, according to 63% of the positions categorized. It was also observed that the sugarcane cutter trunk performs repetitive and boundless movements during his routine of work, which can expose this individual to additional wear of their musculoskeletal functions. The activities in which the individual engages have favorable or adverse influence on his posture. The repetitive movements involved in specialized occupations are equivalent to repeated exercises, thus may be responsible for the excessive development of certain muscle groups. The study suggests that the postures adopted by sugarcane cutters can overload their musculoskeletal system and predispose the cutters to work-related musculoskeletal diseases.

Saúde do trabalhador: entre os dispositivos legais e as práticas efetivas

The health worker is seized in this research beyond the mere applicability of legal devices concerning the legislation of Labor, in order to be established correlations with activities alluding to the public power in the ambit of State of Rio Grande do Norte (RN). This dissertation is an cutting of analysis circumscribed in the research, "Accidents at work: law, citizenship and justice," of the Grupo de Estudos Seguridade Social e Trabalho (GESTO) of Universidade Federal do Rio Grande do Norte (UFRN). The overall goal turned to apprehend and relate contradictory elements inherent compliance of Occupational Health and Safety (OHS) in the supermarket which showed the highest occurrence of legal violations recognized by the Labor Justice of RN in the period between 2006 and 2008 . The specific objectives turned to identify, from the condemnatory sentences, violations inherent in the protective direction of the OH & S legislation; analyze the relationship of health damages to workers at the supposed recognition of rights claimed in condemnatory sentences and correlate violations inherent in the legislation OSH impacts on the health of workers, from data contained in expert reports. The justification for perform the research backed up, among other factors, in the fact that class of activity has been presented as the most recurrent in condemnatory sentences, since it chose to focus the analysis on documentary evidence from the supermarket which showed greater expression in relation to violations of the OSH legislation. From a qualitative perspective, the methodological approach was based on content analysis of thirteen condemnatory sentences, handed down by the potiguar labor justice, and three expert reports from a large supermarket in the city of Natal/RN. Aftermaths are evidenced relating to the cyclical processes of reorganization of capital, demanding requirements for labor organizations whose strategies for survival include identifying mechanisms to extract as much of the work force. Structural determination and ideological context that puts into question the historical achievements of workers, for example the legal devices aimed at preventing workplace accidents, expressed in this research as relativized, showing limitations of reach, as was inferred the indemnities, by material and moral damages, arising from Work-Related Musculoskeletal Diseases (MSDs'S), recognized by the laborite judiciary

Effects of resistance training in older women with knee osteoarthritis and total knee arthroplasty

OBJECTIVES: This study sought to analyze the effects of resistance training on functional performance, lower-limb loading distribution and balance in older women with total knee arthroplasty (TKA) and osteoarthritis (OA) in the contralateral knee. In addition, this older knee OA and TKA group (OKG) was compared to older (OG) and young women (YG) without musculoskeletal diseases who underwent the same resistance training program.METHODS: Twenty-three women divided into OKG (N = 7), OG (N = 8) and YG (N = 8) had their functional performance, lower-limb loading distribution and balance compared before and after 13 weeks of a twice-weekly progressive resistance training program.RESULTS: At baseline, the OKG showed lower functional performance and unilateral balance, and impaired lower-limb loading distribution compared to the OG and the YG (p<0.05). After resistance training, the OKG showed improvements in functional performance (similar to 13% in sit-to-stand and rising from the floor, similar to 16% in stair-climbing and similar to 23% in 6-minute walking (6 MW)), unilateral balance (similar to 72% and,78% in TKA and OA leg, respectively) and lower-limb loading distribution, which were greater than those observed in the OG and the YG. The OKG showed post-training 6 MW performance similar to that of the OG at baseline. Sit-to-stand performance and unilateral stand balance were further restored to post-training levels of the OG and to baseline levels of the YG.CONCLUSIONS: Resistance training partially restored functional, balance and lower-limb loading deficits in older women with TKA and OA in the contralateral knee. These results suggest that resistance training may be an important tool to counteract mobility impairments commonly found in this population.
