Búsqueda, selección e implantación de un sistema online de software libre para revisión por pares en congresos científicos

Este proyecto tiene como objetivo implementar un sistema libre bajo GNU/Linux para la recepción y evaluación de trabajos presentados a un congreso argentino sobre sistemas embebidos. Además, se piensa en un futuro en organizar un evento de software libre con revisión de pares, para lo cual sería coherente utilizar un sistema con licencia de software libre.

Is amoxicillin/clavulanic acid sufficient for preemptive antibiotic therapy in type III grade open fractures ?

The risk of infection after type III° open fractures is high (10-50%).Preemptive antibiotic therapy may prevent posttraumatic infection andimprove the outcome. Recommendations about the type and durationof antibiotic vary among the institutions and it remains unclear whethergram-negative bacilli or anaerobs need to be covered. In Europe, themost commonly recommended antibiotic is amoxicillin/clavulanic acid.We retrospectively analyzed microbiology, characteristics and outcomeof patients with open type III° fractures treated at our institution.Methods: Between 01/2005 and 12/2009 we retrospectively includedall type III grade open fractures of the leg at our institution classifiedafter Gustilo into type IIIA, IIIB and IIIC. Demographic characteristics,clinical presentation, microbiology, surgical and antibiotic treatmentand patient outcome were recorded using a standardized case-reportform.Results: 30 cases of patients with type III° open fractures wereincluded (25 males, mean age was 40.5 years, range 17-67 years).27 fractures (90%) were located on the lower leg and 3 (10%) on theupper leg. Microbiology at initial surgery was available for 19 cases(63%), of which 10 grew at least one organism (including 8 amoxicillin/clavulanic acid-resistant gram-negative bacilli [GNB], 7 amoxicillin/clavulanic acid-resistant Bacillus cereus), 11 were culture-negative.Preemptive antibiotics were given in all cases (100%) for an averageduration of 8.5 days (range 1-53 days), the most common antibioticwas amoxicillin/clavulanic acid in 60% (n = 18). 11 cases just receivedpreemptive antibiotic treatment, in 19 of 30 cases the antibiotic therapywas changed and prolonged. Microbiology at revision surgery wasavailable for 25 cases and 22 grew at least one pathogen (including32 amoxicillin/clavulanic acid-resistant gram-negative bacilli and 10amoxicillin/clavulanic acid-resistant Bacillus cereus), 3 were culturenegative.Conclusions: At initial surgery, most common isolated organismswere coagulase-negative staphylococci (43%), Bacillus cereus (23%),and gram-negative bacilli (27%), and others (7%) of which 48% wereresistant to amoxicillin/clavulanic acid. At revision surgery, isolatedorganisms were gram-negative bacilli (64%), Bacillus cereus (20%),and others (16%) of which 88% were resistant to amoxicillin/clavulanicacid. The spectrum of amoxicillin/clavulanic does not cover the mostcommon isolated organisms.FM32

Predictors of return to work after a knee injury in patients hospitalized in vocational rehabilitation

Introduction.- Knee injuries are frequent in a young and active population. Most of the patients resume their professional activity but few studies were interested in factors that predict a return to work. The aim of this study is to identify these predictors from a large panel of bio-psychosocial variables. We postulated that the return to work 3 months and 2 years after discharge is mostly predicted by psychosocial variables.Patients and methods.- Prospective study, patients hospitalized for a knee injury. Variables measured: the abbreviated injury score (AIS) for the gravity of the injuries, analog visual scale for the intensity of pain, INTERMED for the bio-psychosocial complexity, SF-36 for the quality of life, HADs for the anxiety/depression symptoms and IKDC score for the knee function. Univariate logistic regressions, adjusted for age and gender, were performed in order to predict return to work.Results.- One hundred and twenty-six patients hospitalized during 8 months after the accident were included into this prospective study. A total of 73 (58%) and 75 (59%) questionnaires were available after 3 months and 2 years, respectively. The SF-36 pain was the sole predictor of return to work at 3 months (odds Ratio 1.06 [1.02-1.10], P = 0.01; for a one point increase) and 2 years (odds Ratio 1.06 [1.02-1.10], P = 0.01). At three months, other factors are SF-36 (physic sub-scale), IKDC score, the presence of a work contract and the presence of litigation. The bio-psychosocial complexity, the presence of depressive symptoms predicts the return to work at two years.Discussion.- Our working hypothesis was partially confirmed: some psychosocial factors (i.e. depressive symptoms, work contract, litigation, INTERMED) predict the return to work but the physical health and the knee function, perceived by the patient, are also correlated. Pain is the sole factor isolated at both times (i.e. 3 months and 2 years) and, consequently, appears a key element in the prediction of the return to work. Some factors are accessible to the rehabilitation program but only if an interdisciplinary approach is performed.
