    BACKGROUND: The Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT), developed with innovative measurement methodologies, evaluates functioning of children and youth, from 0 to 21 years, with different health conditions. It is a revision of an earlier instrument (PEDI) that has been used in national and international clinical practice and research. It was felt to be necessary to make this new version (PEDI-CAT) available in Brazil. OBJECTIVES: Translate and culturally adapt the PEDI-CAT to the Brazilian-Portuguese language and test its psychometric properties. METHOD: This methodological study was developed through the following stages: (1) translation, (2) synthesis, (3) back-translation, (4) revision by an expert committee, (5) testing of the pre-final version, and (6) evaluation of the psychometric properties. The 276 translated PEDI-CAT items were divided into three age groups (0-7, 8-14, and 15-21 years). RESULTS: The PEDI-CAT translation followed all six stages. The adaptations incorporated cultural and socioeconomic class specificities. The PEDI-CAT/Brazil showed good indices of inter-examiner (intraclass correlation coefficient-ICC=0.83-0.89) and test-retest (ICC=0.96-0.97) reliability, good internal consistency (0.99) and small standard error of measurement in all three age groups (0.12-0.17). Factor analyses grouped the items from the three functional skills domains into one factor, and items from the responsibility scale into three factors, supporting the adequacy of these factor solutions to the conceptual structure of the instrument and the developmental model. CONCLUSION: The PEDI-CAT/Brazil is a theoretically consistent, culturally appropriate, and reliable instrument. Its availability in Brazil will contribute to the evaluation and measurement of functional outcomes from clinical interventions, longitudinal follow-up, and rehabilitation research

    ResumenLa reparación de la hernia ventral mediante abordajes mínimamente invasivos ha sido uno de los procedimientos de más tardía inclusión en la cartera de servicios de la cirugía endoscópica.La aparición de la cirugía endoscópica por orificios naturales (NOTES) ha abierto la posibilidad del empleo de estos nuevos abordajes para la reparación mínimamente invasiva de la pared abdominal.Hemos analizado los trabajos publicados y la experiencia personal para valorar en que situación estamos en la reparación parietal endoscópica y cómo estamos evolucionando hacia la mínima invasión empleando los orificios naturales en estos procedimientos.AbstractThe ventral hernia repair using minimally invasive approaches has been one of the last procedures included in the portfolio of minimally invasive endoscopic surgery.Natural orifice translumenal endoscopic surgery (NOTES) has offered the possibility of using these new approaches, especially transvaginal route, for minimally invasive repair of the abdominal wall.We have analyzed the literature and personal experience to assess where we are in the minimally invasive approach of the ventral hernia surgery and how we are moving towards minimally invasive natural orifice endoscopic surgery in these kind of procedures

    Vertex reconstruction for proton-proton collisions in ALICE

    Reconstructing the interaction vertex is a challenging task in the low multiplicity environment of pp collisions at the LHC. The two innermost layers of the Inner Tracking System (ITS), made of pixels, allow to obtain a first estimate of the vertex position, which can be provided also in a quasi-online mode, since only the local reconstruction is used. The optimal vertex measurement is obtained after the full event processing, using the tracks reconstructed in the ALICE barrel detectors. We present the methods for primary vertex reconstruction in pp collisions using pixels and tracks reconstructed in the ITS+TPC or in the TPC only. We also show the performance of the vertex finder in reconstructing displaced vertices originated by short-lived particles like charmed mesons

    Strategies to control Staphylococcus epidermidis biofilms

    Staphylococcus epidermidis is the staphylococci species most commonly associated with bacteremia and hospital-acquired infections and has recently arisen as the leading cause of infections related to indwelling medical devices such as vascular catheters, prosthetic joints and artificial heart valves. The prevalence of S. epidermidis in hospital-acquired infections is due to its ability to adhere and form biofilms on biomaterial surfaces. This feature is one of the most important virulence factors found in S. epidermidis. In biofilm form, bacteria are protected from antimicrobial agents and the host immune system contributing to the persistence of biofilm infections. In addition, the emergence of S. epidermidis resistance to conventional therapies, based in the use of traditional antibiotics, leads to the failure of the current treatments used in the combat of S. epidermidis infections and is becoming a major concern. These facts are stimulating the continuous search for novel agents able to eradicate S. epidermidis biofilm infections or that can work in synergy with the currently available antimicrobial agents. New strategies have been showing encouraging in vitro results in controlling S. epidermidis biofilms and seem to be promising alternatives to standard antibiotics usually used in the treatment of S. epidermidis related infections

    We prove upper pointwise estimates for the Bergman kernel of the weighted Fock space of entire functions in L2(e2ϕ)L^2(e^{-2\phi}) where ϕ\phi is a subharmonic function with Δϕ\Delta \phi a doubling measure. We derive estimates for the canonical solution operator to the inhomogeneous Cauchy-Riemann equation and we characterize the compactness of this operator in terms of Δϕ\Delta \phi
