Posttransplant diabetes mellitus after kidney transplantation with different immunosuppressive agents.
No full textPosttransplant diabetes mellitus (PTDM) is a disturbing side effect of immunosuppression. The aim of this study was to evaluate the effect of different immunosuppressive agents on the development of PTDM in renal transplant recipients (KTx). The incidence of PTDM was evaluated in 538 consecutive KTx. Baseline immunosuppression was azathioprine (AZA), cyclosporine (CSA), or tacrolimus (TAC), or sirolimus in combination with calcineurin inhibitors (SIR). All patients received steroids for both induction and maintenance therapy during the first 6 months posttransplantation. Mean follow-up after KTx was 73 +/- 53.5 months (range 6 months to 16 years). PTDM was defined as two consecutive blood glucose determinations above 126 mg/dL. Thirty-six of 538 (6.7%) recipients experienced PTDM, 31 of whom required insulin treatment and five oral antidiabetic medications. PTDM occurred at 25.3 +/- 38 months posttransplantation in 4.8% of KTx treated with AZA, 4.8% of CSA, 6.5% of KTx treated with TAC and 12.5% of KTx treated with SIR. The time of onset of PTDM was significantly shorter (P =.003) among TAC (2.1 +/- 1.7 months posttransplantation) versus CSA (27.8 +/- 34 months). PTDM disappeared in 6 of 36 patients. We conclude that with current levels of immunosuppression, there is no difference in the incidence of PTDM between TAC- and CSA-treated KTx
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Twenty-four hour energy expenditure and skeletal muscle gene expression changes after bariatric surgery
No full textObesity is characterized by decreased insulin-stimulated glucose uptake in muscle and shift from glucose to lipid oxidation, the so-called metabolic inflexibility. Biliopancreatic diversion (BPD), a mainly malabsorptive bariatric operation, determines a prompt improvement of insulin resistance, but the mechanisms are still unclear
