RESUMO
INTRODUCTION: Chronic kidney disease (CKD) is a priority problem due to its high prevalence. According to the modalities of renal replacement therapy, kidney transplantation (TR) offers to be the best alternative. TR presents multiple factors of dependence of success; among them is the management of the anatomical variants of the graft and the surgical decision on the basis of these. Therefore, the objective of this study is to determine the frequency of variants in the graft, its surgical management, and the impact on the functionality of the transplanted kidney. MATERIAL AND METHODS: This was an observational, retrospective study of patients in the renal transplant unit of the Siglo XXI National Medical Center from 2002-2016. The analysis begins in the description of the population doing bivariate analysis to establish relative risks. For variables with a central tendency, the parametric tests analysis of variance, Student t paired, and unpaired will be used. In the case of nominal variables, the proportion's difference will be estimated using the chi-square test, establishing significance when P is ≤ .05. SPSS 21 software was used. RESULTS: There were a total of 773 patients, with 576 transplants from living donors and 197 from deceased donors. In the case of the artery, a greater number of variants is observed-27.8% being alive versus 17.3% of the variants found in deceased donors. For the renal vein, 12.7% of the kidneys were taken from living donor vs 6.1% from deceased donors. This required one more day of hospitalization (6 vs 7 days of single vs multiple vessels); likewise, increases in immediate post-transplant infections were 5% for single vessels vs 8% in the case of multiple variants. CONCLUSIONS: The importance of knowing the anatomical variants prior to the TR allows them to plan the potential surgical maneuvers, decreasing the times aimed at improving the immediate functionality of the renal graft, while also considering the increase in hospital expenses due to the greater number of days of hospitalization.

Data with excess zeros are frequently found in practice, and the recommended analysis is to use models that adequately address the counting of zero observations. In this study, the Zero Inflated Beta Regression Model (BeZI) was used on experimental data to describe the mean incidence of leaf citrus canker in orange groves under the influence of genotype and rootstocks of origin. Based on the model, it was possible to quantify the odds that a null observation to mean incidence comes from a particular plant according to genotype and rootstock, and estimate its expected value according to this combination. Laranja Caipira rootstock proved to be the most resistant to leaf citrus canker as well as Limão Cravo proved to be the most fragile. The Ipiguá IAC, Arapongas, EEL and Olímpia genotypes have statistically equivalent chances.(AU)
Dados com excesso de zeros são encontrados muitas vezes na prática, e a análise recomendada é utilizar modelos que suportem adequadamente a contagem de observações nulas. Neste artigo, o Modelo de Regressão Beta Inflacionado de Zeros (BeZI) foi aplicado a dados experimentais para descrever a incidência média de cancro cítrico foliar em pomares de laranja sob a influência do genótipo e do portaenxerto de origem. Com base no modelo, foi possível quantificar as chances de que uma observação nula para a incidência média seja proveniente de uma determinada planta, de acordo com o genótipo e o portaenxerto, além de estimar o seu valor esperado conforme essa combinação. O porta-enxerto Laranja Caipira mostrou ser o mais resistente ao cancro cítrico foliar, assim como o Limão Cravo mostrou ser o mais suscetível. Os genótipos Ipiguá IAC, Arapongas, EEL e Olímpia apresentaram chances estatisticamente equivalentes.(AU)

Es conocido que la radiación ha sido asociada a una cicatrización disminuida de las heridas, necrosis grasa y decoloración. La quimioterapia, por otra parte, se ha descrito con efectos adversos como infección, necrosis, contractura o deformación de los colgajos. Los antecedentes previos son los causantes de cierta confusión al enfrentar pacientes oncológicos que durante su evolución requieren solucionar defectos de piel y tejidos blandos: es seguro realizar injertos o colgajos en un paciente que está siendo tratado con quimio o radioterapia? Por medio de la revisión de la literatura publicada buscamos dar respuesta a esta interrogante.
It is known that the radiation has been associated with decreased wound healing, fat necrosis and bleaching. Chemotherapy, on the other hand, has been described with side effects as infection, necrosis, contraction or deformation of the flaps. The previous history are causing some confusion that may arise when facing cancer patients that during their evolution require fix skin and soft tissue defects: is it safe do grafts or flaps in a patient being treated with chemotherapy or radiation therapy? Through the review of the published literature we seek to answer this question.
