O efeito em curto prazo do bypass gástrico sobre pacientes obesos diabéticos Short-term effect of gastric bypass in obese diabetic patients
Aluisio Stoll,Jean Carl Silva,Luiz Carlos Von Bahten,Giovana Gugelmin
Revista do Colégio Brasileiro de Cirurgi?es , 2013,
Abstract: OBJETIVO: estudar o efeito do bypass gástrico sobre a glicemia e o uso de medica o antidiabética em pacientes obesos portadores de diabetes. MéTODOS: estudo de coorte retrospectivo com 44 pacientes obesos portadores de DM2, provenientes de 469 pacientes submetidos ao bypass gástrico no período de dezembro de 2001 a mar o de 2009. Os desfechos primários avaliados foram: glicemia em jejum e a necessidade de medica o antidiabética. RESULTADOS: a popula o foi composta de dez (22,7%) homens e 34 (77,3%) mulheres, com média de idade de 45,3 (±8,23) anos e índice de massa corporal de 40,9 (±5,03) kg/m2. O tempo médio de evolu o do DM2 foi 63,6 (±60,9) meses. Dos 40 pacientes que utilizavam medica o para controle do DM2, 20 (50%) tiveram sua medica o suspensa na alta hospitalar e 13 (32,5%) até nove meses depois. Em uma paciente n o foi possível avaliar o uso de medica o, sendo essa a única exclus o. A insulina foi suspensa nos dez (100%) pacientes que a utilizavam, sendo seis (60%) na alta hospitalar. Houve redu o (P<0,05) da glicemia em jejum, em todo o período estudado, em compara o com o valor pré-operatório, e foram atingidos valores inferiores a 100mg/dl no período de sete a nove meses. CONCLUS O: Pacientes obesos portadores de DM2, submetidos ao bypass gástrico, apresentaram melhora do controle glicêmico e redu o do uso de hipoglicemiantes em curto prazo. OBJECTIVE: To study the effect of gastric bypass on blood glucose levels and the use of antidiabetic medication in obese patients with diabetes. METHODS: We carried out a retrospective cohort study with 44 obese patients with DM2, from 469 patients undergoing gastric bypass from December 2001 to March 2009. The primary endpoints evaluated were fasting glucose and the need for antidiabetic medication. RESULTS: The study population consisted of ten (22.7%) men and 34 (77.3%) women, with a mean age of 45.3 (±8.23) years and a body mass index of 40.9 (±5.03) kg/m2. The average time to progression of DM2 was 63.6 (±60.9) months. Of the 40 patients who used medication to control type 2 diabetes, 20 (50%) had their medication discontinued at discharge and 13 (32.5%), until nine months later. In one patient it was not possible to evaluate the use of medication, this being the only exception. Insulin was suspended in ten (100%) patients who used it, six (60%) at discharge. Fasting plasma glucose levels decreased throughout the study period (p <0.05) when compared with preoperative values, and values below 100mg/dl were achieved within seven to nine months. CONCLUSION: Obese patients with DM2 undergoing
Sobre moral, direito e democracia
Schumacher, Aluisio A.;
Lua Nova: Revista de Cultura e Política , 2004, DOI: 10.1590/S0102-64452004000100005
Abstract: from the idea that morality and law imply a reference to the participant's viewpoint, the author explains that, under modern conditions, the latter compensates the frailty of the former. based on habermas' discourse theory, the author argues for an internal relationship between democracy and the rule of law. firstly, because human rights and people's sovereignty are mutually implicated. secondly, because the idea of the rule of law now involves the concept of communicative power: an overlapping and interconnection of communication forms based on arguments. from this second relationship, the author arrives at an understanding of democracy in which the source of legitimacy is no longer found in an individual's predetermined will but in the the very act of deliberating.
Wavelet Functional Data Analysis for FANOVA Models under Dependent Errors
Airton Kist,Aluisio Pinheiro
Statistics , 2015,
Abstract: We extend the wavelet tests for fixed effects FANOVA models with iid errors, proposed in Abramovich et al, 2004 to FANOVA models with dependent errors and provide an iterative Cochrane-Orcutt type procedure to estimate the parameters and the functional. The function is estimated through a nonlinear wavelet estimator. Nonparametric tests based on the optimal performance of nonlinear wavelet estimators are also proposed. The method is illustrated on real data sets and in simulated studies. The simulation also addresses the test performance under realistic sample sizes.
Value distribution and the Lemma of the logarithmic derivative on polydiscs
Wilhelm Stoll
International Journal of Mathematics and Mathematical Sciences , 1983, DOI: 10.1155/s0161171283000587
Abstract: Value distribution is developed on polydiscs with the special emphasis that the value distribution function depend on a vector variable. A Lemma of the logarithmic derivative for meromorphic functions on polydiscs is derived. Here the Bergman boundary of the polydiscs is approached along cones of any dimension and exceptional sets for such an approach are defined.
An angle representation of QCD
Dieter Stoll
Physics , 1994,
Abstract: For the sake of eliminating gauge variant degrees of freedom we discuss the way to introduce angular variables in the hamiltonian formulation of QCD. On the basis of an analysis of Gauss' law constraints a particular choice is made for the variable transformation from gauge fields to angular field variables. The resulting formulation is analogous to the one of Bars in terms of corner variables and it is closely related to the hamiltonian lattice QCD formulation. Therefore the corner or angle formulation may constitute an useful starting point for the investigation of the low energy properties of QCD in terms of gauge invariant degrees of freedom.

Gauge fixing by unitary transformations in QCD
Dieter Stoll
Physics , 1994, DOI: 10.1016/0370-2693(94)90566-5
Abstract: The unitary gauge fixing technique is applied to the QCD hamiltonian formulated in terms of angular variables. It is demonstrated that in this formulation projections on the physical Hilbert space are unnecessary to separate physical and unphysical degrees of freedom. Therefore the application of the unitary gauge fixing technique can be extended to the operator level.
Mass corrections of vector meson distribution amplitudes

Physics , 1999,
Abstract: A model-independent way of computing the mass corrections of vector-meson distribution amplitudes is given. The method is based on resummation of (next-to-)leading twist local operator.
Light-cone wave functions of mesons
G. Stoll
Physics , 1998,
Abstract: A review of light-cone, covariant and gauge-invariant wave-functions of mesons is presented. They are basic non-perturbative objects needed for hard exclusive processes and for the method of light-cone QCD sum rules. The emphasis is on the vector mesons and a new (model-independent) way of computing the mass corrections of vector-meson wave functions is given.
