Abstract

BackgroundIn Mexico, although the majority of births are attended in hospitals, reports have emerged of obstetric violence, use of unsafe practices, and failure to employ evidence-based practices (EBP). Recent attention has refocused global efforts towards provision of quality care that is both patient-centered and evidence-based. Scaling up of local interventions should rely on strong evidence of effectiveness.ObjectiveTo perform a secondary analysis to evaluate the impact of a simulation and team-training program (PRONTO) on the performance of EBP in normal births.MethodsA pair-matched cluster randomized controlled trial of the intervention was designed to measure the impact of the program (PRONTO intervention) on a sample of 24 hospitals (12 hospitals received the PRONTO training and 12 served as controls) in the states of Chiapas, Guerrero, and Mexico. We estimated the impact of receiving the intervention on the probability of birth practices performance in a sample of 641 observed births of which 318 occurred in the treated hospitals and 323 occurred in control hospitals. Data was collected at 4 time points (baseline, 4th, 8th and 12th months after the training). Women were blinded to treatment allocation but observers and providers were not. Estimates were obtained by fitting difference-in-differences logistic regression models considering confounding variables. The trial is registered at clinicaltrials.gov: # NCT01477554.ResultsSignificant changes were found following the intervention. At 4 months post-intervention an increase of 20 percentage points (p.p.) for complete Active Management of Third Stage of Labor (AMTSL) (p = 0.044), and 16 p.p. increase for Skin-to-Skin Contact (p = 0.067); at 12 months a 25 p.p. increase of the 1st step of AMTSL (p = 0.026) and a 42 p.p. increase of Delayed Cord Clamping (p = 0.004); at 4 months a 30 (p = 0.001) and at 8 months a 22 (p = 0.010) p.p. decrease for Uterine Sweeping.ConclusionsThe intervention has an impact on adopting EBP at birth, contributing to an increased quality of care. Long lasting impacts on these practices are possible if there were to be a widespread adoption of the training techniques including simulation, team-training and facilitated discussions regarding routine care.

9. Noncommutative Classical Dynamics on Velocity Phase Space and Souriau Formalism

Subjects
Mathematical Physics, 70Hxx, 53Dxx
Abstract

We consider Feynman-Dyson's proof of Maxwell's equations using the Jacobi identities on the velocity phase space. In this paper we generalize the Feynman-Dyson's scheme by incorporating the non-commutativity between various spatial coordinates along with the velocity coordinates. This allows us to study a generalized class of Hamiltonian systems. We explore various dynamical flows associated to the Souriau form associated to this generalized Feynman-Dyson's scheme. Moreover, using the Souriau form we show that these new classes of generalized systems are volume preserving mechanical systems., Comment: 30 pages, few references have been added

Abstract

Scimitar Syndrome is a rare congenital disorder and a variant of partial anomalous pulmonary venous connection (PAPVC) in which part or even the entire right lung is drained by right pulmonary veins that connect anomalously to the Inferior Vena Cava (IVC). It has various presentations including exertional dyspnea, recurrent chest infection, pulmonary artery hypertension, and hemoptysis. The initial diagnosis of PAPVC may be made by echocardiography and is typically confirmed by magnetic resonance imaging, computed tomography, or cardiac catheterization.We report a 69-year-old man with progressive dyspnea on exertion associated with palpitations of five years of evolution. The patient was diagnosed with cardiomyopathy, pulmonary hypertension and was started on treatment with anticoagulation, digoxin, and metoprolol for his atrial fibrillation. Despite the treatment, the dyspnea did not improve. The patient underwent cardiac catheterization, where the anomalous venous drainage was confirmed. Scimitar syndrome was corrected by surgical intervention with complete resolution of symptoms.

Subjects
Mathematics - Combinatorics, High Energy Physics - Theory, 16T30(Primary), 05A17 (Secondary)
Abstract

This is a short review on the Fa\`a di Bruno formulas, and some Hopf algebras associated to them. These allow, among several other things, a short proof of the Lie-Scheffers theorem, and relating the Lagrange inversion formulas with antipodes. The link of Fa\`a di Bruno formulas with the theory of set partitions is developed in some detail., Comment: Latex, 9 pages.

15. Combinatorial Hopf algebras in quantum field theory I

Author

Figueroa, Hector and Gracia-Bondia, Jose M.

Subjects
High Energy Physics - Theory, Mathematics - Combinatorics
Abstract

This manuscript stands at the interface between combinatorial Hopf algebra theory and renormalization theory. Its plan is as follows: Section 1 is the introduction, and contains as well an elementary invitation to the subject. The rest of part I, comprising Sections 2-6, is devoted to the basics of Hopf algebra theory and examples, in ascending level of complexity. Part II turns around the all-important Faa di Bruno Hopf algebra. Section 7 contains a first, direct approach to it. Section 8 gives applications of the Faa di Bruno algebra to quantum field theory and Lagrange reversion. Section 9 rederives the related Connes-Moscovici algebras. In Part III we turn to the Connes-Kreimer Hopf algebras of Feynman graphs and, more generally, to incidence bialgebras. In Section10 we describe the first. Then in Section11 we give a simple derivation of (the properly combinatorial part of) Zimmermann's cancellation-free method, in its original diagrammatic form. In Section 12 general incidence algebras are introduced, and the Faa di Bruno bialgebras are described as incidence bialgebras. In Section 13, deeper lore on Rota's incidence algebras allows us to reinterpret Connes-Kreimer algebras in terms of distributive lattices. Next, the general algebraic-combinatorial proof of the cancellation-free formula for antipodes is ascertained; this is the heart of the paper. The structure results for commutative Hopf algebras are found in Sections 14 and 15. An outlook section very briefly reviews the coalgebraic aspects of quantization and the Rota-Baxter map in renormalization., Comment: 94 pages, LaTeX figures, precisions made, typos corrected, more references added

16. The uses of Connes and Kreimer's algebraic formulation of renormalization theory

Author

Figueroa, Hector and Gracia-Bondia, Jose M.

Subjects
High Energy Physics - Theory
Abstract

We show how, modulo the distinction between the antipode and the "twisted" or "renormalized" antipode, Connes and Kreimer's algebraic paradigm trivializes the proofs of equivalence of the (corrected) Dyson-Salam, Bogoliubov-Parasiuk-Hepp and Zimmermann procedures for renormalizing Feynman amplitudes. We discuss the outlook for a parallel simplification of computations in quantum field theory, stemming from the same algebraic approach., Comment: 15 pages, Latex.

Abstract

We give a new formula for the antipode of the algebra of rooted trees, directly in terms of the bialgebra structure. The equivalence, proved in this paper, among the three available formulae for the antipode, reflects the equivalence among the Bogoliubov-Parasiuk-Hepp, Zimmermann, and Dyson-Salam renormalization schemes., Comment: Plain TeX, 7 pages, uses XyPic fonts; minor changes, 2 references added

21. Hamiltonian versus Lagrangian formulations of supermechanic

Author

Cariñena, José F. and Figueroa, Hector

Subjects
Mathematics - Differential Geometry, Mathematical Physics
Abstract

We take advantage of different generalizations of the tangent manifold to the context of graded manifolds, together with the notion of super section along a morphism of graded manifolds, to obtain intrinsic definitions of the main objects in supermechanics such as, the vertical endomorphism, the canonical and the Cartan's graded forms, the total time derivative operator and the super--Legendre transformation. In this way, we obtain a correspondence between the Lagrangian and the Hamiltonian formulations of supermechanics., Comment: Plain TeX, 24 pages. Submitted to J. Phys. A
