Framingham score modification with weight loss due to bariatric surgery

Objetivo: Evaluar el comportamiento de diferentes factores de riesgo y del score de Framingham con la disminución de peso obtenida a través de cirugía bariátrica al ano˜ postoperatorio, en una clínica de obesidad durante los anos ˜ 2008 y 2011. Se evaluaron las modificaciones en los factores de riesgo y riesgo global con el score de Framingham al ano˜ postoperatorio, de una cohorte retrospectiva de 209 pacientes de la clínica de obesidad en un hospital universitario; los cambios se expresan como porcentajes de disminución respecto al valor prequirúrgico, en las variables nominales. Resultados: El peso y el índice de masa corporal tuvieron una reducción del 48% y 38%, respectivamente; el score de Framingham se redujo de 12,4 a 7,6 (35%), es decir, pasó de riesgo intermedio a bajo (menor al 10%). Así mismo, se observó disminución en los valores de hemoglobina glicosilada (14,7%), colesterol total (11,59%), colesterol-LDL (7%) y triglicéridos (31,4%), elevación del colesterol-HDL (15,3%), suspensión del uso de insulina (18%), disminución del 20% del valor de la glucosa y la HbA1c, a menos de 5,7 en un 23% de pacientes con glicemia alterada en ayunas, y finalmente, reducción de la presión arterial sistólica (9,2%) y diastólica. Conclusiones: La cirugía bariátrica es una herramienta válida en pacientes en quienes han fallado otros métodos clínicos para disminuir de peso e índice de masa corporal. Con ésta, además, se logra una disminución en el score de Framingham y se mejora el control de comorbilidades.Q4Articulo Original6-10Abstract Objective: To assess the behaviour of different risk factors and Framingham score with weight loss, obtained with bariatric surgery one year after surgery, in an obesity clinic during 2008 and 2011.Modifications of risk factors and global risk of the Framingham score one year after surgery, of a retrospective cohort of 209 patients of the obesity clinic at a University hospital. Changes are expressed as percentages of the decrease with regard to the pre-surgical values, in nominal values. Results: A 48% weight loss and 38% body mass index loss was observed, with a reduction of the Framingham score from 12.4 to 7.6 (35%), moving from an intermediate risk to a low risk (below 10%). A decrease of 14.7% in values of glycohemoglobin, 11.59% in total cholesterol, 7% of LDL cholesterol levels and 31.4% of triglycerides was observed, as well as a 15.3% raise in HDL cholesterol levels. 18% of patients with altered fasting glycaemia stopped taking insulin, glucose levels were reduced by 20% and A1c hemoglobin values were below 5.7 in 23% of the cases. Systolic pressure was reduced by 9.2%, same as the diastolic blood pressure. Conclusions: Surgery is a valid tool for patients were other clinical methods have failed, in order to lose weight and lower the body mass index, as well as reducing the Framingham score and improving the control of comorbidities

Growth characteristics of pullets based on type of housing

The objective of this work was to evaluate the growth of pullets housed in cages or floor stands. Two hundred birds were randomly sampled per house, from day one to 16 weeks of age. Birds housed on floor stands had the highest body weight and tarsus length, with high correlation between both variables, and the highest cumulative food consumption. The flock uniformity was 89% on floor and 79% in cages. Pullets housed on floor stands have a higher productive performance.El objetivo de este trabajo fue evaluar el crecimiento de pollitas alojadas en casetas de piso o jaulas. Fueron muestreadas de forma aleatoria 200 aves por caseta, desde el día uno hasta 16 semanas de edad. Las alojadas en piso registraron el mayor peso corporal y longitud de tarso, con alta correlación entre ambas variables, y el mayor consumo acumulado de alimento. La uniformidad de la parvada fue 89% en piso y 79% en jaula.

Aneurysmatic coronary artery disease : Presentation of a case and review the literature

La enfermedad aneurismática coronaria o ectasias y dilataciones de segmentos coronarios, son hallazgos típicamente incidentales en los estudios angiográficos. Aunque no está claramente establecida la etiología, muchas series describen como factor más común la aterosclerosis coronaria, pero también un desorden congénito, secundario a infl amación o enfermedad del tejido conectivo. Es bien estudiada su asociación con enfermedad de Kawasaki. Se revisa el caso de un paciente con síndrome coronario agudo (SCA) y dilataciones aneurismáticas en arterias coronarias, su enfoque diagnóstico y terapéutico.38-41Coronary artery aneurysms or ectasias are dilatations of arterial segments, which are typically incidentally identifi ed at angiography. Although the etiology isn ́t clearly established, several large clinical series described that the most common etiologic factor for coronary aneurysms is atherosclerotic coronary artery disease, but they can also be congenital or secondary to infl ammatory or connective tissue disorders. A well-known association with Kawasaki disease is also studied. We review the case of a patient with acute coronary syndrome (ACS) and aneurysms dilations in coronary arteries, its diagnosis and therapeutic approach

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.
