6. Rehabilitación en la arteriopatía de los miembros inferiores

Author

Jean-Marie Casillas, V. Gremeaux, A. Hannequin, Charles Joussain, Yves Laurent, and D. Besson

Abstract

La rehabilitacion en la arteriopatia de los miembros inferiores se basa en programas personalizados que asocian readaptacion al esfuerzo y educacion terapeutica. Aumenta las capacidades fisicas, sobre todo la distancia de la marcha, permite reanudar las actividades, reduce los factores de riesgo y mejora los frecuentes trastornos del estado de animo que se observan en estos pacientes. Mejora las anomalias fisiopatologicas, en especial el desequilibrio neurovegetativo y la disfuncion endotelial. Se recomienda un programa ambulatorio de al menos tres sesiones por semana durante 2-3 meses. La evaluacion funcional (pruebas de esfuerzo maximo, pruebas de marcha) permite adaptar el programa de readaptacion mejorando las capacidades oxidativas. La educacion terapeutica apunta a un cambio permanente de las costumbres nutricionales (dieta mediterranea), a estimular la actividad fisica, la abstinencia de tabaco y la observancia farmacologica, sin olvidar el patron psicologico y las condiciones socioeconomicas de cada paciente. Esta rehabilitacion se indica sobre todo cuando la expresion clinica de la claudicacion arterial se agrava, los factores de riesgo no estan controlados y existe un peligro de desinsercion sociolaboral. Puede servir como prueba terapeutica de las lesiones popliteas antes de una revascularizacion o completar este tratamiento invasivo en caso de necesidad. Representa una accion terapeutica intensiva que se justifica ante una enfermedad grave por su mortalidad cardiaca, vascular y cerebrovascular, y por su prevalencia creciente.

Abstract

Alloying of gold atoms into nanometer-sized antimony clusters deposited on highly oriented pyrolitic graphite (HOPG) has been studied by transmission electron microscopy (TEM) for morphological and structural characterisations and by energy dispersive X-ray spectroscopy (EDX) for analysis of composition. First, large antimony clusters (≈5.4 nm) generated by the gas aggregation technique in a thermal source were deposited on HOPG. These antimony clusters diffused on graphite and formed, by collision and irreversible sticking, ramified islands the density of which can be predicted, prior to deposition, with suitable cluster flux and substrate temperature. Then, the gold atoms were evaporated at various mean thicknesses on the same Sb N –HOPG substrate. For this post-deposition of gold, the morphology of the deposit was quite different, depending on the evaporation method (Knudsen cell heated by electron bombardment or spiral tungsten filament heated by the Joule effect): ramified islands of Sb–Au alloys plus gold supported particles when using the first method and only ramified Sb–Au islands for the second one. In this paper, we give an explanation of these two different morphologies and we study the alloy formation versus the gold content.

Abstract

We have observed two new decay modes of the charmed baryon $\Xi_c^+$ into $\Sigma^+ K^-\pi^+$ and $\Sigma^+ \bar{K}^{*0}$ using data collected with the CLEO II detector. We also present the first measurement of the branching fraction for the previously observed decay mode $\Xi_c^+\to\Lambda K^-\pi^+\pi^+$. The branching fractions for these three modes relative to $\Xi_c^+\to\Xi^-\pi^+\pi^+$ are measured to be $1.18 \pm 0.26 \pm 0.17$, $0.92 \pm 0.27 \pm 0.14$, and $0.58 \pm 0.16 \pm 0.07$, respectively.

Abstract

Introduction Coordination between shoulder and pelvis girdles during walking is pivotal to optimise a stable forward displacement (Lamoth and van Heuvelen, 2012). Hip osteoarthritis (HOA) increases the stiffness of the pelvis and the low back and should impair this coordination. To our knowledge, no study evaluates this outcome for HOA. The aim was to evaluate the psychometric properties of the pelvis-shoulder coordination in healthy (HEA) and non-severe unilateral HOA subjects. Material and methods HEA and HOA subjects were enrolled. Each participant performed a 3D gait analysis along a 6-metre walkway using an optoelectronic system with 8 cameras (100 Hz). HOA performed a second session to evaluate measurement's reliability (test-retest). Pelvis and shoulder yaws (transverse plane) and rolls (frontal plane) were calculated using markers positioned on the acromial process and the anterior-superior iliac spines. The phase-lag between angle waveforms expressed as a gait cycle's percentage was computed using continuous estimate of relative phase (CRP; Russell Esposito and Wilken, 2014). Intraclass correlation (ICC), one-way Anova and Pearson correlation coefficient were used to evaluate respectively, reliability, responsiveness and validity (against HOOS scores; Ornetti et al., 2009). Results Seventy-eight HEA (58.4 ± 15.4 years) and 103 HOA (61.0 ± 8.1 years) subjects were included. ICC were excellent for roll-lag (0.918) and yaw-lag (0.959). Significant difference was found for roll-lag between subjects (HEA 37.8 ± 10.6%; OA 29.5 ± 9.8%, P r > 0.24, P r = −0.27, P = 0.013 for Lesquene index). Discussion–conclusion Pelvis-shoulder coordination outcomes showed excellent reliability. Roll-lag was related to clinical scores whereas yaw-lag did not. As only non-severe patients were included, these outcomes need to be addressed in population with higher impairment. It could be then proposed as an objective outcome to evaluate deficit in hip osteoarthritis patients.

Abstract

We have measured the weak decay asymmetry parameters ($\aLC $) for two \LC\ decay modes. Our measurements are $\aLC = -0.94^{+0.21+0.12}_{-0.06-0.06} $ for the decay mode $\Lambda_c^+ \to \Lambda\pi^+ $ and $\aLC = -0.45\pm 0.31 \pm 0.06$ for the decay mode $\Lambda_c \to \Sigma^+\pi^0 $. By combining these measurements with the previously measured decay rates, we have extracted the parity-violating and parity-conserving amplitudes. These amplitudes are used to test models of nonleptonic charmed baryon decay.

Abstract

Introduction Chez les patients atteints d’une BPCO moderee a severe, l’adaptation de la ventilation (V′E) lors de l’exercice physique concentrique (CONC) est limitee par une contrainte portant sur l’augmentation du volume courant (Vt). Du fait de son faible cout cardiorespiratoire, l’exercice excentrique (EXC) pourrait etre une alternative au CONC chez ces patients. L’objectif de ce travail etait de comparer l’adaptation ventilatoire a l’effort entre exercices de pedalage CONC et EXC. Methodes Treize patients atteints de BPCO moderee a severe (VEMS : 1,27 ± 0,31 L ; 44,5 ± 10,7 %Pred) ont effectue une epreuve d’effort incrementale CONC maximale et 4 seances de 30 minutes de pedalage EXC. Le V′E maximal observe en EXC a ete determine, et le V′E correspondant en CONC a ete obtenu par interpolation lineaire. Plusieurs parametres (Vt, frequence respiratoire [FR], consommation d’oxygene [V′O 2 ], quotient respiratoire [QR], frequence cardiaque [FC], score de dyspnee [Borg]) ont ete compares a iso-V′E en CONC et en EXC. Resultats Le V′E maximum en EXC et le V′E correspondant en CONC etaient respectivement de 26,1 ± 7,9 et 26,1 ± 8,0 L. min −1 , soit 60,6 ± 21,2 % de la VMM calculee (35 × VEMS). Le Vt est plus faible d’environ 12 % en EXC qu’en CONC (981 ± 221 vs. 1098 ± 315 mL, respectivement ; p −1 ). En revanche, la V′O 2 , la FC et le score de Borg etaient similaires dans les conditions EXC et CONC (respectivement, 0,81 ± 0,23 vs. 0,83 ± 0,27 L ; 97 ± 11 vs. 97 ± 14 min −1 et 2,5 ± 2,5 vs. 1,8 ± 1,0). Conclusion Pour la V’E maximale observee lors de l’exercice EXC chez des patients avec une BPCO moderee a severe, le Vt est plus faible et la FR plus elevee qu’en CONC, comme observe a iso-V′O 2 /V′E par Lechauve et al. [1] chez des sujets sains. Meme si cela ne se traduit pas par un niveau de dyspnee different, les consequences de cette hyperpnee lors d’un entrainement EXC dans la BPCO meritent d’etre etudiees.

Abstract

We have studied the leptonic decay of the $\Upsilon (1S)$ resonance into tau pairs using the CLEO II detector. A clean sample of tau pair events is identified via events containing two charged particles where exactly one of the particles is an identified electron. We find $B(\Upsilon(1S) \to \tau^+ \tau^-) = (2.61~\pm~0.12~{+0.09\atop{-0.13}})%$. The result is consistent with expectations from lepton universality.

Abstract

We have observed the previously unseen decay modes Λπ+π0, Σ0π+π0 and Σ0π−π+π+ of the charmed baryon Λc+, as well as Λc+→Σ0π+ observed previously by ARGUS. The branching ratios for these four decay modes relative to Λc+→pK−π+ are measured to be 0.73 ±0.09± 0.16, 0.36 ±0.09±0.10, 0.21±0.05±0.05, and 0.21±0.02 ±0.04, respectively. Using the recent CLEO measurement of the branching ratio for Λc+→pK− π+, these modes account for 6% of Λc+ decays.

Abstract

Using a sample of integrated luminosity 1.68 fb−1 collected with the CLEO-II detector at the Cornell Electron Storage Ring, we measure the branching ratios for the dominant exclusive semileptonic decays D → K l ν and D → K ∗ l ν , using charged and neutral D mesons. We also make a precise measurement of the vector form factor for the decay D 0 → K − l + ν , using a sample of 2700 events.

Abstract

Using the CsI calorimeter of the CLEO-II detector, we have studied exclusive radiative decays of the ϒ(3S) to the χ (2P) states where the final state consists of two photons and two leptons (e + e − or μ + μ − , from either the ϒ(1S) or ϒ(2S)). We observe and measure branching ratios for the J =2 and J =1 χ b (2 3 P J ) states, and set upper limits for the J =0 state.

Abstract

The new detector for data recording by the CLEO collaboration at the Cornell Electron Storage Ring is described. This detector has been designed to optimize studying e+ e− annihilation into hadronic matter at a total energy of 10 GeV. It consists of high precesion charged particle tracking chambers and an electromagnetic calorimeter together with systems for particle identification. The design of the detector and its performance over the first year and a half of operation are presented.

Abstract

We report on a study of charged and neutral K ∗ production in tau decay. We obtain a branching ratio value BR (τ − → K ∗- ν τ X 0 ) = (1.43±0.11±0.13)% where X 0 designates possible unobserved neutral particles (charge conjugate modes are implicit). We observe the first signals for inclusive K ∗0 and K ∗0 production in τ − decay, and determine the inclusive branching ratios τ − →K ∗0 K − ν τ X 0 and τ − K ∗0 π − ν τ X 0 to be (0.32±0.08±0.12)% and (0.38±0.11±0.13)%, respectively. We have searched for the decay τ − → K 0 K − ν τ X 0 and set a limit of 8 × 10 −3 at 90% confidence level.

Abstract

Using the CLEO detector at the Cornell Electron Storage Ring, we have searched for two-photon production of charmonium in four-track final states. We have measured Γ γγ ( η c )=5.9 +2.1 −1.8 ±1.9 keV, and we have obtained 95% CL upper limits of Γ γγ ( X c 0 ) Γ γγ ( X c 2 )

Abstract

BACKGROUND: Heart rate (HR) at the ventilatory threshold (VT) is often used to prescribe exercise intensity in cardiac rehabilitation. Some studies have reported no significant difference between HR at VT and HR measured at the end of a 6-min walk test (6-MWT) in cardiac patients. The aim of this work was to assess the potential equivalence between those parameters at the individual level. METHOD: Three groups of subjects performed a stress test and a 6-MWT: 22 healthy elderlies (GES, 77 +/- 3.7 years), 10 stable coronary artery disease (CAD) patients (GMI, 50.9 +/- 4.2 years) and 30 patients with chronic heart failure (GHF, 63.3 +/- 10 years). We analyzed the correlation, mean bias, 95% confidence interval (95% CI) of the mean bias and the magnitude of the bias between 6-MWT-HR and VT-HR. RESULTS: There was a significant difference between 6-MWT and VT-HR in GHF (99.1 +/- 8.8 vs 91.6 +/- 18.6 bpm, P=0.016) but not in GES and GMI. The correlation between those 2 parameters was high for GMI (r=0.78, P\textless0.05), and moderate for GES and GHF (r=0.48 and 0.55, respectively, P\textless0.05). The 95% CI of bias was large (\textgreater30%) in GES and GHF and acceptable in GMI (8-12%). CONCLUSION: 6-MWT-HR and VT-HR do not appear interchangeable at the individual level in healthy elderlies and CHF patients. In CAD patients, further larger studies and/or the development of other walk tests could help in confirming the interest of a training prescription based on walking performance, after an exhaustive study of their cardiometabolic requirements.

Abstract

Using the CLEO detector, we have measured the branching ratios for the exclusive decays of the D s + meson into K ∗0 K + , K 0 K + , and K ∗+ K 0 relative to the decay D s + →φπ + to be close to unity. We have also measured the mass diference between the D s + and D + meson to be 98.5±1.5 MeV/ c 2 .

Abstract

We have searched in the decays of the ϒ(1S), ϒ(2S) and B mesons for the narrow state, γ, seen by the Mark II group in radiative ψ decay. We find the product branching fractions B[ϒ(1S) → γγ]·B[γ → K+K−], B[ϒ(2S) → γ γ]· B[γ → K+K−] and B[B → γX]·B[γ → K+K−] to be less than 2×10−4, 9×10−5 and 3×10−3, respectively at 90% confidence level. These limits constrain theoretical models if the γ is interpreted as a Higgs boson.

Abstract

We have measured the lifetimes of the D0, D+ and Ds+ mesons with data from the CLEO detector. We find τD0 = (5.0 ± 0.7 ± 0.4) × 10−13s, τD+ = (11.4 ± 1.6 ± 0.7) × 10−13s and τDs+ = (4.7 ± 2.2 ± 0.5) × 10−13s, giving lifetime ratios τD+/τD0 = 2.3 ± 0.5 and τDs+/τD0 = 0.9 ± 0.5.
