Statins and Exercise Training Response in Heart Failure Patients: Insights From HF-ACTION.
OBJECTIVES: The aim of this study was to assess for a treatment interaction between statin use and exercise training (ET) response.
BACKGROUND: Recent data suggest that statins may attenuate ET response, but limited data exist in patients with heart failure (HF).
METHODS: HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) was a randomized trial of 2,331 patients with chronic HF with ejection fraction ≤35% who were randomized to usual care with or without ET. We evaluated whether there was a treatment interaction between statins and ET response for the change in quality of life and aerobic capacity (peak oxygen consumption and 6-min walk distance) from baseline to 3 months. We also assessed for a treatment interaction among atorvastatin, simvastatin, and pravastatin and change in these endpoints with ET. Multiple linear regression analyses were performed for each endpoint, adjusting for baseline covariates.
RESULTS: Of 2,331 patients in the HF-ACTION trial, 1,353 (58%) were prescribed statins at baseline. Patients treated with statins were more likely to be older men with ischemic HF etiology but had similar use of renin angiotensin system blockers and beta-blockers. There was no evidence of a treatment interaction between statin use and ET on changes in quality of life or exercise capacity, nor was there evidence of differential association between statin type and ET response for these endpoints (all p values \u3e0.05).
CONCLUSIONS: In a large chronic HF cohort, there was no evidence of a treatment interaction between statin use and short-term change in aerobic capacity and quality of life with ET. These findings contrast with recent reports of an attenuation in ET response with statins in a different population, highlighting the need for future prospective studies.

Understanding the effect of sheared flow on microinstabilities
The competition between the drive and stabilization of plasma
microinstabilities by sheared flow is investigated, focusing on the ion
temperature gradient mode. Using a twisting mode representation in sheared slab
geometry, the characteristic equations have been formulated for a dissipative
fluid model, developed rigorously from the gyrokinetic equation. They clearly
show that perpendicular flow shear convects perturbations along the field at a
speed we denote by (where is the sound speed), whilst parallel
flow shear enters as an instability driving term analogous to the usual
temperature and density gradient effects. For sufficiently strong perpendicular
flow shear, , the propagation of the system characteristics is
unidirectional and no unstable eigenmodes may form. Perturbations are swept
along the field, to be ultimately dissipated as they are sheared ever more
strongly. Numerical studies of the equations also reveal the existence of
stable regions when , where the driving terms conflict. However, in both
cases transitory perturbations exist, which could attain substantial amplitudes
before decaying. Indeed, for , they are shown to exponentiate
times. This may provide a subcritical route to turbulence in
tokamaks.Comment: minor revisions; accepted to PPC
Caval-Aortic Access to Allow Transcatheter Aortic Valve Replacement in Otherwise Ineligible Patients Initial Human Experience
ObjectivesThis study describes the first use of caval-aortic access and closure to enable transcatheter aortic valve replacement (TAVR) in patients who lacked other access options. Caval-aortic access refers to percutaneous entry into the abdominal aorta from the femoral vein through the adjoining inferior vena cava.BackgroundTAVR is attractive in high-risk or inoperable patients with severe aortic stenosis. Available transcatheter valves require large introducer sheaths, which are a risk for major vascular complications or preclude TAVR altogether. Caval-aortic access has been successful in animals.MethodsWe performed a single-center retrospective review of procedural and 30-day outcomes of prohibitive-risk patients who underwent TAVR via caval-aortic access.ResultsBetween July 2013 and January 2014, 19 patients underwent TAVR via caval-aortic access; 79% were women. Caval-aortic access and tract closure were successful in all 19 patients; TAVR was successful in 17 patients. Six patients experienced modified VARC-2 major vascular complications, 2 (11%) of whom required intervention. Most (79%) required blood transfusion. There were no deaths attributable to caval-aortic access. Throughout the 111 (range 39 to 229) days of follow up, there were no post-discharge complications related to tract creation or closure. All patients had persistent aorto-caval flow immediately post-procedure. Of the 16 patients who underwent repeat imaging after the first week, 15 (94%) had complete closure of the residual aorto-caval tract.ConclusionsPercutaneous transcaval venous access to the aorta allows TAVR in otherwise ineligible patients, and may offer a new access strategy for other applications requiring large transcatheter implants
Reference to the index of the personal and miscellaneous correspondence and papers relating to agriculture, forestry, hydro electricity, welfare, education, economics and politics of William Ebenezer Shoobridge (1846-1940)
W. E. Shoobridge was educated at Horton College, where he was introduced to the study of hydraulics, chemistry and electricity, which he continued to study after leaving school in 1860,thinking of becoming an engineer. However in 1864 his father had the chance of acquiring Bushy Park estate with its water resources and W. E. Shoobridge, with his brothers, helped to develop it,later purchasing also Kentdale and Glenora and forming the firm of E. Shoobridge and Sons(later Shoobridge Brothers). W.E.Shoobridge constructed an irrigation system for the hopfields on Valleyfield and later replanned and reconstructed the irrigation works on Bushy Park(originally made by the first settler of Bushy Park Mr Humphries). In 1908,with the help of his son, Marcus,who had trained in the Westinghouse Factory in Canada, W.E. Shoobridge installed a hydro-electric plant for the estate. W.E.Shoobridge was especially interested in the development of water conservation, irrigation and hydro-electric schemes for Tasmania. In 1914 he went on a trade mission to Canada and the United States to inquire particularly into hydro-electric power schemes and industries connected with them, including papermaking,and irrigation schemes forcloser settlement. He negotiated the transfer of the Hydro-Electric scheme from the Electrolytic Zinc Company to the State Government and also consulted Dr.Fortier of Berkley,California,about plans for the use of Tasmanian water although these were rejected by the Legislative Council.W. E. Shoobridge also did much to develop the fruit industry, not only in irrigation and methods of pruning to allow the sun to shine equally on all fruit,but especially in developing a ventilated coolstore system to prevent deterioration of apples through "brown heart"
Evidence for a correlation between the sizes of quiescent galaxies and local environment to z ~ 2
We present evidence for a strong relationship between galaxy size and
environment for the quiescent population in the redshift range 1 < z < 2.
Environments were measured using projected galaxy overdensities on a scale of
400 kpc, as determined from ~ 96,000 K-band selected galaxies from the UKIDSS
Ultra Deep Survey (UDS). Sizes were determined from ground-based K-band
imaging, calibrated using space-based CANDELS HST observations in the centre of
the UDS field, with photometric redshifts and stellar masses derived from
11-band photometric fitting. From the resulting size-mass relation, we confirm
that quiescent galaxies at a given stellar mass were typically ~ 50 % smaller
at z ~ 1.4 compared to the present day. At a given epoch, however, we find that
passive galaxies in denser environments are on average significantly larger at
a given stellar mass. The most massive quiescent galaxies (M_stellar > 2 x
10^11 M_sun) at z > 1 are typically 50 % larger in the highest density
environments compared to those in the lowest density environments. Using Monte
Carlo simulations, we reject the null hypothesis that the size-mass relation is
independent of environment at a significance > 4.8 sigma for the redshift range
1 < z < 2. In contrast, the evidence for a relationship between size and
environment is much weaker for star-forming galaxies.Comment: Accepted for publication in MNRAS. 16 pages, 11 figures, 6 table
