Percutaneous Closure of Paravalvular Leaks: A Systematic Review
[EN] Paravalvular leak (PVL) is an uncommon yet serious complication associated with the implantation of mechanical or
bioprosthetic surgical valves and more recently recognized with transcatheter aortic valves implantation (TAVI). A significant
number of patients will present with symptoms of congestive heart failure or haemolytic anaemia due to PVL and need further
surgical or percutaneous treatment. Until recently, surgery has been the only available therapy for the treatment of clinically
significant PVLs despite the significant morbidity and mortality associated with re-operation. Percutaneous treatment of PVLs
has emerged as a safe and less invasive alternative, with low complication rates and high technical and clinical success rates.
However, it is a complex procedure, which needs to be performed by an experienced team of interventional cardiologists and
echocardiographers. This review discusses the current understanding of PVLs, including the utility of imaging techniques in PVL
diagnosis and treatment, and the principles, outcomes and complications of transcatheter therapy of PVLs. (J Interven Cardiol

Interdisciplinary approach to better characterize sediments in dry detention basins - the French Cabrres programme
Knee instruments and rating scales designed to measure outcomes
In this article, the knee instruments and rating scales that are designed to measure outcomes are revised. Although the International Knee Documentation Committee Subjective Knee Form can be used as a general knee measure, no instrument is currently universally applicable across the spectrum of knee disorders and patient groups. Clinicians and researchers looking to use a patient-based score for measurement of outcomes must consider the specific patient population in which it has been evaluated. The Western Ontario and McMaster Universities Osteoarthritis Index is recommended for the evaluation of treatment effect in persons with osteoarthritis (OA). This is a generic health status questionnaire that contains 36 items, is widely used, and easy to complete. The Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire evaluates the functional status and quality of life (QoL) of patients with any type of knee injury who are at increased risk of developing OA; i.e., patients with anterior cruciate ligament (ACL) injury, meniscus injury, or chondral injury. So far, the KOOS questionnaire has been validated for several orthopedic procedures such as total knee arthroplasty, ACL reconstruction, and meniscectomy. The utilization of QoL questionnaires is crucial to the adequate assessment of a number of orthopedic procedures of the knee. The questionnaires are generally well accepted by the patients and open up new perspectives in the analysis of prognostic factors for optimal QoL of patients undergoing knee surgery
Effects of mineral amendments on trace elements leaching from pre-treated marine sediment after simulated rainfall events
Bauxite extraction by-products (red mud) were used to evaluate their potential ability to stabilize trace elements from dredged and aerated/humidified marine sediment. The investigated by-products were: bauxalineÂź(BX) that is a press-filtered red mud; bauxsolâą(BS) that is a press-filtered red mud previously washed with excess of seawater, and gypsum neutralized bauxalineÂź (GBX). These materials were separately mixed to dredged composted sediment sample considering 5% and 20% sediment: stabilizer ratios. For pilot experiments, rainfall events were regularly simulated for 3 months. Concentrations of As, Mo, Cd, Cr, Zn, Cu, and Ni were analyzed in collected leachates as well as toxicity. Results showed that Cd, Mo, Zn, and Cu were efficiently stabilized in the solid matrix when 20% of BX, BS, and GBX was applied. Consequently, toxicity of leachates was lower than for the untreated sediment, meaning that contaminants mobility was reduced. A 5% GBX was also efficient for Mo, Zn and Cu stabilization. In all scenarios, As stabilization was not improved. Compared to all other monitored elements, Mo mobility seemed to depend upon temperature-humidity conditions during pilot experiments suggesting the need of further investigations
The influence of superstructures on bright galaxy environments: clustering properties
We analyse the dependence of clustering properties of galaxies as a function
of their large-scale environment. In order to characterize the environment on
large scales, we use the catalogue of future virialized superstructures (FVS)
by Luparello et al. and separate samples of luminous galaxies according to
whether or not they belong to FVS. In order to avoid biases in the selection of
galaxies, we have constructed different subsamples so that the distributions of
luminosities and masses are comparable outside and within FVS. As expected, at
large scales, there is a strong difference between the clustering of galaxies
inside and outside FVS. However, this behaviour changes at scales r < 1 Mpc/h,
where the correlations have similar amplitudes. The amplitude of the two-halo
term of the correlation function for objects inside FVS does not depend on
their mass, but rather on that of the FVS. This is confirmed by comparing this
amplitude with that expected from extended Press-Schechter fits. In order to
compare these observational results with current models for structure
formation, we have performed a similar analysis using a semi-analytic
implementation in a LCDM cosmological model. We find that the cross-correlation
functions from the mock catalogue depend on the large-scale structures in a
similar way to the observations. From our analysis, we conclude that the
clustering of galaxies within the typical virialized regions of groups, mainly
depends on the halo mass, irrespective of the large-scale environment.Comment: 12 pages, 9 figures, modified to match accepted version in MNRA
