Echocardiography Core Laboratory Methodology for TAVR: A Transatlantic Consensus.

Inter-echocardiography core laboratory (ECL) harmonization is pivotal to consider data from different ECLs interchangeable. On the basis of the experience of the first trans-Atlantic harmonization of 2 established ECLs in the field of transcatheter aortic valve replacement (TAVR) trials, this review describes the harmonized ECL methodology in analyzing and adjudicating the post-TAVR echocardiographic endpoints according to Valve Academic Research Consortium 3 definitions. This review presents the feasibility and intra- and inter-ECL reproducibility, explains the root cause of potential important inter-ECL variability, and formulates ECL recommendations for optimal post-TAVR echocardiographic image acquisition.

Orbital variations as a major driver of climate and biome distribution during the greenhouse to icehouse transition.

Recent studies suggest increasing sensitivity to orbital variations across the Eocene-Oligocene greenhouse to icehouse climate transition. However, climate simulations and paleoenvironmental studies mostly provide snapshots of the past climate, therefore overlooking the role of this short-term variability in driving major environmental changes and possibly biasing model-data comparisons. We address this problem by performing numerical simulations describing the end-members of eccentricity, obliquity, and precession.

Management of an Intrauterine Device Migration Resulting in a Pregnancy - Clinical Case.

Intrauterine devices (IUD) are one of the most commonly used methods of contraception worldwide. The long term effect makes it desirable by most patients. The insertion of an IUD is not difficult as a technique but it involves multiple complications such as uterine perforation and migration into the abdominal cavity, urinary bladder perforation, fistula formation, bowel perforation and intra-abdominal adhesions.

The Vision of Managing for Pest-Resistant Landscapes: Realistic or Utopic?

Purpose Of Review: Forest managers have long suggested that forests can be made more resilient to insect pests by reducing the abundance of hosts, yet this has rarely been done. The goal of our paper is to review whether recent scientific evidence supports forest manipulation to decrease vulnerability. To achieve this goal, we first ask if outbreaks of forest insect pests have been more severe in recent decades.

Cenozoic evolution of the steppe-desert biome in Central Asia.

The origins and development of the arid and highly seasonal steppe-desert biome in Central Asia, the largest of its kind in the world, remain largely unconstrained by existing records. It is unclear how Cenozoic climatic, geological, and biological forces, acting at diverse spatial and temporal scales, shaped Central Asian ecosystems through time. Our synthesis shows that the Central Asian steppe-desert has existed since at least Eocene times but experienced no less than two regime shifts, one at the Eocene-Oligocene Transition and one in the mid-Miocene.

Muon reconstruction efficiency and momentum resolution of the ATLAS experiment in proton-proton collisions at [Formula: see text] TeV in 2010.

This paper presents a study of the performance of the muon reconstruction in the analysis of proton-proton collisions at [Formula: see text] TeV at the LHC, recorded by the ATLAS detector in 2010. This performance is described in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons. The results are obtained from an analysis of [Formula: see text] meson and [Formula: see text] boson decays to dimuons, reconstructed from a data sample corresponding to an integrated luminosity of 40 pb[Formula: see text].

A measurement is presented of the [Formula: see text] production cross section at [Formula: see text] = 7 TeV using [Formula: see text] collision data corresponding to an integrated luminosity of 383 [Formula: see text], collected with the ATLAS experiment at the LHC. Selection of [Formula: see text](1020) mesons is based on the identification of charged kaons by their energy loss in the pixel detector. The differential cross section is measured as a function of the transverse momentum, [Formula: see text], and rapidity, [Formula: see text], of the [Formula: see text](1020) meson in the fiducial region 500 [Formula: see text] 1200 MeV, [Formula: see text] 0.

Gonioscopic findings associated with a positive dark-room provocative test in narrow angles after laser iridotomy.

Purpose: To determine clinical factors and ultrasound biomicroscopic (UBM) findings associated with a positive prone dark-room provocative test (DRPT) in patients with narrow angles after laser peripheral iridotomy (LPI).

Patients And Methods: Seventeen eyes with a positive DRPT and 18 eyes with a negative DRPT were included in this comparative case series, based on chart review of patients diagnosed with narrow angles persisting after LPI who had undergone clinical evaluation with a 45-minute DRPT and UBM imaging. Subjects with a positive DRPT [an increase of intraocular pressure (IOP) of 6 mm Hg or more] were compared with a negative DRPT control group.

Observation of associated near-side and away-side long-range correlations in sqrt[s(NN)]=5.02 TeV proton-lead collisions with the ATLAS detector.

[PROSPERE randomized controlled trial: laparoscopic sacropexy versus vaginal mesh for cystocele POP repair].

Background: Cystocele is a frequent and invalidating type of genital prolapse in woman. Sacropexy using synthetic mesh is considered the surgical gold standard, and the laparoscopic approach has supplanted the open abdominal route because it offers the same anatomical results with a lower morbidity. The use of mesh through the vaginal route may have many advantages: easiness to perform, shorter operative time and recovery, but may increase morbidity.
