The optimal periprocedural imaging strategy during transcathether aortic valve replacement (TAVR) performed under moderate sedation is debated. Transthoracic echocardiography (TTE) provides suboptimal views due to poorer resolution and patient positioning, whereas use of transesophageal echocardiography (TEE) under moderate sedation is not widely utilized. The aim of our study was to compare the value of TTE in comparison with TEE guidance under moderate sedation during TAVR. The study population included 144 consecutive patients (mean age 83±11 years, 78(54%) females) who had TAVR under moderate sedation using either a TTE (n=96) or TEE (n=48)...

The genus Leptodrepana Shaw was described in 1983, but prior to the current study only one Neotropical species had been described from Mexico and none were named from Costa Rica. In this paper twenty-four new species are described and named from Costa Rica: L. alexisae Dadelahi & Shaw, sp. n. , L. atalanta Dadelahi & Shaw, sp. n. , L. conda Dadelahi & Shaw, sp. n. , L. conleyae Dadelahi & Shaw, sp. n. , L. demeter Dadelahi & Shaw, sp. n. , L. eckerti Dadelahi & Shaw, sp. n ., L. gauldilox Dadelahi & Shaw, sp...

Purpose: Metformin is one of the most popular drugs tested against nonalcoholic fatty liver disease (NAFLD). The present study aimed to investigate whether calcium-vitamin D3 cosupplementation will intensify the effect of metformin on the prevention of high-fat, high-fructose (HFFr) diet-induced hepatic steatosis. Methods: Male wistar rats (210±16 g) were assigned into the following seven groups: a Control group to receive a standard chow and six HFFr-fed groups to receive diets containing either normal (0...

We derive general equations of motions for highly-confined particles that perform quasi-two-dimensional motion in Hele-Shaw channels, which we solve analytically, aiming to derive design principles for self-steering particles. Based on symmetry properties of a particle, its equations of motion can be simplified, where we retrieve an earlier-known equation of motion for the orientation of dimer particles consisting of disks (Uspal <i>et al.</i>, Nature communications <b>4</b> (2013)), but now in full generality...

OBJECTIVES: The aim of the study was to compare the acute outcomes of Absorb bioresorbable vascular scaffolds (BVS) and second-generation drug-eluting stent (DES) implantation in routine clinical practice. There is a paucity of data regarding BVS use in a real-world patient population. METHODS: The study population comprised 40 consecutive patients who underwent percutaneous coronary intervention (PCI) with BVS implantation at a tertiary-care center in New York, New York between July and December of 2016...

Transcatheter aortic valve replacement (TAVR) has revolutionized the management of patients with symptomatic severe aortic stenosis, and indications are expanding towards treating younger patients with lower-risk profiles. Given the progressive nature of coronary artery disease and its high prevalence in those with severe aortic stenosis, coronary angiography and percutaneous coronary intervention will become increasingly necessary in patients after TAVR. There are some data suggesting that there are technical difficulties with coronary re-engagement, particularly in patients with self-expanding valves that, by design, extend above the coronary ostia...

There have been several studies evaluating the association between vitamin and mineral status and menstrual disturbance. In the present study, we aimed to assess the relationship between the menstrual bleeding pattern and premenstrual syndrome (PMS) symptoms with serum 25-hydroxyvitamin D, and calcium levels in adolescent girls. A cross-sectional study was carried out in 897 high school girls from northeastern Iran. The prevalence of hypocalcaemia, normal serum calcium and hypercalcaemia was 27.1, 59.8 and 13...

OBJECTIVE: To assess the correlation between adaptation to maternal role (AMR) and infant development. BACKGROUND: Maternal role is an important key in infant's care and development. Previous findings demonstrated an inconsistency in the effect of the mother's adaptation on each domain of infant's development.

The mechanisms that fungi use to co-regulate subsets of genes specifically associated with morphogenic states represent a basic unsolved problem in fungal biology. Candida albicans is an important model of fungal differentiation both for rapid interconversion between yeast and hyphal growth forms and for white/opaque switching mechanisms. The Sundstrom lab is interested in mechanisms regulating hypha-specific expression of adhesin genes that are critical for C. albicans hyphal growth phenotypes and pathogenicity...

The detection and quantification of biomarkers is gaining attention in medical research and diagnostics communities. Biomarkers cover a range from gases to biological macromolecules. Because of the nanomolar range levels of typical biomarkers in plasma, blood, urine, exhalation samples, and other biological fluids as well as complex matrix of biological media, adequate sample preparation methods should be used for quantification of biomarkers. The performance of an analytical method for biomarkers should support reproducible and accurate data...

Extraosseous accumulation of technetium-99m-methyl diphosphonate (99m Tc-MDP) on bone scan is not common. This phenomenon is often attributed to abnormality of calcium metabolism and has been reported in a variety of conditions including metabolic diseases and malignancies.

Beet mosaic virus (BtMV), the only Potyvirus known to infect sugar beet, occurs worldwide in beet crops. The full genome sequencing of a BtMV isolate from Iran (Ir-VRU), enabled us to better understand the evolutionary history of this virus. Selection analysis suggested that BtMV evolution is mainly under negative selection but its strength varies in different proteins with the multifunctional proteins under strongest selection. Recombination has played a major role in the evolution of the BtMVs; only the Ir-VRU and USA isolates show no evidence of recombination...

Introduction: Nonfinancial barriers are frequent causes of unmet need in health-care services. The significance of transportation barriers can weigh more than the issues of access to care. The purpose of this cross-sectional study was to examine transportation and other nonfinancial barriers among low-income uninsured patients of a safety net health-care facility (free clinic). Methods: The survey data were collected from patients aged 18 years and older who spoke English or Spanish at a free clinic, which served uninsured individuals in poverty in the United States...

OBJECTIVES: This study sought to examine the safety and performance of contemporary transcatheter aortic valve replacement (TAVR) in an exclusive all-women TAVR population, and to further investigate the potential impact of female sex-specific characteristics on composite 1-year clinical outcomes. BACKGROUND: Women comprise ≥50% patients undergoing TAVR. Several data have shown the noninferiority of TAVR compared with surgical aortic valve replacement for symptomatic significant aortic stenosis, but no study so far has been specifically powered to detect differences by sex...

BACKGROUND: Diabetic patients account for an increasing number of patients undergoing percutaneous coronary intervention (PCI). However, diabetes mellitus (DM) is associated with increased residual platelet activity during dual antiplatelet treatment (DAPT) and DM patients have worse clinical outcomes after PCI as compared to non-DM.

We develop a lattice-based Monte Carlo simulation method for charged mixtures capable of treating dielectric heterogeneities. Using this method, we study oil-water mixtures containing an antagonistic salt, with hydrophilic cations and hydrophobic anions. Our simulations reveal several phases with a spatially modulated solvent composition, in which the ions partition between water-rich and water-poor regions according to their affinity. In addition to the recently observed lamellar phase, we find tubular and droplet phases, reminiscent of those found in block copolymers and surfactant systems...
