Abstract
Abstract
Background
Transcatheter mitral valve repair with MitraClip is effective for patients with mitral regurgitation (MR) and high or prohibitive surgical risk. Global longitudinal strain (GLS) allows evaluation of subclinical myocardial dysfunction, but its incremental clinical utility is unknown in patients treated with MitraClip.
Purpose
To evaluate the relation of baseline GLS and 1-year combined endpoint of all-cause death and heart failure hospitalization in patients treated with MitraClip.
Methods
We analyzed all patients who underwent MitraClip in our hospital between 2012 and 2018. Baseline LV GLS was obtained by 2D speckle tracking echocardiography, averaging the 18-segments from 3 apical views. Receiver operating characteristic (ROC) analyses were used to assess GLS cut-point associated with mortality. Multivariate models with Cox regression tested its relationship after adjustment of baseline characteristics.
Results
We examined 155 patients (mean age 83±7 years, 52% men; mean LVEF 56±10%, the Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM) for repair 6.62±5.22%). At one-year, there were 30 deaths and 9 of heart failure hospitalizations, totalizing a composite outcome rate of 25.2%. Baseline GLS (per 1% increase) was associated with 1-year combined endpoint before (HR 1.10, 95% CI 1.02–1.19, p=0.02) and after (HR 1.10, 95% CI 1.01–1.20, p=0.04, respectively) adjustment for baseline characteristics. The optimal value of GLS for discriminating mortality at 1-year was −14.5% (AUC, 0.60; sensitivity 40%, specificity 76%). After accounting for baseline characteristics, patients with reduced GLS (>−14.5%) had worse 1-year combined endpoint than those with preserved GLS (≤−14.5%) (p<0.001; Figure).
Conclusions
Baseline GLS is independently associated with 1-year combined endpoint of all-cause mortality and/or heart failure hospitalization in patients who received transcatheter mitral valve repair. Detection of subclinical myocardial dysfunction by GLS may improve risk stratification and long-term success in these patients.

Abstract
Pesticides guarantee us high productivity in agriculture, but the long-term costs have proved too high. Acute and chronic intoxication of humans and animals, contamination of soil, water and food are the consequences of the current demand and sales of these products. In addition, pesticides such as glyphosate are sold in commercial formulations which have inert ingredients, substances with unknown composition and proportion. Facing this scenario, toxicological studies that investigate the interaction between the active principle and the inert ingredients are necessary. The following work proposed comparative toxicology studies between glyphosate and its commercial formulation using the alternative model Caenorhabditis elegans. Worms were exposed to different concentrations of the active ingredient (glyphosate in monoisopropylamine salt) and its commercial formulation. Reproductive capacity was evaluated through brood size, morphological analysis of oocytes and through the MD701 strain (bcIs39), which allows the visualization of germ cells in apoptosis. In addition, the metal composition in the commercial formulation was analyzed by ICP-MS. Only the commercial formulation of glyphosate showed significant negative effects on brood size, body length, oocyte size, and the number of apoptotic cells. Metal analysis showed the presence of Hg, Fe, Mn, Cu, Zn, As, Cd and Pb in the commercial formulation, which did not cause reprotoxicity at the concentrations found. However, metals can bioaccumulate in soil and water and cause environmental impacts. Finally, we demonstrated that the addition of inert ingredients increased the toxic profile of the active ingredient glyphosate in C. elegans, which reinforces the need of components description in the product labels.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Verbena montevidensis and Verbena litoralis are plants that present morphological similarities. They are both known as "gervão" and "fel-da-terra", among other popular names, and are used in folk medicine to treat diseases related to the liver and stomach. AIMS OF THE STUDY The aim of the current investigation was to determine the chemical composition and evaluate the hepatoprotective properties and cytotoxicity of the methanolic and aqueous extracts of V. montevidensis, V. litoralis and their main iridoid in HepG2 cells. MATERIALS AND METHODS Aqueous and methanolic extracts from the dried aerial parts of V. montevidensis and V. litoralis were obtained. The methanolic extract of V. montevidensis afforded an iridoid as the main compound. The extracts and isolated compound were examined for the hepatoprotective effect and cytotoxicity in human hepatoblastoma HepG2 cells by MTT reduction and neutral red uptake methods. RESULTS The methanolic and aqueous extracts of both species showed the presence of iridoid and phenylethanoids as the main compounds. The iridoid brasoside was isolated and identified by spectroscopic methods. The phenylethanoid was characterized by HPLC, comparing the UV profile and retention time with an authentic sample. The results of the biological assays indicate that both aqueous and methanolic extracts of V. montevidensis and V. litoralis as well as brasoside were hepatoprotective against ethanol-induced damage in HepG2 cells. The effect can be attributed to the main compounds present since both classes are recognized for this activity. CONCLUSIONS Our results contribute towards validation of the traditional use of V. montevidensis and V. litoralis in the treatment of liver disorders.

Abstract
A retrospective cohort study was performed to examine whether, in artificial endometrial preparation for frozen embryo transfer (FET) cycles, progesterone (P) levels the day prior to embryo transfer of euploid embryos have an impact on pregnancy outcomes. In a private university clinic, 244 FETs between January 2016 and June 2017 were analyzed. Endometrial preparation was achieved with estradiol valerate and vaginal micronized progesterone. Serum P and estradiol levels the day prior to embryo transfer were measured. A multivariable analysis to assess the relationship between serum P level and pregnancy outcomes was performed, adjusted for confounding variables. Mean P value was 11.3 ± 5.1 ng/ml. Progesterone levels were split in quartiles: Q1: ≤ 8.06 ng/ml; Q2: 8.07-10.64 ng/ml; Q3: 10.65-13.13 ng/ml; Q4: > 13.13 ng/ml. Patients included in the lower P quartile had a significantly higher miscarriage rate and significantly lower live birth rate (LBR) compared to the higher ones. A low serum P level (≤ 10.64 ng/ml) one day before FET is associated with a lower pregnancy and LBR following FET of euploid embryos.

Abstract
We measure the quantum fluctuations of a single acoustic mode in a volume of superfluid He that is coupled to an optical cavity. Specifically, we monitor the Stokes and anti-Stokes light scattered by a standing acoustic wave that is confined by the cavity mirrors. The intensity of these signals (and their cross-correlation) exhibits the characteristic features of the acoustic wave's zero-point motion and the quantum backaction of the intracavity light. While these features are also observed in the vibrations of solid objects and ultracold atomic gases, their observation in superfluid He opens the possibility of exploiting the remarkable properties of this material to access new regimes of quantum optomechanics.

Abstract
Abstract
Background: TAILORx patient-reported outcomes (PRO) quantify symptoms and health-related quality of life (HRQL) from C+E beyond E alone from the patient's perspective, thus can inform decision-making for women in the intermediate risk group for whom chemotherapy may still be considered.
Methods: TAILORx participants with OncoType DX Recurrence Scores 11-25 were randomly assigned to E or C+E. All TAILORx participants enrolled 1/2010-10/2010 (N=612) completed PROs measuring fatigue, endocrine symptoms, cognitive impairments (PCI), and fear of recurrence at baseline, 3, 6, 12, 24 and 36 months. HRQL was assessed at baseline, 12, and 36 months. Linear regression (LR) examined PRO scores among the per-protocol sample.
Results: Overall, participants reported significantly more fatigue, endocrine symptoms and PCI at 3, 6, 12, 24 and 36 months compared to baseline and those randomized to C+E reported a greater magnitude of change baseline-3 months compared to those randomized to E alone (Table 1). Overall, by 12 months symptoms were comparable between groups. Pre-menopausal women had comparable symptoms at 24 and 36 months. Post-menopausal women randomized to C+E had greater endocrine symptoms at 24 and 36 months and greater fatigue at 6 and 24 months. Fear of recurrence was comparable between arms during treatment and follow-up. Multiple linear regression identified increased fatigue (LR slope β=0.67), endocrine symptoms (β =0.14), and PCI (β=0.11) as significant predictors of decreased HRQL across arms (p< 0.001). HRQL was comparable between E and C+E at 12- and 36-months.

Conclusions: TAILORx is the first trial to examine patient-reported fatigue, endocrine symptoms, PCI and HRQL among breast cancer patients randomized to endocrine therapy alone vs chemoendocrine therapy, thus allowing us to quantify acute and long-term symptoms uniquely attributable to chemotherapy. As expected, chemotherapy is associated with greater fatigue, endocrine symptoms and PCI acutely during treatment, and for post-menopausal women with greater long-term endocrine symptoms. Increased symptoms were associated with poorer HRQL. Long-term HRQL was comparable between groups.

Abstract
ABSTRACT In the present study, histological, morphometrical and ultrastructural analysis were performed to investigate intestinal mucosa changes in piglets jejunal explants exposed to two concentration of heat-inactivated Lactobacillus plantarum and their respective culture supernatants. Jejunal explants were incubated for 4 hours in DMEM culture medium with a) only culture medium (control group), b) heat-inactivated Lactobacillus plantarum strain1 - LP1 (1.1 x 108CFU/ml), c) heat-inactivated Lactobacillus plantarum strain2 - LP2 (2.0 x 109CFU/ml), d) heat-inactivated Lactobacillus plantarum strain1 culture supernatant (CS1), and e) heat-inactivated Lactobacillus plantarum strain2 culture supernatant (CS2). Explants exposed to heat-inactivated L. plantarum strain 1 and 2 showed multifocal to difuse villi atrophy, villi apical necrosis and enterocyte flattening. Morphological assessment revealed similar results with bacterial adhesion to mucus and intestinal epithelial cells and, morphometric analysis showed a decreased villi height compared to the control group. Alterations in explants treated with the culture supernatant of both strains include mild villi atrophy and mild enterocyte apical necrosis. Morphological assesment reveled numerous well delineated villi and, morphometric analysis showed a significant increase in villi height compared to the control group. In general, exposure to the culture supernatants improved the intestinal morphology.

Abstract
We investigate the large length and long time scales collective flows and structural rearrangements within in vitro human bronchial epithelial cell (HBEC) cultures. Activity-driven collective flows result in ensembles of vortices randomly positioned in space. By analyzing a large population of vortices, we show that their area follows an exponential law with a constant mean value and their rotational frequency is size independent, both being characteristic features of the chaotic dynamics of active nematic suspensions. Indeed, we find that HBECs self-organize in nematic domains of several cell lengths. Nematic defects are found at the interface between domains with a total number that remains constant due to the dynamical balance of nucleation and annihilation events. The mean velocity fields in the vicinity of defects are well described by a hydrodynamic theory of extensile active nematics.

Abstract
In the present study, histological, morphometrical and ultrastructural analysis were performed to investigate intestinal mucosa changes in piglets exposed to deoxynivalenol alone or associated with two strains of Lactobacillus plantarum and the respective culture supernatants. Jejunal explants were incubated for 4h in culture medium with a) only culture medium (DMEM, control group), b) deoxynivalenol (DON, 10μM), c) heat-inactivated Lactobacillus plantarum strain1 - LP1 (1.1×108 CFU/ml) plus DON, d) heat-inactivated Lactobacillus plantarum strain2-LP2 (2.0×109 CFU/ml) plus DON, e) heat-inactivated Lactobacillus plantarum strain1 culture supernatant (CS1) plus DON, and f) heat-inactivated Lactobacillus plantarum strain1 culture supernatant (CS1) plus DON. Explants exposed to DON and DON plus LP1 and LP2 showed a significant increase in histological changes (mainly villi atrophy and apical necrosis) and a significant decrease in villi height when compared to unexposed explants. However, explants treated with CS1+DON and CS2+DON remained similar to the control group both in histological and morphometrical aspects. DON also induced a significant decrease in goblet cell density compared to control whereas CS1+DON treatment induced an increase in the number of goblet cells in comparison to DON explants. In addition, ultrastructural assessment showed control, CS1+DON and CS2+DON explants with well delineated finger shape villi, meanwhile DON-treated, LP1+DON and LP2+DON explants showed a severe villi atrophy with leukocytes exudation on the intestinal surface. Taken together, our results indicate that the culture supernatant treatment reduced the toxic effects induced by DON on intestinal tissue and may contribute as an alternative strategy to reduce mycotoxin toxicity.
