Abstract

This study proposes an empirical model to investigate the inter-relations among Corporate Social Responsibility (CSR), Corporate Financial Performance (CFP) and size, while accounting for liquidity and exposure to financial default risk. The analytical focus lies on potential endogeneity issues, which are investigated employing a system of equations, estimated using the Generalized Method of Moments (GMM) technique. A non-industry-specific sample is employed, consisting of 233 companies included in FTSE 250, from 2003 to 2010. The main findings strongly indicate that UK market is sensitive to firms' social profiles, which are found to be endogenous related to both size and performance. Furthermore, CSR is asymmetrically related to performance, where excessive or no investment in CSR are the most rewarding financially. This supports the hypothesis in Barnett and Salomon (2012) that the relationship between corporate social performance and corporate financial performance follows a U-shaped pattern. We also find larger and more profitable companies are more likely to invest in CSR, which in turn further contributes to both, probably due to increased visibility. This is a strong indication that size might be a significant determinant of the shape of the CSR-CFP relationship and that CSR activities constitute a long term investment.

Abstract

Abstract Background The diagnosis of acute cellular rejection (ACR) is a major objective in the management of heart transplant recipients. The aim of this study was to assess the utility of speckle-tracking derived parameters in identifying patients at risk of graft rejection. Methods A prospective, single-center study was carried out involving 45 consecutive heart transplant patients who underwent a total of 220 routine endomyocardial biopsies (EMBs) with correlative echocardiographic examination. Results No significant ACR (grade 0-1R) was seen in 190 biopsies (81.2% of the ACR-free group), and moderate ACR requiring specific treatment (grade 2R) was detected in 30 biopsies (13.6% of the ACR group). Grade 3R was not observed. All longitudinal left ventricular (LV) and right ventricular (RV) strain parameters were greater in the ACR-free group than in patients with ACR, while no differences were observed between radial and circumferential strain parameters. In our analysis, we selected RV free wall longitudinal strain (RV FW) ≤ 16.8% and 4-chamber longitudinal strain (4CH LS) ≤ 13.8%, which related to the presence of ACR requiring treatment. We assigned 1 point for each parameter (minimum 0, maximum 2 points) and derived a new echocardiographic index, the Strain Rejection Score (SRS). Our proposed approach—a combination of the 2 abovementioned indices—for screening patients at risk of ACR ≥ 2R, when expressed by a score 2 points, showed good specificity, strong negative predictive value, and the highest area under the curve. Conclusions Our study demonstrated that combination of 4CH LS and RV FW as a new echocardiographic index, the Strain Rejection Score, can be useful as a noninvasive assessment of ACR during the first year of follow-up after heart transplant. Highlights • Noninvasive detection of rejection is a major objective in the management of heart transplant recipients. • We evaluated a new echocardiographic index, Strain Rejection Score (SRS), in the assessment of cardiac allograft rejection. • The new index includes RV free wall longitudinal strain and 4-chamber longitudinal strain analysis. • According to our results, SRS is sufficient for use as an auxiliary diagnostic tool for identifying most patients with a high degree of ACR suspicion.

41. The Solvus Curve for Guinier–Preston Zones in Al–Zn Alloys: A Diffuse X-Ray Study

Author

Niklewski, T., Spiegelberg, P., and Sunbulli, K.

Abstract

A diffuse X-ray scattering study has been carried out on two aluminium–zinc alloys, one containing 15 wt.-% zinc and the other 25 wt.-%. Both were examined after water-quenching and ageing for different times at different temperatures. The results support a proposal made by Lasek (Physica Status Solidi, 1964, 5, K117) regarding the solvus curve for Guinier–Preston zones in aluminium–zinc alloys. The curve by Borelius (J. Metals, 1951, 3, 477) appears to be a lower limit for the transformation (after prolonged ageing) of completely coherent Guinier–Preston zones to partially coherent zones.

Abstract

Aims: In recent years, survival in patients with breast cancer has increased. Despite the improvement in outcomes of those patients, the risk of treatment-related cardiotoxicity remains high, and its presence has been associated with a higher risk of treatment termination and thus lower therapeutic efficacy. Prior trials demonstrated that a preventive initiation of heart failure drugs, including the renin-angiotensin-aldosterone inhibitors, might reduce the risk of treatment-related cardiotoxicity. However, to date, no study investigated the efficacy of sacubitril/valsartan, a novel antineurohormonal drug shown to be superior to the previous therapies, in the prevention of cardiotoxicity in patients with early-stage breast cancer, which is the aim of the trial., Methods and Results: MAINSTREAM is a randomized, placebo-controlled, double-blind, multicentre, clinical trial. After the run-in period, a total of 480 patients with early breast cancer undergoing treatment with anthracyclines and/or anti-human epidermal growth factor receptor 2 drugs will be randomized to the highest tolerated dose of sacubitril/valsartan, being preferably 97/103 mg twice daily or placebo in 1:1 ratio. The patients will be monitored, including routine transthoracic echocardiography (TTE) and laboratory biomarker monitoring, for 24 months. The primary endpoint of the trial will be the occurrence of a decrease in left ventricular ejection fraction by ≥5% in TTE within 24 months. The key secondary endpoints will be the composite endpoint of death from any cause or hospitalization for heart failure, as well as other imaging, laboratory, and clinical outcomes, including the occurrence of the cancer therapy-related cardiac dysfunction resulting in the necessity to initiate treatment. The first patients are expected to be recruited in the coming months, and the estimated completion of the study and publication of the results are expected in December 2027, pending recruitment., Conclusions: The MAINSTREAM trial will determine the efficacy and safety of treatment with sacubitril/valsartan as a prevention of cardiotoxicity in patients with early breast cancer (ClinicalTrials.gov number: NCT05465031)., (© 2023 The Authors.

Abstract

Introduction: Indications for transcatheter aortic valve implantation (TAVI) are constantly expanding, including younger patients. Bicuspid aortic valves (BAV) often occur in this group. In order to achieve optimal treatment results in younger patients, it is necessary to develop an effective method for selecting the size of implanted valves., Aim: To compare the results of TAVI with use of a self-expanding prosthesis in patients with a BAV and a tricuspid aortic valve (TAV) with valve selection based on annular sizing., Material and Methods: The diagnosis of BAV and TAV and measurements (annular sizing) were based on multi-slice computed tomography scans. Eighty-three patients received a self-expanding CoreValve or Evolut R prosthesis. In group I (BAV) there were 21 (25.3%) patients and in group II (TAV) there were 62 (74.7%) patients., Results: The groups did not differ in terms of baseline clinical characteristics. Device success was achieved in 16 (76.2%) and 55 (88.7%) ( p = NS) in group I and II respectively. Composite endpoints: early safety occurred in 5 (23.8%) and 11 (17.7%) patients ( p =NS) in group I and II respectively; clinical efficacy occurred in 10 (47.6%) and 28 (45.2%) patients ( p = NS) in group I and II respectively. 30-day mortality was 4.8% vs 9.7%, 1-year mortality was 28.6% vs 17.7% ( p = NS) in group I and II respectively., Conclusions: TAVI in patients with severe aortic stenosis and BAV is as effective as in patients with TAV using self-expanding prostheses if the valve selection is based on annular sizing., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2021 Termedia Sp. z o. o.)

Abstract

Less-invasive left ventricular assist device implantation is becoming the technique of choice for implementation of new-generation heart pumps. The less-invasive technique is particularly useful for patients with a history of cardiac surgical procedures, such as coronary artery bypass grafting. Yet, in redo cases, severe pericardial adhesions may force experienced operators to opt for alternative outflow graft placement, such as in the descending aorta. We propose a surgical technique in which the left ventricular device is implanted through a limited thoracic incision, with the outflow graft anastomosed to the ascending aorta, avoiding collision with coronary bypass grafts. The key element of the proposed technique is a tunnel connecting 2 pleural cavities, in which the outflow graft is placed, entirely bypassing the pericardium., (© The Author(s) 2018.

Abstract

Introduction: The presence of coronary artery disease (CAD) in patients who underwent transcatheter aortic valve implantation (TAVI) may increase in-hospital and long-term mortality., Aim: To evaluate the impact of CAD in patients who underwent TAVI., Material and Methods: The study group consisted of the first 142 patients treated with TAVI between 26 November 2008 and 31 December 2015. The patients were divided into two groups: group I comprised 103 (72.5%) patients with CAD, and group II comprised 39 (27.5%) patients without CAD., Results: Group I was characterized by a significantly higher risk according to EuroSCORE - 11.2 ±2.5 vs. 9 ±2.3 in group II ( p < 0.001) and Logistic EuroSCORE - 25.4 ±13.4 vs. 16.3 ±8.7 ( p < 0.001). 30-day mortality was 8 (7.8%) vs. 2 (5.1%) ( p = NS) and 1-year mortality was 22 (21.4%) vs. 6 (15.4%) ( p = NS) in group I and II respectively. The composite endpoint evaluating the efficacy of TAVI was achieved in 82 (79.6%) vs. 31 (79.5%) ( p = NS) in group I and II respectively. The composite endpoint, which involved 30-day observation, occurred in 39 (37.86%) vs. 12 (30.77%) ( p = NS) and the composite endpoint, which involved 1-year evaluation of the clinical efficacy of TAVI, occurred in 48 (57.8%) vs. 13 (48.1%) ( p = NS) in patients with and without CAD respectively., Conclusions: The short- and mid-term outcomes of TAVI patients with CAD, despite higher risk profile, did not differ from the outcomes of treatment in patients without CAD., Competing Interests: The authors declare no conflict of interest.

Abstract

BACKGROUND Recent advances in ultrasound strain imaging facilitate more precise monitoring of subtle myocardial changes and thus may allow for more appropriate assessment of myocardium after orthotopic heart transplantation (OHT). This study aimed to explore longitudinal left ventricular (LV) and right ventricular (RV) function by speckle-tracking echocardiography (STE) during a 12-month follow-up period in relation to acute cellular rejection (ACR) degree ≥2R and the response to intense immunosuppressive therapy with intravenous steroids. MATERIAL AND METHODS Forty-five adult heart transplant recipients were prospectively assessed at a single center from January 2016 until June 2017. Echocardiography was performed serially at baseline and together with routine biopsies at 2 weeks and 1, 2, 3, 6, 9, and 12 months after OHT. Changes in graft function were evaluated using STE before and during ACR and in the resolving period of ACR. RESULTS A total of 220 pairs of biopsy specimens and strain recordings were analyzed. Moderate ACR was seen in 30 biopsies (13.6%). In the serial assessment, longitudinal strain parameters of the LV (global and 4-, 2-, 3-chamber longitudinal strain) and RV (global and free wall longitudinal strain) were decreased at baseline and improved significantly (P<0.001) within 12 months after OHT. The degree of improvement was not influenced by ACR. There were no significant differences in circumferential, radial, or longitudinal strain rate, or mechanical dyssynchrony. Reduced LV and RV longitudinal strain was related to ACR degree 2R and increased significantly (P<0.0005) during 3 days of intravenous methylprednisolone therapy. CONCLUSIONS Using the STE technique, we have documented an acute improvement in mechanical myocardial function following ACR steroid therapy and a progressive recovery of LV and RV longitudinal function during the first year after OHT.

Abstract

Introduction: Epiaortic ultrasound scanning (EAS) extended the use of ultrasound to the intraoperative diagnosis of aortic pathology. Surgical palpation of the ascending aorta underestimates the presence and severity of atherosclerotic plaques. Epiaortic ultrasound scanning has been used as an adjunct to transesophageal echocardiography (TEE) or as a primary direct diagnostic tool for imaging the ascending aorta as well as the aortic arch, which gained prominence as part of a multipronged intraoperative strategy to reduce atherosclerotic emboli., Aim: To compare the epiaortic examination with transthoracic and transesophageal echo (transthoracic echocardiography (TTE) and TEE), X-ray, surgical intraoperative palpation, and postoperative neurological status., Material and Methods: The analyzed group consisted of 35 patients (mean age: 81.3 years) treated with aortic valve replacement (AVR), either alone (60%) or combined with coronary artery bypass grafting (CABG; 22.8%) or aortic aneurysm replacement (11.42%). In 2 patients, only CABG was performed because intraoperatively reevaluated strategy. Thierteen patients have got a history of diabetes, 10 chronic renal failure and 3 of cerebral stroke., Results: In more than 80% of patients, positive EAS results had an influence on the choice of aortic clamping site and in 50% of patients on the site of cannulation. Female sex, peripheral vascular disease, history of previous stroke, and calcifications in the ascending aorta in TTE have significant predictive value for recognizing atherosclerotic changes in EAS and the risk of postoperative neurological complications in octogenarians treated with AVR., Conclusions: Epiaortic ultrasound scanning imaging is superior to TTE and manual palpation in the detection and localization of ascending atherosclerosis. This technique should be introduced as a standard perioperative examination in older patients at risk of neurological complications., Competing Interests: The authors report no conflict of interest.

Abstract

Introduction: Hybrid ablation (HABL) of atrial fibrillation combining endoscopic, minimally invasive, closed chest epicardial ablation with endocardial CARTO-guided accuracy was introduced to overcome the limitations of current therapeutic options for patients with persistent (PSAF) and longstanding persistent atrial fibrillation (LSPAF). The purpose of this study was to evaluate the procedural safety and feasibility as well as effectiveness of HABL in patients with PSAF and LSPAF 1 year after the procedure., Material and Methods: The study is a single-center, prospective clinical registry. From 07/2009 to 12.2014, 90 patients with PSAF ( n = 39) and LSPAF ( n = 51), at the mean age of 54.8 ±9.8, in mean EHRA class 2.6, underwent HABL. 64.4% of patients had a history of prior cardioversion or catheter ablation. Thirteen patients had LVEF less than 35%. Mean AF duration was 4.5 ±3.7 years. Patients were scheduled for 3-, 6- and 12-month follow-up with 7-day Holter monitoring., Results: At 6 months after the procedure 78% (54/69) of patients were in SR. At 12 months after the procedure 86% (59/69) were in SR and 62.3% (43/69) in SR and off class I/III antiarrhythmic drugs (AADs). Only 1% (1/69) of patients required a repeat ablation for atrial flutter. A significant decrease in LA dimension and an increase in LVEF were noted., Conclusions: A combination of epicardial and endocardial RF ablation should be considered as a treatment option for patients with persistent and long-standing persistent atrial fibrillation as it is safe and effective in restoring sinus rhythm., Competing Interests: Michal Zembala MD PhD served as a consultant (proctor) for nContact Inc. from January 2012 until January 2013. Other authors report no conflicts of interests. No corporate funding supported the study. The Reveal XT implantable loop monitors were purchased from funds received from the Polish Society of Cardiology/Servier Prize for the Best Research Proposal in 2011.
