Effects of enriched artemia on growth and survival of juvenile freshwater crayfish (Astacus leptodactylus Esch. 1823)

The experiment was conducted to investigate the effects of artemia enriched with lipid emulsions containing highly unsaturated fatty acids on growth and survival of juvenile freshwater crayfish Astacus leptodactylus. Juvenile crayfish were fed artemia enriched with commercial emulsions (red pepper and olio ω3) and un-enriched artemia (control). The highest eicosapentaenoic acid (EPA) level was found in artemia enriched with olio ω3 (3.17%) and the highest docosahexaenoic acid (DHA) level was found in artemia enriched with red pepper (3.56%). The weight gain, specific growth, and survival rates of juvenile crayfish increased with increasing amount of EPA and DHA in dietary artemia respectively (0.04%, 2.32%). Finally, the juveniles fed with artemia enriched with olio ω3 and red pepper had a better weight gain, specific growth rate, and survival than those fed with un-enriched artemia (p<0.05)

TCT-126 Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention of the Left Anterior Descending Artery

Background: Improvement of left ventricular ejection fraction (LVEF) after chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been modest in prior studies. Methods: Our cohort included patients who underwent LAD CTO PCI at a single center (Henry Ford Hospital) from 2014 to 2021. We evaluate the change in LVEF after LAD CTO PCI using the paired t test in all patients, those with ischemic cardiomyopathy (CM), and those who underwent a viability test. Results: From December 2014 to February 2022, a total of 237 LAD CTO PCI procedures were performed at Henry Ford Hospital (proximal LAD: 56.6%). In-hospital MACE occurred in 13 patients (5.5%; death: 1.3%). Landmark analysis after discharge showed an overall survival of the cohort was 92.7% and MACE-free survival of 85.0% over a median follow-up of 2 years. The median baseline EF was 50% (IQR 35%-55%). Only 51 patients had reduced baseline LVEF (40% or less). After a median follow-up of 9.2 months (IQR 3-28.6 months), there was a significant improvement in LVEF after LAD CTO PCI (mean 10.9%, 95% CI 7.1%-14.8%, P \u3c 0.001). When limiting the analysis to patients who had ischemic cardiomyopathy, proximal LAD CTO PCI, and were on optimal medical therapy (n = 29), LVEF was significantly improved (mean increase of 14%, 95% CI 9.5-18.5%, P \u3c 0.001) after a median follow-up period of 6.2 months (3-29.5 months). Conclusion: LAD CTO PCI was associated with a significant 10% improvement in LVEF in ICM patients and was more pronounced (14% improvement) in those who had proximal LAD treated and were on optimal medical therapy.

Effects of adrenalin on ovarian injury formed by ischemia reperfusion in rats

In this study, the impacts of adrenalin on ovarian injury caused by ischemia reperfusion were investigated in rats. In addition, it’s been investigated whether there is a correlation between adrenergic receptors and oxidant/anti-oxidant and COX1/COX-2 levels. It’s been observed that the COX-2 level that is responsible for MDA and inflammatory reaction (which are the indicators of oxidative stress in ovarian tissue to which ischemia reperfusion was applied) increased and the COX-1 levels that are responsible for GSH (an endogenic anti-oxidant with protective impact) were depressed. Adrenalin has prevented an increase in MDA and COX-2 activity in the ovarian tissue, to which I/R was applied, and prevented a reduction in GSH and COX-1 activity. However, adrenalin failed to prevent an MDA increase in ovarian tissue, to which alpha-2 adrenergic receptor blocker yohimbine was given (I/R formed), and also failed to prevent a GSH and COX-1 decrease. Adrenalin also failed to inhibit the COX-2 activity increase in ovarian tissue, to which beta blocker was applied. As a result, stimulation of the alpha-2 adrenergic receptors in an ovarian tissue causes an anti-oxidant and protective effect, while stimulation of beta-2 adrenergic receptors causes an anti-inflammatory effect. It’s been thought that adrenalin protects the ovarian tissue against ischemia reperfusion by stimulating the alpha-2 and beta-2 adrenergic receptors.Colegio de Farmacéuticos de la Provincia de Buenos Aire

Identification of novel neutralizing single-chain antibodies against vascular endothelial growth factor receptor 2

Human vascular endothelial growth factor (VEGF) and its receptor (VEGFR-2/kinase domain receptor [KDR]) play a crucial role in angiogenesis, which makes the VEGFR-2 signaling pathway a major target for therapeutic applications. In this study, a single-chain antibody phage display library was constructed from spleen cells of mice immunized with recombinant human soluble extracellular VEGFR-2/KDR consisting of all seven extracellular domains (sKDR D1-7) to obtain antibodies that block VEGF binding to VEGFR-2. Two specific single-chain antibodies (KDR1.3 and KDR2.6) that recognized human VEGFR-2 were selected; diversity analysis of the clones was performed by BstNI fingerprinting and nucleotide sequencing. The single-chain variable fragments (scFvs) were expressed in soluble form and specificity of interactions between affinity purified scFvs and VEGFR-2 was confirmed by ELISA. Binding of the recombinant antibodies for VEGFR-2 receptors was investigated by surface plasmon resonance spectroscopy. In vitro cell culture assays showed that KDR1.3 and KDR2.6 scFvs significantly suppressed the mitogenic response of human umbilical vein endothelial cells to recombinant human VEGF 165 in a dose-dependent manner, and reduced VEGF-dependent cell proliferation by 60% and 40%, respectively. In vivo analysis of these recombinant antibodies in a rat cornea angiogenesis model revealed that both antibodies suppressed the development of new corneal vessels (p &lt; 0.05). Overall, in vitro and in vivo results disclose strong interactions of KDR1.3 and KDR2.6 scFvs with VEGFR-2. These findings indicate that KDR1.3 and KDR2.6 scFvs are promising antiangiogenic therapeutic agents. © 2011 International Union of Biochemistry and Molecular Biology, Inc

Angiographic Features and Clinical Outcomes of Balloon Uncrossable Lesions during Chronic Total Occlusion Percutaneous Coronary Intervention

Background: Balloon uncrossable lesions are defined as lesions that cannot be crossed with a balloon after successful guidewire crossing. Methods: We analyzed the association between balloon uncrossable lesions and procedural outcomes of 8671 chronic total occlusions (CTOs) percutaneous coronary interventions (PCIs) performed between 2012 and 2022 at 41 centers. Results: The prevalence of balloon uncrossable lesions was 9.2%. The mean patient age was 64.2 ± 10 years and 80% were men. Patients with balloon uncrossable lesions were older (67.3 ± 9 vs. 63.9 ± 10, p \u3c 0.001) and more likely to have prior coronary artery bypass graft surgery (40% vs. 25%, p \u3c 0.001) and diabetes mellitus (50% vs. 42%, p \u3c 0.001) compared with patients who had balloon crossable lesions. In-stent restenosis (23% vs. 16%. p \u3c 0.001), moderate/severe calcification (68% vs. 40%, p \u3c 0.001), and moderate/severe proximal vessel tortuosity (36% vs. 25%, p \u3c 0.001) were more common in balloon uncrossable lesions. Procedure time (132 (90, 197) vs. 109 (71, 160) min, p \u3c 0.001) was longer and the air kerma radiation dose (2.55 (1.41, 4.23) vs. 1.97 (1.10, 3.40) min, p \u3c 0.001) was higher in balloon uncrossable lesions, while these lesions displayed lower technical (91% vs. 99%, p \u3c 0.001) and procedural (88% vs. 96%, p \u3c 0.001) success rates and higher major adverse cardiac event (MACE) rates (3.14% vs. 1.49%, p \u3c 0.001). Several techniques were required for balloon uncrossable lesions. Conclusion: In a contemporary, multicenter registry, 9.2% of the successfully crossed CTOs were initially balloon uncrossable. Balloon uncrossable lesions exhibited lower technical and procedural success rates and a higher risk of complications compared with balloon crossable lesions

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Transitional Care for Patients with Congenital Colorectal Diseases: An EUPSA Network Office, ERNICA, and eUROGEN Joint Venture

Background: Transition of care (TOC; from childhood into adulthood) of patients with anorectal malformations (ARM) and Hirschsprung disease (HD) ensures continuation of care for these patients. The aim of this international study was to assess the current status of TOC and adult care (AC) programs for patients with ARM and HD. Methods: A survey was developed by members of EUPSA, ERN eUROGEN, and ERNICA, including patient representatives (ePAGs), comprising of four domains: general information, general questions about transition to adulthood, and disease-specific questions regarding TOC and AC programs. Recruitment of centres was done by the ERNs and EUPSA, using mailing lists and social media accounts. Only descriptive statistics were reported. Results: In total, 82 centres from 21 different countries entered the survey. Approximately half of them were ERN network members. Seventy-two centres (87.8%) had a self-reported area of expertise for both ARM and HD. Specific TOC programs were installed in 44% of the centres and AC programs in 31% of these centres. When comparing centres, wide variation was observed in the content of the programs. Conclusion: Despite the awareness of the importance of TOC and AC programs, these programs were installed in less than 50% of the participating centres. Various transition and AC programs were applied, with considerable heterogeneity in implementation, content and responsible caregivers involved. Sharing best practice examples and taking into account local and National Health Care Programs might lead to a better continuation of care in the future. Level of Evidence: III

Assessing managerial power theory: A meta-analytic approach to understanding the determinants of CEO compensation

Although studies about the determinants of CEO compensation are ubiquitous, the balance of evidence for one of the more controversial theoretical approaches, managerial power theory, remains inconclusive. The authors provide a meta-analysis of 219 U.S.-based studies, focusing on the relationships between indicators of managerial power and levels of CEO compensation and CEO pay-performance sensitivities. The results indicate that managerial power theory is well equipped for predicting core compensation variables such as total cash and total compensation but less so for predicting the sensitivity of pay to performance. In most situations where CEOs are expected to have power over the pay setting process, they receive significantly higher levels of total cash and total compensation. In contrast, where boards are expected to have more power, CEOs receive lower total cash and total compensation. In addition, powerful directors also appear to be able to establish tighter links between CEO compensation and firm performance and can accomplish this even in the face of powerful CEOs. The authors discuss the implications for theory and research regarding the determinants of executive compensation
