Keynote: Novel strategies to encounter inflammation and ER stress in coronary artery disease
Biography:
Abstract:
Atherosclerosis is the underlying cause of coronary artery disease (CAD) and a disease of multifactorial etiology. Recent investigations in atherosclerosis have been focused on inflammation and endoplasmic reticulum (ER) stress, providing new insights into the mechanism of the disease. Keeping in view the multifactorial aspects of this disease, novel strategies are urgently needed not only for identification of novel biomarkers, but also to search for remedies for prevention and treatment of this disease. C-reactive protein (CRP) is reported to be a biomarker of inflammation in CAD and is shown to actively contribute to the disease pathology. Our data from in vitro studies provided substantial evidence that MMP-TIMP and RAGE-EN-RAGE interactions significantly contribute to the pathophysiology of coronary artery disease. CRP was found to play a potential role in the induction, amplification, and prolongation of inflammatory response in atherosclerosis via modulating these genes and atorvastatin showed the potential to curb the deleterious effects of CRP. However, it is evident that besides use of several drugs like statins, inflammation persists in CAD patients. Therefore, we conducted studies with Terminalia arjuna (TA), a medicinal plant with a wide variety of applications in traditional medicine and referred to as a cardiotonic in Ayurvedic system of medicine. Evidence in literature demonstrates that TA like atorvastatin possesses pleotropic properties. Studies carried out in our laboratory have clearly demonstrated its anti-inflammatory and antithrombotic properties both in vitro as well as in vivo and in experimental animals. Expression of inflammatory genes eg. was found to be significantly reduced in vitro in a dose and time-dependent manner by Terminalia arjuna. Using a Systems Biology approach, observations of the in vitro study were further validated in a randomized, placebo-controlled, double-blind clinical trial in subjects with stable CAD who received either placebo or T. arjuna (500 mg twice a day; Himalaya) and were followed up to 6 months. TA was shown to attenuate inflammation and played a pivotal role in modulation of both cellular and humoral immunity. Chronic ER stress is implicated in the pathophysiology of atherosclerosis and is found to be associated with apoptosis. Research work in our lab demonstrated that TA specifically targeted early foam cell apoptosis via activation of unfolded protein response pathway. The data from our studies suggests use of a multipronged approach using novel therapies in terms of combination/ adjuvant therapy in clinical studies utilizing indigenous resources of medicinal plants to prevent/treat complex disorders such as CAD.

Keynote: Clinical decision-making styles and critical thinking skills among general care nurses in Malaysia
Biography:
Khatijah Lim Abdullah has completed her Doctorate from the University of Southampton UK. She is currently a Professor in Nursing in University of Malaya, Malaysia and Vice President for Qualitative Research Association Malaysia. She has published more than 50 papers in reputed journals and is presently the Chief Editor for Malaysian Journal of Qualitative Research.
Abstract:
The aim of this study is to assess the relationships between critical thinking skills and types of clinical decision-making among general care nurses in Malaysia. This quantitative descriptive correlational study was conducted in nine public hospitals from Peninsular Malaysia. Five hundred and forty nine nurses recruited via multistage cluster sampling, completed the demographic data questionnaire, Health science reasoning test (HSRT) and 24-item Nursing Decision-making instrument (24-NDM). The results of the study show that nurses’ average HSRT score was 13.8±3.4 which meant the majority of them failed to manifest critical thinking skills. In addition, the results show that 65.2% of the nurses studied were more inclined in making quasi-rational decisions, with 24.6% inclined towards analytical-systematic decisions, whereas only 10.2% displayed intuitive-interpretive decisions (=268, df=2, p<0.001). With multinomial logistic regression, only education qualification is significantly associated with the nurses’ critical thinking score, whereas years of working experience and education qualification significantly predicted types of clinical decision nurses made (p<0.001). Finally, there is significant positive relationship between critical thinking skills and clinical decision-making, which accentuates the positive results yielded from previous studies. This finding provides further evidence that critical thinking and clinical decision-making are both interrelated. Since clinical decision-making cannot be easily taught in nursing curricula, cultivating critical thinking among nursing students perhaps is the right remedy for producing future nurses who can make effective clinical decisions.

Abstract:
Introduction: One of important issues in pediatric cardiac surgery is myocardial protection. When cardioplegic solution is injected into coronary arteries with a pump to ensure myocardial protection, it is necessary to determine the correct delivery pressure to avoid damage of the heart.
Methods: We investigated 12 coronary artery specimens without cardiac pathology retrieved from autopsies of neonates 9.3±9.7 days old and weight 3.99±0.7 kg and compared them to seven adult specimens with no detected atherosclerosis. Specimens were pressurized from 0 to 200 mmHg with the step of 20 mmHg, while maintaining the length of the sample in situ. Structural damages were investigated afterwards with light microscopy and immunohistochemistry.
Results: There was a rapid increase of strain until the inner pressure reached 80-100 mmHg, whilst the increase of stress in the wall of neonatal coronary arteries was less rapid. When the internal pressure exceeds 100 mmHg, the strain of the arterial wall increases much slower, but the wall stress and modulus of elasticity begin to increase rapidly - the structural elements of the arterial wall have been straightened and possible damage may appear. Results were compared with biomechanical properties of arterial wall of adults and differences had been found. Morphologic examination of tensile properties revealed prominent affection of the vascular wall of neonates with accentuated redistribution (loosening) of medial myocytes and adventitial vasa vasorum after being pressurized with the inner pressure of over than 100 mmHg.
Conclusions: Our experimental results show that the delivery pressure of the cardioplegic solution in neonatal coronary arteries should not exceed 100 mmHg. A raised inner pressure may increase the risk of structural damage of the vascular wall leading to the injury of myocardium.

Title: Defective cilia in endocardial derived cells; A cause for congenital heart defects?
Biography:
Cindy Rodrigues Cleto is a sixth year Medical Student at the University of Liverpool, UK. She completed an MReS in Cardiovascular Science at the University of Newcastle where she carried out this research.
Abstract:
Introduction: Primary cilia on endocardial cells could prove to be a cause of congenital heart defects. Endocardial cells mainly contribute to the outflow tract (OFT) and atrioventricular (AV) endocardial cushion; later developing into the four heart valves. Knocking out IFT88 creates abnormal primary cilia and in turn causes cardiac malformations.
Aims: The aims of this study were to establish the spatiotemporal expression of primary cilia on endocardial derived cells; and by using an IFT88 mouse model, to discover if defecting to the primary cilia in endocardial derived cells causes an abnormal cardiac phenotype?
Methods: For the spatiotemporal expression of primary cilia, Tie2Cre positive mouse embryos of age’s e10.5-e12.5 were stained with anti-green fluorescent protein and acetylated tubulin to show the endothelial cells and primary cilia respectively. For the IFT88 mouse model, three mutants were collects at e15.5; two were hematoxylin and eosin stained to look at histology and one was stained with acetylated tubulin to show any defect in the primary cilia.
Results: The spatiotemporal expression of primary cilia mainly highlighted that there is an abundance of cilia in the OFT and AV endocardial cushions at e10.5 and e11.5 but this significantly drops by e12.5. The IFT88 mouse model showed that knocking out IFT88 significantly decreases the number of primary cilia in mutants, causing cardiac malformations including atrio-ventricular septal defects and dysplastic mitral and tricuspid valves.
Conclusion: Primary cilia are present in the endocardial derived cells at earlier time points. Knocking out IFT88 does produce defective cilia that lead to cardiac malformations.

Title: Aberrant DNA methylation of M1-macrophage genes in coronary artery disease
Biography:

Abstract:
Macrophage heterogeneity within atherosclerotic lesions has attracted much interest owing to the importance of balance between M1 and M2 population. Though, it remains unknown how macrophage heterogeneity is regulated. Moreover, the regulation of macrophage polarization and activation also involve DNA methylation. However, it remains unknown which genes are directly regulated by DNA methylation. The aim of the study was to assess the gene-specific promoter DNA methylation status of M1/M2 macrophage polarization markers STAT1, STAT6, MHC2, IL12b, iNOS, JAK1, JAK2 and SOCS5 in peripheral blood mononuclear cells of CAD patients. A case-control study was performed with 25 CAD patients and 25 controls to investigate the gene-specific promoter DNA methylation status using MS-HRM analysis. Our data indicates that there was a clear-cut difference in the pattern of gene-specific promoter DNA methylation of above mentioned genes in CAD patients as compared to controls. A consistent hypomethylated pattern was observed for most of the samples including both CAD patients and controls, which was heterogeneous DNA methylation as evident by their melting profiles. A significant difference was observed between the mean percentage methylation of STAT1, IL12b, MHC2, iNOS, JAK1 and JAK2 in CAD patients and control subjects. Our data showed that MS-HRM assay is a rapid and inexpensive method for qualitatively investigation and identification of aberrant gene-specific promoter DNA methylation changes in CAD. Since, monocytes and macrophages play a significant role in atherosclerosis, we propose that epigenetic markers including gene-specific promoter DNA methylation based on monocyte/macrophage might aid as diagnostic markers or drug targets for clinical application. Therefore, skewing the M1/M2 balance towards a more preferable phenotype through DNA methylation-related interventions may offer novel possibilities for atherosclerotic disease management.

Title: S-Nitrosylation of transglutaminase 2 impairs fatty acid-stimulated contraction in hypertensive cardiomyocytes
Biography:
Abstract:
Transglutaminase 2 (TG2) is a calcium-dependent enzyme and in the cardiovascularsystem, TG2 has been reported to be involved in the development of cardiac hypertrophy, vessel remodeling, and age related vascular stiffness. Interestingly, TG2 is implicated in the regulation of muscle metabolism via modification of respiratory complexes and the ADP/ATP transporter in the mitochondria of myocardium. However, the role of TG2 in the heart during conditions of pressure overload in relation to fatty acid(FA) oxidation has not been investigated. Hence, we investigated the involvement of TG2 in cardiomyocytes contraction under FA supplementation. Using TG2 inhibitor and TG2-deficient mice, we demonstrated that FA-supplementation activated TG2 and increased ATP level and contractility of cardiac myocyte from normal heart. By contrast, in cardiac myocytes from angiotensin-II treated rats and mice, the effects of FA-supplementation on TG2 activity, ATP level and myocyte contraction were abolished. Furthermore, TG2 was inhibited by S-nitrosylation and its level increased in hypertensive myocytes. Treatment with inhibitor for neuronal nitric oxide synthase (nNOS) restored FA-induced increase of TG2 activity and myocyte contraction. Moreover, intracellular Ca2+ levels were increased by FA-supplementation in both normal and hypertensive myocytes, showing that S-nitrosylation of TG2 but not alteration of intracellular Ca2+ levels are responsible for contractile dysfunction. These results indicate that TG2 plays a critical role in the regulation of myocyte contractility by promoting FA metabolism and provide a novel target for preventing contractile dysfunction in heart with high work-load.

Abstract:
Abstract
Background & Objective: Non-nutritive sucking (NNS) using a finger or pacifier is a natural reflex for infants. In gratifying this innate need, NNS can be soothing and may facilitate a smooth transition to sleep. We hypothesized that infants with their innate desire for gratification through NNS may overfeed if the bottle or breast is constantly offered instead of a pacifier. Our primary objective was to determine whether the use of pacifier in early infancy is associated with lower incidence of obesity at 9-15 month of age.
Methods: Parents of 399 infants 9 to 15 months old visiting the General Academic Pediatric Clinic were interviewed. They were asked whether a pacifier was used consistently ≥9 months and the reason for its use. BMIs at birth, 6 months and on the day of interview were calculated.
Results: Of the 399 recruited infants, 204 (51%) used a pacifier consistently for ≥9 months and 195 (49%) were non-user. More infants in the pacifier non-user group were significantly either overweight, 40 (21%) with BMI ≥85% or obese, 32 (16%) with BMI ≥95% than in the pacifier user group: 22 (11%) and 22 (11%) respectively (P.003). Formula fed infants accounted for the increased number of overweight and obese infants in the non-user group.
Conclusions: The use of a pacifier in infancy was associated with a lower incidence of obesity at 9-15 month of age. Given the current prevalence of childhood obesity, we believe that offering a pacifier between feeds can provide a protective effect against infantile obesity.

Abstract:
While the health-related quality of life (HRQOL) of children with congenital heart defects is primarily affected, caring for a child with birth defect has an impact on the family’s quality of life as well. Understanding the level of quality of life of the parents, which is likely to vary in different cultural settings, beliefs and parental educational status may help to implement educational programs and other interventional measures that may improve the HRQOL of parents of such children. This cross-sectional comparative study reports the health-related quality of life of mothers of children with congenital heart diseases in a sub-Saharan setting. Mean age of the mothers in the study group was 32.2±7.1 years where as that of the control group was 30.5±6.5 years (p=.054). One hundred-four children had congenital cardiac lesions classified as mild to moderate while 31 patients had severe lesions. On average, mothers in the study group showed poor performance on the Short Form-36 (SF-36) survey with statistically significant differences on all sub-scales including general health perception, physical functioning, role physical, role emotional, social functioning, bodily pain, vitality and mental health. Severity of the congenital heart defect was not associated with statistically significant difference in the health-related quality of life of the mothers. Mothers of children with congenital heart disease in our study have significantly lower quality of life in all domains of SF-36 compared to the control group. Planning and devising a strategy to support these mothers may need to be part of management and clinical care of children with congenital heart diseases.

Title: Utilization of pain simulation in nursing education
Biography:
Angela Harrinanan is a nursing professor at Centennial College with extensive pain management experience in acute pain service. She also works at Centennial Health Simulation center as a simulation support for faculty with limited simulation experience. Angela holds a Master in Nursing from University of Toronto, specializing in Nurse Practitioner.
Abstract:
Introduction: Pain management has been identified as one critical element in nursing practice and students are required to assess and manage pain appropriately. Many studies support the effectiveness of simulation as a teaching methodology; however there is a gap in measuring students’ learning outcomes in pain simulation. The purpose of this study is to assess students’ knowledge of pain assessment and management. Furthermore this research study is to explore students’ perspectives in pain simulation.
Research Question/Hypothesis: Will the pain simulation experience improve students’ knowledge of pain (a) assessment and (b) management? (c) What is the students’ perspective/experience when participating with the pain simulation?
Methods: A mixed methods approach was utilized to gain an understanding of student’s learning of pain assessment and management in simulation. A convenience sample of 159 year two BSc Nursing students were recruited for Adapted Pain Knowledge and Attitude Pre- and Post-Simulation Surveys during their scheduled simulation experience in winter 2018 semester. Additionally, 10 students participated in focus group sessions to explore nursing students’ experience in pain simulation.
Results: Descriptive and qualitative data were analyzed with five themes emerging: Developing appropriate pain assessment skills, administrating pain medication with clinical reasoning, enlightening pain management from patient’s perspective, developing clinical decision making and providing new perspective of pain management. Themes were derived from qualitative focus group findings and aligned with the pre- and post-pain knowledge and attitude survey (PPKAS) quantitative results (McCaffery and Ferrel, 2012). Key learning points that student have gained from pain simulation experience are: Communicating effectively with patient, do not underestimate patient’s pain, acquiring “solid” pain medication knowledge to provide safe patient care, “Practice makes perfect” and tailoring pain medication based on patient’s conditions.
Conclusion: The PPKAS surveys and focus group discussions reveal student’s learning perspectives and suggestions for future pain simulation to; supporting student learning in pain simulation; fostering student centered learning simulation environment and; providing faculty support in pain simulation.

Abstract:
Introduction: The hospitalization of post cardiac surgery ICU patients constitutes a complex mixture of procedures affected by a variety of clinical, administrational and technical aspects of care. The respective cost may drastically increase due to these patients’ increased clinical needs, including also the clinical state of delirium which is a quite common complication following this type of operation.
Methods: Τhe study included 179 consecutive patients who underwent open heart operation with cardiopulmonary bypass. The Confusion Assessment Method (CAM-ICU) was used for delirium diagnosis. Hospitalization outcomes were recorded by measuring certain intra - and post - operative procedure time intervals, along with the ICU and in-hospital length of stay as well.
Results:
A total of 179 patients post cardiac surgery were investigated, 129 of them were male and the rest 50 were female. The delirium complication was recorded in 20 out of 179 patients of the study (11.2%)
Bivariate analysis revealed that prolonged intraoperative time in cardiopulmonary bypass (p<0,001), prolonged sedation time (p=0,005) and prolonged length of stay with endotracheal tube (p<0,001) were significantly correlated with increased total health care cost.
Multivariate analysis showed that the level of complexity of the surgical operation (p<0,001), delirium complications (p<0,001) and the prolonged in-hospital length of stay (p<0,001), formulated altogether a group of factors for total health care cost increase.
Conclusions: A variety of factors seem to increase post cardiac surgery ICU patients’ total hospitalization cost and jeopardize quality of care and health outcomes. Resource management and monitoring, analytical process of health care costing in the Cardiac ICU and Ward, and recruitment of nursing staff with advanced
