Abstract:
In home care, the use of oxygen therapy equipment is a determinant in the evolution of chronic patients who require its application. So far the education that users receive from professionals in charge of respiratory care regarding the use and its prescription in the home environment, generates good results compared to control and follow-up with patients; however, when due to clinical and physical conditions it is time to withdraw oxygen supplies from the home, there is little clarity in the criteria for suspension and withdrawal of these equipment, generating insecurity in patients and health professionals regarding the timely withdrawal of oxygen equipment at home, as well as generating unnecessary costs to institutions providing health services, it also promotes the shortage of oxygen cylinders in situations that are objectively needed.

Abstract:
It has long been documented that abnormal activities of distal cis-regulatory elements such as enhancers contribute to the intitation and progression of cancer. Recently, super-enhancer hijacking was found to be esstential for the activation of certain oncogenes. However, the mechanism of action for most tumor-specific super-enhancers still largely remain elusive. Here, we report that a potential oncogene ETS2 was activated by a super-enhancer located at its 3’ distal region in colorectal cancer (CRC). The super-enhancer physcially interacts with ETS2 promoter fragments and is required for transription activation of ETS2. Intriguingly, we found that a eQTL site for ETS2 resides in this super-enhancer and genetic variation at the SNP potentailly abolished the binding of a well-known oncogenic trancritpion factor MECOM. Consistently, the expression of MECOM and ETS2 correlated well with each other in CRC cell lines and multiple CRC datasets and silecning of MECOM induced downregulation of ETS2. Moreover, the expression of enhancer RNA (eRNA) from the ETS2 super-enhancer also correlated with the expression of ETS2 in primary CRC samples. Finally, silencing of both MECOM and ETS2 lead to the inhibition of proliferation, migration and sphere formation of CRC cells. Taken together, we uncovered a novel MECOM-super enhancer-ETS2 regulatory axis that might be crucial for activating oncogenic ETS2 in CRC.

Edward H. Abraham
Oklahoma Surgical Hospital, Tulsa Oklahoma
Keynote: Cystic fibrosis improves COVID-19 survival and provides clues for treatment of SARS-CoV
Biography:
Edward H. Abraham graduated from Harvard University with a college major in engineering, applied physics and chemistry. He was then accepted into the first class of the Harvard - MIT graduate program in Health Sciences and Technology and subsequently received his MD from Harvard Medical School. During his medical school training, he gained valuable research experience working in the laboratories of Professors Judah Folkman, Claude Lechene and Nobel Laureate Konrad Bloch. During his internship, residency and fellowship in pediatrics at Boston Children’s HospitalMedical Center, he worked directly with Professor Harry Shwachman and in the laboratory of Professor Jan Breslow focusing on cystic fibrosis (CF). He extended his CF studies with a subsequent post-doctoral research clinical investigator award from NIH. His work focused on membrane biochemistry in the laboratory of Professor Guido Guidotti at Harvard University. During these investigations, he discovered and investigated functions of ATP releasing pathways using biochemical and electrophysiological (patch-clamp) assays. He developed luciferase assays for precise measurement and imaging of extracellular ATP clouds. Dr. Abraham then completed a radiation oncology residency at Massachusetts General Hospital, Boston and subsequent Senior Investigator position with Dr. Paul Okunieff at the National Cancer Institute (NCI) where the role of extracellular ATP in cancer treatment was investigated. He subsequently assumed directorship of the Radiation Oncology Translational Research laboratory at Dartmouth Medical School in Hanover, NH. At Dartmouth he ran clinical trials testing the effects of ATP intravenous infusions on patients with stage IV cancers.
Abstract:
Systemic pools of ATP are elevated in individuals homozygous for cystic fibrosis (CF) as evidenced by elevated blood and plasma ATP levels. This elevated ATP level seems to provide benefit in the presence of advanced solid tumors (Abraham et al., Nature Medicine 2(5):593–596, 1996). We published in this journal a paper showing that IV ATP can elevate the depleted ATP pools of advanced cancer patients up to levels found in CF patients with subsequent clinical, biochemical, and quality of life (QOL) improvements (Rapaport et al., Purinergic Signalling 11(2): 251–262, 2015). We hypothesize that the elevated ATP levels seen in CF patients may be benefiting CF patients in another way: by improving their survival after contracting COVID-19. We discuss here the reasoning behind this hypothesis and suggest how these findings might be applied clinically in the general population

Keynote: Clinical Outcomes of Patients with Hepatic Insufficiency Undergoing Transcatheter Aortic Valve Implantation: A Systematic Review and Meta-analysis
Time : 13:30-14:00
Biography:
Zeyi Cheng is currently working as a cardiovascular surgeon at West China Hospital, Sichuan University, China. He has attended many international conference related to his field.
Abstract:
Objective: To investigate the effect of abnormal liver function on the outcome and safety after transcatheter aortic valve implantation (TAVI) and whether TAVI is superior to surgical aortic valve replacement (SAVR) in patients with hepatic insufficiency. Methods: We searched the databases of PubMed, Embase, the Cochrane Library, Web of Science up to 31 January 2021. Studies to be eligible if mortality after TAVI in patients with and without hepatic insufficiency, or mortality and complications for TAVI versus SAVR in patients with hepatic insufficiency were reported. This meta-analysis was registered with PROSPERO (CRD42021247495) and was carried out by using RevMan 5.3 and Stata 14.0. Results: This meta-analysis of 20 studies assessed a total of 220270 patients. Hepatic insufficiency was associated with higher short-term mortality [OR=1.88, 95%CI (1.38 to 2.58), P<0.00001] and 1-2 years mortality [OR=1.64, 95%CI (1.42 to 1.89), P<0.00001]. Between TAVI and SAVR in patients with hepatic insufficiency, there is statistically significant difference in in-hospital mortality [OR=0.46, 95%CI (0.27 to 0.81), P=0.007], the occurrence rate of blood transfusions [OR=0.34, 95%CI (0.24 to 0.48), P<0.00001) and the occurrence rate of acute kidney injury [OR=0.55, 95%CI (0.33 to 0.91), P=0.02]. Conclusions: TAVI patients with hepatic insufficiency may have negative impact both on short-term (inhospital or 30-day) and 1-2-years mortality. For patients with hepatic insufficiency, TAVI could be a better option than SAVR.

University of Chile, Chile
Keynote: Challenges for the empowerment of pregnant women in Primary Health Care in Chile
Biography:
Maribel Mella Guzman is a Magister in Bioethics and Assistant Professor at the University of Chile with more than 10 years of experience. She has dedicated herself to the study of the autonomy of women in particular in the period of pregnancy and of gender violence also in pregnant women.
Abstract:
Primary Health Care (PHC) is the fundamental pillar and gateway of the Chilean Health System. At this level, the midwife is in charge of people's Sexual and Reproductive Health. The purpose of this presentation is to present the role of midwives in PHC in terms of empowering gestational support and the challenges that this currently presents. Their role is essential in the accompaniment of women and their families since they are in charge of promoting a healthy pregnancy, prevention and maintenance of healthy lifestyles, early detection and timely referral of pathologies. The educational and empowering role of this professional stands out, placing her as a facilitating and empowering figure for women's autonomy; however, the challenges she faces are important: to overcome the hegemonic position of the health professional in order to remedy the state of submission in which pregnant women have been placed, to retake group education, which has shown better results in terms of empowerment, to incorporate the intersectional view in order to understand more deeply the differences and particularities of pregnant women, to incorporate an intercultural perspective that allows immigrant women and women belonging to indigenous peoples to feel represented and respected in the current health system and finally, to achieve a real communication and continuity of health care between the primary level (prenatal care) and the tertiary level (delivery care).

Abstract:
Chronic arsenic exposure and its cancer association is already known. Our study explored the epigenetic perspectives of arsenic toxicity. The major investigations we performed include DNA damage response, telomere regulation, arsenic methylation and mitochondrial biogenesis. Our novel findings are to identify signature patterns for arsenic exposure (compared to those who are unexposed) and arsenic-induced characteristic lesion (compared to arsenic exposed No Skin Lesion group). Although arsenic induced skin lesions are hallmarks of arsenic toxicity, it is observed only among15-20% of the exposed population. This clearly indicates environment and gene crosstalk each other with significant variation at population level. We have identified alteration in DNA methylation pattern for the candidate genes, histone post translational modifications and also differential miRNA regulation. Among all different pathways, most critical is the arsenic metabolism pathway. This metabolism depends on the efficiency of arsenic methylation, which is further dependant on methylation donor SAM (S-Adenosyl L-methionine) level and enzyme activity of AS3MT (Arsenite methyltransferase). Our study identified how arsenic depletes SAM level and affect overall metabolism leading to arsenic susceptibility. Mitochondrial biogenesis also play a significant role, where regulatory genes including PGC1α, Tfam, NRF1 and NRF2 were upregulated among arsenic induced cancer patients via promoter hypomethylation. Thus, our study considers a holistic approach to understand the epigenetic interplay in the individuals having prolonged arsenic exposure history.

Keynote: A Rare Case of Concomitant Acute Occlusion of Left Main Coronary Artery and Right Coronary Artery with characteristic Electrocardiographic pattern
Time : 15:00-15:30
Biography:
Thilina Jayesekara is currently working as a senior registrar in Cardiology at National Hospital Kandy, Sri Lanka. He has attended many international Conferences
Abstract:
Acute left main coronary artery (LMCA) occlusion is a rare clinical presentation which often manifests as a cardiogenic shock with worse prognosis. However, the clinical outcome depends on the age of the patient, co-morbidities, the patency and dominancy of Right coronary artery. Since LMCA supplies a large myocardial territory of left ventricle, it shows a characteristic electrocardiographic (ECG) pattern which helps to an early diagnosis. Presence of ST elevation in aVR with ST depressions of more than six leads is highly characteristic for LMCA occlusion. Here we are reporting an extremely rare case of acute concomitant occlusion of LMCA and Right coronary artery manifesting as a cardiogenic shock with ST elevation in aVR ,V1,III, aVF leads with ST depressions in all other leads. Patient showed excellent clinical outcome and reversal of characteristic ECG pattern following percutaneous coronary intervention (PCI) to the culprit vessels.

Abstract:
Background: Preterm incidence increased rapidly and its disproportionate contribution to increased infant mortality rates in Africa. Hence, the aim of this systematic review and meta-analysis was to determine the pooled mortality rate and associated contributing factors with decreasing the survival of preterm. Methods: PubMed, Google Scholar, Hinary, Cochrane library, research gate, and institutional repositories were retrieved were used to identity eligible articles through Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Data was extracted in the excel sheet considering mortality rate, and stratified the associated factors with mortality, then the data exported to STATA 14 for further analysis. I2 and Egger’s test were estimated to the heterogeneity and publication bias of the included article respectively. Subgroup analysis-based country, year, study design, year of publication, and sample size were also examined. Result: This meta-analysis included 32 articles with total of 21,405 study participants. The pooled mortality rate among preterm in Easter Africa found to be 19.2% (95%CI; 16.0–22.4). Regarding to study design, the mortality rate found to be 18.1%, 19.4%, and 19.7% with respect to prospective cohort, retrospective cohort, and cross-sectional studies. The pooled odds of mortality among preterm with respiratory distress syndrome decreased the survival by nearly three folds [AOR=3.2; 95% CI: 22, 4.6] when compared to those who didn’t have respiratory distress syndrome. Similarly, preterm presented with birth asphyxia nearly three times higher a risk death as compared with their counterparts [AOR=2.6; 95% CI: 1.9, 3.4]. Conclusion: Mortality of preterm was unacceptably high in Eastern Africa. Fortunately, the main causes of death were found to be respiratory distress syndrome and birth asphyxia, which are preventable and treatable hence early detection, and timely management of these risk factors is crucial to decrease preterm mortality significantly
