RESUMEN
BACKGROUND: The National Persian Registry of Cardiovascular Disease (N-PROVE) has been established to provide a comprehensive database of cardiovascular diseases in the Iranian community for further investigations and to develop national guidelines for the diagnosis, treatment, and prevention of cardiovascular disease (CVD). As with most clinical registries, a quality control audit is necessary to ensure a comprehensive and accurate registry; the current study aims to assess the validity and quality of the N-PROVE/Angiography/Percutaneous Coronary Intervention (PCI) registry. METHODS: The current cross-sectional quality assessment study serves as an example of data quality assessment in N-PROVE on a sample of patients registered in the N-PROVE/Angiography/PCI registry since 2020. Accordingly, data of 194 patients, including comorbidities, angiography, and angioplasty characteristics, were collected from the N-PROVE/Angiography/PCI registry as the main database and reevaluated by a panel consisting of a cardiologist and two coronary intervention fellowships as a test database. RESULTS: The quality control of the population-based healthcare database, the N-PROVE/PCI, revealed that the average error rate in terms of comorbidities, angiography characteristics, angioplasty characteristics, and in total were 3.8%, 2.3%, 3%, and 3.03%, respectively. CONCLUSION: According to the findings of this study, the N-PROVE/PCI registry had an average error of less than 4% in the assessed dimensions, including comorbidities, angiography, and angioplasty characteristics. Therefore, this registry appears valid and may be used for contemporary epidemiological studies.
RESUMEN
Circular RNAs (circRNAs) as small non-coding RNAs with cell, tissue, or organ-specific expression accomplish a broad array of functions in physiological and pathological processes such as cancer development. Angiogenesis, a complicated multistep process driving a formation of new blood vessels, speeds up tumor progression by supplying nutrients as well as energy. Abnormal expression of circRNAs reported to affect tumor development through impressing angiogenesis. Such impacts are introduced as constant with different tumorigenic features known as "hallmarks of cancer". In addition, deregulated circRNAs show possibilities to prognosis and diagnosis both in the prophecy of prognosis in malignancies and also their prejudice from healthy individuals. In the present review article, we have evaluated the angiogenic impacts and anti-angiogenic managements of circRNAs in human cancers.

Endothelial dysfunction is identified by a conversion of the endothelium toward decreased vasodilation and prothrombic features and is known as a primary pathogenic incident in cardiovascular diseases. An insight based on particular and promising biomarkers of endothelial dysfunction may possess vital clinical significances. Currently, non-coding RNAs due to their participation in critical cardiovascular processes like initiation and progression have gained much attention as possible diagnostic as well as prognostic biomarkers in cardiovascular diseases. Emerging line of proof has demonstrated that abnormal expression of non-coding RNAs is nearly correlated with the pathogenesis of cardiovascular diseases. In the present review, we focus on the expression and functional effects of various kinds of non-coding RNAs in cardiovascular diseases and negotiate their possible clinical implications as diagnostic or prognostic biomarkers and curative targets.

Background: Determining cardiovascular disease (CVD) research priorities is essential given the high burden of these diseases, limited financial resources, and competing priorities. This study aimed to determine the research priorities in CVD field in Iran using standard indigenous methods. Materials and Methods: An extensive search was done in relevant international and national studies. Then, an indigenous standard multistage approach based on multicriteria decision analysis steps was adapted to local situation and implemented. This process included forming a working group of experts in priority setting methodology, identifying the context and prioritization framework, discussing the methodology with the National Network of CVD Research (NCVDR) members who ultimately determined the priority research topics, weighted topics criteria, ranked topics, and reviewed all determined research priorities for final report. Results: Thirteen cardiovascular research priorities were determined by the NCVDR members. The first five priorities based on their scores include studies in hypertension, prevention and control of ischemic heart disease (IHD) and its risk factors, burden of IHD, Registration of CVDs, and COVID-19 and CVDs. Conclusion: Cardiovascular research priorities were determined using a standard indigenous approach by national experts who are the NCVDR members. These priorities can be used by researchers and health decision makers.
RESUMEN
BACKGROUND: With the onset of the coronavirus disease-2019 (COVID-19) pandemic, hospitalization and treatment of non-covid patients decreased worldwide. The aim of this study is to evaluate the admission and treatment of patients with coronary artery diseases (CADs) by examining coronary Cath labs activities in some centers of Iran during the COVID-19 period. METHODS: A retrospective, multi-center survey was conducted in four cites in Iran which participated in National Persian Registry Of CardioVascular diseasE (N-PROVE). Two periods of COVID-19 occurrence peak in Iran were compared with the same date in 2019. Information was collected on the number of diagnostic and therapeutic coronary catheterizations in both stable ischemic heart diseases (SIHDs) and acute coronary syndrome (ACS) settings. RESULTS: In the first peak of COVID-19 pandemic, coronary angiographies and angioplasties decreased by 37 and 38% compared to the same period in 2019, respectively. The most common indication for coronary angiography during this period was ACS [especially ST-Segment Elevation Myocardial Infarction (STEMI)]; however, at the time of peak decrease, the SIHDs were the most. In the second peak of COVID-19 pandemic in Iran, 34% and 27% decrease in diagnostic and therapeutic coronary procedures were seen, respectively. During this period, the number of elective admissions increased, although it was still lower than that in 2019. The tendency to rescue percutaneous coronary intervention increased in most centers during the COVID-19 era, especially in the second peak. CONCLUSION: A significant reduction in the coronary Cath lab activity has been observed during the COVID-19 pandemic that can indicate an increased risk of cardiovascular mortality and morbidity.
RESUMEN
OBJECTIVE: Carvedilol is a nonselective third generation ß-blocker that does not display the negative effects of traditional ß-blockers. Regarding the antioxidant, anti-inflammatory and distinct metabolic properties of carvedilol which are similar to that of high-density lipoprotein (HDL) and paraoxonase 1 (PON1), the present study intends to investigate the effects of carvedilol treatment on malondialdehyde (MDA) and soluble lectin-like ox-low-density lipoprotein (LDL) receptor (sLOX-1) as markers of oxidative stress in association to lipid profiles, apolipoproteins (apo), and PON1 activity in hypertensive patients. PATIENTS AND METHODS: This clinical trial study was performed on forty patients with mild to moderate essential hypertension. Subjects were studied before and after 2 months treatment with carvedilol, 25 mg daily. Lipids and lipoproteins were measured using a biochemistry analyzer. PON and arylesterase activity were assayed using paraoxon and phenyl acetate as substrates, respectively. MDA was quantified using a chemical colorimetric assay. ELISA was used to measure sLOX-1. RESULTS: Our results showed that carvedilol treatment decreased systolic and diastolic blood pressure as much as forty and 16 mmHg, respectively (P < 0.001). It also increased HDL, total cholesterol, and serum PON1 activity (P < 0.05), but the levels of triglyceride, LDL, apo A-I, and apo B did not significantly change. There was an inverse correlation between serum PON1 activity and serum MDA. CONCLUSION: This study confirmed the antihypertensive effect of the drug and its beneficial metabolic effects through augmenting HDL and PON1 activity. We propose that the antioxidant effects of carvedilol can be partially attributed to increased PON-1 activity.
