BIBR1532 inhibits proliferation and metastasis of esophageal squamous cancer cells by inducing telomere dysregulation.

Background: Esophageal squamous cell carcinoma (ESCC) is a malignant tumor with high morbidity and mortality, and easy to develop resistance to chemotherapeutic agents. Telomeres are DNA-protein complexes located at the termini of chromosomes in eukaryotic cells, which are unreplaceable in maintaining the stability and integrity of genome. Telomerase, an RNA-dependent DNA polymerase, play vital role in telomere length maintain, targeting telomerase is a promising therapeutic strategy for cancer.

Valvular Heart Disease Care in Pakistan: Impact of the Multidisciplinary Valve Heart Team.

Background: Patients with complex valvular heart disease (VHD) should be evaluated by a multidisciplinary heart team (HT). In low- and middle-income countries, referral practices are more variable, permitting any physician to refer patients directly to a cardiac surgeon without prior formal evaluation by a cardiologist with expertise in VHD.

Objectives: The goal of the study was to examine the demographics of VHD patients seen in a large heart valve center in a low- and middle-income country and to assess the impact of the multidisciplinary HT in patients referred for valve surgery.

Background: Despite implementation of preventive interventions targeting cardiovascular disease (CVD), atherosclerotic CVD (ASCVD) remains a major public health concern in the South Asian (SA) population.

Objectives: The purpose of this study was to assess the risk factor prevalence and ASCVD outcomes in SA population in the United States.

Methods: The DIL Wellness and Arterial health Longitudinal Evaluation registry collected data retrospectively on SA adult patients receiving care in the Baylor Scott & White Healthcare system.

30-Day and 1-Year Acute Myocardial Infarction Outcomes in Côte d'Ivoire: The REACTIV Study.

Methods: This prospective cohort study used data from the REgistre des syndromes coronariens Aigus de CôTe d'IVoire (REACTIV).

Prospective Pakistan Registry of Echocardiographic Screening in Asymptomatic Pregnant Women.

Background: Cardiovascular diseases are the primary cause of nonobstetric morbidity and mortality in pregnant women worldwide. Pakistan's high maternal and neonatal mortality rates underscore the need for effective screening protocols to detect cardiovascular diseases during pregnancy.

Objectives: The objective of this study was to assess the prevalence and factors associated with structural heart disease among pregnant women without active cardiorespiratory symptoms (no symptoms or symptoms attributed to pregnancy) attending routine antenatal appointments.

Sub-Saharan Africa's Contribution to Clinical Trials in International Acute Coronary Syndromes and Heart Failure Guidelines.

Background: There is a growing burden of acute coronary syndrome (ACS) and heart failure (HF) in sub-Saharan Africa (SSA), yet outcomes remain poor compared to high-income countries. The European Society of Cardiology (ESC) international guidelines are pivotal to the delivery of evidence-based care; however, their representation of populations from SSA remains unclear.

Objectives: The purpose of the study was to evaluate the representation of populations from SSA in randomized controlled trials (RCTs) that inform ESC ACS and HF guidelines.

Valvular Heart Disease-Related Mortality Between Middle- and High-Income Countries During 2000 to 2019.

Background: Valvular heart disease (VHD) management has evolved rapidly in recent decades, but disparities in health care access persist among countries with varying socioeconomic backgrounds.

Objectives: The purpose of this study was to investigate global mortality trends from VHD and assess the difference between middle- and high-income countries.

Methods: We obtained mortality data from the World Health Organization Mortality Database for VHD and its subgroups (rheumatic valvular disease [RVD], infective endocarditis [IE], aortic stenosis [AS], and mitral regurgitation [MR]) from 2000 to 2019.

Ethnic Differences in Atrial Fibrillation in the United Kingdom.

Background: Within the United States, White individuals experience a higher risk of atrial fibrillation (AF) while exhibiting a lower AF-related stroke risk compared to other ethnic groups. It is possible that these observations stem from phenomena unique to the United States, such as differential health care access. The United Kingdom provides socialized medicine, which ostensibly promotes equitable health care access.

The Impact of Air Pollution on Cardiovascular Health Outcomes in African Populations: A Scoping Review.

Background: Air pollution is a significant environmental risk factor for cardiovascular diseases (CVDs), but its impact on African populations is under-researched due to limited air quality data and health studies.

Objectives: The purpose of this study was to synthesize available research on the effects of air pollution on CVDs outcomes in African populations, identify knowledge gaps, and suggest areas for research and policy intervention.

Methods: A systematic search of PubMed was conducted using terms capturing criteria ambient air pollutants (for example particulate matter, nitrogen dioxide, ozone, and sulfur dioxide) and CVDs and countries in Africa.

Electrical Heterogeneity in Hispanic Background Subpopulations: The HCHS/SOL.

Background: The Hispanic/Latino population is not uniform. Prevalence and clinical outcomes of cardiac arrhythmias in ethnic background subgroups are variable, but the reasons for differences are unclear. Vectorcardiographic Global Electrical Heterogeneity (GEH) has been shown to be associated with adverse cardiovascular outcomes.

Global Disparities in Outcomes of Pregnant Individuals With Rheumatic Heart Disease: A Scoping Review.

Background: Rheumatic heart disease (RHD) remains as 1 of the major contributors to indirect pregnancy-related mortality and morbidity worldwide and disproportionately affects marginalized populations.

Objectives: In this scoping review, the authors sought to explore the socioeconomic, cultural, and health care access-related causes of global disparities in outcomes of pregnancy among individuals with RHD.

Methods: We performed a literature search of all studies published between January 1, 1990, and January 1, 2022, that investigated causes for disparate outcomes in pregnant individuals with RHD.

Rheumatic Heart Disease Burden in Africa and the Need to Build Robust Infrastructure.

Rheumatic heart disease (RHD) is an important public health problem in Africa. Mapping the epidemiology of RHD involves elucidating its geographic distribution, temporal trends, and demographic characteristics. The prevalence of RHD in Africa varies widely, with estimates ranging from 2.

A Scoping Review of Electronic Health Records-Based Screening Algorithms for Familial Hypercholesterolemia.

Background: Familial hypercholesterolemia (FH) is a common genetic disorder that is strongly associated with premature cardiovascular disease. Effective diagnosis and appropriate treatment of FH can reduce cardiovascular disease risk; however, FH is underdiagnosed. Electronic health record (EHR)-based FH screening tools have been previously described to enhance the detection of FH.

Sex Disparities in Ischemic Heart Disease Mortality in Europe.

Background: Ischemic heart disease (IHD) is the leading cause of death in the European Union (EU). Understanding variations by sex, income, and countries can help in tailoring effective public health policies.

Objectives: The purpose of the study was to examine trends in sex differences in IHD prevalence and prognosis within the EU.

Etiology and Phenotypes of Cardiomyopathy in Southern Africa: The IMHOTEP Multicenter Pilot Study.

Background: Cardiomyopathies are an important cause of heart failure in Africa yet there are limited data on etiology and clinical phenotypes.

Objectives: The IMHOTEP (African Cardiomyopathy and Myocarditis Registry Program) was designed to systematically collect data on individuals diagnosed with cardiomyopathy living in Africa.

Methods: In this multicenter pilot study, patients (age ≥13 years) were eligible for inclusion if they had a diagnosis of cardiomyopathy or myocarditis.

PREVENT and Pooled Cohort Equations in Mortality Risk Prediction: National Health and Nutrition Examination Survey.

Background: The Predicting Risk of CVD Events (PREVENT) equations were developed to address limitations of the Pooled Cohort Equations (PCEs) in predicting atherosclerotic cardiovascular disease (ASCVD) risk. The comparative effectiveness of the PREVENT equations versus the PCEs in predicting mortality risk remains unknown.

Objectives: The purpose of this study was to compare the risk discrimination value of the PREVENT equations with the PCEs for predicting mortality.
