Hypertension is responsible for more than two million deaths due to cardiovascular disease annually in Latin America (LATAM), of which one million occurs before 70 years of age. Hypertension is the main risk factor for cardiovascular morbidity and mortality, affecting between 20 and 40% of LATAM adults. Since the publication of the 2017 LASH hypertension guidelines, reports from different LATAM countries have confirmed the burden of hypertension on cardiovascular disease events and mortality in the region.

Article Synopsis
  • The Knight-Alzheimer Disease Research Center at Washington University has been at the forefront of Alzheimer disease research for over 40 years, significantly enhancing our understanding through various studies on cognitive and molecular aspects.
  • Over 26,000 biological samples have been collected from participants, including DNA, RNA, plasma, and cerebrospinal fluid, to support extensive research on dementia and aging.
  • The Genetics and High Throughput -Omics core has conducted in-depth molecular profiling to discover new risk factors, biomarkers, and potential treatment targets for Alzheimer disease.

Atrial fibrillation (AF) is the most common arrhythmia in adults. Prevention of the ischaemic risk with oral anticoagulants (OACs) is widely recommended, and current clinical guidelines recommend direct oral anticoagulants (DOACs) as preference therapy for stroke prevention. However, there are currently no clinical practice guidelines or recommendation documents on the optimal management of OACs in patients with AF that specifically address and adapt to the Central American and Caribbean context.

tendon and ligament research can be limited by the difficultly of obtaining tissue samples that can be biochemically analyzed. In this study, we characterize the most widely used engineered ligament model. Despite previous works suggesting multiple passages change gene expression in 2D primary tenocytes, we found no relationship between passage number and expression of classical tendon fibroblast markers across different biological donors.

Latin American hypertension guidelines, tailored to the needs of countries of Central and South America, should be applied and known by most Latin American physicians. The knowledge and implementation of the Guidelines is one of the greatest challenges of hypertension societies in Latin America such as the Central American and Caribbean Society of Arterial Hypertension (SCCH), the Latin American Society of Hypertension (LASH) and the Inter-American Society of Cardiology (SIAC). In 2020, the Inter-American Society of Cardiology (SIAC) published its position on the current Guidelines for Arterial Hypertension due to the need to standardize the evaluation, diagnosis, treatment and control of hypertension, establishing recommendations that should be adopted in all Latin American countries, aimed at optimizing the management of cardiovascular risk and achieving a substantial improvement in the reduction of cardiovascular events and mortality.
