The Caribbean Research for Action Agenda emerged from collaboration between nongovernmental organizations, academic institutions, and multilateral agencies that organized a conference on climate change and health in the Caribbean. This Agenda was formulated by prioritizing research areas, synthesizing evidence from conference presentations and scientific literature, and holding consultations with stakeholders and experts.

Work-Related Stress Is Associated With Unfavorable Cardiovascular Health: The Multi-Ethnic Study of Atherosclerosis.

Background: Work-related stress is a psychosocial risk factor linked to a higher risk of cardiovascular disease. However, the association between work-related stress and cardiovascular health (CVH) is not well established. We estimated the association between work-related stress and CVH in a multiethnic sample of adults free of cardiovascular disease at baseline.

PPARγ/ETV2 axis regulates endothelial-to-mesenchymal transition in pulmonary hypertension.

Endothelial-to-mesenchymal transition (EndoMT) plays an important role in pulmonary hypertension (PH) but the molecular mechanisms regulating EndoMT remain to be defined. We demonstrate that the axis of the transcription factors PPARγ (Peroxisome Proliferator-Activated Receptor gamma) and ETV2 (ETS variant 2) play important roles in the pathogenesis of PH. Decreased levels of the expression of PPARγ and ETV2 along with reduced endothelial and increased EndoMT markers are consistently observed in lungs and pulmonary artery endothelial cells (PAECs) of idiopathic pulmonary arterial hypertension patients, in hypoxia-exposed mouse lungs, human PAECs, and in induced-EndoMT cells.

Building Digital Twins for Cardiovascular Health: From Principles to Clinical Impact.

The past several decades have seen rapid advances in diagnosis and treatment of cardiovascular diseases and stroke, enabled by technological breakthroughs in imaging, genomics, and physiological monitoring, coupled with therapeutic interventions. We now face the challenge of how to (1) rapidly process large, complex multimodal and multiscale medical measurements; (2) map all available data streams to the trajectories of disease states over the patient's lifetime; and (3) apply this information for optimal clinical interventions and outcomes. Here we review new advances that may address these challenges using digital twin technology to fulfill the promise of personalized cardiovascular medical practice.

Alzheimer's disease cerebrospinal fluid biomarkers and kidney function in normal and cognitively impaired older adults.

Introduction: Recent Alzheimer's disease (AD) clinical trials have used cerebrospinal fluid (CSF) biomarker levels for screening and enrollment. Preliminary evidence suggests that AD risk is related to impaired renal function. The impact of kidney function on commonly used AD biomarkers remains unknown.

Purpose Of Review: Asthma exacerbations are associated with substantial symptom burden and healthcare costs. Viral infections are the most common identified cause of asthma exacerbations. The epidemiology of viral respiratory infections has undergone a significant evolution during the COVID-19 pandemic.

Discovery of phytochelatins in human urine: Evidence for function in selenium disposition and protection against cadmium.

This report identifies, for the first time, a phytochelatin compound, phytochelatin 2 [γ-E-C-γ-E-C-G], and related metabolites in human urine. Phytochelatins are metal-binding peptides produced by plants. They are present in nearly all human diets, due to their ubiquity in plants.

Idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome with underlying history of malignancy.

Key Clinical Message: By reporting this case, we hope to emphasize the importance of maintaining a high index of clinical suspicion for the early recognition of RS3PE in patients presenting with atypical symptoms of PMR and underlying history of malignancy.

Abstract: Remitting seronegative symmetrical synovitis with pitting edema is a rare rheumatic syndrome of unknown etiology. It shares qualities with many other common rheumatological disorders such as rheumatoid arthritis and polymyalgia rheumatica, making diagnosis especially challenging.

Intestinal barrier dysfunction in murine sickle cell disease is associated with small intestine neutrophilic inflammation, oxidative stress, and dysbiosis.

The intestinal microbiome has emerged as a potential contributor to the severity of sickle cell disease (SCD). We sought to determine whether SCD mice exhibit intestinal barrier dysfunction, inflammation, and dysbiosis. Using the Townes humanized sickle cell mouse model, we found a 3-fold increase in intestinal permeability as assessed via FITC-dextran (4 kDa) assay in SS (SCD) mice compared to AA (wild type) mice ( = 4,  < 0.

Cyclic Adenosine Monophosphate (cAMP)-Dependent Phosphodiesterase Inhibition Promotes Bone Anabolism Through CD8 T Cell Wnt-10b Production in Mice.

Cyclic adenosine monophosphate (cAMP)-dependent phosphodiesterase (PDE) inhibitors such as pentoxifylline (PTX) suppress cAMP degradation and promote cAMP-dependent signal transduction. PDE inhibitors increase bone formation and bone mass in preclinical models and are used clinically to treat psoriatic arthritis by targeting inflammatory mediators including activated T cells. T cell activation requires two signals: antigen-dependent CD3-activation, which stimulates cAMP production; and CD28 co-stimulation, which downregulates cAMP-signaling, through PDE activation.

Impact of Financial Considerations on Willingness to Take Sacubitril/Valsartan for Heart Failure.

Background Sacubitril/valsartan improves health outcomes for heart failure with reduced ejection fraction relative to angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, but it carries higher out-of-pocket costs. Neither the impact of cost nor how to integrate cost into medical decisions is well studied. Methods and Results To evaluate the impact of out-of-pocket costs and a novel cost-priming intervention on willingness to take sacubitril/valsartan for heart failure with reduced ejection fraction, participants with self-reported heart disease were surveyed using the online Ipsos Knowledge Panel.

Aortic Dimensions Are Larger in Patients With Fibromuscular Dysplasia.

Background Fibromuscular dysplasia (FMD) is a disease of unknown etiology that causes stenosis, aneurysmal dilatation, and dissection of vascular beds. Known to affect medium-sized arteries, FMD is not typically considered to affect the aorta. We tested the hypothesis that aortic size in FMD is abnormal compared with age- and sex-matched controls.

Chronic Stroke Sensorimotor Impairment Is Related to Smaller Hippocampal Volumes: An ENIGMA Analysis.

Background Persistent sensorimotor impairments after stroke can negatively impact quality of life. The hippocampus is vulnerable to poststroke secondary degeneration and is involved in sensorimotor behavior but has not been widely studied within the context of poststroke upper-limb sensorimotor impairment. We investigated associations between non-lesioned hippocampal volume and upper limb sensorimotor impairment in people with chronic stroke, hypothesizing that smaller ipsilesional hippocampal volumes would be associated with greater sensorimotor impairment.

Troponin is unrelated to outcomes in heart failure patients discharged from the emergency department.
