Article Abstract

The Cape Verde palm tree, , holds significant ecological and cultural importance within the Cape Verde archipelago. However, its genetic distinctiveness has been questioned due to its close relationship and morphological similarity to the date palm (). In this study, we used an expanded sample set, 18 simple sequence repeat (SSR) markers, and a plastid minisatellite to characterize in Cape Verde and investigate its relationship with other species. Our findings identify genetic markers that differentiate the genetic pool, including a unique fixed allele. We also provide evidence of the recent divergence of from Northern African date palm populations, suggesting a relatively recent colonization of Cape Verde by palm trees. Additionally, we characterized the genetic composition of palm tree populations across three Cape Verde islands, concluding that wild samples from certain populations in Boavista and Sal are best suited for establishing a seed and/or germplasm bank for replantation efforts, representing a crucial step for the conservation of Cape Verde's natural heritage. Overall, our results enhance the understanding of the historical trajectories and genetic characterization of palm trees in Africa, offering valuable insights for conservation strategies.

A global prediction of cardiovascular disease from 2020 to 2030.

Front Cardiovasc Med

August 2025

Department of Clinical Epidemiology, Ningbo 2 Hospital, Ningbo, Zhejiang, China.

Background: The study aimed to forecast the incidence, mortality, and disability-adjusted life years (DALY) related to cardiovascular disease (CVD) across all age groups worldwide from 2020 to 2030.

Methods: Data spanning from 1990 to 2019 across diverse global populations were extracted from the GBD 2019 study data. Generalized Additive Models (GAM) were utilized to predict the disease burden for the period between 2020 and 2030.

Background: Routine surveillance is a pillar of malaria programmes, and the primary source of data used for decision making. However, any inference when relying on routine data to inform decision making is limited by how effective the system is at measuring the actual malaria burden. Here, we aimed to extend the Freedom From Infection (FFI) framework to produce species-specific estimates of surveillance system sensitivity and probability of freedom from malaria, combine multiple surveillance components including community case management and active case detection, and apply the FFI model in five malaria eliminating settings.
