North-south pathways, emerging variants, and high climate suitability characterize the recent spread of dengue virus serotypes 2 and 3 in the Dominican Republic.

Background: Dengue fever remains a significant public health challenge in tropical and subtropical regions, with its transmission dynamics being influenced by both environmental factors and human mobility. The Dominican Republic, a biodiversity hotspot in the Caribbean, has experienced recurrent dengue outbreaks, yet detailed understanding of the virus's transmission pathways and the impact of climatic factors remains limited. This study aims to elucidate the recent transmission dynamics of the dengue virus (DENV) in the Dominican Republic, utilizing a combination of genomic sequencing and epidemiological data analysis, alongside an examination of historical climate patterns.

Effect of cyclosporine A on serum tumor necrosis factor alpha in new-onset type I (insulin-dependent) diabetes mellitus.

Because the etiology of insulin-dependent diabetes mellitus (IDDM) is thought to be autoimmune, several clinical trials have utilized immunosuppression to treat newly diagnosed diabetic patients. In the University of Miami trial, cyclosporine A (CyA) was used to treat one group (n = 10), while the other received placebo (n = 13). During the 1-year study, islet beta-cell function was better preserved in the CyA group compared to the placebo group, based on the response (C-peptide production) to a physiologic stimulus (meal challenge).
