Evidence-based medicine (EBM) is defined as "the process of systematically finding, appraising and using contemporaneous research findings as the basis for clinical decisions". Although EBM has been extensively described across the Americas and Europe, no study has looked at the practice of EBM in Puerto Rico. A cross-sectional analysis based on a 23-item questionnaire was employed. We showed that there is a high use (88%) and familiarity (93%) with EBM, and that physicians keep a positive attitude towards EBM (80%) in Puerto Rico. There is an over-representation of academicians (58.9% vs. 34.6%, p = 0.02) and an under-representation of solo office practitioners (10.5% vs. 26.9%, p = 0.03) among EBM users. Additionally, patient workload (48%), time constraints (36%), and limited access to the Internet (28%) were the most frequently cited obstacles to the practice of EBM in Puerto Rico. Taken together, these results help create a cross-sectional profile of EBM practice among Puerto Rican physicians.

Bacterial burden and drug-resistant bacteria in healthcare workers' mobile phones: a study in Puerto Rican outpatient clinics.
Infect Prev Pract
March 2025
San Juan Bautista School of Medicine, Caguas, Puerto Rico.
Background: Mobile phones used by healthcare workers (HCWs) in hospitals are significant reservoirs of drug-resistant bacteria responsible for hospital-acquired infections (HAIs).
Aim: The objective of this study was to assess the level of contamination with such bacteria in outpatient clinics.
Methods: Swabs from 83 HCWs' mobile phones were processed using standard biochemical and enzymatic procedures to identify pathogenic bacteria.
Nicotinic Acetylcholine Receptor Expression in Merkel Cell Carcinoma Is Associated With Clinical and Histopathologic Parameters.

Background: Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous malignancy with neuroendocrine differentiation. Several molecular pathways have been implicated in MCC development and multiple cell-of-origin candidates have been proposed, including neural crest cells, which express acetylcholine receptors (AChRs). The role of nicotinic acetylcholine receptors (nAChRs) in MCC has not been explored.

Coral reefs can mitigate flood damages by providing protection to tropical coastal communities whose populations are dense, growing fast, and have predominantly lower-middle income. This study provides the first fine-scale, regionally modeled valuations of how flood risk reductions associated with hybrid coral reef restoration could benefit people, property, and economic activity along Florida and Puerto Rico's 1005 kilometers of reef-lined coasts. Restoration of up to 20% of the regions' coral reefs could provide flood reduction benefits greater than costs.

Clin Exp Dermatol
January 2025
School of Medicine, Universidad Central del Caribe, Bayamón, Puerto Rico.
This study investigates the differential activation of the epithelial-mesenchymal transition (EMT) pathway in metastatic melanoma, focusing on BRAF- and NRAS-mutated samples from The Cancer Genome Atlas (TCGA). Gene Set Enrichment Analysis (GSEA) reveals that BRAF mutations are more significantly associated with increased EMT activation, relative to all other mutations in the dataset. In contrast, NRAS mutations were not significantly associated with gene expression of the EMT pathway, suggesting alternative mechanisms for metastasis.

Plague is a rare, potentially fatal flea-borne zoonosis endemic in the western United States. A previous model described interannual variation in human cases based on temperature and lagged precipitation. We recreated this model in northeastern Arizona (1960-1997) to evaluate its capacity to predict recent cases (1998-2022).
