Clinical Trials Monitor is a web application that connects in real time to the official APIs of ClinicalTrials.gov, openFDA, OpenAlex, and PubMed to provide a comprehensive view of active clinical trials and associated scientific evidence.

For each search, the app displays:

Active Clinical Trials: Retrieves active RECRUITING trials for any condition (e.g., lupus, diabetes, cancer) or drug (e.g., ibuprofen, sertraline, methotrexate). Returns up to 1,000 of the most relevant results (or total available if fewer exist), with filtering by country and sorting by relevance, last update, or start date. Displays key details: title, NCT ID, conditions, phase, location, and recruitment status.
Full Study Details: By clicking "View Details" on any trial, you can access a complete report including: official title, brief summary, detailed eligibility criteria (inclusion and exclusion), phase, enrollment number, study type, sponsor, start date, conditions studied, intervention, and location. The report can be downloaded as TXT or viewed directly on ClinicalTrials.gov.
Trial Insights: Automatic analysis of the most frequent conditions and most active countries among the retrieved trials.
FDA Safety Data: If you search for a drug, it shows the most reported adverse reactions. If you search for a condition, it shows the most frequently reported drugs linked to that condition (openFDA FAERS database).
Most Cited Papers: Top 20 most cited scientific papers related to the search term, sourced from OpenAlex.
Recent Papers: Latest 20 papers from the last 2 years, sourced from PubMed.

Dynamic Visualizations

This section features a series of dynamic visualizations I have developed covering diverse medical topics. These range from dynamic dashboards for clinical consultation to interactive semantic maps designed for exploring complex concepts and thematic clusters.

A) Artificial Intelligence and Neuroscience

The following visualization is based on the abstracts of 438 open-access articles collected from OpenAlex, covering the period 2020–2025.

Each node represents a concept, and the size of the nodes corresponds to the frequency with which that concept appears throughout the text. The edges represent co-occurrences between nodes, that is, the number of times those nodes appear close to each other in the analyzed text. The colors indicate themes grouped by thematic similarities, providing an overview of the ongoing work in this area.

▶ To interact with the network, click on the nodes of interest or use the zoom function to explore it in greater detail.

Some relevant themes and concepts observed in this semantic map are:

Neuroimaging and Computational Methods:
image, neuroimage, segmentation, algorithm, MRI, showing a strong focus on AI for brain image analysis.
Clinical Diagnosis and Neurological Disorders:
diagnosis, clinical, neurological, disease, neurodegenerative, reflecting applications of AI in medical decision-making and early detection.
Neurointervention and Psychiatry:
