Real-World Example: How Researchers Use PubMed.ai
Scenario 1: Writing a Literature Review
Search: “immunotherapy for metastatic melanoma”
- AI summarizes 20+ key studies
Result Summary
Immunotherapy has emerged as a crucial treatment for melanoma, particularly for metastatic cases. Approaches such as checkpoint inhibitors (e.g., PD-1/CTLA-4 inhibitors) and targeted therapies have shown significant efficacy, enhancing patient outcomes by promoting T-cell responses against tumor cells. Additionally, combination therapies and novel strategies, including mRNA vaccines, are being explored to further improve immune responses and overcome resistance in melanoma treatment.

Scenario 2: Clinical Decision Support
- Search: “COVID-19 antiviral treatments for elderly”
- AI provides treatment evidence summary
Result Summary
The efficacy of antiviral agents for elderly COVID-19 patients has shown mixed results. In particular, studies indicate that antivirals like remdesivir reduce mortality in hospitalized patients but may not significantly benefit those with severe comorbidities. Furthermore, treatments such as nirmatrelvir/ritonavir demonstrate a protective effect against long-term complications like stroke. Therefore, tailored antiviral strategies are essential for this vulnerable group.
