Heart disease remains the leading cause of death in Brazil, with over 237,000 fatalities in 2024. A study published last year reveals that even among Brazilians diagnosed with arterial diseases, only a tiny fraction follows the full recommendations for cardiovascular prevention. Coordinated by the Hcor Research Institute with participation from the D’Or Institute for Research and Education (IDOR), the NEAT initiative showed that just 0.3% of patients with atherothrombosis adhere to all recommended medical practices to reduce the risk of heart attacks and strokes. The results were published in the journal Scientific Reports.

A survey published in the International Journal of Retina and Vitreous compiled 68 studies to map out how generative artificial intelligence, especially ChatGPT, is being used by professionals in healthcare, particularly in ophthalmic care. The review, which included the participation of the D’Or Institute for Research and Education (IDOR), shows how tools based on large language models (LLMs) are gaining ground in medical routines, especially for triage, preliminary diagnoses, and medical education.

Assessing the severity of illness in critically ill patients is a crucial task in Intensive Care Units (ICUs) worldwide. However, current systems are often based on local realities and can fail when applied to international contexts. An article published in the journal Critical Care Science, co-authored by researchers from the D'Or Institute for Research and Education (IDOR), argues that an international scoring system is urgently needed for intensive care medicine research and for the advancement of global public health.

Bladder cancer ranks among the ten most common types of cancer worldwide. The main treatment is bladder removal surgery, and despite advances in systemic therapies, recurrence is frequent in the most aggressive forms of the disease. For this reason, researchers have been seeking less invasive and more effective strategies to fight it.

A study involving the D’Or Institute for Research and Education (IDOR) and published in Biochemical Genetics points to a promising path: by blocking a small molecule called miR-21, bladder cancer cells lose their ability to multiply and spread. This discovery could pave the way for future therapies that are both less invasive and more precise.

A study published in the Journal of Critical Care, conducted with the participation of the D’Or Institute for Research and Education (IDOR), investigated how to measure efficiency in the use of resources for patients with severe community-acquired pneumonia (CAP), an illness contracted outside hospital settings and most common among older adults.

Severe CAP represents one of the greatest challenges for ICUs. It requires complex resources, ranging from prolonged hospitalizations to respiratory support, directly affecting hospitals’ ability to deliver quality care. Despite its relevance, traditional methods of evaluating hospital performance do not always take patient severity into account, which undermines fair comparisons between institutions and hinders more effective management strategies.

Published in the Global Journal on Quality and Safety in Healthcare, a study led by D’Or Institute for Research and Education (IDOR) researchers, Dr. Helidea Lima and Dr. Leopoldo Muniz, examined how hospital accreditation influences patient safety culture in Brazilian hospitals. The publication was highlighted in the journal’s editorial, reinforcing the importance of this research conducted in Brazil.

Digital technology—and especially the Internet—has revolutionized the way we work, study, socialize, and entertain ourselves. Alongside the global increase in screen time, both public and academic attention to potentially addictive digital behaviors has grown.

One such behavior is online pornography consumption. A study published in Addictive Behaviors, conducted by researchers from Monash University (Australia), the D’Or Institute for Research and Education (IDOR), and the Federal University of Rio de Janeiro (UFRJ), investigated problematic pornography use (PPU), particularly in men.
