New research on cigarette smoking uncovers the dangers of low-level smoking, how long it takes to get back to baseline health after quitting

A study published in the Journal of Patient Experience, with the participation of the D'Or Institute for Research and Education (IDOR), analyzed the perceptions of over 47,000 healthcare professionals on institutional efforts to improve patient experience in private hospitals in Brazil. The research indicated that engaging care teams remains the biggest challenge for concrete improvements in the quality of care.

Eating moderate amounts of lean beef as part of a Mediterranean diet does not increase an emerging risk factor for cardiovascular disease, according to a new study by an interdisciplinary research team at Penn State. The researchers examined indicators of heart health and gut microbiome diversity among relatively young and healthy participants who ate four different diets, including varying amounts and types of beef, for four weeks.

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.

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.

A new heart monitoring system combining 3D printing and artificial intelligence could transform the way doctors measure and diagnose patients' heart health.

Developed at SFU’s School of Mechatronic Systems Engineering, the system features reusable dry 3D-printed electrodes embedded in a soft chest belt – the folding origami-shaped design uses gentle suction to stick to the skin.

Carbon-based ink printed on the suction cup replaces electrolyte gel, conducting the heart’s electrical signals through to a wearable device with built-in AI software to pre-diagnose of up to 10 types of arrhythmias, or irregular heart rhythms.
