Researchers try new ways of preserving more hearts for transplants
Two university hospitals are pioneering new ways to expand lifesaving heart transplants for adults and babies—advances that could help recover would-be heart donations that too often go unused.

1.719. Alcohol-damaged liver cells form 'pseudosynapses' to trigger inflammation

  • 1 month ago schedule

Excessive alcohol consumption causes alcoholic liver disease, and about 20% of these cases progress to alcohol-associated steatohepatitis (ASH), which can lead to liver cirrhosis and liver failure. Early diagnosis and treatment are therefore extremely important.

1.720. Ultra-high-resolution MRI maps brain fibers and cells with near-micron precision

  • medicalxpress.com language

A scientific team supported in part by the National Institutes of Health (NIH) has developed a new, ultra-high-resolution brain imaging system that can reconstruct microscopic brain structures that are disrupted in neurological and neuropsychiatric brain disorders. The new system is a significant advance over conventional magnetic resonance imaging (MRI) scanners that cannot visualize these tiny but clinically important structures.

  • medicalxpress.com language

Artificial intelligence (AI) models trained on large datasets are increasingly seen as the key to unlocking personalized treatments for brain disorders. An important bottleneck for scaling AI is the cost of data collection. This raises a fundamental dilemma: is it more cost-effective to scan more people for a short time, or fewer people for longer?

1.729. RHA meets to accelerate action on polio eradication and maternal, newborn and child health

17 July 2025, Cairo, Egypt – The Regional Health Alliance (RHA) convenes today to accelerate efforts to improve maternal, newborn and child health and support immunization and polio eradication across the World Health Organization (WHO) Eastern Mediterranean Region. The meeting will gather representatives from nine UN agencies and six priority countries – Afghanistan, Djibouti, Pakistan, Somalia, Sudan and Yemen. Hosted by WHO Regional Office for the Eastern Mediterranean, the one-day meeting aims to strengthen support for Member States as they implement national strategies to reduce maternal, newborn and child mortality, eradicate polio and boost immunization coverage through the Expanded Programme on Immunization. Recent data indicate that 60 countries globally are not on track to meet the Sustainable Development Goal (SDG) targets on under-5 mortality, and 65 are off track for the neonatal mortality target. In 2023, the six  priority countries accounted for almost 85% of under-5 deaths (694 000 out of 812 000) in the Eastern Mediterranean Region and recorded some of the highest maternal mortality rates globally, ranging from 155 to 563 per 100 000 live births. Participants will discuss ways to enhance efforts, renew commitment and increase investment in maternal, newborn and child health to help countries achieve the SDG targets adopted by UN Member States in 2015, including reducing maternal mortality to less than 70 per 100 000 live births and ending preventable deaths of newborns and children under 5 by 2030. Recognizing the urgent need for action, WHO, the United Nations Children’s Fund (UNICEF) and the United Nations Population Fund (UNFPA) are collaborating Read more...

1.730. Regional Coalition for Mental Health and Substance Use Prevention launches in Cairo

  • emro.who.int language

17 July 2025, Cairo, Egypt – Today, the World Health Organization (WHO) Regional Office for the Eastern Mediterranean joined with mental health partners and stakeholders to launch the Regional Coalition for Mental Health Promotion and Substance Use Prevention. The Coalition will provide a platform to align strategies and maximize collective impact. Stakeholders will be able to transform how mental health, psychosocial support and substance use are addressed across the Region and facilitate the urgently needed shift from stigmatization to empowerment, punishment to prevention, isolation to integration and fragmentation to coordinated, impactful action. Tackling mental health conditions and substance use poses a major challenge at both the global and regional level. In today’s context of shrinking resources and growing needs, unified strategic actions are required. No single sector or agency can address the pressing challenges alone. The Coalition brings together civil society actors working on the frontlines of mental health and substance use, many led by people who have been directly affected. Their work spans prevention, rehabilitation, advocacy, service delivery and policy reform. People with lived experience are a vital resource and must be engaged with as equal partners and leaders, not as beneficiaries or symbols. Mental health conditions and substance use disorders exact a devastating toll across the Eastern Mediterranean Region – on individuals, families and communities. One in 6 people in the Region lives with a mental health condition. Substance use is on the rise, with 6.7% of adults affected – above the global average – of whom only a fraction receive treatment.
