Poor lung gas exchange may help explain lingering brain symptoms in Long COVID

This study found that people with Long COVID more than two years after infection showed normal lung tests and brain structure, yet reported significant sleep and cognitive symptoms. Subtle correlations revealed that poorer lung gas exchange was linked with higher brain perfusion, worse sleep, and weaker executive function, suggesting a possible lung–brain connection.

Moderate coffee intake linked to slower biological aging in people with severe mental illness

Drinking a maximum of 3-4 cups of coffee a day may slow the 'biological' ageing of people with severe mental illness, by lengthening their telomeres-indicators of cellular ageing-and giving them the equivalent of 5 extra biological years, compared with non-coffee drinkers, finds research published in the open access journal BMJ Mental Health.

Blocking immune cell signals reduces scar tissue formation in wounds

Researchers at the University of Arizona uncovered a previously unknown population of circulating immune cells that play a critical role in fibrosis, the buildup of scar tissue that can lead to organ failure and disfigurement.

'Myeloid mimicry' identified as driver of immunotherapy resistance in renal medullary carcinoma

Researchers at The University of Texas MD Anderson Cancer Center have found that renal medullary carcinoma (RMC) cells use an adaptive mechanism called "myeloid mimicry" to hide from the immune system and promote disease hyper progression after immunotherapy, highlighting specific targets that overcome treatment resistance in preclinical models.

Obesity-related metabolic stress may affect brain health far earlier than expected

For decades, scientists have known that what harms the body often harms the brain. Conditions such as obesity, high blood pressure and insulin resistance strain the body's vascular and metabolic systems.

Shorter hormone therapy may be enough for many men with prostate cancer

A study co-led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center found that most of the benefits of androgen deprivation therapy (ADT) for prostate cancer occur within the first 9 to 12 months.

Global data show why gut microbiomes in industrialized regions look increasingly alike

Researchers studying more than 1 000 adults across 12 countries found that industrialization is one of the strongest forces reshaping the human gut microbiome, reducing diversity and stability. Industrialized and urban populations also showed higher immune and gut stress markers, suggesting physiological consequences of these altered microbial communities.

Early treatment after head injury lowers long-term risk of Alzheimer’s disease

Getting treatment within one week of a serious head injury can reduce the risk of developing Alzheimer's disease by up to 41%, according to new research from Case Western Reserve University.

Retrospective analysis shows mortality rates and risk factors after prosthetic heart valve surgeries

Mechanical valve replacement is a primary treatment for rheumatic heart disease, yet prosthesis-related adverse outcomes remain underreported in India.

White matter alterations connect coronary artery disease to cognitive decline

Individuals with coronary artery disease (CAD) - a constricting or blocking of blood vessels feeding the heart - face increased risks of strokes, cognitive impairment and dementia. However, the link between CAD and cognitive function is not fully understood.

Study overturns assumptions about PTPN22 risk gene’s role in interferon production

A new paper from the University of Kansas overturns the idea that a "risk gene" carried by millions of people worldwide influences production of Type 1 interferon, a workhorse of the immune system.

Long-term calorie restriction can slow cellular markers of brain aging

As the brain ages, cells in the central nervous system experience metabolic dysfunction and increased oxidative damage.

How immune signals activate brain circuits to drive sickness-induced social withdrawal

MIT researchers have discovered how an immune system molecule triggers neurons in a specific brain circuit to shut down social behavior in mice modeling infection.

Prefrontal cortex modulates visual and motor regions based on internal feelings

Vision shapes behavior and, a new study by MIT neuroscientists finds, behavior and internal states shape vision.

Assessment of pre-procedure versus spray-as-you-go airway anesthesia protocols in bronchoscopy

Fiberoptic bronchoscopy involves various topical airway anesthesia protocols, which can impact patient comfort, procedural ease, and overall outcomes.

Daily walking patterns help flag early Parkinson’s signs in large UK study

Accelerometer data from nearly 95,000 adults show that higher daily step counts predict lower short-term Parkinson’s disease risk. But as follow-up extends, the association fades, indicating that reduced steps are more likely an early marker than a cause.

Genetic signals reveal why erectile dysfunction develops and who is most at risk

This multi-ancestry genomic study identifies key genetic loci underlying erectile dysfunction and shows that ED risk is shaped by both cardiometabolic and substance use–related genetic pathways. Using EHR-linked data, the researchers uncover SIM1-related mechanisms, modest PRS performance, and bidirectional genetic links with obesity, diabetes, and addiction traits.

Laparoscopic biliary atresia surgery in newborns reduces blood loss, improves jaundice recovery

Nagoya University researchers and their collaborators have found that minimally invasive laparoscopic surgery significantly reduces blood loss and improves jaundice recovery compared to traditional open surgery for treating biliary atresia-a serious liver condition in newborns.

Extreme heat waves pose death risk for veterans with cardiometabolic conditions

Veterans living in California who have cardiometabolic conditions such as diabetes and high blood pressure experience significantly higher risk of dying during heat waves compared to cooler days, UCLA-led research finds.
