Global mortality rates are falling but not among youths and young adults, according to the latest Global Burden of Disease (GBD) study published in The Lancet today and presented at the World Health Summit in Berlin.

People who experience food insecurity or loneliness are much more likely to develop chronic pain after surgery, according to new research presented at the ANESTHESIOLOGY® 2025 annual meeting.

Most children - including nearly 80% of infants - go without clear liquids before surgery for at least twice as long as guidelines recommend, according to an analysis of data on more than 70,000 children presented at the ANESTHESIOLOGY 2025 annual meeting.

Researchers have shown that young rats fed a ketogenic diet – a diet with high fat and low carbohydrates – are protected from the lasting experience of pre-natal stress.

It is known that depression is linked to increased incidence of metabolic diseases; now scientists have discovered that different types of depression are linked to different cardiometabolic diseases. This work is presented at the ECNP Congress in Amsterdam.

Older patients who primarily speak a language other than English may face a greater risk of developing delirium after surgery in U.S. hospitals, according to new research presented at the ANESTHESIOLOGY 2025 annual meeting. The

New mothers are more likely to experience severe pain that disrupts sleep and activities of daily living, as well as develop sleep disorders, if they give birth by cesarean delivery (C-section), suggests research presented at the ANESTHESIOLOGY 2025 annual meeting.

Overdose deaths in adults age 65 and older from fentanyl mixed with stimulants, such as cocaine and methamphetamines, have surged 9,000% in the past eight years, matching rates found among younger adults, according to research presented at the ANESTHESIOLOGY 2025 annual meeting.

This review examines how Western dietary patterns, high in ultra-processed foods, salt, and unhealthy fats, disrupt gut microbiota, impair immune regulation, and contribute to the global rise of inflammatory bowel disease (IBD). It highlights systems biology and nutritional epidemiology as essential tools to develop personalised dietary strategies and shift IBD care from treatment to prevention.

A Swedish-led study validated a self-administered digital cognitive test (BioCog) in primary care, showing it can accurately detect objective cognitive impairment before blood biomarkers are applied. When paired with a targeted amyloid blood test, this stepwise pathway outperformed standard assessments for diagnosing clinical Alzheimer’s disease.

This global analysis shows that the biodiversity impact of producing 1 kg of food can vary by up to 1,000-fold, with ruminant meat and tropical luxury crops carrying the highest extinction risks. Using the LIFE metric, researchers reveal how national diets and food imports contribute to hidden biodiversity losses, highlighting dietary shifts as a powerful conservation tool.

Self-administered dried blood spot kits show potential for cardiometabolic screening in young adults, but success relied heavily on clear guidance and researcher support. High rates of at-risk biomarkers highlight an urgent need for early prevention in this population.

Researchers modeled drone-based medication delivery across Virginia’s isolated Eastern Shore, finding it could cut travel times from nearly 50 minutes by car to under 10 minutes for most residents. By mapping age, flood risk, and access barriers, the study highlights how targeted drone networks could improve health equity in rural, disaster-prone regions.

Teenagers who experienced higher COVID-19 stress during remote schooling were more likely to become open to trying vaping, which significantly increased their odds of using e-cigarettes and cannabis two years later. The study reveals that susceptibility, not immediate use, was the critical pathway linking early stress to later vaping behaviors.

Researchers analyzing over 2,100 adults from the MIDUS cohort found that individuals with higher cumulative social advantage, spanning community ties, family relationships, and religious support, showed slower biological aging and lower systemic inflammation. The findings suggest that long-term social resources may become biologically embedded, influencing molecular pathways linked to longevity.

Although the home environment is known to influence behavior problems in children with developmental disabilities (DD), the precise contributions of specific domains remained unquantified, hindering targeted interventions.

New research confirms that ADHD (Attention Deficit Hyperactivity Disorder) can be linked to increased creativity and suggests that this creativity is associated with a greater tendency to let your mind wander.

Speech rhythm, a key attribute of natural languages that directly influences the effectiveness and efficiency of communication, is often compromised in people with neurodegenerative diseases such as Amyotrophic Lateral Sclerosis, or ALS.

Scientists have found that ADHD (Attention-Deficit/Hyperactivity Disorder) in women is diagnosed approximately 5 years later than in men, despite symptoms appearing at the same age.

A new Kinsey Institute study has found gaps in sex education can have lasting impacts throughout adulthood, including relationship struggles, lack of confidence, and reduced quality of life.
