Hospital delirium a 'red flag' for severe health decline

Delirium is an acute, fluctuating state of confusion, reduced awareness, and cognitive impairment, typically developing over hours or days due to underlying medical issues, infections, medication side effects, or substance withdrawal. Symptoms include hallucinations, poor focus, and emotional changes, categorized into hyperactive, hypoactive, or mixed types. It often lasts about one week but can persist, and it is most common in older adults or those hospitalized in intensive care.
Hospitalized older adults experiencing delirium face significantly increased risks of adverse outcomes, including doubled rates of falls and urinary incontinence, and 50–70% higher risks of pneumonia, fractures, stroke, sepsis, acute kidney injury, and pressure injuries. Delirium indicates multisystem vulnerability and warrants extended post-discharge care and prevention strategies.

Researchers found delirium was associated with a higher risk of 12 adverse outcomes, independent of frailty and pre-existing dementia, which shows it is a warning of longer-term vulnerability.
An episode of delirium in hospital doubled the risk of falls and urinary incontinence, and there was a 50% to 70% increased risk of pneumonia, fecal incontinence, fractures, stroke, hip fracture, sepsis, acute kidney injury, and pressure injury.

There was also a 20% to 30% higher risk of gastrointestinal bleeding and heart failure. These are very strong associations that highlight delirium as a red flag for multisystem vulnerability.

Scientists make Parkinson's drug from plastic in world first
Engineered E. coli bacteria can convert polyethylene terephthalate (PET) plastic waste into levodopa, a key Parkinson’s disease treatment, offering a sustainable alternative to fossil fuel–based drug production. Similar biotechnological approaches have also enabled conversion of plastics into other pharmaceuticals, supporting the potential for a circular economy that repurposes plastic waste into valuable medicines.

Carb-heavy foods drove weight gain without more calories by lowering energy burn

Carbohydrate-rich foods such as bread, wheat, and rice increased body weight and fat mass in mice without a significant rise in total caloric intake, primarily by reducing energy expenditure rather than promoting overeating. Metabolic changes included elevated blood fatty acids, decreased essential amino acids, hepatic fat accumulation, and upregulation of genes involved in lipid synthesis and transport. Discontinuing wheat flour intake rapidly reversed weight gain and metabolic abnormalities.
