Pediatric intensive care units (PICUs) in low and middle-income countries see elevated mortality rates, often 10 times higher than those in high-income countries. One leading risk factor is the high incidence of unplanned intubation — a procedure that inserts a tube into the child’s airway — which can lead to complications like hypoxia and ventilator-associated pneumonia. Interventions that improve clinical practices can help reduce child mortality in countries with limited resources. In a new study published June 12th in Frontiers of Public Health, investigators from Mass ...

There are various types of widow spiders, including black, red, and brown varieties in North and South America, the Australian redback spider, and several button spider species that inhabit South Africa. In Europe, Latrodectus tredecimguttatus – the European black widow – inhabits the Mediterranean region, but recently and due to the changing climate, the widows have been expanding their habitat. Widow spiders’ bites can cause latrodectism, a disease where the spider’s venom, a neurotoxin known as alpha-latrotoxin, attacks the nervous system and causes symptoms like severe ...

The felt age of spousal caregivers is connected to the felt age of their loved ones living with dementia, according to a study from the University of Surrey. This perceived age in people with dementia and their caregivers is related to their own wellbeing, satisfaction with life, and self-confidence.  Felt age is defined as how old someone feels compared to their real age. It's measured by asking people to report whether they feel younger, the same, or older than their actual age. This concept helps understand how people see their own ageing, which can affect their mental and physical health and predict important ...
